Description

Technical Field

[0001] This application relates to the field of cosmetic technology, and more particularly to a self-sealing cosmetic container. Background Technology

[0002] Liquid cosmetics typically have a lighter texture, better spreadability, and better skin integration, creating a natural and radiant makeup look, making them highly popular in the makeup and skincare industries.

[0003] Furthermore, existing liquid cosmetic containers are soft and prone to leakage at the connection between the container and the application device. Also, since the application device cannot be turned off during use, leakage is likely to occur at the application head, affecting the user experience. Utility Model Content

[0004] This application provides a self-sealing cosmetic container to prevent cosmetic leakage from the application device and improve the user experience.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] This application provides a self-sealing cosmetic container, including a container and an application device. The container is used to store cosmetic liquid and has a mounting portion. The application device is mounted on the mounting portion. The application device includes a base and an application assembly. The base is mounted on the mounting portion and includes a mounting cavity and a liquid inlet. The mounting cavity extends at least partially into the container, and the liquid inlet is located at the end of the mounting cavity extending into the container and communicates with the mounting cavity. The application assembly includes a liquid flow channel that extends at least partially into the mounting cavity. The application assembly has a rotational degree of freedom relative to the mounting cavity, such that the liquid flow channel has a connected state communicating with the liquid inlet and a disconnected state misaligned with the liquid inlet. Furthermore, the application assembly includes a flow channel hole, a first sealing ring, and a second sealing ring. The first sealing ring and the second sealing ring abut against the inner wall of the mounting cavity, and the flow channel hole is located between the first sealing ring and the second sealing ring.

[0007] Furthermore, the coating assembly includes a housing and a rotating tube, the rotating tube being at least partially installed within the mounting cavity and having rotational freedom relative to the base; a limiting ring is formed at the end of the housing facing the base, and the housing is installed within the base via the limiting ring.

[0008] Furthermore, the rotating tube includes a flow channel that extends through the rotating tube along its axis. The flow channel hole is located on the side wall of the rotating tube and is connected to the flow channel to form a liquid flow channel. When the liquid flow channel is in a connected state, the flow channel hole is at least partially connected to the liquid inlet hole. When the liquid flow channel is in a disconnected state, the flow channel hole is misaligned with the liquid inlet hole.

[0009] Furthermore, the rotating tube includes a sealing section, with a first sealing ring and a second sealing ring arranged along the axial direction of the rotating tube.

[0010] Furthermore, the base also includes a countersunk hole that communicates with the mounting cavity; the rotating tube at least abuts against the countersunk hole to seal it.

[0011] Furthermore, a rotation limiting groove is formed inside the mounting cavity; a limiting block is formed on the rotating tube, and the limiting block is installed in the rotation limiting groove to limit the rotation angle of the coating component; the rotation limiting groove includes at least one limiting surface; when one side wall of the limiting block abuts against the limiting surface, the liquid inlet hole communicates with the liquid flow channel.

[0012] Furthermore, a connecting plate is formed on the side wall of the rotating tube, and the connecting plate extends radially along the rotating tube; a slot is formed inside the outer casing, and the connecting plate is inserted into the slot so that the outer casing is connected to the rotating tube.

[0013] Furthermore, the application assembly also includes an application head and a connecting pad. The application head is connected to the rotating tube via the connecting pad. The application head extends at least partially to the outside of the housing. The connecting pad abuts against the housing and the rotating tube respectively. An outlet hole is formed inside the application head. A through hole is formed inside the connecting pad. The flow channel hole, flow channel, through hole and outlet hole are connected to form a liquid flow channel.

[0014] Furthermore, the applicator head includes a first surface facing away from the base, and a preset straight line is defined. The preset straight line passes through the lowest point and the highest point of the first surface. Along a direction parallel to the first surface and perpendicular to the preset straight line, the width of the applicator head increases from the lowest point of the first surface to the highest point of the first surface and then decreases.

[0015] Furthermore, the first surface is symmetrical about a preset straight line, and the ratio of the maximum thickness perpendicular to the first surface to the distance between the lowest and highest points of the first surface is 0.15 to 0.35.

[0016] Furthermore, along the direction perpendicular to the first surface, the cross-sectional area of ​​the applicator head parallel to the first surface first increases and then decreases from the side facing the rotating tube toward the first surface.

