[0035] Example:

[0036] The coating material packaging box is a component specially designed for use inside 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.

[0037] like Figure 1-5As shown, the embodiment of the present application provides a coating material packaging box, a support ring 120 and a loading tray 130. The loading tray 130 is sleeved in the support ring 120, and a first sealing ring 150 is provided between the loading tray 130 and the support ring 120. The first sealing ring 150 is arranged to be attached to the outer side surface of the loading tray 130 and / or the inner side surface of the support ring 120. The loading tray 130 and the support ring 120 are interference-fitted by the first sealing ring 150, so that the first sealing ring 150 can seal the loading tray 130. The loading tray 130 is used to store the coating material.

[0038] Furthermore, the support ring 120 and the loading tray 130 are made of plastic material, and the first sealing ring 150 is made of elastic material, and the hardness of the plastic material is greater than the hardness of the elastic material.

[0039] Specifically, the sealing cover 110, the support ring 120 and the loading tray 130 can be made of hard plastics with high hardness, high toughness and high strength, such as polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC); preferably, they can be made of polyethylene terephthalate (PET). PET material has excellent strength and rigidity, good transparency and high temperature resistance, which can ensure the high strength, high hardness and high transparency of the packaging box, thereby improving the overall quality and grade of the product. The first sealing ring 150 can be made of TPE thermoplastic elastomer material. TPE material is a thermoplastic elastomer material with excellent elasticity. Its hardness is significantly lower than that of PET material. It has the elasticity of rubber at room temperature and can be plasticized at high temperature. It has the advantages of high elasticity, aging resistance and oil resistance. It can well fill the small gap caused by the difference in material hardness, thereby ensuring the sealing of the packaging box.

[0040] This application combines PET and TPE, two materials with different properties, so that the packaging box not only has high strength, high hardness and high transparency, ensuring the durability of the product, but also greatly improves the sealing performance of the product, which is conducive to improving the safety of the storage of the coated material.

[0041] In the embodiment of the present application, a first sealing ring is arranged between the support ring and the loading tray for sealing. The first sealing ring can be deformed when squeezed, thereby filling any small gap between the two to achieve a sealing effect, avoiding contamination of the coating material body by contact with external air during storage, preventing air from entering the loading tray through the gap between the support ring and the loading tray, and further improving the sealing of the packaging box.

[0042] Furthermore, the support ring 120 and the first sealing ring 150 are integrally formed by two-color injection molding; and / or, the loading tray 130 and the first sealing ring 150 are integrally formed by two-color injection molding. The two-color injection molding process ensures that the structural connection between the support ring, the loading tray and the first sealing ring is very tight, and can ensure a seamless connection between the first sealing ring and the support ring or the loading tray, without additional seams or adhesives, which greatly enhances the strength, stability and sealing of the entire structure. The integral molding of the first sealing ring 150 and the support ring 120 or the loading tray 130 can also reduce production time, reduce production costs, and improve product production efficiency and aesthetics.

[0043] Further, a step mounting portion 121 is provided inside the support ring 120, and the loading tray 130 is provided below the step mounting portion 121. In a possible embodiment, the first sealing ring 150 is provided below the step mounting portion 121, and the inner side wall of the first sealing ring 150 is tightly fitted with the support ring 120; preferably, the first sealing ring 150 is attached along the inner side wall of the support ring 120 to form an annular sealing structure, and the outer side wall of the first sealing ring 150 is aligned with the inner side wall of the support ring 120 on the same annular plane or protrudes from the inner side wall of the support ring 120. In another possible embodiment, the first sealing ring 150 is provided at the upper edge of the loading tray 130, and the inner side wall of the first sealing ring 150 is tightly fitted with the loading tray 130; preferably, the outer side wall of the first sealing ring 150 is aligned with the outer side wall of the loading tray 130 on the same annular plane. Specifically, the first sealing ring 150 is attached along the upper edge of the loading tray 130 to form an annular sealing structure. In another possible embodiment, the inner side wall of the support ring 120 and the outer side wall of the material loading tray 130 are both provided with a circle of first sealing ring 150, and the two first sealing rings 150 are staggered in the axial direction of the support ring 120, and two sealing structures are provided between the support ring 120 and the material loading tray 130, which further improves the tightness of the connection between the support ring 120 and the material loading tray 130. When the material loading tray 130 is connected to the support ring 120, the first sealing ring 150 will be squeezed and deformed due to the elastic properties of its material. This deformation ensures a tight sealing connection between the material loading tray 130 and the support ring 120, effectively preventing the leakage of the coating material such as liquid or powder, thereby ensuring the safety and sealing of the product.

