Description

Technical Field

[0001] This utility model relates to the field of cosmetic containers technology, and in particular to a twist-type cosmetic container. Background Technology

[0002] In the cosmetics packaging industry, replaceable containers are increasingly favored due to their environmental friendliness and economy. These containers typically consist of a reusable outer shell and a replaceable inner liner to hold cosmetics. Once the cosmetics in the inner liner are completely used up, the user can remove the inner liner from the outer shell and replace it with a new one, thus completing the product update.

[0003] Currently, most replaceable containers on the market use a snap-fit ​​structure for assembly and disassembly of the inner liner and outer shell. During the repeated assembly and disassembly of the outer shell and inner liner, the snap-fit ​​area is subjected to continuous friction and stress, leading to wear, deformation, or even breakage. Consequently, the outer shell may not be able to securely hold the new inner liner, and the outer shell may become unusable prematurely.

[0004] Therefore, there is an urgent need to provide a cosmetic container that can slow down the wear rate of the parts where the outer shell is combined with the inner liner, thereby extending the service life of the outer shell. Summary of the Invention

[0005] This utility model aims to at least solve one of the technical problems existing in the prior art. One object of this application is to provide a twist-type cosmetic container. According to the twist-type cosmetic container of this application, the wear rate of the part of the outer shell used for assembly with the inner liner can be slowed down, thereby extending the service life of the outer shell.

[0006] A torsion cosmetic container according to the present invention includes: a main body having an axis, the main body having an inner peripheral wall along the axis, the inner peripheral wall and a portion of the main body defining a cavity, and the inner peripheral wall having a one-way channel in a radial direction away from the axis.

[0007] The inner liner, at least a portion of which can be accommodated in the cavity, has a sliding portion extending radially along the axis on its outer peripheral wall;

[0008] The one-way channel is provided with at least one stop in the circumferential direction along the axis, and the sliding part is configured to be able to slide unidirectionally through the one-way channel due to the constraint of the stop.

[0009] In this application, after the inner liner is inserted into the cavity of the main body, its sliding part simultaneously enters the one-way channel. Since the one-way channel is equipped with a stop portion that has a one-way limiting function, when the inner liner is twisted in a preset direction, causing the sliding part to pass the stop portion, it will be limited by the stop portion and unable to twist in the opposite direction. It can only continue to rotate in the original twisting direction until it detaches from the main body. This utility model achieves the combination and disassembly of the main body and the inner liner through one-way twisting. Compared with existing snap-fit ​​structures, it can slow down the wear rate of the parts of the main body used for combining with the inner liner, thereby extending the service life of the main body.

[0010] In some embodiments, the main body has a bottom wall, and part of the main body is the bottom wall.

[0011] In some embodiments, the unidirectional channel is configured as a U-shaped groove structure.

[0012] In some embodiments, the sliding portion is configured as a convex structure.

[0013] In some embodiments, the inclined surface gradually slopes along the sliding portion in the direction of passage of the one-way channel.

[0014] In some embodiments, the unidirectional channel has a first opening and a second opening, the first opening and the second opening being respectively disposed on both sides of the stop portion and extending through to the top of the inner peripheral wall along the extension direction of the axis.

[0015] In some embodiments, a plurality of stop portions are provided, and the plurality of stop portions are arranged at intervals along the unidirectional channel.

[0016] In some embodiments, the twist-type cosmetic container includes an entry state, a blocking state, and a disengagement state;

[0017] In the entry state, the sliding part slides from the first opening into the one-way channel and is located on one side of the stop part;

[0018] In the stopped state, the sliding part slides through the one-way channel and slides in one direction due to the stopping effect of the stopping part;

[0019] In the disengaged state, the sliding part passes through the one-way channel and disengages from the one-way channel through the second opening.

[0020] In some embodiments, the main body is provided with a plurality of one-way channels at intervals, and the inner liner is provided with a plurality of stops at intervals, wherein the one-way channels correspond one-to-one with the stops.

