Description

DOSING CARTRIDGE FOR A WATER LEADING HOUSEHOLD UNIT

The present invention relates to a cartridge for use in water-bearing

Household appliances, comprising at least one enzyme-containing preparation.

State of the art

Dishwashing detergents are available to the consumer in a variety of forms. In addition to the traditional liquid hand dishwashing detergents have with the spread of household dishwashers in particular the machine

Dishwashing a great importance. These automatic dishwashing agents are typically offered to the consumer in solid form, for example as powders or as tablets, but increasingly also in liquid form. For some time now, the main focus has been on the convenient dosing of detergents and cleaning agents and the simplification of the steps necessary to carry out a washing or cleaning process.

Furthermore, one of the main objectives of the manufacturer of mechanical cleaning agents is the

Improving the cleaning performance of these agents, with a recent focus on the cleaning performance of low-temperature cleaning operations or in cleaning cycles with reduced water consumption is placed. For this purpose, the cleaning agents were preferably added to new ingredients, for example, more effective surfactants, polymers, enzymes or bleach. However, since new ingredients are available only to a limited extent and the amount of ingredients used for each cleaning cycle can not be increased to any extent for ecological and economic reasons, this approach has natural limits.

In this context, in particular devices for the

Multiple dosing of detergents and cleaning agents into the field of vision of product developers. In these devices, it is possible to distinguish between dosing chambers integrated in the dishwasher or textile washing machine on the one hand and independent devices which are independent of the dishwasher or textile washing machine on the other hand. By means of these devices, which contain the multiple of the amount of detergent necessary for carrying out a cleaning process, portions of washing or cleaning agents are metered into the interior of the cleaning machine in an automatic or semi-automatic manner in the course of several successive cleaning processes. For the consumer eliminates the need for manual Dosage at every cleaning or washing cycle. Examples of such devices are described in European patent application EP 1 759 624 A2 (Reckitt Benckiser) or in German patent application DE 53 5005 062 479 A1 (BSH Bosch and Siemens

Hausgeräte GmbH).

A significant problem in the introduction of such dosing devices in the interior of dishwashers or washing machines is the thermal instability of heat-sensitive to be metered preparation ingredients. Since in the described dosing washing and / or cleaning preparations for a plurality of washing or cleaning cycles remain in the water-bearing household appliance, especially in enzyme proteins whose activity at temperatures in dishwashing and washing machines from 70 ° C to almost 100 ° C. reduce significantly.

Cartridges for dosing devices of the type described above are known from the prior art, which protect heat-sensitive ingredients by insulating measures on the cartridge. For example, WO2008034697A1 discloses a multi-chamber cartridge which can be coupled to the door of a dishwasher, wherein the cartridge has thermal insulation at least in sections for heat-sensitive

Protect ingredients from too much heat from the inside of the dishwasher.

A disadvantage of such insulation solutions is that an effective insulation significantly increases the size of a cartridge, as well as cost Herst II, depending on the choice of

Insulation material increases considerably. Furthermore, the insulating material must be able to withstand the temperature cycling and humidity conditions prevailing inside a dishwasher, for example.

Object of the invention

The object of the invention is therefore to provide a cartridge which is inexpensive and easy to manufacture and in which heat-sensitive preparations, in particular enzymes, are to be stored substantially stably inside a water-conducting domestic appliance.

This object is achieved by a cartridge which is particularly suitable for use in

water-containing household appliances, comprising an enzyme-containing preparation which contains at least 0.8 wt .-% of at least one enzyme protein, preferably at least 1 .2 wt .-% of at least one enzyme protein and a specific heat capacity c _p at 20 ° C less than 3.8 J / (g ^* K), preferably less than 3.0 J / (g ^* K), and which is stored in a cartridge with a filling volume between 20 and 500 ml and an average wall thickness between 0.1 and 2 mm and the cartridge material one specific heat capacity c _p at 20 ° C between 1 and 2 J / (g ^* K), preferably between 1, 15 and 1, 9 J / (g ^* K), particularly preferably between 1, 5 and 1, 8 J / ( g ^* K).

Contrary to the opinion of the prior art, to isolate a cartridge as effectively as possible, it has now surprisingly been found that the

heat-sensitive enzymes also have their activity inside a water-bearing enzyme

Household appliance essentially maintained when the cartridge and the

heat-sensitive enzyme preparation have a low specific heat capacity, so can heat up quickly and cool.

The invention thus has the advantage to dispense with costly and structurally complex isolation measures and yet to ensure a sufficiently good thermal stability of particular enzyme proteins.

In a preferred embodiment of the invention, one or more enzyme protein (s) are selected from the group of amylases, proteases, cellulases, mannanase,

Accordingly, an embodiment in which the cartridge has at least two, in particular three to four, chambers is particularly preferred, wherein different preparations are stored in the chambers and at least one chamber contains an enzyme protein which has at least one contact surface with an adjacent chamber which has no Contains enzyme protein, wherein

the enzyme-containing preparation at least 0.8 wt .-% of at least one

Heat capacity c _p at 20 ° C between 1 and 2 J / (g ^* K), preferably between 1, 15 and 1, 9 J / (g ^* K), particularly preferably between 1, 5 and 1, 8 J / (g ^* K); and the further chamber / contains no enzyme protein, a specific heat capacity cp at 20 ° C between 1 and 2 J / (g ^* K), wherein the further cartridge chamber or at least one of the further cartridge chambers has a filling volume above the filling volume of the chamber with the enzyme protein; and

In an advantageous further development of the invention, the cartridge is essentially dish-shaped. The cartridge advantageously has a ratio of depth (T) of the cartridge to width (B) of the cartridge approximately at least 1: 5, preferably at least 1:10, particularly preferably at least 1:20.

It is further preferred that the chambers of the cartridge are arranged substantially side by side. In this case, it is preferable for the chambers to be arranged along a straight line. It is further preferred here that the width (B) of the chambers is in each case greater than the depth (T) of the chambers.

To make the level visible to the user, it is advantageous if the cartridge is formed - at least in sections - from a substantially transparent plastic. It has been shown that the transparency of the cartridge has a positive influence on the thermal stability of the ingredients.

Furthermore, it has been found that the transparency of the preparation has a positive influence on the thermal stability of the ingredients, so that it is preferable that the preparations stored in the cartridge are substantially transparent.

To avoid incorrect operation of the cartridge, it is advantageous that the cartridge is asymmetrical in the manner that the cartridge can be coupled only in a predefined position with a corresponding metering device. The cartridge according to the invention may in particular be configured for use in a dishwasher, tumble dryer and / or a washing machine.

cartridge

For the purposes of this application, a cartridge is understood to mean a packaging material which is suitable for enveloping or holding together at least one flowable, free-flowing or dispersible preparation and which can be coupled to a metering device for dispensing at least one preparation.

In the simplest, conceivable embodiment, the cartridge has a preferably rigid chamber for storing a preparation. In particular, a cartridge can also comprise a plurality of chambers which can be filled with mutually different compositions.

It is advantageous that the cartridge has at least one outlet opening, which is arranged such that a gravity-induced release of preparation from the cartridge in the position of use of the dosing device can be effected. As a result, no further funding for the release of preparation from the cartridge is required, whereby the structure of the metering device can be kept simple and the manufacturing cost low. Furthermore, the use of conveying means, such as e.g. Pumps omitted, whereby the life of a battery or batteries of the dosing device can be increased.