[0017] Furthermore, a guide surface is formed at the end of the container facing the mounting part, and the liquid inlet hole at least partially intersects with the guide surface and the connection point of the mounting part.

[0018] Furthermore, the base includes an extension for forming a mounting cavity, the extension extending toward the container, and the outer side wall of the extension at least partially abutting against the inner wall of the mounting portion.

[0019] Furthermore, a limiting protrusion is formed on the outer side of the mounting part. The limiting protrusion is connected to the base and restricts the rotation of the base relative to the mounting part, thereby locking the base and the mounting part together.

[0020] Furthermore, the cosmetic container also includes an end cap, which is fitted onto the outside of the application device and is detachably connected to the base. A rotating groove is formed on the base, extending along the rotation direction of the application component, and a snap-fit ​​protrusion is formed within the rotating groove. A snap-fit ​​connector is formed within the end cap. The end cap includes a closed state connected to the application device and an open state separated from the application device. When the end cap is in the closed state, the snap-fit ​​connector is snapped into the rotating groove by the snap-fit ​​protrusion. When the end cap is in the open state, the snap-fit ​​connector is separated from the rotating groove. When the end cap switches from the closed state to the open state, the end cap rotates relative to the base.

[0021] Furthermore, a connecting strip is formed inside the end cap; a connecting groove is formed on the applicator; when the end cap is in the closed state, the connecting strip is inserted into the connecting groove; when the end cap is switched from the closed state to the open state, the connecting strip is inserted into the connecting groove, causing the end cap to drive the applicator to rotate, so that the liquid flow channel is connected to the liquid inlet.

[0022] The base and mounting part are locked together to allow the application assembly to rotate relative to the base, thereby facilitating the adjustment of the liquid flow channel and preventing leakage from the cosmetic container. Attached Figure Description

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as one implementation, this application provides a self-sealing cosmetic container, including a container 6 and an application device. The container 6 is used to store cosmetic liquid. The container 6 has a mounting part 601. The cosmetic liquid stored in the container 6 can be discharged out of the container 6 through the mounting part 601. The application device is installed on the mounting part 601 and is used to apply the cosmetic liquid discharged from the container 6 to the user's skin surface.

[0042] The applicator includes a base 1 and an applicator assembly, the base 1 being used to mount the applicator assembly onto the container 6.

[0043] Specifically, the base 1 is mounted on the mounting part 601. The base 1 includes a mounting cavity 102 and a liquid inlet 101. The mounting cavity 102 extends in a direction away from the applicator head 3 and extends at least partially into the container 6. The liquid inlet 101 is located at the end of the mounting cavity 102 that extends into the container 6 and communicates with the mounting cavity 102, so that the cosmetic liquid in the container 6 can flow into the mounting cavity 102 through the liquid inlet 101.

[0044] A limiting ring 401 is formed at the end of the applicator facing the base 1. The applicator is mounted on the base 1 through the limiting ring 401. The limiting ring 401 provides the applicator with rotational freedom relative to the base 1. At the same time, along the axial direction of the base 1, the limiting ring 401 can limit the applicator on the base 1 to prevent the applicator from falling off the base 1.

[0045] The application component includes a flow channel for the liquid in the container 6 to flow out, through which the liquid flows to the surface of the application component, so that it can be applied to the user's skin surface.

[0046] Furthermore, in the direction of rotation of the applicator relative to the base 1, the base 1 and the mounting part 601 are locked together, that is, the base 1 and the mounting part 601 are fixed so as to drive the applicator to rotate relative to the base.

[0047] The applicator extends at least partially into the mounting cavity 102 and has a rotational degree of freedom relative to the mounting cavity 102, so that the liquid flow channel has a connected state that communicates with the liquid inlet 101 and a disconnected state that is misaligned with the liquid inlet 101, which facilitates the adjustment of the opening and closing of the liquid flow channel and prevents leakage of the cosmetic container.

[0048] When the liquid flow channel is in the connected state, the liquid inlet 101 is connected to the liquid flow channel so that the cosmetic liquid in the container 6 can flow to the surface of the application component so that it can be applied to the user's skin through the application component.

[0049] When the liquid flow channel is disconnected, the liquid inlet 101 is disconnected from the liquid flow channel to prevent the cosmetic liquid in container 6 from flowing out of container 6.

