[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0044] To address the shortcomings of existing technologies, this invention addresses these issues by placing the rotating connection point on the side wall of the chassis assembly, with the two adjacent side walls arranged parallel to the rotating connection point. This ensures that the user holds the device on the relatively parallel side walls, preventing the user's hand from being guided to the rotating connection point by the sides of the chassis assembly. Consequently, it prevents the first cover from pinching the user when opening and closing relative to the chassis assembly, reducing the probability of user injury and improving user safety.

[0045] Referring to Figures 1 to 9, this embodiment provides a packaging box for a coating, including: a first cover 1; a second cover 2, the first cover 1 being rotatable relative to the second cover 2; a chassis assembly, the chassis assembly being engaged with the first cover 1, the first cover 1 being rotatable relative to the chassis assembly until the first cover 1 disengages from the chassis assembly; the chassis assembly having a rotatable connection position, the second cover 2 being pivotally connected to the chassis assembly through the rotatable connection position; the rotatable connection position being disposed on the side wall of the chassis assembly, and the two side walls adjacent to the side wall where the rotatable connection position is located being arranged parallel to each other; the first cover 1 being able to drive the second cover 2 to rotate relative to the chassis assembly until the first cover 1 opens relative to the chassis assembly.

[0046] In this embodiment, the shape of the packaging box for the coating is not limited, as long as the side wall of the packaging box does not guide the user's hand, i.e., it does not guide the user's hand to the rotating connection position. The packaging box is a non-circular, multi-morphic structure, and it is necessary to ensure that the two side walls adjacent to the side wall where the rotating connection position is located are set parallel to each other.

[0047] Preferably, the cross-sectional shape of the packaging box for the coating is quadrilateral, which can be either rectangular or square.

[0048] In this embodiment, the first cover 1 is the outer cover of the packaging box of the coating material, so the cross-section of the first cover 1 is quadrilateral. The chassis assembly is fastened to the first cover 1, and the cross-section of the chassis assembly is also quadrilateral.

[0049] In this embodiment, the first cover 1 can rotate around the second cover 2. To ensure the smoothness of the rotation of the first cover 1 relative to the second cover 2, and to avoid excessive gaps between the first cover 1 and the second cover 2 during the rotation of the first cover 1 relative to the second cover 2, the inner wall of the first cover 1 is cylindrical, and the second cover 2 has a cylindrical structure.

[0050] It should be noted that in this embodiment, by setting the rotating connection position on the side wall of the chassis assembly and setting the two side walls adjacent to the side wall where the rotating connection position is located parallel, it can be ensured that the user holds on the relatively parallel side walls, avoiding the user's hand being guided to the rotating connection position by the two sides of the chassis assembly. This prevents the first cover 1 from pinching the user when opening and closing relative to the chassis assembly, reduces the probability of the user being pinched, improves user safety, and thus improves the user experience.

[0051] In this embodiment, the chassis assembly has a second receiving cavity for holding a material. The material is a block structure, specifically a powder-type coating material. By placing the powder-type coating material in the packaging box of the coating material, the sealing effect of the powder-type coating material can be improved, reducing the occurrence of cracking or deterioration of the powder-type material due to long-term contact with the external environment.

[0052] In some possible embodiments, one of the second cover 2 and the chassis assembly is provided with a pivot connection portion 21, and the other is provided with a notch 51 that mates with the pivot connection portion 21. By providing the pivot connection portion 21 and the notch 51 that mate with each other, it can be ensured that the pivot connection portion 21 is accommodated in the notch 51, and the pivot connection portion 21 is prevented from protruding. That is, when the first cover 1 is fastened to the chassis assembly, the pivot connection portion 21 is completely accommodated in the notch 51, thereby ensuring the aesthetics of the packaging box of the coating material.

