Abstract

The invention relates to a packing unit for a single or multi-component end product, made from a plurality of separate partial packages (1, 2). A second partial packaging (2) with at least one other product component can be fixed to a first partial packaging (1) with at least one production component. According to the invention, the second partial packaging (2) is fixed to the first partial packaging (1) in a ready-to-use state and the second partial packaging (2) at least partially covers an opening (4) of the first packaging (1) with the output side thereof (3) for the at least one other product component.

Description

The invention relates to a packaging unit for a one- or multi-component end product according to the preamble of claim 1 and a use of this packaging unit. Such a packaging unit is from the document FR 1591549 A known.

Multi-component end products are known from the cosmetics sector, from the adhesive area or from the painting area ( DE 102 08 874 . DE 102 08 875 ). Here it is often the case that the individual components may only be brought into contact with each other shortly before use in order to avoid undesired chemical reactions. The packaging unit then has essentially three functions: First, the packaging unit ensures a separate transport and storage facility for the individual product components. Next, the packaging unit is designed visually so that it gives an attractive and sales-promoting impression in the shop. Finally, the packaging unit typically also provides a means for contacting the product components in a predetermined manner prior to use. This process is called activation in the following.

It is therefore to be distinguished here between the ready-to-sell state of the multicomponent end product on the one hand, in which the individual product components are separated from one another, and the ready-to-use state, on the other hand, in which the multicomponent end product has been activated.

Packaging units for the abovementioned multicomponent end products therefore generally consist of several separate subpackages. In order to enable easy handling of the various product components, a second partial packaging with at least one further product component can be fixed to a first partial packaging with at least one product component.

The known packaging unit for a two-component product, from which the invention proceeds, has a bottle-shaped first sub-package for receiving a first product component and a second sub-package in the form of a crowner for receiving a second product component. The Crowner is realized here as a cardboard sleeve, which is already plugged in ready for sale on the opening of the bottle-shaped first part of the package. An ampoule containing the second product component is provided on the second subpackage, which is detached from the second subpackage prior to use and its content is added to the opening of the first subpackage (activation).

Particularly in the case of multi-component end products in which individual product components must not be touched, the known packaging unit does not offer a satisfactory solution. Basically, there is a risk that the user when opening the ampoule or when filling in contact with at least the second product component. Moreover, with the above-mentioned packaging unit "pasting" of the second product component can not be completely avoided.

From the publication DE 2 329 704 A1 a container system consisting of two bottles is known, wherein one bottle is closed with a membrane or a valve and the other bottle has a pin in the form of a tip 30 for piercing the membrane or for opening the valve. For use, the two separate bottles are connected together and then a product is transferred by manual deformation of the bottle to the other product in the other bottle. The disadvantage is that in the salable state, the two bottles are present separately and are connected to each other only during use. During storage and transport, part of the container system may be lost.

Furthermore, two-component packages are known, for example from the document DE 25 39 291 A1 the Applicant, which consists of a main component receiving one-piece mixing container and the additional component receiving head container, a molded on the bottom of the mixing container, detachable application tip and the piercing of the formed as a release film bottom of the head container and reaching into the vicinity of the bottom mandrel exists. Such a package has the disadvantage that in the ready state no demand-dependent quantity metering can be made, because the mixing container and the head container are permanently connected to each other. This packaging is only suitable for stocking two-component products and does not allow use for a single component.

In certain cases, the activation is also subject to time limits and waiting times, which may correspond to the reaction times of the respective product components. For example, it may be necessary to wait a certain amount of time after adding a product component before continuing the activation by adding further product components. If these reaction times are not met, activation may even fail depending on the application.

With the known packaging unit, such waiting times can not be influenced. For example, it is possible for the user to add further product components through the opened opening immediately after adding a first product component, even if an above mentioned waiting time of a few seconds or the like may be predetermined. Waiting times of 0.2 to 30 seconds are common here.

