A pack filled with an active substance in the form of a compact tablet, the pack having a film forming a holding cup, the tablet being accommodated in the holding cup, wherein an edge of the tablet at the bottom of the holding cup corresponds in its profile to the edge profile of the holding cup.

Description

The invention relates to a method for producing a packaging filled with an active agent, in particular a detergent, in tablet form.

The teaching of the invention can be used for the production of active ingredient compositions in tablet form, which are sold in a suitable packaging. Detergents such as laundry detergents and dishwashing detergents, as well as other water-soluble detergents and cleaning auxiliaries, such as bleaches, color protectants, fragrance formulations, enzyme active agent agents, etc., come into question as active ingredients. However, the method is also applicable to other active agents which are to be marketed in tablet form in a protective packaging on the market.

However, a particular field of application of the process according to the invention is in fact all forms of detergents and washing auxiliaries and dishwashing detergents in tablet form. Another field of application are water-soluble adhesives, in particular pastes, in tablet form, which are used for the production of large-area bonds, for example for the bonding of wallpapers.

The preparation of active ingredient compositions, in particular detergents, in tablet form from usually finely crystalline, powdered or granulated raw materials is generally carried out with the addition of fillers, binders, disintegrants, lubricants or the like. by pressing. The starting material is e.g. compressed in eccentric presses or rotary presses with the right pressure for the respective product.

It is known to package active ingredient, in particular detergent, in tablet form. On the one hand, this protects the tablet against mechanical stress, on the other hand, skin-aggressive components are occasionally processed in cleaning agents, so that contact between the tablet and the skin is avoided by the packaging. Finally, it is avoided by the packaging that the compressed in tablet form active agent, in particular cleaning, prematurely absorbs moisture from the ambient air.

As packaging for active ingredient, in particular detergents, so-called flow packs are known. In these active ingredient compositions in tablet form are usually made up in pairs. In each case two such tablets are required, for example, in a conventional detergent / washing aid compound for a wash and are packaged in a flowpack distributed in the interior (DE 198 40 390 A1). Also for water-soluble adhesives in tablet form are known from practice flow packs.

A common type of packaging for active ingredient tablets in tablet form is blister packaging. This has also found in the field of cleaning agents in tablet form input (EP 0 903 405 A2). In the known prior art so far a dishwashing composition of certain recipe is proposed, which is present compressed in tablet form. The preparation of the tablets is carried out in the usual way on a normal tablet press, for example a rotary press. The tablets produced by the rotary press are collected and placed in a pick and place machine in the receiving cavities of an already preformed packaging film. As soon as the receiving troughs have been equipped with appropriate tablets, they are hermetically sealed on the open side by applying a closing foil, which in particular is welded or glued on. When manufacturing in a continuous process then corresponding strips of the closed packaging, in the illustrated embodiment, each comprising eight receiving wells, separated and finished ready as a sales unit.

The use of a blister pack for active ingredient tablets in tablet form makes it possible to pack different active ingredients, which are incompatible with one another, in separate receiving troughs and meter them individually. Skin contact with the active agent is readily preventable. It is also possible to build a sales unit from several rows of receiving troughs, which are equipped with different active agent agents, for example, on the one hand detergent, on the other hand washing aids, (see also DE 42 38 421 A1).

The known blister pack has a packaging film of plastic, in particular of a thermoplastic, transparent or translucent plastic, such as polyethylene.

The packaging of the tablets of the active ingredient in a blister pack allows to choose the formulation of the active agent somewhat more freely because the requirements for dimensional stability of the tablet are lower. Even if the tablet should break, the amount of active ingredient remains so in the receiving trough held until use and is therefore still usable for the user. In particular, the previously mentioned transparent packaging can represent a considerable incentive to buy for the customer.

Blister packagings for active ingredient compositions in tablet form are also known for a water-soluble adhesive, in particular a paste, for a long time (DE 42 00 188 A1). This prior art also discloses the usual formulations for water-soluble adhesives based on natural starting materials or water-soluble derivatives of cellulose and starch.

