Abstract

The present invention relates to an application package and a method for its production. The application package includes a bottom portion obtained from a multilayer film and a cover.

Description

Technical Field

[0001] The invention relates to an application package for preferably liquid pharmaceutical products and to a method for producing and filling an application package and to the use of a plastic sheet for producing an application package.

[0002] The application package is produced in particular by thermoforming. Thermoforming is a process in which a plastic sheet, in particular a film or foil, is heated to a bendable temperature and then formed into a specific shape in a mold. Furthermore, the plastic sheet is preferably trimmed after forming in the mold.

[0003] The administration package is in particular a package for a liquid pharmaceutical product, which contains the product or stores the product therein and can also be used to administer the product to a patient. The package is in particular a pipette or can be used as or transformed into a pipette.

[0004] The pharmaceutical preparation is preferably a liquid and / or a preparation to be applied to the skin and / or fur of a patient, preferably a domestic animal such as a cat or dog. Background Art

[0005] EP 2 998 098 A1 and EP 2 998 099 A1 relate to a method for producing and filling an application package for a liquid pharmaceutical product. The package is produced by a thermoforming process, wherein a deep-drawn film is heated in order to plasticize the film at least in a subregion, the plasticized region is deep-drawn into a molding tool to form a cavity for the product and a sleeve-like application channel leading to the cavity, the product is introduced into the cavity, and the filled deep-drawn film is covered with a covering film in order to close the cavity and the application channel. In an end region, the application channel has a slit or groove forming a predetermined breaking zone, at which the tip of the application channel can be broken in order to open the application package. The predetermined breaking zone is produced before the deep-drawn film is heated. The deep-drawn film is a laminated composite film having a layer of polypropylene (PP) and a layer of acrylonitrile-methacrylate copolymer (AMAB), and the slit or groove is produced by cutting through the PP layer.

[0006] The methods disclosed in EP 2 998 098 A1 and EP 2 998 099 A1 have several disadvantages.

[0007] Firstly, in order to avoid any undesired interaction of solvents or active ingredients of the pharmaceutical product with the packaging, only specific combinations of plastic films can be used for the cover film and the deep-drawn film. The same applies to the breaking zone: only specific material combinations can be used to ensure that a clean break at the breaking zone and a usable pipette ready for application can be obtained reproducibly. Unfortunately, the branded pipettes mentioned in EP 2 998 098 A1 or EP 2 998 099 A1, respectively, are not suitable for use in the packaging. The specific acrylonitrile methacrylate copolymer (AMAB) distributed is no longer available.

[0008] Furthermore, besides the thermoforming step for forming the cavities and the application channels, the creation of the recesses also requires an additional step.

[0009] Finally, the method of producing a predetermined breaking zone by cutting through the PP layer does not work when the film has a composition different from that described and / or the set-up of a system for cutting is more complex.

[0010] Therefore, there is a need for a new material combination that enables the use of such a single-use package for liquid pharmaceutical products.

[0011] U.S. Patent Application US 2012 / 0265159 A1 describes a device for storing and dispensing a medicament, and more specifically describes a device that can be used to dispense a parasiticidal medicament to the skin of an animal. Particular attention is paid to the configuration of a packaging device, which is designed so that it includes a wall or second layer coupled to a substrate or first layer, wherein the substrate and the wall define a medicament reservoir. At least a portion of the wall or second layer is configured to deform when the wall is actuated to reduce a volume of the medicament reservoir, so as to facilitate dispensing a medicament from the device.

[0012] In view of the materials that may be included in the first or second layer of the device, it is only provided that the first and / or second layers, as well as any other layers, walls and structures contained within any described drug container, may be composed of any suitable material. Such materials may be selected to minimize interaction with the drug, may be composed of a substantially inert and / or flexible polymer, or may be composed of a polymer having a particular hardness. However, the material is not related to a possible opening mechanism of the described device, and expressly, is not intended to address a potential or all possible uses in the context of designing a predetermined rupture zone.

[0013] German utility model DE 201 16 341 U1 describes a polyolefin multilayer film. Such films are particularly suitable for use with perishable foods such as fresh meat or sausages. Thus, the multilayer plastic film comprises at least two plastic layers, wherein at least one layer comprises a mixture of at least one semicrystalline polyolefin and more than 5% by weight of at least one amorphous polyolefin, and at least one further layer comprises a material having an oxygen barrier effect. The film is expected to be characterized by a uniform wall distribution after thermoforming, good thermoformability with low shrinkage after thermoforming, good puncture resistance under static and / or dynamic loads, good barrier properties for water vapor and oxygen, and consistent mechanical properties independent of hygroscopicity.

[0014] However, the document does not involve or provide a basis for the potential applicability of the multilayer film for medical applications, which meets specific application requirements that cannot be equated with material requirements for food packaging. Furthermore, the film is described as being particularly resistant to puncture, even under mechanical strain. This material property does not seem to be suitable for an application package that is intended to be opened by breaking or opening a specific part of the package.

[0015] International application WO 2018 / 132113 A1 describes a blister package for solid drugs (i.e., tablets). These are formed by a multilayer structure comprising, in the following order: a first passive moisture barrier layer; a second passive moisture barrier layer; a first active moisture barrier layer comprising a first hygroscopic composition and a cyclic olefin copolymer; and a third passive moisture barrier layer, wherein the first, second and third passive moisture barrier layers and the first active moisture barrier layer are continuous, discontinuous or a combination thereof.

[0016] It is mentioned that effective post-treatment is achieved by appropriately modifying the active moisture barrier with an elastomer and also by surrounding the active moisture barrier with a passive moisture barrier having a modulus equivalent to or lower than that of the active moisture barrier. In this respect, appropriate modification means reducing the hardness of the material or increasing flexibility and elasticity, respectively. It can be inferred from this that the described material is not suitable for an application package intended to be opened by breaking or opening a specific part of the package, but on the contrary, that is, no hardness or breakability, which constitutes the focus of WO 2018 / 132113 A1.

[0017] Therefore, the prior art lacks a suitable alternative which can be used as a replacement for one of the materials described in EP 2 998 099 A1 or EP 2 998 099 A1, respectively. In this respect, it is expressly stated that the aspect of the controlled breakability of the polymeric material remains essentially unaffected.

[0018] Furthermore, there is a need for an efficient method for producing an application package which allows a predetermined breaking zone to be reproducibly formed in the application package. Summary of the invention

[0019] It is therefore an object of the present invention to provide a new material combination which protects the active ingredients of a liquid pharmaceutical product from environmental influences and does not exhibit any undesirable chemical interactions with the solvent or the active ingredients of the liquid pharmaceutical product and furthermore prevents the liquid pharmaceutical product or its ingredients from leaking out of the packaging.

[0020] Furthermore, it is an object of the invention to provide a material combination which makes it possible to obtain a distinct breaking zone in the package which allows the package to be opened precisely in a predetermined manner.

[0021] Finally, it is an object of the present invention to provide an enhanced method for producing an application package.

[0022] In order to solve the above-mentioned purpose, the present invention proposes an application package as described in Technical Solution 1; in addition, the advantageous implementation method is the target of each of the attached technical solutions.

[0023] In addition, to solve the above-mentioned purpose, the present invention proposes a method such as technical solution 17; a further advantageous implementation method is the target object of the attached technical solution.

[0024] In addition, to solve the above-mentioned purpose, the present invention proposes a use such as technical solution 21; a further advantageous implementation method is the target object of the attached technical solution.

[0025] It goes without saying that in order to avoid unnecessary repetition, the following description only relates to one aspect of the present invention, and of course correspondingly the specific features, characteristics, embodiments and advantages or the like described with respect to other aspects of the present invention do not need to be explicitly mentioned.

[0026] Furthermore, this applies to the fact that all values ​​or parameters or the like mentioned hereinafter can in principle be determined or measured by standardized or explicitly stated determination methods or by determination methods with which the person skilled in the art is familiar.

[0027] Furthermore, it goes without saying that all percentages relating to weights or amounts are selected by the person skilled in the art so that the totals result in 100%.

[0028] With this proviso in mind, the present invention will be described in more detail below.

[0029] Therefore, according to a first aspect of the invention, the object of the invention is an administration package for a preferably liquid pharmaceutical product,

[0030] wherein the administration package has a bottom portion having a cavity for receiving the pharmaceutical product and a rim surrounding the cavity,

[0031] wherein the administration package has a cover covering and completely enclosing the cavity,

[0032] wherein the application package (in particular the bottom portion) has a predetermined breaking zone for opening the application package by breaking the predetermined breaking zone,

[0033] wherein the bottom portion is formed by a plastic sheet in the form of a multilayer film and wherein the cover is a cover sheet in the form of a multilayer film,

[0034] in

[0035] The plastic sheet of the bottom part includes at least 5 layers:

[0036] an outer thermoformable layer,

[0037] a cyclic olefin copolymer (COC) layer,

[0038] an inner thermoformable layer,

[0039] a barrier layer, preferably a barrier layer to oxygen and / or chemicals,

[0040] a sealing layer, preferably a heat sealing layer,

[0041] wherein the cyclic olefin copolymer layer is disposed between the outer thermoformable layer and the inner thermoformable layer and wherein the barrier layer is disposed between the sealant layer and the inner thermoformable layer.

[0042] As the applicant has surprisingly discovered, this particular modular combination allows to obtain deep-drawn packages which are suitable for single-use as breakable packages for the administration of liquid pharmaceutical products. In particular, the material combination allows to safely enclose a liquid drug in a package without any undesirable interactions between the package and the components of the liquid pharmaceutical product, in particular the active ingredient or the solvent, respectively. Furthermore, substances from the environment, in particular oxygen and / or water vapor, cannot penetrate the package and degrade the liquid pharmaceutical product. The above layer combination allows to replace the Barex films used hitherto and the layer structure according to the invention has a thickness similar to that of known multilayer Barex films.