[0050] To more clearly illustrate the technical solution of this application, the following definitions are provided: Figure 1 The vertical direction is shown. The axial direction of base 1 is... Figure 1 The up and down directions in the middle.

[0051] like Figure 4 and Figure 5 As shown, in one implementation, the application assembly includes a rotating tube 2, an application head 3, a housing 4, and a connecting pad 5. The rotating tube 2 is used to deliver the cosmetic liquid in the container 6 to the surface of the application assembly. The housing 4 is used to protect the rotating tube 2. At the same time, the housing 4 can drive the rotating tube 2 to rotate relative to the base 1. The application head 3 is installed at the end of the rotating tube 2 away from the base 1. The connecting pad 5 is connected to the housing 4 and the rotating tube 2 respectively to improve the sealing of the application assembly. The cosmetic liquid in the container 6 flows through the base 1, the rotating tube 2, and the connecting pad 5 in sequence and then flows to the surface of the application head 3, thereby applying and applying makeup to the user's skin surface through the application head 3.

[0052] The rotating tube 2 is at least partially installed in the mounting cavity 102, and the rotating tube 2 has a rotational degree of freedom to rotate relative to the base 1 so that the rotating tube 2 can communicate with the liquid inlet 101.

[0053] The end of the outer shell 4 facing the base 1 forms a limiting ring 401. The outer shell 4 is installed in the base 1 through the limiting ring 401. The rotating tube 2 is limited and installed on the base 1 by the outer shell 4. At the same time, the outer shell 4 can rotate relative to the base 1.

[0054] Furthermore, the outer casing 4 is connected to the rotating tube 2, and the rotating tube 2 can be driven to rotate through the outer casing 4.

[0055] like Figure 4 , Figure 5 and Figure 6As shown, as another implementation, the rotating tube 2 includes a flow channel 201 and a flow channel hole 202. The flow channel 201 passes through the rotating tube 2 along the axis of the rotating tube 2. The flow channel hole 202 is located on the side wall of the rotating tube 2 and is connected to the flow channel 201. The cosmetic liquid in the container flows into the flow channel 201 after passing through the liquid inlet hole 101 and the flow channel hole 202.

[0056] When the applicator is in the applicator state, the liquid inlet 101 is connected to the flow channel 201 through the flow channel hole 202 so that the cosmetic liquid can flow into the flow channel 201.

[0057] When the applicator is in the off state, the flow channel hole 202 is misaligned with the liquid inlet hole 101, and the side wall of the rotating tube 2 abuts against the liquid inlet hole 101.

[0058] It should be noted that the flow channel hole 202 can be an opening at one end of the flow channel 201 facing the base 1, or it can be a through hole formed separately on the side wall of the rotating tube 2. When the flow channel hole 202 is a through hole formed separately on the side wall of the rotating tube 2, the axis of the flow channel hole 202 and the axis of the flow channel 201 are located on the same plane and intersect each other. This application describes the flow channel hole 202 as being formed on the side wall of the rotating tube 2.

[0059] like Figure 5 and Figure 7 As shown, in one implementation, the rotating tube 2 includes a sealing section 208, which is located inside the base 1, and the outer wall of the sealing section 208 abuts against the inner wall of the mounting cavity 102. By setting the sealing section 208, the cosmetic liquid is prevented from flowing out from the gap between the base 1 and the rotating tube 2, thereby improving the sealing performance of the connection between the sealing section 208 and the base 1.

[0060] Furthermore, the flow channel hole 202 is located in the middle of the sealing section 208, ensuring that the cosmetic liquid can flow steadily into the flow channel 201.

[0061] As one implementation, along the axial direction of the rotating tube 2, a first sealing ring 2081 and a second sealing ring 2082 are formed at both ends of the sealing section 208, respectively, and the first sealing ring 2081 and the second sealing ring 2082 abut against the inner wall of the mounting cavity 102.

[0062] The flow channel hole 202 is located between the first sealing ring 2081 and the second sealing ring 2082, ensuring that the cosmetic liquid can flow stably into the flow channel 201, thereby ensuring that the cosmetic liquid can flow continuously and stably to the surface of the applicator head 3.

[0063] like Figure 5 , Figure 8 and Figure 9As shown, in one implementation, the base 1 includes an extension 104 for forming a mounting cavity 102. The extension 104 extends toward the container 6 and at least partially extends into the container 6, such that the mounting cavity 102 extends at least partially into the container 6. An inlet hole 101 is formed in the extension 104 so that the cosmetic liquid flows into the mounting cavity 102 through the cosmetic liquid on the extension 104.

