Description

Technical Field

[0001] The present application relates to the field of cosmetic containers, and in particular to a cosmetic box. Background Art

[0002] Cosmetics are a type of product widely used to beautify, modify, or improve the appearance of the skin. Common types include facial makeup, eye makeup, and lip makeup. Their materials and chemical properties are diverse. In order to meet the packaging needs of different types of cosmetics, cosmetic containers play a vital role in the cosmetics production process.

[0003] Cosmetic containers typically consist of a lid and a box. The lid securely fits over the box, which is used to house cosmetics. The lid closes the cosmetics within the box to prevent leakage or contamination. To open and close the lid along the box, a connecting shaft is typically used to connect the box and lid, with other components such as torsion springs working together to enhance the user experience when opening the lid. When the user opens the lid along the box, the lid rotates along the connecting shaft to open it.

[0004] However, in actual application, when producing cosmetic containers, it is necessary to first install the rotating shaft and other components one by one on the cover and / or box body to complete the assembly of the cosmetic container. The operation is cumbersome and increases the production cost of the cosmetic container. At the same time, due to the special nature of cosmetic containers, after the cosmetics are used, the containers are usually recycled or discarded. Since there are many parts in the cosmetic containers, they are difficult to handle. Therefore, further improvement is needed. Utility Model Content

[0005] In order to reduce the number of parts required for the production of cosmetic containers, the present application provides a cosmetic box.

[0006] The present application provides a cosmetic box that adopts the following technical solution:

[0007] A cosmetic box comprises a cover and a box body, wherein the cover is fitted onto the box body, a connecting shaft is integrally formed on the cover, a snap-fitting groove is provided on the box body, the connecting shaft is rotatably connected to the snap-fitting groove, and the snap-fitting groove is used to limit the rotational position of the connecting shaft along the box body.

[0008] By adopting the above technical solution, the connecting shaft and the cover body are formed in one piece without the need for secondary assembly, which plays a positive guiding role in reducing the number of parts required in the production of cosmetic containers; at the same time, the position of the connecting shaft rotating along the box body is limited by the snap-fitting groove, so that the cover body can be stably opened and closed along the box body through the cooperation of the connecting shaft and the snap-fitting groove.

[0009] Preferably, the connecting shaft and the snap-fitting groove are transitionally matched.

[0010] By adopting the above technical solution, due to the transition fit between the connecting shaft and the snap-in groove, the connecting shaft can stay at any rotation angle when rotating along the snap-in groove, so that when the user opens the cover along the box body, the cover can be opened along the box body to any extent (within the stroke range), which plays a positive guiding role in improving the user's usage experience.

[0011] Preferably, the box body is provided with an elastic clamping portion, and when an external force is applied to the elastic clamping portion, the elastic clamping portion undergoes elastic deformation; when the connecting shaft is located in the clamping groove, the elastic clamping portion fits against the surface of the connecting shaft.

[0012] By adopting the above technical solution, the connecting shaft is stably clamped in the clamping groove through the clamping action of the elastic clamping part. At the same time, because the connecting shaft is in the clamping groove, the elastic clamping part fits with the surface of the connecting shaft, so that the connecting shaft is stably installed in the clamping groove, thereby further improving the stability of the rotating shaft when it can carry the cover body to rotate along the box body and stay at any rotation position, and at the same time, it also reduces the probability of loosening of the fit between the cover body and the box body due to unstable fit between the connecting shaft and the clamping groove; at the same time, during the assembly process of the cosmetic box, because the elastic clamping part can undergo elastic deformation, when the connecting shaft is installed in the clamping groove through the guiding action of the clamping groove, the elastic clamping part undergoes elastic deformation, so that the connecting shaft can be quickly installed in the clamping groove.

[0013] Preferably, a through groove is provided at the connection between the elastic clamping portion and the box body along the thickness direction of the elastic clamping portion.

[0014] By adopting the above technical solution, the stress at the connection between the elastic clamping part and the box body is released through the through groove, so that when the connecting shaft is installed in the clamping groove, the elastic clamping part can be elastically deformed in time, thereby reducing the high rigidity of the elastic clamping part, which makes it difficult to apply excessive force to the elastic clamping part during the installation of the connecting shaft in the clamping groove, thereby reducing the probability of irreversible deformation of the elastic clamping part or fracture along the box body.

