Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
147 words
A one-piece injection molded fastener assembly adapted to be dispensed by a tag attacher, comprising; a plurality of fasteners each having a crossbar, a head, and a filament joining the crossbar and the head, a rod spaced from the crossbars, and a separate connector connecting each crossbar and the rod, the crossbars being molded parallel with respect to each other and perpendicular with respect to the rod, wherein the fastener assembly is composed of injection-moldable polymer composition comprised of a moldable nylon containing a minor amount, between about 1% to about 25% by weight of the moldable polymer composition, of a polyester selected from the group consisting of film and fiber forming polyesters the amount of polyester being an amount which increases the tendency of the crossbars to remain parallel to each other and perpendicular to the rod after removal of the fastener assembly from the mold.
Claim 2
Dependent Claim
