Inventory alarm and ink tag combination

1. A dual function inventory control tag comprising:

a first component including a dome shaped portion;

a second component including a dome shaped portion;

a fastening mechanism for fastening together the first component and the second component, the fastening mechanism being configured whereby the first component and the second component can be easily locked together and can only be unlocked from each other in normal usage by an external tool;

first and second chambers defined by the first and second components;

an electronic device located in the first chamber for triggering a compatible sensor and alarm system external to the control tag; and

a dye container located in the second chamber designed to fracture and spill dye when the first and second components are forced apart, the dye container forming a part of the fastening mechanism.

2. A control tag as claimed in claim 1 wherein the fastening mechanism comprises a pin assembly formed on the first component, the pin assembly having a support head and a pin shaft.

3. A control tag as claimed in claim 2 wherein the fastening mechanism further comprises a clutch mechanism formed on the second component, the clutch mechanism being configured to receive the pin shaft of the pin assembly when the first and second components are fastened together.

4. A control tag as claimed in claim 3 wherein the clutch mechanism comprises a three ball clutch which is located in a cup shaped member of the second component.

5. A control tag as claimed in claim 2 wherein dye container is formed in the support head of the pin assembly.

6. A control tag as claimed in claim 5 wherein the dye container is formed as recess in the support head of the pin assembly.

7. A control tag as claimed in claim 6 wherein the recess in the support head comprises a reservoir plug in an aperture in the recess which fractures or is compromised when the first and second components are forced apart to discharge the dye from the recess.

8. A control tag as claimed in claim 5 wherein the dye container comprises at least one frangible receptacle located in the chamber of the first component, the frangible component fracturing in response to forcing the first and second components apart from each other.

9. A control tag as claimed in claim 1 wherein electronic device is located in the chamber of the second component.

10. A control tag as claimed in claim 1 wherein the first component has an access cap for providing access to the chamber in the first component.

11. A control tag as claimed in claim 1 wherein the first and second component form a generally flattened control tag when fastened together by the fastening mechanism.

12. A control tag as claimed in claim 1 wherein the first and second component form a generally circular control tag when fastened together by the fastening mechanism.

13. A control tag as claimed in claim 1 wherein the first and second component form a generally oval control tag when fastened together by the fastening mechanism.

14. A control tag as claimed in claim 1 wherein the dye container contains ink.

15. A control tag as claimed in claim 14 wherein dye container comprises at least two ink containers.

16. A method for controlling inventory comprising the steps of:

providing a first control tag component;

providing a second control tag component;

fastening together the first control tag component and the second control tag component whereby the first control tag component and the second control tag component can be easily locked together and can only be unlocked from each other in normal usage by an external tool;

forming a first and second chamber in the first and second control tag components;

inserting an electronic device in the first chamber for triggering a compatible sensor and alarm system external to the control tag; and

inserting a dye container in the second chamber, the dye container being designed to fracture and spill dye when the first and second control tag components are forced apart from each other, the dye container forming a part of the fastening mechanism.

17. A method as claimed in claim 16 wherein the first control tag component is fastened to the second control tag component by a pin and clutch mechanism.

18. A method as claimed in claim 16 wherein the dye container is inserted in the chamber of the first control tag component and the electronic device is inserted in the chamber of the second control tag component.

19. A method as claimed in claim 16 wherein the first and second control tag components are shaped so as to have a desired external configuration suitable for attachment to a selected product.

20. A method for making a dual function control tag for controlling inventory, the method comprising the steps of:

providing a first control tag component;

providing a second control tag component;

fastening together the first control tag component and the second control tag component whereby the first control tag component and the second control tag component can be easily locked together and can only be unlocked from each other in normal usage by an external tool;

forming at least one chamber in at least one of the first and second control tag components;

inserting an electronic device in one of the chambers for triggering a compatible sensor and alarm system external to the control tag; and

inserting a dye container in one of the chambers, the dye container being designed to fracture and spill dye when the first and second control tag components are forced apart from each other.
