[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0051] In this application, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0052] The existing metal packaging box includes a box cover and a box bottom, wherein the box cover and the box bottom are hinged by a hinge 200, and the hinge 200 is an integral structure with the box cover and / or the box bottom, and the overall thickness of the hinge 200 is relatively thick, requiring the use of a die-casting or machining process, but this type of packaging box is not only complex to process and form, but also has a high manufacturing cost.

[0053] To solve this problem, refer to Figures 1 to 9In one embodiment of the present application, a metal packaging box is provided, comprising a hinge 200 and two relatively rotatable shells 100. The two relatively rotatable shells 100 include a first shell 110 and a second shell 150. The metal packaging box has a closed state in which the two shells 100 are close to each other to form a closed accommodating space and an open state in which the two shells 100 are away from each other. The closed state can be referred to as Figure 1-2 , open status can refer to Figure 3 The accommodating space can be used to hold cosmetics (such as pressed powder, loose powder, air cushion, etc.). When the user opens the two shells 100 to an open state, the cosmetics can be used.

[0054] The hinge 200 (made of metal) includes a first connecting member 210 and a second connecting member 220 that are pivotally connected, wherein the first housing 110 is formed by a metal sheet and is welded to the first connecting member 210; and / or the second housing 150 is formed by a metal sheet and is welded to the second connecting member 220. In this embodiment, the welding between the hinge 200 and the housing 100 can be laser welding, and of course other welding methods can also be used, which is not specifically limited.

[0055] In this embodiment, the preferred thickness of the metal sheet is 0.1 to 2 mm. Since the metal sheet is relatively thin, the shell 100 can be given a preset shape using a stamping process. The metal packaging box of the present application is designed by separating the shell 100 and the thicker hinge 200, and connecting the corresponding parts by welding. Compared with the prior art that uses die-casting or machining as an integrated molding, it not only simplifies the processing difficulty but also reduces the cost.

[0056] In this embodiment, the metal used for the hinge 200 and the housing 100 has a tensile strength of 80-100 N / mm. 2 , the elongation is 1 to 10%.

[0057] refer to Figure 3 to Figure 9 The first shell 110 includes a first sink 120 formed by a metal sheet and a first surround 130 surrounding the first sink 120. The first connector 210 is welded to the first surround 130. In order to weld with the first connector 210 at a predetermined position, the first surround 130 has a first notch 131. The first connector 210 is placed in the first notch 131. This design can quickly determine the position and facilitate welding. Of course, the first notch 131 can be formed by the first surround 130 extending inward from the edge (see Figure 4a ), or a closed gap (see Figure 5a and Figure 6c ), which can be set according to specific needs.

[0058] The first surrounding edge 130 and the second surrounding edge 170 involved in the present application both have a top and a bottom relative to each other. Figure 4a as well as Figure 5a As shown, the arrow direction is from the top to the bottom of the box.

[0059] In this embodiment, the first connecting member 210 is flush with the back side of the first surrounding edge 130 (the back side is specifically the side facing the first sink 120), which not only makes the welding more beautiful, but also ensures the rotational coordination with the second connecting member 220, thereby avoiding the problem of rotational interference with the second shell 150 due to improper welding position during welding.

[0060] Similarly, the second housing 150 has a second sink 160 formed by a metal sheet and a second surround 170 surrounding the second sink 160, and the second connector 220 is welded to the second surround 170. To increase the volume of the accommodating space, the first sink 120 is disposed toward the top and the second sink 160 is disposed toward the bottom.

[0061] Similarly, in order to weld with the second connecting member 220 at a predetermined position, the second surrounding edge 170 has a second notch 171 to avoid the first connecting member 210. The second connecting member 220 is arranged on the back side of the second surrounding edge 170 (the back side is specifically the side facing the second sink 160), and the second connecting member 220 is flush with the edge of the second notch 171. In this embodiment, in order to facilitate the welding of the first connecting member 210 / the second connecting member 220 and its corresponding housing 100, the positioning can be controlled by a jig during assembly welding, and then the two can be combined into one by a laser welding process.

