Description

The invention relates to a container comprising a packaging and a product accommodated in the packaging, wherein the packaging comprises a paper material and the product comprises at least two substantially dimensionally stable, cuboid-shaped bodies.

Such containers are known, for example, as blister packs, which contain a cleaning agent suitable for use in a dishwasher, washing machine, or toilet cistern. The blister pack typically comprises a blister cover made of a plastic material that holds the product, as well as a blister card made of cardboard and sealed with the blister cover.

Such packaging has the disadvantage that it is made of different materials, requiring users to first disassemble the empty packaging into its various materials before disposing of it in the respective recycling streams. Given the increasing awareness of sustainability and environmental protection, the high plastic content is considered a particular disadvantage. Furthermore, opening such packaging is often difficult for users, as the seal between the blister card and the blister cover is often difficult to separate cleanly and easily.

There are also known packagings that are essentially made of a paper-based material and can be opened using a tear strip. The tear strip is usually made of a plastic material and must therefore be disposed of separately.

The present invention has set itself the object of providing a container comprising a packaging and a product contained in the packaging, which is characterized by particularly sustainable packaging and which, at the same time, is particularly easy to open.

This object is achieved by an object according to patent claim 1. Concrete embodiments and further developments of the invention are the subject of the dependent claims.

According to patent claim 1, the invention relates to a container comprising a packaging and a product accommodated in the packaging, wherein the packaging comprises a paper material and the product comprises at least two substantially dimensionally stable, cuboid-shaped bodies. The container according to the invention is characterized in that the packaging comprises a blister card and a cuboid-shaped blister hood arranged on the blister card, wherein both the blister card and the blister hood are made of the paper material and wherein the at least two bodies essentially completely fill the blister hood, wherein the packaging furthermore has a material weakening acting as a crease line, which extends over both the blister hood and the blister card and which runs in a plane lying between the at least two cuboid-shaped bodies, such that the packaging can be broken open by bending the container along the crease line, so that the product can be removed from the packaging, wherein the product accommodated in the packaging acts as a lever when opening the packaging.

In other words, the invention provides a container in which at least two cuboid bodies are arranged in a blister hood made of a paper material and essentially completely fill the latter, wherein the blister hood is closed by means of a blister card also made of a paper material and wherein a material weakening serving as a crease line is provided, which extends over both the blister hood and the blister card. The material weakening runs in a plane between the at least two bodies, so that the packaging can be broken open by bending the container along the crease line. The bodies, which are positively received in the blister hood, act as a lever, which facilitates the breaking open of the packaging. The individual bodies can be removed from the packaging after it has been broken open. It is therefore an advantage of the container according to the invention that additional opening aids such as tear strips or the like, which are often made of a plastic material and must be disposed of separately, can be dispensed with. Rather, the packaging can be made essentially entirely from a paper-based material and can therefore be recycled as a whole.

The breaking open of the packaging of the container according to the invention along the crease line is particularly facilitated and supported by the fact that the essentially dimensionally stable product contained in the blister hood essentially completely fills the blister hood. In this way, a bending moment applied during the bending process can be very efficiently transferred via the essentially dimensionally stable product to the packaging, which then automatically breaks along the crease line acting as a predetermined breaking point. breaks open. Because the blister cap is essentially completely filled with the product, any other indentation or deformation of the blister cap during the opening process can be prevented; rather, the applied bending moment is essentially fully effective when the predetermined breaking point is opened.

According to one embodiment of the invention, the product comprises four identical cuboid-shaped bodies, with the material weakening running in a plane located between each two bodies. In other words, more than two, for example four, bodies can be accommodated in the packaging. The individual bodies can be designed as identical cubes. The material weakening runs in a plane located between each two bodies. By breaking open the packaging along the crease line, the blister cover is divided into two halves, so that two bodies can be removed from each of the two halves.

The product may, for example, be a cleaning agent. In particular, it may be a cleaning agent for introduction into the cistern of a toilet. The product may be highly hygroscopic and water-soluble. As a cleaning agent, it may, in particular, contain surfactants.

According to the invention, the product is essentially dimensionally stable. For the purposes of the invention, dimensionally stable means that the product does not give significantly under pressure. This is a prerequisite for the product to optimally support the opening process by acting as a rigid lever, through which an applied bending moment is transferred essentially completely to the packaging to be opened. If the product were too flexible, a significant portion of the applied bending moment would be used to deform the product. At the same time, the characteristic of dimensionally stable means that the product can be flexible to a certain extent and, for example, can be depressed to a very small extent by applying pressure to it at specific points with a finger.

A further embodiment of the invention provides that the bodies are each individually wrapped in a water-soluble film. Such a film acts as a barrier against fragrances and/or dyes contained in the product. By wrapping the individual bodies in a film, it is possible to prevent a perfumed product from losing its fragrance before its actual use, for example during storage, or from undesirably perfuming the environment. Furthermore, such a film also serves to protect the hands and/or clothing of a user when removing the product from the packaging, as the products are often intensely colored and can therefore stain skin and/or clothing. The packaging itself is also protected from staining in this way. For example, it can be a film based on polyvinyl alcohol (PVA), which dissolves in water and then releases the cleaning agent.

