Description

Water blocking zipper and manufacturing method thereof

The present invention relates to a zipper and a method of manufacturing the same, and more particularly to a water-blocking zipper capable of preventing fluid from leaking through and a method of manufacturing the same.

Please refer to FIG. 1 , which is a conventional water-blocking zipper 9 . The conventional water-blocking zipper 9 includes two chains 9a and 9b which are oppositely coupled, and each of the chains 9 a and 9 b has a tape 91 and is coupled thereto. A fastening member 92 on a surface of the tape 91; an inner edge of the tape 91 is connected to an extension body 93 formed by solidification of a hot-melt PU, and the other surface of the tape 91 is coated with an adhesive 94. And the adhesive 94 also covers the extension body 93, and a waterproof film 95 is further attached to the adhesive 94. An embodiment similar to the conventional water-blocking zipper 9 has been disclosed in the Patent No. I374714 of the Republic of China on the "continuous loop-type waterproof zipper" patent case.

The tape 91 and the fastening component 92 of the conventional water-blocking zipper 9 are all monofilaments, and the material has a higher melting point than the extension 93 made of the hot-melt PU, so the liquid hot-melt PU is used. After being injected into the gap between the engaging elements 92 of the two chains 9a, 9b, the extension 93 will contract when cooled and solidified, thereby forming a gap between the extending body 93 and the tape 91, and The inner edge of the tape 91 and the fastening member 92 are also not bonded to each other to form a void, which causes peeling of the extension body 93 when it is easy to use. Therefore, the conventional water-blocking zipper 9 has a problem of short service life.

On the other hand, since the conventional water blocking zipper 9 has its waterproof film 95 attached to the outermost The surface of the waterproof film 95 is generally about 0.03 to 0.05 mm, so that the slider is easy to contact and rub the waterproof film 95 when used, so that the waterproof film 95 is worn and the service life is short, and the waterproof film 95 corresponds to the extension. At the body 93, it is also easy to form a depression and generate flaws, which makes it difficult to process the crucible, which has problems such as difficulty in manufacturing cost and difficulty in improving the process efficiency.

In addition, since the tape 91 and the extension 93 of the conventional water-blocking zipper 9 are covered by the waterproof film 95, the appearance of the conventional water-blocking zipper 9 can only exhibit the color and texture of the waterproof film 95. For example, when the color of the tape 91 and the extension 93 are different, if a two-color effect is desired, a glossy transparent waterproof film 95 is used, but the transparent transparent film 95 is too bright, which easily leads to the overall water-blocking zipper. The texture of 9 is not good; when the matte waterproof film 95 is selected, because the matte waterproof film 95 is mostly colored, the tape 91 and the extension 93 are covered, so that the conventional water-blocking zipper 9 The appearance and texture are relatively monotonous, and it is difficult to increase the willingness of consumers to purchase.

In view of this, the conventional water-blocking zipper does have the need to improve.

In order to solve the above problems, the present invention provides a water-blocking zipper and a manufacturing method thereof, which can make a waterproof film of a water-blocking zipper and a waterproof layer fused to each other, so that the waterproof layer is not easily peeled off and can be used for a long time.

The invention provides a water-blocking zipper and a manufacturing method thereof, and the waterproof layer of the water-blocking zipper is formed outside the waterproof membrane to be easily formed, and the friction-proof waterproof membrane of the slider can be avoided, and the operation convenience of the boring processing can be improved.

The invention provides a water-blocking zipper and a manufacturing method thereof, so that the waterproof layer and the waterproof membrane of the water-blocking zipper have exposed portions, so that they can be selected to have different colors or textures.

The invention defines that the extending direction of the long side of the tape is the x direction, the extending direction of the short side of the tape is the Y direction, and the extending direction of the thickness of the tape is the Z direction; the X, Y and Z directions are orthogonal to each other. Further, the side end faces of the two cloth belts adjacent to each other in the Y direction are "inner side", and the side end faces away from each other are "outside side".

The water-blocking zipper of the present invention comprises two chains which can be combined with each other, each of the chains having: a tape; a chain of teeth, the group of teeth joining the tape; a waterproof film, the waterproof film being bonded by a surface a waterproof layer provided on the other surface of the waterproof film, and an inner side of the waterproof layer forms an abutting surface; wherein, when the two-chain tooth sets of the two chains are interlaced with each other, the two The abutting surface of the waterproof layer of the chain abuts; the waterproof layer covers the waterproof film in a range smaller than the waterproof film covers the tape.

The method for manufacturing a water-blocking zipper of the present invention comprises the steps of: preparing a two-belt belt respectively having a chain of teeth, and interlacing the two-chain tooth sets; and providing a waterproof film on the surface of the second cloth; a waterproof layer is disposed on the waterproof film, and the waterproof layer covers the waterproof film to a range smaller than the waterproof film covering the second tape; and the waterproof layer and the waterproof film are cut to the inner side of the waterproof layer Forming two opposing abutting faces.

Accordingly, the water-blocking zipper of the present invention and the method for manufacturing the same can be obtained by using the same or similar materials, so that the waterproof layer of the water-blocking zipper can be fused with the waterproof membrane, and no void is formed after cooling and solidification. The water-repellent layer of the water-blocking zipper will not be easily peeled off and can be used for a long time, and has the effects of prolonging the service life of the water-blocking zipper.

The water-blocking zipper of the present invention and the manufacturing method thereof can be easily formed by providing the waterproof layer on the surface of the waterproof membrane, and the slider can be brought into contact with the waterproof layer to reduce the chance of scratching the waterproof membrane, thereby improving the definition. The processing convenience is convenient, and it can reduce the manufacturing cost and improve the efficiency of the process. It also helps to extend the service life of the water-blocking zipper.

The water blocking zipper of the present invention and the manufacturing method thereof can be provided on the surface of the waterproof membrane instead of being covered by the waterproof membrane, so that the waterproof layer and the waterproof membrane have exposed portions, so The choice is to make the two colors or textures different, so that the overall water-repellent zipper has a richer and more beautiful appearance and texture, which helps to enhance consumers' willingness to purchase.

The material of the waterproof layer is preferably the same as the material of the waterproof film to improve the fusion property between the waterproof layer and the waterproof film, so that the waterproof layer is less likely to be peeled off.

The tape has a first surface and a second surface. The waterproof film has a third surface and a fourth surface. The sprocket is coupled to the first surface of the tape. The third surface of the film is bonded to the second surface of the tape, and the waterproof layer is disposed on the fourth surface of the waterproof film; the structure is simple and easy to manufacture, and has the effects of improving manufacturing convenience and efficiency.

Wherein the tape is connected to the first surface and the second surface by an inner side, the inner sides of the two strips of the two chains are opposite, and the inner side of each strip faces the two waterproof layers of the two chains In the range covered by the two, the two waterproof layers of the two chains can jointly provide a good waterproof effect on the two tapes.

Wherein, the waterproof layer can be formed by using a film, a transfer or a screen printing method, so that the waterproof layer exhibits any pattern, and has the effects of improving product identification or texture.