[0053] In some possible embodiments, a notch is provided on the chassis assembly, and a pivot connection 21 is provided on the second cover 2. Specifically, when the chassis assembly includes a material tray 4 and a chassis 5, notches are provided at corresponding positions on both the material tray 4 and the chassis 5. If a notch is provided only on the chassis 5, it is easy for the pivot connection 21 on the second cover 2 to interfere with the material tray 4, causing the second cover 2 to be unable to rotate relative to the chassis assembly. Alternatively, the size of the chassis 5 may be increased to avoid interference between the second cover 2 and the material tray 4. This would increase the overall size of the packaging box of the coating material, increase the manufacturing cost, and reduce the user experience. Therefore, by providing notches on both the material tray 4 and the chassis 5, it is possible to avoid increasing the overall size of the packaging box of the coating material, thereby avoiding increasing the manufacturing cost and ensuring the user experience.

[0054] In some other possible embodiments, the second cover 2 is provided with a notch, and the chassis assembly is provided with a pivot connection 21.

[0055] In this embodiment, when a notch is provided on the chassis assembly and a pivot connection part 21 is provided on the second cover 2, the pivot connection part 21 protrudes from the side wall of the second cover 2 and a through hole is provided on the pivot connection part 21. The through hole contains a rotating shaft. After the rotating shaft is installed in the through hole, both ends of the rotating shaft protrude from both ends of the through hole. Mounting holes are provided at both opposite ends of the notch. Both ends of the rotating shaft extend into the mounting holes to realize the rotational connection between the second cover 2 and the chassis assembly.

[0056] Specifically, the length of the rotating shaft is slightly greater than the distance between the two relatively set mounting holes. This ensures that the rotating shaft will not fall off after being installed in the mounting holes, thereby ensuring the stability of the coating material packaging box during opening or closing and guaranteeing the user experience.

[0057] In some possible embodiments, the rotatable connection can be located on the side wall of the chassis assembly, and the specific location is not limited.

[0058] In this embodiment, the rotating connection position is located in the middle area of ​​the side wall of the chassis assembly. By setting it in the middle area, the symmetrical arrangement of the coating material packaging box can be ensured, improving its aesthetics. At the same time, if the rotating connection position is not located in the middle area, in order to ensure that the second cover 2 is fastened to the chassis assembly, there will be space on the side of the chassis assembly away from the rotating connection position that does not fit with the second cover 2, resulting in wasted space. This will also increase the size of the chassis assembly, thereby increasing the manufacturing cost of the coating material packaging box and increasing the overall size of the coating material packaging box, thus reducing the user's experience.

[0059] In this embodiment, the structures on both sides of the rotating connection position on the chassis assembly are symmetrically arranged, which improves its aesthetics, optimizes the overall size, reduces manufacturing costs, and ensures the user's experience.

[0060] In this embodiment, a lens structure is provided on the side of the second cover 2 near the material tray 4, and the lens structure is bonded to the second cover 2.

[0061] Specifically, the lens structure is a circular structure adapted to the second receiving cavity, and the outer diameter of the lens structure is smaller than the inner diameter of the second receiving cavity.

[0062] In some possible embodiments, a sealing ring 6 is provided between the second cover 2 and the chassis assembly; the sealing ring 6 and the second cover 2 are integrally molded using two-color injection molding; and / or, the sealing ring 6 and the chassis assembly are integrally molded using two-color injection molding. By providing a sealing ring 6 between the second cover 2 and the chassis assembly, it can be ensured that both sides of the sealing ring 6 are sealed and fitted to the second cover 2 and the chassis assembly respectively, ensuring that there are no gaps between the second cover 2 and the chassis assembly. This can increase the sealing performance between the second cover 2 and the chassis assembly, prevent dirt from entering the packaging box of the coating material, and also prevent the material inside the packaging box of the coating material from spilling to the outside, thereby avoiding waste of the material inside the packaging box of the coating material.

[0063] In this embodiment, by setting the sealing ring 6, the coating material inside the chassis assembly can also be kept in a sealed environment, preventing the coating material from contacting the external environment and causing it to dry and crack or deteriorate. This improves the sealing effect of the coating material of the powder compact and reduces the risk of the powder compact material drying and cracking or deteriorating due to long-term contact with the external environment.

[0064] In this embodiment, a sealing ring 6, manufactured by two-color injection molding, is located on the lower edge of the second cover 2. The sealing ring 6 is a part of the second cover 2, which is injection molded using a set of molds. The molds are used in two separate injection molding processes on an injection molding machine, using a harder material in the first injection and a softer material in the second. The harder material is used to form the main body of the second cover 2, while the softer material is used to produce the sealing ring 6.