The known process for the preparation of a tablet-filled packaging from which the invention is based (US Pat. No. 5,662,849A), works in such a way that the tablet form of the active ingredient is produced directly in a molded-in receiving well of a packaging-forming film. Such preformed packaging-forming film usually with a plurality of receiving wells is used with the receiving wells in matching receptacles of a holding mold. In the receiving troughs a certain amount of the not yet pressed active agent (premix) is filled in each case. The present in the receiving wells amounts of the active ingredient are pressed into the receiving wells themselves by means of a mold using the recordings of the holding form as an abutment in each case to a compact tablet. Thereafter, the preformed packaging film is sealed with the now in the receiving troughs active ingredient tablets on the open side by applying a closing film or a lid.

In the known method explained above, therefore, the method steps "tablet pressing" and "tablet packaging" are combined in a single method. The direct compression of the tablets in the receiving troughs of the film eliminates the problem of edge breakage and abrasion when handling the tablets in placement machines. A conventional air conditioning of the production rooms can be reduced and limited to the supply of the unpressed raw material of the active agent.

The previously explained, known from the prior art method for producing a filled with tablets packaging has been well proven in practice, however, is procedural systematically perform only gradually and requires the preparation of a preformed packaging film with the necessary receiving troughs in a previous process step. The previously explained, known method is thus still improved in terms of the procedure.

• a) Eine verpackungsbildende Folie wird auf eine Halteform mit mindestens einer eine Aufnahmemulde bildende Aufnahme aufgelegt.
• b) Vor oder gleichzeitig mit Verfahrensschritt a) wird in einer der Halteform zugeordneten Preßform mit jeweils einer der Aufnahme der Halteform zugeordneten Premixaufnahme in die Premixaufnahme eine bestimmte Menge des noch nicht verpreßten Wirkstoffmittels (Premix) eingefüllt und darin vorgeformt.
• c) Die Form wird geschlossen und das vorgeformte Wirkstoffmittel wird aus der Premixaufnahme heraus auf die verpackungsbildende Folie und mit dieser gemeinsam, diese zu einer Aufnahmemulde verformend, in die Aufnahme der Halteform gedrückt und darin dann unter Nutzung der Aufnahme der Halteform als Widerlager zu einer kompakten Tablette verpreßt.
• d) Nach Abschluß des Verfahrensschrittes c) wird die Folie mit der in der Aufnahmemulde befindlichen Wirkstoffmittel-Tablette von der Halteform entfernt und weiteren Handhabungsstufen zugeführt.
• e) Vor, gleichzeitig mit oder nach Verfahrensschritt d) wird die Aufnahmemulde an der offenen Seite durch Aufbringen einer Schließfolie oder eines Deckels verschlossen.

The claimed method according to the invention for producing a packaging filled with tablet in an active ingredient, in particular with a cleaning agent, does not require a preformed packaging film. The following method steps are provided by the method according to the invention:

• a) A packaging-forming film is placed on a holding mold with at least one receptacle forming a receptacle.
• b) Before or at the same time as step a), a predetermined amount of the not yet compressed active agent (premix) is filled in a mold associated with the holding mold associated with a recording of the holding mold associated premix recording in the premix recording and preformed therein.
• c) The mold is closed and the preformed agent agent is pressed out of the Premixaufnahme on the package-forming film and this together, this deforming a receiving trough, in the receptacle of the holding mold and then using the recording of the holding form as an abutment to a compact Tablet pressed.
• d) After completion of the process step c), the film is removed with the located in the receiving trough active agent tablet from the holding mold and fed to other handling stages.
• e) Before, simultaneously with or after process step d), the receiving trough is closed at the open side by applying a closing film or a lid.

In the method according to the invention, a further production step is integrated into the method, namely the formation of the receiving trough or the receiving troughs in the packaging-forming film. The tablet is pressed on the one hand from the premix of the active agent, on the other hand and at the same time the packaging-forming film is deep-drawn into the receptacle of the holding mold. The tablet of the active agent is in this process on the one hand object of the pressing process, on the other hand force transmission means for the deep drawing process with respect to the packaging film.