[0064] Furthermore, at least part of the circumferential sidewall of the extension 104 abuts against the inner sidewall of the mounting portion 601, thereby improving the installation seal between the base 1 and the container 6.

[0065] As one implementation, the flow channel hole 202 is formed on the side wall of the rotating tube 2, so that during the rotation of the rotating tube 2 relative to the base 1, the flow channel hole 202 is at least partially connected to the liquid inlet hole 101 located on the extension 104, thereby facilitating the direct flow of cosmetic liquid into the flow channel 201 through the liquid inlet hole 101 and the flow channel hole 202, reducing the amount of cosmetic liquid flowing out of the container during a single use, and further preventing leakage of the application device when it is in the disconnected state.

[0066] like Figure 5 As shown, in one implementation, the flow channel 201 includes a first flow channel section 2011 and a second flow channel section 2012 through which the cosmetic liquid flows sequentially. The inner diameter of the first flow channel section 2011 is larger than the inner diameter of the second flow channel section 2012, and the second flow channel section 2012 is connected to the liquid outlet hole 301, and the flow channel hole 202 is connected to the first flow channel section 2011.

[0067] By reducing the inner diameter of the second flow channel section 2012 connected to the liquid outlet 301, the amount of cosmetic liquid flowing through the flow channel 201 to the application head 3 can be reduced, thereby improving the uniformity of application of this cosmetic container; by setting the first flow channel section 2011, it can be ensured that enough cosmetic liquid can flow into the flow channel 201, ensuring that the flow channel 201 can continuously provide cosmetic liquid to the application head 3.

[0068] It should be noted that the flow channel 201 includes at least two flow channel segments with different inner diameters. This application does not limit the number of flow channel segments with different inner diameters in the flow channel 201.

[0069] like Figure 5 and Figure 10 As shown, as one implementation method, in order to facilitate the alignment of the flow channel hole 202 and the liquid inlet hole 101, a rotation limiting structure is provided between the base 1 and the rotating tube 2. By setting the rotation limiting structure, when the rotating tube 2 rotates relative to the base 1 to a certain extreme position, the flow channel hole 202 and the liquid inlet hole 101 are aligned.

[0070] As one implementation, the rotation limiting structure includes a limiting block 203 and a rotation limiting groove 1021. The limiting block 203 is formed on the circumferential side wall of the rotating tube 2, and the rotation limiting groove 1021 is formed on the circumferential inner wall of the mounting cavity 102. After the base 1 and the rotating tube 2 are assembled, the limiting block 203 is installed in the rotation limiting groove 1021.

[0071] Along the rotation direction of the rotating tube 2, the width of the limiting block 203 is smaller than the width of the rotating limiting groove 1021, so that the limiting block 203 can move relative to the rotating limiting groove 1021, so that the applicator can switch between the applicator state and the disconnected state.

[0072] As one implementation, the rotating limiting groove 1021 includes at least one limiting surface 10211. When one side wall of the limiting block 203 abuts against the limiting surface 10211, the liquid inlet 101 communicates with the flow channel 201. The limiting surface 10211 limits the rotation limit position of the limiting block 203, thereby ensuring that when the limiting block 203 rotates to the limit position, the liquid inlet 101 communicates with the flow channel 201, so that the cosmetic liquid can be delivered to the application head 3.

[0073] It should be noted that the limiting surface 10211 in this application includes two limiting surfaces 10211, which are located on both sides of the rotating limiting groove 1021 along the rotation direction of the rotating tube 2. When one side wall of the limiting block 203 abuts against the limiting surface 10211 on one side, the liquid inlet 101 communicates with the flow channel 201. When the other side wall of the limiting block 203 abuts against the limiting surface 10211 on the other side, the liquid inlet 101 is misaligned with the flow channel 201, thereby closing the flow channel 201.

[0074] As one implementation, the outer shell 4 is connected to the rotating tube 2, so that the rotating tube 2 and the outer shell 4 rotate simultaneously. This allows the outer shell 4 to rotate the rotating tube 2, preventing the user from contacting the rotating tube 2 and preventing the rotating tube 2 from being contaminated. At the same time, it can prevent foreign objects from entering between the base 1 and the rotating tube 2, ensuring that the rotating tube 2 can rotate stably relative to the base 1. It can also prevent foreign objects from contaminating the cosmetic liquid.

