BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATION

This application is a national phase of PCT/DE/89/00558 filed Aug. 25, 1989 and based, in turn, upon German national application P 3829 778.7 filed Sep. 2, 1988 under the International Convention.
1. Field of the Invention
The invention relates to a package for small parts, consisting of a cup-shaped bottom and a cup-shaped lid, whereby the bottom and the lid facing each other with their open portions can be slipped onto each other and the lateral walls of the lid overlap with those of the bottom part, as well as of an adhesive label which is glued to the lid.
2. Background of the Invention
Two-part packages for self-service are widely known in the art. For instance, reference can be made to U.S. Pat. No. 4,619,364. It is also customary for the self-service package to have adhesive signs or the like on the lid surface, containing information about the goods and/or price of the corresponding goods.
As a rule, an adhesive label is affixed to cover the frontal surface and the lateral surfaces, as well as the back wall of the package, so that its tamper-proof function is fulfilled, since the package can be opened only by destroying or tearing the label. However, affixing such safety labels is relatively difficult, since the placing of the label can be done only when the package is lifted from its support, in order to place the label on its back wall.


OBJECTS OF THE INVENTION

It is therefore, a principle object of the present invention to provide a package or box for self-service of the generic kind having an adhesive label or the like serving as tamper-proof closure of the package and affixed to the package while it is resting on a support.


SUMMARY OF THE INVENTION

According to the invention at least one wall of the box, particularly a lateral wall of a lid portion, is provided with an opening. The adhesive label can be affixed to the wall, particularly the lateral wall and, covers the opening while reaching parts of the bottom wall located underneath this opening in the closed position of the package.
Solutions to this problem are known to the state of the art, wherein an adhesive label is affixed to cover the frontal surface and the lateral surfaces, as well as the back wall of the package, so that its tamper-proof function is fulfilled, since the package can be opened only by destroying, respectively tearing the label, however affixing such safety labels is relatively difficult, since the placing of the label can be done only when the package is lifted from its support, in order to place the label also on its back wall.
The structure according to the invention enables affixing the adhesive label to a package resting on a support, without lifting the package from its support. For instance, in order to fill the package the cup-shaped bottom part is transported on a conveyor belt or the like and directed towards certain filling stations. In the following step the lid portion is fitted over the bottom and after that the adhesive label is affixed over the area provided with the window-like opening. The lid can be affixed to the bottom portion by means of articulated joints or can be an independent part. When the lid thickness is relatively small, the adhesive layer of the lid portion reaches the outside wall surface of the cup-shaped bottom portion located underneath the window-like opening, so that the adhesive label is glued to the outside of the lid wall and to the outside of the bottom wall as well. The opening of the package is possible only when the adhesive label is removed or destroyed. In the case of two-part packages it is possible and often necessary to provide several openings at several spots of the lid, each being covered by a respective adhesive label or all of them covered by one continuous label.
A particularly advantageous embodiment of present invention has the wall, particularly the lateral wall of the bottom part with a surface projecting towards the respective confronting wall of the covering lid portion. The projection can be fitted into the op