The method according to the invention can be further configured by the fact that in process step c) the preformed active ingredient, in particular cleaning agent, is removed from the premix holder by means of a punch displaceably arranged in the die. Alternatively, a variant comes into question, which is characterized in that in step c) the pressing out of the preformed active ingredient from the premix by means of compressed air supply takes place. Both pressure generating mechanisms can also be used in combination.

Furthermore, it can be provided that, in method step c), the deformation of the packaging-forming film into the receptacle is facilitated by means of an air outlet from the receptacle of the holding mold or actively supported by means of air extraction from the receptacle of the holding mold.

Further preferred embodiments and further developments of the method according to the invention are the subject of the further dependent claims related to the method.

Incidentally, a package produced by the process according to the invention with an active ingredient tablet contained therein can usually be recognized by the fact that the edge of the tablet located at the bottom of the receiving trough has a different contour than the edge of the tablet facing the open side of the receiving trough, in particular more rounded is as that.

As already mentioned in the general part of the description, the process involves the production of a packaging filled with an active ingredient in tablet form. This may be a single packaging, which is cut off, for example, from the strip shown in FIG. But it can also be larger packaging groups act as the other embodiments clearly demonstrate.

Active agent of all kinds can be taken up by the method in a package. In particular, however, the explanation relates to cleaning agents, in particular detergents and washing aids for the cleaning of laundry, as well as detergents for dishwashers, etc. A particularly interesting field of application are also water-soluble Adhesives, especially paste, as an active agent and in the general part of the description explained. In particular, reference may be made to the prior art already mentioned therein with its disclosure of water-soluble adhesives in tablet form.

The blister strip shown in Fig. 1 from a thermoformable, thermoplastic plastic film, for example made of polyethylene, shows molded receiving troughs of an inner diameter of about 44 mm. This is a size of an active agent tablet suitable for detergents or dishwashing detergents of conventional composition. Of course, this size is only an example. The teaching of the invention is not limited to specific tablet sizes or tablet forms.

FIG. 2 clearly illustrates the basic principle of a process for the production of a packaging filled with tablets in an active ingredient, here in particular a detergent, as is known from US Pat. No. 5,662,849A. The process steps are as follows:

A preformed packaging-forming film 1 with at least one molded-in receiving trough 2, in the illustrated example four juxtaposed receiving troughs 2, is inserted with the receiving trough 2 into a suitable receptacle 3 of a holding mold 4. In the illustrated embodiment, the holding mold 4 side by side four recordings 3. Before, simultaneously with or after the previously described process step, a certain amount of not yet compressed active agent (Premix) is filled into the receiving trough 2. The holding mold 4 is assigned a pressing mold 6 provided with corresponding pressing projections 5. This is lowered as shown by arrows from the top of the holding mold 4. The amount of active ingredient present in the respective receiving trough 2 is compressed in the receiving trough 2 itself by means of the die 6 using the receptacle 3 of the holding mold 4 as an abutment to form a compact tablet 7. Fig. 2 does not yet show the final state of the tablet 7, the pressing step has not yet taken place. In Fig. 1, the tablets 7 are clearly visible in the receiving wells 2 of the strip-like film 1.

After completion of the above-mentioned process step, the film 1 is removed with the located in the receiving trough 2 tablets 7 of the holding mold 4 and fed to further handling stages. Before, simultaneously with or After this process step, the receiving trough 2 is closed on the open side by attaching a closing foil 8, as indicated for example in FIG. 1 on the very left for better illustration. Instead of a closing film 8, which can be used particularly useful in many receiving troughs 2 a longer film strip 1, also cover or cover strips can be used.

The film 1 can be provided with the receiving troughs 2 continuously by means of a roller arrangement or sections by means of a flat thermoforming tool. It is assumed here for this method that the film is already provided with receiving troughs. Corresponding methods are widely known from the prior art for blister packs.