In a preferred embodiment of the invention, at least one second chamber is provided for receiving at least one second flowable preparation, the second chamber having at least one outlet opening arranged such that a gravity-induced product release from the second chamber in the use position of the dosing is feasible. The arrangement of a second chamber is particularly advantageous if in the separate chambers of the cartridge preparations are stored, which are usually not stable to each other, such as bleaching agents and enzymes.

Furthermore, it is conceivable that more than two, in particular three to four chambers are provided in or on a cartridge. In particular, one of the chambers can be designed for the delivery of volatile preparations, such as a fragrance to the environment.

In a further embodiment of the invention, the cartridge is integrally formed. In this way, the cartridges, in particular by suitable blow molding, cost-effectively trained in a manufacturing step. The chambers of a cartridge can be separated from one another, for example, by webs or material bridges which are formed during or after the blow molding process. The cartridge can also be formed in several pieces by injection molded and then assembled components.

Further, it is conceivable that the cartridge is formed in such a multi-piece, that at least one chamber, preferably all chambers, can be removed individually from the metering device or inserted into the metering device. This makes it possible, with a different consumption of a preparation from a chamber to exchange an already empty chamber, while the rest, which may still be filled with preparation, remain in the metering device. Thus, a targeted and needs-based refilling the individual chambers or their preparations can be achieved. In addition, it is conceivable to form the individual chambers in the form that the chambers can be coupled to one another or to the dosing device in only one specific position or position, thereby avoiding a user having a chamber in a position not intended for this purpose connects to the dosing device. For this purpose, the chamber walls can in particular be shaped such that they can be positively connected to one another. In the case of a cartridge formed from at least three chambers, the cartridges are shaped in such a way that the chambers can be positively connected to one another only in a specific defined position.

The chambers of a cartridge can be fixed to one another by suitable connection methods, so that a container unit is formed. The chambers can be fixed by a suitable form-fitting, non-positive or cohesive connection releasably or permanently against each other. In particular, the fixation can be achieved by one or more of the connection types from the group of snap-in connections,

Velcro connections, press connections, fusible links, adhesive bonds,

Welded joints, solder joints, screw joints, wedge joints,

Clamping or bouncing done. In particular, the fixation can also be formed by a shrink sleeve (so-called sleeve), which is pulled in a heated state over the entire or sections of the cartridge and firmly encloses the chambers or the cartridge in the cooled state.

To provide advantageous residual emptying characteristics of the chambers, the bottom of the chambers may be funnel-shaped inclined towards the discharge opening. Furthermore, the inner wall of a chamber can be formed by suitable choice of material and / or surface design in such a way that a low material adhesion of the preparation to the inner chamber wall is realized. Also by this measure can be the

Continue to optimize the residual emptying of a chamber.

In particular, the cartridge may also be asymmetrical. It is particularly preferred to form the asymmetry of the cartridge such that the cartridge is only in one predefined position can be coupled with the dosing device, whereby an otherwise possible incorrect operation is prevented by the user.

In or on a chamber, a metering chamber may be formed in a gravity-induced flow direction of the preparation in front of the outlet opening of a chamber. Through the metering chamber, the preparation amount that is to be released in the release of preparation from the chamber to the environment, set. This is particularly advantageous if the closure element of the dosing device, which causes the preparation output from a chamber to the environment, can only be put into a dispensing and a closure state without measuring or controlling the dispensing quantity. It is then ensured by the metering chamber that a predefined amount of preparation is released without an immediate feedback of the currently discharged, outflowing preparation amount.

The metering chambers can be formed in one piece or in several pieces. Furthermore, it is possible to firmly connect the metering chambers with the cartridge or detachably. In a dosing chamber detachably connected to the cartridge, it is possible in a simple manner to connect or exchange dosing chambers with different dosing volumes with a cartridge, whereby a simple adaptation of the dosing volumes to the preparation stored in each chamber and thus a simple assembly the cartridge for different preparations and their dosage is possible.

According to a further advantageous development of the invention, one or more chambers in addition to a, preferably bottom-side outlet opening each have a liquid-tight sealable, preferably head-side second chamber opening. Through this chamber opening, it is possible, for example, to refill stored in this chamber preparation.

For ventilation of the cartridge chambers ventilation options can be provided in particular in the head region of the cartridge to a pressure equalization in falling

Filling level of the chambers between the interior of the cartridge chambers and the

To ensure environment. These ventilation options can be designed, for example, as a valve, in particular silicone valve, micro-openings in a chamber or cartridge wall or the like.

If, according to another embodiment, the cartridge chambers are not ventilated directly but are provided via the metering device or no ventilation, for example when using flexible containers such as bags, this has the advantage that at elevated temperatures during a dishwashing cycle of a dishwasher by the heating of the chamber contents, a pressure is built up, which is to be dosed Presses preparations in the direction of the outlet openings, so that in this way a good emptying of the cartridge can be achieved. Furthermore, there is no risk of oxidation of substances of the preparation in such an air-free packaging, which is a bag or bag-in-bottle packaging in particular for

oxidation-sensitive preparations appear appropriate.

Preferably, the volume ratio formed from the overall volume of the metering device and the filling volume of the cartridge <1, more preferably <0, 1, particularly preferably <0.05. This ensures that, for a given total construction volume of metering device and cartridge, the overwhelming portion of the construction volume is taken up by the cartridge and the preparation contained therein.

The cartridge can take on any spatial form. It can for example be cube-shaped, spherical or plate-like.

The cartridge and the dosing device can in particular be configured with respect to their spatial form such that they ensure the least possible loss of useful volume, in particular in a dishwasher.

To use the dispenser in dishwashers, it is particularly advantageous to mold the device based on dishes to be cleaned in dishwashers. So this example, plate-shaped, be formed in approximately the dimensions of a plate. As a result, the metering device can save space, e.g. be positioned in the lower basket of the dishwasher. Furthermore, the correct positioning of the dosing unit opens up to the user intuitively through the plate-like shape.

Preferably, the metering device and the cartridge in the mutually coupled state, a ratio of height: width: depth between 5: 5: 1 and 50:50: 1, particularly preferably from about 10:10: 1. Due to the "slim" design of the dosing device and the cartridge, it is in particular possible to position the device in the lower cutlery basket of a dishwashing machine in the receptacles provided for plates This has the advantage that the preparations discharged from the dosing device pass directly into the wash liquor and can not adhere to other items to be washed.

Usually, commercial household dishwashers are designed in such a way that the arrangement of larger items to be washed, such as pans or large plates, is provided in the lower basket of the dishwasher. In order to avoid a non-optimal positioning of the metering system consisting of the metering device and the coupled with the metering cartridge by the user in the upper basket, in an advantageous embodiment of the invention, the metering system is dimensioned such that a positioning the metering system is only in the designated receptacles of the lower basket allows. For this purpose, the width and the height of the metering system can be selected in particular between 150 mm and 300 mm, particularly preferably between 175 mm and 250 mm.

Another advantage of a dish-shaped, flat design of the cartridge is the fact that the stored liquids by a relatively large surface-to-volume ratio, heat up quickly and cool again.

However, it is also conceivable to form the metering unit and / or the cartridge in cup form or cup shape with a substantially circular or square base.

The outlet openings of a cartridge are preferably arranged in a line, whereby a slender, plate-shaped design of the dosing device is made possible.

