Description

Technical Field

[0001] This utility model belongs to the field of zipper technology, and in particular relates to an invisible zipper. Background Technology

[0002] Zippers are a very common clothing accessory, a type of chain used for connecting and separating items. They are commonly found in various garments, bags, tents, cushions, car seat cushions, sofa cushions, and other products. During the production process, manufacturers often choose to use invisible zippers to hide the chain teeth for aesthetic purposes. However, traditional invisible zippers often deform due to excessive force or prolonged use, and cannot return to their original shape on their own, resulting in exposed chain teeth. This not only greatly reduces the aesthetics of clothing, tents, cushions, car seat cushions, and sofa cushions, but also easily causes the chain teeth to get stuck when they come into contact with hair or other foreign objects. Utility Model Content

[0003] This utility model discloses an invisible zipper, which mainly solves the problems of traditional zippers being unsightly and prone to getting stuck.

[0004] To achieve the aforementioned objective, this utility model provides an invisible zipper, comprising a chain belt and a zipper pull. The chain belt includes zipper teeth and a fabric strip. One end of the fabric strip is provided with a connecting portion, and the fabric strip is fixedly connected to the zipper teeth through the connecting portion. An elastic element is provided at the connecting portion.

[0005] Preferably, the surface of the zipper tooth is provided with a protective coating.

[0006] Preferably, the elastic element is made of polylactic acid (PLA).

[0007] Preferably, the fabric strip has connecting edges on both sides.

[0008] Preferably, the connecting part is fixedly connected to the zipper rack via stitching.

[0009] Preferably, the zipper teeth are made of polyester or nylon, and the fabric strip is made of polyester or nylon.

[0010] The technical solution provided by this utility model has at least the following technical effects:

[0011] This invention, by setting an elastic element at the connection part of the zipper, allows the zipper to quickly return to its original position each time it is pulled open due to the elastic force of the elastic element, thereby achieving the effect of hiding the chain teeth. This is both aesthetically pleasing and prevents the zipper from getting stuck due to foreign objects. Attached Figure Description

[0021] According to an embodiment of the present invention

[0022] Please refer to Figure 1-3 This utility model provides an invisible zipper, including a chain strap 1 and a zipper pull 4. The chain strap 1 includes zipper teeth 7 and a fabric strip. One end of the fabric strip is provided with a connecting part, and the fabric strip is fixedly connected to the zipper teeth 7 through the connecting part. An elastic element 6 is provided at the connecting part. The surface of the zipper teeth 7 is provided with a protective coating. The elastic element 6 is made of polylactic acid (PLA). PLA has excellent high tensile strength, high tensile strength, toughness and aging resistance. It is a new type of biodegradable and environmentally friendly material that can ensure the service life and rebound effect of the zipper. Other common materials on the market, such as TPU, can also be used, and it is not limited to these. Connecting edges are provided on both sides of the fabric strip, and the connecting part is fixedly connected to the zipper teeth 7 by stitching. In this embodiment of the utility model, the zipper teeth 7 is made of polyester, and the fabric strip is made of nylon. Common materials on the market, such as plastic and resin, can also be used instead, and it is not limited to these.

[0023] In use, the two ends of the zipper are first fixed in the required position by the connecting piece 2. At this time, the zipper seam 3 will be tightly closed due to the elastic force of the elastic element 6 of the connecting part, so that the zipper is hidden.

[0024] According to another embodiment of the present invention

[0025] Please refer to Figure 4 The elastic element 6 is provided with a through hole 9, which can enhance the overall breathability of the zipper and thus improve the user experience of the product.

[0026] This invention, by setting an elastic element 6 at the connection part of the chain belt 1, allows the chain belt 1 on both sides to quickly spring back to its original position each time the zipper is pulled open due to the elastic force of the elastic element 6, thereby achieving the effect of hiding the chain teeth. This is both aesthetically pleasing and prevents the problem of foreign objects getting stuck.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