[0043] Compared to the Barex-containing multilayer films used in the prior art, thermoformable deep-drawing films based on cyclic olefin copolymers (COC) surprisingly exhibit comparable or even enhanced chemical and mechanical properties. The cyclic olefin copolymer (COC) layer is the main layer of the multilayer plastic sheet forming the bottom part of the application package of the present invention. The cyclic olefin copolymer (COC) layer comprises COC or consists of COC, preferably consists of COC. Cyclic olefin copolymers (COC) are amorphous polymers obtained by copolymerization of cyclic monomers such as 8,9,10-triazacyclopentene (norbornene) or 1,2,3,4,4a,5,8,8a-octahydro-1,4:5,8-dimethylnaphthalene (tetracyclododecene) with ethylene. Particularly preferably, copolymers of ethylene and norbornene are used with the present invention.

[0044] COC is rigid and thus can provide structural integrity and hardness to the inventive application package, but is also brittle and thus can be manufactured into a package with a predetermined breaking zone for opening the package. In addition, COC has good moisture barrier properties, especially when used with a high layer thickness. In addition, COC has good chemical resistance and barrier properties to polar solvents, and is resistant to acids and bases.

[0045] A further advantage of COCs is that they can be of high purity so that solvents or active ingredients contained in a package cannot extract impurities.

[0046] As depicted above, the COC layer is disposed between two thermoformable layers.

[0047] According to the present invention, the outer thermoformable layer comprises or consists of a polymer selected from the group consisting of polystyrene (PS), polyvinyl chloride (PVC), amorphous polyethylene terephthalate (APET), ethylene butyl acrylate (EBA), ethylene vinyl alcohol (EVA), polypropylene (PP), polyethylene (PE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE) and mixtures thereof.

[0048] The outer thermoformable layer is also usually applied to the outer surface of the package, especially to the outer surface of the bottom portion of the package. Compared with the COC layer, the outer thermoformable layer is usually less rigid and less brittle. It protects the COC layer from damage and provides a better handleability and enhanced thermoforming properties to the multilayer film.

[0049] According to a preferred embodiment of the present invention, the polymer of the outer thermoformable layer is selected from the group consisting of polypropylene (PP), polyethylene (PE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE) or mixtures thereof.

[0050] The best results are obtained if the polymer of the outer thermoformable layer is polypropylene (PP). Polypropylene has a good compatibility with COC. Furthermore, the rigidity and brittleness of polypropylene are much lower than COC and therefore, an outer thermoformable layer of PP improves the thermoforming properties of the COC layer and protects the brittle COC layer from damage during handling, storage or application. Furthermore, the PP layer enhances the processability of the multilayer film, in particular the COC layer. In particular, a PP layer provides enhanced flexibility to the COC layer and the plastic sheet of the bottom portion of the application package of the invention.

[0051] The inner thermoformable layer typically comprises or consists of a polymer selected from the group consisting of polystyrene (PS), polyvinyl chloride (PVC), amorphous polyethylene terephthalate (APET), ethylene butyl acrylate (EBA), ethylene vinyl alcohol (EVA), polypropylene (PP), polyethylene (PE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE) and mixtures thereof.

[0052] According to the invention, it is preferred if the polymer of the inner thermoformable layer is selected from the group consisting of polypropylene (PP), polyethylene (PE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE) or mixtures thereof. Particularly good results are obtained if the polymer is polypropylene (PP).

[0053] According to the invention, if a plastic film or a layer comprises a specific polymer or consists of a specific polymer, it means that the film or layer comprises or consists of this polymer as the polymeric material of the film or layer, respectively. However, further components (e.g. fillers and additives) may also be present in the film or layer, respectively.

[0054] According to the invention, it is preferred if the outer thermoformable layer and the inner thermoformable layer comprise or consist of, preferably consist of, the same polymer(s).

[0055] Preferably, the outer thermoformable layer and the inner thermoformable layer comprise or consist of the same material (i.e. polymer). In this respect, it is particularly preferred if the outer thermoformable layer and the inner thermoformable layer comprise or consist of polypropylene (PP), preferably consist of polypropylene (PP). If a COC layer is arranged between two PP layers, the processability of the resulting multilayer film is particularly good. In particular, on the one hand, the rigidity of COC is reduced by PP, but on the other hand, the brittleness of COC still allows the production of predetermined distinct fracture zones in the package.

[0056] Regarding the barrier layer, according to the present invention, it is preferred if the barrier layer comprises a polymer selected from the group consisting of ethylene vinyl alcohol (EVOH), ethylene vinyl alcohol (EVA), polyvinylidene chloride (PVDC), polychlorotrifluoroethylene (PCTFE), polyethylene terephthalate (PET), amorphous polyethylene terephthalate (APET), polyethylene naphthalate (PEN), ethyl methacrylate (EMA), ethylene butyl acrylate (EBA), ethylene ethyl acrylate (EEA), poly(methyl methacrylate) (PMMA), ethylene / methyl methacrylate (EMMA), ethylene acrylic acid copolymer (EAA), ethylene methacrylic acid copolymer (EMAA), polyacrylonitrile (PAN) or a mixture thereof.

[0057] According to the invention, it is preferred if the barrier layer comprises or consists of a polymer selected from the group consisting of ethylene vinyl alcohol (EVOH), polyvinylidene chloride (PVDC), polychlorotrifluoroethylene (PCTFE) and mixtures thereof, preferably consists of said polymer.

[0058] According to a particularly preferred embodiment of the present invention, the polymer of the barrier layer comprises or consists of ethylene vinyl alcohol (EVOH), preferably consists of ethylene vinyl alcohol (EVOH). In particular, ethylene vinyl alcohol provides good barrier properties against oxygen and against solvents and other chemicals or components of pharmaceutical products.

[0059] Regarding the sealing layer, according to the present invention, it is preferred if the sealing layer comprises or consists of a polymer selected from the group consisting of polypropylene (PP), propylene copolymer (CoPP), polypropylene terpolymer (ter-PP), polyethylene (PE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), metallocene linear low density polyethylene (mLLDPE), very low density polyethylene (VLDPE), ionomers of acid copolymers, ethylene acrylic acid copolymer (EAA), ethylene methacrylic acid copolymer (EMAA), ethyl methacrylate (EMA), ethylene vinyl alcohol (EVA) or mixtures thereof.

[0060] According to a preferred embodiment of the present invention, the polymer of the sealing layer is selected from the group consisting of polypropylene (PP), propylene copolymer (CoPP), polypropylene terpolymer (ter-PP), polyethylene (PE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), metallocene linear low density polyethylene (mLLDPE), very low density polyethylene (VLDPE) or mixtures thereof. Particularly good results are obtained if the polymer is selected from the group consisting of polypropylene (PP), polyethylene (PE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), metallocene linear low density polyethylene (mLLDPE), very low density polyethylene (VLDPE) or mixtures thereof.

[0061] According to the invention, it is particularly preferred if the sealing layer comprises or consists of polyethylene (PE), preferably consists of polyethylene (PE). Polyethylene is a common material for sealing layers, has good water vapor barrier properties and is compatible with many barrier materials (especially EVOH).

[0062] As already described above, the COC layer provides structural integrity to the application package.Therefore, the COC layer is usually the thickest layer of the multilayer plastic sheet forming the bottom portion of the application package of the present invention.

[0063] According to the invention, it is preferred if the cycloolefin copolymer (COC) layer has a thickness of at least 200 μm, in particular 250 μm, preferably 300 μm, more preferably 350 μm, particularly preferably 360 μm.

[0064] Likewise, it is preferred if the cycloolefin copolymer layer has a thickness of at most 600 μm, in particular 500 μm, preferably 450 μm, more preferably 400 μm, particularly preferably 390 μm.

[0065] Furthermore, good results are obtained if the cycloolefin copolymer layer has a thickness in the range from 200 μm to 600 μm, in particular 250 μm to 500 μm, preferably 300 μm to 450 μm, more preferably 350 μm to 400 μm, particularly preferably 360 μm to 390 μm.

[0066] The COC layer having the above thickness exhibits good water vapor barrier properties and is able to provide structural integrity and rigidity to the application package.

[0067] Regarding the outer and inner thermoformable layers, it is preferred if the outer and / or inner thermoformable layers have a thickness of at least 10 μm, in particular 12 μm, preferably 15 μm, more preferably 18 μm, particularly preferably 20 μm.

[0068] Likewise, it is preferred according to the invention if the outer thermoformable layer and / or the inner thermoformable layer has a thickness of at most 40 μm, in particular 35 μm, preferably 30 μm, more preferably 27 μm, particularly preferably 25 μm.

[0069] According to a preferred embodiment of the present invention, the outer thermoformable layer and / or the inner thermoformable layer has a thickness in the range from 10 μm to 40 μm, in particular 12 μm to 35 μm, preferably 15 μm to 30 μm, more preferably 18 μm to 27 μm, particularly preferably 20 μm to 25 μm.

[0070] According to the present invention, it is particularly preferred if both the outer thermoformable layer and the inner thermoformable layer have a thickness within the above range. Thus, these relatively thin thermoformable layers can provide enhanced flexibility to the COC layer and enhance the handleability of the multilayer plastic sheet of the bottom portion used according to the present invention.

[0071] According to the invention, it is preferred if the thickness of the cycloolefin copolymer layer to the thickness of the outer thermoformable layer and / or the thickness of the inner thermoformable layer is in the range from 5:1 to 30:1, in particular 7:1 to 25:1, preferably 10:1 to 22:1, more preferably 13:1 to 20:1, particularly preferably 15:1 to 18:1.

[0072] With regard to the barrier layer, it is preferred according to the invention if the barrier layer has a thickness of at least 2 μm, in particular 5 μm, preferably 7 μm.

[0073] Furthermore, it is likewise preferred if the barrier layer has a thickness of at most 20 μm, in particular 15 μm, preferably 12 μm.

