DE6933098U - LID PACKING - Google Patents

Description

In the case of a large number of lightweight packs made of deep-drawn foils or molded or injection-molded plastics, it is customary to produce the pack from a larger lower part that largely encompasses the packaged goods and a smaller or even flat cover. This is particularly important when the goods to be packaged must have access to air in the box. While it is generally not particularly difficult to secure the lid to one side of the pack so that it can be opened and closed, particularly in deep-drawn manufacture by machining a corresponding kink line in the tool, it is sometimes not very easy to hold the lid on the opposite side. gfc έ \ ζ | ff% $ \ | Ί | Ο

In the case of a relatively thick material, a lock can be achieved here by means of known button-like constructions A closure is possible by attaching crochets or slits. Jc easier the plastics used will be, In particular, the thinner the deep-drawn foils, the more difficult this closure, which is then ultimately in the

in most cases simply by putting on a self-adhesive strip must be done. On the other hand, this is not a sensible solution, since in many cases the pack is opened several times and should be closed.

The innovation according to the invention is intended to provide a remedy here. According to the innovation is attached to a lid pack, in particular made of deep-drawn foils, but also made of injection-molded or pressed plastics, made a lid on one side, made hinged using an embossed, drawn or cast groove and on the other side, using a slight extension, right-angled, acute-angled, poly-angled or bent back upwards.

At the corresponding counterpart of the lower part, the material is also extended and this is done accordingly round, several times angled or semicircular bent so that a last narrow strip is very hard kinked and at the Closure pulls over the raised edge of the lid and so a safe and yet with light pressure over the entire surface represents fast-release type of closure. Some exemplary embodiments are shown in the figures.

Figure 1 shows, for example, the design of such a lid pack, in which the type of embodiment plays no role in the context of the innovation. It is essential that the cover D, using a drawn or pressed groove D 1, is connected to the lower part U on one side. On the opposite side, the cover is bent back upwards in the form of a smaller extension at D 1. The lower part is also lengthened at U 1 and also bent backwards in accordance with the necessary lock.

Here, the bend of the cover D 1 is designed largely round, while the corresponding bends of the lower part at U 1 are largely adapted to curves. FIG. 3 shows an example of a similar embodiment in which largely angled edges are provided, this applies to the bending of the cover at D 1 and to the bending of the lower part at U 1, which is bent here in several sections. Finally, FIG. 4 shows a further embodiment in which the cover bend at D 1 is distributed over several angles. For this purpose, the lower part design according to FIG. 2 or FIG. 3 is then possible. These exemplary representations in FIGS. 2, 3 and 4 are only intended to indicate the possibilities. Further variants are definitely possible in this area. PROTECTION APPROACH 1.) Lid pack made of plastics of various types, in particular but deep-drawn foils, consisting of a lower part and an upper part, with both parts flap-shaped on one edge are interconnected, characterized in that at the opposite support point of the upper part on the lower part, the upper part is slightly extended and bent upwards and backwards and that the lower part is also bent or kinked backwards in a larger shape at the corresponding edge. 3309-8 -4- B »» »J 5 IJ 7 1
