It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0022] The following description, in conjunction with the accompanying drawings, details a metal can for reducing can body deformation provided by the embodiments of this application through specific examples and application scenarios.
[0023] Please see Figure 1-2 This application provides a metal can that reduces body deformation. The metal can that reduces body deformation includes: a metal can body 100, a bottom plate 200, and a lid 300. The metal can body 100 includes a first opening end 101 and a second opening end 102 opposite to each other. The shape of the first opening end 101 matches the shape of the second opening end 102, and the first opening end 101 and the second opening end 102 are aligned. The bottom plate 200 is connected to the first opening end 101 to close the first opening end 101. The lid 300 is connected to the second opening end 102 to close the second opening end 102.
[0024] The metal can body 100 includes an expansion region 103 that protrudes outward relative to the target space region 400, wherein the target space region 400 is a cylindrical region formed with the first opening end 101 as the bottom surface and the second opening end 102 as the top surface, and the expansion region 103 is arranged around the axis of the metal can body 100.
[0025] The expansion region 103 is provided with an annular deformation part 104, which is arranged around the axis of the metal can body 100.
[0026] The metal can used to reduce deformation can be any type of metal can for storing food, such as a metal can for storing milk powder or a metal can for storing beverages. The base plate 200 can be any metal base plate 200 found in related technologies, and the connection between the base plate 200 and the metal can body 100 can be the same as the connection between the can body and the base plate 200 in related technologies. For example, in some embodiments of this application, the first opening end 101 of the metal can body 100 can be provided with an outwardly facing first annular flange. The first annular flange and the outer wall of the metal can body 100 form an annular groove. The edge of the cover 300 can be provided with an inwardly facing second annular flange, allowing the second annular flange to be embedded in the first annular flange and the annular groove. Then, the first and second annular flanges are pressed together towards 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 sequentially and tightly fitted, thereby achieving a seal at the first opening end 101.
[0027] The aforementioned cap 300 can be any type of cap 300 in the related art, such as a metal cap with a pull ring, a plastic cap, or a plastic film. When the cap 300 is a metal cap with a pull ring, the connection method between the cap 300 and the metal can body 100 can be the same as the connection method between the can body and the cap 300 in the related art. When the cap 300 is a plastic cap, the cap 300 and the metal can body 100 can be connected by a snap-fit. For example, an annular groove 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 cap 300. When the cap 300 and the metal can body 100 are connected, the annular protrusion is embedded in the annular groove. Furthermore, when the cap 300 is a plastic film, the cap 300 and the metal can body 100 can be connected by adhesive bonding to seal the second opening end 102.
[0028] The shape of the target space region 400 can vary according to the shapes of the first opening end 101 and the second opening end 102, for example, see [link to relevant documentation]. Figure 2When both the first opening end 101 and the second opening end 102 are circular, the target space region 400 can be a cylindrical region formed with the first opening end 101 as the bottom surface and the second opening end 102 as the top surface. Correspondingly, when both the first opening end 101 and the second opening end 102 are polygonal, the target space region 400 can be a prism-shaped region. It should be noted that the target space region 400 is the internal region of the metal can that reduces can body deformation. The target space region 400 introduced in this embodiment is only to illustrate the expansion direction of the expansion region 103; that is, the target space region 400 is only a reference position, and it is not a physical structure within the metal can that reduces can body deformation.
[0029] In some embodiments of this application, the processing of the metal can body 100 may include: after rolling the metal can into a barrel shape, using a mold to expand the metal can to form the expansion region 103.
[0030] In some embodiments of this application, the annular deformation portion 104 may be an annular groove recessed inward from the expansion region 103. In other embodiments of this application, the annular deformation portion 104 includes an annular protrusion protruding outward from the expansion region 103. The cross-sectional shape of the annular deformation portion 104 is arc-shaped or rectangular.