[0065] In some possible embodiments, when the sealing ring 6 is integrally formed with the second cover 2, the second cover 2 is provided with a first annular groove, and a portion of the sealing ring 6 is accommodated in the first annular groove; and / or, when the sealing ring 6 is integrally formed with the chassis assembly, the chassis assembly is provided with a second annular groove, and a portion of the sealing ring 6 is accommodated in the second annular groove. By providing an annular groove for accommodating the sealing ring 6, the connection area of ​​the sealing ring 6 can be increased, preventing the sealing ring 6 from falling off and improving the stability of the connection of the sealing ring 6.

[0066] In this embodiment, the sealing ring 6 and the second cover 2 are integrally formed. The second cover 2 is provided with a first annular groove, and part of the sealing ring 6 is accommodated in the first annular groove. Compared with the prior art, the connection surface between the sealing ring 6 and the second cover 2 in this embodiment is increased from one to three, thereby increasing the connection area and thus increasing the connection strength and ensuring the stability of the connection of the sealing ring 6.

[0067] In some other possible embodiments, the sealing ring 6 is integrally formed with the second cover 2. The second cover 2 is provided with a first annular groove, and part of the sealing ring 6 is accommodated in the first annular groove. The material tray 4 of the chassis assembly is provided with a second annular groove, which is opposite to the first annular groove, and part of the sealing ring 6 can be accommodated in the second annular groove. This increases the sealing area between the second cover 2 and the material tray 4, that is, increases the sealing surface with the sealing ring 6 to three, which can improve the sealing effect and improve the user experience.

[0068] Specifically, the depth of the second annular groove is not set, as long as a portion of the sealing rings 6 can be placed within the second annular groove.

[0069] Preferably, along the radial direction of the sealing ring 6, the width of the sealing ring 6 may be slightly larger than, equal to, or smaller than the width of the second annular groove.

[0070] When the width of the sealing ring 6 is less than the width of the second annular groove, the height of the sealing ring 6 protruding from the first annular groove must be greater than or equal to the depth of the second annular groove. This ensures that the sealing ring 6 can seal the second cover 2 and the material tray 4.

[0071] When the width of the sealing ring 6 is greater than or equal to the width of the second annular groove, the height of the sealing ring 6 protruding from the first annular groove is less than or equal to the depth of the second annular groove. This ensures the stability of the connection between the second cover 2 and the material tray 4, while increasing the sealing area.

[0072] In this embodiment, the structure and number of the first snap-fit ​​structure are not limited, as long as the first snap-fit ​​structure and the second snap-fit ​​structure can cooperate.

[0073] In some possible embodiments, a first snap-fit ​​structure is provided on the inner peripheral wall of the first cover 1 along its circumference; a second snap-fit ​​structure is provided on the second cover 2 along its circumference to cooperate with the first snap-fit ​​structure; the first snap-fit ​​structure and the second snap-fit ​​structure cooperate, and the first cover 1 and the second cover 2 are relatively fixed along the axial direction of the first cover 1. By setting the mutually cooperating first snap-fit ​​structure and second snap-fit ​​structure, the stability of the connection between the first cover 1 and the second cover 2 can be ensured, and the relative rotation of the first cover 1 and the second cover 2 can be ensured. Moreover, the first snap-fit ​​structure and the second snap-fit ​​structure can only disengage when rotated to a preset angle, further ensuring the stability of the first cover 1 when rotating relative to the second cover 2.

[0074] In this embodiment, the first snap-fit ​​structure is a snap-fit ​​protrusion, and the second snap-fit ​​structure is a snap-fit ​​groove. The snap-fit ​​groove is provided with an installation port, and the snap-fit ​​protrusion can enter the snap-fit ​​groove through the installation port, thereby enabling the snap-fit ​​protrusion to rotate relative to the snap-fit ​​groove, thus enabling the first cover 1 to rotate relative to the second cover 2.

