Abstract

An EAS/expulsion detrimental substance tag (101) in which the tag is held to an article by an attaching assembly, a part of which may be releasably prevented from being withdrawn from the body of the tag. The tag body may be provided with one or more sensors, that are disposed in the body. The sensors are positioned adjacent the detrimental substance. The Benefit Denial (Ink portion) of this tag may feature an ink vial. When the tag and its ink vial are attacked, the tag will expel the detrimental substance out and onto the article being protected.

Claims

1. A security tag, comprising:

a tack assembly;

a tag body, a portion of the tack assembly being insertable into the tag body, the tag body having an attachment mechanism therein for engagement with the tack assembly;

an elongate vial containing a detrimental substance disposed in the tag body, the elongate vial having a length; and

one or more breaker plates disposed in the tag body and positioned adjacent the vial, the one or more breaker plates sized to extend along the length of the vial and being deformable by external forces applied to the tag body whereby the one or more breaker plates will rupture the vial and disperse the detrimental substance when external forces are exerted on the tag body.

2. The security tag of claim 1, wherein the tag body includes an interior cavity defining a vial compartment for containing the vial.

3. The security tag of claim 2, further comprising one or more sensors positioned within the vial compartment adjacent the vial.

4. The security tag of claim 1, further comprising one or more sensors, the one or more sensors to be disposed in the tag body.

5. The security tag of claim 4, wherein at least one of the one or more sensors comprises a magnetic sensor.

6. The security tag of claim 4, wherein at least one of the one or more sensors comprises an acoustic magnetic sensor.

7. The security tag of claim 4, wherein at least one of the one or more sensors comprises a radio-frequency sensor.

8. The security tag of claim 4, wherein at least one of the one or more sensors comprises an RFID sensor.

9. The security tag of claim 4, wherein at least one of the one or more sensors comprises a ferrite assembly.

10. The security tag of claim 4, wherein the one or more sensors are to be positioned adjacent the vial.

11. The security tag of claim 1, further comprising a spring clamp to be disposed in the tag body, the spring clamp to lock the tack assembly to the tag body.

12. The security tag of claim 11, wherein the spring clamp comprises two jaws, the spring clamp to lock the tack assembly to the tack body with the two jaws.

13. The security tag of claim 12, wherein the tack assembly comprises a tack body, the spring clamp to lock the tack assembly to the tack body with the two jaws by clutching the tack body with the two jaws.

14. The security tag of claim 12, wherein the spring clamp comprises a spring arm to bias the spring clamp toward a locking position.

15. The security tag of claim 11, wherein the tag body comprises a support wall having a slot, the spring arm positioned at least partially in the slot.

16. The security tag of claim 11, wherein the spring clamp comprises a spring clamp body, the spring clamp body including a mounting aperture to pivotably mount the spring clamp to the tag body.

17. The security tag of claim 11, wherein the tag body comprises a mount, the spring clamp comprises a spring clamp body, and the spring clamp body comprises a mounting aperture to pivotably mount the spring clamp on the mount.

18. The security tag of claim 1, wherein the one or more breaker plates are sized to have a length approximately the same as an axial length of the vial and a width approximately equal to the diameter of the vial.

19. The security tag of claim 18, wherein the one or more breaker plates comprise two breaker plates disposed on opposite sides of the vial.

20. The security tag of claim 1, wherein the tag body defines an arcuate channel to receive an arcuate probe.

21. The security tag of claim 20, further comprising a spring gate, the spring gate to be disposed at least partially within the arcuate channel.

22. The security tag of claim 21, wherein the spring gate comprises an abutment, the abutment including a catch.

23. The security tag of claim 21, wherein the spring gate comprises an abutment, the abutment having an L-shaped opening.

24. The security tag of claim 1, further comprising a retaining device to be disposed in the tag body, the retaining device to lock the tack assembly to the tag body.

25. The security tag of claim 24, wherein the retaining device includes a ball clutch that includes two or more balls.

26. The security tag of claim 24, wherein the retaining device includes a wedge.

27. A security tag, comprising:

a tack assembly;

a tag body;

the tack assembly to be locked to the tag body, the tack assembly to be unlocked from the tag body using an arcuate probe; and

a vial containing a detrimental substance to be disposed in the tag body; and

one or more breaker plates disposed in the tag body and positioned adjacent the vial, the one or more breaker plates being deformable by external forces applied to the tag body whereby the one or more breaker plates will rupture the vial and disperse the detrimental substance when external forces are exerted on the tag body.

28. The security tag of claim 27, wherein the tag body includes an interior cavity defining a vial compartment for containing the vial.

29. The security tag of claim 27, wherein the detrimental substance includes ink.

30. The security tag of claim 27, wherein the tag body comprises an upper housing and a lower housing.

31. The security tag of claim 30, wherein the upper housing comprises an upper breaker plate compartment, the upper breaker plate compartment to receive at least one of the one or more breaker plates.

32. The security tag of claim 30, wherein the lower housing comprises a lower breaker plate compartment, the lower breaker plate compartment to receive at least one of the one or more breaker plates.

33. The security tag of claim 27, wherein the tag body includes an interior cavity defining a vial compartment for containing the vial.

34. The security tag of claim 27, wherein the vial has an elongate configuration, and the one or more breaker plates are sized to have a length approximately the same as an axial length of the vial.

35. The security tag of claim 34, wherein the one or more breaker plates comprise two breaker plates disposed on opposite sides of the vial.

36. The security tag of claim 27, further comprising one or more sensors, the one or more sensors to be disposed in the tag body.

37. A security tag, comprising:

a tack assembly;

a spring clamp to lock the tack assembly thereto;

a tag body comprising an arcuate channel to receive an arcuate probe to unlock the tack assembly from the spring clamp, the spring clamp and detrimental substance to be disposed in the tag body;

an elongate vial containing a detrimental substance disposed in the tag body, the elongate vial having a length; and

one or more breaker plates disposed in the tag body and positioned adjacent the vial, the one or more breaker plates sized to extend along the length of the vial and being deformable by external forces applied to the tag body whereby the one or more breaker plates will rupture the vial and disperse the detrimental substance when external forces are exerted on the tag body.
