Description

Detergent products, methods and manufacturing.

Technical field

The present invention is in the field of dishwashing, specifically refers to a bag water-soluble multicompartmental adapted to fit the dishwasher dispenser and release product in prewash, main wash cycles and / or cycle post-rinse of the automatic dishwasher. The bag It contains a cleaning composition that is released when it is produced The dissolution of the bag.

Background of the invention

Some consumers find that the doses unit detergent detergents are more attractive and comfortable because they avoid the need for the consumer to measure the product, thus creating a more precise dosage and avoiding a wasteful overdose or insufficient dosage. By This reason, automatic dishwashing detergent products Pill-shaped have become very popular. The products Bag-shaped detergents are also known in the art, they also have the advantage over the pads to avoid contact of the consumer's fingers with the composition for washing dishes that may contain bleach and / or other substances irritating

The process for automatic dishwashing usually involves an initial prewash cycle, a cycle of main wash and several rinse cycles. They get better results when the detergent is released at the beginning of the cycle of main wash than when the detergent is released in the cycle of prewash since this can be lost with the initial water. In washing machines for washing clothes, detergent can be placed in the drum or in the dispenser, however, in the dishwashers, the detergent is usually released in the main wash by the dispenser to prevent premature dissolution in the prewash. The amount of detergent is therefore limited by the volume of the dispenser. Dispensers vary in volume and shape between different manufacturers. In the case of loose detergent (it is say, powders, paste and liquids), the volume of the dispenser is a decisive factor. In the case of unit dose forms, such as a tablet, the geometry and shape of the dispenser also play a very important role.

The pads can be designed to have A size and shape that suits all dishwashers. One of the disadvantages of detergent tablets is the fact that their manufacturing process requires the additional stage of the powder compaction. This stage reduces the enzymatic activity and slows the dissolution rate of the ingredients that make up the tablet, or requires the use of systems complex and expensive disintegrants or it is difficult to achieve differential dissolution of the active ingredients of the Detergent.

Some detergent components used in Detergent compositions for dishwashing are liquid. It may be difficult or expensive to include these liquid ingredients in a solid detergent composition. Therefore determined ingredients are preferably transported and supplied to manufacturers of detergents in liquid form, requiring stages of additional and sometimes expensive processing to include in a solid detergent composition. An example of these Detergent ingredients is the surfactant, especially the nonionic surfactant, which is typically liquid to room temperature or is typically transported and supplied at Liquid detergent manufacturers. Another example are Organic solvents

Current methods to incorporate liquid ingredients in solid detergent compositions include the absorption of the liquid ingredient in a solid vehicle, for example, by mixing, agglomeration or spraying techniques. Typically, solid detergent compositions comprise only small amounts of these liquid detergent ingredients due to the difficulty and cost of incorporating these ingredients liquids in a solid detergent. In addition, the incorporation of Liquid ingredients in solid detergent compositions can affect the dissolution characteristics of the composition (by example, as a consequence of the formation of the gel phases of the surfactant), can increase moisture absorption by water sensitive ingredients and can also cause problems with fluency. It would be advantageous to have a detergent composition that allow the different ingredients to be in their natural state, that is, liquid or solid. This would facilitate the process of manufacturing, would increase the stability of the component and also would allow the release of liquid ingredients before or after the release of solid ingredients. For example, the differential dissolution of the active ingredients would be beneficial in the case of enzyme / bleach compositions for avoid oxidation of enzymes by the bleach in the solution for dishwashing. It would also be advantageous to separate the perfume bleach.

Another factor that can contribute to liberation ineffective of the active substances to the wash solution, in the case of the pills, it is the need to add materials vehicles, such as porous materials capable of bonding active liquid materials, binders and disintegrants. In in particular, the incorporation of surfactant liquids into detergent compositions in powder form may cause considerable processing difficulties and also the problem of a bad solution due to the formation of surfactant phases in gel

There is still a need for a multicompartmental unit dose form capable of adapting to the dispensers of different types of dishwashers and that allow the simultaneous release of incompatible ingredients and Ingredients in different physical forms. There is also the need for a simplified manufacturing process for the production of a multi-compartment bag and for the production of multi-compartment bags with characteristics of improved resistance, handling and dissolution, as well as a excellent aesthetics

The multicompartmental bags are already known in the art, see for example EP patents 0414462-A, EP-0593952-A and the WO application 0183669-A.

The most common procedure for the production of water-soluble bags with products, such as cleaning products It is the filling-sealing process in mold vertical. Through this, a vertical tube is formed by folding a movie. The lower end of the tube is sealed forming a open bag This bag is partially filled leaving a space at the head whereby the top of the open bag is subsequently seal each other to close the bag and lead to The next open bag. The first bag is cut later and the process is repeated. Bags formed in this way have usually pillow form.

A second known procedure for bag production is by using a matrix that has a series of molds and shaping from a bag film open in these molds, which are then filled and seal. This method uses the film-shaped material of more effectively and the process has more flexibility in terms of Bag forms and ingredients used. However the procedure has a limited suitability for the application industrial, because it cannot produce large quantities of bags (per unit of time) in an easy and effective way.

A third proposed process is the formation of bags in the molds present on the surface of a drum circular. Through this process, a film is circulated through the drum and bags are formed, which pass under one filling machine filling the open bags. Filling and sealed have to take place at the highest (upper) point of the circle described by the drum. p. e.g., typically filling is done just before the rotating drum starts the circular movement down and sealing just after The drum starts its downward movement.

A problem associated with the filling machine vertical is that the process is not very effective: the process is intermittent and very slow, for example, due to changes in process speed between one stage and the next stage and each bag formation stage typically results in only one row of bags in one dimension; therefore, it can only be formed A quantity of bags per minute. In addition, large are used quantities of film per dose of product because the method does not allows the complete filling of the bags and there is a gasket considerable along the vertical dimension of each bag and the method does not allow the stretching of the film. In addition, it does not exist a lot of flexibility in the shapes of the bags formed.

The problems associated with the second procedure which uses a matrix with molds also include the fact that the process is intermittent (or an indexing process) and that the process is slow and involves acceleration and deceleration, which reduce the overall speed and also causes the spill of Product from open bags. Therefore, the performance of This process is not very high (per unit of time).

The circular drum process overcomes some of the disadvantages of these procedures because it does not allow changes of speed (no acceleration / deceleration) and can provide easily bags arranged in two dimensions and the shape of the Bags may vary to some extent. However, the spill since the bags can be quite important, due to the movement circular, which causes the product to be poured into the area of sealing and this causes problems with sealing (gaskets leakage). Therefore, the process does not allow the bags to be filled completely because the spill is more than a problem. So this procedure has even more important problems when used for liquid products, which are more likely to cause a major spill due to circular motion. In addition, the filling and sealing has to be done around the most point high of the circular travel of the drum, thus reducing greatly the overall speed and performance of the process of the formation of the bag.

