[0030] like Figures 1-7 As shown in the figure, this application discloses a cosmetic packaging box inner liner structure 100, which can also be referred to as a replacement core. The cosmetic packaging box inner liner structure 100 includes a box base 12 and a sealing element 13.

[0031] The box base 12 has a side wall 121. A first protruding edge 122 and a second protruding edge 123 are provided in the side wall 121. The first protruding edge 122 and the second protruding edge 123 are both arranged parallel to the side wall 121. The second protruding edge 123 is disposed between the first protruding edge 122 and the side wall 121. A receiving groove 124 is formed between the first protruding edge 122 and the second protruding edge 123. A first part 132 of the sealing member 13 is disposed in the receiving groove 124. A connecting block 131 is provided on the first part 132. The connecting block 131 is used to connect the sealing member 13 and the box base 12.

[0032] In this embodiment, the side surface of the seal 13 facing away from the box seat 12 is used for welding aluminum foil, and the surface of the aluminum foil is used for assembling mesh fabric.

[0033] In this embodiment of the application, during the manufacturing process, specifically when assembling the mesh fabric, the connecting block 131 melts under the action of ultrasound, achieving adhesion between the sealing element 13 and the box base 12. That is, the sealing element 13 can be adhered to the receiving groove 124 through the connecting block 131, thereby ensuring that when the mesh fabric is fixed on the sealing element 13, it can be fixedly placed on the box base 12. When the user uses the cosmetic packaging box inner liner structure 100, the mesh fabric will not fall off during the user's pressing action. Thus, by utilizing ultrasonic bonding technology, the assembly process of the sealing element 13 and the box base 12 is simplified, production efficiency is improved, and production costs are reduced.

[0034] Therefore, by providing a receiving groove 124 formed by the first protruding edge 122 and the second protruding edge 123 in the side wall 121 of the box base 12, and placing the first part 132 of the sealing member 13 therein, the sealing member 13 and the box base 12 are bonded together by the connecting block 131, ensuring the stability of the sealing member 13 fixed in the box base 12, improving the sealing performance of the packaging box. Moreover, this design can also firmly set the mesh on the box base 12. When the user presses the mesh during use, the mesh will not fall off due to external force, thus ensuring the user experience and product hygiene.

[0035] In this embodiment, the seal 13 is composed of two different materials: polyethylene terephthalate (PET) and thermoplastic elastomer (TPE). PET is a thermoplastic polyester with good mechanical properties, heat resistance, and chemical resistance. It is transparent, tough, and not easily broken, thus providing structural strength and shape stability in the seal 13. TPE is a thermoplastic plastic with rubber elasticity, combining the processing properties of plastics and the elasticity of rubber. TPE is soft, easy to mold, and has good sealing performance and impact resistance. Therefore, in the seal 13, it not only provides a sealing effect but also increases the fit with the housing 12.

[0036] As a preferred embodiment, the two-color seal 13 in this application is an integrally molded structure, manufactured by co-injection molding or two-color injection molding process to ensure that the two materials are tightly bonded.

[0037] like Figure 4 As shown, the sealing element 13 has a ring-shaped structure, and there are multiple connecting blocks 131. The multiple connecting blocks 131 are arranged sequentially at intervals and surround the first part 132.

[0038] Multiple connecting blocks 131 are arranged around the first part 132 of the seal 13, providing multiple fixing points and reducing the burden on individual connecting blocks 131. These fixing points are evenly distributed, allowing the seal 13 to be more evenly and firmly fixed in the receiving groove 124 of the housing 12, and also making the processing of the seal 13 simpler and more convenient. Secondly, because the connecting blocks 131 are arranged around the seal 13, the contact area between the seal 13 and the housing 12 is increased, which not only improves the sealing performance of the inner liner structure, but also increases the connection strength between the seal 13 and the housing 12, making the inner liner structure more stable. This allows the mesh to withstand greater external forces without being easily damaged.

[0039] In a preferred embodiment, the connecting block 131 is disposed at the bottom end of the sealing member 13 and extends toward the bottom surface of the receiving groove 124 so as to be able to contact the bottom surface of the receiving groove 124.

[0040] By adopting the above-described structure, the connecting block 131 can have a larger contact area with the bottom surface of the receiving groove 124 during the bonding process, thereby enhancing the bonding strength and stability. Furthermore, the contact between the connecting block 131 and the bottom surface of the receiving groove 124 can effectively prevent the seal 13 from moving in the vertical direction, i.e., limit the direction of the side wall 121, and also restrict the tilting or rotation of the seal 13, ensuring the correct position of the seal 13 in the housing 12 and ensuring that the seal 13 remains fixed during long-term use.

[0041] like Figures 5-6 As shown, the connecting block 131 has a toothed structure. During the ultrasonic bonding process, due to its special shape, the toothed connecting block 131 can be more tightly bonded to the box base 12, thereby improving the stability and durability of the bonding.

[0042] In a preferred embodiment, the connecting block 131 is disposed on the two side surfaces of the sealing member 13 facing the first protrusion 122 and the second protrusion 123, and the connecting block 131 can contact the first protrusion 122 and the second protrusion 123 respectively.

[0043] Understandably, the connecting block 131 is disposed on every inch of the surface of the first part 132 of the seal 13 so as to be in contact with the bottom surface of the first protrusion 122, the second protrusion 123 and the receiving groove 124.

[0044] By connecting the connecting block 131 to the first protruding edge 122, the second protruding edge 123, and the bottom surface of the receiving groove 124, the sealing element 13 is fixed in three directions, greatly improving the stability and firmness of the sealing element 13. Furthermore, the fixing of the connecting block 131 in three directions enhances the deformation resistance of the entire inner liner structure, enabling it to better withstand external forces, such as the compression of the mesh fabric during user use.