[0015] Preferably, a connecting portion is integrally formed on the surface of the cover body facing the box body, the connecting shaft is integrally formed with the connecting portion, and reinforcing blocks are respectively provided at both ends of the connecting portion along the width direction, and the reinforcing blocks are integrally formed with the connecting shaft and the connecting portion.

[0016] By adopting the above technical solution, the connecting part and the cover body are integrally formed, which plays a positive guiding role in reducing the production cost of the cover body; at the same time, the reinforcing block can enhance the stability of the cooperation between the connecting shaft and the connecting part, thereby reducing the probability of the connecting shaft being subjected to excessive force when the user opens or closes the cover body, resulting in cracks or breaks along the connecting part.

[0017] Preferably, a limiting groove is provided on the connecting portion between the two reinforcing blocks, and the width of the limiting groove is adapted to the width of the elastic clamping portion.

[0018] By adopting the above technical solution, when the connecting shaft is located in the limiting groove, since the width of the limiting groove is adapted to the width of the elastic clip part, the installation position of the connecting part is limited by the limiting groove, thereby improving the stability of the cooperation between the connecting shaft and the elastic clip part, reducing the shaking of the cover along the box body when the user opens or closes the cover body, and playing a positive guiding role in improving the stability of the cover body when opening and closing along the box body.

[0019] Preferably, the box body is provided with a receiving groove along the side wall, the elastic clamping portion is arranged in the receiving groove, and the width of the receiving groove is adapted to the width of the connecting portion.

[0020] By adopting the above technical solution, the width of the accommodating groove is adapted to the width of the connecting portion, so that when the cover is installed on the box body through the connecting portion, the connection is relatively flat, which plays a positive guiding role in improving the appearance quality of the cosmetic box; at the same time, it further reduces the shaking of the cover when the user opens the cover along the box body, which is conducive to improving the stability of the cover when opening or closing along the box body.

[0021] Preferably, the elastic clamping portion is arranged to expand gradually from an end close to the cover to an end facing the lower surface of the box body.

[0022] By adopting the above technical solution, since the elastic clamping portion gradually expands from the end close to the cover body to the end facing the lower surface of the box body, it is beneficial to reduce the force required to force the elastic clamping portion to undergo elastic deformation. At the same time, during the assembly process of the box body and the cover body, the connecting shaft can be quickly installed in the limiting groove and fit with the elastic clamping portion through the guiding effect of the elastic clamping portion.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The connecting shaft and the cover are integrally formed without the need for secondary assembly, which plays a positive guiding role in reducing the number of parts required for the production of cosmetic containers;

[0025] 2. When the connecting shaft is located in the limiting groove, the elastic clamping portion fits against the surface of the connecting shaft, allowing the connecting shaft to be stably installed in the limiting groove, thereby reducing the probability of the cover and box body becoming loose due to unstable fit between the connecting shaft and the limiting groove;

[0026] 3. Through the cooperation of the limiting groove and the receiving groove, the connecting part can be stably clamped in the receiving groove, and the elastic clamping part can be stably clamped in the limiting groove, which is beneficial to improving the stability of the operator when opening or closing the cover along the box body, reducing the shaking of the cover when opening or closing, and playing a positive guiding role in improving the quality of the cosmetic box.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a cosmetic box 1. Figure 1-Figure 3 A cosmetic box 1 includes a cover 2 and a box body 3. The box body 3 is used to hold cosmetics. The cover 2 covers the box body 3, thereby reducing leakage of cosmetics in the box body 3 or pollution to the cosmetics.

[0035] Furthermore, a connecting shaft 4 is integrally formed on the cover body 2 , and a snap-fitting groove 5 is provided on the box body 3 . The connecting shaft 4 is rotatably connected to the snap-fitting groove 5 , and the snap-fitting groove 5 is used to limit the position of the connecting shaft 4 rotating along the box body 3 .

[0036] Therefore, compared with the method of using components such as a rotating shaft to connect the box body 3 and the cover body 2, in this embodiment, the connecting shaft 4 is integrally formed with the cover body 2 without the need for secondary assembly, which plays a positive guiding role in reducing the number of parts required for the production of cosmetic containers. At the same time, the position of the connecting shaft 4 rotating along the box body 3 is limited by the snap-fitting groove 5, so that the cover body 2 can be stably opened and closed along the box body 3 through the cooperation of the connecting shaft 4 and the snap-fitting groove 5.