In a cup-shaped or cup-shaped design of the cartridge or its cup-shaped or cup-shaped grouping, however, it may also be advantageous to arrange the discharge openings of the cartridge, for example in a circular arc.

To provide an immediate optical level control, it is advantageous to form the cartridge at least in sections of a transparent material.

The cartridge is formed in particular dimensionally stable. However, it is also conceivable to design the cartridge as a flexible packaging such as a tube. Furthermore, it is also possible to use flexible containers such as bags, in particular if they are inserted into a substantially dimensionally stable receptacle in accordance with the bag-in-bottle principle described dimensionally stable cartridge designs - the need to provide a ventilation system for pressure equalization.

To preclude misuse of the cartridge, the cartridges may also have structural elements that interact with corresponding elements of the metering device according to the key-lock principle, so that, for example, only

Cartridges of a certain type can be coupled to the dosing device. Furthermore, this configuration makes it possible for information about the cartridge coupled to the dosing device to be transmitted to the control unit of the dosing device, as a result of which control of the dosing device coordinated with the contents of the corresponding container can take place. The cartridge is designed in particular for receiving flowable detergents or cleaning agents. Particularly preferably, such a cartridge has a plurality of

Chambers for spatially separated recording each different

Preparations of a detergent or cleaner on. Exemplary - but not exhaustive - are listed below some possible combinations of filling the chambers with different preparations:

It is particularly preferred that all preparations are free-flowing, as this results in e.g. a rapid dissolution of the preparations is ensured in the washing liquor of the dishwasher, whereby these preparations achieve a rapid to immediate cleaning or rinse effect.

The cartridge usually has a total filling volume of <5,000 ml, in particular <1,000 ml, preferably <500 ml, more preferably <250 ml, most preferably <50 ml.

It is preferred that the enzyme chamber of the cartridge has a filling volume between 20 and 500 ml

The chambers of a cartridge may have the same or different filling volumes. For a dual chamber configuration, the ratio is

Chamber volumes preferably 5: 1, in a configuration with three chambers, preferably 4: 1: 1, these configurations are particularly suitable for use in dishwashers.

As mentioned above, the cartridge preferably has three chambers. For the use of such a cartridge in a dishwasher, it is particularly preferred that one chamber contains an alkaline cleaning preparation, another chamber an enzymatic preparation and a third chamber a rinse aid, wherein the

Volume ratio of the chambers in about 4: 1: 1.

The chamber containing the alkaline cleaning preparation preferably has the largest filling volume of the existing chambers. Preferably, the chambers, which store an enzymatic preparation or a rinse aid, have approximately equal filling volumes.

In a two- and / or three-chamber design of the cartridge is in particular possible to stockpile in particular a perfume, disinfectant and / or Vorbehandlungszubereitung in a detachably arranged on the cartridge or the dosing, another chamber.

The cartridge comprises a cartridge bottom, which in the position of use in

Direction of gravity is directed downward and at the preferred for each chamber at least one arranged in the direction of gravity bottom outlet opening is provided. The outlet openings arranged on the bottom side are in particular designed such that at least one, preferably all, outlet openings can communicate with the inlet openings of the dosing device, ie preparation via the outlet openings from the cartridge into the dosing device, preferably gravitationally effected, can flow in.

It is also conceivable that one or more chambers have a not arranged in the direction of gravity bottom outlet opening. This is particularly advantageous if, for example, a fragrance is to be delivered to the environment of the cartridge.

The cartridge is preferably formed from at least two elements connected to one another in a material-locking manner, wherein the connecting edge of the elements on the cartridge bottom extends outside the outlet openings, that is to say the connecting edge does not intersect the outlet openings. This is particularly advantageous because it prevents leakage problems in the coupling with the metering device in the region of the outlet openings, which in particular in the case of the usually occurring in a dishwasher high

Thermal cycling occur.

The cohesive connection can be produced for example by gluing, welding, soldering, pressing or vulcanization. It is particularly preferable to connect the cartridge elements to one another by means of mirror welding. In the case of mirror welding, the boundary surfaces are heated by means of a metallic heating mirror, which contains the contour which brings the interfaces into contact, and shortly put into the plastic state, so that after removal of the heating mirror and joining of the parts, these plastic areas solidify again as a melt and solidify Connection result.

In addition to the known from the prior art mirror welding technique, individually molded parts, for example, can also be connected to each other by means of laser welding. In laser welding, one of the two materials must be at the interface

should be melted to wear a Absorbenz to the energy content of

Laser beam absorb and convert into heat, which then causes the melting of the corresponding material area. This is typically accomplished with color pigments that thermally interact with the laser beam conducted into the material. These interfaces to be joined may also be obscured if the in

Beam direction of the laser beam in front material is transparent to the laser beam and has no absorption property.

Furthermore, it is possible to connect individual cartridge elements by means of ultrasonic welding or IR welding via electrodes.

It is advantageous that the connecting edge extends along the top, bottom and side surfaces of the cartridge. This allows two cartridge elements in particular in

Injection molding process can be produced, wherein either both elements are trough-shaped or an element trough-shaped and the second element is lid-like.

To form a two-chamber or multi-chamber cartridge, at least one of the two cartridge elements can comprise at least one separating web which, in the assembled state of the elements, separates two adjacent chambers of the cartridge from one another.

Alternatively to the formation of the cartridge by two cup-shaped cartridge elements, it is also conceivable that a cartridge element as a cup-shaped container with at least one chamber and the second element of the cartridge bottom or -köpf, which is liquid-tight manner connected to the cup-like container along the connecting edge.

Of course, it is also conceivable to combine the above-mentioned cartridge configurations in any suitable manner. For example, it is possible a two-chamber cartridge of a trough-shaped and a lid-like

To form cartridge element and to arrange a third one-piece or multi-piece chamber on the head or lateral surface of the cartridge thus formed. In particular, such a further chamber for accommodating a preparation may be arranged on the cartridge and be configured in such a way that a release of volatile substances such as, for example, fragrances from the preparation into the environment of the chamber is effected.

According to a preferred embodiment, the outlet openings of the cartridge are closed by closure means at least in the filled, unopened state of the cartridge. The closure means may be designed such that they allow a single opening of the outlet opening by destruction of the closure means. Such closure means are, for example, sealing foils or caps.

According to a preferred embodiment of the invention, the outlet openings are each provided with a closure which allows in the coupled state with a dispenser outflow of preparation from the respective chambers and in the uncoupled state of the cartridge substantially prevents leakage of preparation.

In particular, such a closure is designed as a slotted silicone valve.

Furthermore, it is preferred that the ventilation openings of the cartridge are closed with a closure element before a first coupling with the dosing device. The

In particular, the closure element may be a stopper or a cap which, when it is first coupled to the dosing device, is opened, for example punctured, by the coupling process.

It is particularly preferred that prior to a first pairing of the cartridge with the dispenser all Au slassöff openings of the cartridge with a slotted silicone valve and all ventilation openings are closed with a cap.

The cartridge elements forming the cartridge are preferably formed from a plastic and can be formed in a common injection molding process, it may be advantageous to form a hinge acting as a connecting web between the two elements, so that after molding the two elements abut each other by folding and cohesively connected along the connecting edge.

In a further embodiment of the invention, an energy source, in particular a battery or accumulator, is arranged on or in the cartridge, preferably on or in the bottom of the cartridge. Furthermore, means for electrically coupling the energy source with the dosing device can be provided on the cartridge.

