Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., 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 this application described herein can be implemented in orders other than those illustrated or described herein.

[0038] like Figures 1-14 As shown in the figure, this application discloses a cosmetic packaging box inner liner 100, which can also be referred to as a replacement core. The cosmetic packaging box inner liner 100 includes a box cover 11 and a box base 12. The box base 12 is used to hold materials, which refer to a viscous solid-liquid mixture such as foundation liquid or cream.

[0039] The lid 11 is used to cover the box base 12. The lid 11 has a flange 111 on the side facing the box base 12. The box base 12 has a side wall 121. The flange 111 and the side wall 121 are parallel.

[0040] The flange 111 is provided with a first connector 112 on the side facing the side wall 121, and the side wall 121 is provided with a second connector 124 at the position corresponding to the first connector 112. The first connector 112 and the second connector 124 are adapted to be used for connecting the box cover 11 and the box base 12.

[0041] In this embodiment, the first connector 112 is a protrusion structure and the second connector 124 is a groove structure. The protrusion structure and the groove structure are adapted to each other, that is, the protrusion structure can be embedded in the groove structure to realize the connection between the box cover 11 and the box base 12. For example, the protrusion structure can be a hemisphere with a diameter of 2 mm, and the size of the groove structure is slightly larger than the protrusion structure so that the protrusion structure can be embedded in the groove structure.

[0042] In other embodiments, the first connector 112 is also a groove structure, and the second connector 124 is a protrusion structure. The specific structural forms of the first connector 112 and the second connector 124 are not limited, as long as they meet the connection requirements of the lid 11 and the base 12.

[0043] In this embodiment, the flange 111 extends toward the side of the housing 12 so as to extend into the interior of the housing 12; preferably, it fits against the sidewall 121.

[0044] In this embodiment of the application, the gate of the box cover 11 is located on the side of the box cover 11 facing the box base 12, and is located at the center of the box cover 11.

[0045] In this embodiment, both the cap and the box seat 12 are made of polyethylene terephthalate (PET). PET is a thermoplastic polyester with good mechanical properties, heat resistance and chemical resistance. It is transparent, tough and not easy to break, so it can provide structural strength and shape stability in the sealing ring 131.

[0046] Therefore, based on the above structural form, through the matching design of the first connector 112 and the second connector 124, the lid 11 and the base 12 can be easily connected and separated, while also ensuring a tight fit between the lid 11 and the base 12, reducing the gap between them, thereby improving the sealing performance of the packaging box and protecting the materials from contamination or leakage. Secondly, the design of the flange 111 enhances the overall stability of the packaging box, making it more robust and less prone to deformation during use.

[0047] like Figures 5-6 As shown, the box cover 11 has a storage groove 114 on the side opposite to the box base 12, and the box cover 11 has a storage wall 113 to form the storage groove 114. The storage groove 114 is used to store the coating.

[0048] The storage wall 113 and the flange 111 are arranged in parallel, and the storage wall 113 and the side wall 121 are arranged in a collinear manner.

[0049] In this embodiment of the application, the storage slot 114 is used to store application tools, which include cosmetic auxiliary tools such as powder puffs, sponges, and brushes.

[0050] Understandably, the storage slot 114 is located on the outside of the lid 11. When the lid 11 is closed, the powder puff will not come into direct contact with the material inside the base 12, reducing the possibility of powder puff contamination.

[0051] Therefore, by setting the storage wall 113 and the side wall 121 of the box base 12 in a collinear manner, the edge of the storage wall 113 is aligned with the edge of the side wall 121, thus maintaining the consistency of the appearance and the integrity of the structure of the inner liner of the packaging box 100.

[0052] In this embodiment of the application, a hand fastener 117 is provided on the edge of the outer periphery of the storage slot 114 for the user to open and close the box cover 11.