As a result, the known packaging unit offers an expensive and uncertain possibility for the user of activating the multi-component end product with only little reproducibility of the activation process. Further, the packages described in the prior art are intended for pre-use two-component products, but are not suitable as packages for the separate storage of components, of which at least one could be used without the other component. An individual dosage by the user is impossible.

The present invention is based on the problem, the known packaging unit to design and develop such that a packaging technically favorable overall solution arises and the implementation of the activation by the user in a simple manner, timed and reproducible and without risk to the user is possible.

The present problem is first solved by a packaging unit according to claim 1.

By fixing the second sub-package to the first sub-package in the salable condition ensures that both sub-packages are permanently but releasably connected together and therefore no component can be lost. Further, the invention provides that in the ready state, a dosage of the product from the first sub-package is also possible if the second sub-package is disposed on the first sub-package. This provides the user with a multitude of possibilities for using the packaging unit according to the invention, such as single-component dosing from the first or second partial packaging, multi-component dosing from the second partial packaging or demand-dependent dosing of the components from the second partial packaging into the first partial packaging.

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 embodiment of the first and the second partial packaging, it can be provided that the Solving the second sub-package of the first sub-package corresponds to a response time to be respected, 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 closure formed. After adding a product component in the first sub-package, the first sub-package 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 design 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 sections of the second sub-packages having openings which are clamped to a projection of the first sub-package, in particular a bottle neck, ready for use, 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 elongated holes between the portion forming the planar cover over the opening and a bent, preferably right-angled portion , 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.

A particularly simple implementation of the activation process according to the invention is given when the dispensing device is formed by a blister packaging, preferably by a push-through or press-through blister packaging. Then the user's activity is reduced to impressing the blister unit. This recourse to a packaging technique known from the prior art also reduces the production costs.

It has been found that in the case of conventional blister packs 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 is due to the fact that the formed plastic film upper part deformed so that the outlet of the product serving opening is reduced.

The above-identified problem solve blister packs according to the invention, wherein unintentional retention of the lumpy product in a blister pack is already avoided by the design of the blister pack and at the same time is achieved that even pressure-sensitive chunky products can be handled easily.

Preferably, the formed from a plastic film upper part of the blister pack is specifically provided with certain contours to form one or more fold lines, which are designed and arranged in such a way that a narrowing of the outlet of the lumpy product serving opening is avoided. The weaknesses in the upper part formed by the crease lines at the same time put the Kraftautwand down when pushing the bottom portion in the direction of the opening, so that even sensitive particulate products can be dispensed optimally with such blister packaging.

For the design of the blister pack in detail may otherwise on the by the " Packaging Handbook 1999 ", publishing house for chemical industry, Augsburg, in particular pages 211 to 213, 388 to 413 documented expertise, which is also applicable in the present case.

Of particular importance is the blister pack in the field of cosmetic finished products, especially hair colors, hair dyes and toiletries. In that regard, the blister pack according to the invention can form in a particularly advantageous manner, the dispenser of a second partial packaging of a packaging unit for a multi-component end product (claim 1).

The packaging unit according to the invention can be used particularly advantageously for producing a multi-component end product. It is essential here that for at least one product component in a first partial packaging, at least one further product component from a second partial packaging is to be added in order to arrive at the "final" finished product. According to the invention, it is provided to place the second sub-package on the dispensing side over an opening of the first sub-package, to convey 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.

Finally, the use of the above-mentioned packaging unit is claimed as packaging for cosmetic finished products, in particular hair colors, hair tints, care products or the like.

Special significance has the application of the packaging unit according to the invention in conjunction with a coloration product as it is also the subject of a parallel patent application of the Applicant, patent application DE 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 packaging unit according to the invention 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 DE 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.