[0037] At the same time, the box body 3 is provided with a receiving groove 11 along the side wall, and the engaging groove 5 is located on both sides of the receiving groove 11. The engaging groove 5 is formed by the surface of the box body 3 and the cover 2 covering each other, which is recessed downward along the thickness direction of the box body 3. The engaging groove 5 is open at the end of the box body 3 facing the cover 2 to facilitate the installation of the connecting shaft 4 in the engaging groove 5. When the connecting shaft 4 is installed along the engaging groove 5 and at the bottom of the engaging groove 5, the cover 2 can just cover the box body 3.

[0038] Correspondingly, the connecting shaft 4 and the snap-fitting groove 5 are transitionally fitted. The transition fitting described here is a conventional expression used in the mechanical field to express fitting tolerances and will not be explained here. Therefore, when the connecting shaft 4 is snap-fitted into the snap-fitting groove 5 at both ends along the length direction, when the user opens or closes the cover body 2 along the box body 3, the connecting shaft 4 can be rotated to any angle along the snap-fitting groove 5 and can remain at this angle when no external force is applied. When the connecting shaft 4 needs to be rotated along the snap-fitting groove 5 again, an external force needs to be applied to the connecting shaft 4 before the connecting shaft 4 can be driven to rotate along the snap-fitting groove 5 again.

[0039] Therefore, due to the transition fit between the connecting shaft 4 and the snap-fitting groove 5, the connecting shaft 4 can stay at any rotation angle when rotating along the snap-fitting groove 5, so that when the user opens the cover body 2 along the box body 3, the cover body 2 can be opened to any extent (within the stroke range) along the box body 3, which plays a positive guiding role in improving the user's usage experience.

[0040] Reference Figure 3 and Figure 4 An elastic clamping portion 6 is provided on the box body 3, and the elastic clamping portion 6 is provided in the accommodating groove 11. When an external force is applied to the elastic clamping portion 6, the elastic clamping portion 6 undergoes elastic deformation. When the connecting shaft 4 is located in the clamping groove 5, the elastic clamping portion 6 fits the surface of the connecting shaft 4.

[0041] Specifically, the elastic clamping portion 6 is integrally formed with the box body 3, and the elastic clamping portion 6 includes a support plate 61 and a clamping block 62. The fixed end of the support plate 61 is fixedly connected to the bottom of the accommodating groove 11 in the vertical direction. In this embodiment, there are two clamping blocks 62. The two clamping blocks 62 are located at the free ends of the support plate 61, and the two clamping blocks 62 are symmetrically arranged at both ends of the support plate 61 along the width direction along the geometric center of the support plate 61 along the width direction.

[0042] At the same time, the surface contour of the two clamping blocks 62 and the connecting shaft 4 is adapted to the contour of the connecting shaft 4, so that the two clamping blocks 62 can fit tightly with the connecting shaft 4 to reduce the gap between the two clamping blocks 62 and the connecting shaft 4, thereby reducing the probability of loosening of the fit between the cover body 2 and the box body 3 due to unstable fit between the connecting shaft 4 and the clamping groove 5, so that the connecting shaft 4 is stably installed in the clamping groove 5, thereby further improving the stability of the rotating shaft in carrying the cover body 2 to rotate along the box body 3 and stay at any rotation position.

[0043] In addition, during the assembly process of the cosmetic box 1, since the support plate 61 can undergo elastic deformation, when the connecting shaft 4 is installed in the clamping groove 5 through the guidance of the clamping groove 5, the support plate 61 undergoes elastic deformation, so as to facilitate the quick installation of the connecting shaft 4 in the clamping groove 5.

[0044] For the corresponding Figure 2 and Figure 3 A through groove 7 is provided at the connection between the elastic clamping portion 6 and the box body 3 along the thickness direction of the elastic clamping portion 6.

[0045] Specifically, the through groove 7 is formed by the connection between the two ends of the support plate 61 in the width direction and the two groove walls of the accommodating groove 11. The through groove 7 releases the stress at the connection between the support plate 61 and the box body 3, so that when the connecting shaft 4 is installed in the clamping groove 5, the support plate 61 can carry the two clamping blocks 62 to undergo elastic deformation in time, thereby reducing the high rigidity of the support plate 61, thereby reducing the probability of excessive force applied to the support plate 61 and / or the two clamping blocks 62 during the installation of the connecting shaft 4 in the clamping groove 5, resulting in irreversible deformation of the support plate 61 or breakage along the box body 3.

