Abstract

There is provided a slider for a slide fastener. A slider body includes an upper blade disposed at a front side of the slider body, which is a pull-tab attachment side, a lower blade disposed at a back side of the slider body, which is opposite to the front side, and a connecting post connecting the upper blade and the lower blade to each other. A fibrous fabric sheet is integrally fixed to a back surface of the lower blade at the back side, with an adhesive layer being interposed between the fibrous fabric sheet and the back surface of the lower blade.

First claim

What is claimed is:

1. A slider for a slide fastener, comprising a slider body which includes:
an upper blade disposed at a front side of the slider body, which is a pull-tab attachment side;
a lower blade disposed at a back side of the slider body, which is opposite to the front side; and
a connecting post connecting the upper blade and the lower blade to each other,
wherein a fibrous fabric sheet is integrally fixed to a back surface of the lower blade at the back side, with an adhesive layer being interposed between the fibrous fabric sheet and the back surface of the lower blade, and
wherein a circumferential portion of the back surface of the lower blade is exposed without being covered with the fibrous fabric sheet.

2. The slider according to claim 1 , wherein the back surface of the lower blade comprises a chamfered portion at a circumferential portion thereof, the chamfered portion being curved or inclined so as to come close to the upper blade toward the outside of the slider body, and a flat surface surrounded by the chamfered portion, and the fibrous fabric sheet is fixed to the flat surface.

3. The slider according to claim 1 , wherein the fibrous fabric sheet does not protrude toward the outside of the slider body beyond the adhesive layer.

4. The slider according to claim 1 , wherein the adhesive layer is formed of an adhesive or an adhesive sheet, and the adhesive is an epoxy-based adhesive.

5. The slider according to claim 4 , wherein the adhesive fixes the fibrous fabric sheet by penetrating between fibers of the fibrous fabric sheet from a first surface of the fibrous fabric sheet, which faces the adhesive layer.

6. The slider according to claim 5 , wherein the adhesive does not exude from a second surface of the fibrous fabric sheet, which is opposite to the first surface of the fibrous fabric sheet, which faces the adhesive layer.

7. A slider for a slide fastener, comprising a slider body which includes:
an upper blade disposed at a front side of the slider body, which is a pull-tab attachment side;
a lower blade disposed at a back side of the slider body, which is opposite to the front side; and
a connecting post connecting the upper blade and the lower blade to each other,
wherein a fibrous fabric sheet is integrally fixed to a back surface of the lower blade at the back side, with an adhesive layer being interposed between the fibrous fabric sheet and the back surface of the lower blade,
wherein the adhesive layer is formed of an adhesive or an adhesive sheet, and the adhesive is an epoxy-based adhesive, and
wherein the adhesive fixes the fibrous fabric sheet by penetrating between fibers of the fibrous fabric sheet from a first surface of the fibrous fabric sheet, which faces the adhesive layer.

8. The slider according to claim 7 , wherein the adhesive does not exude from a second surface of the fibrous fabric sheet, which is opposite to the first surface of the fibrous fabric sheet, which faces the adhesive layer.
