Description

PACKAGING SYSTEM

The invention relates to a packaging system for food with a starting from a container bottom of a container axis rotating and preferably about truncated cone sheath flared container jacket in the direction of a container opening surrounding an upper container edge extending container and a food containing chamber.

Such packaging systems are used, for example, for packaging liquid and / or pasty foods, esp. Dairy products. The food containing chamber is usually limited by the container shell and the container bottom.

In DT 25 34 748 A1 discloses a modular packaging system is given, in which in addition to the food containing chamber also inserted into the container opening and a cover sealable sealable lid is inserted. That in So described writing system contains so in addition to the food containing chamber also has a limited by the lid and the cover cavity, with the influence of the food received in the container to be prevented.

In a described in DE 76 22 067 U1 packaging system of the type mentioned in addition to the food containing chamber, a cavity in the bottom portion of the container is provided od for receiving a pack, such as a tea bag, a filling for coffee. Like. , is provided.

Similar packaging systems are described in DE 199 24 871 A1, wherein in the cavity in the bottom area according to this document, an aid, such as a spoon od. Like., May be arranged.

In a packaging system described in FR 2 701 924 A1 two chambers are provided, each of which may contain a food. The chambers are arranged one above the other and separated by an intermediate floor.

Similar packaging systems are described in DE 94 05 246 U1, wherein the packaging systems described in this document have two superposed cups and the bottom part of the upper cup is inserted into the upper edge region of the lower cup.

Other embodiments of packaging systems with two chambers each containing a food and arranged one above the other are described in EP 0 896 930 A1 and DE 82 26 733 U1.

Finally, a corresponding packaging system with two food compartments arranged one above the other, which are connected to one another via a jacket-like outer part, is specified in EP 1 876 106 B1.

Although storage and transport of food with the known packaging systems hardly cause problems, it has been found that the performance of appropriate packaging systems are inadequate in many cases. In view of these problems in the prior art, it is an object of the invention to provide a packaging system with improved performance characteristics.

According to the invention this object is achieved by a development of the known packaging systems, which is characterized essentially in that the food-containing chamber extending from the upper edge of the container in the direction of the container bottom, within the container shell and at least over part of the axial chamber height Having arranged at a radial distance from the container shell, the container axis encircling chamber jacket and a preferably arranged at an axial distance above the container bottom chamber bottom.

Thus, the packaging system according to the invention has a double-walled structure in which the food is separated from the environment on the one hand via the chamber casing and on the other hand via the container casing and a cavity is provided between chamber casing and container casing. It is thereby achieved that insulation between the food received in the chamber and the environment is provided via the cavity provided between the chamber jacket and the container shell, so that the packaging system can be removed after heating the food received therein, eg. In a microwave device without risk of injury ,

Damage to the packaging system according to the invention from the outside does not necessarily lead to leakage of the food received therein, because this is doubly protected, namely on the one hand by the chamber jacket and on the other hand by the container shell.

The cavity formed between chamber jacket and container jacket or chamber bottom and container bottom can be used for advertising or to improve the external appearance of the packaging system by bringing about special optical effects. In this cavity also aids and / or Kaufanreize, such as toys, can be accommodated. Overall, the performance characteristics of the packaging system according to the invention are thus significantly improved by the double-walled structure compared to the known packaging systems.

With regard to the possibly desired thermal insulation, the provision of the largest possible cavity for receiving additives or purchase incentives, the greatest possible variability in achieving desired optical properties u. Like., It has proved to be particularly useful if the radial distance between chamber jacket and container shell and / or the axial distance between the chamber bottom and container bottom at least in sections 5 mm or more, esp. 10 mm or more. In this case, the radial distance, starting from an upper support area of the chamber surrounding a chamber opening, in which the chamber is supported on an upper support area of the container surrounding the container opening, can increase in the direction of the chamber floor.

In the context of the invention, it has proved to be particularly useful when container and chamber are designed as separate components. These components can be materially and non-positively connected to each other in the context of the invention. However, it has proved to be particularly expedient if these separate components are positively connected to one another, because it is thus possible to disregard the use of food-grade hazardous adhesives and to achieve a particularly reliable and durable connection in comparison with a purely non-positive connection.