[0021] In some embodiments, the body component includes:

[0022] The base has a cavity, and the stop portion is formed in the cavity;

[0023] The inner fitting is fixed to the chamber;

[0024] The inner sleeve has a channel portion with a hole that penetrates the inner sleeve. The stop portion is located at the hole and cooperates with the channel portion to form the one-way channel.

[0025] In some embodiments, the base is formed with a protrusion, the stop extends along the extension direction of the axis on one side of the protrusion, the inner sleeve is provided with a slot, and a guide groove is formed on one side of the slot, the protrusion and the slot are fitted together, and the stop passes through the guide groove.

[0026] In some embodiments, the base is formed with a buckle, and the inner sleeve is formed with a buckle claw, the buckle engaging with the buckle claw such that the base and the inner sleeve are combined together.

[0027] In some embodiments, the main body further includes an outer cover that can be fitted onto the base.

[0028] In some embodiments, a groove for embedding a lens is formed on the inner side of the outer cover.

[0029] In some embodiments, the inner liner includes:

[0030] Inner seat, the sliding portion is formed in the inner seat;

[0031] The inner cover is able to fit onto the inner seat.

[0032] In this application, when the inner component is assembled into the cavity of the base, the protrusion of the base is simultaneously inserted into the slot of the inner component. When the protrusion is stopped by the end of the slot, the inner component is assembled with the base. At this time, a portion of the stop portion formed on one side of the protrusion protrudes into the channel portion of the inner component and is located at a preset hole position. This structure allows the stop portion to form a one-way channel with the channel portion without the need for external force to deform, which helps to reduce the processing difficulty of the one-way channel. At the same time, the double sliding fit system between the protrusion and the slot, and between the stop portion and the guide groove, can provide an auxiliary guiding effect for the assembly process of the base and the inner component.

[0053] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0054] In related technologies, the cosmetic packaging industry commonly adopts a design scheme where the outer shell and inner liner can be separated. Among them, the snap-fit ​​structure is the current mainstream assembly method. Users can press to make the protrusion of the inner liner snap into the buckle, thus combining the outer shell and the inner liner. Applying greater pulling force to the inner liner can separate the inner liner from the outer shell. However, during the cycle of combining and disassembling the outer shell and the inner liner, the snap-fit ​​parts are subjected to continuous friction and stress, leading to wear, deformation, and even breakage. This makes it impossible to firmly fix the new inner liner, thus reducing its service life.

[0055] Please see Figures 1-2 and Figure 4 In this embodiment of the application, a twist-type cosmetic container includes a main body 10 and an inner liner 20. The main body 10 has an axis P1 and an inner peripheral wall is constructed along the axis P1. The inner peripheral wall and a portion of the main body 10 together define a cavity. A one-way channel 101 is formed in the radial direction away from the axis P1 of the inner peripheral wall. At least a portion of the inner liner 20 can be accommodated in the cavity. A sliding portion 201 extends from the outer peripheral wall of the inner liner 20 in the radial direction of the axis P1. The one-way channel 101 is provided with at least one stop portion 102 in the circumferential direction of the axis P1. The sliding portion 201 is configured to be limited by the stop portion 102 and can slide unidirectionally through the one-way channel 101.

[0056] The main body 10 is a component for providing assembly support for the inner liner 20. It has an integrally formed annular inner peripheral wall along the axis P1. The inner peripheral wall has a one-way channel 101 in a radial direction away from the axis P1. The one-way channel 101 is a channel that allows the component to pass through in one direction in a preset direction. The one-way channel 101 has a stop 102 as a guide structure to restrict the reverse movement of the component. The inner peripheral wall and part of the main body 10 together form a cylindrical cavity that can be used to accommodate the inner liner 20. The outer peripheral wall of the inner liner 20 has a sliding part 201 integrally formed at the position of the one-way channel 101. The sliding part 201 can be a mating structure for cooperating with the one-way channel 101 and restricting the torsional direction of the inner liner 20. When the inner liner 20 is inserted into the cavity along the extension direction of axis P1, the sliding part 201 can enter the one-way channel 101. After the user applies a circumferential torsional force to the inner liner 20, the sliding part 201 will travel along the preset trajectory of the one-way channel 101 and cooperate with the stop part 102 when it passes through it, so that the inner liner 20 is installed in the cavity. If the user continues to twist the inner liner 20, the sliding part 201 can continue to travel along the preset trajectory of the one-way channel 101, so that the inner liner 20 can be removed from the cavity. If the user twists the inner liner 20 in the opposite direction, the stop part 102 will interfere with the sliding part 201, thereby restricting the reverse rotation of the inner liner 20.

