A kind of invisible sealing zipper

Abstract

The invention provides an invisible sealing zipper comprising left and a pair of left and right zipper tapes. A plurality of teeth are fixed to the zipper tapes and arranged on the upper surface of the upper zipper tape and the lower surface of the lower zipper tape. A first flexible waterproof tape extending along each zipper tape in a length-wise direction is connected to the upper surfaces of the corresponding teeth. The opposing inner edges of the first flexible waterproof tapes are provided with matching sealing parts. The upper surface of each first flexible waterproof tape is an arc surface. When the teeth of the zipper tapes on two sides are closed, the sealing parts of the first flexible waterproof tapes form a labyrinth seal, and the upper surfaces of the first flexible waterproof tapes are seamlessly and smoothly abutted. The invisible sealing zipper feels good and has good sealing performance, invisibility and integral appearance, tie points of the zipper cannot be recognized from appearance, the teeth are smooth to pull, and the invisible sealing zipper has high closing property.

Description

technical field [0001] The invention relates to a slide fastener, in particular to an invisible sealing slide fastener. Background technique [0002] Existing zippers all have a single-structure occlusal manner, which can be seen as zippers at a glance from the appearance, and do not have an invisible effect. Similarly, the waterproof effect of zippers is not good, and they do not have sealing performance. In order to improve the sealing performance of the zipper, the Chinese utility model patent with the notification number CN2361129Y discloses a double-layer waterproof zipper, including a zipper puller, a chain and a waterproof layer. The waterproof layer is composed of symmetrically inverted first and second waterproof sheets. The side end of the waterproof sheet is provided with two grooves, and the groove end is provided with a hook upward, so that the two waterproof sheets are overlapped and hooked together to form a whole; the first and second chains of the chain are ...

AI Technical Summary

Problems solved by technology

[0003] However, the slider of this kind of waterproof zipper is very complicated, and a waterproof sheet engagement groove is also provided on the top surface of the slider slider. It must be covered on the cloth tape at the same time, which affects the design freedom of the zipper, otherwise water will easily seep from between the waterproof sheet and the chain teeth, and the waterproof effect is still not ideal; moreover, for plastic zippers, the shrinkage rates of plastic and cloth tape are different , will affect the uniform distribution rate of the chain teeth on the cloth belt, thereby affecting the sliding performance of the slider, and sometimes the zipper is not easy to pull, resulting in stagnation