A particularly durable and production-technically easily realizable interlocking connection results when the upper support region of the container extending from the container jacket radially outwardly extending, preferably at least partially extending approximately perpendicular to the container axis Aufsetzbereich, in a direction towards the upper container edge extends extending, preferably frustoconical tapered holding portion, wherein the upper support portion of the chamber is designed to be approximately complementary to the upper support region of the container and clipped therein.

Thus, in this embodiment of the invention, the chamber bottom can be inserted through the container opening into the container, wherein the upper support region of the chamber after complete introduction of the chamber into the container in the upper Abstütz- Area of the container is clipped. In this case, a particularly durable positive connection is achieved when the axial height of the holding portion between 3 and 15 mm, preferably between 4 and 10 mm.

A connection between the chamber and the container can be achieved without risk of damaging the upper support region of the chamber and / or the container, if the holding region in an axial section plane an acute angle of 2 to 20 °, preferably 2.5 to 9 °, esp to 7 °, with the container axis encloses. At angles of less than 2 ° barely a positive connection is achieved. At angles of more than 20 ° required to obtain the positive connection deformation of the upper support region of the container is so large that the risk of damage.

Empirically it has been found that in particular when using containers and chambers in the form of polystyrene plastic cups, an optimization of the positive connection while ensuring the freedom from destruction during the preparation of the compound can be achieved if the ratio between holding angle and holding height in the range between 0.8 and 0.9 ° per millimeter, preferably 0.5 to 0.75 ° per millimeter.

A further stabilization of the connection can be achieved while simultaneously providing a sealing edge for a closure device of the packaging system according to the invention if the upper holding region of the container and / or the chamber changes into a flange region extending radially outward and approximately in a plane perpendicular to the container axis, wherein the flange portion of the chamber is preferably supported on the upper boundary surface of the flange portion of the container. In this case, a cover device designed to cover the chamber opening may be sealed onto the flange portion of the chamber. The cover device can, for example, be realized in the form of a conventional cover plate, in particular aluminum plate.

As already indicated above, it has proved to be particularly useful in the context of the invention, when the container and / or the chamber is designed as a plastic surface, with promotional promotional effects can be achieved if at least the container shell and / or the chamber jacket at least partially a transparent material is formed. If a packaging system according to the invention is to be used for accommodating promotional means in the cavity between the chamber and container, it has proved to be useful if in the container casing and / or the container bottom a removal device for removing a cavity formed in the cavity formed between the container and chamber Content is provided. This removal device may, for example, be realized in the form of a sealing foil forming the container bottom and optionally provided with a trigger tab, which closes the otherwise open container bottom. Additionally or alternatively, removal areas may be provided in the container casing and / or container bottom that are surrounded by one or more weakening lines.

As already mentioned above, it has proven to be particularly useful in the invention, when container and chamber are positively connected with each other, because in this way the food law regulations can be particularly easily satisfied while a reliable connection between the container and chamber is ensured without production problems. Container and chamber can be made of the same material.

In the context of the invention, however, it is also thought that container and chamber made of different materials, the chamber may be formed from a high quality, food law regulations sufficient material, while the container may consist of a simpler material.

As can be seen from the above explanation, the chamber of a packaging system according to the invention has a smaller axial height than the container.

In the following, the invention will be explained with reference to the drawing, to which reference is expressly made to all features essential to the invention, which are not further pointed out in the description.

In the drawing shows:

Figure 1 is a sectional view of a packaging system according to the invention in the assembled state and Figure 2 is a detail of the detail

C in the sectional view according to FIG. 1

The packaging system shown in the drawing has a total of 10 designated cup and a total of 50 designated chamber. The chamber 50 is accommodated coaxially with the container 10 in this.

