[0023] like Figure 1-3 As shown, a metal sealed can with convenient buckling includes a can body 10 and an end cover 20 buckled at one end thereof; the central axis of the can body 10 coincides with the end cover 20, and the end cover 20 includes an upper cover 21, an upper sealing cover 22, a lower sealing cover 23 and an inner cover 24 buckled in sequence, wherein:

[0024] The upper cover 21 is a thin-walled structure with one end open, and a first sealing structure 1 is provided on the inner wall of the side wall end of the open end;

[0025] The upper sealing cover 22 is a stepped structure with a larger upper portion and a smaller lower portion. The upper portion thereof is a thin-walled structure and is matched and embedded in the inner side of the first sealing structure 1. The inner wall of the end portion thereof is provided with a second sealing structure 2. The lower portion of the upper sealing cover 22 extends to the outer side of the upper cover 21 and extends in the same direction thereof.

[0026] The lower sealing cover 23 is a stepped structure with a small upper portion and a large lower portion. The upper portion thereof is matched and sleeved on the periphery of the lower portion of the upper sealing cover 22, and the lower portion thereof is provided with a third sealing structure 3, which is matched and sleeved on the periphery of the side wall of the open end of the can body 10;

[0027] The inner cover 24 is a thin-walled structure with one end open. A fourth sealing structure 4 is disposed on the outer wall of the open end. The fourth sealing structure 4 matches and abuts against the open end of the can body 10 and is connected to the third sealing structure 3 .

[0028] When closing the sealed can, first buckle the inner cover 24 on the inner wall of the can body 10, and make the fourth sealing structure 4 on it overlap the end of the can body 10, then buckle the lower sealing cover 23 on the upper end of the inner cover 24 and press the third sealing structure 3 on it on the periphery of the fourth sealing structure 4, then embed the lower part of the upper sealing cover 22 into the upper end of the lower sealing cover 23, and finally buckle the upper cover 21 on the upper outer side of the upper sealing cover 22, and make the first sealing mechanism 1 against the outer wall of the upper sealing cover 22; or first buckle the inner cover 24 on the can body 10, and then buckle the assembled upper cover 21, upper sealing cover 22 and lower sealing cover 23. When opening the sealed can, just grab the upper cover 21 and the upper sealing cover 22, pull the lower sealing cover 23 away from the can body 10, and then take out the inner cover 24, which is convenient to operate.

[0029] The utility model has excellent sealing performance, such as Figure 3 As shown, when the end cover 20 is in a closed state, the first sealing structure 1, the second sealing structure 2, the third sealing structure 3 and the fourth sealing structure 4 respectively seal the connections between the upper cover 21, the upper sealing cover 22, the lower sealing cover 23, the inner cover 24 and the can body 10, thereby isolating most foreign matter such as water vapor and particles from the outside of the can body 10 and the end cover 20.

[0030] Furthermore, the first sealing structure 1 , the second sealing structure 2 , the third sealing structure 3 and the fourth sealing structure 4 are all smooth inwardly rolled structures, and are formed integrally with the upper cover 21 , the upper sealing cover 22 , the lower sealing cover 23 and the lower cover 24 , respectively.

[0031] The utility model adopts an integrally formed sealing mechanism. After the components of the end cover 20 are correctly assembled, they themselves have good sealing performance, and there is no need to use additional functional parts such as sealing rings. It is easy to use and the sealing performance is continuous and stable.

[0032] Further, such as Figure 3 As shown, the lower sealing cover 23 is provided with an avoidance hole groove 5 adapted to the lower part of the upper sealing cover 22, and the depth of the avoidance hole groove 5 is greater than the depth of the lower part of the upper sealing cover 22; an isolation protrusion 6 is also formed on the side wall of the avoidance hole groove 5, and the isolation protrusion 6 is abutted against the lower side wall of the upper sealing cover 22.

[0033] It is understandable that when the end cover 20 is buckled, the upper and lower sealing covers are pressed tightly together, and the deeper avoidance hole groove 5 and the isolation protrusion 6 form a buffer space between the two to avoid the formation of a vacuum between the two and prevent them from being difficult to disassemble.

[0034] Furthermore, the maximum outline dimension of the upper portion of the lower sealing cover 23 is smaller than the maximum outline dimension of the upper portion of the upper sealing cover 22 .

[0035] It is understandable that the relatively small upper portion of the lower sealing cover 23 and the relatively large upper sealing cover 22 can form a manipulation space between the end cover 20 and the can body 10, making it convenient for people to grasp the end cover 20 by hand or tools so as to open or close the end cover 20 and the can body 10.

[0036] Furthermore, a vent hole groove 7 is formed on the upper sealing cover 22 , and the vent hole groove 7 is connected with the avoidance hole groove 5 after being buckled.

[0037] When the end cover 20 (except the inner cover 24) is buckled together, the connected vent slot 7 and the avoidance slot 5 can facilitate the separation of the upper sealing cover 22 and the lower sealing cover 23: when the upper cover 21 or the first sealing structure 1 is opened or loosened, air can enter the avoidance slot 5 through the upper sealing cover 22, thereby facilitating the separation of the upper and lower sealing covers. On the other hand, the provision of the vent slot 7 can also reduce the weight of the upper sealing cover 22, thereby reducing the overall weight of the sealed can and reducing the production cost. During use, the vent slot 7 can also be filled with hygroscopic material to further improve the moisture-proof performance of the sealed can.

[0038] The utility model sets the end cover 20 as a structure composed of an upper cover 21, an upper sealing cover 22, a lower sealing cover 23 and an inner cover 24, and arranges a first sealing structure 1, a second sealing structure 2, a third sealing structure 3 and a fourth sealing structure 4 at the connection points, which can not only prevent foreign matter from entering the can body 10 from the connection points and has good sealing performance, but also leaves a control space formed by the upper and lower sealing covers on the end cover 20, so that it is convenient to buckle or open the end cover 20 with the can body by fingers or tools, and is easy to use.

[0039] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
