Abstract
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.
Claims22
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.

An open-end 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;
- wherein the first tape and the second tape are separate from one another when the elements of the first and second tapes are not engaged;
- (c) a pin comprising at least one portion associated with the top side or the bottom side of the first tape, the at least one portion of the pin comprising;
- an outer surface;
- an insertion area recessed relative to the outer surface;
- and
- a protrusion that projects from the insertion area;
- (d) a box associated with the second tape and comprising at least one portion that extends from the top side or the bottom side of the second tape, wherein a deformable arm projects from the at least one portion of the box into a cavity of the box, wherein:
- the cavity of the box is configured to receive the pin in an initially engaged position such that the protrusion forces the deformable arm from an initial position into a flexed position;
- the deformable arm is configured to audibly snap back from the flexed position toward the initial position as the pin moves from the initially engaged position into a received position, wherein the deformable arm is seated within the insertion area when the pin is in the received position;
- and
- when the pin is in the received position, the edges of the first and second tapes are compressed against one another to form a water and air tight seal.

An open-end 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;
- wherein the first tape and the second tape are separate from one another when the elements of the first and second tapes are not engaged;
- (c) a pin associated with the first tape;
- and
- (d) a box associated with the second tape, wherein the box is configured to receive the pin such that the edges of the first and second tapes are compressed against one another to form a water and air tight seal.