[0057] After the inner liner 20 is inserted into the cavity of the main body 10, its sliding part 201 simultaneously enters the one-way channel 101. Since the one-way channel 101 is provided with a stop part 102 with a one-way limiting function, when the inner liner 20 is twisted in a preset direction, causing the sliding part 201 to pass the stop part 102, it will be limited by the stop part 102 and cannot twist in the opposite direction. It can only continue to rotate in the original twisting direction until it detaches from the main body 10. This design can realize the assembly and disassembly of the inner liner 20 through one-way twisting, thereby effectively slowing down the wear rate of the stop part 102, extending the service life of the main body 10, and allowing the main body 10 to replace the inner liner 20 more times.

[0058] For example, the main body 10 and the inner liner 20 can both be containers such as boxes, cans or bottles.

[0059] For example, the one-way channel 101 has a sidewall, and the sliding part 201 can conform to the sidewall of the one-way channel 101 and travel along a preset trajectory.

[0060] For example, the preset trajectory can be a preset path or trajectory line for the movement of the component.

[0061] For example, depending on the depth of the cavity and the height of the inner liner, the inner liner 20 can be partially or completely contained within the cavity.

[0062] In some embodiments, please refer to Figures 2-3 The main body 10 is provided with a bottom wall, and part of the main body 10 is the bottom wall.

[0063] The main body 10 has an annular inner peripheral wall, which together with the bottom wall forms a cylindrical cavity. When the inner liner 20 is inserted into the cavity along the extension direction of axis P1, the bottom wall can shield the bottom end face of the inner liner 20, thereby reducing wear on the end face during use or assembly.

[0064] For example, the upper surface of the bottom wall can form a surface contact fit with the bottom end face of the inner liner 20, thereby providing bottom support for the inner liner 20 and further improving the stability of the inner liner 20 after installation.

[0065] In some embodiments, please refer to Figure 2 and Figure 4 The combination of these elements results in the unidirectional channel 101 being constructed as a U-shaped groove structure.

[0066] The inner circumferential wall has a one-way channel 101 in the radial direction away from the axis P1. When the inner liner 20 is installed in the cavity, the sliding part 201 can cooperate with the one-way channel 101 as the inner liner 20 twists. The one-way channel 101 adopts a U-shaped groove structure design, which allows the sliding part 201 to enter and exit the one-way channel 101 from both ends. At the same time, it can also constrain the movement trajectory of the sliding part 201, thereby limiting the maximum torsional stroke of the inner liner 20.

[0067] In some embodiments, please refer to Figure 2 The sliding part 201 is constructed as a convex structure.

[0068] The sliding part 201 on the outer peripheral wall of the inner liner 20 adopts a convex structure design. The outline size of the convex is adapted to the width of the one-way channel 101. When the inner liner 20 is installed in the cavity, the convex can enter the one-way channel 101. After the user applies a circumferential torsional force to the inner liner 20, the convex will travel along the preset trajectory of the one-way channel 101 and can pass normally through the stop part 102. When attempting to circumferentially twist the inner liner 20 in the opposite direction, the stop part 102 will interfere with the convex, limiting the reverse displacement of the convex by resisting it, thereby effectively constraining the reverse torsional movement of the inner liner 20.