Fig. 1 shows a side view of the packaging unit according to the invention for a single- or multi-component end product comprising a first partial package 1 with at least one product component and a second partial package 2 with at least one further product component. In this case, the second partial packaging 2 can be releasably fixed to the first partial packaging 1. Fig. 1 shows the ready-to-use state of the packaging unit, in which the second sub-package 2 is fixed to the first sub-package 1. The second partial packaging 2 covers with its discharge side 3, the opening 4 of the first partial packaging. 1

Not shown is the ready for sale condition of the packaging unit. For sale, the individual sub-packages are 1.2 arranged in a parent package, in particular a carton. When ready for sale, the first partial packaging 1 has a closed opening 4. The opening 4 may be closed by a threaded screw 5 and / or by a film.

The second sub-package 2, which is preferably releasably fixable to the first sub-package 1 can be defined in a particular embodiment by screws, jacks, bouncing or the like. On the first sub-package.

It is particularly advantageous if the first partial packaging 1 has a thread 5 onto which the second partial packaging 2 can be screwed. In addition to a robust connection between the second partial packaging 2 and the first partial packaging 1, 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 must be met before, for example, further product components can be added to the first sub-package 1.

In a preferred embodiment, the first partial packaging 1 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 in Fig. 1 If the first partial packaging 1 is bottle-shaped, other shapes may also be provided.

In the present case, the second partial packaging 2 has a dispensing device 6, such as a Druchdrückverpackung according Fig. 5 to 11 , for the product component or the product components used in the in Fig. 1 shown ready-to-use state in the direction of the opening 4 of the first sub-package 1 ausfördert. It can be clearly seen that with this arrangement of a dispenser 6, a contact of the user with the product component contained in the second sub-package 2 is impossible, since the second sub-package 2, the opening 4 of the first sub-package 1 quasi closes. The dispensing of the product component by the dispenser 6 can occur directly in the unlocked opening 4 of the first sub-package 1.

If the opening of the first partial packaging is closed by a film, in a further preferred embodiment, not shown, it is intended to puncture the film by means of a cutter / tappet provided on the dispenser or even a solid-like product component, so that the product component is dispensed through the opening can be. Such dispensing devices are familiar to those skilled in the art, for example, a blister pack is in the document US 6,443,307 B1 described.

The second partial packaging 2 has a reservoir 7 for receiving the product component or the product components. Depending on the configuration of the reservoir 7, a portioned delivery of the product component or of the product components tailored to the respective application is ensured. For example, it can also be provided that the reservoir 7 is divided into individual reservoirs 7, so that the user can determine the dosage of the product component itself.

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, environmentally sound disposal is possible without chemicals being able to escape from the reservoir 7 in an uncontrolled manner. By way of example, the second partial packaging can be designed as a blister strip with individual, liquid, solid or gelatinous product components packaged separately and to be metered separately.

In a further preferred embodiment, it is provided that the second sub-package 2 has at least one plane arranged parallel to the opening 4 of the first sub-package 1 section 8, which, as in Fig. 1 shown, in the ready state, a flat cover over the opening 4 of the first part of the package 1 forms. A dispenser 6 and possibly a reservoir 7 is now preferably arranged on the above-mentioned section 8 so that it conveys in the direction of the opening 4 of the first sub-package 1.

For fastening and unambiguous positioning of the second sub-package 2 on the first sub-package 1, it is now provided that the second sub-package 2 has, in addition to the above-mentioned section 8, at least one further section 9, 10, which assumes the function of a holder. For this purpose, the section 9, 10 an opening 11, 12, which is clamped to a projection 13 of the first sub-package 1 in the ready state, plugged or screwed. The diameter of the opening 11,12 is largely arbitrary, if this is adapted to the diameter of the projection 13 of the first partial packaging 1. 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 2 on the first sub-package 1 is achieved in that the opening 11, 12 of the portion 9, 10 which surrounds the opening 4 of the first sub-package 1 in the manner of a sleeve, slightly smaller in diameter than the outer diameter of the Opening 4 is. The resulting effect is that the second part of the package 2 can muster a total of tight on the opening 4. If the opening 4 has an external thread 5, then there is the additional advantage that with a corresponding configuration of the section 9, 10, the second partial packaging 2, as it were, engages and optionally also an audible snapping takes place.