In a further preferred embodiment of the invention, the cartridge for coupling with a positionable within a household appliance dosing device for dispensing at least one washing and / or cleaning agent preparation, at least one chamber for storing at least one free-flowing or pourable washing and / or

Detergent preparation on, wherein the cartridge is coupled in the coupled state with the dosing device before entering rinse water in the chamber (s) and the cartridge at least one bottom in the direction of gravity discharge opening for - in particular gravitational - release of preparation of at least one chamber and at least one in the direction of gravity bottom-side ventilation opening for ventilation of at least one chamber, wherein the ventilation opening is separated from the discharge opening and the ventilation opening communicating with at least one chamber of the cartridge is connected.

It is particularly preferred that the cartridge comprises at least two chambers, very particularly preferably at least three chambers. In this case, it is advantageous that one ventilation opening and one discharge opening are provided for each chamber.

It is further preferred that the bottom-side ventilation opening is communicatively connected to a ventilation duct whose end facing away from the ventilation opening in the dispensing position of the cartridge coupled to the dosing device opens above the maximum fill level of the cartridge.

In this context, it is advantageous that the ventilation duct is completely or partially formed in or on the walls and / or webs of the cartridge. In particular, the ventilation channel can be integrally formed in or on the walls and / or webs of the cartridge.

For this purpose, the ventilation duct can advantageously be formed by joining at least two elements forming the cartridge. For example, a ventilation duct may be formed by joining a separating web of the cartridge formed in the shell-shaped element with two webs which surround the separating web and are arranged on the cartridge element.

In this case, it is advantageous if the ventilation channel is formed by integral joining, in particular by welding, of a separating web of the cartridge formed in the shell-shaped element with two webs which surround the separating web and are arranged on the cartridge element.

Alternatively, the ventilation duct, for example, as so-called. Be formed dip-tube. In order to ensure the ventilation of the cartridge in an inclined position, for example when the metering device is placed in the disc holder, it is advantageous that the level level (F) of the cartridge in the unopened, filled state of the cartridge with an inclination of up to 45 ° is not present at the ventilation duct mouth (83).

Furthermore, it is advantageous in this case to arrange the ventilation channel opening approximately in the middle of or in the chamber wall of the cartridge head.

To ensure the functionality, for example, even after a horizontal position of the cartridge, it is advantageous if the viscosity of a flowable preparation and the ventilation duct are configured in such a way that the preparation is not drawn via capillary forces in the ventilation duct when the preparation at the Vent duct opening is present.

The coupling of the cartridge with the dosing device is advantageously to be designed such that a dosing device communicating with the inlet opening of the dosing device is arranged on the dosing device, which cooperates with the dockable cartridge or cartridge chamber in such a way that when coupling the ventilation opening of the cartridge or ,

Cartridge chamber with the dosing of the mandrel displaced a volume Δν in the ventilation channel, whereby a pressure Δρ is generated in the ventilation duct, which is suitable to transport in the ventilation duct, flowable preparation in the connected to the ventilation duct, preparation-storing chamber.

It is preferred that the vent opening of a chamber is communicatively connected to the metering device side mandrel before the closed outlet opening of the corresponding chamber is opened, for example by the communicating connection with the inlet opening of the metering device.

According to a further advantageous embodiment of the invention is between

Ventilation opening and the ventilation channel arranged a ventilation chamber.

The cartridge may be configured to be detachable or fixed in or on the

Inlet openings of the dosing device are arranged and configured such that they are connected by the pivoting in the locked state in the coupling state of dosing device and cartridge sequentially with each other.

At the metering device and / or the cartridge can according to another advantageous

Design means may be formed, which cause a releasable fixation of the cartridge on the dosing in the coupling state of dosing and cartridge.

It is also advantageous to form means on the dosing device and / or cartridge which, in the latched state of the cartridge and the dosing device, cause the cartridge to be guided during pivoting into the coupling state of the cartridge and dosing device. This can be realized, for example, by a collar running on the bottom of the cartridge, which is set back slightly relative to a corresponding dosing device-side collar, so that it is guided on the cartridge-side collar inside the dosing device-side collar.

In particular, it is advantageous that the outlet openings of the chambers are arranged one behind the other in the pivoting direction. It is very particularly preferred that the outlet openings of the chambers are arranged in the pivoting direction on a line (L).

Furthermore, it is advantageous that the outlet openings of the chambers have approximately the same distance from each other.

In a further advantageous embodiment of the invention corresponds to the largest distance of an outlet opening of a chamber from the pivot point (SP) of the cartridge in about 0.5 times the distance of the cartridge width (B). In particular, at least two chambers of the cartridge may have different volumes from each other.

Advantageously, the chamber of the cartridge with the largest volume on the largest distance from the pivot point (SP) of the cartridge 1.

In a further embodiment of the invention, the ventilation opening of a chamber in the pivoting direction when coupling the cartridge with the dosing device is in each case in front of an outlet opening of the chamber.

Preferably, the ratio of depth (T) of the cartridge to width (B) of the cartridge is about 1:20. The ratio of height (H) of the cartridge to width (B) of the cartridge is preferably about 1: 1.2.

It is also preferred that the ventilation opening of a chamber in the pivoting direction when coupling the cartridge with the metering device is in each case in front of an outlet opening of the chamber. This ensures that the ventilation opening of the cartridge is first opened before the opening of the outlet opening of the cartridge takes place when the cartridge is coupled to the dosing device.

Therefore, the enzymes can interact with Accompanying substances, for example, from the fermentation or stabilizers are assembled and used.

Measurement of specific heat capacity cp

The determination of the specific heat capacity c _p of solid and liquid substances was carried out by differential scanning calorimetry (DSC). The used

Method is described in more detail below:

The determination consists of the following individual steps:

• Measurement of the DSC baseline (empty sample crucible) in the temperature range of interest

• Measurement of the DSC curve from the sample (in the same crucible pair)

• Calculation of the specific heat capacity at the desired temperature (s)

By means of a thermal analyzer with DSC cell (for example DSC 7 from Perkin Elmer), the specific heat capacity can be determined in a temperature range of about -10 to 600 ° C. Since vaporizing sample components would falsify the measurement results, encapsulated measuring crucibles are used (in this case AI crucibles from TA-Instruments, which are pressure-tight up to approx. 2 - 3 bar), reduce these disturbances. The bursting of crucibles or any leaks in the crucible can be seen in the DSC diagram.

The specific heat capacity c _p (J ^* g ^{~ *} K ^{~ 1} ) of a substance is a characteristic thermodynamic quantity. It is temperature-dependent and indicates how much energy must be expended to heat one gram of a substance at constant pressure by one Kelvin.

AQ

c _p =

= specific heat capacity (J * g ^"1 * K ^{" 1} ) at constant pressure p = required heat quantity (J)

m = mass (g)

T ₂ -T: = temperature increase from Tj to T ₂ (K) The devices / accessories used for the analysis method described are listed below:

In the DSC measurement, a sample (weigh about 5 - 15 mg) is usually heated at a constant rate. The deflection between the DSC measurement signal of the sample and the baseline (DSC measurement crucible without sample) is proportional to the specific heat capacity of the sample.