[0075] It should be noted that in some other embodiments, the application device may consist only of a base 1, a rotating tube 2, and an application head 3.

[0076] like Figure 7 , Figure 8 and Figure 11 As shown, in one implementation, a connecting plate 204 is formed on the side wall of the rotating tube 2, and the connecting plate 204 extends radially along the rotating tube 2; a slot 403 is formed inside the outer casing 4, and the connecting plate 204 is inserted into the slot 403 so that the outer casing 4 is connected to the rotating tube 2.

[0077] Specifically, the slot 403 extends along the axial direction of the housing 4 so as to facilitate the assembly of the slot 403 with the connecting plate 204 during the installation of the housing 4, thereby facilitating the connection between the rotating tube 2 and the housing 4 and improving the assembly convenience of this coating device.

[0078] As one implementation, an annular support plate 207 is also formed on the circumferential sidewall of the rotating tube 2. The circumferential sidewall of the support plate 207 is clearance-fitted with the inner wall of the outer shell 4 to keep the rotating tube 2 and the outer shell 4 coaxial, further improving the assembly convenience of the rotating tube 2 and the outer shell 4. The connecting plate 204 is connected between adjacent support plates 207 to strengthen the strength of the support plate 207.

[0079] Furthermore, along the radial direction of the rotating tube 2, the length of the connecting plate 204 is greater than the length of the support plate 207, so as to facilitate connection with the outer casing 4 via the connecting plate 204.

[0080] Alternatively, a connecting block 206 is formed at the end of the connecting plate 204 away from the rotating tube 2, and the connecting block 206 is connected to the slot 403 to realize the connection between the rotating tube 2 and the outer shell 4.

[0081] like Figure 5 As shown, as one implementation, the base 1 also includes a countersunk hole 105, which is located above the mounting cavity 102 and is connected to the mounting cavity 102.

[0082] The support plate 207 of the rotating tube 2 at least abuts against the countersunk hole 105, thereby sealing the countersunk hole 105 and further improving the sealing performance of the connection between the rotating tube 2 and the base 1.

[0083] Furthermore, a sealing ring is formed on the lower end surface of the support plate 207 located at the bottom of the rotating tube 2, so as to improve the sealing performance of the connection between the rotating tube 2 and the base 1.

[0084] like Figure 7 and Figure 8 As shown, in one implementation, the end of the rotating tube 2 away from the base 1 has a connecting slope 205. The connecting slope 205 is also connected to the adjacent support plate 207 through a connecting plate 204. The applicator head 3 is installed on the connecting slope 205.

[0085] The connecting slope 205 is inclined relative to the axis of the rotating tube 2, and the inclination angle between the connecting slope 205 and the rotating tube 2 is 30° to 60°. By setting the connecting slope 205 at an inclination, the application head 3 is inclined relative to the axis of the base 1, so that the application head 3 can apply the cosmetic liquid to the user's skin surface and improve the comfort of using this application device.

[0086] As one implementation, the end face of the outer shell 4 facing away from the base 1 is arranged parallel to the connecting slope 205, so that the upper and lower ends of the connecting pad 5 can abut against the connecting slope 205 of the rotating tube 2 and the inner wall of the end face of the outer shell 4 respectively, thereby further improving the sealing performance of this coating device.

[0087] As one implementation, a liquid passage hole 501 is formed on the connecting pad 5. The liquid passage hole 501 is connected to the flow channel 201 and the liquid outlet hole 301 respectively. The flow channel 201, the flow channel hole 202, the liquid passage hole 501 and the liquid outlet hole 301 are connected to form a liquid flow channel.

[0088] Specifically, the inner diameter of the liquid passage 501 is less than or equal to the inner diameter of the second flow channel section 2012, further controlling the amount of cosmetic liquid flowing to the surface of the applicator head 3.

[0089] As one implementation, the applicator head 3 also includes a first surface 302 away from the base 1, and a preset straight line 10 is defined. The preset straight line 10 passes through the lowest point and the highest point of the first surface 302. Along the direction parallel to the first surface 302 and perpendicular to the preset straight line 10, the width of the applicator head 3 increases from the lowest point of the first surface 302 to the highest point and then decreases. By setting the width of the first surface 302 to gradually change, it is easier to improve the user comfort of the applicator head 3 and improve the application uniformity of the applicator head 3.