Additionally or alternatively, a separating element can also be provided, which is arranged between the bodies within the blister cover. For example, a separating element formed from two intersecting paper or cardboard strips can be provided, which can be used to separate four bodies from each other in the packaging. This has the advantage that the individual bodies do not come into contact with each other during storage of the container and thus cannot rub against or stick together.

The material weakening can be implemented in different ways. In principle, it can be designed as a perforation, for example, which makes it particularly easy to break open the packaging. However, with a material weakening designed as a perforation there is a risk that moisture from the environment will penetrate the packaging. This is particularly disadvantageous when using a highly hygroscopic product, as it can be affected by the absorption of moisture while still in the packaging. For this reason, the material weakening can also be designed wholly or partially as a score and/or creasing. A score is understood to be processing the packaging material with the aid of a cutting tool, whereby the material is cut to a defined depth, but the cut does not completely penetrate the material. In this way, the material is weakened in the area of the score and is therefore easily bendable and ultimately breakable, but before the opening process it is essentially impermeable to moisture and other environmental influences such as dust and water vapor. Creasing, on the other hand, is a processing of the packaging material in which the material is merely deformed or compressed using a suitable pressing tool, but not cut. Creasing also makes the material easier to bend in the creasing area. At the same time, it provides high resistance to environmental influences such as moisture.

According to the invention, it can be provided that the strip extending over the blister hood Part of the material weakening is formed as a score. In other words, at least that part of the material weakening which extends over the blister hood can be formed as a score. In this way, the blister hood is particularly easy to break open during the opening process of the packaging. In order to simultaneously ensure the highest possible resistance to moisture and other environmental influences, the score can be formed on the inside of the blister hood facing the product, so that the outside of the blister hood remains intact. Alternatively, the score can also be formed on the outside of the blister hood facing away from the product. Finally, it is also possible for the score to be formed on both the inside and outside of the blister hood. In this case, the score on the inside and the outside can lie directly on top of one another, with the score depth in this case being adjusted so that a sufficient proportion of undamaged paper material remains between the two scores. Alternatively, the inner and outer scorings can also be offset from each other by a small distance. For example, they can be offset from each other by up to approximately 10 mm.

According to a further embodiment, the portion of the material weakening extending over the blister card is designed as a crease. The crease can extend substantially over the entire length of the blister card. The blister hood and blister card are generally connected to one another in a manner known per se such that the blister hood is completely closed by the blister card. The dimensions of the blister card can extend beyond the blister hood. According to the invention, the material weakening extending over both the blister card and the blister hood lies in its entirety in a plane between the at least two cuboid bodies. The portion of the material weakening extending over the blister hood can run at least partially parallel and aligned with the portion of the material weakening extending over the blister card.

In principle, the part of the material weakening extending over the blister card can also be designed as a scratch, at least in sections.

According to one proposal of the invention, the blister hood can be formed by folding a material blank. For this purpose, a corresponding material blank made of a paper material is provided, from which the blister hood can be formed by folding. The material blank can, in particular, comprise connecting tabs with the aid of which the folded blister hood can be connected to the blister card. In the provided material blank, the material weakening serving for later breaking open the packaging is advantageously already formed, for example in the form of a scoring line as described above. In addition, the material blank can comprise further folding lines, for example in the form of scores, which merely facilitate the folding of the blister hood.

For the purposes of the present invention, a paper material is understood to mean a paper-based material. This can, for example, be a cardboard material of a certain thickness.

Particularly when using a highly hygroscopic product, the blister cover and blister card can be bonded together in a moisture-proof manner. For example, the blister cover and blister card can be glued or sealed together, for example, in the area of the connecting tabs, in such a way that essentially no moisture can penetrate the packaging through the adhesive or sealing areas.

1 shows a container designated as a whole by 1, which comprises a packaging 2 and a 1 not visible product 3 contained in the packaging 2. The product 3 is a water Soluble and surfactant-containing cleaning agent which can be added to the cistern of a toilet. Product 3 contains 1 illustrated embodiment, two essentially dimensionally stable, cube-shaped bodies 4.

The packaging 2 comprises a blister card 5 and a cuboid blister cover 6 arranged on the blister card 5. Both the blister card 5 and the blister cover 6 are made of a cardboard material.

The two in the 1 The cube-shaped bodies 4, which cannot be seen, are accommodated in the blister cap 6 and essentially fill it completely.

The packaging 2 further comprises a material weakening 8 acting as a crease line 7, which extends across both the blister card 5 and the blister hood 6. The material weakening 8 runs in a plane that lies between the two cube-shaped bodies 4 and orthogonal to the blister card 5. By bending the container 1 along the crease line 7, the blister hood 6 can be broken open along the material weakening 8, so that the product 3 can be removed from the packaging 2. 9 , which will be discussed in more detail later, shows another embodiment of a container 1 which has been bent along the fold line 7 and in which the blister cover 6 has been broken open. The product 3 can be removed from the packaging 2 in this state.