It is recommended that the encapsulable crucibles be pre-aligned with e.g. Clean acetone in an ultrasonic bath. Any adhering oil residues are thereby removed and the cold welding during encapsulation is improved. Another important factor is the stability of the baseline, which is influenced by many factors. The baseline is to be recorded under completely identical measuring conditions. Measurement conditions for the DSC 7 from Perkin Elmer are listed below:

FIGS. 30 and 31 show the c _p measurement of a sample according to the 2-curve c _p method, ie the standard measurement method. Figure 30 shows the primary baseline DSC measurements (2 non-encapsulated, empty crucibles) and sample measurement (encapsulated sample and assay) Empty cup). Figure 31 shows the calculated specific heat capacity curve c _p (J ^* g ^{~ *} K ^{~ 1} ) and the total enthalpy difference (J / g) in the temperature range of -15 - 35 ° C. The corresponding values can be found in the representative diagram.

Cp Preparation Chamber 3 (Enzyme Chamber) 2.61 J / (g ^* K) The composition of the enzyme chamber of the cartridge used was composed as follows:

After 25 rinsing cycles in the 70 ° rinsing program of the Miele G1220, the activity of the enzyme phase was determined in a dishwasher from Miele type G1220 in a 50 ° C. normal rinsing program.

A number of different methods for determining the activity of enzyme proteins are known to the person skilled in the art. Methods for determining the activity of enzyme proteins are usually relative methods in which the enzyme protein activity is determined relative to a reference sample. Decisive is not the method itself, but the same method is used in the determination of the reference value and the actual sample.

For example, the activity of the amylases was determined as follows: Amylases convert starch to glucose. Under defined reaction conditions (0.5% strength, soluble, pretreated according to Zulkowsky, 50 mM sodium acetate pH 5, 40 ° C., 15 min), samples to be examined are incubated. Glucose and other reducing sugars react with p-hydroxybenzoic acid hydrazide 0.75% with 0.75 mM bismuth (each final concentration) to a yellow dye and thus can after completion of the reaction and 10 minutes incubation with the dye at 70 ° C. in alkaline conditions (addition of 0.375 M NaOH

(Final Concentration) The last two points are carried out such that a 1% p-hydroxybenzene acid solution with 1 mM bismuth in 0.5 M NaOH is used, this is added in a ratio of 3/4 to 1/4 to the incubated enzyme Substrate solution given.) Can be determined photometrically at 410 nm. The amount of sugar released is a measure of the enzyme activity. The specification in CAE / g is made by reference to a corresponding calibration series of a reference enzyme.

Methods for determining protease activity are disclosed, for example, in Tenside, Vol. 7 (1970), pp. 125-132. The proteolytic activity can also be determined via the Release of the chromophore para-nitroaniline (pNA) from the substrate suc-L-Ala-L-Ala-L-Pro-L-Phe-p-nitroanilide (suc-AAPF-pNA). The protease cleaves the substrate and releases pNA. The release of pNA causes an increase in absorbance at 410 nm, the time course of which is a measure of enzymatic activity (see Del Mar et al., 1979). The measurement takes place at a temperature of 25 ° C, at pH 8.6 and a wavelength of 410 nm. The measuring time is 5 min at a measuring interval of 20 s to 60 s. The protease activity is preferably indicated in CPE (protease units).

The following table shows the enzyme activity readings at the beginning of the measurement

(Reference value) and after 25 cycles in the 70 ° C program of the above Miele

Dishwasher for proteases and amylases listed:

It can be seen that the enzyme activities have only a slight loss and that a sufficiently high enzyme stability is still present even after 25 rinses.

shows a self-sufficient dosing device 2 with a two-chamber cartridge 1 in the separated and assembled state.

The metering device 2 has two metering chamber inlets 21a, 21b for repeatedly releasably receiving the corresponding outlet openings 5a, 5b of the chambers 3a, 3b of the cartridge 1. On the front are display and controls 37, which indicate the operating state of the dosing device 2 and act on this.

The Dosierkammereinlässe 21a, 21b further comprise means for the insertion of the cartridge 1 on the dosing device 2, the opening of the outlet openings 5a, 5b of the chambers 3a, 3b effect, so that in the coupled state of dosing device 2 and cartridge 1, the interior of the chambers 3a, 3b communicating with the Dosierkammereinlässen 21a, 21 b is connected.

The cartridge 1 may consist of one or more chambers 3a, 3b. The cartridge 1 may be integrally formed with a plurality of chambers 3a, 3b or more pieces, in which case the individual chambers 3a, 3b are joined together to form a cartridge 1, in particular by cohesive, positive or non-positive

Connection methods.

In particular, the fixation by one or more of the types of compounds from the group of snap-in compounds, press joints, fusions,

Adhesive bonds, welded joints, solder joints, screw, wedge, clamp or bounce joints done. In particular, the fixation can also be formed by a shrink sleeve (so-called sleeve), which is pulled in a heated state at least in sections over the cartridge and firmly encloses the cartridge in the cooled state.

In order to provide advantageous residual emptying properties of the cartridge 1, the bottom of the cartridge 1 may be funnel-shaped inclined to the discharge opening 5a, 5b. Furthermore, the inner wall of the cartridge 1 can be formed by suitable choice of material and / or surface design in such a way that a low material adhesion of the product to the inner cartridge wall is realized. Also by this measure, the residual emptying of the cartridge 1 can be further optimized.

The chambers 3a, 3b of the cartridge 1 may have the same or different filling volumes. In a two chamber configuration 3a, 3b, the chamber volume ratio is preferably 5: 1, in a three chamber configuration preferably 4: 1: 1, these configurations being especially suitable for use in

Dishwashers are suitable.

A connection method can also be that the chambers 3a, 3b are inserted into one of the corresponding metering chamber inlets 21a, 21b of the metering device 2 and thus fixed against each other.

The connection between the chambers 3a, 3b may in particular be made detachable in order to allow a separate exchange of a chamber.

The chambers 3a, 3b each contain a preparation 40a, 40b. The preparation 40a, 40b may have the same or different composition.

Advantageously, the chambers 3a, 3b are made of a transparent material, so that the filling level of the preparations 40a, 40b is visible from the outside by the user. However, it may also be advantageous to manufacture at least one of the chambers from an opaque material, in particular when the preparation contained in this chamber contains light-sensitive ingredients.

The outlet openings 5a, 5b are designed such that they form a positive and / or non-positive, in particular liquid-tight, connection with the corresponding metering chamber inlets 21a, 21b.

It is particularly advantageous that each of the outlet openings 5a, 5b is formed so that it fits only one of the Dosierkammereinlässe 21a, 21b, thereby preventing a chamber is accidentally plugged onto a wrong Dosierkammereinlass. This can be realized, for example, by outlet openings 5a, 5b and / or metering chamber inlets 21a, 21b which are different in size or different in their basic form.

The cartridge 1 usually has a filling volume of <5,000 ml, in particular <1,000 ml, preferably <500 ml, more preferably <250 ml, most preferably <50 ml.

The dosing unit 2 and the cartridge 1 can in the assembled state

In particular, the geometries of the devices or in which they are applied to be adapted to ensure the least possible loss of useful volume. To use the dosing unit 2 and the cartridge 1 in dishwashers, it is particularly advantageous to the dosing unit 2 and the cartridge 1 based on in

Dishwashers form to be cleaned dishes. Thus, the dosing unit 2 and the cartridge 1, for example, plate-shaped, approximately in the dimensions of a plate, be educated. As a result, the dosing unit can be positioned to save space in the lower basket.

