[0031] A packaging box for a coating material body provided in an embodiment of the present application is described below in conjunction with the accompanying drawings. The packaging box for the coating material body of the present application is particularly suitable for a scenario in which a material carrier tray 10 is replaced.

[0032] See also Figure 1-Figure 3 The packaging box of a coating material provided in an embodiment of the present application includes a base 30, a first inner sleeve 20 and a second inner sleeve 21, wherein the first inner sleeve 20 and the second inner sleeve 21 are connected by an integrally formed rotatable connecting portion 22, the second inner sleeve 21 is fixedly disposed in the base 30, the second inner sleeve 21 is used to accommodate a material loading tray 10, and the first inner sleeve 20 is used to be engaged with the second inner sleeve 21 to fix the material loading tray 10. Through the design of the first inner sleeve 20, the second inner sleeve 21 and the rotatable connecting portion 22, the locking force between the material loading tray 10 and the base 30 is reduced, the difficulty of replacing the material loading tray 10 is reduced, and the efficiency of replacing the material loading tray is improved.

[0033] It can be understood that the coating material packaging box is a component specially designed for the interior of the coating material container, which has the functions of loading the coating material, protecting the coating material from contamination, providing structural support, and facilitating the use of the product. In the embodiment of the present application, the coating material can be in the form of liquid, powder, paste or cream. On the other hand, the coating material can be a cosmetic or skin care product.

[0034] Specifically, a packaging box for a coating material body includes an inner sleeve assembly, which includes a first inner sleeve 20, a second inner sleeve 21 and an integrally formed rotatable connecting portion 22, that is, the first inner sleeve 20 and the second inner sleeve 21 are rotatably connected. When the packaging box is opened, the first inner sleeve 20 is exposed to the user's field of vision, and when the packaging box is closed, the inner sleeve assembly is not exposed to the user's field of vision.

[0035] Specifically, the loading tray 10 is used to store the coating material body, the base 30 is used to accommodate the second inner sleeve 21 and the loading tray 10, the base 30 is detachably connected to the loading tray 10, the first inner sleeve 20 is arranged on the side of the second inner sleeve 21 away from the base 30, and the first inner sleeve 20 and the second inner sleeve 21 are rectangular plastic rings.

[0036] In one embodiment, when the first inner sleeve 20 and the second inner sleeve 21 are in close contact, the height of the inner sleeve assembly is less than the height of the base 30 .

[0037] Specifically, the second inner sleeve 21 includes a step mounting portion, the base 30 includes a cavity corresponding to the second inner sleeve 21 , and the step mounting portion is in contact with the base 30 .

[0038] Specifically, when the first inner sleeve 20 and the second inner sleeve 21 are not engaged, the first inner sleeve 20 and the second inner sleeve 21 are in a non-interference fit. In this way, there is a gap between the first inner sleeve 20 and the second inner sleeve 21, which reduces the friction force of the material loading tray 10 during the assembly process, reduces the difficulty of assembling and disassembling the material loading tray 10, and prolongs the service life of the packaging box.

[0039] Specifically, the second inner sleeve 21 is non-interference fit with the material loading tray 10. In one possible implementation, the outer edge of the material loading tray 10 can abut against the second inner sleeve 21. In another possible implementation, there is a gap between the outer edge of the material loading tray 10 and the second inner sleeve 21.

[0040] Specifically, when the first inner sleeve 20 and the second inner sleeve 21 are buckled together, the first inner sleeve 20 and the second inner sleeve 21 are fitted together near the rotatable connecting portion 22 , and a gap is provided between the first inner sleeve 20 and the second inner sleeve 21 away from the rotatable connecting portion 22 .

[0041] Specifically, the first inner sleeve 20, the second inner sleeve 21 and the rotatable connecting part 22 are integrally formed. In a possible forming method, the first inner sleeve 20, the second inner sleeve 21 and the rotatable connecting part 22 are formed by injection molding through a set of molds. Specifically, in the set of molds, the injection molding machine uses a one-time injection molding process, and after the mold is opened by injection molding of molten plastic particles, the first inner sleeve 20, the second inner sleeve 21 and the rotatable connecting part 22 that are connected to each other can be obtained. In this way, the overall structure of the inner sleeve assembly is more stable, loosening, falling off or deformation between components is avoided, the overall service life of the packaging box is improved, and the assembly process of the packaging box is simplified, the number of parts is reduced, the assembly cost is reduced, and the production efficiency is improved.

