Problems solved by technology

In addition, since the covering layer 66 is formed over the front and back surfaces of the core tape 62 and the protrusions 63, forming the covering layer 66 on both sides of the fastener tape 61 leaves a problem in the flexibility of the fastener tape 61.

Embodiment

[0064] like figure 1 As shown, the slide fastener 1 related to the invention of the present application is provided with a pair of left and right fastener tapes 3, fastener elements 10 arranged at equal intervals along the side edges of each fastener tape 3, and a fastener element row 2 composed of a plurality of fastener elements 10. The structure of the slider 6 that engages or separates the pair of element rows 2 by sliding, the upper stopper 7 that restricts the sliding of the slider 6 to the upper end side, and the lower stopper 8 that restricts the sliding of the slider 6 to the lower end side .

[0065] In the illustrated example, the structure in which the lower ends of the pair of left and right zipper tapes 3 are connected and fixed by the lower stopper 8 is shown. Separate the structure of the embed. In addition, as the slide fastener 1, the structure of the single-opening slide fastener which used the separate insert on only one side of the both ends of the elem...

Abstract

Provided is a slide fastener that has a flexible fastener tape, exhibits liquid-tightness, and can prevent a gap from being formed in a coupling portion, and a method of producing the slide fastener. An overlay material is formed on a front surface of a fastener tape so that the overlay material formed on a surface of a core member extends beyond a centerline in a front-rear thickness direction of a tape member. When a pair of fastener element rows engages with each other, a tip of an intermeshing head of a fastener element presses the overlay material formed on the opposite core members.

Description

technical field [0001] The present invention relates to a slide fastener used for openings of clothes, boxes, bags, etc. requiring water repellency and oil repellency, and a method for producing the slide fastener. Background technique [0002] Conventionally, as one of the requirements for slide fasteners that are opened and closed by sliding the slider, a structure in which water or the like does not enter through the slide fastener has been required. As a structure in which water and the like do not enter through the zipper, a liquid-tight zipper in which a synthetic resin coating material is provided on one side of the zipper tape and a water-repellent or oil-repellent is attached to the core string has been proposed (see Patent Document 1 ), a slide fastener in which the entire front and back surfaces of the fastener tape are covered with a synthetic resin covering material (see Patent Document 2), and the like. [0003] The liquid-tight zipper in Patent Document 1 is ...
