Abstract
Description
Technical Field
[0001] The utility model relates to the field of cans, in particular to a can with good sealing performance. Background Art
[0002] A can is a sealable container made of metal sheets, glass, plastic, cardboard, or a combination of these materials. It contains commercial food that has been specifically treated to achieve commercial sterility and can be kept at room temperature for a long time without spoiling. This type of packaged food is called a can. Existing metal cans have poor sealing and protective properties. They are prone to deformation and leakage after being dropped from a height or subjected to external impact or compression, causing the food inside the can to come into contact with air, making the can damaged and inedible. Therefore, there is an urgent need to develop a can with good sealing properties that can prevent deformation and leakage caused by dropping from a height or external impact or compression, and improve the overall sealing effect. Utility Model Content
[0003] In order to overcome the shortcomings of existing metal cans, which have poor sealing and protection, and are prone to deformation and leakage after falling from a height or being subjected to external impact or extrusion, resulting in contact between the food in the can and the air, the technical problem to be solved by the utility model is to provide a can with good sealing performance, which can prevent deformation and leakage caused by falling from a height or being subjected to external impact or extrusion, and improve the overall sealing effect.
[0004] The present invention is achieved by the following specific technical means:
[0005] A can with good sealing performance comprises a cylindrical can body with an opening at one end, a can lid fixedly arranged at the opening of the can body, and a pull ring arranged on the surface of the can lid at one end away from the can body;
[0006] A cylindrical sealed inner tank is provided inside the tank body, and an opening is provided at one end of the sealed inner tank away from the bottom of the tank body; and a protective layer is provided between the sealed inner tank and the tank body; a sealing cover for sealing the sealed inner tank is provided at the opening of the sealed inner tank; the sealing cover includes a cylindrical sheet-like cover body, and a sealing ring is provided on the outer ring of the cover body for buckling with the outer edge of the opening of the sealed inner tank; a lifting column is protruding from the surface of the cover body on the side away from the sealed inner tank.
[0007] Furthermore, the protective layer is made of high-elastic rubber, which has a good elastic buffering effect and prevents external force impact from directly acting on the sealed inner tank.
[0008] Furthermore, the sealing cover is made of a soft plastic sealing cover, which has good flexibility and sealing performance and can achieve a good sealing effect under a relatively low contact pressure.
[0009] Furthermore, the uppermost end of the sealing cover is in contact with the can lid, so that the can lid can exert a certain pressure on the sealing cover, thereby further improving the sealing performance.
[0010] Furthermore, a groove is provided at the joint between the sealing ring and the outer edge of the opening of the sealed inner tank, thereby ensuring the sealing effect between the sealing cover and the outer edge of the opening of the sealed inner tank.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] The utility model has good sealing performance, prevents deformation and leakage caused by falling from a height or being squeezed by external impact, and improves the overall sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the accompanying drawings: Example
[0018] A can with good sealing performance, such as Figure 1-3 As shown, it comprises a cylindrical tank body 1 with an opening at one end, a tank cover 2 is fixedly provided at the opening of the tank body 1; a pull ring 3 is provided on the surface of the end of the tank cover 2 away from the tank body 1;
[0019] A cylindrical sealed inner tank 4 is provided inside the tank body 1, and the sealed inner tank 4 is provided with an opening at one end away from the bottom of the tank body 1; and a protective layer 5 is provided between the sealed inner tank 4 and the tank body 1; a sealing cover 6 for sealing the sealed inner tank 4 is provided at the opening of the sealed inner tank 4; the sealing cover 6 includes a cylindrical sheet-like cover body 61, and a sealing ring 62 is provided at the outer ring of the cover body 61 for buckling with the outer edge of the opening of the sealed inner tank 4; a lifting column 63 is protruding from the surface of the cover body 61 on the side away from the sealed inner tank 4.
[0020] Working principle:
[0021] The utility model can is provided with a sealed inner can 4 inside the can body 1, and a protective layer 5 is provided between the sealed inner can 4 and the can body 1. The protective layer 5 is made of high-elastic rubber and has a good elastic buffering effect. The sealed inner can 4 is protected by the can body 1 and the protective layer 5. When an external impact acts on the external can body 1, the buffering absorption of the protective layer 5 prevents the external impact force from directly acting on the sealed inner can 4, prevents the can body 1 from being deformed and leaking due to the impact and falls, and improves the overall sealing effect of the can.
[0022] At the same time, a sealing cover 6 for sealing the sealed inner tank 4 is provided at the opening of the sealed inner tank 4. The sealing cover 6 is made of soft plastic, has good flexibility and sealing performance, and can achieve a good sealing effect under a lower contact pressure; a sealing ring 62 is provided at the outer ring of the cover body 61 for buckling with the outer edge of the opening of the sealed inner tank 4, and a buckling groove is provided on the sealing ring 62 to ensure the sealing effect between the sealing cover 6 and the outside of the opening of the sealed inner tank 4; and a lifting column 63 is protruding from the surface of the cover body 61 on the side away from the sealed inner tank 4 to facilitate the user to open the sealing cover 6.
[0023] While the present disclosure has been described in detail with reference to exemplary embodiments, the present disclosure is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of the present disclosure.
