DETAILED DESCRIPTION

[0030] 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.

[0031] Combine Figure 1 、 2 As shown, this embodiment provides a cosmetic container, including a long tube 1, a lifting assembly 2 and a pressurizing member 3. The long tube 1 has a cylindrical accommodating cavity, and the lifting assembly 2 is coaxially arranged at the bottom end of the accommodating cavity; the pressurizing member 3 is located above the lifting assembly 2, and its outer wall abuts against the inner wall of the long tube 1, and together with the long tube 1 forms a liquid storage cavity for storing liquid; in particular, the pressurizing member 3 can be vertically lifted and lowered under the drive of the lifting assembly 2, thereby pressing the liquid in the liquid storage cavity upward.

[0032] 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.

[0033] Further, combined Figure 8As shown, the cosmetic container of this embodiment further includes a lower cover 4, which is rotatably mounted on the lower end of the long tube 1. A protrusion 41 is axially upwardly projecting from the lower end surface of the lower cover 4. The protrusion 41 is movably inserted into the inner tube 221. The protrusion 41 serves as a guide, allowing the second member 2 to be vertically raised and lowered along the protrusion 41, thereby preventing the second member 22 from tilting during the raising and lowering process.

[0034] Furthermore, the outer wall of the protruding column 41 is vertically provided with a plurality of first ridges 411, and the inner wall of the inner cylinder 221 is vertically provided with a plurality of first grooves 2211. The first ridges 411 are slidably inserted into the first grooves 2211. The arrangement of the first ridges 411 and the first grooves 2211 is used to limit the circumferential rotation of the second member 22, so that the second member 22 can only be vertically lifted and lowered along the first grooves 2211. Thus, when the long tube 1 rotates, it will drive the first member 21 to rotate together with the long tube 1. Since the arrangement of the first ridges 411 and the first grooves 2211 limits the circumferential rotation of the second member 22, the rotation of the first member 21 will drive the second member 22 to rise along the first grooves 2211 to the top of the first member 21, completing the first stage of lifting. It should be noted that since there is no relative rotation between the second member 22 and the third member 23 during the first stage of lifting, the second member 22 will drive the third member 23 to be lifted and lowered synchronously while being lifted and lowered vertically.

[0035] 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 pressurizing member 3. In addition, the opposite side of the protruding ring 233 is configured as a straight surface 2331, which is used to limit the circumferential rotation of the third member 23. Thus, 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 provision of the straight surface 2331 limits the circumferential rotation of the third member 23, the rotation of the second member 22 will drive the third member 23 to move vertically upward and downward, thereby completing the second stage of lifting.

[0036] 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.

[0037] Further, combined Figure 6As shown, in order to make the structure of the lifting assembly more stable, a connecting member 5 is coaxially arranged between the third member 23 and the long tube 1 in this embodiment, and the lower end of the connecting member is assembled on the lower end surface of the long tube 1. In this embodiment, the connecting member 5 is filled between the third member 23 and the long tube 1 to prevent the third member 23 from shaking during movement.

[0038] 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 are inserted into the second grooves 232, allowing the third member 23 to be vertically raised and lowered relative to the connecting member 5. The provision of the second ridges 51 and the second grooves 232 allows the third member 23 to be vertically raised and lowered along the second grooves 232, preventing the third member 23 from sliding circumferentially relative to the second member 22 during vertical raising and lowering, which could affect the liquid output of the container.

[0039] Furthermore, the upper end of the long tube 1 of this embodiment is sleeved with an upper cover 6, and the upper end surface of the upper cover 6 is provided with a liquid outlet, allowing the liquid in the liquid storage chamber to flow out through the liquid outlet. The liquid outlet is equipped with an inner plug 7, which is made of rubber and has a cross-shaped liquid outlet hole at its top. When the cosmetic container of this embodiment is in use, the pressure member 3 is lifted upward by the lifting assembly 2. 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 the user to use. Because the liquid outlet of the inner plug 7 is small and made of rubber, when there is no pressure, the liquid outlet of the inner plug 7 is in a closed state, thus effectively isolating the liquid outlet from moisture and bacteria in the air. When pressure is applied, the liquid outlet of the inner plug 7 is stretched open, thereby forcing the cosmetics out. In summary, the arrangement of the lifting assembly 2, the pressure member 3, and the inner plug 7 of this embodiment makes the cosmetic container more sealed, effectively protecting the active ingredients of the cosmetics from oxidation.

[0040] Further, combined Figure 7 、 8 As shown, a chute 42 is circumferentially arranged upward on the lower end surface of the lower cover 4, and a plurality of elastic members 11 are circumferentially arranged downward on the lower end surface of the long tube 1. The elastic members 11 are arranged correspondingly to the chute 42, so that the elastic members 11 can slide unidirectionally relative to the chute 42. Therefore, when the long tube 1 rotates relative to the lower cover 4, the elastic members 11 will slide unidirectionally relative to the chute 42. Since the chute 42 is evenly arranged on the lower end surface of the lower cover 3, the amount of liquid discharged from the container can be well controlled. In addition, the arrangement of the chute 42 can also control the rotation of the long tube 1, so that the long tube 1 can only rotate in one direction.

[0041] Further, combined Figure 9-11As 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.

[0042] 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.