A particularly simple attachment of the second sub-package 2 to the first sub-package 1 results from the fact that the openings 11, 12 of the sections 9, 10 of the holder in the ready state to the opening 4 of the first sub-package 1 are substantially centered.

In a preferred embodiment, the sections 8, 9, 10 of the second sub-package 2 in the ready-to-use state are substantially box-shaped. In a particularly preferred embodiment, the second sub-package 2 three sections 8, 9 10, of which in the ready state, a section 8 a flat cover over the opening 4 of the first sub-package 1 and two sections 9, 10 form a holder on the first sub-package 1 , It is further provided that all sections 8, 9, 10 form a box section 14. Said box shape of the second sub-package 2 leads to both a high mechanical stability as well as a particularly compact design, as will be shown below.

The above-mentioned, a flat cover over the opening 4 of the first partial packaging 1 forming portion 8 is formed in a preferred embodiment of two parallel superimposed layers, preferably of cardboard. In this embodiment, it is advantageous to clamp at least a part of the dispensing device 6 between the two layers 8,8. As a result, if necessary, further fastening measures for the dispensing device 6, for example, the sticking of the dispensing device 6, can be dispensed with. If now, as in Fig. 1 and Fig. 2 shown, the box section 14 laterally on only two opposite sides 15, 16 has a closed structure, the box section 14 can be set up or folded flat. In this case, it has been exploited that the second partial packaging 2 is "missing" in the non-attached state, so that the second partial packaging 2 can only be stable in the ready-to-use state and otherwise collapsible. This parallelogram structure of the box section 14 is particularly clear in the middle illustration of FIG Fig. 2 to recognize.

In a further preferred embodiment, the second partial packaging 2 has an elongated portion 17 which fulfills various functions. First, it is in the sense of a lever for fine alignment of the dispenser 6 on the opening 4 of the first part of the package 1 available. With a suitable embodiment of the elongate portion 17, the elongate portion 17 may also act stabilizing. Furthermore, the elongate portion 17 can be printed with usage instructions, with a company logo or the like. It may further be provided, preferably on the back of the elongated portion 17 to provide necessary warnings or contents. It can also be provided to equip the elongated portion 17 with a pocket for receiving instructions for use o. The like., Which are inserted into the pocket.

With a corresponding embodiment of the elongated portion 17, it is possible that the second partial package 2 is formed in total when folded box section 14 is substantially strip-shaped. 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.

According to the invention, which leads to a particularly simple production of the second partial packaging 2, it is provided to cut and produce the second partial packaging 2 from a layer of foldable material, in particular cardboard. The settlement of such a situation for the embodiment Fig. 1 and Fig. 2 shows Fig. 3 , The processing is particularly cleverly divided by the sections 10, 8, 15, 9, 17, 17, 16, 8 successive. By repeating section 17, the superposition of the layers 8, 8 is possible.

In order to ensure easy folding and possibly to avoid tearing the surface of the second sub-package 2, an edge of the second sub-package 2 between section 8 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 design of the second sub-package 2 is not on the in Fig. 1 and in Fig. 2 illustrated embodiment limited. For example, it can also be provided that the second partial packaging 2 has a clamping bracket 18, which is connected via a connecting part 19 with the area covering the opening 4 of the first partial packaging 1 forming section 8. The second sub-package 2 can then be fixed by the clamp 18 to the first sub-package 1 and provides for the centering of the section 8 and thus possibly the dispenser 6 (see. Fig. 4 ).

The second sub-package 2 may be performed depending on the field of application in different materials. Examples include cardboard, corrugated cardboard or plastic. The dimensions of the second partial packaging 2 are largely arbitrary. A preferred dimension here is 150mm * 80mm (length * width).

