[0035] Referring to Figures 1 to 9 , an embodiment of the present invention provides an environmentally friendly cosmetic packaging box, which includes a box body 100, a placement pad 200, and a box cover 300. The box body 100 has a receiving cavity 110 with an upward opening; the placement pad 200 is disposed in the receiving cavity 110, and a placement groove 210 for placing products is provided on the upper surface of the placement pad 200. A handle groove (not shown in the figure) that is located on the periphery of the placement groove 210 and communicates with the placement groove 210 is also formed on the upper surface of the placement pad 200; the box cover 300 has a closing cavity 310 with a downward opening, and a buffer structure is provided in the closing cavity 310. The buffer structure is arranged at intervals from the inner peripheral wall of the closing cavity 310. When the box cover 300 is closed on the box body 100, the inner peripheral wall of the closing cavity 310 fits against the outer peripheral wall of the box body 100, and the buffer structure is embedded downward into the receiving cavity 110 and presses against the placement pad 200; wherein, a first composite magnetic bamboo fiber layer (not shown in the figure) is provided on the bottom wall of the placement pad 200, and a second composite magnetic bamboo fiber layer (not shown in the figure) is provided on the bottom wall of the receiving cavity 110. A magnetic attraction force that attracts each other can be generated between the first composite magnetic bamboo fiber layer and the second composite magnetic bamboo fiber layer.

[0036] In the environmentally friendly cosmetic packaging box according to the embodiment of the present invention, when packaging, the product is placed in the accommodating cavity 110 on the placing pad 200. By providing a buffer structure in the covering cavity 310 of the box cover 300 that can be embedded in the accommodating cavity 110, the buffer structure can press downward on the placing pad 200 and the product, thereby being able to limit the position of the product and prevent the product from detaching from the placing groove 210 and colliding with the inner wall of the box cover 300 due to shaking or vibration during transportation, and further being able to protect the product and improve the safety of product transportation. Secondly, by providing a first composite magnetic bamboo fiber layer on the bottom wall of the placing pad 200 and a second composite magnetic bamboo fiber layer on the bottom wall of the accommodating cavity 110, the magnetic attraction force generated between the first composite magnetic bamboo fiber layer and the second composite magnetic bamboo fiber layer can fix the placing pad 200 and the box body 100, preventing the situation where the placing pad 200 detaches from the box body 100 together when the product is taken out from the placing groove 210. Thus, the product can be easily taken out from the placing groove 210, which is convenient for users to use, is beneficial to improving the practicality of the environmentally friendly cosmetic packaging box, and enhances the user experience. In addition, both the first composite magnetic bamboo fiber layer and the second composite magnetic bamboo fiber layer are environmentally friendly materials, which are convenient for recycling and reuse.

[0037] It can be understood that between the box cover 300 and the box body 100, a separable structure can be adopted, or the box cover 300 and the box body 100 can also be rotatably connected. The present invention does not make specific limitations on this.

[0038] In some embodiments, the first composite magnetic bamboo fiber layer is formed by mixing bamboo fibers and hard magnetic powder, and the content of the hard magnetic powder in the first composite magnetic bamboo fiber layer is 25wt%-30wt%; the second composite magnetic bamboo fiber layer is formed by mixing bamboo fibers and soft magnetic powder, and the content of the soft magnetic powder in the second composite magnetic bamboo fiber layer is 25wt%-30wt%.

[0039] In the above structure, by forming the first composite magnetic bamboo fiber layer by mixing bamboo fibers and hard magnetic powder, the bonding strength between the bamboo fibers and the hard magnetic powder can be improved, making the structure of the first composite magnetic bamboo fiber layer more stable. And by setting the content of the hard magnetic powder in the first composite magnetic bamboo fiber layer to 25wt%-30wt%, the first composite magnetic bamboo fiber layer can have good magnetism, which is beneficial to magnetic attraction and fixation with the second composite magnetic bamboo fiber layer. Similarly, by forming the second composite magnetic bamboo fiber layer by mixing bamboo fibers and soft magnetic powder, the bonding strength between the bamboo fibers and the soft magnetic powder can be improved, making the structure of the second composite magnetic bamboo fiber layer more stable. And by setting the content of the soft magnetic powder in the second composite magnetic bamboo fiber layer to 25wt%-30wt%, the second composite magnetic bamboo fiber layer can have good magnetism, which is beneficial to magnetic attraction and fixation with the first composite magnetic bamboo fiber layer.

