Technical Field

[0001] The utility model relates to the technical field of inflatable membranes, and more specifically, to a shockproof inflatable membrane for an express box. Background Art

[0002] Express delivery has become a common way for people to transport daily items, and the types of items transported by express delivery are diverse. For different transported items, in order to ensure the safety of the items, it is generally necessary to use a packaging machine to wrap the express items with an outer film.

[0003] The existing inflatable protective film is easily damaged and leaks during use, thereby losing its protective effect on the article.

[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a shock-proof inflatable membrane for an express box.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a shockproof inflatable film for an express box, comprising an intermediate layer, wherein the upper and lower surfaces of the intermediate layer are both provided with sealing films, the peripheral sides of the two sealing films are fixedly connected to the surface of the intermediate layer, an inflation cavity is formed between the sealing film and the intermediate layer, and an inflation valve is provided on the sealing film.

[0007] By adopting the above technical solution, by arranging sealing films on both side surfaces of the middle layer, thereby forming two air-filled cavities, the cushioning effect and the protective effect can be further improved. During use, when the sealing film on one side is damaged and leaks, the air-filled cavity on the other side can still play a protective and cushioning role, thereby improving its use effect.

[0008] The present invention is further configured as follows: the middle layer is configured in a rectangular shape, and connecting pieces are provided on the four sides thereof.

[0009] The present invention is further configured as follows: the intermediate layer includes two intermediate films having a surface area larger than that of the sealing film; the two intermediate films are fixedly connected on the peripheral sides of the sealing film by adhesive; the connecting piece includes magnetic strips arranged on the opposite surfaces of the peripheral sides of the two intermediate films; the two magnetic strips attract each other and fix the peripheral sides of the two intermediate films.

[0010] The utility model is further configured as follows: a reinforcement layer is provided between the two intermediate films, the reinforcement layer includes two reinforcement cloths provided on the opposite surfaces of the two intermediate films by means of viscose, the two reinforcement cloths are located on the surface of the inflation cavity and are fixedly connected by means of viscose, and the two magnetic strips are fixedly connected to the opposite surfaces of the peripheral sides of the two reinforcement cloths by means of viscose.

[0011] The utility model is further configured as follows: protective cloths are provided on the surfaces of the two sealing films, and the protective cloths are fixed to the surfaces of the sealing films and the peripheral sides of the intermediate film by adhesive.

[0012] The utility model is further configured as follows: the reinforcing cloth and the protective cloth are both made of polyester fabrics.

[0013] The utility model has the following beneficial effects: by arranging sealing films on both side surfaces of the middle layer, two air-filled cavities are formed, which can further enhance the cushioning effect and the protective effect; and during use, when the sealing film on one side is damaged and leaks, the air-filled cavity on the other side can still play a protective and cushioning role, thereby enhancing its use effect.

[0017] The present invention will be described in further detail below with reference to the accompanying drawings.

[0018] Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0019] As shown in the figure, a shockproof inflatable film for an express box includes an intermediate layer. Sealing films 1 are provided on the upper and lower surfaces of the intermediate layer. The peripheral sides of the two sealing films 1 are fixedly connected to the surface of the intermediate layer. An inflation cavity 2 is formed between the sealing film 1 and the intermediate layer. An inflation valve 3 connected to the inflation cavity 2 is provided on the sealing film 1.

[0020] By arranging sealing films 1 on both side surfaces of the middle layer, two air-filled cavities 2 are formed, which can further enhance the cushioning effect and the protective effect. When in use, when the sealing film 1 on one side is damaged and leaks, the air-filled cavity 2 on the other side can still play a protective and cushioning role, thereby enhancing its use effect.

[0021] The middle layer is rectangular and has connectors on its four sides. When in use, the inflatable membrane can be matched and combined through the connectors according to different usage environments to form combined inflatable membranes of different shapes and sizes to improve its scope of application.

[0022] The middle layer comprises two intermediate films 4, each with a larger surface area than the inflatable cavity 2. These two films 4 are securely connected to the periphery of the sealing film 1 via adhesive. The connectors include magnetic strips 5 disposed on the opposing peripheries of the two intermediate films 4. The two magnetic strips 5 attract each other and secure the peripheries of the two intermediate films 4. By cross-linking the peripheries of the intermediate layers of the two inflatable films and then magnetically securing them with the magnetic strips 5, the two inflatable films can be quickly and easily connected and removed, making them convenient for use.

[0023] A reinforcement layer is provided between the two intermediate films 4. This layer consists of two pieces of reinforcing cloth 6, attached to opposing surfaces of the two intermediate films 4 with adhesive. The surfaces of the two reinforcing cloths 6 between the plenum chambers 2 are securely connected with adhesive. Two magnetic strips 5 are also securely attached to the opposing surfaces of the reinforcing cloths 6 with adhesive. Protective cloth 7 is also provided on the surfaces of both sealing films 1, secured to the surrounding surfaces of the sealing films 1 and the intermediate films 4 with adhesive. Both the reinforcing cloths 6 and 7 are made of polyester.

[0024] The reinforcing cloth 6 can effectively improve the structural strength of the inflatable membrane and reduce the damage caused by external forces. The protective cloth 7 can protect the sealing membrane 1 to reduce the occurrence of air leakage, increase its service life, and enable reuse.

[0025] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
