Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a high-temperature boiling-resistant zipper. Background Art

[0002] A retort bag is a composite plastic film bag that can be heated. It has the advantages of both canned containers and boiling water-resistant plastic bags. Therefore, it is also called a "soft can". In order to avoid leakage of food inside the retort bag during use, a sealed zipper is set at the opening.

[0003] The zipper on the cooking bag has a sliding part that can pull the two rows of teeth into the interlocking position to close the opening. Since the softening temperature of the plastic itself is low, it is easy to soften in high temperature scenes and become unusable. After the softened zipper is pulled up, there are usually gaps between the teeth, which greatly reduces the overall thermal insulation effect and makes it easy for heat to enter from the gap. In view of this, we proposed a high-temperature resistant cooking zipper. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a high temperature cooking resistant zipper which can solve the problem that gaps usually exist between teeth after the zipper is pulled up, thereby greatly reducing the overall thermal insulation effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-temperature resistant cooking zipper, comprising a first chain cloth and a second chain cloth, wherein the first chain cloth and the second chain cloth are respectively provided with first chain teeth and second chain teeth on the surface of the side close to each other, and the first chain teeth and the second chain teeth are provided with grooves for installation on the surface of the side opposite to each other, the first chain teeth and the second chain teeth are both arranged in a cross shape, the lower surface of the first chain teeth is arranged in an inclined shape, and the upper surface of the second chain teeth is arranged in an inclined shape, a zipper socket is fixedly connected to the surface of the second chain cloth on the side close to the first chain cloth, and a plug is fixedly connected to the right surface of the first chain cloth.

[0006] Preferably, a zipper head is slidably connected to the outer surfaces of the first link teeth and the second link teeth.

[0007] Preferably, a pull tab is provided on the zipper head.

[0008] Preferably, a buckle column is fixedly connected to the upper surface of the groove, and a buckle cylinder is fixedly connected to the lower surface of the groove.

[0009] Preferably, a conical positioning groove is provided on the upper surface of the buckle tube.

[0010] Preferably, the first chain cloth and the second chain cloth are both composed of a surface layer, a flame retardant layer and a fiber layer.

[0011] Preferably, the surface layer is arranged on the upper surface of the flame retardant layer, and the fiber layer is arranged on the lower surface of the flame retardant layer.

[0012] Preferably, the outer surfaces of the first coupling teeth and the second coupling teeth are provided with a wear-resistant layer.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) When the high-temperature cooking zipper is zipped up, the plug is inserted into the inside of the zipper socket so that the first chain teeth are in contact with the second chain teeth, and then the zipper head is used to close the zipper. During the closing process, the inclined shape of the lower surface of the first chain teeth and the inclined shape of the second chain teeth can make the upper and lower teeth staggered during the closing process, thereby facilitating the cross-shaped insertion. Through the above structure, the cross-shaped structure can be used to be inserted into each other and not easily pulled apart by external force, while avoiding the appearance of gaps. At the same time, the zipper of the cooking bag adopts a snap-on method, which is quite different from the traditional plastic zipper, thereby improving the high temperature resistance of the zipper when in use, and improving the stability of the zipper when in use, thereby improving the overall practicality of the zipper, and the inclined surfaces of the first chain teeth and the second chain teeth are also convenient for closing.

[0015] (2) When installing the first and second chain teeth of the high-temperature cooking-resistant zipper, the buckle column is pressed into the interior of the buckle tube, and the buckle tube is slightly deformed by pressure to increase the friction between the two. Through the above structure, not only can the buckle column and the buckle tube be used for convenient installation, but the conical positioning groove can also be used to provide a certain positioning when pressing, and the wear-resistant layer can be used to improve the overall wear resistance of the first and second chain teeth, thereby increasing the service life.