[0074] According to the invention, it is preferred if the barrier layer has a thickness in the range from 2 μm to 20 μm, in particular 5 μm to 15 μm, preferably 7 μm to 12 μm.

[0075] Therefore, according to the present invention, it is preferred to use a relatively thin barrier layer.

[0076] According to a preferred embodiment of the present invention, the sealing layer has a thickness of at least 10 μm, in particular 15 μm, preferably 17 μm, more preferably 20 μm, particularly preferably 22 μm.

[0077] Furthermore, the sealing layer generally has a thickness of at most 50 μm, in particular 40 μm, preferably 35 μm, more preferably 30 μm, particularly preferably 27 μm.

[0079] According to a preferred embodiment of the invention, the plastic sheet to which the bottom portion of the packaging is applied comprises an intermediate layer.

[0080] If the plastic sheet of the bottom portion of the application package comprises an intermediate layer, the intermediate layer is preferably arranged between the inner thermoformable layer and the barrier layer. An intermediate layer between the barrier layer and the inner thermoformable layer enhances the compatibility of the barrier layer with the inner thermoformable layer.

[0081] If the plastic sheet of the main body part includes an intermediate layer, the intermediate layer generally includes a polymer selected from the group consisting of the following, or consists of the polymer, preferably consists of the polymer: polypropylene (PP), propylene copolymer (CoPP), polypropylene terpolymer (ter-PP), polyethylene (PE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), metallocene linear low-density polyethylene (mLLDPE), very low-density polyethylene (VLDPE), ionomers of acid copolymers, ethylene acrylic acid copolymers (EAA), ethylene methacrylic acid copolymers (EMAA), ethyl methacrylate (EMA), ethylene vinyl alcohol (EVA) or mixtures thereof.

[0098] In this respect, particularly good results are obtained if the outer thermoformable layer and the inner thermoformable layer comprise or consist of a polyolefin, in particular polypropylene (PP), in particular consist of a polyolefin, in particular polypropylene (PP).

A direct bond means that the layers are in direct contact with one another (e.g., by coextrusion), or the layers are bonded directly together using a tie layer or an adhesive layer. An indirect bond means that a further plastic film or metal foil is arranged between the individual layers.

[0100] Preferably, the layers are directly bonded to each other, as already stated.

[0101] With respect to this particular embodiment, all advantages, particularities, and features described above in conjunction with the other embodiments also apply.

[0113] The plastic sheet of the bottom portion having the above thickness can provide structural integrity to the package and has a layer thickness within the range of Barex films used in the prior art.

[0114] According to a specific and preferred embodiment of the present invention, the plastic sheet of the bottom portion further comprises a tie layer and / or an adhesive layer.

[0115] Tie layers and adhesive layers are very thin layers, usually with a layer thickness of 2 to 20 μm, preferably 5 to 15 μm, which are used to join layers of multilayer plastic sheets together. According to the invention, if an adhesive layer is used, the adhesive is usually a solvent-based or water-based polyurethane adhesive. The tie layer usually consists of an adhesive resin.

[0116] According to a preferred embodiment of the present invention, the plastic sheet of the bottom portion comprises a tie layer or an adhesive layer between the polymer layers.

[0117] As described above, the application package according to the present invention comprises a cover consisting of a cover sheet. Typically, the cover sheet is a multilayer film comprising and consisting of the following layers:

[0123] The first barrier layer is disposed between the protection layer and the middle layer, and the second barrier layer is disposed between the middle layer and the sealing layer.

[0124] The layers of the cover sheet can be in direct or indirect contact with each other. A direct contact means that the layers of the cover sheet are directly bonded to each other, for example, by coextrusion or by an adhesive layer or a tie layer. An indirect contact means that a further polymer layer or a metal foil is arranged between at least two individual layers of the cover sheet.

[0125] In this context, if the abovementioned layers follow one another, ie according to a preferred embodiment of the present invention, the abovementioned layers are formed continuously or sequentially and / or are not separated from one another by any further intermediate layers than the mentioned intermediate layers.

[0126] The multilayer plastic sheet forming the bottom portion of the application package of the present invention is a relatively thick plastic sheet that provides form and structural integrity to the application package, while the cover sheet is a relatively thin multilayer film.

[0127] Typically, the cover sheet has a thickness of at least 50 μm, in particular 70 μm, preferably 80 μm, more preferably 90 μm, particularly preferably 95 μm.

[0128] Likewise, the cover sheet has a thickness of at most 200 μm, in particular 180 μm, preferably 150 μm, more preferably 140 μm, particularly preferably 130 μm.

[0130] Concerning the protective layer of the cover sheet, good results are obtained if the protective layer comprises or consists of a polymer selected from the group consisting of polyethylene terephthalate (PET), polyamide (PA), polyvinylidene fluoride (PVDF) and mixtures thereof.

[0131] The protective layer provides protection for the administration package and the liquid pharmaceutical composition or product respectively contained in the administration package from physical damage. In addition, the protective layer is preferably also a printable layer.

[0138] The intermediate layer of the cover sheet mainly enhances the compatibility between the first barrier layer and the further layers of the cover sheet, in particular the second barrier layer. The material of the intermediate layer can be selected from any suitable material, as long as it is compatible with any adjacent layer. However, good results are obtained if the intermediate layer comprises or consists of a polymer selected from the group consisting of polypropylene (PP), propylene copolymer (CoPP), polypropylene terpolymer (ter-PP), polyethylene (PE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), metallocene linear low density polyethylene (mLLDPE), very low density polyethylene (VLDPE), ionomers of acid copolymers, ethylene acrylic acid copolymers (EAA), ethylene methacrylic acid copolymers (EMAA), ethyl methacrylate (EMA), ethylene vinyl alcohol (EVA) or mixtures thereof.

[0144] As for the second barrier layer, the second barrier layer is mainly a barrier layer for chemicals and should prevent any undesirable interaction between the liquid pharmaceutical composition or product and the package, respectively. Therefore, the second barrier layer of the cover sheet usually comprises the same material(s) as the barrier layer of the multilayer plastic sheet of the bottom part of the application package of the present invention, or consists of such material(s), preferably consists of such material(s).

[0145] The second barrier layer generally comprises or consists of a polymer selected from the group consisting of ethylene vinyl alcohol (EVOH), ethylene vinyl alcohol (EVA), polyvinylidene chloride (PVDC), polychlorotrifluoroethylene (PCTFE), polyethylene terephthalate (PET), amorphous polyethylene terephthalate (APET), polyethylene naphthalate (PEN), ethyl methacrylate (EMA), ethylene butyl acrylate (EBA), ethylene ethyl acrylate (EEA), poly(methyl methacrylate) (PMMA), ethylene / methyl methacrylate (EMMA), ethylene acrylic acid copolymer (EAA), ethylene methacrylic acid copolymer (EMAA), polyacrylonitrile (PAN) or a mixture thereof.

The application package 1 is preferably openable at the predetermined breaking zone 9 and / or by breaking the application package 1 , in particular the bottom portion 3 , along the predetermined breaking zone 9 .

[0281] In particular, the application package 1 can be opened by folding and / or bending along the predetermined breaking zone 9 .

[0282] The predetermined breaking zone 9 is preferably produced by hot forming or deep drawing, in particular at the same time as the hot forming or deep drawing of the bottom part 3 or in the same step and / or using the same molding tool. Figure 4 and Figures 19 to 22 Explain this in more detail.

[0283] The predetermined breaking zone 9 preferably passes through the cavity 5 (in particular the application channel 7 ) and / or is arranged in the region of the cavity 5 (in particular the application channel 7 ).

[0284] The break zone 9 may be provided only in the region of the cavity 5 or the application channel 7. In other words, the edge 8 may be at least substantially free of the break zone 9. Figures 9 to 11 This is explained in more detail. Alternatively, the breaking zone 9 can extend at least substantially along (the width of) the entire application package 1 and / or can be provided in the region of the cavity 5 (in particular the application channel 7 and the edge 8), such as for example in Figure 1 and Fig.13 and will be explained in more detail later.

[0285] The predetermined breaking zone 9 preferably extends transversely, in particular perpendicularly, to the axis A and / or the application channel 7 .

[0286] The predetermined breaking zone 9 is preferably arranged close to an axial end of the channel 7 and / or the application package 1. Preferably, the distance between the predetermined breaking zone 9 and the axial end 7A of the application channel 7 is at most 15 mm or less, preferably at most 10 mm or less. The distance between the predetermined breaking zone 9 and an axial end 1A of the application package 1 is preferably at most 25 mm or less, in particular at most 20 mm or less.

[0287] Preferably, the distance between the predetermined breaking zone 9 and the axial end 7A of the application channel 7 is greater than 15% or 20% and / or less than 40% or 30% of the total length of the application channel 7, particularly preferably about 20%.

[0288] Preferably, the distance between the predetermined breaking zone 9 and the axial end 1A of the application package 1 is greater than 10% or 15% of the total length or longitudinal extension of the application package 1 along the axis A and / or less than 40% or 30% of the total length or longitudinal extension of the application package 1 along the axis A, particularly preferably about 20%.

[0289] The predetermined breaking zone 9 preferably defines a tip 10 of the application package 1 and / or the bottom part 3. In particular, the tip 10 is a part or section of the application package 1 or the bottom part 3 which is opposite the chamber 6 with respect to the predetermined breaking zone 9.

[0290] The tip 10 can preferably be folded or bent, in particular by folding or bending the application package 1 along the predetermined breaking zone 9. In particular, this causes the application package 1 or at least the bottom portion 3 to break, so that the application package 1 can be opened and / or the pharmaceutical product 2 can be removed, dispensed or pushed out through the application channel 7. In particular, in Figure 2 This is shown in .

[0291] Preferably, an open end 7B of the cavity 5, in particular of the application channel 7, is produced by breaking the application package 1, in particular along the predetermined breaking zone 9 and / or by bending / folding the tip 10, such as Figure 2 As shown in .

