[0052] As described in the background art above, a container generally includes a tank body and a top cover, which are arranged together to form a receiving cavity for receiving liquid. The top cover also has a feature that when a user drinks a beverage, the top cover can be opened to expose an opening on the top cover that is connected to the receiving cavity for the user to drink the beverage.

[0053] However, in the above-mentioned container, when the opening on the top cover is opened, the beverage inside the can body is easy to spill out before being consumed, which reduces the user experience.

[0054] Based on the above problems, an embodiment of the present application provides a container. By arranging a dust-proof and overflow-proof cover on the can body, the dust-proof and overflow-proof cover can seal the containing cavity of the can body before the user finishes drinking the beverage in the can body, thereby reducing or preventing the beverage in the can body from overflowing out of the can body, reducing the waste of beverage in the can body, and improving the cleanliness of the outside of the can body, thereby effectively improving the user experience.

[0055] The container provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0056] Figure 1 A schematic diagram of the structure of a container provided in an embodiment of the present application, Figure 2 A schematic diagram of the structure of a tank provided in an embodiment of the present application is shown in FIG. Figure 3 A schematic diagram of an exploded view of a container provided in an embodiment of the present application.

[0057] The present application embodiment provides a container 100, see Figure 1 As shown, the container 100 may include a tank body 110 and a dust and spill prevention cover 120, Figure 2 As shown, the can body 110 may include a can body 111 and a top cover 112. The top cover 112 may be located at the top of the can body 111 and connected to the top of the can body 111. For example, the top cover 112 and the can body 111 may be connected by crimping. For example, the edges of the can body 111 and the top cover 112 may be stacked on each other and then crimped so that the can body 111 and the top cover 112 may be sealed.

[0058] A receiving cavity may be formed between the can body 111 and the top cover 112, and a liquid may be contained in the receiving cavity, for example, a beverage may be contained in the receiving cavity. The top cover 112 may be provided with an openable operating member 1121, and the operating member 1121 may be used to open the top cover 112 so that the top cover 112 may present an opening, so that the user may drink the beverage in the can body 111 through the opening.

[0059] For example, a drinking mouth area 1122 can be set on the top cover 112, and the edge material of the drinking mouth area 1122 can be relatively weak. The operating member 1121 can be set on the drinking mouth area 1122. When it is necessary to open the opening for drinking, the operating member 1121 can be pulled so that the operating member 1121 can pull open the material of the top cover 112 at the drinking mouth area 1122 to form an opening on the top cover 112.

[0060] Combination Figure 3As shown, the dust-proof and overflow-proof cover 120 can be covered on the top cover 112 and detachably connected to the top of the tank body 110. For example, when the user needs to drink a beverage, the dust-proof and overflow-proof cover 120 can be removed from the tank body 111 to drink the beverage in the tank body 110. On the contrary, when the user does not need to drink a beverage, the dust-proof and overflow-proof cover 120 can be covered on the tank body 111 to seal and protect the tank body 111. After the user finishes drinking the beverage, the dust-proof and overflow-proof cover 120 can be removed and installed on the next tank body 110 so that the dust-proof and overflow-proof cover 120 can be recycled, which can effectively improve the utilization rate of the dust-proof and overflow-proof cover 120 and enhance the environmental protection and practicality of the dust-proof and overflow-proof cover 120.

[0061] Compared with the containers in the related art, the embodiment of the present application provides a dust-proof and overflow-proof cover 120 on the can body 110. Before the user finishes drinking the beverage in the can body 110, the dust-proof and overflow-proof cover 120 can seal the containing cavity of the can body 110, thereby reducing or preventing the beverage in the can body 111 from overflowing from the inside of the can body 110 to the outside, reducing the waste of the beverage in the can body 110, and improving the cleanliness of the outside of the can body 111, thereby effectively improving the user experience.

[0062] Moreover, the dust and overflow prevention cover 120 can also prevent external dust and other stains from entering the containing cavity, which can effectively prevent stains from entering the containing cavity and contaminating the beverage in the can body 110, thereby helping to improve the protection of the beverage in the can body 110 and improve the cleanliness of the interior of the container 100.

[0063] Continue to see Figure 3 As shown, in one possible implementation, the dust and overflow prevention cover 120 may include a first cover body 121 and a second cover body 122. The first cover body 121 may be an annular structure. The first cover body 121 may surround the top of the tank body 110 and be detachably connected to the top of the tank body 110. For example, the first cover body 121 and the top of the tank body 110 may be detachably connected by means of a snap connection, a buckle connection, or a threaded connection.

