Description

The invention relates to a blister pack with the features of the preamble of claim 1 and the features of the preamble of claim 9 and a packaging unit with the features of the preamble of claim 20.

Blister packs of the type in question, which are often referred to as blister packs, serve in the pharmaceutical, ecotrophic and cosmetic sector as containers for accommodating corresponding products such as capsules, dragees, tablets, drug beads, etc. In such blister pack is the lumpy product within the cup-like upper part, the opening of which is tightly closed by the sealing film such as sealing film. The product is thus protected against environmental influences such as moisture and dirt and guarantees the consumer the durability and original condition of the packaged product.

A blister pack of the type in question is described for example in the EP 0 563 934 A1 Further information on the state of the art can also be found in the documents DE 299 07 744 U1 . DE 29 07 740 U1 . DE 43 17 326 C1 . DE 91 03 973 U1 . US Pat. No. 6,443,307 B1 and WO 98/43893 A1 just to name a few publications.
The document US 3,343,897A discloses a blister pack having the features of the preamble of claim 1.
The design of blister packs and the selection of plastic films to form the top of closure films is one of the tools of the art in packaging technology. In general, the example " Packaging Handbook 1999 ", publishing house for chemical industry, Augsburg, in particular pages 211 to 213, 388 to 413 to get expelled. Extensive explanations on the parameters involved, the plastics used, etc. are given there.

In blister packs of the type in question, the side wall of the cup-like, formed from plastic film shell is preferably formed conically and optionally adapted to the geometry of the lumpy product, which is located in the blister pack. However, this adaptation relates to the shaping of the side wall in the plane parallel to the bottom area. In the plane perpendicular thereto, so to speak in a vertical section through the blister pack, there is no particularly preferred shape, the shaping is rather rather production technology or mechanical engineering, depending on the design of the molding device.

It has been shown that in the case of a blister pack filled with a lumpy product, although the closure film is occasionally pushed through, the lumpy product nevertheless does not leave the receiving space in the upper part, but remains hanging there. This may be due to the fact that the plastic film-molded top deforms so that the outlet of the product serves to reduce the size of the opening.

The teaching is based on the problem of avoiding unintentional retention of the lumpy product in a blister pack of the type in question already by the design of the blister pack and at the same time to achieve that even pressure-sensitive lumpy products can be handled easily.

The above-indicated problem solves the teaching in a blister with the features of the preamble of claim 1 by the realization of the features of the characterizing part of claim 1. A sibling solution describes claim 9. In particular, a combination of both approaches promises optimal problem resolution.

Preferred embodiments and further developments are the subject of the claims.

According to the invention formed from a plastic film upper part of the blister pack is specifically provided with certain contours for forming one or more fold lines, which are designed and arranged such that a narrowing of the outlet of the lumpy product serving opening is avoided. At the same time, the weaknesses in the upper part formed by the crease lines reduce the force required when pushing the bottom area in the direction of the opening so that even sensitive lumpy products can be dispensed optimally with such push-through packaging.

For the design of the push-through packaging in detail, the specialist knowledge documented by the "Packaging Handbook 1999", which must also be applied in the present case, may be referred to.

Of particular importance is the blister pack according to the invention in the field of cosmetic finished products, especially hair colors, hair colorants and care products. In that regard, the blister pack according to the invention can form in a particularly advantageous manner, the dispensing device of a second partial packaging of a packaging unit for a single or multi-component end product (claim 20). By such a packaging unit, the activation by the user can be carried out in a simple manner, timed and reproducible and without risk to the user.

It is essential, first, that in the ready-to-use state, the second partial packaging is fixed to the first partial packaging. The second subpackage then covers at least partially an opening of the first subpackage with its delivery side.

Thus, the position of the second partial packaging in the ready-to-use state is precisely determined, so that the delivery of the second product component can take place directly into the unclosed opening of the first partial packaging.

Thus, upon activation of the multi-component end product, the user is forced to place the second subpackage in the predetermined position on the first subpackage. This makes the activation process reproducible and safe for the user. A contact of the user with the second product component can be avoided in any case.

Furthermore, it is particularly advantageous that the second partial packaging in the ready-to-use state at least partially covers the opening of the first partial packaging. As a result, further product components in the ready-to-use state can not be given through the opening of the first subpackage, as long as the second subpackage is fixed to the first subpackage. In order to be able to add further product components, the second partial packaging must first be detached from the first partial packaging. With a corresponding configuration of the first and the second partial packaging, it can be provided that the release of the second partial packaging from the first partial packaging corresponds to a reaction time to be observed, so that the user is forced to comply with this reaction time.