[0040] In addition, by disposing hard magnetic powder in the first composite magnetic bamboo fiber layer, the first composite magnetic bamboo fiber layer forms a hard magnetic layer, which can effectively increase the coercivity and ensure a stable residual magnetism. By disposing soft magnetic powder in the second composite magnetic bamboo fiber layer, the second composite magnetic bamboo fiber layer forms a soft magnetic layer, which can effectively increase the magnetic permeability and form a low magnetic resistance path. The combination of hard magnetism and soft magnetism can effectively improve the magnetic flux and reduce the magnetic resistance, thereby increasing the adsorption force between the first composite magnetic bamboo fiber layer and the second magnetic bamboo fiber layer, making the fixation between the placement pad 200 and the box body 100 more stable.

[0041] It can be understood that the above-mentioned first composite magnetic bamboo fiber layer is formed by mixing bamboo fiber and hard magnetic powder. Specifically, in the first magnetic bamboo fiber layer of some embodiments, the bamboo fiber accounts for 55 wt%, the hard magnetic powder accounts for 30 wt%, and in addition, it also includes 10 wt% binder and 5 wt% water. The first composite magnetic bamboo fiber layer is formed by thermocompression curing after mixing the above four components.

[0042] It can be understood that the above-mentioned second composite magnetic bamboo fiber layer is formed by mixing bamboo fiber and soft magnetic powder. Specifically, in the second magnetic bamboo fiber layer of some embodiments, the bamboo fiber accounts for 60 wt%, the soft magnetic powder accounts for 25 wt%, and in addition, it also includes 10 wt% binder and 5 wt% water. The first composite magnetic bamboo fiber layer is formed by thermocompression curing after mixing the above four components.

[0043] It can be understood that the hard magnetic powder can specifically adopt NdFeB magnetic powder or other hard magnetic materials, and the soft magnetic powder can specifically adopt SrFe12O19 magnetic powder or other soft magnetic materials. The present invention does not make specific limitations in this regard.

[0044] In some embodiments, a first buffer layer (not shown in the figure) is disposed on the lower surface of the first composite magnetic bamboo fiber layer. The setting of the first buffer layer can protect and isolate the first composite magnetic bamboo fiber layer and the second composite magnetic bamboo fiber layer. Among them, the first buffer layer can specifically adopt a porous bamboo fiber layer, which can not only play a role in shock absorption and buffering, but also be green and environmentally friendly.

[0045] It can be understood that in order to protect and isolate the first composite magnetic bamboo fiber layer and the second composite magnetic bamboo fiber layer, in addition to disposing a first buffer layer on the lower surface of the first composite magnetic bamboo fiber layer, in some embodiments, a second buffer layer can also be disposed on the upper surface of the second composite magnetic bamboo fiber layer. Among them, the second buffer layer can specifically adopt a porous bamboo fiber layer, which can not only play a role in shock absorption and buffering, but also be green and environmentally friendly. It should be noted that in some embodiments, only the first buffer layer can be set, or only the second buffer layer can be set, or both the first buffer layer and the second buffer layer can be set at the same time. The present invention does not make specific limitations in this regard.

[0046] Reference Figure 2 and Figure 3 In some embodiments, the buffer structure includes a first elastic component, a second elastic component, and a pressing plate 340. The pressing plate 340 is disposed in the covering cavity 310 and is spaced apart from the inner peripheral wall of the covering cavity 310. The first elastic component includes a plurality of first elastic columns 320 disposed between the top wall of the covering cavity 310 and the pressing plate 340. The second elastic component includes a plurality of second elastic columns 330 located between the top wall of the covering cavity 310 and the pressing plate 340. The second elastic component is wound around the outer periphery of the first elastic component. When the box cover 300 is closed on the box body 100, in the up and down direction, the projections of all the first elastic columns 320 are located in the placement groove 210, the projections of all the second elastic columns 330 are located outside the placement groove 210, the diameter of the first elastic column 320 is smaller than that of the second elastic column 330, and the pressing plate 340 can be pressed against the upper surface of the placement pad 200 and deform under pressure.