[0064] The second cover 122 can be covered on the first cover 121 and detachably connected to the first cover 121. For example, the top of the second cover 122 can be a sealing structure, and the second cover 122 can seal the tank 110 after being covered on the first cover 121 to prevent dust and overflow. For example, the second cover 122 and the first cover 121 can be detachably connected by means of a snap connection, a buckle connection, or a threaded connection.

[0065] When the user does not need to drink the beverage, the first cover 121 and the second cover 122 can be installed on the can body 111 to seal the can body 111, thereby achieving the effect of dust and spill prevention. When the user needs to drink the beverage, the second cover 122 can be removed from the first cover 121 to expose the opening on the top cover 112 to the outside for drinking.

[0066] After the user has finished drinking all the beverage in the can body 111 , the first cover body 121 can be removed from the can body 110 so that the dust-proof and spill-proof cover 120 can be used in conjunction with the next can body 110 , thereby realizing the recycling of the dust-proof and spill-proof cover 120 .

[0067] Figure 4 A schematic structural diagram of a first cover body provided in an embodiment of the present application.

[0068] See also Figure 4 As shown, the first cover body 121 may include a first top wall 1211, a first inner wall 1212 and a first outer wall 1213. The first top wall 1211 may be an annular structure, the first inner wall 1212 may be arranged on the inner side of the first top wall 1211, and the first outer wall 1213 may be arranged on the outer side of the first top wall 1211.

[0069] The first inner side wall 1212 can be detachably connected to the second cover body 122, for example, the second cover body 122 can be detachably connected to the first inner side wall 1212 by means of a snap connection, a buckle connection, or a threaded connection. The first outer side wall 1213 can be detachably connected to the tank body 110, for example, the first outer side wall 1213 can be detachably connected to the tank body 110 by means of a snap connection, a buckle connection, or a threaded connection.

[0070] When the user needs to drink a beverage, the second cover 122 can be removed from the first inner wall 1212 to separate the second cover 122 from the first cover 121, so as to expose the opening on the top cover 112 to the outside for the user to drink.

[0071] When the user has finished drinking all the beverage in the can body 111, the first outer wall 1213 can be removed from the can body 110 to separate the dust and spill proof cover 120 from the can body 110, so that the dust and spill proof cover 120 can be used in conjunction with the next can body 110 to achieve the recycling of the dust and spill proof cover 120.

[0072] Figure 5 A schematic diagram of the structure of a second cover provided in an embodiment of the present application is shown in FIG. Figure 6 A cross-sectional view of the cooperation between a first cover body and a second cover body provided in an embodiment of the present application.

[0073] See also Figure 5As shown, the second cover body 122 may include a second top wall 1221 and a second inner side wall 1222. The second top wall 1221 may be a circular structure, and the second inner side wall 1222 may be arranged around the second top wall 1221. Figure 6 As shown, the second inner wall 1222 can be detachably connected to the first inner wall 1212 on the first cover body 121, and the second cover body 122 and the first cover body 121 can be detachably connected through the cooperation between the first inner wall 1212 and the second inner wall 1222, so that the user can remove the second cover body 122 from the first cover body 121 to drink the beverage in the can body 110.

[0074] Continue to see Figure 5 and Figure 6 As shown, the second cover 122 may further include a second outer side wall 1223, which may be disposed around the second top wall 1221, and the second outer side wall 1223 may be located outside the second inner side wall 1222, and the second outer side wall 1223 and the first outer side wall 1213 may be flush with the outer side of the can body 110. This may improve the overall neatness of the exterior of the container 100, and help improve the overall aesthetics of the container 100.

[0075] Continue to see Figure 4 and Figure 5 As shown, the inner wall of the first inner side wall 1212 may have a first clamping portion 12121, and the outer periphery of the second inner side wall 1222 may have a second clamping portion 12221 that matches the first clamping portion 12121. Figure 6 As shown, the first clamping portion 12121 and the second clamping portion 12221 can be clamped together, and the first inner side wall 1212 and the second inner side wall 1222 can be detachably connected through the cooperation between the first clamping portion 12121 and the second clamping portion 12221 .

[0076] For example, the first clamping portion 12121 may be a protruding structure as shown in the figure, the second clamping portion 12221 may be a clamping groove structure, and the first clamping portion 12121 may be clamped in the second clamping portion 12221 to connect the first cover 121 with the second cover 122. The operation is simple and the connection is reliable, which can facilitate the assembly between the first cover 121 and the second cover 122, and can improve the reliability and stability of the connection between the first cover 121 and the second cover 122.

