Description

Technical Field

[0001] This application relates to the technical field of metal cans, and specifically to a sealing structure for a metal can body. Background Art

[0002] A metal can is a common packaging container, usually made of metal materials, with good sealing performance, strength and corrosion resistance. Common materials for metal cans include aluminum, tinplate (tin-coated steel sheet) and stainless steel, etc.

[0003] Metal cans are commonly used for packaging food (such as canned food, beverages), chemical products (such as paints, aerosols), etc. According to different uses and shapes, there are various types of metal cans, such as cylindrical cans, square cans, special-shaped cans, etc.

[0004] For example, the patent with the publication number CN208291714U specifically discloses a metal can that can cool down, including the settings of a metal can body, a can bottom, a tin coating, a heat insulation layer, and an adhesive layer, so that the food can be stored for a long time and is not easily spoiled. The printing layer on the outer surface of the metal makes the beautiful patterns attract the attention of consumers and enhances the consumers' desire to purchase.

[0005] When the above-mentioned patented metal can is in use, since the can mouth of the metal can is exposed, dust and dirt are likely to adhere to the can mouth position during the transportation of the metal can. Therefore, when people open it for drinking, they need to clean the can mouth. At the same time, after the metal can is opened by pulling the pull ring and then drunk, it is difficult to reseal, so that the beverages or foods in the metal can are easily spoiled. Therefore, it is necessary to design a sealing structure for a metal can body to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0007] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide a sealing structure for a metal can body to solve the problems that when the above-mentioned patented metal can is in use, since the can mouth of the metal can is exposed, dust and dirt are likely to adhere to the can mouth position during the transportation of the metal can, so that when people open it for drinking, they need to clean the can mouth. At the same time, after the metal can is opened by pulling the pull ring and then drunk, it is difficult to reseal, so that the beverages or foods in the metal can are easily spoiled.

[0008] The technical solution adopted by this application to solve its technical problems is: a sealing structure for a metal tank body. It mainly includes: a metal tank body; a tank cover assembly, which is installed on the metal tank body. The tank cover assembly has a top cover for sealing the metal tank body, and the top cover has a drinking port: a first pull ring, which is installed on the top cover; a sealing assembly, which is installed on the top cover. The sealing assembly includes: a transparent cover, which covers the top cover; two groups of pull rods, which are movably inserted through the transparent cover. One end of the two groups of pull rods is connected with a sealing plug; a spring, which is sleeved on the pull rod; a holding cover, which is connected to the other ends of the two groups of pull rods.

[0009] Further, a second pull ring is installed on the holding cover.

[0010] Further, an auxiliary ring is installed on the first pull ring.

[0011] Further, a tank support assembly is sleeved on the metal tank body. The tank support assembly includes a tank support body sleeved at the bottom end of the metal tank body, and the tank support body includes a bottom support plate.

[0012] Further, a plurality of side slots are opened on the tank support body.

[0013] The beneficial effect of this application is: a sealing structure for a metal tank body provided by this application can prevent dust at the tank opening of the metal tank body through the settings of the auxiliary ring, transparent cover, pull rod, spring, sealing plug, holding cover and second pull ring, and at the same time is convenient for sealing and storing the metal tank body that has not been completely consumed.