[0292] By opening the administration package 1 as described, the administration package 1 is preferably transformed into a pipette and / or can preferably be used to administer the pharmaceutical product 2 to a patient. In particular, the pharmaceutical product 2 can be administered by or from the administration package 1 by pressing on the chamber 6, so that the pharmaceutical product 2 is forced through the administration channel 7 and leaves / exits the administration channel 7 at its open end 7B at the predetermined breaking zone 9.

[0293] Preferably, it is necessary to press / push on the chamber 6 to remove the pharmaceutical product 2. In other words, the application channel 7 and / or the open end 7B are preferably configured or dimensioned such that no product 2 can escape due to (only) gravity and / or such that no product 2 flows out when the application package 1 is held, wherein the open end 7B points downwards without exerting further force, in particular without pushing on the chamber 6. In this way, accidental removal of the pharmaceutical product 2 is prevented.

[0294] Particularly preferably, the flow cross section of the chamber 5, in particular the application channel 7, is narrowed or reduced at the open end 7B and / or in the region of the predetermined breaking zone 9. Thus, preferably, a narrowed flow channel or a cross-sectional reduction or nozzle is formed at the open end 7B and / or in the region of the predetermined breaking zone 9. Reference will be made later to Figures 9 to 11 Explain this in more detail.

[0295] exist Figure 2 In the example shown in , the cover 4 preferably remains intact or unbroken. In particular, after folding or bending the application package 1 or opening the application package 1, the tip 10 is preferably still connected to the application package 1 via the cover 4. However, other solutions are also possible here, in which the cover 4 is also completely or at least partially broken and / or in which the tip 10 is completely removed from the application package 1.

[0296] The application package 1 is preferably packaged in a secondary package 11 , in particular after production of the application package 1 , for transport and / or storage and / or before use of the application package 1 for applying the contained pharmaceutical product 2 to a patient. Figure 3 Secondary packaging 11 is shown in FIG.

The lid 13 preferably closes (especially completely closes) the receptacle 14. The lid 13 is preferably fixed (especially glued) to the base part 12. Preferably, the lid 13 can be peeled off from the base part 12 so that the application package 1 can be removed from the secondary package 11 or the receptacle 14.

[0299] Figure 4 In a very schematic illustration, a device 100 for producing an application package 1 is shown. Figure 4 A device 100 and a method for producing an application package 1 are described.

[0300] The methods as described herein are preferably performed with the apparatus 100. Then, the apparatus 100 is preferably configured for performing the methods described herein.

[0301] The apparatus 100 preferably comprises a heating device 101 and a molding tool 102 .

[0302] To produce the application package 1, a plastic sheet 200 is preferably guided through the apparatus 100 and the application package 1 is formed from the plastic sheet 200 by thermoforming, in particular deep drawing. In particular, the thermoforming is carried out in the heating device 101 and / or the molding tool 102.

[0303] Preferably, the plastic sheet 200 is provided rolled up and / or on a roll or in the form of a roll, such as Figure 4 Preferably, in particular in an unfolding or feeding step, the plastic sheet 200 is loosened / unfolded and guided into the apparatus 100 and / or the heating device 101. However, the plastic sheet 200 can also be fed into the apparatus 100 and / or the heating device 101 in any other desired form or manner.

[0304] The plastic sheet 200 may be guided through the apparatus 100 continuously or stepwise, as desired.

[0305] After unwinding / feeding the plastic sheet 200 and / or during a heating step, the plastic sheet 200 is preferably at least partially heated by means of a heating device 101 .

[0306] The heating device 101 is preferably configured for at least partially heating the plastic sheet 200. In particular, the heating device 101 is configured for heating sub-regions of the plastic sheet 200, which then preferably form the bottom portion 3 of the application package 1, in particular in the molding tool 102.

[0307] The heating device 101 is preferably configured to heat the plastic sheet 200 from both sides. Preferably, the heating device 101 comprises at least one heating plate 101A, 101B, in particular two heating plates 101A, 101B, which are hereinafter referred to as an upper heating plate 101A and a lower heating plate 101B. The upper and lower heating plates 101A, 101B are configured to heat different sides of the plastic sheet 200.

[0308] Preferably, the heating device 101, in particular, the heating plate(s) 101A, 101B heats the plastic sheet 200 to a plasticizing temperature or a thermoforming temperature.

[0309] The plasticizing or thermoforming temperature is preferably a temperature at which the plastic sheet 200 is plasticized and / or thermoformable, in particular a temperature at which the plastic sheet 200 softens and / or becomes plastically deformable. A plastic material (here, the plastic sheet 200) can preferably be deformed when it has reached the plasticizing or thermoforming temperature and retain the new form after cooling or dropping below the plasticizing or thermoforming temperature.

[0310] Preferably, the heating device 101 heats the plastic sheet 200 to a temperature of 180°C and / or the plasticizing or thermoforming temperature is at least 150°C and / or at most 200°C.

[0311] The two heating plates 101A, 101B can be operated at the same temperature or at different temperatures. Preferably, if the plastic sheet 200 is multi-layered, in particular with layers of different materials and / or with different plasticizing / thermoforming temperatures, the two heating plates 101A, 101B are operated at different temperatures, in particular corresponding to the respective plasticizing / thermoforming temperatures of the layers of the plastic sheet 200 facing the respective heating plates 101A, 101B.

[0312] After heating and / or in a (thermo)forming step, the (heated) plastic sheet 200 is preferably formed (in particular thermoformed) by means of the moulding tool 102 .

[0313] The molding tool 102 is preferably configured for forming the shape of the bottom portion 3 from the plastic sheet 200. In particular, the molding tool 102 is configured for respectively stretching the plastic sheet 200 or the heated sub-region of the plastic sheet 200. In particular, the heated region of the plastic sheet 200 is stretched in or into the molding tool 102.

[0314] The molding tool 102 comprises at least one mold 102A, 102B. Preferably, the molding tool 102 comprises two molds 102A, 102B, hereinafter referred to as a female mold 102A and a male mold 102B.

[0315] Preferably, the plastic sheet 200 is stretched into the female mold 102A and / or onto the male mold 102B.

[0316] The forming or stretching is preferably performed by forcing the plastic sheet 200 against the molding tool 102 or the mold 102A and / or 102B, preferably by generating an overpressure or blowing a gas (especially air) against the plastic sheet 200, and / or by generating a negative pressure in the molding tool 102 or the mold 102A and / or 102B. In addition or alternatively, the plastic sheet 200 can be forced against the molding tool 102 or the mold 102A and / or 102B by means of a stamp. Particularly preferably, if two molds 102A, 102B are provided, one of the molds 102A, 102B acts as a stamp. In particular, in addition to a gas, a stamp can also be provided only in sub-areas, for example, in areas that require more precise forming, such as the application channel 7.

[0317] The predetermined breaking zone 9 is preferably produced in the molding tool 102 and / or during the molding step, and / or the apparatus 100, in particular the molding tool 102, is configured for this purpose. This will be explained in more detail later.

[0318] Preferably, the predetermined breaking zone 9 is created / produced only in the (thermo)forming step and / or with the aid of the molding tool 102. In particular, the proposed method does not comprise a step in which the plastic sheet 200 is (partially) cut in order to produce a predetermined breaking zone 9, and / or the proposed device 100 does not have or require a cutting tool for this purpose.

[0319] However, the predetermined breaking zone 9 can also be produced / produced only substantially or mainly in a (thermo)forming step and / or with the aid of the molding tool 102. Preferably, this is to be understood as meaning that the main or necessary steps for producing / forming the predetermined breaking zone 9 are performed during (thermo)forming and / or using the molding tool 102.

[0320] In contrast, in the prior art a predetermined breaking zone is only produced after the (thermo)forming step (e.g. by perforating an otherwise finished package along a specific line) or by cutting a plastic sheet before the (thermo)forming step.

[0321] In the prior art, in particular in EP 2 998 098 A1 and EP 2 998 099 A1, the cutting of the plastic sheet is a main or necessary or generating step that is carried out before the thermoforming step. When the plastic sheet is deep-drawn, the cutting of the plastic sheet can further deform the sheet, however, this deformation does not produce a predetermined breaking zone, because the production occurs previously by cutting the sheet. Moreover, this deformation is of course not a necessary or main step to produce the predetermined breaking zone. This is evident from the fact that in the prior art, without cutting, the predetermined breaking zone would not be formed at all.

[0322] Therefore, the predetermined breaking zone 9 of the present invention is preferably produced before or after the step of forming the bottom portion and / or without cutting and / or without a cutting step without using a cutting tool.

[0323] In the sense of the present invention, a perforation, scoring or similar operation is preferably also understood as "cut or (cuts)". Therefore, the term "no cutting" preferably also includes expressions such as "no perforation" or similar or can be replaced or supplemented by expressions such as "no perforation" or similar. Similarly, a cutting step / tool ​​can also be a perforation step / tool, etc.

[0324] The molding tool 102 is preferably configured to form a plurality of bottom portions 3 simultaneously (simultaneously / at the same time) or in one step. Figure 4 In the illustrated example shown in , twelve bottom portions 3 are formed simultaneously. However, other solutions, for example, in which only one bottom portion 3 is formed in one forming step, are also possible.

[0325] Preferably, the molding tool 102 and / or the mold(s) 102A, 102B are exchangeable in order to produce differently shaped administration packages 1 (in particular the bottom part 3 ), for example to accommodate different volumes of the chamber 6 or of the pharmaceutical product 2 .

[0326] After forming and / or in a filling step, the bottom portion(s) 3 (in particular one or more cavities 5) formed in the plastic sheet 200 is filled with the pharmaceutical product 2, in particular by means of a filling device 103, which is arranged at Figure 4 It is schematically indicated by a dotted line.

[0327] Filling is preferably performed after the plastic sheet 200 or the heated / thermoformed region thereof has hardened and / or cooled or dropped below the plasticizing / thermoforming temperature.

