Abstract
A slider zipper reclosable fastener wherein the zipper includes fastener strips and closure elements on the fastener strips which are extruded integrally. The closure elements are arranged at particular angles by extrusion opening angles in order to increase burst strength. Ridges on the fastener strips and shoulders on the slider hold the slider on the zipper.
Claims27
A recloseable fastener assembly comprising:
- a first fastener strip having an inner surface;
- a second fastener strip having an inner surface;
- a first profile positioned along the length of the inner surface of said first fastener strip, said first profile having at least one first closure element,
- a second profile positioned along the length of the inner surface of said second fastener strip, said second profile having at least one second closure element, the at least one said second closure element being adapted to interlockingly engage with the at least one said first closure element;
- and
- a slider for moving between a closed position and an open position along said first fastener strip and said second fastener strip in straddling relation thereto;
- said first fastener strip and said first profile being formed as an integral extruded first product wherein the at least one said first closure element is shaped as a hook with a first proximal portion and a first distal portion;
- said first extruded product being formed by a first extrusion die with an extrusion opening defining an angle between said first fastener strip and the first proximal portion of the at least one said first closure element of about 105°.
