[0023] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0024] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0025] In the following, in conjunction with the accompanying drawings, a metal can for reducing can body deformation provided by an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0026] See also Figures 1 to 4 The embodiment of the present application provides a metal can with reduced deformation of the can body, the metal can with reduced deformation of the can body comprising: a metal can body 100, a bottom plate 200 and a cover body 300, the metal can body 100 comprising a first opening end and a second opening end 150 opposite to each other, the shape of the first opening end matches the shape of the second opening end 150, and the first opening end is aligned with the second opening end 150, the bottom plate 200 is connected to the first opening end to close the first opening end, and the cover body 300 is connected to the second opening end 150 to close the second opening end 150;

[0027] The metal can body 100 includes an expansion area 110 protruding outward relative to the target space area 400, wherein the target space area 400 is a columnar area formed with the first opening end as the bottom surface and the second opening end 150 as the top surface, and the expansion area 110 is arranged around the axis of the metal can body 100;

[0028] The outer side wall of the metal can body 100 is provided with an annular reinforcement rib 120 , the axis of the annular reinforcement rib 120 coincides with the axis of the metal can body 100 , and the annular reinforcement rib 120 is located between the expansion area 110 and the second opening end 150 .

[0029] Among them, the metal can that reduces the deformation of the can body can be various metal cans for storing food, for example, it can be a metal can for storing milk powder, or a metal can for storing beverages, etc. The bottom plate 200 can be a metal bottom plate 200 of various metal cans in the related art, and the connection method between the bottom plate 200 and the metal can body 100 can be the same as the connection method between the can body of the metal can and the bottom plate 200 in the related art. For example, in some embodiments of the present application, the first opening end of the metal can body 100 can be provided with a first annular flange facing outward, and the first annular flange and the outer wall of the metal can body 100 are surrounded to form an annular groove, and the edge of the cover body 300 can be provided with a second annular flange facing inward, so that the second annular flange can be embedded in the first annular flange and the annular groove, and then the first annular flange and the second annular flange are pressed toward one side of the outer wall of the metal can body 100, so that the first annular flange, the second annular flange and the outer wall of the metal can body 100 are tightly fitted in sequence, thereby achieving the sealing of the first opening end.

[0030] The cover 300 can be any of the covers 300 in the related art, for example, a metal cover with a pull ring, a plastic cover or a plastic film. When the cover 300 is a metal cover with a pull ring, the connection between the cover 300 and the metal can body 100 can be the same as the connection between the can body and the cover 300 of the can in the related art. When the cover 300 is a plastic cover, the cover 300 and the metal can body 100 can be connected by snap fastening, for example, an annular groove 140 can be provided on the outer side wall of the metal can body 100, and correspondingly, an annular protrusion can be provided on the inner side wall of the cover 300, and when the cover 300 and the metal can body 100 are connected, the annular protrusion is embedded in the annular groove 140. In addition, when the cover 300 is a plastic film, the cover 300 and the metal can body 100 can be connected by bonding to seal the second opening end 150.

[0031] The shape of the target space region 400 may vary according to the shapes of the first opening end and the second opening end 150. For example, see Figure 1, when the first opening end and the second opening end 150 are both circular, the target space area 400 may be a cylindrical area formed by the first opening end as the bottom surface and the second opening end 150 as the top surface. It should be noted that the target space area 400 is the internal area of ​​the metal can that reduces the deformation of the can body. The target space area 400 introduced in the embodiment of the present application is only to illustrate the expansion direction of the expansion area 110, that is, the target space area 400 is only a reference position, and the target space area 400 is not a physical structure in the metal can that reduces the deformation of the can body.

[0032] In some embodiments of the present application, the annular reinforcement rib 120 may protrude outward from the outer side wall of the metal can body 100, and the annular reinforcement rib 120 is not a reinforcement rib formed by expanding the metal can body 100 outward, but an annular reinforcement rib 120 formed by accumulating metal on the surface of the metal can body 100.

[0033] In this embodiment, the metal can body 100 includes the expansion area 110, which is conducive to enhancing the pressure-bearing strength of the metal can body 100. At the same time, by further providing an annular reinforcing rib 120 between the expansion area 110 and the second opening end 150, it is conducive to further enhancing the pressure-bearing strength of the metal can body 100, thereby alleviating the problem of the existing metal can being easily deformed under pressure.

[0034] Optionally, the cover body 300 is in a hollow cylindrical shape, and the cover body 300 includes an open end and a closed end, and the closed end includes a flip cover that can be opened or closed;

[0035] The open end of the cover body 300 is buckled on the metal can body 100 along the second open end of the metal can body 100, and the cover body 300 is fixedly connected to the metal can body 100, and the open end of the cover body 300 abuts against the end surface of the annular reinforcement rib 120 facing the second open end 150.