[0044] Furthermore, an annular protrusion 160 matching with the first sealing ring 150 is provided on the inner side wall of the support ring 120 or the outer side wall of the loading tray 130 . When the loading tray 130 is connected to the support ring 120 , the first sealing ring 150 is squeezed and deformed by the annular protrusion 160 .

[0045] Specifically, in one possible embodiment, an annular protrusion 160 is provided on the inner side wall of the support ring 120. When the material loading tray 130 is sealed and connected to the support ring 120, the annular protrusion 160 cooperates with the first sealing ring 150. The first sealing ring 150 is provided at the upper edge of the material loading tray 130. The inner side wall of the first sealing ring 150 is tightly fitted with the material loading tray 130. The first sealing ring 150 is squeezed and deformed by the annular protrusion 160. In another possible embodiment, an annular protrusion 160 cooperating with the first sealing ring 150 is provided on the outer side wall of the material loading tray 130. The first sealing ring 150 is provided on the inner side wall of the support ring 120. The inner side wall of the first sealing ring 150 is tightly fitted with the support ring 120; preferably, the outer side wall of the first sealing ring 150 and the inner side wall of the support ring 120 are aligned on the same annular plane.

[0046] In the embodiment of the present application, during the assembly process of the material loading tray 130 and the support ring 120, the annular protrusion 160 contacts the first sealing ring 150 and exerts an extrusion effect on it. Since the first sealing ring 150 is elastic, it will deform under the extrusion of the annular protrusion 160, thereby filling any small gap between the two and achieving a sealing effect. Through the cooperation of the annular protrusion 160 and the first sealing ring 150, the sealing between the material loading tray 130 and the support ring 120 can be significantly enhanced to prevent the coating material from leaking or external impurities from entering.

[0047] Further, the annular protrusion 160 is disposed below the step mounting portion 121, and the thickness of the annular protrusion 160 is L, and the thickness of the annular protrusion 160 is less than the thickness of the first sealing ring 150, so that during the sealing process, the first sealing ring 150 can be more effectively compressed and deformed, thereby filling the small gap between the loading tray 130 and the support ring 120, and improving the sealing performance. In this embodiment, the thickness of the annular protrusion 160 and the first sealing ring 150 are both dimensions along the axial direction of the support ring.

[0048] Furthermore, a mesh 170 is sandwiched between the step mounting portion 121 and the upper edge of the loading tray 130. The mesh 170 is fixedly connected to the lower surface of the step mounting portion by bonding, hot pressing, etc. By using the mesh 170, the coating material can be evenly distributed on the mesh, which is convenient for users to take evenly and avoids the accumulation and waste of the coating material. In another embodiment, the mesh 170 may not be installed, but a sponge for absorbing and containing the material may be used in the loading tray 130, and the sponge completely covers the bottom of the loading tray and leaves enough space for the coating material to absorb. The packaging box design of this embodiment is compatible with two different ways of using a mesh and a sponge. Through different ways of use, the packaging box can be suitable for different types of coating materials, such as powder, paste, etc., which broadens the scope of use of the packaging box and improves the applicability and flexibility of the packaging box.

[0049] Furthermore, an annular embedding groove 122 is provided below the inner side wall of the support ring 120 , and an annular embedding strip 131 matching with the annular embedding groove 122 is provided on the outer side wall of the loading tray 130 .

[0050] Furthermore, at least one engaging structure 123 is provided below the annular groove 122, and an engaging groove 132 matching the engaging structure 123 is provided between the annular strip 131 and the base of the material loading tray 130. Preferably, the arc length of the engaging structure 123 is not less than 10 mm to ensure the connection strength between the material loading tray and the support ring. In this embodiment, three engaging structures 123 are evenly arranged along the circumference on the inner side surface of the annular groove 122, and the arc length of each engaging structure 123 is not less than 30 mm.