All known processes are also designed primarily to manufacture bags with a single compartment There is still a need for a procedure to manufacture water-soluble multicompartmental bags that solve the aforementioned problems, specifically of a continuous procedure with a fast production speed and that minimizes the amount of film used for each bag. There is also a need for a manufacturing process for water-soluble multi-compartment bags with a resistance enhanced and adapted for use in the automatic dishwasher.

Summary of the invention

According to a first aspect of the present invention, a product for machine dishwashing is provided in Shape of a water-soluble bag. The bag comprises a plurality of compartments in a generally superimposed relationship, by For example, the plurality of behaviors can be symmetrically arranged on top of each other. Each compartment Contains one or more detergent active components or substances auxiliary detergents. Water-soluble bags that comprise a plurality of compartments are defined here as bags multi-compartment Multi-compartment bags in which the compartments are in an overlapping relationship are especially advantageous when one or more of the compartments they comprise a moisture sensitive ingredient, since the compartment comprising a moisture sensitive ingredient is you can place in an intermediate or lower layer and thus have an area shallow surface exposed to the surrounding environment, therefore reducing the possibility of moisture absorption of environment.

The bag has a first compartment that it comprises a liquid composition and a second compartment that It comprises a powder composition in which the weight ratio between the liquid and solid composition is from 1:30 to 30: 1 and has a volume of 5 to 70 ml, preferably 15 to 60 ml, more preferably 18 to 57 ml and a dimensional ratio longitudinal / transverse in the range of 2: 1 to 1: 8, preferably from 1: 1 to 1: 4. The longitudinal dimension is defined. as the maximum height of the bag when the bag rests on a of the bases which has the maximum profile with the compartments of the bag superimposed in a longitudinal direction, that is, one over another and under a static load of 2 Kg. The dimension transverse is defined as the maximum width of the bag in a plane perpendicular to the longitudinal direction in the same conditions. These dimensions are suitable to fit the dispensers of most dishwashers. Although the shape of the bag can vary a lot in order to maximize the available volume, the Preferred bags have a base as similar as possible to the profile of most dispensers, that is generally rectangular.

In one embodiment, the bag comprises walls upper and lower outer generally opposite walls edge-like sides, forming the sides of the bag and one or more internal partition walls, separating different compartments with each other and in which each of the walls upper and lower exteriors and the edge-like side is formed by thermoforming, vacuum forming or a combination thereof.

Therefore, according to another aspect of the invention, a product for machine dishwashing is provided in the shape of a water-soluble bag comprising a plurality of compartments in generally superimposed relationship, containing each compartment one or more detergent active substances or auxiliary components, where the bag has a first compartment comprising a liquid composition and a second compartment comprising a powder composition wherein the ratio between the liquid and the solid composition is from 1:30 to 30: 1, where the bag comprises upper outer walls and generally opposite bottoms, a side wall as an edge and one or more walls of internal division and where each of said upper and lower outer walls and the side wall as an edge they are formed by thermoforming, conformation to empty or a combination thereof.

In a preferred embodiment each wall of internal division of the multicompartmental water-soluble bag is fixed to an outer or side wall of the bag along a single joint line or both to the outer wall and to the wall side of the bag along a plurality of joint lines which at least partially do not overlap. Preferably every partition wall is attached to one or more exterior walls or lateral by heat sealing or sealing with solvents.

In especially preferred embodiments such as minimum one wall of internal division of the multicompartmental stock exchange is fixed to an upper or lower outer wall along a first continuous joint line and one or both of said walls exteriors and of said partition wall are fixed to the wall lateral as an edge along a second joint line continues and where the joint lines in the case of heat sealing they are essentially non-overlapping and in the case of sealing with solvent, at least partially they are not superimposed.

The non-overlapping joint lines are especially advantageous in the case of multi-compartment bags manufactured using a procedure that involves several stages of Heat sealing not simultaneous. Without imposing any theory, it is believed that The sealing mechanism involves the stage of water evaporation of the film, therefore it is very difficult to get a good sealed superimposed unless two joints are formed simultaneously. Heat sealing is preferred in cases where which bags are filled with water sensitive components. He Solvent sealing can reduce the cost of processing, It can reinforce the joints and can speed up the process. The boards partially non-overlapping allow the superposition of a plurality of compartments of different sizes.

Preferably, at least one wall of internal division of the multicompartmental stock market is linked to the upper outer wall along a first joint line that defines the waistline of the wall as an edge and where the second joint not overlapping or at least partially overlapping it is preferably below in the joint line which defines the waistline in the direction of the outer wall lower. The side wall as a border is also slightly collected or gathered in the final bag to provide an appearance mattress type.

Therefore, according to another aspect of the invention, a product for machine dishwashing is provided in form of a water-soluble bag comprising a plurality of compartments in generally superimposed relationship, containing each compartment one or more detergent active components, in where the bag has a first compartment comprising a liquid composition and a second compartment comprising a powder composition, where the weight ratio between the Liquid and solid composition is from 1:30 to 30: 1, where the bag comprises upper and lower outer walls generally opposite, a side wall as an edge and one or more walls of internal division, where at least one partition wall internal is fixed to an exterior wall higher or lower than along a first joint line and one or both of said walls exteriors and said partition wall are fixed to the wall lateral as an edge along a second joint line and where the joint lines are at least partially not overlapping

At least one of the plurality of Water-soluble bag compartments comprises a composition in powder or densified powder composition. Powder composition usually includes solid traditional materials used in the dishwashing detergent, as additives detergency builders, alkalinity sources, enzymes, whiteners, etc. The powder composition may be in the form of dry powder, hydrated powder, agglomerates, encapsulated materials, extrudates, pills or mixtures thereof. It is also useful to have water-soluble bags with several compartments comprising different powder compositions, usually compositions in different compartments comprising active substances or incompatible active substances that need to be released in different moments of the dishwashing process. Is advantageous to have bleach and enzymes in different compartments

In a preferred embodiment at least one of The powder compartments comprise bleach in the form of particles The bleach is preferably selected from inorganic peroxides including perborates and percarbonates, organic peracids including monoperoxy carboxylic acids premolded, such as phthaloyl amido peroxy hexanoic acid and diacil peroxides.

In the case of powder compositions you can obtain a differential solution, for example, varying the degree of powder compression and / or particle size of the compositions powder in the same or in different compartments. Another way to obtain the differential solution is to use films water-soluble of different thickness or percentage of solubility Different in conditions of use. The solubility of the film is you can control for example the pH, the temperature, the ionic strength or by any other means. In the processes in those who want to achieve phase or sequential release of the active detergent substances, it is preferred that each of the Bag compartments have a percentage of decay or dissolution profile different under conditions of use.

At least one of the plurality of Water-soluble bag compartments comprises a composition liquid Liquid compositions comprise liquid materials traditional used in detergents for washing the crockery, such as non-ionic surfactants or solvents organics described later herein. In preferred embodiments, the liquid composition comprises enzymes of detergency. Water-soluble bags here they have a compartment that comprises a liquid composition and another compartment comprising a solid composition. In the case of liquid compositions, especially liquid compositions included in a secondary package, it is desirable that the composition have a water content similar to the water content of the film in order to prevent water transfer between one and other. In cases where the water content is lower in the composition that in the film, water can migrate from the film to the composition making the water-soluble bag become fragile For similar reasons, it is also desirable to have a similar amount of plasticizer in the composition and in the movie.

