DETAILED DESCRIPTION

[0033] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0034] Combine Figure 1 、 2 As shown, this embodiment provides a cosmetic container, comprising a long tube 1, a lifting assembly 2, a pressure member 3, an upper cover 6, and an inner plug 7. The long tube 1 has a hollow accommodating chamber; the pressure member 3 is slidably disposed in the accommodating chamber and, together with the inner wall of the long tube 1, forms a liquid storage chamber for storing cosmetics; the lifting assembly 2 is coaxially assembled to the bottom end of the cover accommodating chamber and is used to drive the pressure member 3 to vertically lift and lower within the accommodating chamber; the upper cover 6 is mounted on the upper end of the long tube 1, and a slot is formed on the top surface of the upper cover 6; the inner plug 7 is assembled in the slot, and a liquid outlet is formed on the top surface of the inner plug 7. In particular, the inner plug 7 is made of rubber. When the cosmetic container of this embodiment is used, the lifting assembly 2 lifts the pressure member 3 upward. At this time, the cosmetics in the liquid storage chamber above the pressure member 3 are pressed out of the liquid outlet under the action of pressure for use by the user. Because the liquid outlet on the inner plug 7 is small and made of rubber, it remains closed when there is no pressure, effectively preventing moisture and bacteria from entering through the outlet. When pressure is applied, the outlet on the inner plug 7 opens, forcing the cosmetics out. In summary, the arrangement of the lifting assembly 2, the pressurizing member 3, and the inner plug 7 in this embodiment of the cosmetic container provides a more airtight seal, effectively protecting the active ingredients of the cosmetics from being destroyed.

[0035] Furthermore, a liquid reservoir 31 is recessed in the middle of the pressurizing member 3. The inner plug 7 is configured to fit within the reservoir 31, allowing it to be inserted into the reservoir 31 when the pressurizing member 3 is raised to the top surface of the upper cover 6. Because liquids tend to flow from high to low, the reservoir 31 collects any remaining cosmetics in the liquid storage chamber above the pressurizing member 3. The coordinated arrangement of the inner plug 7 and the reservoir 31 maximizes the utilization of the cosmetics within the container, minimizing resource waste.

[0036] Specific, combined Figure 3 、 4 As shown in Figures 5 and 6, the lifting assembly 2 includes a first component 21, a second component 22, and a third component 23. The first component 21 is cylindrical, and its lower end face is coaxially assembled to the lower end face of the long cylinder 1, so that the first component 21 can rotate synchronously with the long cylinder 1, that is, the long cylinder 1 rotates and the first component 21 rotates synchronously with it. The second component 22 is a double-sleeve structure with an open lower end, including an inner cylinder 221 and an outer cylinder 222. The inner cylinder 221 and the outer cylinder 222 are coaxially arranged on both sides of the first component 21, that is, the inner cylinder 221 is located on the inner side of the first component 21, and the outer cylinder 222 is located on the outer side of the first component 21. The third component 23 is cylindrical and coaxially sleeved on the outer wall of the outer cylinder 222. In particular, a first external thread 211 is convexly provided on the outer wall of the first component 21, and a first internal thread 2221 is convexly provided on the inner wall of the outer cylinder 222. The first external thread 211 and the first internal thread 2221 are matched so that when the first component 21 rotates relative to the second component 22, the second component 22 can be vertically lifted and lowered; a second external thread 2222 is convexly provided on the outer wall of the outer cylinder 222, and a second internal thread 231 is convexly provided on the inner wall of the third component 23. The second external thread 2222 and the second internal thread 231 are matched so that when the outer cylinder 222 rotates relative to the third component 23, the third component 23 can be vertically lifted and lowered.