[0090] As another implementation, the first surface 302 is elliptical. Similarly, the elliptical first surface 302 can improve the comfort of using the applicator head 3 and improve the uniformity of the applicator head 3.

[0091] As one implementation, the first surface 302 is symmetrical about the preset straight line 10. When the applicator 3 is applying the product, its movement direction is perpendicular to the preset straight line 10 or tilted relative to the preset straight line 10. By using the first surface 302 which is symmetrical about the preset straight line 10, the consistency of the product application during the back-and-forth application process of the applicator 3 can be improved.

[0092] As one implementation, the ratio of the maximum thickness of the vertical first surface 302 to the distance between the lowest and highest points of the first surface 302 is 0.15 to 0.35.

[0093] By setting the above, the ratio of the distance between the lowest and highest points of the first surface 302 to the maximum width of the vertical preset straight line of the applicator head 3 is avoided from being too large, which would make the first surface 302 too rounded and improve the applicability of the applicator head 3.

[0094] By setting the above, the ratio of the distance between the lowest and highest points of the first surface 302 to the maximum width of the vertical preset straight line of the applicator head 3 is avoided to be too small, thereby improving the applicator head 3's applicability.

[0095] like Figure 7 , Figure 8 and Figure 10 As shown, in one implementation, an annular groove 103 is formed on the outer circumferential wall of the base 1 facing the outer shell 4; a limiting ring 401 is formed on the inner circumferential wall of the outer shell 4 facing the base 1. After the base 1 and the outer shell 4 are assembled, the limiting ring 401 is installed in the annular groove 103. The outer shell 4 is installed on the base 1 by the cooperation of the limiting ring 401 and the annular groove 103, and the outer shell 4 and the base 1 can rotate relative to each other by the cooperation of the limiting ring 401 and the annular groove 103.

[0096] As one implementation, the end of the outer shell 4 facing away from the base 1 has an opening 402, and at least part of the applicator head 3 extends out of the outer shell 4 through the opening 402 to facilitate the application of the applicator head 3 to the user's skin surface.

[0097] As one implementation, along the direction perpendicular to the first surface 302, the cross-sectional area of ​​the applicator 3 parallel to the first surface 302 first increases and then decreases from the side facing the rotating tube 2 toward the first surface 302.

[0098] Specifically, along the direction perpendicular to the first surface 302, the sidewall of the applicator 3 is arc-shaped, which allows the applicator 3 to simulate the shape of a fingertip, making the touch of the applicator 3 similar to that of a fingertip, thus improving the comfort of using the applicator 3. On the other hand, when the applicator 3 is applying the coating, it will be subjected to a certain amount of pressure and deform towards the rotating tube 2, so that part of the sidewall of the applicator 3 abuts against the end face of the outer shell 4 facing the applicator 3, thereby preventing material accumulation between the applicator 3 and the outer shell 4, and thus improving the cleanliness of the applicator.

[0099] like Figure 5 As shown, in one implementation, a guide surface 602 is formed at the end of the container 6 facing the mounting part 601, and the liquid inlet 101 intersects at least partially with the connection between the guide surface 602 and the mounting part 601, so that the cosmetic liquid in the container 6 flows into the application device and prevents the cosmetic liquid from being wasted.

[0100] like Figure 12 As shown, in one implementation, a connecting ring 6012 is formed on the outer side of the mounting part 601, and a snap-fit ​​ring 107 is formed on the inner wall of the base 1. The maximum outer diameter of the connecting ring 6012 is greater than the minimum inner diameter of the snap-fit ​​ring 107. After the base 1 and the outer shell 4 are assembled, the connecting ring 6012 snaps between the adjacent snap-fit ​​rings 107, thereby axially limiting the base 1 to be installed in the mounting part 601.

[0101] It should be noted that there must be at least one connecting ring 6012, and similarly, there must be at least one snap-fit ​​ring 107. It is only necessary to ensure that after the base 1 and container 6 are installed, at least one snap-fit ​​ring 107 is located below the connecting ring 6012.