In another embodiment, at least one of the plurality of compartments of the water-soluble bag comprises a composition in the form of a paste. The multi-compartment bags they can also include gel or wax compositions.

In preferred embodiments at least one of the plurality of compositions of the water-soluble bag comprises a Organic solvent system compatible with the water-soluble bag. The organic solvent system can simply act as a liquid carrier, but in preferred compositions, the solvent can help remove stains from cooked, baked or burned and therefore the detergent has functionality by itself same. The organic solvent system (comprising a single solvent compound or a mixture of solvent compounds) preferably has a volatile organic compound content greater than 1 mm Hg and more preferably greater than 0.1 mm Hg of less than 50%, preferably less than 20% and more preferably less than 10% by weight of the solvent system. At the moment memory the volatile organic compound content of the system solvent is defined as the content of organic components in the solvent system that has a vapor pressure greater than prescribed limit at 25ºC and atmospheric pressure.

The organic solvent system used in the present invention is preferably selected from solvents organic amine, including alkanolamines, alkylamines, alkylenamines and mixtures thereof; alcohol solvents including aromatic, aliphatic alcohols (preferably C 4 -C 10) and cycloaliphatic alcohols and mixtures thereof; glycols and glycol derivatives included C 2 -C 3 (poly) alkylene glycols, glycol ethers, glycol esters and mixtures thereof and mixtures selected from organoamine solvents, solvents alcoholics, glycols and derivatives of glycols. In one embodiment preferred the organic solvent comprises organic solvent of amine (especially alkanolamine) and glycol ether solvent, preferably in a weight ratio of about 3: 1 to about 1: 3 and in which the glycol ether solvent is select ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, propylene glycol monobutyl ether and mixtures thereof. Preferably, the glycol ether is a mixture of diethylene glycol monobutyl ether and propylene glycol butyl ether, especially in a 1: 2 to 2: 1 weight ratio.

A method is also provided for washing the crockery, cutlery and glassware in an automatic dishwasher using the automatic dishwasher product described in the present invention The method is suitable for release simultaneous or sequential detergent active substances in one or more prewash cycles, main wash or rinse cycles of the dishwasher, although it is especially suitable for release in the main wash or rinse cycles.

A process to manufacture the bags of the The present invention comprises the steps of: i) forming a first moving band of full bags and optionally seals mounted so that they can be separated on a first endless surface in motion (preferably in rotation; ii) conformation of a second moving band of full and optionally sealed bags mounted so that it can separate on a second endless surface in motion (preferably in rotation); iii) overlapping and sealing or fixing said first and second band in motion to form a superimposed and sealed band; and iv) the separation of said band superimposed and sealed in a plurality of bags Water soluble multicompartmentals. Preferably the second endless moving surface moves synchronously with said First endless surface in motion. This facilitates the realization of the process in a continuous way.

The first band of full open bags is You can close with any means for closing bands, as per example a film of material for forming bags, although in a preferred embodiment it is preferably closed with the second band of bags, which avoids the use of a layer or film extra. The means for closing the band preferably moves synchronously with the first endless surface and the first band of open bags mounted on it. Preferably the second band of bags is reversed before the close of the first band of open bags, preferring this from the point of view of facilitating the overlap in the sealing process of the band.

The first band in open stock movement it can be formed, for example, by incorporating a water-soluble film to a matrix that has a series of molds. The molds can have any suitable size and shape, being preferred for use in the present invention rectangular molds having a profile suitable to fit most dispensers of the dishwasher. Apart from having the advantage of adapting to dispenser, rectangular bags inherently have regions with a different film thickness and this can contribute to improve the dissolution profile of the bag.

Open bags can be shaped using thermoforming, for example, by heating the molds or applying heat by any other known method, such as blowing hot air or using heat lamps. If desired, Vacuum can be used to propel the film into the mold. Open bags can be formed alternately by vacuum formed, in which case, heat can be added to facilitate the process In general, thermoforming consists fundamentally in a process of plastic deformation while vacuum forming is fundamentally a deformation process elastic The two techniques can be combined to produce bags with any desired degree of elasticity / plasticity.

The first band of open bags is formed preferably on a first endless surface in rotation, this surface being in a preferably horizontal position or basically horizontal during the filling of the bag.

A preferred process comprises the steps of conformation and filling of a horizontal band or basically horizontal moving open bags mounted so that it they can separate on a first endless surface in motion and the closed band of open bags with a band on superimposed movement of preformed bags, filled and sealed that moves synchronously with that one. The first endless surface preferably moves in a motion horizontally or basically horizontal continuously and preferably in a continuous horizontal rectilinear movement during the stage of filling of the first moving band of open bags.

Preferably the first open band of open bags are filled by a filling station of product comprising means for filling quantities of one or more product feed streams in each of the open bags Preferably this filling station is arranged so that it moves synchronously with the first band of open bags during the filling stage, whereby, any acceleration / deceleration of open bags is avoided during filling and the subsequent pouring of detergent and contamination of the sealing area. Horizontal movement rectilinear of the first band of open bags allows filling total or more complete of the open bags with what is achieved Better use of the film. Alternatively, the filling station can be stationary.

The detergent product can be dispensed in each one of the bags opened by dosing devices individual or dispensing devices that have a single feeder or means to supply a single current of product feed, this being preferred in cases where a single premixed composition must be released in the bag. At case of multi-component liquid compositions, Each bag can be filled by multiple feeders or means to supply a plurality of supply currents of the product, providing each feeder a liquid composition different (or component thereof), so as to avoid Need for a premix stage. In the case of compositions Multi component powder, again each bag can be filled through multiple feeders, each of them supplying a powder composition (or component thereof) so that it They form different layers of product. In the case of compositions in dust, it is an advantage to have a screen strap that has a hole of the same size or slightly smaller than the open bag opening in order to avoid contamination of the board.

The first band of open bags can be optionally close and seal with a film after filling and before overlapping and sealing the second band of bags in motion. The second band of bags can be manufacture separately but in preferred embodiments the second band of bags is placed horizontally or substantially horizontally during the filling of the bags. In a preferred method the stage of filling the second band Horizontal moving open bags is done using a second filling station of the product that moves synchronously with the second endless surface. In a procedure, the filling station comprises means for release of a plurality of feed streams from product, as in the case of the filling station for the first band of open bags described above in the present memory When the first band itself is sealed with the film before superimposing the two bands, it may be required that the two bands are fixed together along a joint line discontinuous

Although each of the first and second endless surfaces and the corresponding band of bags can be adapt for a horizontal, rectilinear or curvilinear during the filling of the bags, herein a process in which the first endless surface is preferred it moves following a rectilinear horizontal movement during the filling stage of the first band of open bags in movement and where the second endless surface moves following a basically horizontal rectilinear movement or curvilinear during the filling stage of the second band in Open bag movement.