The container 10 has a container bottom 12 and a container wall 14 extending therefrom in the direction of a container edge 30 extending around a container opening 40. The container wall 14 extends around a container axis and thereby widens in the direction of the upper container rim 30. In a middle section, the container wall 14 is designed approximately truncated cone-shaped or slightly curved dome-shaped. The container wall 14 goes over at its edge facing away from the container bottom 12 via a support region designated overall by 16 into a flange 22 extending approximately in a radial plane.

The chamber 15 accommodated in the container 10 comprises a chamber bottom 52, which merges into a chamber wall 54 extending in the direction of the upper container rim 30. The chamber wall 54 rotates the container axis coaxially with the container wall 14 and widens in the direction of the upper container edge 30. It is also designed approximately truncated cone-shaped, wherein the inclination angle to the container axis, however, is greater than in the container wall 14. The chamber wall 54 goes to her the bottom 52 facing away from a total of 56 support area designated in a sealing flange 62, which serves to seal a lid plate.

As can be seen particularly clearly from the illustration in FIG. 2, the support region 16 has a seating region 18 extending at its edge facing the container wall approximately in a radial cutting plane, which is frustoconical over a curve in a direction towards the upper container rim 30 tapered holding area passes. Between the holding portion 20 and the flange 22, an angle of about 85 ° is included, so that the holding portion 20 forms an angle of about 5 ° with the container axis. The upper support region 56 of the chamber 50 is designed to be complementary to the upper holding region 16 of the container 10 and clipped into it. It likewise comprises a contact region 58 extending from the upper edge of the chamber wall and which, at its edge facing the chamber wall, extends approximately in a plane. Dialen sectional plane extends and passes over a curve in a holding portion 60, which rests against the inner boundary surface of the holding portion 20. The holding region 60 merges at its upper edge into the sealing flange 62, which is arranged in a radial section plane. The Aufsetzbereiche 16 and 56 are, as shown in Figure 2, designed close together when chamber and container are inserted into each other. The individual components of the packaging system can be detached from each other in the nested position. They are designed as two independent, approximately cup-shaped components, in particular made of plastic. They may consist of polystyrene, polyethylene, polypropylene or the like. The height of the upper support portions 16 and 56 is about 10 mm in the embodiment shown in the drawing. Accordingly, the ratio between the bracket and the holding height in this embodiment is about 0.5 ° per millimeter.

In the embodiment shown in the drawing, the cavity formed between the container wall 14 and chamber wall 54 expands starting from the upper support region 16 and 56 towards the container bottom 12. Between the container bottom 12 and the chamber bottom 52 is a cavity with a height of more formed as 10 mm. The container 10 is designed overall as a transparent plastic cup, so that the cavity, optionally with the recorded in the chamber 50 food, through the container wall 14 can be seen.

The transparent container 10 may be provided with an optionally transparent shrink film at least over part of its height. On the chamber wall 54, a cladding coating may be applied. The chamber 50 can be made transparent overall. The chamber 50 may be made of a higher quality plastic than the container 10. The positive connection between the container 10 and chamber 50 may, if necessary, be stabilized by an adhesive.

Additionally or alternatively, the container and the chamber may be welded together in the area of their upper support areas 16 and 56, respectively, which may be done by heating the container and / or the chamber. For producing the packaging system shown in the drawing, the chamber bottom 52 is inserted through the container opening 14 into the container 10 until it is completely received therein, wherein the upper support portion 56 of the chamber 50 in the upper support portion 60 of the container 10 is clipped. Thereafter, the food may be filled in the chamber 50 and a sealing film be sealed onto the sealing flange 62. The lower boundary surface of the sealing flange 62 abuts against the upper boundary surface of the flange 22 of the container.

In the region of the container wall 14, a removal device optionally designed as a weakening line may be included for items received in the cavity formed between the chamber 10 and the container 15. The container bottom 12 may be designed as a releasable sealing film, so that in the cavity recorded objects can also be removed by a resulting after removal of the sealing foil bottom opening.

In the context of the invention, it is also conceived to make the container wall 14 translucent in color and also to make the chamber wall 54 translucent in color in order to achieve special optical effects that can be used for advertising purposes.
