[0002] Nylon zippers are widely used in garments, luggage and miscellaneous processing. With the growth and competition of economic activities, users have more and more requirements for the applicability and special functions of zippers. Therefore, the general traditional methods can no longer meet the needs of customers. Special requirements, such as: strength improvement, anti-rupture teeth, waterproof, anti-bacteria, safety, environmental protection, etc.; and the general nylon zipper is a single-sided tooth structure, the chain teeth are on the top, and the cloth belt is on the bottom. Linked together, this technology is widely known to the industry; In addition, the prior art patent Taiwan Publication No. 441257 (improvement of nylon zipper tape) is a double-sided tooth structure, please refer to it Figure 1 ~ Figure 3 As shown, only this patented structure is technically unable to stop the tooth head 711 of its corresponding chain tooth 71 because of its center line (cord) 70 lateral side 701 when the chain is formed (refer to image 3 ), so that the left and right chain teeth loosen laterally to the left and right, resulting in three-piece superimposed sewing, the stitching action of the sewing needle will often pierce the chain teeth, resulting in unsmooth production, abnormally many, and retreat Instead, the upper and lower unilateral chains 7 (non-cogging chains) and the unilateral cloth belt 8 are synchronously sewed into a unilateral chain belt, and then oppositely assembled into a complete chain belt. The suture position of the suture is unstable (because the unilateral sprocket ring is egg-shaped), resulting in uneven and twisted left and right sutures of the complete zipper tape after opposite splicing, and the upper and lower inner sides of the slider 9 The left and right sides of the cavity are respectively H-shaped guide grooves 91, so the complete zipper tape after the aforementioned splicing affects its slider 9 when it cooperates with the opening and closing action. This results in the absence of teeth that can be engaged on one side and sharp teeth on the other side, especially on curved surfaces that are prone to slippage
[0003] In addition, the zipper of the suitcase (bag box) is often worn and broken due to unexpected collisions during the luggage conveying process, causing the entire suture to be detached and unusable

Embodiment Construction
[0043] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0044] Such as Figure 3 ~ Figure 8 and Figure 11 Shown, the present invention is a kind of sandwich-type nylon double-sided tooth zipper and a slider that can open and close the slide fastener, wherein the sandwich-type nylon double-sided tooth zipper system includes left and right cloth belts 1 located in the middle and stitched 23 (reference Figure 6 ) are sewn on the upper and lower sprockets 2 and the lower sprockets 2 above and below the left and right cloth belts 1, and the upper and lower sprockets 2 each have spiral plastic coils with left-handed and right-handed directions Be a group of two rows of chain teeth 21 (refer to Figure 4 ), and each chain tooth 21 of each row of chain teeth 21 (refer to Figure 4 , Figure 5 ) has a tooth head 211 and a chain tooth body 212 connected to the front end of the tooth head 211, and the tooth heads 2...

The invention discloses a sandwich-type nylon two-sided tooth zipper and a puller, and a hot-press molding method thereof. The invention aims to provide the sandwich-type nylon two-sided tooth zipper, the puller, and the hot-press molding method thereof that are high in anti-theft performance, high in strength, easy to open when using and good in waterproof effect. The sandwich-type nylon two-sided tooth zipper includes a left cloth band and a right cloth band and an upper layer chain rack and a lower layer chain rack stitched above and below the left cloth band and the right cloth band. The upper layer chain rack and the lower layer chain rack are both provided with two rows of chain teeth with groups of left turning spiral plastic coils and right turning spiral plastic coils. The chain teeth are provided with tooth heads and chain tooth bodies connected with the front end of tooth heads. And the tooth heads and the tooth bodies of the two rows of the chain teeth are buckled at intervals. It is characterized that central lines of each row of the chain teeth are pressured and become an elliptic body extending transversely, so that one sides of the central lines extend and block tooth head corresponding to the chain teeth.