[0053] Preferably, a hinge protrusion 118 is provided on the opposite side of the hand buckle 117, and a hinge seat 125 is provided on the box base 12 at the position corresponding to the hinge protrusion 118. The hinge protrusion 118 and the hinge seat 125 are adapted to accommodate cylindrical objects such as pins, thereby realizing the rotatable connection between the box cover 11 and the box base 12. The assembly method includes at least the following two: First, the pin can penetrate the hinge protrusion 118 and the hinge seat 125, in which case one pin is sufficient; Second, the pin does not penetrate the hinge protrusion 118 and the hinge seat 125, in which case two pins are required to be set opposite each other.

[0054] like Figures 8-10 The inner liner further includes a sealing assembly 13, which is disposed on the side of the box base 12 facing the box cover 11, and the upper surface of the sealing assembly 13 is used to mount a mesh fabric.

[0055] The lid 11 is also provided with a protrusion 115 on the side facing the base 12. The protrusion 115 contacts the sealing component 13 to press the mesh fabric, ensuring that the mesh fabric is fixed and preventing the inner liner of the cosmetic box from falling off during use.

[0056] Therefore, by pressing the mesh with the protrusion 115, the sealing assembly 13 can more effectively seal the space inside the box seat 12 and prevent external pollutants from entering.

[0057] like Figure 5 As shown, the protrusion 115 is disposed close to the flange 111, and the side of the protrusion 115 facing the flange 111 is inclined, so that a recess 116 is formed between the protrusion 115 and the flange 111.

[0058] It is understood that the protrusion 115 is located close to the flange 111, and there is a certain distance between the protrusion 115 and the flange 111. The side of the protrusion 115 facing the flange 111 is an inclined surface, and the inclined surface and the flange 111 form an angle, forming the recess 116.

[0059] Preferably, the angle between the inclined surface and the horizontal plane can be between 30° and 60°, so that the protrusion 115 can provide appropriate compressive force to the sealing component 13, making the contact between the sealing component 13 and the mesh fabric tighter, and ensuring the sealing performance of the protrusion 115 and the sealing component 13 for the cosmetic packaging box. Furthermore, the inclined surface design allows the protrusion 115 to better disperse force when subjected to pressure, reducing local stress concentration and improving the structural stability of the entire lid 11.

[0060] In a preferred embodiment, the outer wall surface of the flange 111 is in contact with the inner wall surface of the side wall 121, and the flange 111 is at least partially embedded between the sealing assembly 13 and the side wall 121.

[0061] Preferably, at least half the length of the flange 111 is embedded between the sealing assembly 13 and the sidewall 121.

[0062] Preferably, the flange 111 is embedded to a depth between the sealing assembly 13 and the sidewall 121 in the range of 0.5-3 mm. This depth not only ensures that the flange 111 provides sufficient sealing pressure to the sealing assembly 13, but also does not excessively compress the sealing assembly 13.

[0063] Therefore, by embedding the flange 111 between the sealing assembly 13 and the side wall 121, the pressure on the sealing surface of the sealing assembly 13 can be increased, thereby improving the sealing effect and preventing material from being contaminated by external factors. Furthermore, the embedded design of the flange 111 also helps to fix the position of the sealing assembly 13, reducing displacement of the sealing assembly 13 due to vibration during use and improving the overall structural stability. In addition, the embedded design of the flange 111 also makes the assembly of the lid 11 and the base 12 simpler and faster, because the flange 111 can act as a guide, helping the user to accurately align and close the lid 11.

[0064] In a preferred embodiment, the flange 111 is interference-fitted with the sealing assembly 13.

[0065] Specifically, in this embodiment, the sealing assembly 13 includes a sealing ring 131 and a sealing ring 132. The housing 12 includes a first flange 122 and a second flange 123 arranged parallel to the side wall 121. The sealing ring 131 is sleeved on the second flange 123, such that both ends of the sealing ring 131 are embedded in the receiving groove formed by the side wall 121 and the second flange 123, and the receiving groove formed by the second flange 123 and the first flange 122. The sealing ring 132 is disposed in the receiving groove formed by the side wall 121 and the second flange 123. The sealing ring 132 can limit and fix the sealing ring 131 to the second flange 123, thereby fixing the sealing ring 131 to the housing 12. Thus, the flange 111 and the sealing ring 132 are interference-fitted.