[0047] By adopting the above structure, since the projection of the first elastic component is located in the placement groove 210, during the process of the box cover 300 being closed on the box body 100 from top to bottom, the first elastic column 320 can press against the product and deform, and the second elastic column 330 can press against the upper surface of the placement pad 200 and deform. Since the diameter of the first elastic column 320 is smaller than that of the second elastic column 330, the elasticity of the first elastic column 320 is smaller than that of the second elastic column 330. During the closing process of the box cover 300, the first elastic column 320 can be preferentially compressed and deformed to absorb the initial impact, and because of the smaller elasticity, it can protect the product and reduce the extrusion force exerted by the first elastic column 320 on the product. The second elastic column 330 can provide subsequent support due to its larger elasticity. Thus, under the combined action of the first elastic component and the second elastic component, the pressing plate 340 can better wrap the upper surface of the product and press against the upper surface of the placement pad 200, thereby effectively protecting the product and preventing the product from detaching from the placement groove 210 and colliding with the inner wall of the box cover 300 due to shaking or vibration during transportation, and further protecting the product and improving the safety of product transportation.

[0048] It can be understood that the pressing plate 340 can specifically adopt corrugated cardboard, honeycomb cardboard, or bamboo fiber board, and the present invention does not make specific limitations thereto.

[0049] It can be understood that the pressing plate 340 and the first elastic column 320, the second elastic column 330 can specifically adopt bonding. Specifically, the pressing plate 340 and the first elastic column 320, the second elastic column 330 can be bonded through starch-based glue, thereby improving the environmental protection of the cosmetic packaging box.

[0050] In some embodiments, both the first elastic column 320 and the second elastic column 330 are TPU elastic columns. TPU specifically refers to thermoplastic polyurethane material. The TPU elastic column has high strength and good elasticity, and can better cushion and buffer the product. In addition, the TPU elastic column is non-toxic and harmless, and has good recyclability, which is beneficial to improving the environmental protection performance of the cosmetic packaging box.

[0051] Referring to Figures 2 to 9 , in some embodiments, the outer sidewall of the placement pad 200 has a first locking portion 220, and the inner sidewall of the accommodation cavity 110 has a second locking portion 120 that can cooperate and lock with the first locking portion 220. When the placement pad 200 is inserted into the accommodation cavity 110 from top to bottom, the first locking portion 220 can lock with the second locking portion 120 and prevent the placement pad 200 from moving upward out of the accommodation cavity 110.

[0052] In the above structure, the settings of the first locking portion 220 and the second locking portion 120 can facilitate the installation of the placement pad 200 into the accommodation cavity 110 from top to bottom, and prevent the placement pad 200 from being taken out of the accommodation cavity 110 from bottom to top. Thereby, the placement pad 200 and the box body 100 can be further fixed, avoiding the situation that the placement pad 200 is separated from the box body 100 together when the product is taken out from the placement groove 210. Furthermore, the product can be easily taken out from the placement groove 210, which is convenient for users to use, beneficial to improving the practicality of the environmental protection cosmetic makeup box, and enhancing the user experience.

[0053] Referring to Figures 4 to 6 , in some embodiments, the second locking portion 120 is provided with a bent portion 130 with a protrusion facing the accommodation cavity 110. When the placement pad 200 is inserted into the accommodation cavity 110 from top to bottom, the first locking portion 220 presses against the bent portion 130 and pushes the bent portion 130 to expand downward. When the first locking portion 220 moves downward to the lower side of the bent portion 130, the bent portion 130 can prevent the first locking portion 220 from moving upward.

