The most common bottle caps are connected to the storage containers by threads. This structure is simple but has a low degree of sealing, especially when used to store food and other items, the preservation effect is poor. Therefore, there is another storage container, which has a sealing structure on its lid, and the lid and the storage container are firmly locked by a locking structure. This structure has better sealing performance, but the structure is complex, the product volume is large, the operation is inconvenient, and the manufacturing cost is high.

[0003] The present invention is just produced based on the above-mentioned shortcomings. [Summary of the invention]

[0026] The invention will be further described below in conjunction with the accompanying drawings:

[0027] The directions described in the specification of the invention, such as "up", "down", "left", "right", "front", "back", etc., are based on the directions of the drawings and are intended to facilitate the description of the relationship between the various components. They do not indicate the unique or absolute positional relationship between the various components. They are only one of the implementation methods of the invention and are not a limitation on its implementation method.

[0028] refer to Figures 1 to 6 A container sealing cover with a locking function comprises a panel 1, such as Figure 1 and Figure 6 As shown, the sealing cover is arranged at the opening of the container A and abuts against the inner wall of the container A, as shown in FIG. Figure 4 and Figure 5 As shown, a lifting bracket 3 capable of moving up and down relative to the panel 1 is disposed below the panel 1, and an operating member 2 capable of pushing the lifting bracket 3 to move up and down is disposed between the panel 1 and the lifting bracket 3. Figure 1 and Figure 4As shown, the panel 1 is connected to the operating member 2, the operating member 2 is connected to the lifting bracket 3, the lifting bracket 3 is connected to the sealing member 4, and the sealing member 4 is provided with a circle of sealing parts 41 for abutting against the inner wall of the container A on the four edges thereof, the sealing part 41 is made of an elastic material or the entire sealing member 4 is made of an elastic material, for example, part of or the entire sealing member 4 is made of rubber, silicone or soft plastic, a circle of sealing parts 41 constitutes a circle or a rounded polygon, thus forming a circle of sealing structure abutting against the bottle mouth or can mouth of the container A, the sealing part 41 has a guide surface 42 which is gradually inclined outward from bottom to top, and the panel 1 is provided with a guide part 11 abutting against the guide surface 42.

[0029] In more detail, Figure 1 and Figure 4 As shown, the operating member 2 is screwed on the panel 1 in the up-down direction, and the top of the operating member 2 passes through the panel 1 and is exposed on the upper surface of the panel 1. A gripping portion 24 for a person to hold is provided on the top of the operating member 2. In this way, the user can hold the gripping portion 24 to push the operating member 2 to rotate, so that the operating member 2 can be lifted up and down relative to the panel 1. When the operating member 2 is screwed out of the panel 1, the operating member 2 moves upward, driving the lifting bracket 3 to move upward, and the guide surface 42 is stretched outward under the top pressure of the guide portion 11, so that the entire sealing portion 41 expands to the surroundings. At the same time, the sealing portion 41 has elasticity, and then the sealing portion 41 can be tightly attached to the inner wall of the container A to achieve the effect of locking and sealing; on the contrary, when the operating member 2 is screwed into the panel 1 downward, the operating member 2 moves downward, driving the lifting bracket 3 to move downward, and the guide surface 42 shrinks inward due to the elasticity, and the sealing portion 41 is loosened from the inner wall of the container A, so that the container sealing cover can be separated from the container A. This not only has a simple structure, a small product size, a thin thickness, saves materials and reduces production costs, but also can save force in pushing the operating member 2 through the threaded connection, making the operation smoother and more labor-saving for users, and convenient.

[0030] Of course, the operating member 2 and the panel 1 can also be slidably connected. The operating member 2 is slidably connected to the panel 1, and the operating member 2 can move up and down relative to the panel 1. At the same time, a locking structure is set between the two, so that the two can be locked after the operating member 2 moves up or down relative to the panel 1, which can also be achieved.

[0031] like Figure 2 , Figure 3 and Figure 4As shown, the lifting bracket 3 is provided with a snap-fitting convex ring 31, and the lower part of the operating member 2 is provided with a plurality of buckles 21 snap-fitted under the snap-fitting convex ring 31, and the lifting bracket 3 is provided with a guide ring 32, and the operating member 2 is provided with a sleeve ring 22 which is sleeved on the outer side of the guide ring 32 from top to bottom, and the operating member is provided with a rib 23 on the inner side of the sleeve ring 22, and the top of the guide ring 32 is provided with a supporting surface 33 which abuts against the bottom of the rib 23, so as to realize the connection between the lower part of the operating member 2 and the lifting bracket 3, when the operating member 2 moves upward, the buckle 21 is subjected to force on the snap-fitting convex ring 31, thereby driving the lifting bracket 3 to move upward, and when the operating member 2 moves downward, the rib 23 is subjected to force on the supporting surface 33, thereby driving the lifting bracket 3 to move downward, which not only has a simple structure and can reduce the thickness of the product, but also facilitates the assembly of the operating member 2 and the lifting bracket 3.

[0032] As a further optimization, Figure 2 and Figure 3 As shown, the guide ring 32 is provided with a limiting portion 34 which abuts against the rib portion 23 after the operating member 2 rotates a certain angle. When the operating member 2 rotates to a preset angle, it abuts against the limiting portion 34 to prevent it from further rotating. The lifting and lowering range of the lifting bracket 3 is determined according to the expansion range of the sealing portion 41 to the surroundings. The preset rotation angle of the operating member 2 is determined according to the lifting and lowering range of the lifting bracket 3 and the thread specifications of the operating member 2, so that the user can operate it more smoothly and with less effort.

[0033] As a further optimization, Figure 2 and Figure 3 As shown, the lifting bracket 3 is provided with a circle of card grooves 35, and the sealing member 4 is provided with a card connection portion 43 that is inserted into the card groove 35. The card connection portion 43 can be made into a shape matching the card groove 35, that is, it can be made into a complete circle, or it can be made into a plurality of protrusions that are inserted into the card groove 35, so as to facilitate assembly. At the same time, the sealing performance between the sealing member 4 and the lifting bracket 3 is improved, thereby improving the sealing performance of the entire container sealing cover.

[0034] like Figure 1 and 2 As shown, the gripping portion 24 is a knob handle.

[0035] As a further optimization, the operating member 2 and the panel 1 are connected by a left-handed thread, so that when the user rotates the operating member 2 counterclockwise, the sealing portion 41 is loosened from the inner wall of the container A. When the user rotates the operating member 2 clockwise, the sealing portion 41 is tightly pressed against the inner wall of the container A, and the sealing cover is locked, which is more in line with the usage habits of ordinary people and makes the user's operation more convenient.

[0036] In more detail, Figures 2 to 4As shown, the lifting bracket 3 is provided with a downwardly concave cavity 36, and the panel 1 is provided with a guide plate 12 extending downward and inserted into the cavity 36. The guide plate 12 can be provided with an annular structure forming a circle, and a plurality of guide plates 12 can also be provided distributed along the side wall of the cavity 36. The guide plate 12 is in close contact with the inner wall of the cavity 36, which is equivalent to the side wall of the entire cavity 36 being sleeved on the guide plate 12, so that the lifting bracket 3 is slidably connected to the panel 1.

[0037] The container sealing cover has a locking function, wherein the sealing member 4 is circular or rounded polygonal.