[0069] In some embodiments, please refer to Figures 1-2 , Figure 4 and Figure 7 The stop portion 102 is constructed as a convex structure, and the stop portion 102 has an inclined surface M1, which gradually slopes along the sliding portion 201 in the passing direction of the one-way channel 101.

[0070] The stop part 102 adopts a convex structure design with an inclined surface M1. The inclined surface M1 gradually tilts along the sliding part 201 in the direction of passage of the one-way channel 101, specifically gradually tilting towards the axis P1. When the user applies a circumferential torsional force to the inner liner 20, the sliding part 201 on the outer peripheral wall of the inner liner 20 will move along the preset trajectory of the one-way channel 101. When the sliding part 201 moves to the position of the stop part 102, it will be in close contact with the inclined surface M1. Under the continuous action of the torsional force, the sliding part 201 slides along the inclined surface M1 until it completely passes the stop part 102 and continues to move along the preset trajectory. When attempting to drive the inner liner 20 to rotate circumferentially in the opposite direction, the sliding part 201 will come into contact with the non-inclined side of the stop part 102. The stop part 102 prevents the reverse displacement of the sliding part 201 by interference, thereby effectively limiting the reverse torsional movement of the inner liner 20.

[0071] For example, please refer to Figure 7 The non-sloping side of the stop portion 102 has a first stop surface M2, which is connected to one end of the slope M1 and is used to form an abutment with the sliding portion 201, thereby preventing the reverse displacement of the sliding portion 201.

[0072] In some embodiments, please refer to Figures 1-2 and Figure 4 The combination of the two, the one-way channel 101 has a first opening 103 and a second opening 104, the first opening 103 and the second opening 104 are respectively disposed on both sides of the stop part 102, and extend to the top of the inner peripheral wall along the extension direction of the axis P1.

[0073] The one-way channel 101, designed with a U-shaped groove structure, has a first opening 103 and a second opening 104. The two openings extend upward along the extension direction of axis P1 and penetrate to the top of the inner peripheral wall. The stop part 102 is located between the first opening 103 and the second opening 104. When the inner liner 20 is combined or separated from the main body 10, the sliding part 201 of its outer peripheral wall can enter or leave the one-way channel 101 through the first opening 103 and the second opening 104 respectively. This opening design can avoid interference between the sliding part 201 and the top edge of the inner peripheral wall, and improve the smoothness of the assembly process of the inner liner 20.

[0074] For example, the first opening 103 and the second opening 104 are the two ends of the one-way channel 101 of the U-shaped groove structure, and the two have the same structural dimensions. They extend upward along the extension direction of the axis P1 and penetrate to the top end face of the inner peripheral wall, thereby forming an open structure so that the sliding part 201 of the inner liner 20 can enter or leave the one-way channel 101.

[0075] In some embodiments, please refer to Figures 1-2 and Figure 4The combination of the two types of components allows the twist-type cosmetic container to have an entry state, a blocking state, and a disengagement state. In the entry state, the sliding part 201 slides into the one-way channel 101 from the first opening 103 and is located on one side of the blocking part 102. In the blocking state, the sliding part 201 slides through the blocking part 102 and is restricted by the blocking effect of the blocking part 102. In the disengagement state, the sliding part 201 passes through the one-way channel 101 and disengages from the one-way channel 101 through the second opening 104.

[0076] When the inner liner 20 is assembled into the cavity of the main body 10 along the extension of axis P1, the sliding part 201 enters the one-way channel 101 through the first opening 103. When the user applies a circumferential torsional force in a preset direction to the inner liner 20, the sliding part 201 will move along the preset trajectory of the one-way channel 101. When the sliding part 201 moves to the position of the stop part 102, the stop part 102 achieves a limiting constraint on the reverse rotation of the inner liner 20 through interference, making it difficult for it to twist back. At this time, the inner liner 20 is limited and installed in the cavity. If the torsional force is continued to be applied in the original direction, the sliding part 201 can continue to move along the preset trajectory until it reaches the second opening 104 at the other end of the one-way channel 101. At this time, the sliding part 201 can disengage from the one-way channel 101 through the second opening 104, thereby releasing the constraint of the main body 10 on the inner liner 20, so that the inner liner 20 can be smoothly removed from the cavity.

