[0021] The following specifically describes an antibacterial and mildew-proof sealing bag according to an embodiment of the present utility model with reference to the drawings.
[0022] Embodiment
[0023] For ease of understanding, please refer to Figures 1 to 4, An embodiment of an antibacterial and mildew-proof seal bag provided by the present utility model includes a seal bag body 1. An enhanced bag head 2 is fixedly connected to the opening end of the seal bag body 1, and a sealing assembly 3 is provided on the inner wall of the enhanced bag head 2;
[0024] The sealing assembly 3 includes a sealing strip 31 and a sealing slot member 32. The sealing strip 31 is fixedly connected to one inner wall of the enhanced bag head 2, and the sealing slot member 32 is fixedly connected to the other inner wall of the enhanced bag head 2. A magnet strip 311 is provided inside the sealing strip 31, an iron sheet 322 is provided inside the sealing slot member 32, and a sealing layer 321 is fixedly connected to the inner wall of the sealing slot member 32.
[0025] It should be noted that the seal bag body 1 is preferably made of materials such as high-density polyethylene (HDPE) or polyethylene terephthalate (PET) suitable for food-grade packaging, and has good transparency and mechanical strength. The enhanced bag head 2 is used to enhance the structural strength of the sealing opening, ensuring stability during the sealing process and firmness after sealing. The enhanced bag head 2 is made of a material with increased thickness to withstand the pressure during the sealing operation. The sealing strip 31 is fixed to one inner wall of the enhanced bag head 2, and the sealing slot member 32 is fixed to the opposite inner wall. While they are sealed by mutual clamping, they also achieve rapid and tight closure through the magnetic attraction between the magnet strip 311 and the iron sheet 322.
[0026] Furthermore, the sealing layer 321 provided on the inner wall of the sealing slot member 32 is preferably a thermoplastic elastomer (TPE) to further enhance the sealing effect.
[0027] In an alternative embodiment: An arc-shaped protrusion 323 is fixedly connected to the inner wall of the sealing slot member 32, and when the sealing strip 31 is clamped and sealed with the sealing slot member 32, the side wall of the sealing strip 31 corresponding to the arc-shaped protrusion 323 has a matching sealing groove.
[0028] It should be noted that the arc-shaped protrusion 323 is provided on the inner wall of the sealing slot member and is matched with the sealing groove on the sealing strip, forming an additional sealing point during closure and increasing the reliability of the seal.
[0029] In an alternative embodiment: An antibacterial and mildew-proof layer is laid on the inner wall of the seal bag body 1.
[0030] It should be noted that the antibacterial and mildew-proof layer is laid on the inner wall of the seal bag body 1, and is preferably a silver ion coating, a polymer film impregnated with an antibacterial agent, or other known antibacterial and mildew-proof materials to prevent the growth of bacteria and mold.
[0031] In an alternative embodiment: The magnet strip 311 includes a plurality of magnet blocks 3111 and a plurality of flexible connectors 3112, and the flexible connectors 3112 are fixedly connected between two adjacent magnet blocks 3111.
[0032] It should be noted that the magnet strip 311 is composed of a plurality of magnet blocks 3111 and flexible connectors 3112. The magnet blocks can ensure sufficient magnetic force to attract the iron sheet, while the flexible connectors allow the whole magnet strip to be bent and deformed, which is convenient for use.
[0033] In an alternative embodiment: The position of the arc-shaped protrusion 323 is located between the magnet strip 311 and the iron sheet 322.
[0034] It should be noted that by arranging the arc-shaped protrusion 323 between the magnet strip 311 and the iron sheet 322, it is convenient to ensure the sealing effect of the arc-shaped protrusion 323 under the adsorption of magnetic attraction.
[0035] In an alternative embodiment: A plurality of reinforcing rib strips are fixedly connected to the inner wall of the reinforcing bag head 2.
[0036] It should be noted that the reinforcing rib strips are fixedly connected to the inner wall of the reinforcing bag head 2, and these reinforcing rib strips help to improve the structural rigidity of the sealing area.
[0037] Among them, the manufacturing process is as follows:
[0038] The sealing bag body 1 is produced by using blow molding or extrusion molding technology. The reinforcing bag head 2 is manufactured by injection molding or die pressing process and fixed to the opening end of the bag body. The sealing strips 31 and the sealing groove parts 32 are respectively installed on the inner walls on both sides of the reinforcing bag head. The magnet strip 311 and the iron sheet 322 are embedded into the corresponding components, and the correct layout of the magnet blocks 3111 and the flexible connectors 3112 is ensured. The sealing layer 321 and the arc-shaped protrusion 323 are coated or pasted on the inner wall of the sealing groove part 32. The antibacterial and mildew-proof layer is covered on the inner wall of the sealing bag body by using spraying or dipping technology.
[0039] Working principle: During use, the magnet blocks 3111 in the magnet strip 311 and the iron sheets 322 in the sealing card slot member 32 attract each other to form a magnetic seal, ensuring close contact between the sealing strip 31 and the sealing card slot member 32. When the sealing strip 31 is docked with the sealing card slot member 32, the arc-shaped protrusion 323 precisely matches the sealing groove on the sealing strip 31, further enhancing the sealing effect and preventing the penetration of air and moisture. The sealing layer 321 inside the sealing card slot member 32 provides additional sealing protection to ensure that the sealed bag can maintain good airtightness and waterproofness even in harsh environments. The antibacterial and mildew-proof layer laid on the inner wall of the sealed bag body 1 destroys the cell structure of microorganisms, inhibits their metabolism, and prevents the growth and reproduction of bacteria and molds through the action of silver ions, quaternary ammonium salts, photocatalysts, nanomaterials, or other antibacterial agents. Moreover, the antibacterial agent in the antibacterial and mildew-proof layer can be continuously released to form an environment that inhibits the growth of microorganisms, thereby protecting the items in the bag from contamination in the long term.
[0040] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