[0054] In the above structure, the bending portion 130 can be unfolded downward when pressed. Thus, when the placement pad 200 is placed into the accommodation cavity 110 from top to bottom, the side wall of the placement pad 200 can squeeze the bending portion 130 and drive the bending portion 130 to unfold downward. At this time, the bending portion 130 deforms in the direction close to the inner wall of the accommodation cavity 110, so that the placement pad 200 can be smoothly installed into the accommodation cavity 110. When the placement pad 200 is installed in place downward, the placement pad 200 is located below the bending portion 130. At this time, if the placement pad 200 is pulled upward, it will push the bending portion 130 to fold upward. At this time, the bending portion 130 bends in the direction away from the inner wall of the accommodation cavity 110 to form a convex structure with the relative convexity facing the inside of the accommodation cavity 110. Thus, it can prevent the placement pad 200 from moving upward, so as to limit the placement pad 200, avoid the situation that the placement pad 200 is separated from the box body 100 together when the product is taken out from the placement groove 210, and then enable the product to be easily taken out from the placement groove 210, which is convenient for users to use, is beneficial to improving the practicability of the environmental protection cosmetic makeup box, and enhances the user experience.

[0055] It can be understood that in the above structure, the first locking portion 220 can be specifically directly set as the outer surface of the placement pad 200.

[0056] Referring to Figures 4 to 6 , in some embodiments, the second locking portion 120 is formed by inverting and folding the upper edge of the box body 100 inward. The bending portion 130 has a guiding portion 131 and a blocking portion 132. The guiding portion 131 is formed by bending the lower edge of the second locking portion 120 upward along the direction close to the inside of the accommodation cavity 110. The blocking portion 132 is formed by bending the lower edge of the guiding portion 131 downward along the direction close to the inner wall of the accommodation cavity 110. The lower edge of the blocking portion 132 is also bent to form a fitting portion 133 that can fit with the inner wall of the accommodation cavity 110. When the placement pad 200 is installed in the accommodation cavity 110, the fitting portion 133 is clamped between the inner wall of the accommodation cavity 110 and the placement pad 200.

[0057] In the above structure, the second locking portion 120 is formed by folding the upper edge of the box body 100 inward, so that the second locking portion 120 and the box body 100 are integrally formed, and there is no need to add an additional connecting structure between the second locking portion 120 and the box body 100, which not only simplifies the structure of the cosmetic packaging box, but also makes the cosmetic packaging box more environmentally friendly. In addition, by setting the bending portion 130 as a guide portion 131 and a blocking portion 132 formed by bending the first locking portion 220 in sequence, the guide portion 131 is inclined from top to bottom toward the inside of the accommodating cavity 110, thereby guiding the downward placement of the placement pad 200, and the blocking portion 132 is inclined from top to bottom toward the direction away from the inside of the accommodating cavity 110, thereby blocking the upward movement of the placement pad 200. Therefore, in the process of embedding the placement pad 200 into the accommodating groove from top to bottom, the placement pad 200 can squeeze the guide portion 131 so that the guide portion 131 is deformed in a direction close to the inner wall of the accommodating cavity 110, and the guide portion 131 and the blocking portion 132 are expanded downward, thereby allowing the placement pad 200 to be smoothly installed downward into the accommodating cavity 110. In addition, since the lower edge of the blocking portion 132 is bent to form a fitting portion 133 that can fit with the inner wall of the accommodating chamber 110, the fitting portion 133 is sandwiched between the inner wall of the accommodating chamber 110 and the placement pad 200. When the placement pad 200 is taken out upward, friction is generated between the side wall of the placement pad 200 and the fitting portion 133, thereby generating resistance to the removal of the placement pad 200. When the placement pad 200 moves upward, it drives the fitting portion 133 to move upward, and the fitting portion 133 can push the blocking portion 132 to move upward. The blocking portion 132 and the guide portion 131 are moved so that the end connected to the blocking portion 132 moves closer to the interior of the accommodating cavity 110, that is, the bending portion is deformed to bulge toward the interior of the accommodating cavity 110, thereby blocking the upward movement of the placement pad 200, thereby preventing the placement pad 200 from being separated from the box body 100 when the product is taken out of the placement groove 210, so that the product can be easily taken out of the placement groove 210, which is convenient for users to use, is conducive to improving the practicality of the environmentally friendly cosmetic makeup box, and enhances the user experience.