[0066] Therefore, the interference fit design ensures that there is no gap between the flange 111 and the sealing ring 132, thus providing efficient sealing performance. Furthermore, the interference fit, which fixes the sealing ring 132 between the flange 111 and the sealing ring 131, also maintains the position of the sealing ring 131, preventing it from shifting during use. In addition, the interference fit design simplifies the assembly process of the cover 11 and the base 12, as the fit between the sealing ring 132 and the flange 111 is itself a precise alignment and fixing mechanism.

[0067] like Figure 9 As shown, along the setting direction of the side wall 121, the cross-sectional shape of the sealing ring 131 is U-shaped, and the interlayer of the sealing ring 131 can be fitted onto the second protruding edge 123;

[0068] A filler is provided between the interlayer of the sealing ring 131 and the second protrusion 123 to reduce the gap between the sealing ring 131 and the second protrusion 123.

[0069] In this embodiment, the filler is made of soft rubber.

[0070] In this embodiment, the filler and the second protrusion 123 are in an interference fit, specifically an upper and lower abutment interference fit.

[0071] Therefore, based on the above structural form, the design of the U-shaped sealing ring 131 can better adapt to the shape of the second convex edge 123. Combined with the interference fit of the filler, this effectively reduces gaps, thereby improving sealing performance. Furthermore, the design of the filler ensures the stable position of the sealing ring 131 within the box seat 12, preventing displacement even during transportation or use. In addition, the soft rubber filler can absorb and disperse external forces, reducing wear between the sealing ring 131 and the second convex edge 123, and extending the service life of the cosmetic packaging box liner 100.

[0072] In this embodiment of the application, the sealing ring 131 is provided with a plurality of protrusions, including a first protrusion 1311 and a second protrusion 1312. The protrusions are all disposed on the side of the sealing ring 131 away from the second protrusion 123, and the plurality of protrusions are arranged sequentially at intervals along the extension direction of the first protrusion 122.

[0073] The sealing ring 132 has a groove on the side facing the sealing ring 131. The groove is adapted to at least one of the convex rings to limit the sealing ring 131 and ensure the stability and accuracy of the seal.

[0074] In a preferred embodiment, the plurality of convex rings are arranged in parallel. The parallel arrangement of the convex rings can evenly distribute the pressure and reduce deformation or damage caused by excessive pressure on a single convex ring.

[0075] As a preferred embodiment, the depth and width of the groove are slightly larger than the diameter of the convex ring so that the convex ring can smoothly enter the groove and achieve positioning.

[0076] In this embodiment, the grooves of the first convex ring 1311 and the sealing ring 132 are matched so that the sealing ring 132 fixes the sealing ring 131 on the inner side wall; the second convex ring is disposed at the bottom end of the sealing ring 132 so that the sealing ring 131 is fixed on the box seat by itself.

[0077] Therefore, the double fixing effect of the two convex rings makes the sealing ring 131 more firmly fixed in the housing 12, improving the stability and reliability of the seal; the second convex ring abuts against the sealing ring 132, preventing the sealing ring 131 from falling off due to external force during use, and ensuring long-term sealing effect.

[0078] As a preferred embodiment, the inner diameter of the sealing ring 132 is smaller than the inner diameter of the sealing ring 131. The purpose of this arrangement is that when the sealing ring 132 is fitted onto the sealing ring 131, it can always provide a compressive force towards the sealing ring 131, that is, always fix the sealing ring 131 on the housing 12 to form an airtight effect.

