Abstract

An anti-theft alarm system comprising an electric circuit including a signal device and electrical components in said circuit adapted to be attached to an article of merchandise and which are readily destructible to interrupt the circuit and actuate the signal device.

Claims

1. A label comprised of a sheet of readily destructible insulation material, electric circuit components on one surface thereof, one of said components comprising a portion of a conductive loop having two terminals adaptable for attachment to an electric circuit, another component comprising a conductor out of contact with the loop and having a terminal adaptable for attachment to said circuit, and an adhesive coating said one surface and said components.

2. The label recited in claim 1, wherein said conductor component is located within said loop portion and comprises a ground.

3. The label recited in claim 1, wherein all of said terminals are on said surface at one end of said sheet.

4. The label recited in claim 3, wherein said end is free of adhesive.

5. The label recited in claim 3, wherein said end is slotted.

6. The label recited in claim 5, wherein said slotted end has a pair of slots and said terminals are located therebetween.

7. The label recited in claim 1, wherein said sheet of insulation material comprises paper.

8. The label recited in claim 1, wherein said components comprise conductive ink printed on said sheet.

9. The label recited in claim 1, wherein said components comprise strips of conductive material bonded to said sheet.

10. The label recited in claim 1, wherein said adhesive is pressure sensitive.

11. The label recited in claim 1, wherein said adhesive coated surface is covered by a removable covering sheet.

12. A label alarm system comprising an electrically actuated signal device having a normally closed electric circuit, a label adhesively secured to an article of merchandise, means removably securing said label to said signal device, electric circuit components on said label and said removable securing means therefor, and means connecting said components in said circuit, said label components including a portion of a conductive loop having two terminals and another conductor out of contact with said loop and being destructible to interrupt the current to the circuit for actuating the signal device upon removal of the label from said merchandise, at least one surface of said label and said label components being coated by the adhesive.

13. The alarm system recited in claim 12, in which the signal device is an audible alarm.

14. The alarm system recited in claim 12, in which the signal device is remotely located relative to the label.

15. In a label and connector adapted for use in a label alarm system including an electrically actuated signal device, said label comprising a sheet of material having electric circuit components and an adhesive coating on one surface thereof adaptable for securing said label to an article of merchandise, and said connector being detachably secured to said label for electrically connecting said circuit components to said signal device, said components including a portion of a conductive loop having two terminals and another conductor out of contact with said loop, said adhesive coating being disposed on at least one surface of said components.

16. The label and connector recited in claim 15, in which one end of the label is slotted and said connector is secured to said slotted end.