[0328] After filling and / or in a covering / closing step, a cover sheet 300 is applied, in particular fixed or joined, to the plastic sheet 200. Closing / covering is preferably performed in a covering device 104, in particular a sealing device.

[0329] Preferably, the bottom portion(s) 3 or one or more cavities 5 formed in the plastic sheet 200 are covered or closed by means of the cover sheet 300, thereby forming respective cover(s) 4.

[0330] Preferably, the cover sheet 300 is provided rolled up and / or provided on a roll or in the form of a roll, such as Figure 4 Preferably, the cover sheet 300 is unwound / unrolled and introduced into the apparatus 100 and / or the covering device 104 (in particular together with the plastic sheet 200). However, the (wound) cover sheet 300 can also be completely positioned in the covering device 104.

[0331] The covering device 104 is preferably configured to join or seal, in particular heat seal, the cover sheet 300 to the plastic sheet 200 or the bottom portion(s) 3 in a fluid-tight, in particular liquid-tight and / or air-tight manner.

[0332] Preferably, the cover sheet 300 of the cover 3 is joined or sealed to the plastic sheet 200 of the bottom portion 3 by sealing, preferably heat sealing, the sealing layers 205 and 305 of the cover sheet 300 and the plastic sheet 200. Figures 5 to 8 The sealing layers 205 and 305 are explained in detail with reference to the explanation of FIG.

[0333] To fix the cover sheet 300 to the plastic sheet 200, the covering device 104 is preferably brought into contact with the cover sheet 300 so that the cover sheet 300 is pressed against the plastic sheet 200 at least in the region of the bottom portion(s) 3 or its / their edge(s) 3A. The covering device 104 is preferably heated at least in the contact region so that the cover sheet 300 is heat-sealed to the plastic sheet 300 at least in this region.

[0334] The joining / sealing is preferably carried out at least in the region of the edge(s) 3A of the bottom part(s) 3, or the covering device 104 is configured for this purpose. For this purpose, the covering device 104 preferably comprises (for each bottom part 3) an annular sealing tool (not shown) which at least substantially has the form of the edge 3A and / or can be heated.

[0335] Particularly preferably, the joining / sealing is performed in addition to the region of the edge(s) 3A also in the region surrounding the edge(s) 3A and / or in the region which will later form the rim(s) 8 .

[0336] In principle, the cover device 104 may not contact this additional area, but only use its radiant heat when heat sealing the cover sheet 300 to the plastic sheet 200. This would result in a reduced bond strength compared to the area where the cover device 102 contacts the cover sheet 300. However, solutions are also possible where a contact is also established in this area and / or with a constant bond strength.

[0337] After covering / closing and / or in a separation step, the application package(s) 1 formed by the plastic sheet 200 and the cover sheet 300 are separated from these sheets and / or from each other.

[0338] For this purpose, the apparatus 100 can comprise a separating device (not shown), preferably downstream of the covering device 104. However, a separating device can also be integrated into the covering device 104 and / or the covering device 104 can also be configured for separating the application package(s) 1 .

[0339] Preferably, the application package(s) 1 are trimmed, punched or cut.

[0340] The separation (in particular the punching / cutting) is preferably carried out along a line which has a (constant) distance to the edge(s) 3A and / or such that the edge(s) 8 are formed. The line along which the application package 1 is separated (in particular cut or punched) is formed by Figure 4 The dotted line in the figure indicates schematically.

[0341] The application package 1 preferably consists of a base part 3 comprising a special functional layer, in particular a special layer structure, and a cover 4 . Figures 5 to 8 2 shows a plastic sheet 200 of the bottom portion 3 and a cover sheet 300 of the cover 4, or a preferred embodiment for producing the plastic sheet 200 and the cover sheet 300 of the bottom portion 3 and the cover 4.

[0342] As described above, the plastic sheet 200 of the bottom portion 3 is a multi-layer film. The plastic sheet 200 of the bottom portion 3 includes at least five layers:

[0343] an outer thermoformable layer 201,

[0344] a cyclic olefin copolymer (COC) layer 202,

[0345] an inner thermoformable layer 203,

[0346] A barrier layer 204 and

[0347] A sealing layer 205 is provided.

[0348] The cyclic olefin copolymer layer 202 is disposed between the outer thermoformable layer 201 and the inner thermoformable layer 203 and the barrier layer 204 is disposed between the sealant layer 205 and the inner thermoformable layer 203 .

[0349] Preferably, the plastic sheet 200 includes the above-mentioned at least five layers in the layer sequence as described above, that is, the plastic sheet 200 of the bottom portion 3 includes at least five layers in the following layer sequence:

[0350] The outer thermoformable layer 201 is followed by

[0352] The inner thermoformable layer 203, followed by

[0353] The barrier layer 204 is followed by

[0354] Sealing layer 205.

[0355] Particularly preferably, it is envisaged that the abovementioned layers follow one another, ie according to the above preferred embodiments of the invention the abovementioned layers are formed continuously or sequentially and / or are not separated from one another by intermediate layers.

[0356] The outer thermoformable layer 201 usually forms one outer surface of the application package 1 according to the invention.

[0357] Preferably, the plastic sheet 200 of the bottom portion 3 further comprises Figure 5 204. The intermediate layer 206 is shown in FIG. The intermediate layer 206 can be omitted in the plastic sheet 200, but further enhances the compatibility of the plastic sheet 200, especially the inner thermoformable layer 203 and the barrier layer 204. The intermediate layer 206 is usually arranged between the inner thermoformable layer 203 and the barrier layer 204. The intermediate layer 206 usually includes the same material as the sealing layer 205 or is composed of the same material as the sealing layer 205, and usually also has the same thickness. The sealing layer 205 is preferably a heat sealing layer for joining / sealing the bottom portion 3 and the cover 4.

[0366] The cyclic olefin copolymer layer 202 is a main layer of the plastic sheet 200. It includes or consists of a cyclic olefin copolymer (COC), preferably consists of a cyclic olefin copolymer (COC).

[0367] The cyclic olefin copolymer layer 202 generally provides stiffness and structural integrity to the bottom portion 3 of the application package 1, in particular after deep drawing. Furthermore, the cyclic olefin copolymer layer 202 is brittle and breaks under increased pressure, which makes it suitable for producing a disposable application package with a breaking zone 9 for opening the application package 1. The cyclic olefin copolymer layer 202 preferably has a thickness in the range from 200 μm to 600 μm, in particular 250 μm to 500 μm, preferably 300 μm to 450 μm, more preferably 350 μm to 400 μm, particularly preferably 360 μm to 390 μm.

[0368] The inner thermoformable layer 203 and the outer thermoformable layer 201 enhance the thermoformable properties of the plastic sheet 200 and provide more flexibility to the plastic sheet 200 , thereby enhancing the machinability of the plastic film 200 and providing protection to the brittle COC layer 202 .

[0369] The outer thermoformable layer 201 and the inner thermoformable layer 203 preferably have a thickness in the range from 10 μm to 40 μm, in particular 12 μm to 35 μm, preferably 15 μm to 30 μm, more preferably 18 μm to 27 μm, particularly preferably 22 μm to 25 μm.

[0374] According to the invention, it is preferred if the polymer of the barrier layer 204 is selected from the group consisting of ethylene vinyl alcohol (EVOH), polyvinylidene chloride (PVDC), polychlorotrifluoroethylene (PCTFE) and mixtures thereof. Best results are obtained if the polymer of the barrier layer 204 is ethylene vinyl alcohol (EVOH). The barrier layer 204 prevents substances from the environment from penetrating the package 1 and deteriorating the pharmaceutical product 2 on the one hand, and prevents any undesirable interaction between the pharmaceutical product 2 and the package 1 on the other hand. The barrier layer (especially comprising EVOH or consisting of EVOH) exhibits excellent barrier properties to chemicals and oxygen.

[0375] The barrier layer 204 has a thickness in the range from 2 μm to 20 μm, particularly 5 μm to 15 μm, preferably 7 μm to 12 μm.

[0378] It is preferred if the polymer of the sealing layer 205 and / or the intermediate layer 206 is selected from the group consisting of polypropylene (PP), polyethylene (PE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), metallocene linear low-density polyethylene (mLLDPE), very low-density polyethylene (VLDPE) or a mixture thereof. The best results are obtained if the polymer of the sealing layer 205 and / or the intermediate layer 206 is polyethylene (PE).

[0379] The sealing layer 205 and / or the intermediate layer 206 have a thickness in the range of from 10 μm to 50 μm, in particular 15 μm to 40 μm, preferably 17 μm to 35 μm, more preferably 20 μm to 30 μm, particularly preferably 22 μm to 27 μm. As described above, preferably, the sealing layer 205 and the intermediate layer 206 include or consist of the same polymer and have the same thickness.

[0380] Therefore, a very preferred plastic sheet 200 according to the invention comprises or consists of the following layer structure with the following layer sequence:

In other words, apart from the predetermined breaking zone 9, the different embodiments of the application package 1 are preferably identical.

[0460] Preferably, unless explicitly stated otherwise, aspects, features, and explanations described for one embodiment are also applicable to other embodiments even if not repeated.

[0461] In addition, regarding the application package 1 (especially reference Figures 1 to 3 ), method and apparatus for producing the same 100 (particularly with reference to Figure 4 ) and preferably multilayer structures (especially reference Figures 5 to 8 )'s previously described aspects, features and explanations are preferably additionally or correspondingly applicable to the embodiments described below (even if there is no repetition).

[0462] The embodiments of the administration package 1 described below preferably have the general reference Figures 1 to 3 The aspects and features of the described application package 1.

[0468] As indicated by the shadows, Fig.11 The rim 8 shown in the figure is located behind the cross-sectional plane. The cover 4 preferably extends along the upper surface of the rim 8 and over the cavity 5 or application channel 7, thereby closing the cavity 5 or application 7 from above (in the orientation shown in the figure).