The fixing of the second partial packaging to the first partial packaging can preferably be effected by screwing, inserting, bouncing or the like. In the case of a screw is particularly advantageous that the time required for the separation of the sub-packages by the number of threads, preferably in the first sub-package, is controllable.

In a particular embodiment, the first partial packaging is resealable, preferably by a screw cap, formed. After admitting a product component in the first partial packaging, the first partial packaging can be closed again, so that mixing by shaking is possible. Only after the closure has been opened is it then possible to add further product components. As a result, a further time delay is controllable depending on the configuration of the screw cap.

In a particularly preferred embodiment, the second sub-package on a dispenser for the product component or the product components, which ausfördert in the ready state in the direction of the opening of the first sub-package. In addition to the dispensing device, a reservoir for receiving the product component or the product components is preferably provided, which ensures a portioned delivery of the product component or the product components. Depending on the design of the reservoir, it may be provided that the user selects the dosage of the product component or the product components themselves.

For the second partial packaging, in a particularly preferred embodiment, a planar section is provided which is parallel to the opening of the first partial packaging and forms a flat cover over the opening of the first partial packaging in the ready-to-use state and which preferably has the dispensing device. With such a section, on the one hand, the addition of a further product component is prevented with a fixed second partial packaging, on the other hand, a direct contact of the user with the product component in the second partial packaging is not possible.

In order to be able to attach the second subpackage to the first subpackage, the second subpackage in a preferred embodiment has at least one further section arranged parallel to the opening of the first subpackage and assumes the function of a holder. Preferably, this holding function is ensured by the fact that the sections of the second sub-packages have openings that at a projection of first partial packaging, in particular a bottleneck, are clamped in the ready state, plugged or screwed.

Particularly compact and easy to manufacture is the design of the second sub-package such that the above-mentioned portions of the second sub-package are at least partially formed in a box shape - box section.

In the event that the second partial packaging is cut and made of foldable material, it is provided that at least one edge of the second partial packaging has one or more oblong holes between the section forming the planar covering over the opening and a bent, preferably right-angled section , This offers in particular the advantage of easy folding, and a possibly desired flexibility of the material in order to prevent tearing of the surface of the second part of the package.

If the box section is closed laterally on only two opposite sides, it has a parallelogram structure and can be folded in and out. This is particularly advantageous for the ready-to-sell state of the packaging unit, since the second partial packaging is flat in the folded state and substantially strip-shaped. This embodiment is particularly advantageous if the second partial packaging consists essentially of cardboard.

The blister pack according to the invention is advantageously used together with the above-mentioned packaging unit as packaging for cosmetic finished products, in particular hair colors, hair tints, care products or the like. In a method for producing a multicomponent, at least one further product component from a second subpackage is to be added to at least one product component in a first subpackage in order to arrive at the "final" finished product.

It is intended to place the second sub-package on the dispensing side over an opening of the first sub-package, to promote the product component from the second sub-package without direct contact of this product component in the first sub-package and finally to mix both product components in the first sub-package to the finished product. It is particularly advantageous if the arrangement of the second partial packaging with the partial packaging according to the invention also allows only a dosage of the products from the first partial packaging, so that the user as required on the dosage of a single-component end product or multi-component end product as a mixture of the first partial packaging can decide. Namely, applications are conceivable in which in the second partial packaging only components are stored, leading, for example, to a higher concentration in the final product. An addition is therefore not mandatory.

Of particular importance is the application of the blister pack according to the invention in conjunction with a coloration product as is also the subject of a parallel patent application of the Applicant, patent application 102 08 874.8 "Colorants" of Mar. 1, 2002. The disclosure of this patent application is incorporated by reference into the disclosure of the present application.

With regard to the lumpy product in the blister pack in conjunction with coloration products, the disclosure content of the present patent application is finally incorporated by reference in the disclosure content of the Applicant's co-pending patent application 102 08 875.6 "Shaped body with pearlescent pigment", whose filing date is also March 1, 2002.

Of course, there are a variety of ways to design and develop the teaching of the invention. For this purpose, reference may be made to the dependent claims.