[0077] Alternatively, in some examples, the first clamping portion 12121 may also be a clamping slot structure, the second clamping portion 12221 may be a protruding structure, and the second clamping portion 12221 may be clamped in the first clamping portion 12121 to achieve a detachable connection between the first cover body 121 and the second cover body 122.

[0078] Figure 7 A cross-sectional view of a first cover body provided in an embodiment of the present application.

[0079] In the embodiment of the present application, the top of the tank body 110 may have a first connecting portion 113 (see Figure 2 shown), see Figure 7 As shown, the first outer side wall 1213 may have a second connection portion 12131 at one end facing the can body 110, and the second connection portion 12131 may be sleeved on the first connection portion 113 and detachably connected to the first connection portion 113. For example, the first connection portion 113 may be a curling edge between the can body 111 and the top cover 112. The first connection portion 113 on the first outer side wall 1213 may be sleeved on the curling edge and perform interference fit with the curling edge to be connected to the can body 111.

[0080] This can effectively improve the firmness and reliability of the connection between the first cover body 121 and the can body 111, can effectively reduce or avoid the first cover body 121 from falling off the can body 111, and help improve the reliability and stability of the connection between the dust and spill prevention cover 120 and the can body 111.

[0081] For example, see Figure 7 As shown, from the first end of the second connection portion 12131 close to the tank body 110 to the end of the second connection portion 12131 away from the tank body 110 (ie Figure 7 In the x direction), the inner diameter of the second connection portion 12131 can be gradually reduced. For example, the end of the second connection portion 12131 close to the tank body 110 can be the first end, and the end of the second connection portion 12131 away from the tank body 110 can be the second end. It can be understood that, in the direction from the first end to the second end, the inner diameter of the second connection portion 12131 gradually decreases, that is, the inner wall of the second connection portion 12131 is a slope.

[0082] When the end of the second connection part 12131 close to the tank body 110 is sleeved on the first connection part 113, there is a clearance fit between the second connection part 12131 and the first connection part 113. When the end of the second connection part 12131 away from the tank body 110 is sleeved on the first connection part 113, there is an interference fit between the second connection part 12131 and the first connection part 113.

[0083] For example, when the user inserts the tank body 110 from the first end of the second connection part 12131, as the tank body 110 gradually extends deeper into the first outer side wall 1213, the fit between the tank body 110 and the outer side wall becomes tighter and tighter. Until the first connection part 113 on the tank body 110 is matched with the second end of the second connection part 12131, at this time, the second connection part 12131 and the first connection part 113 on the tank body 110 are interference fit, which can effectively improve the firmness and tightness of the fit between the first outer side wall 1213 and the tank body 110.

[0084] During the initial cooperation between the second connection part 12131 and the first connection part 113, its inner diameter is larger and the cooperation with the first connection part 113 is looser, which can reduce or avoid the jamming and the like during the cooperation between the first outer wall 1213 and the tank body 110, and can facilitate the user to put the first outer wall 1213 on the tank body 110, which is beneficial to improve the operability of the assembly between the first cover body 121 and the tank body 110.

[0086] In another possible implementation, see Figure 8 and Fig. 9 As shown, the dust-proof and overflow-proof cover 120 can also be an integrated structure, and the dust-proof and overflow-proof cover 120 can include a top wall 123 and a side wall 124. The side wall 124 can be arranged on the top wall 123 and together with the top wall 123 to form a cover body, the side wall 124 can be detachably connected to the top of the can body 110, and the top wall 123 can be covered on the top cover 112 of the can body 110. When the user needs to drink a beverage, the side wall 124 can be removed from the can body 111 to separate the dust-proof and overflow-proof cover 120 from the can body 110, so that the user can drink the beverage in the can body 110. After the user finishes drinking the beverage, the dust-proof and overflow-proof cover 120 can be installed on the next can body 110, so that the dust-proof and overflow-proof cover 120 can be recycled, so as to improve the utilization rate of the dust-proof and overflow-proof cover 120 and enhance the environmental protection and practicality of the dust-proof and overflow-proof cover 120.

[0087] Among them, in the embodiment of the present application, the can body 110 can be a metal can body, for example, the can body 110 can be a can, etc., and the dust and spill prevention cover 120 can be a plastic part, and the dust and spill prevention cover 120 can be formed by injection molding, stamping, etc.