The outlet openings 5a, 5b of the cartridge 1 are preferably arranged on a line or in alignment, whereby a slender, plate-shaped design of the dosing dispenser is made possible. shows a self-sufficient dosing with a two-chamber cartridge 1 in the dish drawer 1 1 with the dishwasher door 39 of a dishwasher 38. It can be seen that the dosing device 2 with the cartridge 1 is in principle positionable anywhere within the dish drawer 1 1, wherein It is advantageous to provide a dish-shaped or cup-shaped metering system 1, 2 in a corresponding plate or cup receptacle of the dish drawer 1 1. In the dishwasher door 39 is a metering chamber 53, in which a dishwasher cleaner preparation can be given, for example in the form of a tablet. Is the dosing 1, 2 in the ready state inside the dishwasher 38, so is a

Cleaning preparation addition for each rinse cycle on the metering chamber 53 is not necessary because a detergent dispensing is realized for a plurality of rinse cycles on the dosing system 1, 2, which will be explained in more detail below. It is advantageous in this embodiment of the invention that when the self-sufficient dosing system 1, 2 in the lower dish drawer 1 1, the delivery of the preparations 40a, 40b from the cartridge 1 directly over the bottom of the dispenser arranged outlet openings in the

Rinse water liquor is done so that a quick solution and uniform distribution of the rinse formulations is guaranteed in the wash program. shows a two-chamber cartridge 1 in the separated state to a self-sufficient dosing device 2 and an internal, machine-integrated dosing. In this case, the cartridge 1 is designed in such a way that it can be coupled to both the self-sufficient dosing device 2 and the machine-integrated dosing device (not shown, for example, in the dishwasher door 39), which is indicated by the arrows in dargstellten.

On the inside of the dishwasher 38 directed side of the

Dishwasher door 39 is formed a recess 43 into which the cartridge 1 can be inserted, wherein the insertion of the outlet openings 5a, 5b of the cartridge 1 communicating with the adapter pieces 42a, 42b are connected by the insertion. The

Adapter pieces 42a, 42b are in turn coupled to the machine-integrated dosing device. For fixing the cartridge 1 in the recess 43 holding elements 44a, 44b may be provided on the recess 43, which ensure a positive and / or positive fixing of the cartridge in the recess 43. Of course, it is also conceivable that corresponding retaining elements are provided on the cartridge 1. The holding elements 44a, 44b may preferably be selected from the group of snap-in connections,

Snap-in connections, snap-lock connections, clamp connections or

Connectors.

During operation of the dishwasher 38, preparation 40a, 40b from the cartridge 1 through the adapter elements 42a, 42b is added to the corresponding rinsing cycle by the machine-integrated dosing device. shows the known cartridge 1 in the installed state in the door 39 a

Dishwasher 38. It can be seen that by integrating the dosing unit 2 and the cartridge 1 in the door 39 of the dishwasher, no space is lost in the dish drawer 1 1 for items to be washed, which is a significant advantage of this embodiment.

A further embodiment of the invention is shown in FIG. 1, which shows the known cartridge 1 with a chamber 45 arranged at the head of the cartridge 1, which has a plurality of openings 46 in its lateral surface. Preferably, the chamber 45 is filled with an air freshener formulation which is delivered through the openings 46 to the environment. The air-conditioning preparation may in particular comprise at least one fragrance and / or an odor-controlling substance.

Unlike the known and known arrangement of the cartridge 1 inside a dishwasher 38, it is also possible, a recess 43 with adapter elements 42 a, 42 b for coupling with the cartridge 1 on an outer surface of a

Dishwasher 38 provided. This is exemplified in and illustrated. This embodiment may be of advantage in particular for very temperature-sensitive preparations 40a, 40b, since they usually occur in the rinsing program

Temperature fluctuations are not directly exposed.

Of course, the cartridge 1 shown in and also with a

Chamber 45 containing air freshening substance may be arranged in a correspondingly formed receptacle in the interior of a dishwasher 38.

A further embodiment of the invention is shown in and FIG. The dosing device 2 can in this case be coupled to the cartridge 1, which is indicated by the first, left arrow in the drawing accordingly. Subsequently, cartridge 1 and dosing device 2 coupled as an assembly via the interface 47,48 to the dishwasher, which is indicated by the right arrow. The dosing device 2 has an interface 47, via which data and / or energy are transferred to and / or from the dosing device 2. In the door 39 of the dishwasher 38, a recess 43 for receiving the dosing device 2 is provided. In the depression 43, a second interface 48 is provided, which transmits data and / or energy to and / or from the dosing device 2.

Preferably, data and / or energy are exchanged wirelessly between the first interface 47 on the dosing device 2 and the second interface 48 on the dishwasher 38. It is particularly preferred that energy from the interface 48 of the dishwasher 38 is transmitted wirelessly via the interface 47 to the dosing device 2. This can be done, for example, inductively and / or capacitively.

It is also advantageous to form the interface for transmitting data wirelessly. This can be realized by the methods known in the art for the wireless transmission of data, such as by radio transmission or IR transmission. It is particularly preferred to form the transmission of data and signals wirelessly by means of optical transmission technologies in the visible range.

Alternatively, the interfaces 47, 48 can also be formed by integrated plug connections. Advantageously, the connectors are formed in such a way that they are protected from the entry of water or moisture.

FIG. 8 shows the dosing system 1, 2 in the state coupled to the dishwasher 38 in the recess 43 of the dishwasher door 39. FIG. 1 shows a cartridge 1 whose chambers 3a, 3b can be filled via the head-side openings 49a, 49b, for example by means of a refill cartridge 51. The openings 49a, 49b of the cartridge 1 may be formed, for example, as silicone valves, which open when piercing through the adapter 50a, 50b and close again upon removal of the adapter 50a, 50b, so that an inadvertent leakage of preparation from the cartridge is prevented.

The adapters 50a, 50b are formed to define the openings 49a, 49b of the

Cartridge 1 can pierce. Advantageously, the openings 49a, 49b of the cartridge 1 and the adapters 50a, 50b are configured with regard to their position and size in such a way that the adapter can engage in the openings 49a, 49b only in a predefined position. In this way, in particular, incorrect filling of the cartridge chambers 3a, 3b can be prevented and it is ensured that the respective same or compatible Preparation from a chamber 52a, 52b of the refill cartridge 51 in the corresponding chamber 3a, 3b of the cartridge 1 passes.

Further exemplary embodiments of the cartridge known from the preceding figures are shown in FIGS.

In a first embodiment, which is shown in FIG. 1, the cartridge 1 consists of a first tub-shaped element 6 and a second plate-like or lid-like element 7, wherein in FIG. 10 the two elements 6, 7 are shown in the unassembled state. The second, plate-like or lid-like element 7 is such

dimensioned so that it completely covers the first trough-shaped element 6 along the connecting edge 8 in the assembled state of the cartridge 1.

The first trough-shaped element 6 is replaced by the cartridge head 10, the

Cartridge side surfaces 1 1 and 12 and the cartridge bottom 4 is formed. Through the divider 9, the two chambers 3a, 3b of the cartridge 1 are defined. At the

Cartridge bottom 4 are each an outlet opening 5a, 5b provided for each of the chambers 3a, 3b. The cartridge 1 is formed by materially joining the first trough-shaped element 6 to the second, plate-like or cover-like element 7, wherein the connecting edge 8 does not intersect the outlet openings 5a, 5b of the cartridge 1 in the assembled state.

