[0002] A food can is a sealed container used to preserve and store food, usually made of metal, glass or plastic. As a form of food packaging, the primary purpose of a food can is to preserve food, maintain food quality, and extend the storage period. By using sealed packaging containers, food processing, storage, transportation, and sales can be carried out in an industrialized manner.

[0003] There are many types of food cans. For example, Chinese patent CN214931382U discloses a food can for storing dry goods, including a can and other structures. The food can solves the problem of existing food cans for storing dry goods, that is, the dry goods will drop residues, and the residues will cover the dry goods during transportation, thus affecting the use. However, the existing food cans still have the problem of inconvenient sealing, because the traditional food cans will affect the sealing after opening, and when they are closed and opened again, the sealing ability will be seriously reduced, and it is not convenient to seal again, which seriously affects the sealing effect. Therefore, a food can sealing structure is proposed to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2The utility model provides the following technical solutions: a food can sealing structure, including a can body 1, the top cover of the can body 1 is connected to an outer cover 3, a sealing stopper is provided at the lower edge of the outer cover 3, and the sealing stopper is located inside the can body 1, the sealing stopper and the outer cover 3 are integrally formed, and a gap is formed at the side opposite to the sealing stopper and the can body 1, the inner part of the outer cover 3 is movably connected to an inner cover 2, and a sealing ring 5 is provided on one side of the inner cover 2, and the sealing ring 5 is adapted to the gap.

[0021] It should be noted that, in the above embodiment, the gap between the sealing stopper and the tank body 1 is just adapted to the sealing ring 5, so that the sealing ring 5 can flexibly enter the gap to block and seal.

[0022] It should also be noted that in the above embodiment, the sealing ring 5 is an elastic structure, made of rubber, and therefore has a deformable property and can perform a good sealing process.

[0023] In addition, a spring 4 is provided on the outer side of the inner cover 2 , one side of the spring 4 is connected to the outer cover 3 , and a flip buckle 6 is provided on one side of the inner cover 2 .

[0024] Among them, the inner cover 2 is composed of a bottom cover and a lifting column. The top of the outer cover 3 is movably connected to the lifting column with one end passing through the outer cover 3 and extending to the inside of the tank body 1. The bottom of the lifting column is fixedly connected to the bottom cover. An axial hole is opened on one side of the lifting column, and a pin is provided on the flip buckle. The flip buckle 6 is rotatably connected to the lifting column through the pin and the axial hole.

[0025] In the above embodiment, the outer cover 3 is mainly used for covering function, while the inner cover 2 cooperates with the outer cover 3 and the spring 4 to perform flexible sealing adjustment.

[0026] It should also be noted that in addition to relying on spring flip buckles for sealing, the operating method in the above embodiment can also use a variety of methods to lift and seal, such as using a lifting column with a cam groove in combination with a knob to lift and seal.

[0027] In addition, the sealing ring 5 is arranged around the bottom cover, and the outer side of the bottom cover is provided with a mounting groove adapted to the sealing ring 5 .

[0028] The left and right sides of the upper surface of the outer cover 3 are both provided with placement grooves, which are matched with the flip buckles 6 .

[0029] It can be understood that, since the placement groove is provided, the flip buckle 6 after being flipped down can be effectively accommodated to avoid the phenomenon of blocking interference.

[0030] The bottom surface and the side surface of the flip buckle 6 are both at a right angle of 90 degrees, and the distances between the center point of the pin and the bottom surface and the side surface of the flip buckle 6 are different.

[0031] The working principle of this embodiment is as follows:

[0032] When the flip buckle 6 is upright, the seal is in an open state, and after the flip buckle 6 is horizontally connected to the card slot, the jar is in a sealed state. Specifically, when the flip buckle 6 is lifted up and laid down, the center of the pin shaft of the flip buckle 6 produces an upward displacement, driving the inner cover 2 to produce the same upward displacement and compressing the spring 4. At this time, the inner cover 2 drives the sealing ring 5 to produce the same displacement, and the sealing ring 5 squeezes upward into the gap between the inner wall of the jar 1 and the outer cover 3 to achieve sealing. Conversely, when the flip buckle 6 is laid down and lifted up, the center of the flip buckle pin produces a downward displacement, and with the help of the spring 4 rebound, it drives the inner cover 2 to produce the same downward displacement.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