[0469] In a first embodiment, the predetermined breaking zone 9 extends only above the chamber 5, in particular the application channel 7 of the chamber 5, in particular as Fig. 9Preferably, in the first embodiment, no predetermined breaking zone 9 is provided at the edge 8 and / or the edge 8 does not comprise a predetermined breaking zone 9. This preferably enhances the stability of the application package 1 and / or reduces the risk of accidental opening of the application package 1.

[0470] In this sense, the term "predetermined breaking zone" preferably means a region of the application package 1, in particular the bottom part 3, which is specially prepared or manufactured to ensure the breaking / opening of the application package 1. Therefore, in particular, the predetermined breaking zone 9 is preferably a material weakening and throughout the present application, the term "predetermined breaking zone" can be replaced by "material weakening".

[0471] Preferably, also when the predetermined breaking zone 9 is provided only in the region of the cavity 5 or the application channel 7, the rim 8 nevertheless also breaks when the application package 1 is opened, in particular when the tip 10 is bent / folded, preferably in a defined manner, along the predetermined breaking zone 9. In other words, when bending / folding the tip 10, the material preferably breaks at the predetermined breaking zone 9 and the break propagates, in particular in a defined manner, into the rim 8, causing the entire tip 10 of the base portion 3 to break.

[0476] The groove 15 preferably has an angle W and a depth D and / or is defined by an angle W and a depth D.

[0477] The angle W is preferably a smaller angle between the main extension plane of the outer surface 16 and the main extension plane of the inclined or inclined surface of the groove 15, especially at the edge of the predetermined breaking zone 9 or the groove 15 (i.e., the edge where the outer surface 16 bends inward and / or begins to form a groove / recess).

[0478] If the recess 15 or its cross section is at least substantially triangular or wedge-shaped, the angle W is preferably the angle between one of the legs and the base of the (isosceles) triangular cross section.

[0479] However, the groove 15 may also be characterized by any other suitable angle (which can be calculated as 180° minus W) which can preferably be determined from the angle W (for example, the angle at which the outer surface 16 actually bends inwardly or toward the cavity 5 or the application channel 7) or, in particular, in the case of a triangle or a wedge, by the opening angle of the groove 15 (i.e., the angle contained between the two inclined surfaces of the groove 15) which can be calculated as 180° minus 2 times W.

[0480] The depth D is preferably the distance from a main extension plane of the outer surface 16 to the lowermost area of ​​the recess 15 , in particular measured perpendicularly to the main plane.

[0487] Preferably, a projection 17 is formed on an inner surface 18 of the application package 1 , in particular the bottom portion 3 , in the predetermined breaking zone 9 .

Particularly preferably, the inner surface 18 is formed by the sealing layer 205.

[0489] Thus, the outer surface 16 and the inner surface 18 are preferably two opposite surfaces forming the wall of the bottom portion 3. Particularly preferably, the inner surface 18 is the surface in contact with the pharmaceutical product 2 at least when the pharmaceutical product 2 is dispensed and / or the surface of the sealing layer 205. Particularly preferably, the outer surface 16 is the surface in contact with the environment and / or the surface of the outer thermoformable layer 201.

[0490] The protrusion 17 is preferably arranged opposite to the groove 15 .

[0491] Preferably, the protrusion 17 is formed to correspond to the groove 15 , in particular, extends in the same direction as the groove 15 , has the same length and / or width as the groove 15 , and / or has the same shape and / or angle as the groove 15 .

[0492] Preferably, the predetermined breaking zone 9 is a region having the same thickness T as a region of the bottom portion 3 surrounding the predetermined breaking zone 9. In other words, the thickness T of (the wall of) the bottom portion 3 is preferably at least substantially constant in the region including and surrounding the predetermined breaking zone 9.

[0493] Therefore, preferably, the thickness T of (the wall of) the bottom portion 3 in the region of the groove 15 and / or the projection 17 is at least substantially the same as in the region surrounding / adjacent to the groove 15 and / or the projection 17 .

[0494] The thickness T is preferably the distance between the outer surface 16 and the inner surface 18. In the predetermined breaking zone 9, the thickness T is preferably the distance between (the surface of) the groove 15 and the protrusion 17.

[0495] The at least substantially constant thickness T is preferably achieved by forming the projection 17 accordingly, in particular by having the projection 17 have the same or at least nearly the same height as the depth D of the recess 15. In other words, the projection 17 is preferably at least substantially as high as the depth of the recess 15, and / or the outer surface 16 is at least substantially as much concave as the inner surface 18 is convex (at the predetermined breaking zone 9).

[0496] The thickness T of the bottom portion 3, preferably both in the predetermined breaking zone 9 and in the area surrounding it, is preferably at least 230 μm, in particular at least 300 μm or 400 μm, more preferably 450 μm or 480 μm, and / or at most 750 μm, in particular 650 μm or 600 μm, more preferably 500 μm or 520 μm.

[0497] In the first embodiment, the predetermined breaking zone 9 is preferably formed as a bend or a kink or a fold in (the wall of) the bottom portion 3 .

[0498] In a cross section (in particular perpendicular to its longitudinal extension), the predetermined breaking zone 9 or (the wall of) the bottom part 3 in the region of the predetermined breaking zone 9 is preferably at least substantially V-shaped.

[0499] Preferably, a narrowed flow channel or a cross-sectional reduction or a nozzle 19 is formed at / in or by means of the predetermined breaking zone 9 , in particular in the chamber 5 or the application channel 7 .

[0500] The channel height and / or the flow cross section of the application channel 7 is preferably defined or delimited by the inner surface 18 and the cover 4 , in particular the surface of the cover 4 facing the application channel 7 or formed by the layer 305 .

[0501] The height and / or width of the application channel 7 remote from the predetermined breaking zone 9 or the cross-sectional reduction or the nozzle 19 is preferably greater than 0.5 mm, in particular greater than 1 mm and / or less than 4 mm or 3 mm.

[0502] The height and / or width of the application channel 7 is preferably reduced by at least 0.05 mm or more and / or at most 0.5 mm or less, particularly preferably by 0.1 mm, 0.2 mm, 0.3 mm or 0.4 mm at / in or by the predetermined breaking zone 9 .

[0503] Preferably, the application channel 7 is narrowed or its (flow) cross section is reduced or the nozzle 19 is formed by means of a projection 17. In particular, the projection 17 projects into the application channel 7 and / or towards the cover 4, thereby narrowing the channel and / or reducing the (flow) cross section.

[0504] When the application package 1 is opened (particularly by folding / bending along the predetermined breaking zone 9 or groove 15), a narrowed flow channel or a cross-sectional reduction or nozzle 19 is preferably formed or positioned at the open end 7B, in particular where the drug product 2 exits the application package 1.

[0505] As already explained above, the application channel 7 and / or the open end 7B are preferably configured or dimensioned such that no product 2 can escape due to (only) gravity. This is particularly preferably achieved at least partially by means of a narrowing flow channel or cross-sectional reduction or nozzle 19.

[0506] Preferably, the application channel 7 or the open end 7B is narrowed, in particular by means of the protrusion 17, so that even if the open end 7B points downward, the drug product 2 is not discharged / leaves through the application channel 7 or the open end 7B without applying an additional force (for example, by pressing on the chamber 6).

[0507] The pharmaceutical product 2 is therefore preferably dispensed from the opened administration package 1 simply by pressing on the chamber 6 .

[0508] Preferably, when dispensing the pharmaceutical product 2 and / or pressing against the chamber 6 , the pharmaceutical product 2 is accelerated when leaving the application package 1 , in particular at the open end 7B, particularly preferably by means of a narrowing flow channel or cross-sectional reduction or nozzle 19 .

[0509] Preferably, the narrowed flow channel or the cross-sectional reduction or the nozzle 19 (also) prevents the drug product 2 from flowing, in particular from the chamber 6, through the narrowed flow channel or the cross-sectional reduction or the nozzle 19 and / or into the tip 10 or the portion of the application channel 7 comprised by the tip 10 and / or towards the axial end 7A, in particular before opening the application package 1. Thus, preferably, the drug product 2 is prevented from accumulating at the axial end 7A or in the tip 10. In this way, preferably, no drug product 2 is wasted or spilled when opening the application package 1 or disposing of the tip 10.

[0510] Fig.12 Corresponding to Fig.11 An enlarged detail of the first embodiment shown in FIG. 1 illustrates an enlarged detail of a second embodiment of the application package 1 shown in the region of the breaking zone 9 .

[0511] Preferably, the only difference between the first and the second embodiment is that the application package 1 or the bottom part 3 or the predetermined breaking zone 9 comprises no projection 17 and / or no narrowing flow channel or cross-section reduction or nozzle 19 .

[0512] The application channel 7 of the second embodiment preferably has a constant distance between the inner surface 18 and the cover 4 and / or a constant (flow) cross section, in particular also in the predetermined breaking zone 9 .

[0513] Along axis A and / or along Fig.12 In the cross section shown in , the inner surface 18 is preferably at least substantially flat, in particular (also) in the predetermined breaking zone 9.

[0514] Preferably, in the predetermined breaking zone 9, the thickness T of (the wall of) the bottom portion 3 is reduced or decreased compared to the area surrounding the predetermined breaking zone 9. Particularly preferably, the thickness T is reduced by the depth D of the groove 15.

[0515] The ratio of the thickness at (the narrowest area of) the predetermined breaking zone 9 to the thickness in the area surrounding the predetermined breaking zone 9 is preferably at least 0.1 or 0.2 and / or at most 0.9 or 0.8.

[0516] Embodiments are also possible in which the application package 1 (in particular the bottom part 3 or the predetermined breaking zone 9) has a projection 17 or a narrowed flow channel or a cross-sectional reduction or a nozzle 19, but nevertheless has a non-constant thickness T compared to the area surrounding the projection 17 or the predetermined breaking zone 9, for example a reduced thickness T in the area of ​​the projection 17 or the predetermined breaking zone 9.

