Abstract

An anti theft ink tag designed to permanently render an article useless if unauthorized removal of the tag is attempted. The anti theft ink tag includes ampules containing a permanent staining substance. The ampules are supported in a base component with holes that allow the staining substance to escape if the ampules are fractured. A cover component with a break away element covers the base component. Permanently attached to the break away element is an elongated pin type connecting unit that is used to attach the tag to the article being protected, and locked into place by a locking mechanism. When an unauthorized removal of the tag is attempted, the break away element fractures the ampules and also exposes the outside of the cover component to the staining substance.

Claims

1. A device for deterring theft of articles, comprising:

a plurality of ampules;

a permanent staining substance to be contained in said ampules;

a housing which encloses said ampules, said housing comprising a base component supporting said ampules and a cover component to cover said base component, said cover component containing a break away element;

a means to allow said staining substance to escape if said ampules are fractured;

a means for attaching said device to the articles to be protected whereby unauthorized removal of said device causes said ampules to fracture; and

a means for detecting the escape of said staining substance if said ampules are fractured.

2. The device of claim 1, wherein said base component has a plurality of holes which allow said staining substance to escape if said ampules are fractured.

3. The device of claim 2, wherein said means for attaching said device to the articles to be protected comprises an elongated pin type connecting unit.

4. The device of claim 3, wherein said base component has a centrally located hole which supports said elongated pin type connecting unit.

5. The device of claim 4, wherein said break away element of said cover component is permanently attached to said pin type connecting unit.

6. The device of claim 5, wherein said break away element causes said ampules to fracture if unauthorized removal of said device is attempted.

7. The device of claim 6, wherein said means for detecting the escape of said staining substance comprises the escape of said staining substance through a viewing hole in said cover component, said viewing hole resulting from the breaking away of said break away element from said cover component.

8. A device for deterring theft of articles, comprising:

a plurality of ampules;

a permanent staining substance to be contained in said ampules;

a housing which encloses said ampules;

a means for attaching said device to the articles to be protected whereby unauthorized removal of said device causes said ampules to fracture;

a base component supporting said ampules and having a plurality of holes which allow said staining substance to escape if said ampules are fractured;

a cover component to cover said base component;

an elongated pin type connecting unit;

a central hole in said base component which supports said elongated pin type connecting unit; and

a break away element of said cover component into which said connecting unit is permanently attached and wherein said break away element causes said ampules to fracture if unauthorized removal of said device is attempted;

a means for detecting the escape of said staining substance if said ampules are fractured.
