Abstract

A fastener assembly for use in tagging an article of commerce and in detecting the unauthorized removal of the article from a store or other business establishment. The fastener assembly comprises a plastic fastener comprising an elongated filament having a first end and a second end, a transverse bar disposed at the first end of the elongated filament and a paddle disposed at the second end of the elongated filament. The paddle is shaped to include a recess. The fastener assembly also comprises an electronic article surveillance (EAS) security device which is disposed within the recess of the paddle. A cover is mounted over the recess so as to trap the security device within the paddle. A method of manufacturing the fastener assembly can be accomplished by continuously molding a length of fastener stock to form a plastic fastener having a recess formed therein, disposing a security device within the recess of the plastic fastener and mounting a cover over the recess so as to trap the security device within the fastener.

Claims

1. A fastener assembly for use in tagging an article of commerce, said fastener assembly comprising:

a) a plastic fastener comprising an elongated filament having a first end and a second end, a transverse bar disposed at the first end of the elongated filament and a paddle disposed at the second end of the elongated filament, the paddle having a recess; and

b) a security device disposed within the recess of the paddle.

2. A fastener assembly for use in tagging an article of commerce, said fastener assembly comprising:

a) a plastic fastener comprising an elongated filament having a first end and a second end, a transverse bar disposed at the first end of the elongated filament and a paddle disposed at the second end of the elongated filament, the paddle having a recess;

b) a security device disposed within the recess of the paddle; and

c) a cover mounted over the recess so as to trap said security device within the paddle of said fastener.

3. The fastener assembly of claim 2 wherein said security device is an electronic article surveillance (EAS) security device.

4. The fastener assembly of claim 3 wherein said security device comprises a strip of magnetic material.

5. The fastener assembly of claim 3 wherein said security device comprises a radio frequency marker.

6. An electronic article surveillance (EAS) system comprising:

a) a fastener assembly for use in tagging an article of commerce, said fastener assembly comprising;

i) a plastic fastener comprising an elongated filament having a first end and a second end, a transverse bar disposed at the first end of the elongated filament and a paddle disposed at the second end of the elongated filament, the paddle having a recess, and

ii) a security device disposed within the recess of the paddle; and

b) a monitoring device located at a monitoring point, said monitoring device being capable of detecting the presence of the security device in said fastener assembly if moved in close proximity to the monitoring point.

7. The electronic article surveillance system of claim 6 wherein said monitoring device is capable of providing a visual and/or audio signal upon detecting the presence of the security device.

8. The electronic article surveillance system of claim 7 wherein the security device comprises a strip of magnetic material.

9. The electronic article surveillance system of claim 8 wherein said monitoring device comprises a transmitter and a receiver.

10. The electronic article surveillance system of claim 7 wherein the security device comprises a radio frequency marker.

11. A method of manufacturing a fastener assembly, comprising the steps of:

a) providing a plastic fastener comprising an elongated filament having a first end and a second end, a transverse bar disposed at the first end of the elongated filament and a paddle disposed at the second end of the elongated filament, the paddle having a recess;

b) disposing a security device within the recess of the plastic fastener; and

c) mounting a cover over the recess so as to trap the security device within the fastener.

12. The method of claim 11 wherein said step of providing a plastic fastener is accomplished through a process of continuous molding.

13. The method of claim 12 wherein the process of continuously molding the plastic fastener comprises the steps of:

a) rotating a molding wheel having surface cavities therein;

b) providing a manifold having a surface that is substantially complimentary to a portion of the surface of the molding wheel;

c) injecting plastic material onto the molding wheel through the manifold to fill the cavities, the plastic material hardening subsequently;

d) skiving excess plastic; and

e) extracting the hardened plastic.