[0077] In some embodiments, please refer to Figures 1-2 , Figure 4 and Figure 7 The combination of multiple stops 102 is provided, and the multiple stops 102 are arranged at intervals along the one-way channel 101.

[0078] The sliding part 201 travels along the preset trajectory of the one-way channel and will come into close contact with the inclined surface M1 when it passes the stop part 102. After the sliding part 201 passes the stop part 102, the two are no longer in contact, and the circumferential torsional resistance of the inner tube 20 is significantly reduced, making the operation more convenient and smooth. By arranging multiple stop parts 102 at intervals in the one-way channel 101, the torsional stroke of the inner tube 20 can form a staged limit and damping feedback, realizing an alternating cycle of close contact constraint and easy rotation, giving the operation process a clear sense of hierarchy. At the same time, the sliding part 201 will hit the side wall of the one-way channel 101 the moment it passes each stop part 102, forming a regular "click" sound feedback. This tactile and auditory collaborative design effectively enhances the user's interactive fun while ensuring the accuracy of the torsional operation.

[0079] For example, please refer to Figure 4 and Figure 7The combination of the two stops 102, namely the first stop 102A and the second stop 102B, is arranged at intervals in the one-way channel 101. The two stops are arranged sequentially along the preset trajectory of the one-way channel 101. When the sliding part 201 moves circumferentially along the preset trajectory, it will cooperate with the first stop 102A and the second stop 102B in sequence to realize the staged limit and damping feedback function.

[0080] For example, please refer to Figures 1-2 , Figure 4 , Figure 7 and Figure 10 In addition to the first stop surface M2, the second stop portion 102B also has a second stop surface M3. The second stop surface M3 is connected to the other end of the inclined surface M1, and the sliding portion 201 is formed with a rounded corner R1. When the sliding portion 201 passes the first stop portion 102A along the preset trajectory, if the user stops applying the circumferential torsional force, the first stop surface M2 of the first stop portion 102A and the second stop surface M3 of the second stop portion 102B will form a bidirectional constraint, further enhancing the limiting effect on the sliding portion 201, so that the inner liner 20 is limited and installed in the cavity. Only when the user continues to apply the circumferential torsional force in the preset direction can the rounded corner R1 of the sliding portion 201 pass the second stop surface M3, and then pass the second stop portion 102B, so as to disengage from the one-way channel 101 from the second opening 104, so that the inner liner 20 can be taken out. It should be noted that the distance between the second stop surface M3 and the side wall of the one-way channel 101 is smaller than the distance between the first stop surface M2 and the side wall of the one-way channel 101. The parameters of the second stop surface M3 and the fillet R1 can be configured according to actual usage requirements, as long as they can be matched. No specific limitations are made here.

[0081] In some embodiments, please refer to Figures 2-3 The main body 10 is provided with multiple one-way channels 101 at intervals, and the inner liner 20 is provided with multiple stops 102 at intervals, with one-way channels 101 and stops 102 corresponding one-to-one.

[0082] The inner circumferential wall of the main body 10 is provided with multiple one-way channels 101 evenly spaced along the circumferential direction. The outer circumferential wall of the inner liner 20 is provided with multiple stops 102 at equal intervals along the circumferential direction corresponding to the positions of the one-way channels 101. The one-way channels 101 and the stops 102 adopt a one-to-one corresponding fit design. The fit of multiple sets of one-way channels 101 and stops 102 helps to improve the assembly stability of the inner liner 20 in the cavity.