[0517] It is also conceivable that the thickness T decreases in some areas and increases in another area compared to the average thickness T. For example, the thickness T may decrease at the tip of the protrusion 17 and increase at the foot / base of the protrusion 17 .

[0518] Preferably, the predetermined breaking zone 9 or a material weakening of the bottom portion 3 is formed by a bend / kink, by a material reduction / thickness reduction or by a combination thereof.

[0519] In the following, a third and a fourth embodiment of the application package 1 are described which preferably differ from the first and the second embodiment in that the predetermined breaking zone 9 or its groove 15 extends over the rim 8 or is formed at both the application channel 7 and the rim 8 .

Fig.14 and Fig.15 The section shown in FIG. 1 is along the axis A, ie along the application channel 7 or in the region of the application channel 7 .

[0521] Fig.16 Similar to Fig.15 An enlarged view shows a schematic cross section of the application package 1 according to the third embodiment in the region 1 of the rim 8. Since in these embodiments the rim 8 does not comprise a predetermined breaking zone 9 or a groove 15, similar figures for the first and second embodiments have been omitted.

[0522] Fig.17 Corresponding to Fig.11 , Fig.12 and Fig.15 One of the enlarged details of further embodiments shown in FIG. 1 shows an enlarged detail of a fourth embodiment of the application package 1 in the region of the breaking zone 9 . Fig.18 Corresponding to Fig.16 One illustration shows an enlarged detail of a fourth embodiment of the application package 1 in the region of the breaking zone 9 at the edge 8 .

[0523] In both the third and fourth embodiments, the predetermined breaking zone 9 or the groove 15 preferably extends over the cavity 5, in particular the application channel 7 and the rim 8. In other words, the predetermined breaking zone 9 or the groove 15 preferably extends over the entire width of the application package 1, i.e. over the entire extension of the application package 1 in a direction transversely or perpendicular to (the longitudinal extension of) the application channel 7 or the axis A.

[0524] Preferably, the area of ​​the predetermined breaking zone 9 at the edge 8 has the same or similar characteristics as the area of ​​the predetermined breaking zone 9 at the cavity 5 or the application channel 7 .

[0525] The above explanations regarding the predetermined breaking zone 9 , the groove 15 , the angle W, the depth D etc. preferably also apply to the predetermined breaking zone 9 of the third and fourth embodiments (particularly preferably in the region of both the cavity 5 and the rim 8 ).

[0526] Preferably, the groove 15 has the same or similar properties in the region of the rim 8 as in the region of the cavity 5 or of the application channel 7 , for example the same angle W, the same depth D or similar.

[0527] However, solutions are also possible in which the predetermined breaking zone 9 and / or the recess 15 are different at the edge 8. For example, the recess 15 can have a smaller depth D at the edge 8 than at the cavity 5 or application channel 7.

[0528] Preferably, according to Figures 13 to 16 The third implementation method and the Fig.17 and Fig.18 The main or only difference between the fourth embodiment and the present invention is whether the protrusion 17 is formed on the edge 8.

[0529] Preferably, the edge 8 in the third embodiment does not include a protrusion 17, such as Fig.16 As can be seen in the figure, and / or the edge 8 in the fourth embodiment includes a protrusion 17, such as in particular Fig.18 Visible in.

[0530] In the fourth embodiment, the projection 17 preferably extends over the entire width of the application package 1, i.e. over the entire extension of the application package 1 in a direction perpendicular to (the longitudinal extension of) the application channel 7 or the axis A. Thus, in particular, the edge 3A and / or the rim 8 also comprises the projection 17.

[0531] Preferably, the projection 17 has the same or similar properties in the region of the rim 8 as in the region of the cavity 5 or the application channel 7. However, solutions in which the projection 17 is different at the rim 8 are also possible.

[0532] Preferably, the cover 4 follows or adapts to the surface of the rim 8. In other words, in the fourth embodiment, in the region of the predetermined breaking zone 9 or projection 17, the cover 4 (also) has a protrusion or projection on its outer side and a groove on its inner side, such as Fig.17 and Fig.18 In the third embodiment and / or when the edge 8 is flat or does not include a projection 17, the cover 4 is preferably at least substantially flat, in particular also in the region of the predetermined breaking zone 9, such as in Fig.15 and Fig.16 Visible in.

[0533] In the third embodiment, the thickness T is preferably reduced in the region of the predetermined breaking zone 9 at the edge 8 compared to the surrounding region and / or the region of the predetermined breaking zone 9 at the application channel 7 .

[0534] In the fourth embodiment, the thickness T is preferably at least substantially constant over the entire length of the predetermined breaking zone 9 .

[0535] Preferably, the application package 1 according to the third embodiment comprises a narrowed flow channel or a cross-sectional reduction or a nozzle 19 .

[0536] Preferably, the application package 1 according to the fourth embodiment has an at least substantially constant flow cross section and / or does not comprise a narrowing flow channel or a cross-section reduction or a nozzle 19. This is achieved in particular by shaping the cover 4 accordingly, in particular with a non-planar surface in the region of the predetermined breaking zone 9 or the projection 17. However, solutions are also possible in which the cover 4 is non-planar only at the edge 8, but is still planar where it covers the cavity 5 or the application channel 7, in particular in the region framed by the edge 3A.

[0537] Any combination of different embodiments is possible. For example, the predetermined breaking zone 9 of the third embodiment can also be formed without a protrusion 17 as in the second embodiment.

Specifically, the plastic sheet 200 lies flat against the female mold 102A or surface 102D and / or the male mold 102B or surface 102E.

[0565] Particularly preferably, the plastic sheet 200 (also) adapts or lies flat on the forming device 102C, the protrusion 102F and / or the recess 102G (especially when forced against the forming device 102C, the protrusion 102F and / or the recess 102G), thereby forming a predetermined breaking zone 9, a groove 15 and / or a protrusion 17.

[0566] Depending on the desired form of the predetermined breaking zone 9, the forming device 102C is shaped accordingly.

[0567] The shaping device 102C can be provided only in the region of the molding tool 102, in particular one or both molds 102A, 102B, in which the application channel 7 is formed or is to be formed. Alternatively, the shaping device 102C can also be provided in the region in which the rim 8 is formed.

[0568] When forming the bottom portion 3, in particular in the shaping step, the predetermined breaking zone 9 is or will be formed only where the shaping means 102C are provided.

[0569] When the forming device 102C is provided only in the region where the application channel 7 is formed or is to be formed, the predetermined breaking zone 9 is or will be formed only in the region of the application channel 7 accordingly. Figures 9 to 11 The first embodiment shown in and / or according to Fig.12 One of the application packages 1 or the bottom part 3 of the second embodiment shown in and / or any other embodiment in which the predetermined breaking zone 9 is provided only at the application channel 7 can be formed / produced in this way.

[0570] When the forming device 102C is also provided in the region where the edge 8 is formed or to be formed, the predetermined breaking zone 9 is or will be formed accordingly in the region of the edge 8. Figures 13 to 16 The third embodiment shown in and / or according to Fig.17 and Fig.18 The fourth embodiment shown in FIG. 1 and / or any other embodiment in which the predetermined breaking zone 9 is also provided at the edge 8 (e.g. also at Figures 1 to 3One of the application packages 1 or the bottom part 3 (the embodiment shown in FIG. 4 ) can be formed / produced in this way.

[0571] Preferably, when two molds 102A, 102B are provided or in the area where two molds 102A, 102B are provided, the molds 102A, 102B or their surfaces 102D, 102E at least substantially correspond to each other. In particular, the surfaces 102D, 102E are at least substantially identical or have at least substantially the same shape, except for having opposite curvatures. However, in particular areas where the predetermined breaking zone 9 is formed or is to be formed, the molds 102A, 102B or their surfaces 102D, 102E may be shaped differently.

[0572] Preferably, Fig.19 and Fig. 20 In the embodiment shown in , only the female mold 102A comprises the shaping means 102C. In particular, when a projection or convexity 102F is provided on the female mold 102A or the surface 102D, in particular in the area where the application channel 7 or the predetermined breaking zone 9 is formed or to be formed, no corresponding groove or notch is provided on the male mold 102B.

[0573] like Fig. 20 As can best be seen in FIG. 1 , this preferably results in a predetermined breaking zone 9 without a protrusion 17 and / or with a reduced thickness T. In particular, in this way, a predetermined breaking zone 9 can be formed according to Fig.12 An application package 1 without a protrusion 17 of the second embodiment shown in and / or any other embodiment.

In this way, depending on whether the forming device 102C is provided only in the area of ​​the application channel 7 to be formed or also in the area of ​​the edge 8 to be formed, it is preferably possible to form / produce an application package 1 with a recess 15 and a corresponding projection 17, for example according to Figures 9 to 11 The first embodiment shown in Figures 13 to 18 The administration package 1 of the third or fourth embodiment shown in FIG.

[0575] It is also possible that the parts of the molding device 102C on different molds 102A, 102B correspond to each other only in certain areas, but are different in other areas.

[0576] For example, the forming device 102C or the surface 102D may include a protrusion or projection 102F extending along both the area where the application channel 7 is formed or to be formed and the area where the edge 8 is formed or to be formed, while the forming device 102C or the surface 102E includes a groove or recess 102G only in the area where the application channel 7 is formed or to be formed, but does not include a groove or recess 102G in the area where the edge 8 is formed or to be formed. In this way, preferably, it is possible to form / produce according to Figures 13 to 16 An application package 1 of the third embodiment is shown in FIG.

[0577] The shaping device 102C may be formed integrally with the molding tool 102, in particular the female mold 102A and / or the male mold 102B or their respective surfaces 102D, 102E.