For the embodiment of the dispenser 6 and the reservoir 7, a number of possibilities are provided. In a preferred embodiment, a dispensing device 6 is provided with a reservoir 7 containing the product component 22 (cf. Fig. 5 ). The reservoir 7 has an opening 20, which is closed in the non-activated state of the second partial packaging 2 with a sealing foil 21. To deliver the product component 22, only a pressure on the upper part 23 of the reservoir 7 is required. The pressure is transmitted via the product component 22 located in the reservoir 7 to the sealing film 21, which is broken as a result of the pressure load. As a result, the product component 22 is released and falls first through the opening 20 of the reservoir 7 and then through the opening 4 of the first sub-package 1 therethrough.

In a particularly preferred embodiment, the dispensing device 6 and the reservoir 7 by a known from the prior art blister packaging or further developed Druchdrückverpackungen according to Fig. 6 to 11 educated. Possible embodiments are here, for example, a push-through or press-through-blister packaging. In addition to an upper part 23 and a sealing foil 21, the known blister packs have an edge 24. In the present case, this is particularly advantageous in the case of the above-mentioned clamping attachment of the dispensing device 6 between two parallel superimposed layers 8, 8. The top 23 may be made of PVC, PP, PET, PS and / or a combination of these components. The sealing film or closure film 21 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 (measured according to DIN 53142).

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 1, but that it can also be provided that the second partial packaging 2 is already fixed to the first partial packaging 1 when ready for sale.

The product components provided in the two subpackages can have different consistencies, such as solid or liquid. The product component arranged in the second partial packaging 2 is either lumpy or powdery or liquid or pasty or gel-like, it is essential that it can easily be applied by pressure or by gravity. In a preferred embodiment, the product 22 stored in the second partial packaging is lumpy or powdery, while the product component provided in the first partial packaging 1 is preferably liquid or gel. In a particular embodiment, the lumpy product component 22 is configured rotationally symmetrical, in particular lenticular, spherical, ellipsoidal or cylindrical with rounded end faces, whereby damage during improper handling is prevented.

Provided is a strength (breaking hardness) of the lumpy product component 22 of 50 N to 120 N and a pressing force of 2 kN to 4 kN. The weight of the lumpy product component 22 is preferably between 200 and 600 mg. The size of a spherical particulate product component 22 is provided with a diameter of 5 to 10 millimeters.

The packaging unit according to the invention for product components which are components of cosmetic finished products, in particular hair colors, hair colorants and / or care products, can be used particularly advantageously.

The sub-packaging claimed according to another teaching corresponds to the second sub-package 2 described above. Reference may be made to the corresponding explanation.

In addition to the above-described packaging unit and the partial packaging, a method for producing a multi-component end product is claimed in a further teaching.

It is essential here that to achieve the ready-to-use state, the second sub-package 2 is placed on the discharge side over an opening 4 of the first sub-package 1, the product component is conveyed from the second sub-package 2 without direct contact of this product component in the first sub-package 1 and both product components in the first partial packaging 1 are mixed to the finished product.

In a preferred embodiment, it is provided that the two sub-packages 1, 2 are separated after the addition of the product components, wherein the separation process corresponds to the reaction time of the product components. The separation process takes a period of 0.2 to 30 seconds, preferably 15 seconds.

Fig. 5 shows in a section the principle of a blister pack. This consists of a cup-like, of a plastic film, which may also be a laminated with a metal coating film, shaped upper part 23 with a substantially radially outwardly projecting sealing flange 24 opening 20. The upper part 23 is used for receiving a lumpy product 22, which here has spherical shape, for example, a drug bead. The opening 20 of the upper part 23 is closed by a push-through sealing film 21 which is connected to the closure flange 24 of the upper part 23 and which is preferably a metal foil or a metal / plastic composite foil or burstable plastic foil.

Fig. 5 shows that the formed from plastic film upper part 23 has the overall shape of a spherical segment, so no special structuring of the upper part 23 is provided.