Fig. 3 shows schematically the structure of a device with which another method for producing a filled with an active agent in tablet form packaging is feasible. In this process claimed here the following process steps are provided:

A packaging-forming film 1 is placed on a holding mold 4 with at least one receptacle 3 forming a receiving trough, in the illustrated exemplary embodiment again four juxtaposed receptacles 3. Before or at the same time as the above-explained method step, a specific amount of the not yet compressed active agent (premix) is filled and preformed in a premix holder 9 associated with a holder 3 of the holding mold 4 in a mold 4 associated with the mold 4. 3 shows the preformed premix stocks in the premix holders 9 of the mold 6 above.

By arrows is arranged that the mold is closed altogether. In this case, the preformed active agent is pressed out of the Premixaufnahme 9 on the packaging film 1 and this together, deforming them to a receiving trough 2 deforming in the receptacle 3 of the holding mold 4 and then using the recording 3 of the holding mold 4 as an abutment to a compact Tablet pressed. Thus, after carrying out this method step, it ends practically in a representation of the holding mold 4, which corresponds to FIG. 2.

In this method, the deformation of the film 1 is performed in the manner of a deep drawing operation simultaneously with the pressing process, which significantly simplifies the production.

Incidentally, in the method explained above, the further method steps are identical to the known method explained above with reference to FIG. 2.

FIG. 3 shows, for the method implemented here, that the ejection of the preformed active agent agent from the premix holder 9 can take place by means of a punch 10 displaceably arranged in the mold 6. The mechanical drive source for the punch 10 is not shown in Fig. 3. Rather, a pneumatic drive source is indicated, namely, such that the displacement of the punch 10 and of the preformed agent-agent cake from the premix holder 9 takes place by means of compressed-air supply via a compressed-air system 11.

The illustrated and so far preferred embodiment also shows that the deformation of the film 1 in the receptacles 3 of the holding mold 4 is supported by air suction from the receptacles 3 of the holding mold 4 by means of the illustrated suction system 12. At least the holding mold 4 should be provided on the receptacles 3 with air outlets to ensure a rear ventilation of the receptacles 3 when performing the deep-drawing and pressing process.

The illustrated embodiment shows that the method steps of the two methods explained here are each carried out quasi-static on a film section. Alternatively, however, it is also possible, in particular in the case of the method explained with reference to FIG. 3, to carry out the method steps on a continuous film 1 by means of roller arrangements, revolving belt arrangements or partially running tools. Such methods are known in the art of tablet manufacturing, especially in conjunction with eccentric presses and rotary presses. However, the quasi-static design is particularly simple tool technology.

Typical pressing forces for tablets with an area of 10 to 15 cm ² are between 10 and 60 kN.

Fig. 4 shows that one can form a plurality of receiving wells 2 in the film 1 next to each other and / or in a row and each can simultaneously fill with detergent.

Conveniently, plastic films, in particular PE films or PVC films, are used as packaging-forming films. As closing foils 9, on the other hand, wafer-thin metal foils are used which typically allow push-through or peel-off. The connection of the closing film 8 with the packaging-forming film 1 is carried out by conventional joining techniques such as gluing, welding, high-frequency joining techniques, etc.

In the packaging-forming films 1 and the closing films 8, made as plastic films, it is generally possible to distinguish between water-insoluble and water-soluble films. Both types of foil can be used equally. Water-insoluble films are produced, for example, from PVC, PE, PP, and mixtures of PE and polystyrene. Water-soluble films are prepared, for example, from polyvinyl alcohol, starch, cellulose, gelatin (with corresponding reactive internals). Of course, in particular the above-mentioned metal foil, that is, in particular an aluminum foil, comes into consideration as the closing foil 9 as a water-insoluble foil.

The use of water-soluble films for a filled with an agent agent packaging has also been known for some time from the prior art (WO 89/04282 A1). The packaging of different, water-soluble active agent agents in a water-soluble packaging for the purpose of portioning and handling can be taken from this prior art.

