Description

The invention relates to a device for anti-theft, for the proof of originality and for the detection of goods according to the preamble of claim 1. Such devices are used for anti-theft, for the proof of originality and for the detection of goods, especially in sales facilities.

Under theft protection on the one hand unauthorized opening of the goods, especially a bottle, and on the other hand understood the unauthorized stealing the goods, especially a bottle from a sales facility.

The proof of originality means visible and hidden security features in the holographically shaped secondary antenna and a unique ID (identifier) of the RFID chip.

Detection is the identification of goods, in particular bottles. In this case, with the identification of a data volume, for. B. consisting of the item number and / or the retail price to be submitted.

Generally, it is known goods with a bar code, z. B. on an adhesive label or label to equip. This barcode stores information that identifies the goods and that can be read out automatically with a suitable reader. The disadvantage, however, is that only a small amount of data can be stored in the bar code. In addition, the adhesive label or the label on which the bar code is applied, easily remove, so that a sufficient protection of goods, especially bottles, is not given.

Also is from the US 2010 173 229 A a shrinkable label comprising a shrinkable film having a hologram layer, wherein the hologram layer disposed on one side of the shrinkable film is formed of a resin composition.

Another disadvantage is that the sticker can be easily detached from the bottle to be backed up and thus loses its protective function.

Furthermore, from the EP 18 18 277 B1 a heat shrinkable pouch for vacuum packaging of products, which in turn has an electronically detectable label placed on the inside of the pouch. However, it is disadvantageous that even this sticker is easily removable and therefore does not provide adequate protection against theft. Even with the separation of the bag a secure destruction of the electronic detection is not guaranteed. In addition, this application as a bag is not transferable to a bottle to be secured.

The invention is therefore based on the object to develop a generic device for anti-theft, for proof of originality and for the detection of goods that is reliable, inexpensive and not easy to remove and also ensures a safe destruction of electronic detection after the purchase of the goods.

This object is solved by the characterizing features of claim 1. Expedient refinements emerge from the subclaims 2 to 4.

The new anti-theft device, the proof of originality and the detection of goods eliminates the disadvantages of the prior art. It is advantageous in the application of the new device for theft prevention, for the proof of originality and for the detection of goods, in particular of bottles, in which a shrink-film electronic detection is arranged, it is that the shrink film for electronic detection comprises an RFID transponder, the one Secondary antenna and a microchip. This ensures a constant data synchronization between the RFID transponder and a reading device, in particular in the UHF, whereby the goods to be secured are secured in a simple manner and reliable against failure and theft.

It is advantageous if the RFID transponder has a holographic secondary antenna and the shrink film has a perforation for separating the shrink film, which runs through the secondary antenna, because this perforation of the shrink film in the separation of the shrink film, the secondary antenna of the RFID transponder is destroyed and thus ensuring a secure destruction of the electronic detection.

It is also advantageous if the holographic secondary antenna has an optically visible embossing of the product name, manufacturer or quality standards in combination with diverse holographic security features and thus serves as proof of originality.

The new device for anti-theft, for proof of originality and for the detection of goods will now be explained in more detail using an exemplary embodiment.
