Problems solved by technology

[0012] Therefore, if the airtight and waterproof slide fastener 70 is repeatedly bent or folded, the ridge 76b will be peeled off from the bent airtight and waterproof tape 72 or the backing tape 74 due to the restoring force, and the airtightness of the slide fastener will be reduced. Reduced or lost airtightness and water resistance

Abstract

The forming method of the stopper (30, 40, 60) of the present invention includes the process of injection molding a stopper molding (30a, 40a, 60a) on at least one end side of the dentition (12), and the stopper molding (30a , 40a, 60a) have a molded body body (31a, 41a, 61a) that embeds the end of the dentition (12), and a sheet extending outward from the peripheral edge of the molded body body (31a, 41a, 61a) Shaped ridges (32a, 42a, 62a), and the above-mentioned ridges (32a, 42a, 62a) of the above-mentioned stopper molded body (30a, 40a, 60a) are welded by high frequency to form a high-frequency welded part (32, 42, 62) process. According to this, since the fastening strength of the stopper (30, 40, 60) can be increased, and the thickness of the high-frequency welded part (32, 42, 62) can be thinned, the high-frequency welded part can be easily bent. (32, 42, 62), therefore, it is possible to stably form a stopper (30, 40, 60) that is difficult to peel off for a long time.

Description

technical field [0001] The present invention relates to a method of forming a stopper for an airtight and waterproof slide fastener used in flexible containers such as liquid transport, protective clothing, and special work clothes such as diving suits. Background technique [0002] Conventionally, airtight and waterproof zippers have been used in the opening and closing parts of flexible containers used for liquid transportation, etc., and in the openings of special work clothes, in order to ensure airtight and waterproof performance even in severe environments such as high pressure, high temperature and high humidity. An example of such an airtight and waterproof slide fastener is disclosed in, for example, Japanese Utility Model Publication No. 4-36657 (Patent Document 1), Japanese Patent Laid-Open No. 2003-309 (Patent Document 2), and the like. [0003] For example, the airtight and waterproof slide fastener 70 described in Patent Document 1 is as follows: Figure 14 As ...