[0024] See also Figure 1-5 The utility model provides a technical solution: a high temperature cooking resistant zipper, comprising a first chain cloth 1 and a second chain cloth 2, a first chain tooth 3 and a second chain tooth 4 are respectively arranged on the surface of the first chain cloth 1 and the second chain cloth 2 on one side thereof, a groove 5 for installation is opened on the surface of the first chain tooth 3 and the second chain tooth 4 on the opposite side thereof, the first chain tooth 3 and the second chain tooth 4 are both arranged in a cross shape, the lower surface of the first chain tooth 3 is arranged in an inclined shape, the upper surface of the second chain tooth 4 is arranged in an inclined shape, a zipper socket 6 is fixedly connected to the surface of the second chain cloth 2 on one side thereof close to the first chain cloth 1, a plug 7 is fixedly connected to the right surface of the first chain cloth 1, when the zipper is closed, the first chain tooth 3 and the second chain tooth 4 are arranged in a cross shape, the lower surface of the first chain tooth 3 is arranged in an inclined shape, the upper surface of the second chain tooth 4 is arranged in an inclined shape, a zipper socket 6 is fixedly connected to the surface of the second chain cloth 2 on one side thereof close to the first chain cloth 1, and a plug 7 is fixedly connected to the right surface of the first chain cloth 1, The plug 7 is inserted into the interior of the zipper socket 6, so that the first chain tooth 3 contacts the second chain tooth 4, and then the zipper head 8 is used to pull the zipper together. During the pulling process, the inclined shape of the lower surface of the first chain tooth 3 and the inclined shape of the second chain tooth 4 can make the upper and lower teeth appear staggered during the pulling process, which is convenient for cross-shaped insertion. Through the above structure, the cross-shaped structure can be used to prevent each other from being stuck and not easily pulled apart by external force, while avoiding the appearance of gaps, thereby improving the stability during use and reducing the possibility of high temperature passing through the zipper gap, thereby improving the overall practicality of the zipper, and the inclined surfaces of the first chain tooth 3 and the second chain tooth 4 are also convenient for pulling.

[0025] Furthermore, the outer surfaces of the first chain teeth 3 and the second chain teeth 4 are slidably connected with a zipper head 8, a pull tab is provided on the zipper head 8, a buckle column 9 is fixedly connected to the upper surface of the groove 5, a buckle cylinder 10 is fixedly connected to the lower surface of the groove 5, a conical positioning groove 11 is provided on the upper surface of the buckle cylinder 10, the first chain cloth 1 and the second chain cloth 2 are both composed of a surface layer 12, a flame retardant layer 13, and a fiber layer 14, the surface layer 12 is arranged on the upper surface of the flame retardant layer 13, the fiber layer 14 is arranged on the lower surface of the flame retardant layer 13, the first chain teeth 3 The outer surface of the second chain element 4 is provided with a wear-resistant layer 15. The flame-retardant layer 13 is made of asbestos. Its unique physical and chemical properties enable the first chain cloth 1 and the second chain cloth 2 to have high heat resistance and are not easy to melt and burn. At the same time, due to its filamentary structure, the first chain cloth 1 and the second chain cloth 2 can also have high tensile strength and flexibility, and can form fine fiber filaments. These filamentary fibers can block the spread of flames and heat. At the same time, since asbestos is an inorganic substance, it will not be burned by flames. Instead, a small amount of water vapor is released at high temperature, and a layer of protective asbestos ash is formed to prevent the flame from spreading further. The first chain tooth 3 and the second chain tooth 4 are both made of flame-retardant polyester slices, so that the first chain tooth 3 and the second chain tooth 4 have high high temperature resistance, can maintain stable physical and chemical properties at high temperature, and are not easy to burn or drip. At the same time, the wear-resistant layer 15 is made of chrome-plated coating, so that the first chain tooth 3 and the second chain tooth 4 have high hardness and corrosion resistance, and can give its surface a good gloss to increase the aesthetics. When installing the first chain tooth 3 and the second chain tooth 4, the buckle column 9 is pressed into the inside of the buckle cylinder 10, and the buckle cylinder 10 is slightly deformed by pressure to increase the friction between the two. Through the above structure, not only can the buckle column 9 and the buckle cylinder 10 be used for convenient installation, but also the conical positioning groove 11 can be used to provide a certain positioning when pressing, and the wear-resistant layer 15 can be used to improve the overall wear resistance of the first chain tooth 3 and the second chain tooth 4 and thus increase the service life.

[0026] Working principle: When installing the first chain tooth 3 and the second chain tooth 4, press the buckle column 9 into the inside of the buckle tube 10, and use the pressure to make the buckle tube 10 slightly deform to increase the friction between the two. When zipping up the zipper, insert the plug 7 into the inside of the zipper socket 6 so that the first chain tooth 3 and the second chain tooth 4 are in contact, and then use the subsequent zipper head 8 to pull them together. During the pulling and closing process, the inclined shape of the lower surface of the first chain tooth 3 and the inclined shape of the second chain tooth 4 can make the upper and lower interlacing appear during the pulling and closing process, thereby facilitating the engagement of the cross-shaped structure.

[0027] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