[0075] In some other possible embodiments, the inner peripheral wall of the first cover 1 is provided with at least two first snap-fit ​​structures at intervals, and the outer peripheral wall of the second cover 2 is provided with at least two second snap-fit ​​structures that cooperate with the at least two first snap-fit ​​structures.

[0076] Specifically, the first snap-fit ​​structure is a snap-fit ​​structure, and the second snap-fit ​​structure is a protruding structure that cooperates with the snap-fit ​​structure.

[0077] In some possible embodiments, the chassis assembly includes a chassis 5 and a tray 4 fixedly connected to the chassis 5; the chassis 5 has a first receiving cavity, and a portion of the tray 4 is disposed in the first receiving cavity; a rotatable connection position is disposed on the chassis 5. By making the chassis 5 and the tray 4 detachable, it is possible to quickly disassemble the tray 4, ensuring that the packaging box of the coating material can be quickly replaced when the tray 4 needs to be replaced, thereby increasing the speed of tray 4 replacement, increasing the reusability of the packaging box of the coating material, reducing the user's purchase cost, and improving the user's experience.

[0078] In this embodiment, the material tray 4 is used to hold the material. The material tray 4 is detachably connected to the base plate 5. The material tray 4 and the base plate 5 are provided with corresponding notches 51, and two mounting holes are provided on the base plate 5.

[0079] In this embodiment, the chassis 5 has a quadrilateral structure, and the structure of the tray 4 is not limited, as long as the tray 4 can be detachably connected to the chassis 5 and the tray 4 has a fourth snap-fit ​​structure that cooperates with the first cover 1.

[0080] Specifically, the material tray 4 has a circumferential structure protruding on the side away from the base plate 5, which cooperates with the second cover 2, and a fourth snap-fit ​​structure is provided on the outer periphery of the circumferential structure.

[0081] In this embodiment, the inner diameter of the sealing ring 6, which is disposed between the material tray 4 and the second cover 2, is larger than the inner diameter of the second receiving cavity, and the outer diameter of the sealing ring 6 is smaller than the outer diameter of the second receiving cavity. This can prevent the sealing ring 6 from protruding and affecting the aesthetics of the packaging box containing the coating material.

[0082] In some possible embodiments, at least two third snap-fit ​​structures 11 are provided on the inner peripheral wall of the first cover 1 along its circumference, and at least two fourth snap-fit ​​structures that cooperate with the at least two third snap-fit ​​structures 11 are provided on the outer peripheral wall of the material tray 4 along its circumference. The third snap-fit ​​structures 11 and the fourth snap-fit ​​structures cooperate with each other, and the first cover 1 and the material tray 4 are relatively fixed along the axial direction of the first cover 1. By setting the mutually cooperating third snap-fit ​​structures 11 and the fourth snap-fit ​​structures, the stability of the connection between the first cover 1 and the material tray 4 can be ensured. At the same time, it can be ensured that the first cover 1 and the material tray 4 can rotate relative to each other, and the third snap-fit ​​structures 11 and the fourth snap-fit ​​structures can only disengage when rotated to a preset angle, so as to prevent the packaging box of the coating material from being accidentally opened, thereby improving the user experience.

[0083] Specifically, the third snap-fit ​​structure 11 is a snap-fit ​​structure, and the fourth snap-fit ​​structure is a protruding structure that cooperates with the snap-fit ​​structure.

[0084] In some possible embodiments, at least two third snap-fit ​​structures 11 are equally spaced along the inner peripheral wall of the first cover 1. This arrangement ensures that the first cover 1 can disengage from the material tray 4 after rotating at a preset angle, thereby enabling the opening of the packaging box of the coating material.

[0085] In this embodiment, the number of third snap-fit ​​structures 11 is not limited and can be set according to the actual situation.

[0086] Preferably, there are four third snap-fit ​​structures 11, which are equally spaced on the inner sidewall of the first cover 1. There are also four fourth snap-fit ​​structures, which are equally spaced on the outer sidewall of the material tray 4.

[0087] In some possible embodiments, the rotation angle of the first cover 1 relative to the material tray 4 is 0°-45°. This ensures that the packaging box of the coating material can be opened by rotating the first cover 1 by a small angle, thereby shortening the opening time of the packaging box of the coating material and improving the user experience.

