[0027] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0028] Existing metal storage boxes are generally made by directly stamping plates. However, the inner wall of the box is easily contaminated. In some applications, users easily leave fingerprints on the inner wall during use, contaminating the box. In other applications, the food inside the box is not easy to pour out, or the pouring speed is slow, causing inconvenience in use.

[0029] For this reason, Figure 1 and Figure 2As shown, the storage box proposed by the utility model includes a box body 100 and a plurality of protrusions 110, wherein the box body 100 is a metal part, and the plurality of protrusions 110 are integrally connected to the box body 100 and are distributed on the inner wall of the box body 100. It should be noted that the entire inner wall of the metal box body 100 is covered with protrusions 110, so that the inner wall of the box body 100 has good anti-slip properties for human hand holding, and good anti-scratch properties for rigid collision. In addition, the protrusions 110 can support the bottom of various solid storage objects, such as supporting the bottom wall of granular food. At the same time, there are gaps between the plurality of protrusions 110, that is, the gas flowability under the food is good, which can make the internal storage objects pour out better and faster, and it is more convenient to use.

[0030] In some manufacturing processes, grooves are formed on the plate surface after the metal plate is roll-formed, wherein the extension path of the groove depends on the roller used in the rolling process, and can be designed according to actual needs. In contrast to the groove, the grooves are separated by protrusions 110, and then the plate with protrusions 110 is formed into a box-shaped structure through stamping, so that the inner wall of the box body 100 is eventually covered with protrusions 110. It is easy to understand that rolling is a processing method that does not remove material, and the plate after rolling has a higher density and a higher hardness, so that the inner wall of the box body 100 has better scratch resistance. In general, the box body 100 can be considered as a container with a certain height, so that the side wall of the box body 100 has a certain visibility, and the user can observe the protrusions 110 arranged on the inner wall. In this regard, the protrusions 110 as a whole can form a unique texture, and the box body 100 has a good appearance.

[0031] In some related technologies, the grooves are arranged at intervals. For example, the outer wall of the box body is processed by roller pressing to form grooves to improve the heat conduction efficiency. The grooves are mostly arranged at intervals, and it is necessary to set a large number of independent convex strips on the roller to process the grooves. However, the convex strips are easily broken during the roller processing, causing the entire roller to fail and become unusable. The frequency of replacement of the roller is high, resulting in high processing costs. For this reason, since the groove corresponding to the box body 100 of the present application is set on the inner wall of the box body 100, which is different from the position set on the outer wall of the box body, the problems solved and the effects of the two are different. In some embodiments of the present invention, refer to Figure 1 and Figure 2 A connecting groove 101 is formed between the plurality of protrusions 110. The connecting groove 101 is a mesh structure that is distributed vertically and horizontally and is connected. That is, the convex strips provided on the pressure roller are all connected, and all connected grooves can be processed on the surface of the plate. On the one hand, the connecting groove 101 of the mesh connecting structure can make the gas flow under the stored objects better, for example, it can make it easier to pour out food such as rice. On the other hand, since the convex strips provided corresponding to the pressure roller are all connected, the overall structural rigidity is better and not easy to collapse, which effectively increases the service life of the pressure roller.

[0032] In some embodiments, the shapes of the plurality of protrusions are all the same (not shown in the figure), and the plurality of protrusions are arranged in an array on the inner wall of the box body. In some embodiments, the shapes of the protrusions 110 are different, such as Figure 2 As shown, the protrusion 110 includes a first protrusion 111 and a second protrusion 112, the shape of the first protrusion 111 and the shape of the second protrusion 112 are different, and the first protrusion 111 and the second protrusion 112 are arranged alternately. For example, the first protrusion and the second protrusion are square and polygonal, respectively, or the first protrusion and the second protrusion are two irregular shapes, respectively (not shown in the figure). In some embodiments of the utility model, the first protrusion 111 has a first elliptical shape along a cross section perpendicular to the thickness direction of the first protrusion 111, and the major axis of the first elliptical shape is arranged horizontally, and the second protrusion 112 has a second elliptical shape along a cross section perpendicular to the thickness direction of the second protrusion 112, and the major axis of the second elliptical shape is arranged longitudinally. The first protrusion 111 and the second protrusion 112 are arranged with a stronger regularity and a better overall aesthetics. Optionally, referring to Figure 2 The first bump 111 and the second bump 112 are arranged alternately in the transverse direction, or the first bump and the second bump are arranged alternately in the longitudinal direction (not shown in the figure); or the first bump and the second bump are arranged alternately in both the transverse direction and the longitudinal direction, that is, the first bump is surrounded by the second bumps, and the second bump is surrounded by the first bumps (not shown in the figure).