In the following the invention will now be described with reference to exemplary embodiments illustrated in the drawing. Particularly preferred embodiments and developments of the invention, as well as particular advantages of certain embodiments are also discussed in connection with the explanation of the embodiments.

A second embodiment of a packaging unit with a blister pack according to the invention,

Fig. 1 shows in a section the principle of a blister pack. This consists of a cup-like, made of a plastic film, which may also be a laminated with a metal coating film, shaped upper part 1 with a substantially radially outwardly projecting sealing flange 2 opening 3. The upper part 1 serves to accommodate a lumpy product 4, which here has spherical shape, for example, a drug bead. The opening 3 of the upper part 1 is closed by a push-through closure film 5 connected to the closure flange 2 of the upper part 1, which is preferably a metal foil or a metal / plastic composite foil or burstable plastic foil.

Fig. 1 shows for the blister pack of the prior art shown there that the molded plastic film shell 1 has the overall shape of a spherical segment, so no special structuring of the upper part 1 is provided.

Fig. 2 shows that the upper part 1 a bottom portion 6 opposite the opening 3 and between bottom portion 6 and opening 3 at least partially slightly widening in the direction of the opening 3 Side wall 7 has. Also in the embodiment in Fig. 1 one could speak of side wall 7 and bottom area 6, wherein here, however, the bottom area 6 and the side wall 7 without gradations merge into each other.

In general, it is true that this is a blister pack for only a lumpy product 4, that the teaching of the invention but also on blister packs with a plurality of juxtaposed tops 1 for receiving each a lumpy product 4 or possibly also for receiving multiple lumpy Products 4 extends. In that regard, may be made for examples on the state of the art, which has been explained at the outset.

Fig. 2 shows that the side wall 7 has a starting from the bottom portion 6, widening first wall portion 8 and an adjoining, less than the first wall portion 8 expanding, possibly not expanding, but exactly cylindrical, second wall portion 9 and that between the wall sections 8, 9 a circumferential crease line 10 is formed such that when directed in the direction of the opening 3 pressure application to the bottom portion 6 of the second wall portion 9 of the side wall 7 iw does not buckle inward. It depends on the extensibility of the plastic material of the upper part 1, to what extent the second wall section 9 displaces radially outward. In principle, however, the arrangement of the wall sections 8, 9 due to the different inclination of the wall sections 8, 9 is such that a radially outwardly directed force component is introduced from the first wall section 8 into the second wall section 9. In this way, it is achieved that, in any case, the range of movement available for the product 4 tends to be greater, not smaller. The product 4 can be caused by the pressure on the bottom portion 6 unhindered emerge from the opening 3 by pressing the sealing film 5.

The illustrated embodiment is not drawn to scale with respect to the weights, but shown understanding. This also applies to the other illustrations.

The illustrated embodiment shows that here both the first wall section 8 and the second wall section 9 thereby widen in the direction of the opening 3, that they have a conical shape or a conical contour. But this is not mandatory, even a curved course can achieve a similar effect.

Already in the prior art ( EP 0 563 934 A1 ) has been pointed out that in blister packs of the type in question without additional measures, the side wall 7 by the manufacturing process has a greater wall thickness than the bottom portion 6. According to the invention, it is now proposed that, according to a preferred embodiment, the production of the blister pack is realized such that the second wall section 9 is rigid, in particular stiffer than the first wall section 8. This ensures that the bottom region 6 with the first wall section 8 under axial pressure transmission can be pressed on the lumpy product 4 inwardly in the almost cylindrical receiving space ultimately formed by the second wall portion 9, without the second wall portion 9 folds prematurely. This also serves to maintain the movement space for the product 4 and the safe discharge of the product 4 from the opening 3.

Fig. 3 shows a further embodiment of a blister pack. Here, it is additionally provided that the second wall section 9 and here also the first wall section 8 is provided with mechanical stiffeners 11 formed in the plastic material, in particular beads, bending lines, etc. By the mechanical stiffeners 11 certain areas of the side wall 7 can be reinforced and other areas of the side wall 7 in turn be weakened, so that a certain behavior of the Side wall 7 can be realized in pressure in the axial direction of the bottom portion 6. In addition, it can be achieved by this contouring of the upper part 1 some interesting visual and design effect.