[0042] Specifically, the first inner sleeve 20, the second inner sleeve 21 and the rotatable connecting portion 22 are made of the same material, and the inner sleeve assembly is formed by injection molding the same material in the packaging box.

[0043] Specifically, the average thickness of the rotatable connecting portion 22 is smaller than the thickness of the first inner sleeve 20 and / or the second inner sleeve 21 , and the hardness of the rotatable connecting portion 22 is smaller than the hardness of the first inner sleeve 20 and / or the second inner sleeve 21 .

[0044] Optionally, the materials of the first inner sleeve 20, the second inner sleeve 21 and the rotatable connecting part 22 can be polypropylene PP, polyamide nylon, polyethylene PE, polycarbonate PC, etc.

[0045] In one embodiment, the first inner sleeve 20, the second inner sleeve 21 and the integrally formed rotatable connecting portion 22 are integrally formed by two-color injection molding.

[0046] Furthermore, the packaging box further includes an outer cover 40, which is used to cover the base 30, and the outer cover 40 is rotatably connected to the base 30. The rotatable connection between the outer cover 40 and the base 30 can make it easy for the user to take the coating material and can also ensure good sealing between the outer cover 40 and the base 30, effectively preventing the coating material in the packaging box from being affected by the external environment.

[0047] Specifically, when the outer cover 40 is covered with the base 30, the package of the coating material body is in an open state; when the outer cover 40 is separated from the base 30, the package of the coating material body is in a closed state. When the package of the coating material body is in an open state, if the loading tray 10 is disposed in the second inner sleeve 21, the loading tray 10 is exposed to the user's field of vision, and the user can use the coating material body.

[0048] Specifically, the outer cover 40 includes a first plane close to the base 30 , the base 30 includes a second plane close to the outer cover 40 , and the angle between the first plane and the second plane is 0°-90°.

[0049] Specifically, the packaging box of the coating material body further includes a hinge assembly 50 , and the outer cover 40 and the base 30 are hingedly connected via the hinge assembly 50 .

[0050] In one embodiment, the hinge assembly 50 is a metal hinge assembly, and the hinge assembly 50 further includes a limiting mechanism to limit the rotation range of the outer cover 40 .

[0051] Specifically, the rotation axis of the first inner sleeve 20 and the second inner sleeve 21 is in the first direction, the rotation axis of the base 30 and the outer cover 40 is in the second direction, and the first direction intersects with the second direction. In this way, the rotation axes of the base 30 and the outer cover 40 and the first inner sleeve 20 and the second inner sleeve 21 can move relatively independently without interfering with each other, thereby making full use of the space of the packaging box and improving the design flexibility and access efficiency of the packaging box.

[0052] In the embodiment of the present specification, after the base 30 is separated from the outer cover 40, the first inner sleeve 20 and the second inner sleeve 21 are separated, and then the first loading tray is taken out. During this process, the first inner sleeve 20 and the outer cover 40 do not interfere with each other. The first loading tray is the loading tray to be replaced, and the second loading tray is the loading tray to be replaced.

[0053] Preferably, the first direction is perpendicular to the second direction, thus further improving the stability and independence of the overall structure of the inner sleeve assembly.

[0054] In another embodiment, the first direction is parallel to the second direction, that is, the rotatable connection portion 22 is disposed on a side of the second inner sleeve 21 that is disposed opposite to the hinge assembly 50 .

[0055] Specifically, the length of the first inner sleeve 20 along the first direction is smaller than the length of the second inner sleeve 21 along the first direction, and the length of the first inner sleeve 20 along the second direction is smaller than the length of the second inner sleeve 21 along the second direction. In this way, the first inner sleeve 20 can be accommodated in the second inner sleeve 21, and during the rotation of the first inner sleeve 20, the friction between the first inner sleeve 20 and the second inner sleeve 21 is reduced, thereby increasing the service life of the first inner sleeve 20 and the second inner sleeve 21.

[0056] Specifically, the difference between the length of the first inner sleeve 20 along the first direction and the length of the second inner sleeve 21 along the first direction is smaller than the difference between the length of the first inner sleeve 20 along the second direction and the length of the second inner sleeve 21 along the second direction.