[0046] Please continue to refer to Figure 2 and Figure 3 The elastic clamping portion 6 is gradually expanded from one end close to the cover body 2 to one end facing the lower surface of the box body 3.

[0047] Specifically, the two clamping blocks 62 gradually expand along the free end of the support plate 61 toward the fixed end of the support plate 61 to form an inclined surface. The use of this inclined surface is conducive to reducing the force required to force the support plate 61 to undergo elastic deformation. At the same time, during the assembly process of the box body 3 and the box cover, the connecting shaft 4 can be quickly installed in the limiting groove 10 and fit tightly with the two clamping blocks 62 through the guiding effect of the two inclined clamping blocks 62.

[0048] Reference Figure 4 and Figure 5A connecting portion 8 is integrally formed on the surface of the cover body 2 facing the box body 3, the connecting shaft 4 is integrally formed with the connecting portion 8, and reinforcing blocks 9 are respectively provided at both ends of the connecting portion 8 along the width direction. The reinforcing blocks 9 are integrally formed with the connecting shaft 4 and the connecting portion 8.

[0049] Specifically, the connecting portion 8 is extended downward from the cover body 2 toward the lower surface of the box body 3, and the width of the connecting portion 8 is adapted to the width of the accommodating groove 11, so that when the cover body 2 is installed on the box body 3 through the cooperation of the connecting portion 8 and the connecting shaft 4, the connection is relatively flat, which plays a positive guiding role in improving the appearance quality of the cosmetic box 1. At the same time, it can also further reduce the shaking of the cover body 2 along the box body 3 when the user opens the cover body 2 along the box body 3, which is conducive to improving the stability of the cover body 2 when opening or closing along the box body 3.

[0050] Correspondingly, the reinforcing block 9 can enhance the stability of the cooperation between the connecting shaft 4 and the connecting part 8, thereby reducing the probability that the connecting shaft 4 will be subjected to excessive force when the user opens or closes the cover body 2, resulting in cracks or breaks in the connecting shaft 4 along the connecting part 8.

[0051] At the same time, a limiting groove 10 is provided on the connecting portion 8 between the two reinforcing blocks 9. The width of the limiting groove 10 is adapted to the width of the elastic clamping portion 6, that is, the width of the limiting groove 10 is adapted to the width of the support plate 61. When the connecting shaft 4 is located in the limiting groove 10, the width of the limiting groove 10 is adapted to the width of the support plate 61. The limiting groove 10 limits the installation position of the connecting portion 8, thereby improving the stability of the cooperation between the connecting shaft 4 and the support plate 61, reducing the shaking of the cover body 2 along the box body 3 when the user opens or closes the cover body 2, and playing a positive guiding role in improving the stability of the cover body 2 when opening and closing along the box body 3.

[0052] Reference Figure 2 or Figure 4 A buckle 12 is integrally formed on the box body 3 at one end away from the accommodating groove 11. When the cover body 2 is covered on the box body 3, the cover body 2 is engaged with the box body 3 through the buckle 12, so that the cover body 2 is tightly covered on the box body 3. The user needs to apply external force to the box body 3 or the cover body 2 to release the lock between the cover body 2 and the box body 3, so that the user can open or close the cover body 2 along the box body 3. The mechanical structure is simple.

[0053] The implementation principle of a cosmetic box 1 in the embodiment of the present application is as follows: when assembling the cosmetic box 1, the connecting shaft 4 is first installed in the clamping groove 5. When the two ends of the connecting shaft 4 along the length direction are located at the bottom of the clamping groove 5, the cover body 2 can just cover the box body 3 to reduce the amount of cosmetic leakage. At the same time, due to the transition fit between the clamping groove 5 and the connecting shaft 4, and the snap-fitting effect of the two clamping blocks 62, the rotating shaft can be rotated to any angle, and when no external force is applied, the rotating shaft can always stay here, so that the cover body 2 can be opened at any angle along the box body 3, and when no external force is applied, the angle of the cover body 2 opened along the box body 3 remains unchanged. The user needs to apply external force to the cover body 2 again to make the rotating shaft rotate along the clamping groove 5 to achieve the purpose of smoothly opening or closing the cover body 2 along the shell, and the cover body 2 can hover at any position, which is highly practical.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
