Abstract

The combined can has a shell (2) of one material and a removable cover (3) of a different material. There is also a bottom made from either of these or of some other material, and foil (4) of yet another material fixed to the shell extending at least partly from the cover to the bottom. The foil, at least in certain regions, has a recess (42) in it. The cover has at least one projection (33) to engage in the recess. The recess may be in the form of a breach, separating one region (41) of the foil, covering an edge of the shell, from another region (43) fixed to the shell.

Description

The invention relates to a combination box with a fuselage a first material, at least partially in the Fuselage can be pushed in and removed from the same cover from a second material, a floor from a first, second or third material and one at least partially removable, attached to the fuselage, at least temporarily extending between the lid and the bottom Foil from a third or fourth material.

Such combination cans are for storing a variety of goods, such as candy, well known. However The known cans often come out fall off the lid from the fuselage, especially with strong ones Temperature fluctuations due to the different  thermal expansion of the lid and fuselage or more easy opening and reclosing of the combination box. Especially it is also undesirable if after falling out the lid also empties the contents of the can.

It is therefore the object of the invention, the generic To further develop the combination can in such a way that the above mentioned disadvantages of the prior art, i. H., that in particular a tight fit of the lid in the Fuselage is ensured. The manufacturing should cost for a combination can according to the invention for one essentially do not exceed the known combination box.

For a combination box of the type mentioned at the beginning The object of the invention essentially achieved that in the film, at least in some areas, a recess is introduced, and the lid at least one projection for engaging in the recess.

The invention is therefore the surprising finding based on the fact that by intervening or by snapping the Protrusion of the lid into the recess in the film the fuselage is securely held. Even if namely, the lid shrinks relative to that Hull comes, for example when cooling to temperatures below 0 ° C when using a plastic lid and a hull comprising metal and / or paper the protrusion is still attached to the foil on the fuselage to grab.

This is a further development according to the invention  characterized in that the recess in the form of an undersize Chung is formed, the first film area, the for at least partially covering a fuselage edge attached to the fuselage by a second foil leg rich, which is attached to the hull, over the fuselage opening extends and, preferably completely, is removable. During the second film area, the Keeping the contents of the can fresh is preferred by the customer is completely removable, the first film remains area on the fuselage to ensure that even after the first time the customer opens the combination box Snap the protrusion under the first film area is ensured. The constant sales also protects formation of the fuselage edge, which mostly comes from a cutting process from damage and injuries.

The invention beats for manufacturing reasons before that the foil is sealed to the fuselage and along a predetermined breaking point to form the recess separately is. This enables conventional seals to be used process for cling film, which the manufacturing co keeps low.

It is further preferred that the first film area Fully encompasses the fuselage rim.

To facilitate the handling of the invention Combination box, the invention proposes that the recess essentially parallel to the fuselage edge and preferably runs over the corresponding inner circumference of the fuselage.  

Furthermore, the invention proposes that several projections are provided, or one around a complete exterior provided starting protrusion of the lid is.

It can also be provided according to the invention that the Projection in the form of a form-fitting nose in a rim richly formed of the lid, the outer circumference the inner circumference of the fuselage including foil, preferably paßge precisely at room temperature.

In one embodiment of the invention, the Cover a support area substantially perpendicular to the Edge area for at least partially reaching around the Have the edges of the fuselage, which is a deep impression of the Lid in the fuselage prevented.

For reasons of stability, the invention also proposes before that essentially parallel to the support area Cover area for reaching over the fuselage opening runs, preferably the covering area with one end and the support area with the other end of the edge is connected.

It is further preferred that the lid one with the edge has richly connected gripping area, which is preferred wise in the opposite direction to the support area extends parallel to the cover area. By grasping the The lid can easily be removed from the fuselage area pull out.  

Furthermore, the invention proposes that the first material Paper and / or metal comprises the second material Plastic, preferably polypropylene or polyethylene, comprises that the third material is metal, preferably white sheet, comprises, and / or that the fourth material a Me tall membrane, preferably an aluminum membrane.

The combination can according to the invention thus has the following parts:
The lid pull-off force is increased by the engagement of the projection of the lid in the recess in the film on the fuselage.

Even if the second film area is removed, the projection can increase the first film area reach under the lid pull-off force.

The secure adherence of the first film area to Fuselage rim, even after removing the second foil area to allow access to the can halt, also protects against damage and injury tongues.

Shrink effects of the lid relative to the fuselage major temperature fluctuations due to different Licher thermal expansions of the corresponding Combination can materials are compensated for by the fact that the first film area has a finite thickness, which is about attacking the ledge on the fuselage ensures the first film area.  

Further features and advantages of the invention result from the description below, in which an exec Example of the invention based on a schematic Drawing a part with just a single figure cross section through a combination can according to the invention, is explained in detail.

As the figure shows, 1 comprises a erfindungsge Permitted Kombidose a body 2, a cover 3 and a film 4 which BEFE via an adhesive layer 5 on the hull 2 is Stigt.

The fuselage 2 , which is cut out, for example, from a wound cylinder from a metal-coated paper strip, has an upper cutting edge 21 . The film 4 , which is a conventional aluminum membrane suitable for sealing, is sealed to the fuselage 2 according to the state of the art and separates ge along a predetermined breaking point into a first film area 41 , an interruption 42 and a second film area 43 . The first film region 41 encompasses the cut edge 21 of the fuselage 2 in the form of a ring region. The second film area 43 , on the other hand, forms the film area that is completely removed to allow access to the contents of the combination can 1 . For this purpose, the removable area 43 can be equipped with a known rapid or the like.

The lid 3 is preferably made of plastic such that it has a support area 31 for gripping over the cutting edge 21 , an edge area 32 perpendicular to the support area 31 with a positive locking nose 33 and a gripping area 34 at one end of the edge area 32 and a cover area crossing the fuselage opening 35 at the other end of the edge area 32 .

In the body 2 covered with the film 4 , the elastic cover 3 can be pressed in such a way that the positive locking nose 33 engages in the interruption 42 , as shown in the figure. This ensures a firm hold of the Dec kels 3 in the fuselage 2nd

The elastic cover 3 can easily be pulled out of the fuselage 2 by reaching under the gripping area 34 .

The removable region 43 of the film 4 can be completely detached from the fuselage 2 , but without there being a deterioration in the fit of the cover 3 in the fuselage 2 , since the form-fitting nose 33 is still under the ring region 41 for reaching under the ring region 41 one can snap.

The in the above description, in the drawing as well as features of the invention disclosed in the claims can be used individually or in any combination for the realization of the invention in its various NEN embodiments may be essential.