[0088] In this embodiment, the rotation angle of the first cover 1 relative to the material tray 4 is 0°-45°, 0°-15°, 0°-30°, 0°-45°, 15°-30°, 15°-45°, or 30°-45°, etc.

[0089] The process of opening the packaging box of the coating material: The user holds the first cover 1 and the base 5 with his / her hands respectively. The user's hands drive the first cover 1 to rotate relative to the base 5 by a preset angle until the third locking structure 11 on the first cover 1 disengages from the fourth locking structure on the material tray 4. After the user's hands drive the first cover 1 to disengage from the base 5, he / she continues to drive the first cover 1 and the second cover 2 to rotate relative to the base 5. At this time, the opening of the packaging box of the coating material is completed. Example

[0090] Referring to Figures 1 to 9, this embodiment provides a packaging box for a coating, including: a first cover 1; a second cover 2, the first cover 1 being rotatable relative to the second cover 2; a chassis assembly, the chassis assembly being engaged with the first cover 1, the first cover 1 being rotatable relative to the chassis assembly until the first cover 1 disengages from the chassis assembly; the chassis assembly having a rotatable connection position, the second cover 2 being pivotally connected to the chassis assembly through the rotatable connection position; the rotatable connection position being disposed on the side wall of the chassis assembly, and the two side walls adjacent to the side wall where the rotatable connection position is located being arranged parallel to each other; the first cover 1 being able to drive the second cover 2 to rotate relative to the chassis assembly until the first cover 1 opens relative to the chassis assembly.

[0091] In this embodiment, the cross-sectional shape of the packaging box of the coating is quadrilateral, which can be either rectangular or square.

[0092] In this embodiment, the first cover 1 is the outer cover of the packaging box of the coating material, so the cross-section of the first cover 1 is quadrilateral. The chassis assembly is fastened to the first cover 1, and the cross-section of the chassis assembly is also quadrilateral.

[0093] In this embodiment, the first cover 1 can rotate around the second cover 2. To ensure the smoothness of the rotation of the first cover 1 relative to the second cover 2, and to avoid excessive gaps between the first cover 1 and the second cover 2 during the rotation of the first cover 1 relative to the second cover 2, the inner wall of the first cover 1 is cylindrical, and the second cover 2 has a cylindrical structure.

[0095] In this embodiment, the first snap-fit ​​structure is a snap-fit ​​protrusion, and the second snap-fit ​​structure is a snap-fit ​​groove. The snap-fit ​​groove is provided with an installation port, and the snap-fit ​​protrusion can enter the snap-fit ​​groove through the installation port, thereby enabling the snap-fit ​​protrusion to rotate relative to the snap-fit ​​groove, thus enabling the first cover 1 to rotate relative to the second cover 2.

[0096] In this embodiment, one of the second cover 2 and the chassis assembly is provided with a pivot connection portion 21, and the other is provided with a notch 51 that mates with the pivot connection portion 21.

[0097] In this embodiment, a notch is provided on the chassis assembly, and a pivot connection part 21 is provided on the second cover 2. Specifically, when the chassis assembly includes a material tray 4 and a chassis 5, notches are provided at corresponding positions on the material tray 4 and the chassis 5.

[0098] In this embodiment, when a notch is provided on the chassis assembly and a pivot connection part 21 is provided on the second cover 2, the pivot connection part 21 protrudes from the side wall of the second cover 2 and a through hole is provided on the pivot connection part 21. The through hole contains a rotating shaft. After the rotating shaft is installed in the through hole, both ends of the rotating shaft protrude from both ends of the through hole. Mounting holes are provided at both opposite ends of the notch. Both ends of the rotating shaft extend into the mounting holes to realize the rotational connection between the second cover 2 and the chassis assembly.

[0099] Specifically, the length of the rotating shaft is slightly greater than the distance between the two mounting holes that are set opposite each other.

[0100] In this embodiment, the rotating connection is located in the middle region of the side wall of the chassis assembly.

[0101] In this embodiment, the structures on both sides of the rotating connection position on the chassis assembly are symmetrically arranged.