[0037] Further, combined Figure 8As shown, the cosmetic container of this embodiment also includes a lower cover body 4, which is rotatably mounted on the lower end of the long tube 1. The lower end surface of the lower cover body 4 is provided with a protrusion 41 axially upwardly projecting. The protrusion 41 is inserted into the inner tube 221. The outer wall of the protrusion 41 is vertically provided with a plurality of first ridges 411, and the inner wall of the inner tube 221 is vertically provided with a plurality of first grooves 2211. The first ridges 411 are inserted into the first grooves 2211 and can slide vertically relative to the first grooves 2211. The provision of the protrusion 41 in this embodiment serves as a guide, allowing the second member 22 to be vertically raised and lowered along the protrusion 41. In addition, the provision of the first ridges 411 and the first grooves 2211 is used to restrict the circumferential rotation of the second member 22. As a result, when the long tube 1 rotates, it drives the first member 21 to rotate together with the long tube 1. Since the second member 22 cannot rotate circumferentially, the rotation of the first member 21 drives the second member 22 to be vertically raised and lowered.

[0038] Further, combined Figure 5 As shown, a protruding ring 233 is provided on the upper edge of the outer wall of the third member 23. The protruding ring 233 is adapted to support the pressure member 3. The opposite side of the protruding ring 233 is configured as a straight surface 2331, which is used to limit the rotation of the third member 23. Therefore, when the third member 23 and the second member 22 rise to the top of the first member 21 together, that is, the first internal thread 2221 rises to the top of the first external thread 211, the second member 22 cannot continue to rise and will rotate with the rotation of the first member 21. Since the third member 23 cannot rotate circumferentially, the rotation of the second member 22 will drive the third member 23 to rise vertically.

[0039] In summary, in this embodiment, the arrangement of the first component 21, the second component 22 and the third component 23 enables the lifting assembly 2 to achieve two-stage lifting, thereby reducing the height requirement of the cosmetic container; in addition, the double-sleeve structure of the second component 22 makes the structure of the lifting assembly 2 more stable and compact, thereby avoiding the container from getting stuck during use and improving user satisfaction.

[0040] Further, combined Figure 6 As shown, to further stabilize the structure of the lifting assembly, a connecting member 5 is coaxially disposed on the outer wall of the third member 23 in this embodiment. The connecting member 5 is hollow and cylindrical, and its inner wall abuts against the third member 23, allowing the third member 23 to move relative to the connecting member 5. The outer wall of the connecting member 5 is fixedly connected to the inner wall of the long tube 1, and the lower end of the connecting member 5 is assembled to the lower end surface of the long tube 1. The connecting member 5 fills the space between the third member 23 and the long tube 1 to prevent the third member 23 from shaking during movement.

[0041] Furthermore, the inner wall of the connecting member 5 is provided with a plurality of second ridges 51 extending vertically, and the outer wall of the third member 23 is provided with a plurality of second grooves 232 extending vertically. The second ridges 51 engage with the second grooves 232, allowing the third member 23 to be vertically raised and lowered relative to the connecting member 5. The arrangement of the second ridges 51 and the second grooves 232 ensures that the third member 23 can only be raised and lowered vertically along the second grooves 232, preventing the third member 23 from sliding circumferentially relative to the second member 22 while being raised and lowered vertically, which could affect the liquid output of the container.

[0042] Further, combined Figure 7 、 8 As shown, the lower end surface of the lower cover body 4 is circumferentially provided with a slide groove 42 in an upward direction, and the lower end surface of the long tube 1 is circumferentially provided with a plurality of elastic members 11 in a downward direction. The elastic members 11 are arranged correspondingly to the slide grooves 42, so that the elastic members 11 can slide unidirectionally relative to the slide grooves 42. Therefore, when the long tube 1 rotates relative to the lower cover body 4, the elastic members 11 will slide relative to the slide grooves 42. Since the slide grooves 42 are arranged at equal intervals around the lower end surface of the lower cover body 3, each time the slide grooves 42 are passed, the liquid in the liquid storage cavity will be pressed out in equal amounts, which can effectively control the liquid output of the container. In addition, the arrangement of the slide grooves 42 can also control the rotation of the long tube 1, so that the long tube 1 can only rotate in one direction.

[0043] Further, combined Figure 9-11 As shown, the cosmetic container of this embodiment can be a single-ended cosmetic container or a double-ended cosmetic container. The double-ended cosmetic container includes two cosmetic containers and a connecting sleeve 8. The lower covers 4 of the two cosmetic containers are fixedly connected by the connecting sleeve 8. This arrangement allows different liquids to be stored in the two cosmetic containers, making it convenient for users to carry them when traveling.

[0044] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