Special optical effects can be, as Fig. 3 combined with Fig. 4 shows particularly clearly, thereby achieve that the stiffeners 11 are arranged in the manner of a honeycomb structure or, as here, in the manner of a brilliant cut structure.

Especially the latter design offers particularly interesting design aspects. Here it might be advisable to make the plastic material of the upper part 1 is not transparent or translucent, but metallic shiny, for example, steamed or laminated, or even pearlescent shiny.

The in the Fig. 2 and 3 shown embodiments, moreover, that the bottom portion 6 is made flat and merges via a crease line 12 in the first wall section 8.

Due to the design of the stiffeners 11 also axially extending crease lines can be realized, as shown here. The distribution of the stiffeners 11 on both wall sections 8, 9 creates the optimal influencing possibility of the behavior of the upper part 1 when pressure is exerted on the floor area 6.

Basically, it is also conceivable that, similar Fig. 1 , the bottom portion 6 arcuately merges into the first wall portion 8, in particular with the first wall portion 8 is formed dome-shaped together. This is not shown here.

The embodiments of the 3 and 4 show, moreover, that here the second wall section 9 merges with the formation of a bending line 13 directly into the closure flange 2.

The Fig. 5 and 6 show - embodiments that are designed differently than the embodiments of the figures described above. Here, according to the sibling, an alternative descriptive claim 9 provided that the side wall 7 merges at the open edge to form a bending line 14 in an iw radially outwardly projecting annular flange 15 that the annular flange 15 at the radially outer edge in an approximately cylindrical shell portion 16 merges, which merges at its open edge to form a bending line 17 in the closure flange 2 and that when directed in the direction of the opening 3 pressure application to the bottom portion 6 of the annular flange 15 folds inward and radially outward.

Fig. 5 shows in an enlarged section the relationships in the region of the bending line 14 between the side wall 7 and the annular flange 15. The arrow indicates how the region of the bending line 14 when applying axially directed pressure on the bottom portion 6 of the upper part 1 down and outsourced. The connecting bow between the annular flange 15 and the shell portion 16 has here the function of a pivoting hinge. The arrow makes it clear that the effective for the product 4 passage opening at the level of the bending line 14 by the axial pressure on the bottom portion 6 radially tends to increase anyway. Of course, this is also dependent on the extensibility of the plastic material used. In any case, the direction of force action is clear.

It can be clearly seen that, according to the preferred teaching, the transition from the annular flange 15 to the jacket section 16 is rounded off, that is, it does not form a bending line. This promotes the controlled hinge function of this area.

For the shell section 16 has already been explained that this is an approximately cylindrical shell portion 16. This cylindrical jacket section 16 makes it possible to insert the push-through package as a whole into a circular opening of a holder consisting of cardboard, for example. This may be an opening in a cardboard strip, which is part of an overall multi-part packaging unit. Due to the manufacturing process, a slightly inclined course of the shell section 16, which slightly widening towards the opening 3, is readily realized. Appropriate and also manufacturable is also an exactly cylindrical course. Interesting is the construction even if, how Fig. 5 and 6 show, the skirt portion 16 from the opening 3 to the annular flange 15 extends slightly widening, which allows a kind of locking in an opening in a cardboard strip.

For the pharmaceutical, but in particular cosmetic, applications lying in the special field of view of the teaching, it is advisable to provide a height of 2 to 5 mm, preferably of about 3 to 4 mm, for the jacket section 16, the total height of the upper part 1 of the push-through packaging should be at 8 to 15 mm.

Fig. 5 shows an embodiment of a blister pack, in which the features of the embodiment of Fig. 2 are also realized, so the teachings of both independent claims are combined. According to shows Fig. 6, 7 an embodiment in which also the features of the embodiment of 3 and 4 are realized with. Here, too, characteristics of both stakeholders are realized.

In both exemplary embodiments, an optimal design and applicability of the blister pack according to the invention results. However, it should be noted that both embodiments can also be realized side by side and independently.

Overall, there is still a lot of interesting areas for the blister pack according to the invention with regard to the parameters that are advantageously to be realized.

First, it is recommended that the thickness of the starting plastic material of the upper part 1 (before deep drawing) is about 150 .mu.m to 600 .mu.m, preferably about 400 .mu.m, and at the kinks about 180 .mu.m to 220 .mu.m, preferably about 200 .mu.m. In the deep-drawn state, the kinks are thinner, preferably by about 30% to 60% thinner than the wall material. This applies in any case for typical plastic films made of PE, PP, PS, PET; PVC / PVDC, PVC / PFC etc. (see the specialist literature and patent specifications mentioned in the beginning).