[0083] In some embodiments, please refer to Figures 6-9The main body 10 includes a base 110 and an inner sleeve 120. The base 110 has a cavity, a stop 102 is formed in the cavity, the inner sleeve 120 is fixed in the cavity, and the inner sleeve 120 has a channel 121. The channel 121 has a hole K1 that penetrates the inner sleeve 120. The stop 102 is located at the hole K1 and cooperates with the channel 121 to form a one-way channel 101.

[0084] The main body 10 for accommodating the inner liner 20 includes a base 110 and an inner sleeve 120. The base 110 has a shell-like structure. After the inner sleeve 120 is assembled into the cavity of the base 110 along the extension direction of the axis P1, the two are positioned relative to each other by a preset positioning structure. After the base 110 and the inner sleeve 120 are combined to form the main body 10, the stop portion 102 formed in the base 110 can be located in the channel portion 121 of the inner sleeve 120, specifically at the preset hole position K1, so as to cooperate with the channel portion 121 to form a unidirectional channel 101 that can satisfy the unidirectional movement of the sliding portion 201.

[0085] The base 110 adopts a shell-type structure design, and the main body 10 formed by combining with the inner component 120 has the advantage of lightweight, which helps to reduce the overall weight of the main body 10 and improve the convenience of user operation. When the inner component 120 is assembled into the cavity of the base 110 and fixed in a preset direction, the stop part 102 will be located at the preset hole K1 of the channel part 121, thereby cooperating with the channel part 121 to form a one-way channel 101. This split design not only reduces the processing difficulty of the one-way channel 101, but also improves the precision of the key mating parts of the one-way channel 101, so that the inner liner 20 can be combined with the main body 10 more stably.

[0086] For example, the inner peripheral wall of the main body 10 used to define the cavity can be the inner peripheral wall of the inner sleeve 120, and the bottom wall can be the bottom wall of the base 110.

[0087] For example, axis P1 can be the axis of inner kit 120.

[0088] For example, a preset positioning structure refers to a preset assembly structure used to define the relative positions of components.

[0089] In some embodiments, please refer to Figures 6-9 and Figure 11 The base 110 has a protrusion 111, and the stop portion 102 extends along the extension direction of the axis P1 on one side of the protrusion 111. The inner sleeve 120 has a slot 122, and a guide groove 123 is formed on one side of the slot 122. The protrusion 111 and the slot 122 are joined together, and the stop portion 102 passes through the guide groove 123.

[0090] When the inner component 120 is assembled into the cavity of the base 110 along the extension direction of axis P1, the protrusion 111 of the base 110 is simultaneously inserted into the slot 122 of the inner component 120. When the protrusion 111 is stopped by the end of the slot 122, the inner component 120 completes the assembly with the base 110. At this time, part of the stop 102 protrudes into the channel 121 of the inner component 120 and is located at the preset hole position K1. This structure allows the stop 102 to cooperate with the channel 121 to form a one-way channel 101 without the need for deformation by external force. Therefore, it helps to reduce the processing difficulty of the one-way channel 101. At the same time, the double sliding fit system between the protrusion 111 and the slot 122, and between the stop 102 and the guide groove 123, can provide an auxiliary guiding effect for the assembly process of the base 110 and the inner component 120.

[0091] For example, the stop portion 102 extends to one side of the protrusion 111 to form a strip structure.

[0092] For example, the inner peripheral wall of the inner sleeve 120 has an abutment portion 124 formed above the hole K1. When the inner sleeve 120 is fully assembled with the base 110, the end of the stop portion 102 abuts against the abutment portion 124.

[0093] For example, the abutment portion 124 is configured as a bump shape.

[0094] In some embodiments, please refer to Figure 6 and Figure 8 The base 110 is formed with a buckle 112, and the inner sleeve 120 is formed with a buckle claw 125. The buckle 112 and the buckle claw 125 cooperate so that the base 110 and the inner sleeve 120 are combined with each other.