[0033] In some embodiments, the multiple protrusions have the same shape but different sizes. For example, the protrusions include a first protrusion and a second protrusion, the shape of the first protrusion and the shape of the second protrusion are the same and scaled, and the first protrusion and the second protrusion are arranged alternately. For example, the first protrusion and the second protrusion are heart-shaped patterns of different sizes, waves of different thicknesses, etc.

[0034] It is easy to understand that, in addition to being divided into the first protrusion 111 and the second protrusion 112 , the protrusion 110 can also have more shapes depending on the design. For example, the protrusion 110 also includes a third protrusion (not shown in the figure) that is different from the first protrusion 111 and the second protrusion 112 .

[0035] In some embodiments, according to different protrusion processing or molding methods, the end of the protrusion is a spherical structure (not shown in the figure), the end of the protrusion is used to support the stored objects, and there are corresponding gaps between adjacent protrusions, so that the storage objects have good circulation under them. Figure 1 As shown, the end face of the protrusion 110 is a plane, and the stored object is supported by a plane contact, which reduces the embedding of small granular stored objects such as rice between multiple protrusions 110, further improves the pouring performance of the stored object, and facilitates its pouring.

[0036] In some applications, when the metal plate is processed by roll forming and then stamped to form the box body 100, if the thickness of the metal plate is thin, the outer wall of the box body 100 will also form a corresponding concave-convex structure. In some applications, the concave-convex structure of the outer wall of the box body 100 has the effects of anti-slip, anti-scratch, and improving thermal conductivity. In some embodiments, in order to hide the concave-convex structure of the outer wall of the box body 100, the outer wall of the box body 100 is provided with a scratch-resistant coating, so that the box body 100 can be designed into an ultra-thin structure, for example, the thickness of the box body 100 is 0.2mm, which can save material costs. Optionally, the scratch-resistant coating is coated with epoxy resin spray particles. It should be noted that epoxy resin spray particles are a coating technology. It is a coating technology that sprays epoxy resin paint onto the surface of an object in the form of particles, by granulating the epoxy resin and spraying it onto the coated object under appropriate conditions, and then curing to form a coating with good properties such as hardness, wear resistance, and chemical corrosion resistance. Epoxy resin spray particles have the advantages of easy construction, uniform coating and strong adhesion.

[0037] Refer to Figure 1 and Figure 2 , the protrusion 110 is in the form of a sheet, and the thickness of the protrusion 110 is A, satisfying: 0.08mm≤A≤0.12mm. Optionally, A=0.1mm. In some embodiments, the box body 100 is a stainless steel part, and the thickness of the box body 100 is B, satisfying: 0.2mm≤B≤0.5mm. Optionally, B=0.35mm. In some processing and manufacturing, a steel plate with a thickness of 0.45mm is selected for roller processing, and a corresponding concave-convex structure is formed on one side of the steel plate. Then, the steel plate is stamped to form the box body 100, and the concave-convex structure is located on the inner wall of the box body 100.

[0038] It is easy to understand that the box body 100 has a variety of external designs, for example, the box body is a standard external shape such as a cylindrical shape or a prismatic shape (not shown in the figure). In some embodiments, when the box body 100 is made by stamping, the external shape of the box body 100 depends on the design of the stamping die. By increasing the number of stampings, a more unique external shape of the box body 100 can be designed to meet the personalized needs of different users. In some embodiments, the outer surface of the box body is a single curved surface (not shown in the figure). In some embodiments of the present invention, refer to Figure 1 The box body 100 has a peripheral wall and a bottom wall, and the inner peripheral wall and the inner bottom wall are both provided with protrusions 110. For example, the peripheral wall is arc-shaped (not shown in the figure), and the bottom wall is flat, so that the bottom wall is suitable for the box body 100 to be stably placed on a flat surface. For another example, the box body 100 is square-shaped, and the peripheral wall includes a plurality of flat walls connected in sequence, so that the user can hold and move the box body 100. Further, referring to Figure 1, the connection between the peripheral wall and the bottom wall is a first smooth transition wall, and similarly, the connection between adjacent plane walls in the peripheral wall is a second smooth transition wall. It is easy to understand that a smooth transition wall is provided between adjacent wall surfaces to avoid sharp transition designs of acute angles or right angles, to avoid scratching the user, and to make it safer for the user to contact and use. It is easy to understand that when the box body 100 is formed by stamping, a smooth transition structure can be easily processed at the connection between adjacent planes during the stamping process. For example, the first smooth transition wall and the second smooth transition wall are both rounded structures. In addition, the first smooth transition wall and the second smooth transition wall are both arranged with protrusions 110, and the overall structural property is better. At the same time, the protrusions 110 as a whole can form a more regular arrangement, and the aesthetics are better.

[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
