Problems solved by technology

The other problem with the back stopper 204 is that it is difficult for the back stopper 204 to fit the mold on the surface of the element 203, and since the resin overflows from the mold during injection molding, forming a burr, the formation of the back stopper 204 It is very troublesome, so it is difficult to form a beautiful back code 204

[0037] As described above, in the waterproof zipper according to the first embodiment shown in FIGS. 1 to 6, each zipper tape 2 is made of elastic material (for example, thermoplastic elastic material or synthetic rubber) in a woven or knitted fabric The front and rear surfaces of the zipper are coated to provide waterproof performance, and through holes 9 are formed in the opposite edges 8 of the zipper tape 2 so that they pass through the front and rear surfaces. The fastener elements 3 are formed on the front and rear surfaces of the zipper tape 2 by injection molding with the aid of through holes 9 of thermoplastic resin, such as polyamide, polyacetal, polypropylene, and polybutylene terephthalate. Esters, or the like.

[0038] In the structure of each element 3 formed on the fastener tape 2, an enlarged joint head 11 is formed at its front end, an joint concave portion 15 is provided inside the front end of the joint head 11, and the fastener tape on the mating side The oppos...

[0042] The waterproof slide fastener according to the second embodiment shown in FIG. 7 differs from the waterproof slide fastener of the first embodiment in the shape of the sheet member 5, wherein the sheet member 5 is connected to the space portion 19 of the fastener chain 1. Lined on top. The material of the sheet member 5 is the same as in the first embodiment, and the sheet member 5 is formed by coating the front and rear surfaces of a woven or knitted fabric or non-woven fabric with a thermoplastic elastic material or synthetic rubber, or using resin Film formation. The sheet member 5 is provided with a protruding piece 31 that protrudes upward along the opposite edge 8 of each of the left and right zipper tapes 2 arranged in parallel. The protruding piece 31 protrudes in a stepped form, that is, its front end portion 30 is on the side of the engagement protrusion 14 formed in the neck 12 of the fastener element 3 (that is, adjacent to the fastener element 3) on one side. E...

[0048] The difference between the waterproof slide fastener according to the fourth embodiment shown in FIG. 9 and the waterproof slide fasteners in the respective embodiments is that the shape of the sheet member 5 connected to the rear surface of the space portion 19 of the fastener chain 1 is modified. The material of the sheet member 5 is the same as that of each embodiment.

[0049] The sheet member 5 is formed by linearly cutting the front end portion 30 of the sheet member 5, and is bonded to the rear surface of the fastener tape 2, so that the front end portion 30 is in contact with the neck portion 12 adjacent to the fastener element 3. The side ends of the engaging protrusion 14 formed inside are in contact. The back stop 4 having the same shape as each of the embodiments is formed on the sheet member 5 by injection molding by means of through holes formed in the space portion 19 to ensure waterproof performance.

Abstract

The invention provides a waterproof zipper. In the waterproof zipper, waterproof sheet member is used as space segment linning of waterproof fastener tape, in this way, it is set near zipper teeth, and the back code is foremed on the surface of the sheet member. In the said waterproof zipper, a whole surfaces of a pair of fastener tapes(2)are covered by elastic material, and the zipper teeth(3)made of resin are integrally moulded on the opposite edge(8)and the waterproof sheet member(5)is installed in the space segment(19), therefore it extends on the right and left fastener tapes(2). The front end(30)of the sheet member(5)is set to contact with zipper teeth(3)of end. The back code(4)made of resin is moulding formed by through hole(9)installed on the side of fastener tape(2)and sheet member(5), with a clearance relative to zipper teeth(3). The back code(4)is equipped with protrusion(22), wherein the protrusion(22) has the same thickness with zipper teeth(3)on one side of superface part(24) at the space segment(19).

Description

Technical field [0001] The present invention relates to a waterproof zipper with waterproof performance, which is constructed by connecting a back stopper to a space part of a fastener chain without fastener teeth, wherein the latter stopper is formed by injection molding of a thermoplastic resin, and the fastener chain is formed by using The thermoplastic resin is formed by injection molding the fastener elements on the opposite edges of the fastener tape, and the waterproof fastener tape is formed by coating the entire surface of the woven or knitted fastener tape with an elastic material. Background technique [0002] A slide fastener with waterproof performance as shown in FIG. 10 is known. In the waterproof zipper, injection-molded type fastener elements 103 formed of thermoplastic resin, for example, the fastener elements 103 each including the engaging head 111, the neck portion 112, and the leg portion 113 are molded by using an injection molding method. On the opposite e...