[0057] Furthermore, the rotation angle of the first inner sleeve 20 and the second inner sleeve 21 is 0°-120°. In this way, the user can select a suitable angle according to his / her own needs, which is convenient for taking and placing the coating material body, thereby improving the flexibility and convenience of use.

[0058] Specifically, the rotation angle of the first inner sleeve 20 and the second inner sleeve 21 is selected based on user needs. When the user can take out the first loading tray and / or put in the second loading tray, the first inner sleeve 20 and the second inner sleeve 21 can be 20°, 40°, 60°, 90°, etc.

[0059] Furthermore, a handheld component is further included, which is arranged on the first inner sleeve 20, and the handheld component is arranged on a side away from the integrally formed rotatable connecting portion 22, and the handheld component is rotatably connected to the first inner sleeve 20; or the handheld component is fixedly connected to the first inner sleeve 20. By arranging the handheld component on a side away from the rotatable connecting portion 22, the user can more easily open the first inner sleeve 20 to replace the material loading tray 10, and the handheld component can also strengthen the visual focus in the packaging box, thereby improving the functionality and overall aesthetics of the packaging box.

[0060] In one embodiment, when the hand-held component is rotatably connected to the first inner sleeve 20, the angle between the plane where the hand-held component is located and the plane where the first inner sleeve 20 is located is 0°-90°. When the angle between the plane where the hand-held component is located and the plane where the first inner sleeve 20 is located is 0°, the hand-held component is arranged along the outer edge of the side away from the rotatable connection part 22 with a gap between the outer cover 40 and the base 30; when the angle between the plane where the hand-held component is located and the plane where the first inner sleeve 20 is located is 90°, the height of the hand-held component is less than or equal to the relative distance between the base 30 and the outer cover 40.

[0061] In another embodiment, when the handheld component is fixedly connected to the first inner sleeve 20, the handheld component is protruding, and the height of the handheld component is smaller than the relative distance between the base 30 and the outer cover 40, that is, the handheld component does not contact the outer cover.

[0062] Specifically, the handheld component is a side guard mechanism, and the side guard mechanism is fixedly connected to the first inner sleeve 20 .

[0063] Specifically, in a possible implementation, the first inner sleeve 20 includes a frosted area, which is disposed on a side away from the integrally formed rotatable connection portion 22. When the user contacts the frosted area, the friction between the hand and the first inner sleeve 20 is increased, and the user can open the first inner sleeve 20 more easily.

[0064] Specifically, the frosted area is arranged on the upper surface of the first inner sleeve 20 away from the rotatable connecting portion 22, the friction coefficient of the frosted area is greater than the friction coefficient of the non-frosted area, and the shape of the frosted area can be customized based on user needs.

[0065] Optionally, the frosted area may be provided by sandblasting, chemical frosting or mechanical frosting.

[0066] Furthermore, a display element 60 is further included, and the display element 60 is arranged between the outer cover 40 and the loading tray 10, and the display element 60 is connected to the outer cover 40. By arranging the display element 60 between the outer cover 40 and the loading tray 10, the appearance and characteristics of the product can be better displayed, and the display effect of the packaging box can be increased.

[0067] Specifically, in the embodiment of the present specification, the display element 60 is a lens, and a receiving groove is provided in the outer cover 40, the receiving groove is used to receive the lens, the area of ​​the lens is smaller than the area of ​​the outer cover 40, and the receiving groove is provided with a plurality of fixing mechanisms, which are directly attached to the lens.

[0068] Optionally, the lens may be detachably connected to the outer cover 40 , or the lens may be fixedly connected to the outer cover 40 .

[0069] The following describes the process of replacing the loading tray of the coated package box in combination with specific application scenarios, which includes:

[0070] First, open the coating material packaging box, the outer cover 40 and the base 30 are set at an angle, and then open the first inner sleeve 20, the first inner sleeve 20 and the second inner sleeve 21 are set at an angle;

[0071] Then, the user takes out the first material loading tray from the second inner sleeve 21 and puts the second material loading tray into the second inner sleeve 21;

[0072] Finally, the first inner sleeve 20 is buckled to fit the first inner sleeve 20 and the second inner sleeve 21, thereby fixing the second loading tray and the second inner sleeve 21. The user can choose whether to close the coating material body packaging box based on their own needs.

[0073] That is, users can Figure 8 , Figure 6 , Figure 7 , Figure 8 The operation sequence is to complete the action of taking out the first loading tray and replacing the second loading tray.
