Sealing for open-end slide fastener

摘要

Open-ended slide fasteners that are watertight and/or airtight. The slide fasteners include box and pin mechanisms integrated with the slide fastener and configured to compress the tape edges and create a water and air tight seal, thus eliminating the need for installing a separate component after the slide fastener has been manufactured.

主权项

1. A slide fastener assembly comprising:
(a) a first tape comprising a top side, a bottom side, edges and a plurality of elements; (b) a second tape comprising a top side, a bottom side, edges and a plurality of elements; (c) a pin comprising a first portion on the top side of the first tape and a second portion on the bottom side of the first tape, each of the first and second portions comprising:
an outer surface;an insertion area recessed relative to the outer surface;a protrusion that projects from the insertion area, wherein a depth extends between the two protrusions; (d) a box that is integral with the second tape and that comprises a first portion on the top side of the second tape and a second portion on the bottom side of the second tape, wherein a cavity separates an inner surface of the first portion from an inner surface of the second portion and wherein a first deformable arm projects from the first portion into the cavity and a second deformable arm projects from the second portion into the cavity; wherein a distance between inner surfaces of the first and second deformable arms is less than the depth between the two protrusions.