Preferably the second endless surface rotates in a direction opposite to that of the first surface without finish.

The second band bags are also covered, they close and seal preferably with a film type closure after filling and before overlapping on the first bag band and the sealing of the two bands. Preferred use in the present invention it is heat sealing, which can be perform by any known means, for example, by direct application, infrared, ultrasonic radiation, radiofrequency, laser. Solvent sealing can be used alternatively in the present invention.

The two-compartment bag band formed in this way it is then divided into individual bags, by example, by known cutting methods. Preferably, the Bags are produced at a constant rate at a constant speed, which can facilitate the automation of the packaging process. Although the procedure described above herein It refers to the manufacture of two-compartment bags, it They can manufacture multi-compartment bags with more than two compartments in a similar way, for example, overlapping and sealing three or more bands of bags. They are also very useful for use in the present invention multicompartmental bags in the which at least one of the compartments is horizontally divided into a plurality of compartments. Another process for Bag manufacturing includes:

to)

conformation and partial filling of a moving band of open bags mounted so that they can separate on an endless surface in motion, being the partial filling so that enough space is left for formation of a second compartment in the same mold;

b)

he closing and sealing of said moving band with a means of closure of the band that moves synchronously with it by the which means of closure of the band is introduced into the bags partially filled so that a plurality of closed and open compartments superimposed;

C)

filling, closing and sealing of open compartments superimposed by a second closure of the band that moves synchronously with said band in motion Y

d)

separation of said band in a plurality of water-soluble multicompartmental bags.

In the previous process the formation of bags multicompartmental requires only an endless surface in movement, which can be beneficial from the point of view of economic. Each bag is formed in a unique mold. After form the band of open bags, each open bag is filled partially, it is closed and sealed giving rise to a second open compartment, which is then filled, closed and seal. In a preferred embodiment the sealing steps are performed by sealing with solvent.

The term "filling" herein includes both "partial" and "complete" filling of a bag or compartment thereof. An open bag or compartment It is considered to have been completely filled when the product fill at least approximately 90% of the volume of the bag or open compartment. "Partial" filling is done correspondingly.

In a slightly modified version of this process, the sealing stage is performed at a later stage of process. The process includes the stages of:

to)

conformation and partial filling of a moving band of open bags mounted so that they can separate on an endless surface in motion;

b)

closed of said moving band with a means for closing the band that moves synchronously with said band by which the means for closing the band is enter partially filled bags so that it forms a plurality of closed and open compartments overlays;

C)

filling and closing of compartments open overlays by a second means for closing the band that moves synchronously with said band in movement;

d)

sealing of said band and said means for closing said first and second band and

and)

the separation of said band into a plurality of bags Water soluble multicompartmentals.

In a preferred embodiment of this process, the sealing stage is done by sealing ultrasonic.

In another variation of this method, the band of open bags of stage (a) is filled, partially or completely, with a first composition comprising a detergent or auxiliary active substance and then or the composition densifies or the bag enlarges to provide Enough space for the formation of the second compartment. In In the case of a powder composition, densification can be get by compaction, tapping, tamping, vibration, etc., densification being carried out preferably so that obtain an increase in bulk density of at least about 5%, preferably at least about 10% and especially at least about 20%, more preferably At least about 30%. The final apparent density is preferably at least about 0.6 g / cc, more preferably at least about 0.8 g / cc, more especially at least about 1 g / cc. The means to Enlarge the bag include means to alter the size or volume of the mold, for example, a section with a movable floor, a piece insertion of variable size or volume, etc.

In alternative embodiments, the compartments Open overlays can also be formed after the stage of closing and sealing the moving band of open bags, understanding the process of the stages of:

to)

forming and filling a band in movement of open bags that are mounted so that it they can separate on an endless surface;

b)

closing and sealing of said band in movement with a means for closing the band that moves synchronously with it so that a plurality is formed of closed compartments;

C)

conformation of a cavity within some or all of the closed compartments formed in the step (b) so that a plurality of compartments is generated open overlays above compartments closed

d)

filling, closing and sealing of open compartments superimposed by a second means to the closure of the band that moves synchronously with said band on the move and

and)

the separation of said band into a plurality of bags Water soluble multicompartmentals.

Again, in a slightly modified version of this process, the sealing stage is carried out in one stage after the process, the process comprising the stages of:

to)

forming and filling a band in open bag movement mounted so that you can separate on an endless surface in motion;

b)

closing of said moving band with a means for closing the band that moves synchronously with this so that a plurality of compartments is formed closed

C)

the conformation of a cavity within some or all of the closed compartments formed in step (b) so that generate a plurality of open compartments superimposed by above the closed compartments;

d)

filling and closing of compartments open overlays by a second means for closing the band that moves synchronously with said band in movement;

and)

sealing of said band and said first and second means for closing the band and

F)

the separation of said band into a plurality of bags Water soluble multicompartmentals.

In order to conform the cavities, the Closed compartments can undergo a compression stage or powder compaction as described above, and if it is necessary, means such as vent holes can be incorporated in the band to allow the air out of the compartments tablets

In all these aspects of the process, the endless surface preferably moves following a movement horizontal or basically horizontal continuous, preferably rectilinear, during the filling stages of the open bags and open compartments superimposed on the moving band. Alternatively, the movement may be intermittent, although It is less preferred. It is also preferred that the filling steps be perform using the filling station of the product that moves synchronously with the endless surface. Suitably the product filling station may comprise means for the filling quantities of a plurality of streams of product feed in each of said compartments.

Preferably, multi-compartment bags formed according to any of the procedures described in the The present invention comprises a plurality of compartments that they contain a powder composition and a plurality of compartments containing a liquid composition, in gel or in pasta shape It is also understood that through the use of suitable feeding stations, it is possible to manufacture bags multi-compartment incorporating various powder compositions different or distinctive and / or liquid compositions, in gel or in Different or distinctive pasta. This can be especially valuable. for the manufacture of unit dose forms that exhibit effects visual and / or other new sensory effects.

The bags of the present invention can provided in a package comprising an outer container as a translucent container, for example, a translucent container or bottle which contains a plurality of water-soluble bags or another dose units of detergent product in a multiplicity of groups visually distinctive or otherwise sensory. By visually distinctive here it is indicated that the Groups can be distinguished in terms of shape, color, size, pattern, ornament, etc. For the rest, the groups are distinctive in terms of providing an exclusive sensory signal such as odor, sound, touch, etc.

