Description

Technical Field

[0001] This utility model relates to the field of cosmetic tools technology, and in particular to a flip-top cosmetic box. Background Technology

[0002] Currently, the lid of a cosmetic case is usually opened or closed by a hinge. When closing the lid, a magnetic component or a latching structure is required between the lid and the base to prevent the lid from opening. With repeated use, the magnetic component may lose its magnetic force, and the latching structure may break, causing the lid to open accidentally, affecting the stability of use and the user experience.

[0003] In addition, the base is usually equipped with an inner liner box for holding the powder compact. When the lid is closed, the upper surface of the powder compact is likely to touch the lid, which is not only unhygienic and wastes powder, but also dirties the mirror on the inner surface of the lid, giving users a poor user experience. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the purposes of this utility model is to provide a flip-top cosmetic box that can prevent accidental opening of the cover and avoid the cover from scratching cosmetics.

The base includes a fixed seat and a movable seat rotatably disposed on the fixed seat about a vertical axis. The inner liner is vertically disposed on the fixed seat. A spiral lifting mechanism is provided between the movable seat and the inner liner to drive the inner liner to move up and down relative to the fixed seat and then fix it. The cover is rotatably disposed on the fixed seat about a horizontal axis. A linkage mechanism is provided between the inner liner and the cover. The linkage mechanism drives the cover to open when the inner liner rises and drives the cover to close when the inner liner falls.

[0006] The flip-top cosmetic box according to the embodiments of the present utility model has at least the following beneficial effects:

[0007] The flip-top cosmetic case with the above structure rotates the movable base relative to the fixed base when the lid needs to be opened. The spiral lifting mechanism then raises and fixes the inner liner box. During this process, the linkage mechanism uses the rising motion of the inner liner box to rotate and open the lid. When the lid needs to be closed, the movable base rotates in the opposite direction relative to the fixed base. The spiral lifting mechanism then lowers and fixes the inner liner box. The linkage mechanism uses the falling motion of the inner liner box to rotate and close the lid. This design prevents accidental opening of the lid and avoids the lid scratching cosmetics when closing.

[0008] In some embodiments of this utility model, when the face cover is closed, a height space for placing cosmetic tools is formed between the upper end of the inner liner box and the face cover.

[0009] In some embodiments of this utility model, the fixed seat has a first annular wall arranged circumferentially around the vertical axis, and the movable seat has a second annular wall concentrically arranged with the first annular wall.

[0030] Reference Figures 1 to 4This utility model discloses a flip-top cosmetic box, comprising: a base 100, a cover 200, and an inner liner box 300. The base 100 includes a fixed seat 110 and a movable seat 120 rotatably disposed on the fixed seat 110 about a vertical axis. The inner liner box 300 is vertically and vertically disposed on the fixed seat 110. A spiral lifting mechanism 400 is provided between the movable seat 120 and the inner liner box 300 to drive the inner liner box 300 to move up and down relative to the fixed seat 110 and then be fixed. The cover 200 is rotatably disposed on the fixed seat 110 about a horizontal axis. A linkage mechanism 500 is provided between the inner liner box 300 and the cover 200. The linkage mechanism 500 drives the cover 200 to open when the inner liner box 300 rises and drives the cover 200 to close when the inner liner box 300 falls.

[0031] When the flip-top cosmetic case with the above structure needs to open the lid 200, the movable base 120 rotates relative to the fixed base 110. The spiral lifting mechanism 400 lifts the inner liner box 300 and fixes it. During this process, the linkage mechanism 500 uses the upward movement of the inner liner box 300 to rotate and open the lid 200. When the lid 200 needs to be closed, the movable base 120 rotates in the opposite direction relative to the fixed base 110. The spiral lifting mechanism 400 lowers the inner liner box 300 and fixes it. The linkage mechanism 500 uses the downward movement of the inner liner box 300 to rotate and close the lid 200. This not only prevents accidental opening of the lid 200 but also avoids the lid 200 scratching cosmetics when closing.

[0032] It should be noted that as the lid 200 slowly opens, the spiral lifting mechanism 400 drives the inner liner box 300 to rise slowly, creating a visual effect that the cosmetics in the inner liner box 300 are lifted, thus enhancing the sense of ritual in using the product.

[0033] See Figure 2 and Figure 3 In some embodiments of this utility model, when the face cover 200 is closed, a height space for placing makeup tools is formed between the upper end of the inner liner box 300 and the face cover 200. It should be noted that when the face cover 200 is closed, the inner liner box 300 is at its lowest position relative to the fixing base 110. At this time, there is a certain height space between the upper end of the inner liner box 300 and the face cover 200, allowing the user to store makeup tools within this space. For example, when the inner liner box 300 is used to hold a powder compact, the height space is used to place a powder puff. When the cover is opened, the inner liner box 300 raises the powder puff for the user to pick up directly, making it very convenient to use and helping to avoid losing the powder puff, eliminating the need to carry it separately.

[0034] See Figure 2 and Figure 4In some embodiments of this utility model, in order to enable the movable seat 120 to rotate relative to the fixed seat 110 around the vertical axis, the fixed seat 110 has a first annular wall 111 arranged circumferentially around the vertical axis, and the movable seat 120 has a second annular wall 121 concentrically arranged with the first annular wall 111. One of the second annular wall 121 and the first annular wall 111 has an annular protrusion 122 on its peripheral wall, and the other has an annular groove that cooperates with the annular protrusion 122.