[0079] In a preferred embodiment, the sealing ring 131 has a plurality of protrusions 1313 at its bottom end facing the first convex edge 122. The plurality of protrusions 1313 are arranged sequentially at intervals along the circumferential direction of the sealing ring 131 to provide shock absorption when the mesh fabric is assembled on the upper surface of the sealing ring 131.

[0080] In a preferred embodiment, the bottom end of the sealing ring 132 is provided with a guide slope 1321, which is used to guide the assembly of the sealing ring 132, providing guidance for the assembly of the sealing ring 132 and improving assembly efficiency.

[0081] like Figure 11 As shown, the end of the sealing ring 132 facing the flange 111 has a protruding structure 1322, which is used to contact the flange 111 to form a sealing point;

[0082] Along the extending direction of the flange 111, a relief groove 1323 is provided below the protruding structure 1322. The relief groove 1323 is used to accommodate the protruding structure 1322 that is deformed by the flange 111. That is, the relief groove 1323 can accommodate the deformation of the protruding structure 1322 when it is squeezed by the flange 111, so as to avoid damage to the protruding structure 1322 due to excessive compression and extend the service life of the sealing ring 132.

[0083] like Figure 11 As shown, a sealing rib 1324 is provided on the side of the sealing ring 132 facing the side wall. The sealing rib 1324 is used to press against the side wall 121 to achieve the limiting and fixing of the sealing ring 132.

[0084] In a preferred embodiment, the flange 111 is arranged around and continuously on the cover 11.

[0085] In other embodiments, the flange 111 may also be a strip-shaped protrusion 115 structure, evenly distributed on the lid 11; the flange 111 may also be completely continuous without interruption, or it may be segmented continuous, that is, composed of multiple continuous small segments forming a complete ring.

[0086] Therefore, the surrounding and continuous flanges 111 can not only evenly distribute the pressure on the contact surface between the lid 11 and the base 12, but also enhance the structural strength of the lid 11 itself.

[0087] In a preferred embodiment, there are multiple first connectors 112, which are arranged sequentially at intervals.

[0088] In this embodiment of the application, the box base 12 is a square with an arc-shaped structure, and there are three first connectors 112. The three first connectors 112 are respectively disposed on the three sides of the box cover 11, except for the side where the box cover 11 and the box base 12 are connected.

[0089] In other embodiments, there may be two, four or more first connectors 112, depending on the size of the lid 11 and the required connection stability. The spacing between the first connectors 112 may be equidistant, for example, 2 cm apart, or unequal, depending on the design and functional requirements of the lid 11.

[0090] Therefore, the multiple spaced first connectors 112 can provide stronger connection stability, ensuring a more secure connection between the lid 11 and the base 12. Also, since the connectors are distributed in multiple locations, it is easier for the user to open or close the lid 11, reducing the difficulty caused by single-point force.

[0091] This application also discloses a cosmetic packaging box, which includes an outer shell and the aforementioned cosmetic packaging box liner 100. The cosmetic packaging box liner 100 is disposed in the outer shell. After the material in the cosmetic packaging box liner 100 is used up, a new cosmetic packaging box liner 100 filled with material can be replaced for reuse by the user.

[0092] As a preferred implementation method, such as Figure 12 As shown, a slot 126 is provided at the bottom of the outer periphery of the box base 12. There are multiple slots 126, which are arranged in sequence at intervals, preferably three, and are respectively provided on the three sides of the box base 12 excluding the hinge seat 125, so as to realize the replacement function of the cosmetic packaging box liner 100, so as to be compatible with the corresponding structure provided on the inner bottom of the outer shell.

[0093] As a preferred implementation method, such as Figure 12 As shown, notches 127 are provided at the four top corners of the box base 12. The notches 127 are used to abut against the inner bottom of the outer shell to achieve a stable fit between the box base 12 and the inner bottom, avoiding the introduction of a third component, so as to achieve stable fixation between the box base 12 and the inner bottom.

[0094] 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.