[0031] In this embodiment, by including an expansion region 103 in the metal can body 100, the pressure-bearing strength of the metal can body 100 is enhanced. Furthermore, by further providing an annular deformation portion 104 in the expansion region 103, the pressure-bearing strength of the metal can body 100 is further enhanced, thereby alleviating the problem of existing metal cans being easily deformed under pressure.
[0032] Please see Figure 1-2 In some embodiments of this application, when the cross-sectional shape of the expansion region 103 is arc-shaped, the expansion region 103 is an arc-shaped expansion region 103 extending from the first opening end 101 to the second opening end 102. The annular deformation portion 104 is an annular protrusion protruding outward from the expansion region 103, and the cross-sectional shape of the annular deformation portion 104 is arc-shaped.
[0033] Please see Figure 3 In other embodiments of this application, the expansion region 103 includes at least two sub-expansion regions 1031, which are spaced apart along the axial direction of the metal can body 100 and surround the axial direction of the metal can body 100. Each sub-expansion region 1031 is provided with the annular deformation portion 104. Each sub-expansion region 1031 has a rectangular cross-sectional shape.
[0034] In this embodiment, since the cross-sectional shape of the annular deformation part 104 can be arc-shaped or rectangular, it is advantageous to process the metal can with reduced body deformation into various shapes, thereby improving the diversity of the metal can shape with reduced body deformation.
[0035] Optionally, please see Figure 1 The expansion region 103 is provided with a plurality of annular deformation portions 104, which are arranged at intervals along the axial direction of the metal can body 100 in the expansion region 103.
[0036] In this embodiment, by providing a plurality of annular deformation portions 104 in the expansion region 103 and arranging the plurality of annular deformation portions 104 at intervals along the axial direction of the metal can body 100 in the expansion region 103, it is beneficial to increase the coverage area of the annular deformation portions 104, thereby further enhancing the pressure-bearing strength of the metal can body 100.
[0037] Optionally, the outer wall of the metal can body 100 is provided with anti-slip texture.
[0038] The anti-slip texture can be various shapes of texture processed on the outer wall of the metal can body 100, and the texture can be raised texture or recessed texture.
[0039] In this embodiment, by providing anti-slip texture on the outer wall of the metal can body 100, the risk of the can falling off can be avoided when the user holds the metal can to reduce deformation of the can body.
[0040] Optionally, the outer wall of the metal can body 100 is provided with a groove that matches the finger.
[0041] The number of grooves can be one or at least two to five.
[0042] In this embodiment, the shape of the groove can be the same as the shape of a human finger. In this way, when the user holds the metal can that reduces deformation of the can body, the finger can be embedded in the corresponding groove, which helps to avoid the risk of the can falling off during the process of holding the metal can that reduces deformation of the can body.
[0043] In some embodiments of this application, the first opening end 101 and the second opening end 102 are both circular opening ends, and the diameter difference between the maximum diameter of the expansion region 103 and the diameter of the first opening end 101 is greater than 0 mm and less than 5 mm. The first opening end 101 and the second opening end 102 are both circular opening ends, the diameter of the first opening end 101 is equal to the diameter of the second opening end 102, and the diameter of the first opening end 101 ranges from 3 cm to 27 cm.
[0044] The maximum diameter of the expansion region 103 refers to the diameter of the position where the diameter of the expansion region 103 is the largest, that is, the diameter of the expansion region 103 at the position farthest from the target space region 400.
[0045] It is understandable that the larger the diameter of the first opening end 101, the larger the diameter difference between the maximum diameter of the expansion region 103 and the diameter of the first opening end 101 can be. For example, when the diameter of the first opening end 101 is 4cm, the diameter difference between the maximum diameter of the expansion region 103 and the diameter of the first opening end 101 can be 2mm. As another example, when the diameter of the first opening end 101 is 5cm, the diameter difference between the maximum diameter of the expansion region 103 and the diameter of the first opening end 101 can be 2.5mm.
[0046] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