[0058] It can be understood that in the above structure, the surface of the side of the fitting portion 133 close to the placement pad 200 can be set to be relatively rough, and the surface of the side of the fitting portion 133 away from the placement pad 200 can be set to be relatively smooth, that is, the roughness of the side of the fitting portion 133 close to the placement pad 200 is greater than the roughness of the side of the fitting portion 133 away from the placement pad 200, and when the placement pad 200 moves upward, the friction between the placement pad 200 and the fitting portion 133 is greater than the friction between the inner wall of the accommodating cavity 110 and the fitting portion 133, thereby enabling the placement pad 200 to drive the fitting portion 133 to move upward together when moving upward.

[0059] It can be understood that, in order to prevent the placement pad 200 from moving upward out of the receiving groove, in addition to clamping the fitting portion 133 between the inner wall of the receiving cavity 110 and the placement pad 200, in some embodiments, when the placement pad 200 is installed in the receiving cavity 110, the fitting portion 133 is located above the placement pad 200 and can abut against the upper surface of the placement pad 200. Thus, when the placement pad 200 is taken out upward, the upper surface of the placement pad 200 can abut against the lower end of the fitting portion 133 and push the fitting portion 133 to move upward. When the fitting portion 133 moves upward, it can push the blocking portion 132 to move upward and make the end where the blocking portion 132 is connected to the guiding portion 131 move closer to the inside of the receiving cavity 110, that is, cause the bending portion to deform with the convexity facing the inside of the receiving cavity 110. Thereby, the upward movement of the placement pad 200 can be blocked, and further, the situation that the placement pad 200 is separated from the box body 100 together when the product is taken out from the placement groove 210 can be avoided, so that the product can be easily taken out from the placement groove 210, which is convenient for users to use, is beneficial to improving the practicability of the environmentally friendly cosmetic makeup box, and enhances the user experience.

[0060] Referring to Figures 7 to 9 , in some embodiments, the first locking portion 220 includes a plurality of upper hook portions 221 disposed on the outer sidewall of the placement pad 200 and inclined outward from bottom to top. The upper hook portions 221 can swing along the direction close to the placement pad 200 under the action of external extrusion; the second locking portion 120 includes a plurality of lower hook portions disposed on the inner wall of the receiving cavity 110 and inclined along the direction close to the inside of the receiving cavity 110 from top to bottom. The lower hook portions can swing along the direction close to the inner wall of the receiving cavity 110 under the action of external extrusion; when the placement pad 200 is placed into the receiving cavity 110 from top to bottom, the upper hook portions 221 can be attached to the second locking portion 120 and move downward relative to the second locking portion 120, and the second locking portion 120 can prevent the upper hook portions 221 from moving upward.

[0061] In the above structure, by setting the first locking portion 220 as a plurality of upper hook portions 221 inclined outward from bottom to top and setting the second locking portion 120 as a plurality of lower hook portions inclined inward from top to bottom, the settings of the upper hook portions 221 and the lower hook portions can guide the placement pad 200 to be smoothly placed into the receiving cavity 110 of the box body 100 from top to bottom. When the placement pad 200 is moved out upward, a clamping connection will occur between the upper hook portions 221 and the lower hook portions to prevent the placement pad 200 from moving out upward. Thereby, the situation that the placement pad 200 is separated from the box body 100 together when the product is taken out from the placement groove 210 can be avoided, so that the product can be easily taken out from the placement groove 210, which is convenient for users to use, is beneficial to improving the practicability of the environmentally friendly cosmetic makeup box, and enhances the user experience.