[0095] The inner peripheral wall of the base 110 is integrally formed with multiple fasteners 112 evenly distributed along the circumference. The outer peripheral wall of the inner sleeve 120 is provided with fastener claws 125 that are adapted to the fasteners 112. The fasteners 112 and the fastener claws 125 together form a fastening structure. During the process of assembling the inner sleeve 120 into the cavity of the base 110 along the extension direction of the axis P1, the fastener claws 125 deform under the assembly pressure. When the fasteners 112 slide to the preset snapping position of the fastener claws 125, the fastener claws 125 return to their original position and fasten with the fasteners 112. This fastening structure not only achieves a reliable connection between the base 110 and the inner sleeve 120, but also has a certain degree of assembly convenience, and the two can be quickly combined without additional fasteners.

[0096] For example, a limiting structure is also provided between the base 110 and the inner kit to improve the relative rotation problem that may occur after the two are combined by the fastener 112 and the claw 125. The limiting structure can be a limiting protrusion 126 formed in one of them and a limiting groove 113 formed in the other. After the base 110 and the inner kit 120 are combined, the limiting groove 113 can stop the limiting protrusion 126. Please refer to Figure 5 In this embodiment, the limiting protrusion 126 is formed in the inner sleeve 120, and the limiting groove 113 is formed in the base 110.

[0097] In some embodiments, please refer to Figures 1-2 and Figures 12-13 The main body 10 also includes an outer cover 130, which can cover the base 110.

[0098] To provide multi-dimensional protection for the inner liner 20, the main body 10 is also provided with an outer cover 130. The outer cover 130 and the base 110 form a fitting cover relationship. When the inner liner 20 is assembled into the cavity of the main body 10, the user can use the outer cover 130 to completely cover the cavity opening, thereby preventing external dust, moisture and foreign objects from entering. At the same time, the outer cover 130 can also form a protective barrier to mitigate the impact of external impacts on the inner liner 20.

[0099] For example, the outer cover 130 may be attached to the base 110 by means of snap-fit, thread, or plug-in.

[0100] For example, please refer to Figures 1-2 , Figure 6 and Figures 12-13 In this embodiment, the outer cover 130 is rotatably connected to the base 110 via a pivot structure, enabling the outer cover 130 to open and close relative to the base 110. To mitigate the possibility of the outer cover 130 falling due to its own weight when open, the base 110 has an angled stop portion 114 integrally formed below the pivot hinge position. The stop portion 114 can limit the rotation stroke of the outer cover 130, thereby improving the problem of the outer cover 130 flipping and falling due to gravity when open, and enhancing the user experience.

[0101] For example, the maximum opening angle of the outer cover 130 is limited to 120°-135° by the stop portion 114.

[0102] In some embodiments, please refer to Figure 2 The inner side of the outer cover 130 has a groove 131 for mounting a lens.

[0103] To achieve the versatility of cosmetic containers, the inner side of the outer cover 130 is integrally molded with a groove 131 for fitting lenses. The contour of the groove 131 matches the shape of the lens. During the makeup process, users can directly observe and modify their makeup through the lens embedded in the outer cover 130 without having to carry an additional makeup mirror, which improves the convenience of use.

[0104] In some embodiments, please refer to Figures 12-13 The inner liner 20 includes an inner seat 200 and an inner cover 210, with a sliding portion 201 formed on the inner seat 200 and the inner cover 210 capable of closing onto the inner seat 200.

[0105] The inner liner 20 can be composed of two parts: an inner seat 200 and an inner cover 210. The internal structure of the inner seat 200 is adapted to the needs of cosmetics and can stably support cosmetic substrates of different forms such as creams and dispensed products. The inner cover 210 closes the opening of the inner seat 200 by covering it, which is used to prevent external dust, moisture and other impurities from entering, while reducing the volatilization of cosmetic ingredients.

[0106] For example, the sliding portion 201 may be formed on the outer peripheral wall of the inner seat 200.

[0107] For example, the inner cover 210 can be fitted onto the inner seat 200 by means of snap-fit, thread, or plug-in. In this embodiment, the inner cover 210 is rotatably connected to the inner seat 200 by a rotating shaft.