The product 3 contained in the packaging 2 acts as a lever when the packaging 2 is opened, such that a bending moment applied during the bending process is very efficiently transferred via the essentially dimensionally stable product 3 to the blister cap 6, which then breaks open along the material weakening 8 acting as a predetermined breaking point. For this purpose, the product 3 essentially completely fills the blister cap 6, so that the applied bending moment is essentially completely effective when the predetermined breaking point is severed and does not otherwise deform or compress the blister cap 6.

The portion of the material weakening 8 extending over the blister cap 6 is formed as a scoring 11. In the 1 In the illustrated embodiment, the scoring 11 is formed on the outer side 15 of the blister hood 6. Alternatively, the scoring 11 can also be formed on the inner side 12 of the blister hood 6 facing the product 3; in this case, the outer side 15 of the blister hood 6 is intact and there is particularly good protection against environmental influences such as moisture. Finally, as already described above, the scoring can also be formed on both the inner and outer sides. In any case, the scoring 11 causes the blister hood 6 to break open slightly along the scoring 11 when the packaging 2 is bent along the folding line 7.

The portion of the material weakening 8 extending over the blister card 5 is in contrast formed as a creasing 13. The creasing 13 extends over the entire length of the blister card 5, which is evident from the rear view of the 2 is better visible. It therefore also runs below the blister hood 6 and is aligned with the portion of the material weakening 8 extending over the blister hood 6. The entirety of the material weakening 8, comprising the scoring 11 extending over the blister hood 6 and the creasing 13 extending over the blister hood 5, lies in a plane which lies between the two cube-shaped bodies 4 and orthogonal to the blister card 5. The creasing 13 essentially has a supporting effect during the opening process of the packaging 2 by making it easier to bend the packaging 2 along the folding line 7. The scoring 11, on the other hand, along which the cardboard material of the blister hood 6 is weakened to a greater extent than the cardboard material of the blister card 5 along the scoring 13, acts as a predetermined breaking point along which the blister hood 6 breaks open when a corresponding bending moment is applied.

The blister cover 6 and the blister card 5 are glued together in such a way that essentially no moisture can penetrate into the packaging 2 via the adhesive areas. For this purpose, the blister cover 6 comprises connecting tabs 16, via which an adhesive connection is established between the blister cover 6 and the blister card 5.

3 shows a material blank 14 made of a cardboard material from which a blister hood 6 can be formed by folding. 3 shows a view of the later inner side 12 of the blister hood 6. In the exemplary embodiment shown here, the scoring 11 is formed on the inner side 12 of the blister hood 6. In addition, the material blank 14 comprises a plurality of fold lines 18 formed as grooves, along which the material blank 14 can be folded particularly easily to form the blister hood 6. Connecting tabs 16 are formed on the edges of the material blank 14, which, as already described above, serve to connect the blister hood 6 to the blister card 5. In addition, the material blank 14 comprises connecting tabs 17, which serve to connect the side walls of the blister hood 6 to one another, for example by gluing or sealing them.

In the 4 A separating element 10 is shown, which is made of a cardboard material and can be arranged within the blister hood 6 to separate the two cube-shaped bodies 4. The separating element 10 comprises two webs 19, 20 arranged orthogonally to one another, wherein the bodies 4 accommodated in the packaging 2 are separated from one another by the cardboard web 19. This can prevent the two bodies 4 from coming into contact with one another during storage of the container and from rubbing against or sticking together. The separating element 10 can also consist solely of the web 19, which can be inserted between the two bodies 4.

In the 5 to 9 A further embodiment of a container 1 according to the invention is shown. It differs from the one shown in the 1 to 4 The embodiment shown differs only in that four identical cube-shaped bodies 4 are accommodated in the packaging 2 and the blister cover 6 is correspondingly larger. The blister cover 6 can be made of the material shown in the 7 shown material blank 14 by folding in the manner described above in connection with 3 The material weakening 8 is designed in such a way that two bodies 4 are arranged on each side of the material weakening 8. The four bodies 4 can be separated within the blister hood 6 by a separating element 10, as shown in the 8 shown, are separated from each other. The separating element 10 comprises two intersecting webs 19, 20, which are arranged on a base 21. This creates four separate compartments, each of which can accommodate a body 4. The separating element 10 can also comprise only the two intersecting webs 19, 20, which are inserted between the four bodies 4.

9 shows an opened container 1, which was previously folded along the fold line 7. It can be seen that the blister card 5 is only folded along the material weakening 8 formed as a groove 13, while the blister hood 6 is broken open along the material weakening 8 formed as a score 11 and thus functioning as a predetermined breaking point. In this way, the product 3 contained in the blister hood 6 is immediately accessible. It is 9 It can be seen that two cube-shaped bodies 4 are arranged on either side of the material weakening 8. Each individual body 4 is wrapped in a water-soluble film based on polyvinyl alcohol, which is indicated by the hatching. In addition, a cross-shaped separating element 10, as shown in the 8 shown, be inserted between the four bodies 4. This is for reasons of clarity in the representation of the 9 not shown.