[0062] It can be understood that the upper hook portion 221 can be integrally formed with the placement pad 200. Specifically, the upper hook portion 221 can be formed by shearing the outer side wall of the placement pad 200 from top to bottom. Thereby, the processing of the upper hook portion 221 can be facilitated, and an additional connection structure between the upper hook portion 221 and the placement pad 200 can be avoided, which is beneficial to improving the environmental protection of the cosmetic packaging box. Similarly, the lower hook portion can also be integrally formed with the box body 100. Specifically, the lower hook portion can be formed by shearing the inner wall of the box body 100 from bottom to top. Thereby, the processing of the lower hook portion can be facilitated, and an additional connection structure between the lower hook portion and the box body 100 can be avoided, which is beneficial to improving the environmental protection of the cosmetic packaging box.

[0063] It can be understood that when the first locking portion 220 and the second locking portion 120 adopt the combination of the upper hook portion 221 and the lower hook portion, the upper hook portion 221 and the lower hook portion can be arranged in one-to-one correspondence. And in the horizontal direction, the distance between two adjacent upper hook portions 221 is greater than the width of the lower hook portion, and the distance between two adjacent lower hook portions is greater than the width of the upper hook portion 221. Thus, when the product is taken out from the placement groove 210, the placement pad 200 moves upward following the product and makes the upper hook portion 221 and the corresponding lower hook portion engage with each other, so as to prevent the placement pad 200 from moving upward away from the accommodating groove following the product, enabling the product to be easily taken out from the placement groove 210. When the user needs to take out the placement pad 200 from the accommodating cavity 110, the placement pad 200 can be pushed horizontally, causing relative movement between the upper hook portion 221 and the lower hook portion and making the upper hook portion 221 and the lower hook portion stagger from each other. At this time, the placement pad 200 can be easily taken out, thereby enabling the user to easily take out the placement pad 200 for the box body 100 to be used alone or for the box body 100 and the placement pad 200 to be compressed and recycled.

[0064] It can be understood that in addition to setting the second locking portion 120 as the lower hook portion, in some embodiments, the second locking portion 120 can also be set as a flocked portion provided on the inner wall of the accommodating cavity 110. Thus, when the placement pad 200 is moved upward, the upper hook portion 221 will be stuck into the flocked portion, thereby being able to prevent the placement pad 200 from moving upward. In this structure, the flocked portion is specifically formed by flocking the inner wall of the accommodating cavity 110. Specifically, the flocked portion can be adhered to the inner wall of the accommodating cavity 110 by an adhesive. Among them, the flocked layer can specifically adopt recycled cotton fibers, which is both environmentally friendly and can better prevent the upper hook portion 221 from moving upward.

[0065] In some embodiments, an elastic layer (not shown in the figure) and a water-absorbing layer (not shown in the figure) are sequentially arranged on the inner wall of the placement groove 210. The water-absorbing layer can be attached to the surface of the product and push the elastic layer to be compressed and deformed under pressure.

[0066] In the above structure, the setting of the water-absorbing layer can prevent the product from leaking or spilling and contaminating the placement pad 200, and keep the accommodating cavity 110 dry. The setting of the elastic layer can elastically squeeze and clamp the product, improve the clamping force of the placement groove 210 on the product, so that the product can be placed more firmly in the placement groove 210, thereby being able to limit the position of the product and prevent the product from detaching from the placement groove 210 and colliding with the inner wall of the box cover 300 due to shaking or vibration during transportation, and further being able to protect the product and improve the safety of product transportation.

[0067] It can be understood that the water-absorbing layer may specifically include a hydrophobic bamboo fiber non-woven fabric layer, an alginate calcium composite gel layer, and a PLA layer arranged in sequence from top to bottom. The hydrophobic bamboo fiber non-woven fabric layer can direct the flow of liquid and prevent the liquid from remaining on the surface of the placement groove 210. The alginate calcium composite gel layer can quickly absorb and lock water. The PLA layer can be used as an anti-backflow bottom layer to isolate and protect the underlying elastic layer and the placement pad 200. In addition, the water-absorbing layer can also directly adopt a bamboo fiber layer, and the present invention does not make specific limitations thereto.

[0068] It can be understood that the elastic layer may specifically adopt a bamboo fiber layer, a honeycomb cardboard, a degradable rubber layer, etc., and the present invention does not make specific limitations thereto.

[0069] The embodiments of the present invention have been described in detail above with reference to the drawings, but the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