[0036] The cover 300 can be any plastic cover 300 that can be flipped. Of course, the cover 300 can also be made of other materials such as metal according to actual needs. The flip of the cover 300 can open or close the second opening end 150 .

[0037] It is understandable that after the cover body 300 is connected to the metal can body 100, a certain extrusion force can be formed between the opening end of the cover body 300 and the annular reinforcement rib 120, so that the opening end of the cover body 300 abuts against the end face of the annular reinforcement rib 120 facing the second opening end 150.

[0038] In this embodiment, by making the open end of the cover body 300 abut against the end face of the annular reinforcement rib 120 toward the second open end 150, the sealing of the joint between the open end of the cover body 300 and the metal can body 100 can be improved, which is beneficial to improving the overall sealing of the metal can.

[0039] Optionally, the end surface of the annular reinforcing rib 120 facing the second opening end 150 is an annular plane, and the end surface of the annular reinforcing rib 120 facing the second opening end 150 is in contact with the opening end of the cover body 300 .

[0040] In this embodiment, since the end face of the annular reinforcement rib 120 facing the second opening end 150 is an annular plane, and the end face of the annular reinforcement rib 120 facing the second opening end 150 is in contact with the opening end of the cover body 300, it is beneficial to further improve the sealing of the joint between the opening end of the cover body 300 and the metal can body 100.

[0041] Optionally, the cross-sectional area of ​​the annular reinforcement rib 120 gradually decreases from the second opening end 150 to the first opening end.

[0042] In this embodiment, the cross-sectional area of ​​the annular reinforcement rib 120 is gradually reduced from the second opening end 150 to the first opening end. In this way, the annular reinforcement rib 120 can be smoothly connected to other positions of the metal can body 100, thereby avoiding the problem of sharp protrusions on the outer wall of the metal can body 100 due to the provision of the annular reinforcement rib 120.

[0043] Optionally, the outer diameter of the end surface of the annular reinforcing rib 120 facing the second open end 150 is equal to the outer diameter of the open end of the cover body 300 .

[0044] It can be understood that the outer wall of the annular reinforcing rib 120 facing the second open end 150 is aligned with the outer wall of the open end of the cover body 300 .

[0045] In this embodiment, the outer diameter of the end surface of the annular reinforcement rib 120 facing the second opening end 150 is equal to the outer diameter of the opening end of the cover body 300. In this way, the outer wall of the annular reinforcement rib 120 facing the second opening end 150 can be aligned with the outer wall of the opening end of the cover body 300, which is beneficial to improve the flatness of the joint between the annular reinforcement rib 120 and the cover body 300, and further improve the overall aesthetics of the metal can.

[0046] Optionally, the cover 300 is snap-fitted to the metal can body 100 .

[0047] In some embodiments of the present application, the second open end 150 of the metal can body 100 is provided with an annular curling edge 130 curled outward, the annular curling edge 130 is spaced apart from the annular reinforcing rib 120, and an annular groove 140 is formed between the annular curling edge 130 and the annular reinforcing rib 120;

[0048] The inner side wall of the cover body 300 is provided with a buckle matching the annular slot 140 , and the cover body 300 is buckled with the annular slot 140 through the buckle.

[0049] The buckle includes a plurality of protrusions distributed on the inner wall of the cover body 300 , and the plurality of protrusions are arranged in a ring array with the axis of the ring-shaped reinforcing rib 120 as the axis.

[0050] In this embodiment, the cover body 300 is snap-fitted with the metal can body 100 , thereby facilitating the metal can body 100 and the cover body 300 to be processed separately and assembled into a mold.

[0051] In some embodiments of the present application, the expansion area 110 is an arc-shaped expansion area 110 extending from the annular reinforcement rib 120 to the first opening end. The first opening end and the second opening end 150 are circular opening ends, and the diameter difference between the maximum diameter of the expansion area 110 and the diameter of the first opening end is greater than 1 mm and less than 5 mm.

[0052] The maximum diameter of the expansion region 110 refers to the diameter of the position where the diameter of the expansion region 110 is the largest, that is, the diameter of the position where the expansion region 110 is farthest from the target space region 400 .

[0053] It is understood that the larger the diameter of the first opening end is, the larger the diameter difference between the maximum diameter of the expansion area 110 and the diameter of the first opening end can be. For example, when the diameter of the first opening end is 4 cm, the diameter difference between the maximum diameter of the expansion area 110 and the diameter of the first opening end can be: 2 mm. For another example, when the diameter of the first opening end is 5 cm, the diameter difference between the maximum diameter of the expansion area 110 and the diameter of the first opening end can be: 2.5 mm.

[0054] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
