Fluid-impervious slide fastener, manufacturing method thereof and product having same

Abstract

The invention provides a fluid-impervious slide fastener, a manufacturing method thereof and a product having same; an covering abutting member is formed in a central slit of a pair of support tapes, the covering abutting member has a first covering body having a covering layer and a second covering body having a covering layer; when the fluid-impervious slide fastener is in a coupled status, the first covering body and the second covering body are able to elastically abut against each other so as to form a tightening deformation, thus the central slit is provided with a fluid-impervious function against a fluid, for example a liquid, of capable of bearing a hydrostatic pressure of 30 gf / cm<2>.

Description

technical field [0001] The present disclosure relates to a zipper, in particular to an anti-seepage zipper with an anti-seepage function. The present invention further relates to a method for making the anti-seepage zipper and products with the anti-seepage zipper. Background technique [0002] Zipper is very common in people's daily life, and it is an indispensable opening and closing device. Because of the convenience of opening and closing and the wide range of uses, zippers are widely used in clothing, such as clothes or Trousers, carrying devices such as purses or backpacks, camping equipment such as tents, sleeping bags and many more. [0003] In fact, in order to achieve the functions of windproof and waterproof, the above-mentioned products have paid attention to waterproof in the selection of materials. For example, the outer fabric of the snow suit is made of nylon or water-repellent treatment, and even a waterproof lining is added to achieve waterproof function. ...

AI Technical Summary

Problems solved by technology

of the aforementioned patent figure 1 and figure 2 As shown, there is a gap between the filling block below the waterproof layer and each of the zipper tapes. This method has the same disadvantages as the previous embodiment, because the filling block is not connected to the inner edge of each of the zipper tapes, so that The rigidity of the zipper tape cannot be increased, and the mobility of the inner edges cannot be fixed, so that the pair of zipper tapes still cannot generate enough rigid support force in the horizontal direction to push and clamp the bent portion of the waterproof layer, As a result, the effect of the so-called "can be pressed together to close the gap between the two zipper tapes" cannot be achieved.