Fig. 6 indicates an additional packaging variant such that an additional child safety in the form of a comprehensive, additional cap 13 is provided, from which the sales unit with multiple tablets 7 can not be pulled out easily, but only with additional handling in the arrow direction. Such a cap 13 also provides a convenient area for advertising, instructions for use or company logo.

It is also possible to connect the closing foil 8 or the lid to the package-forming foil 1 in a particularly child-resistant manner, for example by the fact that the realizable tearing forces are dimensioned so high that a toddler can not apply them.

A particular measure can be made for example by the fact that the closing film 8 is a double-layered film, between the layers of which an additional body of an active ingredient is protected housed protected. For example, this additional body may be a fragrant lens, which may not come into contact with the tablet 7 of the active agent in order not to impair the shelf life, but is readily emptied together with the tablet 7 from the packaging. Corresponding additional bodies could also concern bleaching agents or enzyme components.

The illustrated embodiments make it clear that in the receiving wells 2 filled with active ingredient tablets 7 and provided with closing film 8 or lids packaging-forming films 1 in commercial units - sales units - cut, possibly even isolated (Fig. 5). FIG. 7 shows, for example, a multipack with one double receiving trough 2. In the exemplary embodiment of FIG. 5, individual receiving troughs 2 are respectively realized.

Fig. 5 further shows that to form a sales unit 14 here several packages have been used in a cardboard consisting of corresponding receiving openings carrier 15. The carrier 15 forms the sales-active Oberfiläche the sales unit 14 of Fig. 4, which can be hung with a euro hanger in sales walls.

FIGS. 4 and 6 show exemplary embodiments of sales units which contain tablets 7 of different active agent agents. For purposes of laundry care, a sales unit shown in FIG. 4 may contain, for example, two rows of detergent, a series of bleaches and a series of colorants or a series of enzyme detergents. This flexibility in the placement of sales units 14 results from the individual intake of the tablets 7 in the individual receiving wells 2.

By the method described by direct compression of the active agent agent premix in the receiving trough 2 and the recording of the 3 Holding form 4, it is possible to use a formulation for the active agent, which works without or with only a few shape-stabilizing components. The tablet 7 is right from the outset in the receiving trough 2 of the film 1, it is not handled by itself in the manufacturing process of the package.

Moreover, for the advantages of the method according to the invention, reference is also made to the explanations in the general part of the description.

4 and 5 make clear in a particularly preferred embodiment, the final state of a salable, filled packaging. This consists of a provided with at least one molded receiving trough 2 packaging film forming 1 and a receiving trough 2 closing closing film 8 (or a corresponding cover). In the receiving trough 2 is airtight enclosed the active agent tablet 7th

The realization of the direct compression of the tablet 7 in the receiving trough 2 causes the bottom of the receiving trough 2 located edge of the tablet 7 corresponds in its edge contour to the edge profile of the receiving trough 2. This is in practice not as sharp-edged as indicated in Fig. 5, but in this area quite rounded with a practical radius. By pressing in the receiving trough 2 with the receptacle 3 of the holding mold 4 as an abutment, the edge of the tablet 7 is adapted accordingly.

The pressing in the receiving trough 2 also has the consequence that the tablet 7 rests substantially on the entire circumference of the circumferential inner wall of the receiving trough 2. This too is not shown in FIG. 5 in order to be able to differentiate the packaging-forming film 1 from the edge of the tablet 7 in terms of character.

Finally, a packaging of the type in question is usually so realized that the bottom of the receiving trough 2 located edge of the tablet 7 has a different contour than the side facing the open side of the receiving trough 2 edge of the tablet 7, in particular more rounded than that , The pressing tool, in a preferred embodiment, in particular the punch 10 on the mold 6, immersed in the receptacle 3 and leads to a sharp-edged, possibly a slight circumferential ridge pointing Edge contour of the tablet 7. This does not show the bottom of the receiving trough 2 located edge of the tablet 7.