[0051] In the embodiment of the present application, during the assembly of the material loading tray 130 and the support ring 120, the annular fillet 131 is aligned with the annular groove 122, and the annular fillet 131 of the material loading tray 130 is pressed into the annular groove 122, while ensuring that the snap-fit ​​groove 132 corresponds to the snap-fit ​​structure 123. Appropriate pressure is applied to completely embed the annular fillet 131 into the annular groove 122, while ensuring that the snap-fit ​​groove 132 and the snap-fit ​​structure 123 are tightly matched, thereby fixing the position of the material loading tray 130. Through the cooperation of the annular groove 122 and the annular fillet 131, and the tight cooperation of the snap-fit ​​structure 123 and the snap-fit ​​groove 132, a stable connection between the material loading tray 130 and the support ring 120 is achieved, which can effectively prevent the material loading tray 130 from loosening or falling off during use.

[0052] Furthermore, the distance from the first sealing ring 150 to the annular fillet 131 is H1, and the range of H1 is 4mm-8mm. Preferably, in some embodiments, H1 can be 4mm, 5mm, 6mm, 7mm or 8mm. Specifically, appropriately limiting the distance H1 from the first sealing ring 150 to the annular fillet 131 can significantly reduce the process difficulty during the injection molding process of the first sealing ring 150, thereby improving production efficiency and reducing production costs; it can avoid the problem of reduced hardness of the support ring 120 and / or the loading tray 130 due to too close distance to ensure the hardness of the packaging box and extend its service life, while ensuring the sealing performance between the first sealing ring 150 and the annular fillet 131, effectively preventing leakage of the coating body, and improving the sealing and safety of the equipment.

[0053] Further, the thickness from the step mounting portion 121 to the bottom surface of the support ring 120 is H2, and the range of H2 is 10mm-18mm; the thickness of the first sealing ring 150 is H3, and the range of H3 is 3mm-8mm. Optionally, the thickness H3 of the first sealing ring 150 can be 5mm-7mm; preferably, H3 can be 5mm, 6mm or 7mm. The ratio of H2 to H3 is in the range of 0.25-0.65.

[0054] Specifically, the loading tray 130 is sealed and arranged below the step mounting portion 121 through the first sealing ring 150. The step mounting portion 121 is fixedly mounted in the support ring 120; or, the step mounting portion 121 and the support ring 120 are integrally formed. Optionally, the thickness H2 from the step mounting portion 121 to the bottom surface of the support ring 120 ranges from 12mm to 16mm; preferably, H2 can be 12mm, 13mm, 14mm, 15mm or 16mm. The ratio of H2 to H3 can be 0.3-0.5; preferably, the ratio of H2 to H3 can be 0.35, 0.4, 0.45 or 0.5. In a possible embodiment, the thickness H2 from the step mounting portion 121 to the bottom surface of the support ring 120 is 14mm, the thickness H3 of the first sealing ring 150 is 6mm, and the ratio of H2 to H3 is 0.5.

[0055] In the present application, the first sealing ring 150 is arranged between the outer side surface of the loading tray 130 and the inner side surface of the support ring 120, and the ratio of the thickness H2 from the step mounting portion 121 to the bottom surface of the support ring 120 to the thickness H3 of the first sealing ring 150 is controlled within the range of 0.25-0.65. By optimizing the ratio relationship between the structure and thickness of the support ring and the sealing ring in the packaging box assembly, the contact height between the second sealing ring and the support ring is ensured to be within a reasonable range. While maintaining the overall structural strength of the product, the volume of the loading tray can be increased, and the connection sealing between the loading tray and the support ring can be improved.

[0056] Further, the thickness of the loading tray 130 is H4, the range of H4 is 12mm-22mm, and the ratio of the thickness H3 of the first sealing ring 150 to H4 is 0.2-0.7.

Optionally, the ratio of H3 to H4 ranges from 0.3-0.6; preferably, the ratio of H3 to H4 can be 0.3, 0.4, 0.5 or 0.6. In a possible implementation, the thickness H4 of the loading tray 130 is 15mm, the thickness H3 of the first sealing ring 150 is 6mm, and the ratio of H3 to H4 is 0.4.

