Abstract

An electronic article surveillance (EAS) tag having an attaching member 34 located therein and adapted to securely and releasably receive a shaft of a pin therein, whereby a predetermined arcuate probe is inserted through an opening and applies a requisite force to the attaching member to release the shaft. At least one frangible vial containing a detrimental substance positioned within the tag body to deter unauthorized manipulation of the tag.

Claims

1. A device for monitoring items through electronic article surveillance (EAS), comprising:

a tag body;

an attaching member located within said tag body;

a shaft having a top, wherein said shaft is inserted through an item to be monitored until said top engages said item, and said shaft entering said tag body through a hole and being received securely by said attaching member;

a breakable vial containing a detrimental fluid maintained within said tag body;

a detectable EAS sensor within said tag body; and

a probe of a predetermined shape and path is inserted through an entrance within said tag body and engages said attaching member and allows extraction of said shaft without requiring a channel to mate and guide said probe to said attaching member.

2. The device of claim 1, wherein the shaft does not initially emanate from within said tag body.

3. The device of claim 1, wherein the shaft does not have any region which contacts the vial.

4. The device of claim 1, wherein said vial is positioned to cover at least an area between said EAS sensor and said attaching member.

5. The device of claim 1, wherein the EAS sensor is located distal to said entrance and said attaching member is proximal to said entrance.

6. The device of claim 5, wherein said vial is positioned to cover at least an area between said EAS sensor and said attaching member.

7. The device of claim 1, wherein said tag body is made of an inflexible material such as ABS plastic.

8. The device of claim 1, wherein said attaching member is a ball clutch mechanism.

9. The device of claim 1, wherein a pressure point extends inwardly from said tag body and is in contact with said vial such that the pressure point increases the susceptibility of the vial to breakage.

10. The device of claim 1, wherein an orifice is defined through said tag body and occluded by said vial, such that breakage of the vial expels the detrimental substance out of said orifice.