Fig. 6 shows that the upper part 23 has a bottom region 26 opposite the opening 20 and between the bottom region 26 and the opening 20 has a side wall 27 which widens slightly at least in regions in the direction of the opening 20. Also in the embodiment in Fig. 5 one could speak of side wall 27 and bottom portion 26, in which case, however, pass over the bottom portion 26 and the side wall 27 without gradations.

In general, it is true that this is a blister pack for only a lumpy product 22, that the teaching of the invention but also on blister packs with a plurality of juxtaposed or stacked tops 23 for receiving each a lumpy product 22 or possibly also for receiving several lumpy products 22 extends. In that regard, may be made for examples on the state of the art, which has been explained at the outset.

Fig. 6 shows now that the side wall 27 has a starting from the bottom portion 26, widening first wall portion 28 and an adjoining, less than the first wall portion 28 widening, possibly not bulging, but exactly cylindrical, second wall portion 29 and that between the wall sections 28, 29 a circumferential bend line 30 is formed such that when directed in the direction of the opening 20 pressure application to the bottom portion 26 of the second wall portion 29 of the side wall 27 iw does not kink inward. It depends on the extensibility of the plastic material of the upper part 23, to what extent the second wall section 29 displaces radially outwards. In principle, however, the arrangement of the wall sections 28, 29, due to the different inclination of the wall sections 28, 29, is such that a radially outwardly directed force component is introduced from the first wall section 28 into the second wall section 29. This ensures that at least tends to the 22 available for the product movement space bigger, not smaller. The product 22 may be caused by the pressure on the bottom portion 26 unhindered emerge from the opening 20 by pushing the film 21.

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 portion 28 and the second wall portion 29 thereby widen in the direction of the opening 20 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 27 by the manufacturing method has a greater wall thickness than the bottom portion 26. According to the invention, it is now proposed that, according to a preferred embodiment, the production of the blister pack is realized in such a way that the second wall section 29 is rigid, in particular stiffer than the first wall section 28. This achieves that the bottom region 26 with the first wall section 28 under axial pressure transmission can be pressed onto the lumpy product 22 inwardly in the almost cylindrical receiving space ultimately formed by the second wall section 29, without the second wall section 29 collapsing prematurely. This also serves to maintain the movement space for the product 22 and the safe discharge of the product 22 from the opening 20.

Fig. 7 shows a further embodiment of a blister pack. Here, it is additionally provided that the second wall portion 29 and here also the first wall portion 28 with molded in the plastic material mechanical Stiffeners 31, in particular beads, creases, etc., is provided. By means of the mechanical stiffeners 31, certain areas of the side wall 27 can be reinforced and other areas of the side wall 27 can be weakened again so that a certain behavior of the side wall 27 can be realized on the floor area 26 under pressure in the axial direction. In addition, it can be achieved by this contouring of the upper part 23 some interesting visual and design effect.

Special optical effects can be, as Fig. 7 combined with Fig. 8 shows particularly clearly, thereby achieve that the stiffeners 31 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 23 is not transparent or translucent, but metallic shiny, for example, also steamed or laminated, or even pearlescent shiny.

The in the Fig. 6 and 7 Otherwise, the illustrated embodiments show that the floor area 26 is flat and transitions over a bend line 32 into the first wall section 28.

The design of the stiffeners 31 can also realize axially extending crease lines, as shown here. The distribution of the stiffeners 31 on both wall sections 28, 29 creates the optimal possibility of influencing the behavior of the upper part 23 when pressure is exerted on the floor area 26.

Basically, it is also conceivable that, similar Fig. 5 , the bottom portion 26 arcuately merges into the first wall portion 28, in particular with the first wall portion 28 is formed dome-shaped together. This is not shown here.

The embodiments of the FIGS. 7 and 8 show, moreover, that here the second wall portion 29 merges with the formation of a bending line 33 directly into the closure flange 2.