[0057] In the embodiment of the present application, the inner depth of the material loading tray 130 is in the range of 10mm-20mm, the inner diameter of the material loading tray 130 is in the range of 40mm-60mm, and the volume of the material loading tray 130 is in the range of 12mL-30mL. It can adapt to various specifications of coating materials, and it is neither too large to waste space or materials, nor too small to limit the capacity. The material loading tray can load enough coating materials while avoiding unnecessary waste of space.

[0058] The present application controls the ratio of the thickness H4 of the loading tray 130 to the thickness H3 of the first sealing ring 150 within the range of 0.2-0.7. By optimizing the structure and size relationship between the loading tray 130 and the first sealing ring 150, it is ensured that when the loading tray 130 is connected to the support ring 120, the thickness of the first sealing ring 150 is within a reasonable range. While maintaining the overall structural strength of the product, the volume of the loading tray can be increased, thereby improving the sealing of the connection between the loading tray and the support ring.

[0059] Further, the coating material packaging box includes a sealing cover 110, which is disposed on the upper opening of the support ring 120, and the sealing cover 110 and the support ring 120 are sealed and connected via a second sealing ring 140. The sealing cover 110 and the support ring 120 are interference-fitted via the second sealing ring 140, so that the second sealing ring 140 can seal the support ring 120.

[0060] like Figure 4 and Figure 5 As shown, the sealing cover 110 is rotatably connected to the support ring 120 through the hinge assembly 400. The support ring 120 is fixedly provided with a first ring body 124 and a second ring body 125, the second ring body 125 is located outside the first ring body 124, the second sealing ring 140 is located between the first ring body 124 and the sealing cover 110, and the sealing cover 110 and the second ring body 125 are engaged and fixed. The hinge assembly 400 includes a first hinge 410, a second hinge 420 and a hinge shaft, the first hinge 410 is fixedly mounted on the sealing cover 110, and the second hinge 420 is fixedly mounted on the support ring 120. During assembly, after the first hinge 410 and the second hinge 420 are butt-jointed, the hinge shaft is passed through the first hinge 410 and the second hinge 420 to rotatably connect the sealing cover 110 with the support ring 120. The sealing cover 110 and the supporting ring 120 are fixed by means of a clamping point and a clamping groove, a clamping point and a clamping point, a clamping hook and a clamping point, etc.

[0061] Optionally, a second sealing ring 140 is fixedly disposed on at least one of the outer wall of the sealing cover 110 and the inner wall of the support ring 120. In a first possible implementation, a circle of the second sealing ring 140 is disposed on the inner wall of the support ring 120, and the second sealing ring 140 is airtightly attached to the outer wall of the sealing cover 110. In a second possible implementation, a circle of the second sealing ring 140 is disposed on the outer wall of the sealing cover 110, and the second sealing ring 140 is airtightly attached to the inner wall of the support ring 120. Figure 1As shown, the second sealing ring 140 is located at the lower end surface of the sealing cover 110. Optionally, the second sealing ring 140 is an annular structure with both upper and lower ends open. A circle of the second sealing ring 140 is provided on the lower end surface of the sealing cover 110, and the surface of the sealing cover 110 in contact with the second sealing ring 140 is an arc surface, thereby improving the sealing performance between the sealing cover 110 and the support ring 120. In a third possible implementation, the inner side wall of the support ring 120 and the outer side wall of the sealing cover 110 are both provided with a circle of the second sealing ring 140, and the two second sealing rings 140 are airtightly fitted. The above three methods can all achieve the purpose of sealing the loading tray 130.

[0062] Optionally, the second sealing ring 140 is integrally formed with the sealing cover 110 and / or the support ring 120 by two-color injection molding. The support ring 120 and the second sealing ring 140 or the sealing cover 110 and the second sealing ring 140 are integrally formed by two-color injection molding, so that the bonding strength between the second sealing ring 140 and the support ring 120 or the second sealing ring 140 and the sealing cover 110 is high and the sealing effect is good.

[0063] In the embodiment of the present application, the sealing cover and the support ring of the coating material body packaging box are sealed by a second sealing ring, and the support ring and the loading tray are sealed by a first sealing ring.
