Abstract

The present invention involves a multiple protection security device which is used to prevent and/or detect burglary of articles, particularly of consumer goods and the like. In one embodiment, the present invention is a remote signal-actuating device for attachment to articles which includes a fluid-containing member which releases detection fluid in response to a predetermined force. In a second embodiment, an electronic security device includes such a fluid-containing member, and, in a third embodiment, a security device for physically restraining an article includes such a fluid-containing member. The detection fluid may be a gas, a liquid or a mixture of these and it may be a coloring agent, an odor containing fluid, a flourescent or phosphorescent dye, a radioactive material or the like.

Claims

1. An electronic security device which comprises:

(a) An electrical circuit member having a circuit which is capable of actuating a signal alarm upon being cut, said electrical circuit member being releasably attachable to merchandise;

(b) An electronic signal alarm attached to said electrical circuit member and actuated by the cutting of said electrical circuit member; and

,

(c) A fluid-containing member which fully encapsulates a fluid having a distinctly noticeable quality, said fluid-containing member being breakable so as to release said fluid in response to a predetermined force, said fluid-containing member being a plastic tube which includes said electrical circuit member contained therein.

2. The device of claim 1 wherein said fluid is a gas having a strong odor.

3. The device of claim 1 wherein the fluid is a liquid having a strong odor.

4. The device of claim 1 wherein said fluid contains flourescent marking material.

5. The device of claim 1 wherein said fluid contains a distinctive coloring agent.
