Definitions

• the invention relates to a packaging unit for a single or multi-component end product according to the preamble of claim 1, a partial packaging of this packaging unit according to the preamble of claim 36, a method for producing a multi-component end product according to the preamble of claim 56 and a use thereof Packaging unit according to the preamble of claim 59.
• Multi-component end products are known from the cosmetics sector, from the adhesive sector or from the painting sector (DE 102 08 874, DE 102 08 875). It is often the case here that the individual components may only be brought into contact shortly before use in order to avoid undesired chemical reactions.
• the packaging unit then has three main functions: First, the packaging unit ensures separate transport and storage options for the individual product components.
• the packaging unit is also optically designed in such a way that it conveys an appealing and thus sales-promoting impression in the sales room.
• the packaging unit generally also provides a way of bringing the product components into contact with one another in a predetermined manner before use. This process is called activation below.
• Packaging units for the above-mentioned multi-component end products therefore usually consist of several separate partial packs.
• a second partial packaging with at least one further product component can be defined on a first partial packaging with at least one product component.
• the known packaging unit for a two-component product, from which the invention is based has a bottle-shaped first partial packaging for receiving a first product component and a second partial packaging in the form of a crowner for receiving a second product component.
• the Crowner is implemented here as a cardboard sleeve that is already attached to the opening of the bottle-shaped first partial packaging when ready for sale.
• An ampoule containing the second product component is provided on the second partial packaging, which is detached from the second partial packaging before use and the contents of which are placed in the opening of the first partial packaging (activation).
• the known packaging unit does not offer a satisfactory solution, particularly in the case of multi-component end products in which individual product components may not be touched. Basically, there is a risk that the user will come into contact with at least the second product component when opening the ampoule or when filling. In addition, the above-mentioned packaging unit cannot completely avoid “pouring past" the second product component.
• a container system consisting of two bottles, one bottle being closed with a membrane or a valve and the other bottle having a pin in the form of a tip for piercing the membrane or for opening the valve ,
• the two separate bottles are connected to each other and then a product is formed by manually deforming the bottle transferred another product to the other bottle.
• the disadvantage is that the two bottles are available separately when ready for sale and are only connected to one another when they are used. Part of the container system may be lost during storage and transportation.
• two-component packaging is known, for example from the applicant's document DE 25 39 291 A1, which consists of a one-piece mixing container holding the main component and a head container holding the additional component, a detachable application tip molded onto the bottom of the mixing container and one the piercing of the bottom of the head container, which is designed as a separating film, and which extends into the vicinity of the bottom.
• a packaging has the disadvantage that in the ready-to-use state, no need-based quantity metering can be carried out because the mixing container and the head container are permanently connected to one another.
• This packaging is only suitable for the storage of two-component products and does not permit use for a single component.
• the activation of a multi-component end product is also subject to time requirements and waiting times, which can 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 the activation is continued by adding further product components. If these response times are not met, activation may even fail depending on the application.
• Such waiting times cannot be influenced with the known packaging unit. It is possible for the user, for example, 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 specified here. Waiting times of 0.2 to 30 seconds are common here.
• the known packaging units offer the user a complex and uncertain way of activating the multi-component end product with only a low reproducibility of the activation process.
• the packaging described in the prior art is intended for two-component products to be produced before use, but they are not suitable as packaging for the separate storage of components, at least one of which could also be used without the other component. An individual dosage by the user is impossible.
• the present invention is based on the problem of designing and developing the known packaging units in such a way that, in the ready-to-use state, a single-component end product or a multi-component end product can be produced by activation by the user in a simple manner, determined in time and reproducibly and without risk to is possible for the user.

It is further provided according to the invention that in the ready-to-use state, dosing of the product from the first partial packaging is also possible if the second partial packaging is arranged on the first partial packaging.
• This provides the user with a multitude of possibilities for using the packaging unit according to the invention, such as, for example, single-component dosing from the first or second part packaging, multi-component dosing from the second part packaging or, depending on requirements, dosing of the components from the second part packaging into the first part packaging.

• the user When the multi-component end product is activated, the user is thus forced to bring the second partial packaging into the predetermined position on the first partial packaging. This makes the activation process reproducible and safe for the user. Contact of the user with the second product component can be avoided in any case.
• the second partial packaging at least partially covers the opening of the first partial packaging when ready for use. This means that further product components in the ready-to-use state cannot be passed through the opening of the first partial packaging as long as the second partial packaging is fixed to the first partial packaging.

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, so that a certain behavior of the side wall 27 when pressure is exerted on the bottom area 26 in the axial direction. In addition, this contouring of the upper part 23 allows some interesting visual and design effects to be achieved.
• stiffeners 31 are arranged overall in the manner of a honeycomb structure or, as here, in the manner of a brilliant cut structure.
• the plastic material of the upper part 23 offers particularly interesting design-related aspects.
• FIGS. 6 and 7 show, moreover, that the base region 26 is flat and merges into the first wall section 28 via a kink line 32.
• stiffeners 31 also makes it possible to implement axially extending buckling lines, as shown here.
• the distribution of the stiffeners 31 over the two wall sections 28, 29 creates the optimal possibility of influencing the behavior of the upper part 23 when pressure is exerted on the base region 26.
• the bottom region 26 merges into the first wall section 28, in particular with the first wall section 28 is jointly dome-shaped. This is not shown here, however.
• FIGS. 7 and 8 also show that here the second wall section 29 merges directly into the closure flange 2, forming a kink line 33.
• FIG. 9 shows, in an enlarged detail, the relationships in the area of the kink line 34 between the side wall 27 and the ring flange 35.
• the arrow indicates how the area of the kink line 34 exerts axial pressure on the bottom area 26 of the upper part 23 downwards and outwards.
• the connecting arch between the ring flange 35 and the jacket section 36 has the function of a pivot hinge.
• the arrow makes it clear that the passage opening effective for the product 22 at the level of the kink line 34 tends to increase radially due to the axial pressure on the base region 26. Of course, this also depends on the elasticity of the plastic material used. In any case, the direction of the force action is clear. It can be clearly seen that, according to the preferred teaching, the transition from the ring flange 35 to the jacket section 36 is rounded, that is, it does not form a kink line. This promotes the controlled hinge function of this area.
• this is an approximately cylindrical jacket section 36.
• This cylindrical jacket section 36 allows the push-through packaging to be inserted overall into a circular opening in a holder made of cardboard, for example.
• This can 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 jacket section 36, which widens slightly towards the opening 20, is readily realized. A precisely cylindrical course is also expedient and producible.
• the construction is also of interest if, as shown in FIGS. 8 and 9, the jacket section 36 extends slightly widening from the opening 20 to the ring flange 35, which enables a kind of locking in an opening in a cardboard strip.
• the overall height of the upper part 23 of the blister pack should be 8 to 15 mm.
• FIG. 9 shows an exemplary embodiment of a push-through packaging in which the features of the exemplary embodiment of FIG. 6 are also implemented, that is to say the teachings of the two independent claims are combined with one another.