Furthermore, it is recommended that the sealing film 5 is designed as a metal foil, as a multilayer foil using metal and / or plastic and / or paper, as a burstable plastic film or as a paper foil.

With regard to the thickness of the sealing film 5 is a wide range. For metal foils, in particular aluminum foils, a preferred range of 15-20 μm results. Penetration forces of the sealing film 5 according to DIN 53142 in the range of 10 to 20 N are equally recommended. A typical aluminum composite foil defines a force of 15 N.

The illustrated and preferred embodiment shows the design of the lumpy product 4 as a spherical solid (pearl). This is not mandatory, but particularly appropriate. For the rest may here especially on the already mentioned DE 102 08 875.6 be pointed out. It is also possible to stock other dosage forms such as gels, menthols, granules or liquids, but these must be flowable. The blister pack is then equipped with ensprechenden means that cause a breach of the sealing film.

Particularly interesting parameter ranges for certain dimensions result in such a way that the lumpy product 4 has a fracture hardness of 50 to 120 N, in particular of at least about 60 N and / or that the lumpy product 4 has a diameter of 5 to 10 mm, in particular from 8 to 9 mm and / or that the lumpy product has a weight of 200 mg to 600 mg, in particular of about 400 mg.

For the formation of various surfaces by stiffeners 11 and crease lines 6 to 10, preferably 8 surfaces, in the second wall section 9 16 to 30, preferably 24 surfaces are exemplified in the illustrated embodiments in the first wall section. For the rest may in individual on the already mentioned DE 102 11 303.3 to which reference is also hereby incorporated by reference.

It has already been pointed out that the claimed blister pack is particularly recommended for a lumpy product 4, which is merely a component of a multi-component overall product, in particular a cosmetic finished product. In particular, the lumpy product 4 in the blister pack according to the invention is a coloration product, in particular the color component of a multi-component hair dye or hair tinting agent or a component of a hair care product. The blister pack according to the invention allows a secure, non-contact and fast introduction of the component into the component receiving product.

Particularly suitably applicable is the blister pack described in connection with a in the 8 to 11 illustrated packaging unit. Fig. 8 shows a side view of such a packaging unit for a multi-component end product, which consists of several separate sub-packages 21, 22, wherein on a first sub-package 21 with at least one Product component, a second sub-package 22 with at least one further product component can be fixed and the second sub-package 22 with its delivery side 23 for the at least one further product component, an opening 24 of the first sub-package 21 at least partially covered. It can be seen here the blister pack according to the present patent application as a dispenser 26 in the upper region of the second sub-package 22nd

Not shown is the ready for sale condition of the packaging unit. For sale, the individual sub-packages 21,2 are arranged in a higher-order packaging, in particular a folding box. It may be pointed out that the second partial packaging is not necessarily fixed exclusively in the ready-to-use state of the first partial packaging, but that it can also be provided that the second partial packaging is already fixed to the first partial packaging when ready for sale. Then there is no superordinate packaging and the loss of the partial packaging is prevented.

When ready for sale, the first partial packaging 21 has a closed opening 24. The opening 24 may be closed by a threaded screw cap 25 and / or by a foil. The second sub-package 2, which is preferably releasably securable to the first sub-package 21, can be defined in a particular embodiment by screwing, plugging, bouncing or the like. On the first sub-package.

It when the first sub-package 21 has a thread 25 to which the second sub-package 2 is screwed is particularly advantageous. In addition to a robust connection between the second partial packaging 2 and the first partial packaging 21, this also ensures that the time required for the separation of the partial packaging can be controlled by the number of threads. This takes account of the fact that in certain cases very specific, process-related waiting times have to be met before For example, further product components may be added to the first sub-package 21.

In a preferred embodiment, the first sub-package 21 is designed resealable. Thus, after adding a product component, sealing and mixing by shaking is possible. Depending on the configuration of the corresponding closure in turn certain waiting times are controlled here.

In the embodiment according to Fig. 8 . Fig. 11 If the first partial packaging 21 is bottle-shaped, other shapes may also be provided.

