DESCRIPTION:

BRIEF SUMMARY
The invention relates to an anti-theft box for displaying goods that are attractive by theft in shops and department stores, comprising a cassette having a lid which can be locked in closed position and can be unlocked only by means of a special tool, and an element on or in the anti-theft box for wireless activation of an alarm device if the anti-theft box is carried through the exit of the shop or the department store. The term "exit" then includes also the exit from a defined sales region in a department store or shop center.
Anti-theft boxes of this kind are used for displaying i.a. jewellery, watches and other small and expensive products and for displaying video-cassettes and video-games.
Specific demands are placed on an anti-theft box of the kind referred to above in order that such anti-theft boxes shall be used by the retail trade: portions because the display of the goods as a consequence thereof can be considerably more difficult since the anti-theft boxes in that case cannot be displayed in the shop on existing shelves or in existing racks without considerably enlarged space being required; that the owner of the shop has not to bear too large costs in order to prevent theft of the displayed goods; customer to see unimpededly the goods enclosed in the box; attendants but should be easy to open at sale of the goods, preferably by using one hand only.
The purpose of the invention is to satisfy all these demands, and for this purpose the anti-theft box according to the invention has obtained the characterising features of claim 1.