Preferably a container of detergent for washing translucent dishes, preferably transparent, in which the number of distinctive groups of bags or of other unit doses is at least 2, preferably as minimum of 3, more preferably at least 4 and especially at least 6 and in which the number of unit doses per container it is at least about 10, preferably at least about 16 and more preferably at least about 20. Preferably the unit doses are bags multi-compartment, each compartment being by itself visually or otherwise distinctively from the rest of the Compartments in an individual bag. Preferably, the groups of bags are distinctive in color. In the case of bags multicompartmental, at least one group of bags has a compartment that is visually distinctive, for example, in terms of to color, of the corresponding compartment in one or more of others groups of bags. Preferably in said embodiments, all Bag groups have at least one "common" compartment, that is, whose appearance is the same between groups. Preferably the visually distinctive compartment contains a liquid, a gel or a pasta; The common compartment contains a powder or a pill. The bags can be arranged in any form on the package, or either randomly or in an order, for example, suitable arrangements that include layers where each bag It comprises at least one compartment of a different color from that of any of the remaining compartments of the remaining bags on the same layer. The container can be made of plastic or any other material, provided that the material is what strong enough to protect the bags during transport. This type of packaging is also very useful because the User does not need to open the container to see how many bags are left, since the bags of different colors are very easy to Identify from the outside. Alternatively, the package can have a non-translucent outer container, perhaps with signs or illustrations that represent visually distinctive content of the container

In other packaging distinctive groups of bags They contain different perfumes. Perfumes can be perfumes associated with a color, for example, lemon-scented yellow, pink With the smell of strawberry, blue with the smell of the sea.

The processes described in the present invention for the manufacture of multicompartmental bags you can adapt to form a plurality of bags in a multiplicity of sensory distinctive groups as described above, whereby each of a multiplicity of compartmental groups It is filled with a sensory distinctive composition. This simplifies the manufacture of the container of the invention.

Detailed description of the invention

The procedure used herein invention for shaping the first and / or second band in movement implies the continuous feeding of a film water soluble on an endless surface, preferably on a horizontal or basically horizontal part of an endless surface, or otherwise, in a non-horizontal part of this surface, of so that it moves continuously towards and eventually on the horizontal or basically horizontal part of the surface. Naturally, materials in the form of a film and / or can be used different films of different thicknesses for the manufacture of the first and second bands in motion, where for example requires that the compartments have different characteristics of solubility or release.

In a preferred process for manufacturing of the first and second band in motion, a part of the endless surface will move continuously following a movement horizontal rectilinear, until it rotates around an axis perpendicular to the direction of movement, typically approximately 180 degrees and then it will move in the opposite direction, usually again following a movement horizontal rectilinear. Eventually, the surface will rotate again until reaching its initial position. In other procedures, the surface moves for example following a curvilinear movement, for example, circular, by which at least a part of the surface is basically horizontal for a period of time Simple but finite. When used, these procedures are mainly valuable for the production of the second band in movement.

The term "endless surface" in the This report indicates that the surface is endless in a dimension at least, preferably only in one dimension. By For example, the surface is preferably part of a belt rotary plate conveyor comprising molds, as Describe below in more detail.

The horizontal or basically horizontal part of the surface can have any width, depending on shape typical of the number of rows of molds across, the size of the molds and the size of the separation between the molds. When this provided that it works horizontally rectilinearly, the part Horizontal endless surface can have any length, typically depending on the number of stages of the procedure required to take place in this part of the surface (during continuous horizontal movement of the surface), the time required per stage and the optimum speed of the surface needed for these stages. Naturally when a higher or lower continuous speed is used throughout the process, it may be necessary for the surface length to be shorter or longer. For example, if several stages are performed in the horizontal part, the part has to be longer or the speed less than if for example there are only two stages in the part horizontal.

It may be preferred that the surface width is up to 1.5 meters or even up to 1.0 meters or preferably between 30 and 60 cm. It may be preferred that the part horizontal of the endless surface be from 2 to 20 meters, or even from 4 to 12 meters or even from 6 to 10 or even 9 meters.

The surface typically moves with a constant speed throughout the entire process, which can be carried out at a constant speed. May be preferred speeds between 1 and 80 m / min, or even 10 to 60 m / min or even from 2 to 50 m / min or even from 30 to 40 m / min.

The procedure is preferably performed in an endless surface that has a horizontal movement during a such time that allows the formation of the bag band, filling of the bags, superposition of the second moving band of the bags, sealed from the two bands in motion and cut to separate the overlapping bands in a plurality of bags multi-compartment Then the bags are removed from the surface and the surface will rotate around a perpendicular axis to the direction of movement, typically about 180 degrees, to move then in the opposite direction, of typical way, to turn after again, after which stage a) begins again.

Preferably, the surface is part of and / or preferably it is connected so that it can be overcome rotating belt in motion, for example, a belt conveyor or belt conveyor belt. Then, preferably, the surface can be removed or replaced with other surface that has other dimensions or that comprises molds in a different way or dimension. This allows the team to It can be easily cleaned and can also be used for Production of different types of bags. This may be for example a belt that has a series of plates, of which the number and size will depend on the length of the horizontal part and of the diameter of the surface rotation cycles, for example, which has 50 to 150 or even 60 to 120 or even 70 to 100 plates, for example, each of them having a length (direction of plate and surface movement) 5 to 150 cm preferably 10 to 100 cm or even 20 to 45 cm.

The plates form the surface without end or part of it and typically the molds are comprised on the surface of the plates, for example each plate it can have a number of molds, for example up to 20 molds in the width direction, or even 2 to 10 or even 3 to 8 and for example up to 15 or even 1 to 10 or even 2 to 6 or even 2 to 5 molds longitudinally, that is, in the direction of movement of the plates.

The surface, or typically the belt connected to the surface, it can move continuously using the use of any known method. The use of a system is preferred of zero elongation chain, which drives the surface of the tape connected to the surface.

If a plate conveyor belt is used, this preferably contains a) a main belt (preferably steel) and b) series of plates, which they comprise 1) a surface with molds, so that the plates of the endless surface with molds described above and 2) a connection with a vacuum conduit and 3) preferably a plate base between the plates and the connection with a vacuum duct. TO then the plates are preferably mounted on the main belt so that there is no air leak from the joints Between the plates The plate conveyor belt as a whole then moves preferably along (above; over below) of a static vacuum system (vacuum chamber).

It may be preferred that the surface be connected to 2 or more different vacuum systems, which can provide a different negative pressure and / or provide a negative pressure such in a greater or lesser period of time or during a longer or shorter duration. For example, it may be preferred that a first vacuum system provide a negative pressure so continue to the area between or along the molds / edges and that the other system only provides a vacuum for an amount determined time to stretch the film on the molds. By For example, the empty stretch of the film on the mold is You can apply only for 0.2 to 5 seconds or even 0.3 to 3 or even 2 seconds or even 0.5 to 1.5 seconds, once the film is on the horizontal part of the surface. This empty it may preferably be such that it provides a pressure negative between -10 kPa (-100 mbar) and -100 kPa (-1000 mbar), or even from -20 kPa (-200 mbar) to -60 kPa (-600 mbar).

It may be preferred, for example, to connect two or more vacuum systems or preferably duct pumps described above, so that each vacuum system is connected to each duct, preferably so that the systems are not interconnected in the duct, thus completely separating the vacuum systems with each other and to ensure release vacuum controlled to molds / surface between / along the mold / edges.