In the present case, the second partial packaging 2 has a dispensing device 26 for the product component or the product components 4, which in the in Fig. 8 shown ready-to-use state in the direction of the opening 24 of the first sub-package 21 promotes. It can be clearly seen that, with this arrangement of a dispenser 26, contact between the user and the product component 4 contained in the second subpackage 2 is impossible since the second subpackage 2 virtually closes the opening 24 of the first subpackage 21. The dispensing of the product component 4 by the dispenser 26 may occur directly in the unlocked opening 24 of the first sub-package 21.

In the case of closure of the opening 24 of the first sub-package 21 by a film, it is provided in a further preferred embodiment, the film by means of the dispenser 26, additional means such as spikes and / or a solid-like product component to pierce, so that the product component through the opening 24th can be delivered.

The second sub-package 2 has a reservoir 27 for receiving the product component or the product components. Depending on the design the reservoir 27 is a tailored to the particular application, portioned delivery of the product component or the product components guaranteed. For example, provision may also be made for the reservoir 27 to be divided into individual reservoirs 27, so that the user himself can determine the dosage of the product component.

It can also be provided that the second sub-package 2 is reclosable, so that further Dosiermöglichkeiten are given. In addition, depending on the product component, an environmentally sound disposal is possible without chemicals can escape uncontrollably from the reservoir 27. For example, the second part of the package 2 as a blister strip with the above-described blister pack with it packaged separately and separately dosed liquid, solid (particulate, powdered, granular), pasty or gel-like product components.

In a further preferred embodiment, it is provided that the second sub-package 2 has at least one flat arranged parallel to the opening 24 of the first sub-package 21 section 28, which, as in Fig. 8 shown, in the ready state, a flat cover over the opening 24 of the first part of the package 21 forms. A dispenser 26 and possibly a reservoir 27 is now preferably arranged on the above-mentioned section 28, that it discharges in the direction of the opening 24 of the first sub-package 21.

For fastening and unambiguous positioning of the second sub-package 2 on the first sub-package 21, it is now provided that the second sub-package 2 has, in addition to the above-mentioned section 28, at least one further section 29, 30, which assumes the function of a holder. For this purpose, the section 29, 30 an opening 21, 32, which is clamped to a projection such as neck of the first sub-package 21 in the ready state, plugged or screwed. The diameter of the Opening 21,32 is largely arbitrary, provided that it is adapted to the diameter of the projection of the first sub-package 21. Preferably, the diameter moves within 20mm to 30mm. Depending on the application, additional parallel sections may be provided to support the holding function. A preferred number of sections here are two sections, but up to five sections may be provided, in some cases more sections may be provided.

A further stabilization of the second sub-package 22 on the first sub-package 21 is achieved in that the opening 21, 32 of the portion 29, 30 which surrounds the opening 24 of the first sub-package 21 in the manner of a sleeve, slightly smaller in diameter than the outer diameter of the Opening 24 is. The resulting effect is that the second sub-package 22 can be applied all together tightly on the opening 24. If the opening 24 has an external thread 25, then there is the additional advantage that with a corresponding configuration of the section 29, 30, the second partial package 22, so to speak engages and optionally also an audible snapping takes place.

A particularly simple attachment of the second sub-package 22 to the first sub-package 21 results from the fact that the openings 21, 32 of the sections 29, 30 of the holder in the ready state to the opening 24 of the first sub-package 21 are substantially centered.

In a preferred embodiment, the sections 28, 29, 30 of the second sub-package 22 in the ready-to-use state are substantially box-shaped. In a particularly preferred embodiment, the second sub-package 22 three sections 28, 29 30, of which in the ready state, a section 28 a flat cover over the opening 24 of the first sub-package 21 and two sections 29, 30 form a holder on the first sub-package 21 , It is further provided that all sections 28, 29, 30 form a box section 34. The mentioned box shape of the second Partial packaging 22 leads both to a high mechanical stability and to a particularly compact design, as will be shown below.

The above-mentioned, a flat cover over the opening 24 of the first sub-package 21 forming portion 28 is formed in a preferred embodiment of two parallel superimposed layers, preferably made of cardboard. In this embodiment, it is advantageous to clamp at least a part of the dispensing device 26 between the two layers 28,28. As a result, additional fastening measures for the dispensing device 26, for example, the sticking of the dispensing device 26 may be dispensed with, if necessary. If now, as in Fig. 8 and Fig. 9 shown, the box portion 34 laterally on only two opposite sides 35, 36 has a closed structure, the box portion 34 can be set up or folded flat. In this case, it has been exploited that the second partial packaging 22 is "missing" in the non-attached state, so that the second partial packaging 22 can only be stable in the ready-to-use state and is otherwise collapsible. This parallelogram structure of the box section 34 in the middle illustration of FIG Fig. 9 to recognize.

