[0028] like Figures 1 to 5 As shown, an embodiment of the utility model provides a packaging can, including a can body 100 and an upper cover 200 . Specifically, the can body 100 includes a can neck 110 , a can shoulder 120 and a can body 130 .

[0029] The inner side wall of the tank neck 110 is provided with a limiting portion 111 protruding outward and tilted upward, and a plurality of limiting portions 111 are axially symmetrically arranged around the tank neck 110 .

[0030] Furthermore, the upper end of the tank neck 110 is bent inwardly to form a first curved wall 114 , and the upper peripheral edge of the upper cover 200 is recessed inwardly to form a second curved wall 230 corresponding to the first curved wall 114 .

[0031] Furthermore, the lower peripheral edge of the upper cover 200 is bent inward to form a connecting wall 210 that abuts against the inner side wall of the upper cover 200 . The connecting wall 210 can enhance the stability of the side wall structure of the upper cover 200 .

[0032] Furthermore, the connecting wall 210 is provided with a matching portion 220 that matches with the limiting portion 111. Specifically, the matching portion 220 has the same structure as the limiting portion 111. When the user rotates the upper cover 200, specifically, the matching portion 220 can be limited to the lower end of the limiting portion 111. Specifically, the matching portion 220 moves downward from the upper end of the limiting portion 111 and the downward wall surface along the path of the limiting portion 111 to squeeze the limiting portion 111 until it is tightly attached to the limiting portion 111, so that the upper cover 200 can be limited to the tank neck 110, that is, the upper cover 200 is closed; or the matching portion 220 is disconnected from the limiting portion 111, so that the upper cover 200 is disconnected from the tank neck 110, that is, the upper cover 200 is opened.

[0033] It should be understood that the cooperation between the limit portion 111 and the matching portion 220 can prevent the internal part of the can body 100 from rebounding due to air pressure or material stress, thereby affecting the sealing performance. It should be noted that rotating the upper cover 200 clockwise is an opening operation, and rotating the upper cover 200 counterclockwise is a closing operation. Of course, the opposite operation can also be performed according to design requirements.

[0034] Furthermore, when the upper cover 200 is limited to the tank neck 110, the first curved wall 114 and the second curved wall 230 are in close contact with each other, thereby achieving the purpose of sealing. The overall structure is simple and easy to operate, which can greatly improve the user experience, facilitate production, and reduce production costs.

[0035] It should be understood that during production, the staff first forms the matching portion 220 by denting the side wall of the upper cover 200, and then bends the side wall of the upper cover 200 to form the connecting wall 210 to facilitate production.

[0036] In one embodiment, the can body 100 further includes a can shoulder 120. When the upper cover 200 is limited to the can neck 110, the lower end of the upper cover 200 abuts against the can shoulder 120, further improving the sealing performance and the stability of the upper cover 200 after closing.

[0037] In one embodiment, the tank shoulder 120 is tilted downward and bent inward, so as to improve the stability of the structure at the tank shoulder 120 and effectively prevent deformation of the structure there. It should be understood that the lower periphery of the upper cover 200 abuts against the upper end of the tank shoulder 120.

[0038] In one embodiment, the lower end of the tank shoulder 120 is provided with an outwardly curved reinforcing wall 121 , and the upper end of the tank body 130 is connected to the lower end of the reinforcing wall 121 , so as to further improve the stability of the tank shoulder 120 .

[0039] In one embodiment, the can body 130 is rectangular, and the four corners of the can body 130 are recessed inward to form a recessed portion 131 to improve the stability of the can body 130 and effectively avoid the problem of structural deformation affecting the use.

[0040] In one embodiment, the first curved wall 114 extends inwardly from one end of the can neck 110 to form a first horizontal wall 112. It should be understood that the first horizontal wall 112 forms the can mouth, and for further sealing, aluminum foil will be pasted on the first horizontal wall 112 to close the can mouth.

[0041] Furthermore, the first horizontal wall 112 is bent downward and extends along the tank neck 110 to form a second horizontal wall 113 abutting against the lower end of the first horizontal wall 112, so as to improve the stability of the structure at the tank mouth and avoid problems such as scratching hands.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