[0102] As one implementation, a limiting protrusion 6011 is formed on the outer side of the mounting part 601. The limiting protrusion 6011 extends along the axial direction of the mounting part 601. Correspondingly, a limiting groove 108 is formed on the inner wall of the base 1. After the base 1 and the container 6 are installed, the limiting protrusion 6011 is inserted into the limiting groove 108 of the base 1. Through the cooperation of the limiting protrusion 6011 and the limiting groove 108, the rotation of the base 1 relative to the mounting part 601 is restricted, so as to lock the base 1 and the mounting part 601, thereby preventing the base 1 from rotating relative to the mounting part 601 during the rotation of the rotating tube 2 relative to the base 1, and ensuring the stability of the liquid flow channel when switching between the connected state and the disconnected state.

[0103] like Figure 2 and Figure 13 As shown, in one implementation, the cosmetic container also includes an end cap 7, which is fitted onto the outside of the outer shell 4 and covers the application component, so as to protect the application component. The end cap 7 is detachably connected to the base 1, so that the end cap 7 can be installed on the application device or removed from the application device according to the user's needs, thereby improving the safety of the cosmetic container.

[0104] In one implementation, a rotating slot 106 is formed on the base 1, the rotating slot 106 extends along the axial direction of the base 1, and the rotating slot 106 has an opening at the end facing the end cap 7 so that at least a portion of the end cap 7 can be installed into the rotating slot 106.

[0105] A snap-fit ​​connector 701 is formed inside the end cover 7. When the end cover 7 is closed onto the base 1, the snap-fit ​​connector 701 is installed into the rotating slot 106.

[0106] A snap-fit ​​protrusion 1061 is formed in the rotating slot 106. The snap-fit ​​protrusion 1061 snaps the snap-fit ​​connector 701 into the rotating slot 106, thereby improving the installation stability of the end cover 7 and the base 1.

[0107] The end cap 7 includes a closed state that covers the outer shell 4 and an open state that is separated from the outer shell 4.

[0108] When the end cover 7 is in the closed state, the snap connector 701 is snapped into the rotating slot 106 by the snap protrusion 1061, ensuring that the end cover 7 can be stably installed on the base 1.

[0109] When the end cap 7 is in the open state, the card connector 701 separates from the rotating card slot 106, so that the cosmetic liquid can be applied to the user's skin surface through the application device.

[0110] When the end cap 7 switches from the closed state to the open state, the end cap 7 rotates relative to the base 1 so that the snap connector 701 can be screwed out from the snap groove 1061.

[0111] In one implementation, the end cap 7 is connected to the outer shell 4. During the process of the end cap 7 switching from the closed state to the open state, the end cap 7 can drive the outer shell 4 to rotate relative to the base 1, thereby causing the coating component to rotate relative to the base 1, thus opening the liquid flow channel.

[0112] Furthermore, when the end cap 7 is in the closed state, the fluid flow channel is in the open state.

[0113] When the end cap 7 is in the open state, the fluid flow channel is in the open state.

[0114] In one implementation, a connecting strip 702 is formed inside the end cover 7, and the connecting strip 702 extends along the axial direction of the end cover 7; a connecting groove 404 is formed on the outer shell 4, and the connecting groove 404 extends along the axial direction of the outer shell 4; when the end cover 7 is closed on the base 1, the connecting strip 702 is inserted into the connecting groove 404.

[0115] When the end cap 7 is in the closed state, the connecting strip 702 is inserted into the connecting groove 404. At the same time, since the snap-fit ​​connector 701 is snapped into the rotating slot 106 through the snap-fit ​​protrusion 1061, the liquid flow channel is in the open state.

[0116] When the end cap 7 is in the open state, the connecting strip 702 separates from the connecting groove 404, and the snap connector 701 separates from the rotating snap groove 106.

[0117] When the end cap 7 switches from the closed state to the open state, the connecting strip 702 is inserted into the connecting groove 404, causing the end cap 7 to drive the outer shell 4 to rotate, so that the liquid flow channel is connected to the liquid inlet 101.

[0118] As one implementation method, the minimum inner diameter of the location of the snap connector 701 is greater than or equal to the maximum outer diameter of the outer shell 4, so as to prevent the snap connector 701 from interfering with the outer shell 4 during the separation of the end cover 7 from the base 1.

[0119] like Figure 1 As shown, as one implementation method, the cosmetic container also includes a decorative cap 8, which is fitted onto the outside of the end cap 7 to improve the overall aesthetics of the cosmetic container.