The Fig. 9 and 10 show embodiments that are designed differently than the embodiments of the figures described above. Here, according to the sibling, an alternative descriptive claim 45 is provided that the side wall 27 merges at the open edge to form a bend line 34 in an iw radially outwardly projecting annular flange 35 that the annular flange 35 at the radially outer edge in an approximately cylindrical shell portion 36 merges, which merges at its open edge to form a bending line 37 in the closure flange 2 and that when directed in the direction of the opening 20 pressure exerting on the bottom portion 26 of the annular flange 35 buckles inward and radially outward.

Fig. 9 shows in an enlarged section the relationships in the region of the crease line 34 between the side wall 27 and the annular flange 35. The arrow indicates how the region of the crease line 34 when applying axially directed pressure on the bottom portion 26 of the upper part 23 downward and outsourced. The connecting bow between the annular flange 35 and the shell portion 36 has here the function of a pivoting hinge. The arrow makes it clear that the effective for the product 22 passage opening at the level of the bending line 34 by the axial pressure on the bottom portion 26 tends to increase radially 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 a preferred teaching, the transition from the annular flange 35 to the skirt section 36 is rounded, that is, does not form a bending line. This promotes the controlled hinge function of this area.

For the shell portion 36 has already been explained that this is an approximately cylindrical shell portion 36. This cylindrical shell portion 36 allows the blister pack to be inserted in total into a circular opening of a holder made of, for example, cardboard. 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, slightly widening course of the shell section 36 towards the opening 20 is readily realized. Appropriate and also manufacturable is also an exactly cylindrical course. Interesting is the construction even if, how Fig. 8 and 9 show, the skirt portion 36 from the opening 20 to the annular flange 35 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 application of the teaching, it is advisable to provide a height of 2 to 5 mm, preferably of about 3 to 4 mm for the shell section 36, wherein the total height of the upper part 23 of the blister pack should be at 8 to 15 mm.

Fig. 9 shows an embodiment of a blister pack, in which the features of the embodiment of Fig. 6 are also realized, so the teachings of both independent claims are combined. According to shows 10, 11 an embodiment in which also the features of the embodiment of Fig. 7, 8 are realized with. Here, too, characteristics of both stakeholders are realized.

In both embodiments according to Fig. 6 to 11 results in an optimal design and usability of the blister pack. Nevertheless, it is on to point out that both embodiments can also be realized side by side and independently.

Overall, there are still some interesting areas for the blister pack 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 23 (before deep drawing) is about 150 μm to 600 μm, preferably about 400 μm, and at the kinks about 180 μm to 220 μm, preferably about 200 μm. 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 closure film 21 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 21, there 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 21 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 configuration of the lumpy product 22 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.

Particularly interesting parameter ranges for certain dimensions result in such a way that the lumpy product 22 has a fracture hardness of 50 to 120 N, in particular of at least about 60 N and / or that the lumpy Product 22 has a diameter of 5 to 10 mm, in particular of 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 31 and crease lines 6 to 10, preferably 8 surfaces, in the second wall portion 29 16 to 30, preferably 24 surfaces are exemplified in the illustrated embodiments in the first wall portion. 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 push-through packaging is particularly recommended for a lumpy product 22 which is merely one component of a multicomponent complete product, in particular of a cosmetic finished product. In particular, the lumpy product 22 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 colorant 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.

Finally, in another teaching, the use of the above-described packaging unit is claimed as packaging for cosmetic finished products, in particular hair colors, hair tints, care products or the like.

Particularly useful is the illustrated and described partial packaging in connection with the packaging unit according to the invention. Fig. 1 . 4 show such a packaging unit for a single- or multi-component end product, which consists of several separate sub-packages 1, 2, wherein on a first sub-package 1 with at least one product component one second sub-package 2 can be fixed with at least one further product component and the second sub-package 2 at least partially covers an opening 4 of the first sub-package 1 with its delivery side for the at least one further product component. It can be seen here the blister pack according to the present patent application as a dispenser 6 in the upper part of the second partial packaging. 2