[0045] like Figure 7 As shown, a mounting groove 125 is provided between the side wall 121 and the second protrusion 123. The receiving groove 124 is used to receive the first part 132, and the mounting groove 125 is used to receive the second part 133 of the seal 13, so that the seal 13 can be supported on the second protrusion 123.

[0046] Along the direction of the sidewall 121, the cross-sectional shape of the seal 13 is U-shaped.

[0047] In this embodiment of the application, the inner liner structure also includes a cover 11, which is used to cover the box seat 12. Specifically, the cover 11 and the box seat 12 have two modes: one is that the cover 11 closes the box seat 12, and the other is that the cover 11 opens the box seat 12.

[0048] In this embodiment of the application, the first protruding edge 122 and the bottom surface of the box seat 12 form a receiving cavity 126, which is used to store materials. The first protruding edge 122 and the second protruding edge 123 form a receiving groove 124, and the second protruding edge 123 and the side wall 121 form a placement groove 125. The two parts of the sealing member 13 are respectively disposed in the receiving groove 124 and the placement groove 125.

[0049] Therefore, based on the above structural form, by respectively setting the two parts of the sealing element 13 in the receiving groove 124 and the placement groove 125, the sealing element 13 can be tightly fitted between the box seat 12 and the cover 11. This ensures a tight seal between the cover 11 and the box seat 12 when the inner liner structure is in the closed state, preventing air, moisture, and other contaminants from entering and protecting the quality and hygiene of the inner liner structure. Furthermore, the first protruding edge 122 and the second protruding edge 123 enhance the structural strength of the box seat 12, and the U-shaped design of the sealing element 13 enhances the reliability of its placement on the box seat 12. This ensures that the sealing element 13 guarantees both the sealing performance and the durability of the inner liner structure.

[0050] In a preferred embodiment, the connecting block 131 is disposed at the bottom end of the first portion 132 and / or the bottom end of the second portion 133.

[0051] In this embodiment, the inner liner structure further includes a sealing ring 14. Both the sealing ring 14 and the second portion 133 of the sealing element 13 are disposed in the mounting groove 125, and the sealing element 13 can be fitted onto the first protruding edge 122 via the sealing ring 14. Therefore, in this embodiment, the connecting block 131 is only disposed at the bottom end of the first portion 132, which simplifies the design of the sealing element 13, reduces the complexity of the manufacturing process, and lowers production costs. Furthermore, the connecting block 131 being concentrated at the bottom end of the first portion 132 provides sufficient fixing force to maintain the position of the sealing element 13 in the receiving groove 124, while avoiding the complexity that might arise from disposing of the connecting block 131 in the second portion 133.

[0052] In this embodiment of the application, a filler 15 is provided between the interlayer of the U-shaped seal 13 and the second protrusion 123 to reduce the gap between the seal 13 and the second protrusion 123.

[0053] In the embodiments of this application, the filler is a soft rubber material.

[0054] In this embodiment, the filler and the second protrusion 123 are in an interference fit, specifically an upper and lower abutment interference fit.

[0055] Therefore, the design of the U-shaped seal 13 better adapts to the shape of the second convex edge 123, and the interference fit of the filler 15 effectively reduces gaps, thereby improving sealing performance. Furthermore, the design of the filler 15 ensures the stable position of the seal 13 within the housing 12, preventing displacement even during transportation or use. In addition, the soft rubber filler 15 absorbs and disperses external forces, reducing wear between the seal 13 and the second convex edge 123 and extending the service life of the inner liner structure.

[0056] In this embodiment of the application, the cover 11 is provided with a third protruding edge 111 on the side facing the box seat 12. The third protruding edge 111 is arranged parallel to the side wall 121. The third protruding edge 111 can be embedded between the sealing ring 14 and the side wall 121 to seal the gap between the cover 11 and the box seat 12.

[0057] By setting a third protruding edge 111 on the cap 11 and interacting with the sealing ring 14, a double sealing effect is achieved between the cap 11 and the sealing element 13 on the inner liner structure, which better enhances the sealing performance of the packaging and ensures the hygiene of the materials.

[0058] like Figure 2 As shown, along the setting direction of the sidewall 121, the first part 132 and the second part 133 are of equal length, and the bottom end of the first part 132 is spaced apart from the bottom surface of the receiving groove 124.

[0059] In this embodiment of the application, a gap of 3-5 mm is provided between the bottom end of the first part 132 and the bottom surface of the receiving groove 124.

[0060] By designing the first part 132 and the second part 133 to have equal lengths, visual and structural symmetry is provided, improving the balance of the seal 13 fitted onto the housing 12.

[0061] Meanwhile, along the setting direction perpendicular to the sidewall 121, the radial dimension of the first portion 132 is smaller than the radial dimension of the second portion 133.

[0062] Since the radial dimension of the first part 132 is smaller than that of the second part 133, when the seal 13 is installed in the receiving groove 124, the first part 132 will be subjected to a certain compressive force due to its smaller radial dimension, which makes the seal 13 fit more tightly on the first protrusion 122, thereby improving the sealing performance. Furthermore, the connecting block 131 is set on the first part 132 with a smaller radial dimension, which can concentrate the fixing force in the smaller area of ​​the receiving groove 124, making the position of the seal 13 in the receiving groove 124 more stable, reducing the installation difficulty caused by the size difference, and also making the contact between the connecting block 131 and the first protrusion 122 and the second protrusion 123 tighter, which can effectively prevent the seal 13 from falling off when subjected to external force.

[0063] The foregoing description has fully disclosed the specific embodiments of this application. It should be noted that any modifications made by those skilled in the art to the specific embodiments of this application do not depart from the scope of the claims. Accordingly, the scope of the claims of this application is not limited to the foregoing specific embodiments.
