The extension body 5 functions in 201019868, which can fill the central gap which is inevitably present in any zipper, shields the fibers of the inner edge 11 of the cloth belt 1, and then sticks on the first side 1a of the tape i and the extension The anti-butter 3 is such that the sexual extension 5 is combined into a body. This action, in addition to preventing the _g inner edge 11 exposed fiber capillary phenomenon and the inside of the center slot 1b. a As shown in Fig. 2, the two tapes 1 of the waterproof zipper shown in the present _ 相对 are attached to the fastening member 2 via the zipper head 6 and then the extension body 5 is provided. When the inner side edge 11 of the tape 1 is bonded, the recess shown in FIG. 2 is formed when it is combined with the extension body 5, and the rib 61 of the 6 is passed through to make the waterproof zipper of the present case open and close with the existing one, and no county (10) Pulling 2 of special specifications and then absorbing the sun* After the zipper is pulled, the inner strips 7 formed by the stretched body 5 are in the surface contact manner = the matching relationship between the two waterproof films 3 on the two sides. The central sipe of the traditional zipper is in a good shape and has an excellent waterproof effect. The β shows the case and the conventional waterproof zipper in the zipper head, wherein the line C represents the inner edge 11 of the tape 1 High score: the edge position of the body 5, and the edge of the extension 5 is just in contact with the zipper 62 and the rib 61. The line c is conventionally waterproof, green (in the edge of the film fit, 3 can Obviously observe the contact area of the inner needle lock 62 and the rib 61 of the zipper head 6. The gossip: there are many, so the case is soft and grind The hard body ^ # body 5 replaces the f-hardened material belt and the waterproof membrane, thereby overcoming the defects of the waterproof and zipper of the waterproof zipper. As shown in Fig. 4, when the polymer elastic extension 5 is adhered After the side edge 11 ^ vertical surface of the 201019868 in the tape 1 , the inner edge of the second surface 1 b of the continuous loop fastening component 2 is further wrapped to form a covering portion 51, and then covered with waterproof The film 3 is disposed on the first surface 1a of the tape and the southern molecular elastic extension body 5, so that the water-repellent film 3 protrudes from the inner edge of the polymer elastic extension 5. In particular, the polymer elastic extension body 5 can further penetrate the buckle. The gap between the components 2 is formed to form a caulking portion 52, which can further improve the waterproofness and durability of the second embodiment of the waterproof zipper of the present invention. As described above, the polymeric elastic extension 5 can further penetrate the buckle. ©© = slot 2 between the pieces 2 to form a caulking portion 52 which is resistant to laterally pulling the central slot of the two tapes 1 and which does not ooze out of the fastening element 2; The extension body 5 and the waterproof film 3 are not excessively convex, so that it is not necessary to use a special zipper head in this case. In addition, it can improve the durability, and γ can effectively prevent the pressure of the fluid from penetrating. As shown in FIG. 5, the cover portion 51 and the caulking portion 52 of the extension body 5 are applied to the hidden zipper. That is, the fastening component 2 is concealed and hidden on the two sides 1b of the tape j. The conventional concealed zipper can also be a waterproof invisible zipper, which is the third embodiment of the waterproof zipper of the present case. If the cloth belt 1 has lateral elasticity, as shown in FIG. 6, the lateral external force F generated during use is absorbed and dispersed by the elastic structure p of the cloth belt 1, and is difficult to be transmitted to the fastening point of the fastening member 2, The central slit 7 of the zipper can be prevented from being stretched by the external force F during use, thereby further improving the waterproof function. As shown in Fig. 7, if the tape 彳 has a longitudinal elasticity at the portion τ, as shown in the U.S. Patent No. 6,494,236, which is owned by the applicant, the waterproof zipper produced by the special tape 1 is provided. The function of flat bending expands the range of use of waterproof zippers. In fact, in order to improve the waterproof function, the case is based on the polymer elastic extension 11 201019868. The extension body 5 fills the central gap which is inevitable in the zipper, and shields the bare fiber of the inner edge 11 of the support tape. Therefore, the preparation process of the waterproof zipper As shown below: Human (1) with a proper amount of hot-melt polyamine phthalate (PU) pressed into the central slit of the zipper buckle σ', the inner edge 11 of the two tapes 1 of the zipper is extended to an extension 5; or σ (2) is injected into the inner edge H of the zipper unit 1 with an appropriate amount of hot-melt polyamine phthalate (ρυ), so that the inner edge 彳彳 directly joins the extension 5. τ When the molecular elastic extension 5 adheres to the inner edge of the tape, it is further adhered to the waterproof film 3 by the following means: the polyamine molecular hybrid 'for example, but not for the thermoplastic S ^ type tape first surface 1a, And according to the formation of a (2) thermosetting polymer elastomer waterproof membrane 3 ί ester (Thermosetting P0lyuretha: e): in, 4, money directly heated and applied (3) on the first side of the tape 1 h evenly spread _ _ _ _ _ 3 and ^ belt agent 4, directly add money _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 5 cutting method 2 bunches under + 歹 ^ mouth dry waterproof film 12 201019868 When the gap, j Gu 镰 scale buckle the central sub-elastic extension 5 - start cutting 'with the knife to waterproof film 3 with high score or ^ 5 The cut-off can be obtained to obtain the waterproof zipper finished product; the unilateral tape on the inner edge of the zipper is 1 ❹ open, so that the waterproof membrane can be cut by the waterproof membrane 3, and the effect of the gain is achieved. , the big one, the ancient eight-chain towel, the central p-saki and its cloth (four) money will be covered by the stretch and waterproof membrane, which can completely eliminate the capillary The stitching of the right cow and the tape does not need to be particularly dense. The effect of the “inside of the chain” affects the ordering of the fastening elements, resulting in reduced failure and increased yield. (3) Polymer elastic extension in this case And the waterproof film will rub against each other when the center slit touches the left and right sides, and the gap between the water and the zipper will be maintained by the lateral external force during the manufacturing process to maintain the waterproof function in the squat state. ' (4) The case is soft The wear-resistant and tough polymer elastic extension replaces the conventional rigid support tape and waterproof film, so that when the needle lock and the rib inside the zipper head are in contact with the extension body of the present case, the waterproof film can be prevented from being worn by the zipper head.