[0035] See Figure 4 In some embodiments of this utility model, the first annular wall 111 is sleeved on the outside of the second annular wall 121, the annular groove is formed on the inner peripheral wall of the first annular wall 111, the annular protrusion 122 is formed on the outer peripheral wall of the second annular wall 121, the fixing seat 110 is also provided with an annular plate 113 located on the inner side of the second annular wall 121, the inner liner box 300 is located inside the annular plate 113, and the spiral lifting mechanism 400 includes a spiral guide groove 410 formed on the outer peripheral wall of the second annular wall 121, a vertical guide groove 420 formed on the annular plate 113, and a guide post 430 provided on the outer peripheral wall of the inner liner box 300. The guide post 430 passes through the vertical guide groove 420 and is inserted into the spiral guide groove 410. Understandably, when the movable seat 120 rotates relative to the fixed seat 110, the guide column 430 moves from the lower end to the upper end of the spiral guide groove 410 or from the upper end to the lower end of the spiral guide groove 410. Simultaneously, the guide column 430 is limited by the vertical guide groove 420 and can only move up and down along the vertical guide groove 420, thereby driving the inner liner box 300 to move up and down relative to the annular plate 113. This spiral lifting mechanism 400 has a very simple structure, is easy to manufacture, and is inexpensive. It should be noted that the movable seat 120 and the fixed seat 110 are generally injection molded, therefore the vertical guide column and the spiral guide groove 410 are very easy to manufacture.

[0036] In addition, when assembling the base 100, the movable seat 120 is inserted upward into the fixed seat 110, and the first annular wall 111 is inserted downward relative to the second annular wall 121. Both the first annular wall 111 and the second annular wall 121 undergo slight elastic deformation in the radial direction to complete the connection between the annular protrusion 122 and the annular groove.

[0037] See Figure 4In some embodiments of this utility model, in order to improve the stability of the movable seat 120 relative to the fixed seat 110 and prevent the movable seat 120 from tilting or jamming, the two spiral guide grooves 410 are arranged symmetrically about the center of the base 100, the two guide posts 430 are disposed opposite to each other on the outer peripheral wall of the inner liner box 300 and correspond one-to-one with the two spiral guide grooves 410, and the two vertical guide grooves 420 are disposed opposite to each other on the annular plate 113 and correspond one-to-one with the two guide posts 430.

[0038] See Figure 4 In some embodiments of this utility model, the upper end of the spiral guide groove 410 is provided with a first positioning groove 411 for elastically engaging the guide post 430. When the cover 200 is at its maximum opening angle, the guide post 430 is engaged in the first positioning groove 411 to prevent accidental contact that would cause the cover 200 to rotate in the closing direction.

[0039] See Figure 4 In some embodiments of this utility model, the lower end of the spiral guide groove 410 is provided with a second positioning groove 412 for elastically engaging the guide post 430. When the cover 200 is in a fully closed state, the guide post 430 is engaged in the second positioning groove 412 to prevent accidental contact that could cause the cover 200 to open.

[0040] See Figure 4 and Figure 5 In some embodiments of this utility model, the annular plate 113 abuts against the inner peripheral wall of the first annular wall 111, guiding the rotation of the movable seat 120. The inner liner box 300 includes a circular base plate 310 and an annular member 320 extending upward along the outer peripheral wall of the circular base plate 310. The inner liner box 300 forms an upward-opening cavity for placing cosmetics. The guide post 430 is formed on the outer peripheral wall of the annular member 320. A portion of the outer peripheral edge of the circular base plate 310 and the annular member 320 are provided with an arc-shaped through-hole groove 311 opposite to the guide post 430. It can be imagined that when assembling the movable seat 120 and the fixed seat 110, due to the presence of the arc-shaped through-hole groove 311, the position of the annular member 320 corresponding to the guide post 430 can undergo inward radial deformation, allowing the guide post 430 to smoothly enter the spiral guide groove 410, facilitating assembly.

[0041] See Figure 1 and Figure 4In some embodiments of this utility model, one side of the cover 200 is rotatably connected to the fixed base 110 via a horizontally arranged first pivot 210. The inner liner box 300 has an upwardly extending bracket 330 on the side near the first pivot 210. The linkage mechanism 500 includes a connecting arm 510 formed on the cover 200 and extending away from the inner sidewall of the cover 200. The connecting arm 510 has a long guide hole 520 through it along its length. The bracket 330 is provided with a rod 530 horizontally passing through the long guide hole 520. When the inner liner box 300 moves up and down, the rod 530 reciprocates in the long guide hole 520 to drive the cover 200 to rotate around the first pivot 210. Understandably, when the inner liner box 300 rises, the rod 530 moves within the elongated guide hole 520 to the end of the guide hole 520 furthest from the cover 200. At this time, the cover 200 is subjected to an upward flipping force and rotates around the first pivot 210 to open. Similarly, when the inner liner box 300 descends, the rod 530 moves within the elongated guide hole 520 to the end of the guide hole 520 closest to the cover 200. At this time, the cover 200 is subjected to a downward flipping force and rotates around the first pivot 210 to close. The above linkage mechanism 500 has a very simple structure and avoids the need for additional assembly of parts.

[0042] See Figure 1 and Figure 4 In some embodiments of this utility model, the bracket 330 is provided with two opposing vertical ribs 331, the upper end of the vertical ribs 331 is provided with bushings 332, and an upward-opening relief groove 333 is formed between the two vertical ribs 331. The connecting arm 510 passes through the relief groove 333, and the rod 530 passes through the two bushings 332. The two vertical ribs 331 restrict the circumferential displacement of the connecting arm 510 along the rod 530, thereby improving the stability of the cover 200 when it is opened and closed.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
