Abstract

A slide fastener-attached product includes a fastener stringer and a fastener-receiving member. The fastener stringer is attached to a stringer attachment edge of the fastener-receiving member with a sewn portion. The stringer attachment edge includes a double-layer portion including a first strip portion, a bent portion, and a second strip portion. The sewn portion is disposed away from a plurality of fastener elements, and the bent portion is disposed in contact with or closer to the fastener elements. A waterproof region is formed between the sewn portion and the fastener elements. In the slide fastener-attached product, exposure of the fastener tape in the region between the fastener-receiving member and the fastener elements can be prevented or reduced.

First claim

1 . A slide fastener-attached product comprising:
a pair of fastener stringers, each including a fastener tape and a plurality of fastener elements arranged on the fastener tape at equal intervals in a tape length direction; and a fastener-receiving member including a pair of stringer attachment edges to which the fastener stringers are attached respectively and that are positioned to face each other, wherein each of the fastener stringers is attached to a corresponding one of the stringer attachment edges with a sewn portion formed of a sewing thread, wherein each of the stringer attachment edges includes a double-layer portion bent in a U-shape in a sectional view taken along a plane orthogonal to the tape length direction, wherein the double-layer portion includes a first strip portion, a bent portion, and a second strip portion in the sectional view, the first strip portion being disposed away from the fastener tape, the bent portion extending from the first strip portion and having a bent shape, and the second strip portion extending from the bent portion and being disposed in the first strip portion overlappingly, wherein a part of the sewn portion is disposed between the first strip portion and the second strip portion of the double-layer portion, wherein the sewn portion is disposed away from the plurality of fastener elements, and the bent portion is disposed in contact with or close to the plurality of fastener elements, and wherein a waterproof region is formed between the sewn portion and the plurality of fastener elements.

2 . The slide fastener-attached product according to claim 1 , wherein the bent portion is disposed away from the sewn portion and is disposed in contact with the fastener elements.

3 . The slide fastener-attached product according to claim 2 , wherein the fastener tape and the second strip portion are bonded to each other in at least a part of a region between the bent portion and the sewn portion.

4 . The slide fastener-attached product according to claim 2 , wherein the bent portion is formed to enable maintenance of the bent shape of the bent portion by being subjected to a heat treatment.

5 . The slide fastener-attached product according to claim 2 , wherein the sewn portion is disposed away from the fastener elements by a separation distance of 0.5 mm or more and 10.0 mm or less in a tape width direction of the fastener tape.

6 . The slide fastener-attached product according to claim 2 , wherein a dimension from an outer surface of the first strip portion of the double-layer portion to an outer surface of the second strip portion of the double-layer portion in a tape thickness direction of the fastener tape is 0.25 mm or more and 5.0 mm or less.

7 . The slide fastener-attached product according to claim 1 , wherein the bent portion is close to a position of forming the sewn portion and to the plurality of fastener elements in a left-and-right direction, and
wherein the sewn portion is disposed away from the fastener elements by a separation distance of 0.5 mm or more and 3.0 mm or less in a tape width direction of the fastener tape.

8 . The slide fastener-attached product according to claim 1 , wherein each of the fastener elements includes an element base and a fin portion, the element base including a portion having a constant dimension in a tape thickness direction of the fastener tape, the fin portion extending from the element base toward an inner region of the fastener tape and having a dimension less than the dimension of the element base in the tape thickness direction.
