for a patent on a hinged packaging container

The invention relates to a packaging container that has a packaging cavity which is enclosed on all sides and which can be opened by opening the packaging container becomes accessible for the purpose of filling with goods and after filling the packaging container or after removal of the goods from the same by folding can be closed again.

The packaging container allows the packaging to be opened and reclosed as often as required.

Packaging container-forming hollow body made of two parts, an upper molded part and a flat lower part, is composed. The upper part of the mold is designed like a hood and has in the area of its opening on its walls an outwardly curved circumferential flange edge; the upper part of the mold is foldable. The molded hollow body - and thus the packaging container - is formed by the Hood-like shaped upper part with its flange attached to the surface of the lower part in such a way that both together enclose the packaging cavity.

Packagings that plan by joining a hood-like molded part with a flange edge and a Bottom part are formed, are known under the name of blister, bell or hood packaging. Of the The hood-like part of the packaging usually consists of plastic and the flat bottom part in general made of cardboard which has a sealable layer of polymeric material on one surface.

To remove the product from the known packaging of the type mentioned, the hood of the Bottom part by destroying the sealing edge connection

In another known packaging of this type, this can be opened by making a perforation in the Separates the bottom part and thereby removes a portion of the bottom part. Again, this packaging is after it was opened and cannot be closed again.

Resealable hood packaging is also known, which makes the hood and base part light can be separated from one another and reassembled again that the bottom part is designed as a slide. In this known form of packaging, however, must two or three side surfaces of the hood be folded so that they form rails to the slide lead and hold. The disadvantage of this packaging is that it has less mechanical stability has, the larger it is designed or the heavier the product contained in it is.

In the case of the known packaging, in order to be able to close the packaging filled with filling goods,

That point of the hood-like upper part where the opening and upper edge of a partial side wall meet is to be referred to as the pivot point. According to the invention, two partial side walls running in the same plane have a common pivot point, this common point is referred to as the hinge point. The upper part accordingly has two hinge points. The two hinge points of the upper part are arranged in such a way that their straight connecting line is the shortest possible. This connecting line should be referred to as the fold line.

In this case, the opening edge ends above the level of the flange edge. This end the opening edge is referred to as the opening edge end point.

In particular, thermoplastic plastic films made of polystyrene, polyolefins, but very particularly made of FVC film suitable. In particular, however, a clear, tough PVC-based film is used to manufacture the upper part suitable. Tough film is to be understood as meaning one that has at least the toughness of a film Based on emulsions PVC.

The sections forming the lower part are on the underside attached to the flange edge of the upper part. In this arrangement they close the receiving cavity of the top.