It is understood that therefore, all plates and the main belt move continuously, so typical with the same constant speed.

The surface, or plates described above, they are preferably made of a material resistant to corrosion, which is durable and easy to clean. May be preferred that the surface or plates, including mold areas are made of aluminum, preferably mixed with nickel or optionally only the outer layers comprising nickel and / or nickel and aluminum mixtures.

Preferably, at least the top layer between and / or in the surface molds is of a material resilient deformable, preferably at least the top layer Between the molds The material is typically such that has a coefficient of friction of 0.1 or more, preferably 0.3 or plus. For example, the top layer between the molds, although even In the molds, it can be rubber, silicone material or cork, preferably rubber or silicone rubber. It is also preferred that the material is not too hard, for example, similar to the cork of silicone that has a shore hardness value of 10 to 90.

The molds can have any shape, length, width and depth, depending on the dimensions required of the bags. By surface, if the molds are desired They can also vary in size and shape with each other. By For example, it may be preferred that the final volume of the bags be between 5 and 300 ml, or even 10 and 150 ml or even 20 and 100 ml or even up to 80 ml and therefore mold sizes fit adequately.

The incorporation of the film to, and of form typical inside or on top of the surface and preferably on the horizontal part of it is made of continuously and so typically with a constant speed at throughout the process This can be done by any method. known, preferably by using rollers from which the film is unwound. The film can be transported from the rollers to the surface by any means, by example, guided by a belt, preferably a belt resilient deformable, for example, a rubber strap or material silicone, including silicone rubber. The material is shaped typical such that it has a coefficient of friction of 0.1 or more, preferably 0.3 or more.

It may be preferred that the rollers rewind the film with a speed of at least 100 m / min, or even 120 at 700 m / min, or even 150 to 500 m / min, or even 250 to 400 m / min.

Once on the surface, the film can be hold in position, p. e.g., fixed or fixed on the surface by any means. For example, the film can be attached with jaws or clips on the edge of the surface, where not there are molds, or press them with rollers on the edges of the surface, where there are no molds, fasten them with a strap on the edges of the surface, where there are no molds.

To facilitate handling and positioning of the film, for greater accuracy and better reliability in alignment and in order not to lose too much of the surface of the film (i.e. placed on or on the jaws, clips, rollers or belt) and also in order to reduce tension on the film or ensure a more homogeneous tension on the film, it is preferred to keep the film in position by the application of vacuum on the film, stretching or pushing the film in fixed position on the surface. Typically this it is done by applying vacuum (or negative pressure) by the entire surface to be attached to the film, for example, under the movie. This method is also suitable even if the film width is larger than the surface, so that this system is more flexible than the use of jaws or clips.

Preferably, the vacuum is applied along the edges of the film and, thus, typically at the edges of the film and / or on the surface between or around the molds, of typical shape along the edges of the molds. It preferred apply the vacuum (at least) along the edges of the surface.

Preferably, said surface comprises holes that are connected to a device that can provide a vacuum, as is known in the art, or so called vacuum chamber (s). Thus, the surface has preferably holes along the surface edges and / or holes along or between the molds.

It is preferred that the holes be small, preferably with a diameter of 0.1 mm to 20 mm, or even 0.2 to 10 mm or even 0.5 to 7 or even 1 to 5 mm.

Preferably, at least some of the holes are near the edges of the mold, to reduce the wrinkle in the area around the edges of the mold, which in a preferred embodiment of the present invention it serves as closing or sealing area; preferably the distance between the edge of the mold and the edge of the first or closest hole is 0.25 to 20 mm from the edge of the mold, or even preferably 0.5 to 5 mm or even 1 to 2 mm.

It is preferred that the rows of holes are present along the edge of the surface and / or along the edges of the molds; it may be preferred that 2 or 2 are present 3 or more rows of holes.

The use of many small holes in the way described above guarantees a more homogeneous voltage of the film and this reduces the tension required to fix the film and this improves the fixation and reduces the possibility of the film It wrinkles.

The use of a vacuum system to fix the film in its position is especially beneficial when the film is subsequently stretched over the molds by application of empty as described below.

Open bags can be formed in the molds by any method and, as described Previously, preferred methods include the use of (as minimum) a vacuum or negative pressure system to stretch the film about the molds. Preferred methods (also) include the heating and / or wetting of the film and by which manufactures a more flexible film or even stretches so that adopts the shape of the mold; preferably, it is combined with application of a vacuum system on the film, which pushes the film in the molds, or combinations of all these methods

At least the present invention is preferred use empty In the case of bags comprising powders it is advantageous to perforate the film for several reasons: first, to reduce the possibility of defects in the film during formation of the bag, for example, defects in the movie that cause the movie to break if the movie stretches too quickly, secondly, allow the release of any gas derived from the product included in the bag, such as oxygen formed in the case of dusts that contain bleach, and thirdly, allow release Continued perfume. When heat and / or also used humidification, this can be used before, during or after use vacuum, preferably during or after application of the empty.

Thus, it is preferred that each mold comprises one or more holes which are connected to a system that can provide a vacuum through these holes on the film which is above the holes, as described with greater detail in the present report. It is preferred that the vacuum system be a vacuum chamber that comprises at least two units different, each separated into different compartments, as described herein.

Heat can be applied by various means, for example, directly, passing the movie under a heat element or through hot air, before introducing it on the surface or once on the surface or indirectly, for example, by heating the surface or applying an article heat on the film, for example, up to temperatures of 50 to 120 ° C, or even 60 to 90 ° C, preferably for example, with light infrared

The film can be moistened by any medium, for example, directly by spraying a wetting agent (includes water, film-shaped material solutions or plasticizers for the film-like material) on the film, before incorporating it on the surface or once on the surface, or indirectly by wetting the surface or by applying a hot article on the movie.

The filling of the first and second bands of Open bags can be made using any known method for filling items (movement). The exact method more preferred depends on the shape of the product and the speed of fill.

One method is for example a dosage by flood, whereby the band of open bags goes through a continuous horizontal or basically horizontal movement under a dosage unit, which is static and which has a device for dosing exactly an amount or volume of product per unit of time. The problem or disadvantage of this method may be that the product is dispensed over the areas between open bags, which typically serve as an area sealed; This can not only be a waste of product, but which also makes closing difficult. This problem is especially acute in the case of products in the form of mobile liquids. The Paste or gel products are easier to get with This form of filling procedure.

In general, preferred methods include continuous movement in filling the line, which uses a dispensing unit placed above the open bags, which has an endless rotary surface with nozzles, which moves in a rotational manner from typical form with a continuous movement, whereby the nozzles move with the same speed as the bags and in the same direction, so that each open bag is under the same nozzle or nozzles for the duration of the dispensing stage. After the filling stage, the nozzles rotate and return to the original position to begin another dispensing / filling stage. Each nozzle or several nozzles together are preferably connected to a device that can accurately control that only
an established quantity or volume of product is dispensed during one rotation per nozzle, thus, e.g. ex. in a bag.

