Zipper having its tab or slide incorporating an RFID device

Abstract

A zipper having its tab or slide incorporating an RFID device is disclosed. The RFID device includes an IC disposed on a central portion of a recess of the tab or slide, an antenna in the form of a plurality of closely engaged concentric miniature enamelled wire conductors secured on a zone defined between projections spaced around a center of the recess and a peripheral flange of the recess, and two connections each electrically interconnected the IC and the antenna. In one embodiment, the tab has a ring for putting on an object. The concealed RFID device can be protected. Also, it may not detract from the zipper's external appearance.

1 . A zipper comprising:
 a tab; and   a Radio Frequency Identification (RFID) device incorporated into the tab.   
   
   
       2 . The zipper of  claim 1 , wherein the tab comprises a circular recess having a circumferential flange with the RFID device mounted in the recess. 
   
   
       3 . The zipper of  claim 1 , wherein the recess is formed of an electrically insulative material. 
   
   
       4 . The zipper of  claim 2 , wherein the tab further comprises a plurality of projections equally spaced around a center of the recess, and an annular zone defined between the projections and the flange. 
   
   
       5 . The zipper of  claim 4 , wherein the projections are either cylinders or rectangular blocks. 
   
   
       6 . The zipper of  claim 2 , wherein the tab further comprises a hanging member projected from the flange. 
   
   
       7 . The zipper of  claim 6 , wherein the hanging member is either a ring or a hook. 
   
   
       8 . The zipper of  claim 4 , wherein the RFID device comprises an integrated circuit (IC) disposed on a central portion of the recess, an antenna secured on the zone, and two connections each electrically interconnected the IC and the antenna. 
   
   
       9 . The zipper of  claim 1 , further comprising a packaging member for covering the RFID device. 
   
   
       10 . The zipper of  claim 9 , wherein the packaging member is epoxy resin. 
   
   
       11 . A zipper comprising:
 a slide; and   a Radio Frequency Identification (RFID) device incorporated into the slide.   
   
   
       12 . The zipper of  claim 11 , wherein the slide comprises a recess having a peripheral flange with the RFID device mounted in the recess. 
   
   
       13 . The zipper of  claim 11 , wherein the recess is formed of an electrically insulative material. 
   
   
       14 . The zipper of  claim 12 , wherein the slide further comprises a plurality of projections equally spaced around a center of the recess, and an annular zone defined between the projections and the flange. 
   
   
       15 . The zipper of  claim 14 , wherein the projections are either cylinders or rectangular blocks. 
   
   
       16 . The zipper of  claim 12 , wherein the slide further comprises a hanging member projected from the flange. 
   
   
       17 . The zipper of  claim 16 , wherein the hanging member is either a ring or a hook. 
   
   
       18 . The zipper of  claim 14 , wherein the RFID device comprises an Integrated Circuit (IC) disposed on a central portion of the recess, an antenna secured on the zone, and two connections each electrically interconnected the IC and the antenna. 
   
   
       19 . The zipper of  claim 11 , further comprising a packaging member for covering the RFID device. 
   
   
       20 . The zipper of  claim 19 , wherein the packaging member is epoxy resin.