[0108] For example, in this embodiment, the inner cover 210 is rotatably connected to the inner seat 200 via a pivot structure, enabling the inner cover 210 to open and close relative to the inner seat 200. To mitigate the possibility of the inner cover 210 falling due to its own weight when open, the hinge connection between the inner cover 210 and the inner seat 200 can be designed as a damping structure, providing a moderate damping feel to the opening and closing action of the inner cover 210. This design effectively counteracts the downward tendency of the inner cover 210 without affecting its smooth opening and closing, allowing the inner cover 210 to remain stably at any opening angle, which helps to improve the product's stability and user experience.

[0109] For example, please refer to Figures 1-2 and Figures 12-13 The inner seat 200 is formed by assembling the base shell 220 and the outer sleeve 230, thus constituting a component for supporting the cosmetic substrate. The base shell 220 adopts a shell-type structure, and the sliding part 201 is formed on the outer peripheral wall of the outer sleeve 230. After the outer sleeve 230 is assembled to the outside of the base shell 220 along the extension direction of the axis P1, it forms the inner seat 200 together with the base shell 220.

[0110] For example, please refer to Figure 12 and Figure 13The base shell 220 has an integrally formed annular convex ring 221 at its bottom, while the outer sleeve 230 has an integrally formed annular concave ring 231 at its bottom. The convex ring 221 and the concave ring 231 are mutually compatible. When the base shell 220 and the outer sleeve 230 are assembled, the convex ring 221 can be completely engaged with the concave ring 231. This structure, through the limiting design of the convex and concave fit, effectively restricts the relative displacement between the base shell 220 and the outer sleeve 230, which can enhance the combination stability between the base shell 220 and the outer sleeve 230 and help improve the service life of the overall structure of the inner sleeve 20.

[0111] For example, in this embodiment, the inner cover 210 is rotatably connected to the base shell 220 via a pivot.

[0112] As an exemplary first embodiment, when the inner liner 20 is inserted into the cavity of the main body 10 along the extension direction of the axis P1, the sliding part 201 can enter the one-way channel 101. After the user applies a circumferential torsional force to the inner liner 20, the sliding part 201 will travel along the preset trajectory of the one-way channel 101 and cooperate with the stop part 102 when it passes through it, so that the inner liner 20 is installed in the cavity. If the inner liner 20 is continued to be twisted, the sliding part 201 can continue to travel along the preset trajectory of the one-way channel 101, so that the inner liner 20 can be removed from the cavity. If the inner liner 20 is twisted in the opposite direction, the stop part 102 will interfere with the sliding part 201, thereby restricting the reverse rotation of the inner liner 20.

[0113] As an exemplary second embodiment, when the inner liner 20 is inserted into the cavity of the main body 10 along the extension direction of the axis P1, the sliding part 201 can enter the one-way channel 101. After the user applies a circumferential torsional force to the inner liner 20, the sliding part 201 will travel along the preset trajectory of the one-way channel 101 and cooperate with the stop part 102 when it passes through it, so that the inner liner 20 is installed in the cavity. If the inner liner 20 is continued to be twisted, the sliding part 201 can continue to travel along the preset trajectory of the one-way channel 101, so that the inner liner 20 can be removed from the cavity. If the inner liner 20 is twisted in the opposite direction, the stop part 102 will interfere with the sliding part 201, thereby restricting the reverse rotation of the inner liner 20.

[0114] The one-way channel 101, designed with a U-shaped groove structure, has a first opening 103 and a second opening 104. When the inner liner 20 is inserted into the cavity, the sliding part 201 can enter the one-way channel 101 through the first opening 103. When the sliding part 201 passes the stop part 102 and the user continues to apply a torsional force, the sliding part 201 can continue to travel along a preset trajectory until it reaches the second opening 104. At this time, the sliding part 201 can disengage from the one-way channel 101 through the second opening 104, thereby releasing the constraint of the main body 10 on the inner liner 20.