[0581] Particularly preferably, the shaping device 102C is displaceable, adjustable and / or replaceable, in particular within the molding tool 102 or the respective mold 102A, 102B and / or without replacing the entire molding tool 102 or the respective mold 102A, 102B. In particular, the apparatus 100 can preferably be adapted to produce differently shaped predetermined breaking zones 9 without replacing the entire molding tool 102 or the respective mold 102A, 102B.

[0582] Preferably, the molding device 102C forms a displaceable, adjustable and / or replaceable component of the molding tool 102 .

[0585] To produce a different type of application package 1 or predetermined breaking zone 9, or to adapt the device 100 or the molding tool 102 thereto, the molding device 102C or the insert can preferably be exchanged for a different molding device 102C or the insert. Preferably, in this way, an adaptation is possible without replacing the (entire) molding tool 102 or the mold 102A, 102B.

[0586] Alternatively or in addition, the shaping device 102C may be adjustable or displaceable. Preferably, the shaping device 102C is adjustable or displaceable orthogonally and / or parallel to the surfaces 102D, 102E.

[0587] In particular, the height / depth D and / or angle W of the molding device 102C (particularly the protrusion 102F and / or the recess 102G) and the resulting predetermined fracture zone 9 may be adjustable. For example, the degree to which the molding device 102C is inserted or screwed into the molding tool 102 or the mold 102A, 102B may be adjustable.

[0588] Preferably, the shaping device 102C is adjustable or displaceable to determine / change the position of the predetermined breaking zone 9 within the application channel 7, for example, to move it further to the axial end 7A or further away from the axial end 7A.

[0589] Fig. 20 An enlarged detail is shown for producing a material having a reduced thickness T and / or according to Fig.12 The second embodiment shown in the figure and / or having a female mold 102A and a male mold 102B having non-corresponding surfaces 102D, 102E, in particular an example of a predetermined breaking zone 9 of a molding device 102C provided / formed only in the female mold 102A or on the surface 102D.

[0591] Due to the squeezing / compression and / or differently shaped surfaces 102D, 102E and / or the forming device 102C, the thickness T of the plastic sheet 200 is preferably reduced in the region of the forming device 102C. In this way, preferably, a predetermined breaking zone 9 is produced.

[0592] The forming device 102C or the protrusion 102F preferably penetrates the plastic sheet 200 .

[0593] Preferably, only the (mostly) outer layers of the plastic sheet 200, in particular the outer thermoformable layer 201, preferably also the cyclic olefin copolymer layer 202, and optionally also the inner thermoformable layer 203 are affected, penetrated and / or squeezed / compressed by the forming device 102C or during thermoforming.

[0594] Preferably, the innermost layers (in particular at least the barrier layer 204 and the sealing layer 205) remain intact or at least substantially not affected, penetrated or squeezed / compressed by the forming device 102C or during the forming step. Thus, preferably, the sealing and barrier quality of the plastic sheet 200 or the bottom portion 3 is not impaired by or at the predetermined breaking zone 9.

[0595] The height of the forming device 102C or the protrusion 102F is preferably less than the thickness of the plastic sheet 200, and is particularly preferably less than the thickness of the cyclic olefin copolymer layer 202 or less than the sum of the outer thermoformable layer 201 and the cyclic olefin copolymer layer 202, and optionally the inner thermoformable layer 203.

[0596] Particularly preferably, the height of the shaping means 102C or of the projection 102F corresponds to the (desired) depth D of the recess 15 to be produced.

In this case, preferably, the molding device 102C comprises a protrusion or convex portion 102F on one mold and a corresponding groove or notch 102G on the other mold.

[0599] Then, the plastic sheet 200 (in particular all its layers) is pushed inwards or bent or kinked during (thermo)forming, in particular from the protrusion 102F of the mold 102A into the recess 102G of the mold 102B, or vice versa, for example, as Fig. 22 In this way, preferably, a predetermined breaking zone 9 with a groove 15 and a corresponding protrusion 17 is formed.

[0600] In this embodiment, the plastic sheet 200 is preferably at least substantially not squeezed / compressed, in particular at least substantially also none of the outer layers are squeezed / compressed.

[0601] Preferably, all layers of the plastic sheet 200 are affected, since all layers bend / kink inwardly. However, the integrity of the inner layers, in particular at least the barrier layer 204 and the sealing layer 205, is preferably maintained. Therefore, also in this case, the sealing and barrier quality of the plastic sheet 200 or the bottom part 3 is preferably not impaired by or at the predetermined breaking area 9.

[0602] The corresponding surfaces 102D, 102E may be present only in certain areas and / or the plastic sheet 200 may be bent / kinked inwardly only in certain areas or squeezed / compressed in other areas. For example, the plastic sheet 200 may be bent / kinked in an area where the application channel 7 is formed or to be formed and squeezed / compressed in an area where the edge 8 is formed or to be formed, so that a plastic sheet 200 according to the invention can be formed.

In particular, the groove 15 is formed on the inner surface 18, i.e. the surface 18 is recessed in the region of the predetermined breaking zone 9, thereby widening the channel and / or enlarging the (flow) cross section.

[0610] When the application package 1 is opened (particularly by folding / bending along the predetermined breaking zone 9 or groove 15), a widened flow channel or cross-sectional enlargement or diffuser 20 is preferably formed or positioned at the open end 7B, particularly where the drug product 2 exits the application package 1.

[0611] The widening of the passageway at the open end 7B allows easier discharge of the drug product 2. This may be advantageous, for example, for a more viscous fluid.

[0612] The preferred shapes, sizes and / or other features of the predetermined breaking zone 9 (especially the groove 15 and / or the protrusion 17 ) described above for other embodiments are preferably also correspondingly applicable to the fifth embodiment.

[0613] Obviously, in some of the explanations and definitions of the previous embodiments, the term "external surface 16" needs to be replaced by "inner surface 18", and vice versa, to apply to the fifth embodiment. For example, in the fifth embodiment, the depth D is preferably the distance from the main extension plane of the inner surface 18 to the lowest area of ​​the groove 15, in particular the distance measured perpendicular to the main plane, and / or the angle W is preferably the smaller angle between the main extension plane of the inner surface 18 and the main extension plane of the inclined or slanted surface of the groove 15, in particular at the edge of the predetermined breaking zone 9 or groove 15 (i.e. the edge where the inner surface 18 bends outwards and / or begins to form a groove / recess).

[0614] Particularly preferably, the explanations and preferred values ​​for the recess 15 and / or the projection 17 (in particular with regard to the thickness T, the depth D and / or the angle W) preferably also apply accordingly or correspondingly to the fifth embodiment. Fig.25 An angle W of about 40° (an opening angle of about 100°) is exemplarily shown.

[0615] In the fifth embodiment, similarly to the first embodiment, the predetermined breaking zone 9 (in particular the groove 15 and / or the projection 17 ) preferably extends only over the cavity 5 (in particular the application channel 7 ).

[0616] Particularly preferably, the predetermined breaking zone 9 extends, in particular transversely or perpendicularly to the axis A / channel 7 , over the entire cavity 5 or application channel 7 or its width.

[0617] However, the predetermined breaking zone 9 may also extend only partially over the cavity 5 or application channel 7 or its width. For example, the area near the edge 3A and / or where the cavity 5 or application channel 7 transitions into the rim 8 may be (already) free of a predetermined breaking zone 9.

[0618] The above explanations and features concerning the entire or partial extension of the predetermined breaking zone 9 preferably also apply to the previous embodiments (eg the first embodiment) in which the predetermined breaking zone 9 does not extend over the edge 8 .

[0619] Although according to Figure 23 to Figure 25 The illustrative example of the fifth embodiment of the invention shows a predetermined breaking zone 9 extending only over the cavity 5 / application channel 7, but the predetermined breaking zone 9 may also extend beyond the cavity 5 / application channel 7, in particular also over the entire width of the rim 8 and / or the application package 1 or the bottom part 3. As already explained with respect to the previous embodiments, in this case both the groove 15 and the projection 17 may extend beyond the cavity 5 / application channel 7 (as in the fourth embodiment), or only one of the groove 15 or the projection 17 may extend beyond the cavity 5 / application channel 7 (as in the third embodiment).

[0620] In addition, although according to Figure 23 to Figure 25 The illustrative example of the fifth embodiment shows the predetermined breaking zone 9 embodied as a bend / kink and / or having both a recess 15 and a projection 17, but it is also possible to provide only a recess 15 on the inner surface 18 without a projection, in particular similar to the second embodiment.

[0621] Therefore, any combination of different embodiments is possible. In particular, the fifth embodiment can be combined with any of the previous embodiments.

[0622] The molding tool 102 (in particular the molding device 102C) is preferably constructed / shaped accordingly to form the bottom part 3 (in particular the predetermined breaking zone 9) according to the fifth embodiment, that is, having a groove 15 on the inner surface 18 and / or a protrusion 17 on the outer surface 16.

Otherwise, even without repetition, the above explanations and features preferably apply accordingly or correspondingly.

[0626] If the molding device 102C is designed as an insert and / or replaceable component in the respective molds 102A, 102B, the molding device 102 can also be adapted for producing the predetermined fracture zone 9 of the fifth embodiment by interchanging such inserts, i.e., providing an insert of the female mold 102A in the male mold 102B, and vice versa.

[0627] Fig.26 and Fig. 27 An exemplary preferred embodiment of the female mold 102A of the molding tool 102 is shown in a schematic perspective view.

[0636] The ventilation holes 102H are preferably provided so that air can escape from the moulds 102A, 102B when the bottom part 3 is thermoformed, in particular deep drawn.

[0637] Specifically, when the plastic sheet 200 is pressed into and / or onto the molds 102A, 102B by negative pressure and / or positive pressure, the air between the plastic sheet 200 and the respective molds 102A, 102B escapes to the environment through the vent holes 102H. In this way, preferably, the plastic sheet 200 can be laid flat on the mold(s) 102A, 102B without any damage from the air trapped between the plastic sheet 200 and the mold(s) 102A, 102B.
