Description

Technical Field

[0001] The utility model belongs to the technical field of zippers, and in particular relates to an environmentally friendly zipper. Background Art

[0002] The zipper is a common daily necessity, usually used to connect two or more items, such as clothing, bags, etc. It consists of multiple chain teeth and a pull head, which can be easily opened and closed.

[0003] Most of the existing zippers are made of plastic, but plastic materials themselves are not easy to degrade and are relatively difficult to recycle. This means that once plastic zippers become waste, they are difficult to decompose in the natural environment, causing long-term pollution to the environment. At the same time, due to the limitations of the recycling system and the lack of technology, the recycling rate of plastic zippers is also relatively low, further exacerbating the pollution to the environment. Utility Model Content

[0004] The utility model discloses an environmentally friendly zipper, which mainly solves the problem that the current zipper uses plastic as material, thus causing environmental pollution.

[0005] Preferably, the chain belt is provided with a plurality of chain teeth, and the chain teeth on the two chain belts can be staggered and meshed with each other to combine the two chain belts.

[0006] Preferably, the chain belt includes a first chain belt and a second chain belt.

[0007] Preferably, the sprockets include first sprockets arranged on the first chain belt and second sprockets arranged on the second chain belt.

[0008] Preferably, the chain belt further comprises a belt body, the chain teeth are fixedly connected to the belt body, the upper and lower surfaces of the belt body are both provided with waterproof materials, and a waterproof and breathable layer is provided in the middle of the belt body.

[0009] Preferably, the waterproof material is one of PVC, PUR and TPU.

[0010] Preferably, the material of the chain belt and the chain teeth is PLA.

[0011] Preferably, the zipper unit includes a zipper head, and the surfaces of the zipper head and the chain teeth are covered with a protective film.

[0012] Preferably, the material of the protective film is water-based polyurethane or PLA.

[0013] The technical solution provided by the utility model has at least the following technical effects:

[0014] The utility model adopts PLA material to make the zipper teeth and chain belt, because the source of PLA is plant starch, which is a matrix material with a wide range of resources. Under the circumstances of high crude oil prices and depleted oil reserves, the use of PLA material to make zippers has obvious social benefits and helps promote the green development of the zipper industry.

[0015] The utility model lays a layer of wear-resistant, corrosion-resistant and scratch-resistant protective film on the surface of the zipper head and the chain teeth, thereby protecting them from factors such as wear, friction, chemical corrosion and external scratches in daily use, thereby greatly increasing the service life of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention.

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0020] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0022] Please refer to Figure 1 The utility model provides an environmentally friendly zipper, including two chain belts and a clip chain unit, the chain belts are provided with a plurality of chain teeth, the chain teeth on the two chain belts can be staggered and meshed with each other to combine the two chain belts, the chain belts include a first chain belt 2 and a second chain belt 3, the chain teeth include a first chain tooth 4 arranged on the first chain belt 2 and a second chain tooth 5 arranged on the second chain belt 3, the chain belt also includes a belt body, the chain teeth are fixedly connected to the belt body, the upper and lower surfaces of the belt body are provided with waterproof materials, and the middle of the belt body is provided with a waterproof and breathable layer, the material of the chain belt and the chain teeth is PLA, the clip chain unit includes a zipper head, and the surface of the zipper head and the chain teeth is paved with a protective film. In this embodiment, the material of the protective film is water-based polyurethane, which has excellent wear resistance, elasticity and weather resistance.

[0023] In this embodiment, the waterproof material is TPU, and the material of the chain belt and the chain teeth is PLA. PLA is a biodegradable material made from starch raw materials extracted from renewable plant resources. PLA is biocompatible and biodegradable, which means that it can be completely decomposed by microorganisms in the natural environment to generate carbon dioxide and water without polluting the environment. Using PLA materials to make zippers helps reduce dependence on petroleum resources, because PLA is derived from plant starch, a matrix material with a wide range of resources. With high crude oil prices and depleted oil reserves, using PLA materials to make zippers has obvious social benefits.

[0024] The utility model adopts PLA material to make the zipper teeth and chain belt, because the source of PLA is plant starch, which is a matrix material with a wide range of resources. Under the circumstances of high crude oil prices and depleted oil reserves, the use of PLA material to make zippers has obvious social benefits and helps promote the green development of the zipper industry.