It may be preferred that the system filling / dispensing is such that 10 to 100 cycles can be done (filling stages) per minute, or even 30 to 80 or even 40 at 70 per minute This will naturally be adjusted depending on the open bag size, surface speed, etc.

A very preferred method for filling the open bags suitable for surface movement following a horizontal rectilinear movement is a method of Filling reciprocal movement. This process preferably use a refillable moving filling station (change the direction of movement) and that is variable speed. The filling station typically has a series of nozzles, each of which moves with the same speed as the open bags (to be filled) and in the same direction during the period in which product has to be dispensed in the bags open. Then, typically when a bag is full, the nozzle or the nozzles that fill the bag stop your movement along the bag and return in the opposite direction, to stop again, so that it is placed above other bag (s) open that are left by fill and then start moving again in direction contrary, with the same speed and in the same direction as the open bags, until it reaches the speed of the bags for then continue with this speed and start dispensing and filling the bag (s), as in the previous filling cycle. The return movement speed may be higher than movement speed during filling.

Each nozzle or series of nozzles together is preferably connected to a device that can control exactly that only a set amount or volume of product is dispensed during one rotation per nozzle, e.g. eg well in a bag.

The unit or filling station in the process of the invention preferably uses a flow measuring device and / or a positive displacement pump to dose the adequate quantities or volumes of product per open bag, in concrete it has been seen that a positive displacement bag is very exact. In this way, the required amount of product volume is introduced into the pump and this is then introduced into the nozzles For example, if the system is such that you have to fill 60 bags per filling cycle, typically provided 60 nozzles, connected to 60 positive displacement pumps (one pump per nozzle, per bag), which are all connected to A general tank with product.

The pumps can be adjusted depending on the product to be dispensed For example, if the product is a liquid viscous, the pumps have to be more powerful and if it is a Fast filling, surface movement is required.

Other methods that can be used include the flow measurement, by using a magnetic flow meter o mass flow meter and filling / pressure flow measurement (which maintains constant pressure and control of filling time and therefore the volume).

It may also be preferred to use a system of filling by which, before filling, a second one is placed surface with openings, each of which has a surface area equal to or less than the surface of an open bag, above the band of open bags in continuous motion and which moves continuously in the direction of the bag band and with the speed of the band of open bags, so that each opening remains placed above an open bag during the filling stage and that the space between at least part of the molds are covered, said second being preferably surface an endless moving belt that can rotate.

Filling can be done through the openings on this surface or belt, so that the product You can only enter the open bags and not in the area between bags, which is covered. This is advantageous because the area between the open bags (between the molds), which serves in a way typical as a sealing area when the bags are closed, it remains Product-free, which guarantees a better or more joint easy.

Full open bags close at then which can be carried out by any method. Preferably, this is also done although in the position horizontal and in a constant continuous movement and preferably on the horizontal part of the endless surface described previously.

Preferred in the case of a second band of movement is that the closure is manufactured by feeding continuous of a second material or film, preferably film Water soluble on and above the band of open bags and at then preferably the sealing of the first film and of the second film together, typically in the area between the molds and, therefore, between the bags. It preferred incorporate the closure material on the open bags with the same speed and movement and in the same direction as the bags open.

In the case of the first moving band, prefers the closure material to be the second band of bags closed, full, closing being carried out, as described previously, that is, placing the band of the full bags closed on the open bags continuously, preferably with constant speed and movement in it address of the open bags and which are sealed later with the first movie. Alternatively, the first moving band can also be closed using a film or material as described above for the second band before superimposing and sealing the first and second Bag moving band. Such embodiments can be prefer in the case of a multi-liquid composition which contains products or when required to make bags in Side by side relationship, but superimposable.

The sealing can be manufactured by any method The sealing can be manufactured in a way discontinuous, for example, transporting the bag band to another sealing area and sealing equipment. However the sealing is preferably done continuously and preferably with constant speed while the band of Closed bags moves continuously and with constant speed and it can also be done preferably in a horizontal position, preferably also in said horizontal part of the surface.

Preferred methods include heat sealing, solvent and solvent welding or wet sealing. So, it may be preferred to treat only the area that will form the joint with heat or solvent Heat or solvent can be applied by any method, preferably in the closure material, preferably only in the areas that will form the joint.

It is preferred that when heat sealing is used, a roller with cavities the size of the part of the bag that is not enclosed by the mold and having a pattern of the bags, it roll (continuously) over the band bags, passing below the roller. Thus, the hot roller only enters contact with the sealing areas, specifically between the bags around the edges of the molds. Typically the sealing temperatures are 50 to 300 ° C, or even 80 to 200 ° C, depending naturally on the material in the form of a film. Also useful is a movable, returnable sealing device, which functions as the movable filling / dosing device, returnable, which puts the area between the molds in contact, around of the edges, for a certain time to form the joint and which then moves away from the sealing area to go back and start another sealing cycle. In the case of heat sealing, it is important that the sealing area of the second band with the first band does not overlap the sealing area of the first and / or second individual band of the bags.

If it is used sealed with solvent or wet, it may also be preferred to apply heat. Methods of sealed / wet or solvent welded include application selective solvent on the area between the molds or on the closure material, for example, spraying or printing on these areas and then applying pressure on these areas to form the board. For example, the rollers can be used and belts for sealing as described above (optionally also applying heat).

The bands of superimposed and sealed bags can then be cut with a cutting device, which cuts the bags together, into separate superimposed multi-compartment bags and which partially cuts the band so that multi-compartment bags are formed by a side-by-side arrangement. side though superimposed
ble.

The cut can be done by any known method It may also be preferred to make the cut in a manner continued, and preferably with constant speed and preferably in a horizontal position. However, the stage of cutting does not need to be done horizontally, nor continually. For example, the band of closed bags (sealed) can be transported to the cutting device, e.g. eg, to another surface, where the cutting device works. Although, for ease of processing it may be preferred to perform the cutting stage on the same surface as in the stages previous.

The cutting device can be for example a article or a hot article, by which in the latter case, this "burn" the film / sealing area. It may be preferred that be a roller with sharp utensils, such as a knife, with cavities of the size and pattern of the bags, which rolls on the bags, so that sharp utensils only touch the area to cut. Also when the bag band moves in one direction (e.g., continuously and / or horizontally, for example, even over an endless surface of the present invention) may be preferred use a static device that contacts the area between the bags along the direction of movement, to cut the bags in the direction of movement in a continuous way. TO then the cut between the bags along the direction of the width of the bag band can be done by a stage intermittent cutting, for example, by applying a device cut for a short period of time over the area, separating the cutting device and repeating this action with the following group of bags.

The bag, when used herein it can be of any form and material that is suitable for contain the product before use, e.g. eg, without allowing release of bag compositions before putting on Contact the bagged composition with water. The exact realization it will depend for example on the type and quantity of the compositions in the bag, the required characteristics of the bag to maintain, protect and dispense or release the compositions, the number of compartments in the bag.