The realization of separate receiving wells 2 for receiving in each case a tablet 7 of Wirkstöffmittels are in practice a variety of ways of designing the active agent tablets 7, in particular detergent tablets or detergent tablets.

In particular, there are many possibilities for the design of the packaging.

In the prior art, it is usually the case that, as already described in the introduction, the film 1 with closing foil 8 is disposed of in the waste after consumption of the tablets 7 contained in the packaging.

After a first proposal that is now changed such that the packaging-forming film 1 and the closing film 8 and the lid made of water-soluble materials, in particular water-soluble or water-soluble plastics and that for the use of the active ingredient, in particular the cleaning agent in a water bath the entire packaging is fed to the water bath. Thus, the problem of waste from the packaging for the consumer is solved without problems, only when using other materials in an overall packaging (sales unit), for example, when using the previously mentioned carrier 15 made of cardboard, you have to dispose of it in waste paper.

In this connection, reference may be made to the previously given references to water-insoluble and water-soluble films.

A water-soluble packaging film 1 or closing film 8 may have the problem that it shows during prolonged storage already such a strong water absorption from the ambient air that the protective effect decreases. Therefore, it may be advisable to additionally provide that the packaging is enclosed for transport and storage with a substantially water vapor-tight thin film. This film can be designed solely for their task of water vapor shield out, they must not endure strong mechanical stresses, because yes, the packaging film 1 with the closing film 8 is used.

For particularly delayed drug delivery, it is sometimes useful to provide the drug agent with a coating. The described solution forms the possibility that the packaging-forming film 1 and the closing film 8 have material properties corresponding to the intended use of the active agent means coatings.

An alternative, advantageous embodiment of a package of the type in question can also be designed so that the tablet 7 is constructed of several layers of at least two layers 20, 21 of identical or different active agent agents and at least one layer 22 of a neutral release agent.

Fig. 8 shows an example of such a modified tablet 7 which can be used in a single or multiple package. By introducing a neutral layer 22 of a release agent, the active ingredient components in the other two layers 20, 21 are separated from each other. Incompatible drug components can thus be processed in one and the same tablet 7. Due to the stability of the packaging, this can be realized particularly well, because the boundary layers between the individual layers of a multilayer tablet 7 in this package are not exposed to major forces. The packaging holds, in particular in realization of the above-described manufacturing method, the tablet 7 also tightly enclosed and dimensionally stable.

Furthermore, it is possible for marking substances suitable for product identification to be embedded or contained in the layers 20, 21, 22, in particular in the layer 22 of the release agent.

A further alternative is for the design of the tablet 7 in that in the tablet 7 inside or to the upper or lower outer surface towards a solid, pasty or coated with protective sheath, in particular gel coat liquid additional body is provided. Even so you can realize different agents in a tablet 7.

Finally, the package offers yet another advantageous design option, which is characterized in that the Schüeßfolie 8 is designed to be double-layered and that between the layers of the closing film 8 a Additional body of an active agent is arranged. This also allows you to accommodate an additional, possibly incompatible agent agent of the tablet 7 separately in the package and still ensure that the dosage at the point of use is carried out simultaneously with the tablet 7. For example, it is possible to add a fragrance lens, enzymes or a bleaching component in the washing process.

The double-layered design of the closing film 8 may have special significance in time-delayed cleaning processes, if a water-soluble closing film 8 and packaging-forming film 1 are provided. First of all, the outer layer of the closing film 8 can then be dissolved, so that the active agent agent located between the layers is released. With a time delay, the inner layer of the closing film 8 and the packaging-forming film 1 itself is decomposed, which then release the tablet 7 with the further active agent agent in a time-delayed manner. Such a delayed release of active ingredient is not only used in laundry care, but also, for example, in a toilet bowl cleaner.

As has already been mentioned above, applies to the described larger package, that it has a plurality of receiving wells 2 and in the receiving wells 2 tablets 7 incompatible storable drug agent are included and / or that several packages in a cardboard consisting, corresponding receiving openings having carrier 15 are used.