[0062] For further reference, Figure 4a to Figure 7b , the second connecting members 220 are arranged in pairs on both sides of the first connecting member 210. The second connecting members 220 may be independent entities arranged on both sides of the second notch 171 (see Figure 7a ), or it may be an integrated structure with a rod 230 in the middle and two second connecting members 220 arranged on both sides of the rod 230 (see Figure 7b , and the thickness of the rod 230 is consistent with the thickness of the two second connecting members 220), which is not specifically required in this application, and it is only required to be arranged in pairs on both sides of the second connecting member 220, and can be adaptively selected according to actual needs. Among them, the first connecting member 210 and the second connecting member 220 can be connected by a pin. In order to cooperate with the pin, both have holes. Holes can be drilled on the first connecting member 210 and the second connecting member 220 first, and then welded to the housing 100, or both can be welded to the housing 100 separately and then drilled. The specific selection can be made according to needs.

[0063] like Figure 4b to Figure 7bAs shown, in the closed state, the first surrounding edge 130 and the second surrounding edge 170 are tightly attached to each other, so that the accommodating space is sealed, thereby reducing external pollution.

[0064] In order to facilitate production, the cross-sectional shapes of the first connecting member 210 and the second connecting member 220 are arranged uniformly. Furthermore, the first connecting member 210 and the second connecting member 220 are formed by metal stretching and cutting, which simplifies the production process and makes the production easier. After the metal is stretched, the whole is a columnar structure, and its cross section 240 has a minimum thickness, for example, Figure 7c , H is the minimum thickness of the cross section 240 , so in this embodiment, the first connecting member 210 and the second connecting member 220 formed after metal stretching and cutting have a minimum thickness respectively, preferably 3 to 14 mm.

[0065] The packaging box of the present application includes two outer shells 300, namely a first outer shell 310 and a second outer shell 320. The first shell 110 is hidden in the first outer shell 310, and the second shell 150 is hidden in the second outer shell 320. There are various ways to fix the first outer shell 310 and the first shell 110, such as gluing, welding, etc.

[0066] After the second shell 150 and the second outer shell 320 are fixed, the bottom wall of the second groove 160 is in contact with the bottom surface of the second outer shell 320. In order to increase the overall stability of the packaging box during the rotation of the hinge 200, the bottom surface of the second connecting member 220 is flush with the bottom wall of the second groove 160, so that the second connecting member 220 can also be in contact with the bottom surface of the second outer shell 320.

[0067] In this embodiment, the metal packaging box includes a container 400 for containing cosmetics disposed inside one of the shells and a makeup mirror 500 disposed inside the other shell. In the closed state, the makeup mirror 500 and the container 400 are disposed opposite to each other, wherein the makeup mirror 500 is fixed to the inner side of the first shell 110, and the container 400 is disposed in the second shell 150. Further, the container 400 is disposed in the second sink 160, and the makeup mirror 500 is disposed in the first sink 120. In order to achieve the fixation between the container 400 and the second sink 160, the two side walls of the container 400 are provided with a hollow and inwardly protruding first positioning portion 410, and the side wall of the second sink 160 is provided with an inwardly protruding second positioning portion 180, wherein in the assembled state, the second positioning portion 180 extends into the first positioning portion 410 so that the two are tightly matched, that is, the fixation of the two is achieved. In this embodiment, in order to facilitate recycling, the shell 100, the outer shell 300, the makeup mirror 500 and the container 400 are all made of metal, specifically aluminum.

[0068] In order to prevent the packaging box from being easily opened, the packaging box also includes a positioning member 190 and a spring buckle 191, wherein the spring buckle 191 is arranged in the space enclosed by the second surrounding edge 170 and the second outer shell 320, and is fixed to the bottom surface of the second shell 150. One end of the positioning member 190 is fixed to the back of the first surrounding edge 130, and the other end passes through the first surrounding edge 130 and the second surrounding edge 170 to cooperate with the spring buckle 191 to achieve the closed state of the packaging box. In this embodiment, the positioning member 190 and the spring buckle 191 can be fixed by riveting, laser welding or the like; and the shape of the positioning member 190 is not limited, for example, it can be a spherical buckle, a strip buckle, etc.

[0069] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0070] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