During the manufacture of the liquid compartment an air bubble is typically formed. This air bubble can reduce the understandability of the bag and therefore the Easy closure of the dispenser after placing the bag inside. It has been found that the ease of closure increases when the relationship between the diameter of the air bubble and the dimension Maximum side of the bag profile is approximately 1: 5 a approximately 1: 2. Preferably, the bubble has a diameter from about 9 to about 16 mm. The dimension of the Bubble can be controlled by process parameters.

When used, the water-soluble bag is placed usually inside the dishwasher dispenser and released during the main cycle of the dishwashing process. Without However, some dishwasher dispensers are not completely water tight, mainly for two reasons, or The dispenser has some openings that allow the entry of water or the dispenser is sealed with a rubber band that may deform over time due to the high temperature of the dishwashing process. The entry of water in the dispenser may cause premature leakage of part of the contents of the bag, which is lost at the end of the prewash. This problem It is especially acute in the case of bags comprising liquid compositions that have a low viscosity where you can lose a considerable amount of the product before the cycle Main wash The problem can be solved by making the bag or at least the liquid compartment thereof is of a film-shaped material that is designed to survive prewash cycle and release the contents of the bag on or after of the start of the main wash cycle. In the dishwasher Europeans, prewashing is usually done in a water cycle cold (approximately 20 ° C or less) without detergent and with a Duration of approximately 10 to 15 min.

Preferably the film-shaped material it has a water solubility according to the test defined below in the present invention of less than about 50%, more preferably less than about 20% and especially less of approximately 5% in cold water conditions (20ºC or less) when exposed to water for at least 10 minutes, preferably at least 15 minutes and a water solubility of at least about 50%, more preferably at least about 75% and especially at least about 95% in hot water conditions (30 ° C or higher, preferably 40 ° C or higher) when exposed to water for approximately 5 minutes and preferably when exposed to water for approximately 3 minutes Such materials in the form of a film referred to herein are basically water insoluble cold although soluble in hot water. Sometimes this is abbreviated simply as "hot water soluble."

50 grams ± 0.1 grams of material are added bag-shaped in a heavy 400 ml beaker previously and 245 ml ± 1 ml of distilled water. This one stays at the desired temperature, by using a water bath and vigorously stirring on a magnetic stirrer set to 600 rpm, for the desired time. Then the mixture is filtered. through a qualitative sintered glass filter folded with a maximum pore size of 20 µm. Water is removed from filtrate collected by any conventional method and is determine the weight of the remaining material (which is the fraction dissolved or dispersed). Then you can calculate the% of solubility or dispersibility.

Commercial films insoluble in cold water and soluble in hot water include BP26 marketed by Aicello, L10 and L15 marketed by Aquafilm, VF-M and VM-S marketed by Kuraray and E-2060 marketed by Monosol.

In a preferred embodiment a bag multicompartmental comprises a first compartment comprising a liquid composition and a second compartment comprising a powder composition or densified powder composition. He Liquid compartment is made of a water-soluble material hot as described above and the powder compartment or densified powder compartment is made of a cold water-soluble material, that is, a material that is soluble to a certain degree of at least 50%, preferably at least 75%, more preferably at least 95% by weight in cold water conditions (20ºC or less) when exposed to water for 5 minutes and preferably when exposed to water for 3 minutes. Due to the way in which dishwashers work Europeans (these are filled with cold water and cold water is heated by a heater), the compartment made of material Water soluble needs more time to dissolve than the compartment made of a water-soluble material. This form of bag allows a delayed release of the liquid composition providing the optimized use of the detergent composition. Preferably, the liquid composition comprises enzyme of detergency, this being advantageous from the point of view of stability during storage of the enzyme, separating the enzyme of bleach and highly alkaline materials contained in the powder or densified powder composition. Further, the compartment that contains liquid (basically insoluble in water cold and soluble in hot water) you will need more time to dissolve or disintegrate that the compartment containing the solid (cold water soluble), minimizing negative interaction in the wash solution between bleach and enzymes and between the surfactant and enzymes and providing better elimination of Protein stains and pre-treatment benefits in the stages after the dishwashing process.

The compartments of the bags containing solid compositions, in particular compositions comprising bleaching oxygen releasing, are usually perforated with in order to allow the spill of any oxygen formed. Without However, holes formed by drilling can also allow the spillage of perfumes or the exit of bad smells. By For example, surfactants often have a smell unpleasant associated and when said bags are packaged within a secondary container, the smell of unpleasant surfactant can be concentrate on the head space of the container and free each time The user opens the container. This problem can be avoided. including the surfactant in the liquid composition, since the compartments that contain the liquid must be free of drilled holes Thus, according to another embodiment, the composition Liquid comprises a surfactant. Another advantage of having the surfactant in the liquid phase is to avoid problems loading the surfactant on the solid material. Another advantage is that the surfactant is released with a certain delay with respect to the solid composition, allowing better performance of the Whitening and enzymes, which can be seen adversely affected by the interaction between the surfactant and the surfaces of crockery, cutlery and glassware.

Preferably the perfume is introduced into the solid composition, piercing and allowing the release of perfume before using the product in the dishwasher.

The films basically insoluble in cold water and soluble in hot water have a moisture and content of relatively low plasticizer, so the film would require an important time and temperature in order to seal them by heat sealing. These requirements may cause damage to the film, so that for example the holes drilled in the point where the film is stretched over the mold can cause a spill, especially problematic in the case of bags They contain liquid. Therefore, it is preferred that the compartments made of basically water insoluble films cold and soluble in hot water and housing liquids seal using solvent, which partially hydrates the film before sealing, reducing time and temperature required for sealing, generating solid joints and avoiding hole formation. In the preferred embodiment of bags with differential solubility that have a compartment that comprises a liquid composition and another compartment comprising a powder composition in which the liquid compartment is made of material basically insoluble in cold water and soluble in water hot and the powder compartment is made of material that is soluble in cold water, it is preferred that the liquid compartment be seal by solvent sealing while the liquid compartment is sealed with the powder compartment by heat sealing.

The bag can also be placed outside the dispenser, for example, in the cutlery basket, in a net or dishwasher door. In this case, it is preferred that The entire bag is made of a film-shaped material, such as for example, the one described above herein, which protects the contents of the bag until at least the beginning of the main wash cycle

Although the nature of bagged products It is such that they dissolve or disperse easily in water, you can prefer that disintegrating agents as effervescent sources, water swellable polymers or clays are present in the own bag, and / or in the product thereof, in particular sources effervescent based on an acid source and a carbonate. Acids Suitable include organic carboxylic acids such as acid fumaric, maleic acid, malic acid, citric acid; sources of Suitable carbonate include sodium carbonate salts, bicarbonate and percarbonate. Preferred levels of the adjuvants of the disintegration or sources of effervescence or both are 0.05% at 15% or even 0.2% to 10% or even 0.3 to 5% by weight of the total bagged composition.