In a further preferred embodiment, the second sub-package 22 on an elongated portion 37 which fulfills various functions. First, it can be used in the sense of a lever for the fine alignment of the dispensing device 26 over the opening 24 of the first sub-package 21. With a suitable embodiment of the elongated portion 37, the elongated portion 37 may also act stabilizing. Furthermore, the elongated portion 37 may be printed with usage hints, with a company logo or the like. It may further be provided, preferably to provide on the back of the elongated portion 37 necessary warnings or contents. It can also be provided to equip the elongate portion 37 with a pocket for receiving instructions for use o. The like., Which are inserted into the pocket.

With a corresponding embodiment of the elongate portion 37, it is possible that the second partial package 22 is formed in a substantially strip-shaped overall when the box section 34 is folded. This is particularly advantageous, in particular for the ready-to-sell state of the packaging unit, since hereby an optionally existing, higher-order packaging in the form of a folding box can be very small.

In a further embodiment, which leads to a particularly simple production of the second partial packaging 22, it is provided to cut and produce the second partial packaging 22 from a layer of foldable material, in particular cardboard. The settlement of such a situation for the embodiment Fig. 8 and Fig. 9 shows Fig. 10 , The processing is divided particularly cleverly by the sections 30, 28, 35, 29, 37, 37, 36, 28 following each other. By repeating section 37, the overlapping of the layers 28, 28 becomes possible.

In order to ensure easy folding and possibly to avoid tearing the surface of the second sub-package 22, an edge of the second sub-package 22 between section 28 and a bent, preferably arranged at right angles, section provided with one or more slots. The ratio of full to open space here is 3: 1 to 1: 3, preferably 1: 1. In a preferred embodiment exactly two slots are provided here.

The configuration of the second sub-package 22 is not on the in Fig. 8 and in Fig. 9 illustrated embodiment limited. For example, it can also be provided that the second sub-package 22 has a clamping bracket 38, which is connected via a connecting part 39 with the planar cover over the opening 24 of the first sub-package 21 forming section 28. The second sub-package 22 is then through the clamp 38 at the first sub-package 21 can be fixed and ensures the centering of the section 28 and thus possibly the dispensing device 26 (FIG. Fig. 11 ).

The second sub-package 22 may be executed depending on the field of application in different materials. Examples include cardboard, corrugated cardboard or plastic. The dimensions of the second sub-package 22 are largely arbitrary. A preferred dimension here is 150mm * 80mm (length * width).

For the configuration of the dispenser 26 and the reservoir 27, a number of possibilities are provided. In a preferred embodiment, a dispenser 26 is provided with a reservoir 27 containing the product component 4 ( Fig. 3 . 6 ). The reservoir 27 has an opening 3, which is closed in the non-activated state of the second partial packaging 22 with a sealing film 25. For delivery of the product component 4, only a pressure on the upper part 1 of the reservoir 27 is required. The pressure is transmitted via the product component 4 located in the reservoir 27 to the sealing film as a sealing film 5, which is broken as a result of the pressure load. As a result, the product component 4 is released and falls first through the opening 3 of the reservoir 27 and then through the opening 24 of the first sub-package 21 therethrough.

In the present case, this is particularly advantageous in the case of the above-mentioned clamping attachment of the dispensing device 26 between two parallel superimposed layers 28, 28. The upper part 1 may consist of PVC, PP, PET, PS and / or a combination of these components. The sealing film 5 consists essentially of aluminum, preferably with a plastic coating as the sealing medium. The force required to pierce the sealing film is preferably 15 N (DIN 53142).

The product components provided in the two subpackages 21, 22 can assume various configurations. The second Partial packaging 22 provided product component 4 is lumpy, powdery, liquid, pasty or gel, in a preferred embodiment pieces or powdered, while provided in the first sub-package 21 product component is liquid or gel. In a particular embodiment, the lumpy product component 4 is designed rotationally symmetrical, in particular lenticular, spherical, ellipsoidal or cylindrical with rounded end faces.