Another embodiment of the cartridge shows the, in which also two cartridge elements are to see 6,7 in not yet assembled state. The two cartridge elements 6,7 are mirror-symmetrical, so that in the assembled state the connecting edges 8 of the two elements 6, 7 completely rest against one another. The outlet openings 5a and 5b are formed only at the bottom 4 of the first cartridge element 6, so that the connecting edge 8 of the elements 6,7 on the cartridge bottom 4 outside the outlet openings 5a, 5b runs and the

Connecting edge 8, the outlet openings 5a, 5b so does not cut. In this way, a safer sealing of the outlet openings 5a, 5b can be ensured, since

Material deformations in the region of the outlet openings 5a, 5b designed more uniform in particular due to thermal stresses and not by a shock or

Connecting edge 8 uneven deformation occurs, which can subsequently lead to undesirable sealing problems, especially when inserting the cartridge and / or during the temperature changes within a wash program. shows a modification of the known and known cartridge. In this embodiment, the first cartridge element 6 as a one-piece cup-shaped, bottomless plastic container designed. The cartridge 1 is formed by inserting the bottom 4 to the container 6 along the connecting edge 8, which is indicated by the arrow in the figure. The bottom 4 has a first opening 5a and a second opening 5b which, in the assembled state of the cartridge 1, allow outflow of preparation from the respective chambers 3a, 3b. Again, the connecting edge 8 extends in the assembled state of the cartridge 1 outside the outlet openings 5a, 5b.

Alternatively, it is also conceivable that a cartridge element 6 is formed as a cup-shaped, open-topped container with the chambers 3a, 3b and the second element as a cartridge cover 10 which is liquid-tightly connected to the cup-like, open top container along the connecting edge 8, in turn the connecting edge 8 in the assembled state of the cartridge 1 outside the outlet openings 5a, 5b extends, as is apparent from the.

The fact that the cartridge 1 can also be formed from two mutually separately formed chambers 3a, 3b is shown in FIG. In particular, in this case the chambers 3a, 3b may be formed by a blow molding process. The two chambers 3a, 3b are in this

Design variant material, positive and / or non-releasably connected to each other and thus form the cartridge. 1 shows the known cartridge 1 as a receptacle for a filled with preparation 40 bag 64, so that by inserting the bag into the cartridge chambers, which is indicated by the arrows in the figure, formed a so-called "bag-in-bottle" container The openings 65a, 65b of the bag 64a, 64b are formed in such a way that they can be inserted into the openings 5a, 5b of the cartridge 1. Preferably, the openings 65a, 65b are formed as dimensionally stable plastic cylinders. However, it is also possible that one bag 64a, 64b is positioned in a corresponding chamber of the cartridge 1, but one connected via a web 66

Form multi-chamber bag, which is used as a whole in the cartridge. After inserting the bag 64 into the cartridge 1, it is detachably closed by the cartridge head 10. It is particularly advantageous to avoid an undesirable loss of

Cartridge head 10 to prevent, for example, by means of a material bridge pivotally to the cartridge 1 to fix.

FIG. 12 shows a further development of the known cartridges, in which a further chamber 45 for receiving a preparation is arranged on the cartridge and configured in such a way that a discharge of volatile substances from the preparation into the environment of the chamber 45 is effected. In the chamber 45, for example volatile perfume or air freshening substances are, which are discharged through the openings 46 of the chamber 45 to the environment.

It can also be seen that the openings 5a, 5b are closed by silicone valves which have an x-shaped slot. This prevents that upon release of the cartridge 1 from the dosing device 1, 40 preparation from the decoupled cartridge 1 exits.

FIG. 17 shows a cartridge 1 with individually exchangeable chambers 3a, 3b, 3c in plan view. The chambers 3a, 3b, 3c are formed by mutually corresponding contours of their lateral surfaces so that they can be assembled to form a cartridge 1 only in a specific, defined arrangement to each other. This makes it possible, in particular, to provide individually exchangeable chambers without any undesired arrangement of the chambers and their corresponding preparations with respect to one another. shows a further possible embodiment of the cartridge 1 with three chambers 3a, 3b, 3c. The first chamber 3a and the second chamber 3b have an approximately equal filling volume. The third chamber 3c has a filling volume about 5 times that of one of the chambers 3a or 3b. The cartridge base 4 has a ramp-like shoulder in the region of the third chamber 3c. This asymmetrical design of the cartridge 1 can ensure that the cartridge 1 can be coupled with the dosing device 2 in a position provided for this purpose and that it can be inserted in a wrong position through a

Corresponding embodiment of the dosing device 2 or the console 54 is prevented.

In the plan view of the cartridge, which is shown in FIG. 5, the separating webs 9a and 9b can be seen, which separate the chambers of the cartridge 1 from one another. The well-known and known cartridge can be formed in different ways.

In a first variant, which can be seen, the cartridge 1 is formed from a first tub-like cartridge element 7 and a second, lid-like or plate-like cartridge element 6. In the trough-like cartridge element 7, the separating webs 9a and 9b are formed, through which the three chambers of the cartridge 1 are formed. At the bottom 4 of the trough-shaped cartridge element 7, the outlet openings 5a, 5b, 5c are respectively arranged below the chambers of the cartridge 1.

As can also be seen, the bottom 4 of the cartridge in the region of the third chamber 3c has a ramp-like shoulder which forms a gradient in the direction of the third outlet opening 5c on the bottom of the chamber. This will ensure that in this chamber 3c always directed preparation in the direction of the outlet opening 5c and so a good residual emptying of the chamber 3c is achieved.

In the assembled state of the cartridge 1, the trough-shaped

Cartridge element 7 and the cover-like cartridge element 6 along the common connecting edge 8 cohesively connected to each other. This can be realized for example by welding or gluing. Of course, in the assembled state of the cartridge 1, the webs 9a, 9b are also firmly bonded to the cartridge element 6.

In this case, the connecting edge 8 does not run through the outlet openings 5a-c, as a result of which leakage problems, in particular in the state coupled to the dosing device, are avoided in the region of the openings 5a-c.

Another variant for the formation of the cartridge shows. This is the first one

Cartridge element 6 cup-shaped and has an open bottom. The separately formed bottom 4 can be used as a second cartridge element 7 in the bottom-side opening of the cup-like cartridge element 6 and along the common

Connecting edge 8 are materially connected. Advantage of this variant is that the cup-like element 6 is produced inexpensively by a plastic blow molding process.

Figure 22 shows a further embodiment of the cartridge 1 and the dosing device 2 in the non-coupled state. The cartridge 1 from FIG. 21 will be explained in more detail with reference to FIG.

FIG. 22 shows the cartridge 1 known from FIG. 21 in a perspective view. At the cartridge bottom 4 are alternately outlet openings 5 and 5

Ventilation openings 81 arranged. For each of the chambers in the cartridge 1, an outlet opening 5 and a ventilation opening 81 are respectively provided. The width (B) is substantially greater than the depth (T) of the cartridge 1. The ratio of the depth (T) to the width (B) of the cartridge 1 is approximately 1:20.

The area of the cartridge bottom 4, on which the outlet and ventilation openings are arranged, is enclosed by a circumferential collar 99 (see also FIG. 23). This collar 99 causes on the one hand a structural reinforcement of the cartridge 1 in the bottom region, which is especially the case when inserting the cartridge 1, when on the

Floor area 4 corresponding contact forces for coupling the cartridge 1 with the dosing device 2 act, prevents deformation in the bottom portion 4, so that a controlled and safe insertion of the cartridge 1 is made possible in the dosing device 2. Furthermore, the collar 99 provides protection against undesirable mechanical effects on the closures of the outlet and ventilation openings. As can be seen from FIG. 22 and FIG. 23, the outlet and ventilation openings 5, 81 are set back relative to the collar 99, so that the openings 5, 81 are protected, for example, from the direct action of objects which are larger than the openings.

As can also be seen from FIG. 23, the outlet and ventilation openings 5, 81 each have a collar 100. This collar 100 enclosing the outlet and ventilation openings 5, 81 also serves to structurally reinforce the outlet and outlet openings

Ventilation openings 5.81 in the bottom region 4 of the cartridge 1. Furthermore, the collar 100 can serve as a fastening for closure means of the outlet and ventilation openings 5, 81, for example for sealing plugs or closure covers.

The collar 100 of one of the outlet and vent openings 5, 81 is set back relative to the collar 99, so that the collar 100 does not protrude beyond the edge of the collar 99.

It can also be seen from FIG. 23 that the cartridge 1 is asymmetrical with respect to its axis Z-Z. This asymmetry causes the cartridge 1 in only one defined way with the dosing device 2 - in particular with the

Inlet openings 21 of the metering device 2 - can be coupled. As a result, a mechanical key-lock principle between the cartridge 1 and metering device 2 is formed, which prevents incorrect operation when coupling the cartridge 1 to the metering device 2.

The asymmetry of the cartridge 1 is inter alia also caused by the fact that the bottom 4 has two levels, the first level through which the outlet and

Ventilation openings 5,81 enclosing collar 99 is formed and the second level is a bottom portion which is offset via a ramp 104 to the cartridge head 10, which can be seen well in Figure 22 and Figure 23, for example.

Starting from the ramp 104, a further collar 105, which has an opening 106, extends from the bottom section of the second plane. The opening 106 forms with a corresponding engagement of the dosing device 2 a releasable latching connection for securing the coupling state of the cartridge 1 with the dosing device 2.

In addition, a peripheral edge 101 in the lower, bottom-side region of the cartridge 1 can be seen in FIG. From this edge 101 extends in the bottom direction, a circumferential wall portion 102 of the cartridge 1, to the interior of the cartridge first is set back, so that between the edge 101 and wall portion 102 a to the interior of the cartridge extending shoulder is formed.

The metering device 2 is designed such that the circumferential wall portion 102 can be inserted into the collar 103 of the metering device 2 (see also Figure 28-29), wherein in the coupling position of the cartridge 1 and metering device 2, the edge 101 of the cartridge on the collar 103 of the dosing device rests, so that of the collar 103 of the

Dosing device 2 enclosed space is at least protected against splash water entry. The collar 103 of the dosing device 2 and the edge 101 of the cartridge can in particular also be configured so that in the coupling state of the cartridge 1 and dosing device 2 an entry of water in the space enclosed by the collar 103 of the dosing device by a substantially dense resting of the edge 101st is prevented on the collar 103.

Furthermore, the inwardly offset wall portion 102 of the cartridge in conjunction with the Dosiergerätesigen collar 103 causes a guide of the cartridge 1 when inserted into the dosing device second

The cartridge 1 is formed from two elements which are welded together in a form-fitting manner at the peripheral connecting edge 8. FIG. 24 shows the cartridge 1 known from FIG. 23 with a lid-like element removed along the connecting edge 8, so that FIG. 24 shows an insight into the interior of the cartridge 1.

It can be seen that the cartridge 1 is subdivided into three chambers by the two separating webs 9a, 9b, each of the chambers having a bottom side in the direction of gravity

Outlet opening 5 has.

At the bottom end of the dividers 9 ventilation chambers 86 are arranged, the inside of the cartridge enclose the ventilation openings 81. On the one hand, the ventilation chambers 86 serve to structurally reinforce the cartridge bottom 4 in the region of the ventilation openings 81, so that deformation during coupling of the cartridge 1 to the dosing device 2 is prevented, and, on the other hand, the connection between the ventilation openings 81 and the ventilation channels 82 FIGS. 24-26, the ventilation chambers 86 are of cuboid design. The vent chambers 86 are communicatively connected to the vent passage 82 (not shown in Figs. 24-26).

FIG. 26 shows the cartridge 1 and the dosing device in the coupled state in a cross-sectional view. It can be seen that the thorn-like inlets 21, in the coupled state of metering device 2 and cartridge 1, protrude into the interior of the cartridge chambers 3 or the ventilation chambers 86, in particular the spike-like inlets 21 of the dosing device 2 with the outlet openings 5 of the cartridge form a liquid-tight connection, so that preparation from the chambers 3 can only enter through the interior of the mandrel-like shaped inlets 21 into the dosing device 2. As can further be seen well from FIG. 26, the outlet openings 5a-c and the ventilation openings 81a-c lie in a line, wherein each outlet opening 5a-c is assigned a corresponding ventilation opening 81a-c.

In Figure 27, the formation of a ventilation duct by joining two

Cartridge elements 6,7 shown schematically. In the upper part of FIG. 27, the two cartridge elements 6, 7 are shown in the separated state. The cartridge element 7 is plate-like, with two spaced-apart webs 84, 85 extending perpendicularly from the cartridge element 7. The webs 84, 85 are configured so that they can comprise a web 9 formed on the cartridge element 6, which can be seen in the lower part of FIG. The fit is chosen so that the inner sides of the webs 84,85 touch the web 9 lightly. The two webs 84,85 and the web 9 form in the assembled state of the cartridge elements 6,7

Ventilation channel 81 off. It is particularly advantageous to connect the ends of the webs 84, 85 to the web 9 in a material-locking manner, in particular by welding. The mirror and / or laser welding has proven to be particularly advantageous.

In Figure 28, the dosing device 2 and the cartridge 1 is shown in the uncoupled state. It can be seen the recess 97 in the cartridge 1 below the outer chamber 3a. The indentation 97 is approximately semicircular in shape and has a shoulder 94 at its bottom end. The indentation 97 and the shoulder 94 are configured such that the shoulder 94 can be introduced into a recess 98 of the dosing device 2 by a pivotal movement of the cartridge 1 when coupling the cartridge 1 with the dosing device 2. This is shown by way of example in FIG. 29. Due to the detachable connection between the dosing device side recess 98 and the cartridge side shoulder 94, the cartridge 1 when coupling the cartridge 1 with the dosing device 2 by the indicated

Pivoting movement (arrow) pivotally fixed. It can be seen that when coupling by the pivoting movement about the connection of the recess 98 and shoulder 94 around, a sequential opening or coupling of the outlet openings 5a, 5b, 5c and ventilation openings 81 takes place. First of all, when the cartridge 1 and metering device 2 are coupled for the first time, a ventilation opening 81a-c is opened by pivoting, before the assigned one

Outlet opening 5a-c is pierced. After completion of the pivoting movement, the snap-in elements 95 and 96 on the cartridge 1 and the dosing device 2 secure the cartridge 1 in the coupling position. The snap-in elements 95, 96 are designed such that the

Locking by the user is releasable, for example by squeezing the clip-like snap-in element 96 and by a pivoting movement about the connection between recess 98 and shoulder 94 cartridge 1 and dosing device 2 can be solved again from each other.
