Description

Technical Field

[0001] This utility model relates to a cosmetic container, specifically a lipstick tube. Background Technology

[0002] In the cosmetics industry, lipstick is a common and popular lip care and beautification product, and the design of its packaging container is crucial for user experience and product protection. Traditional lipstick tube designs are usually quite simple, mainly consisting of three parts: a base, a shell, and a protective cap. The lipstick is pushed out or pulled back from the shell by rotating or pushing / pulling.

[0003] Rotary lipstick tubes are typically suitable for cylindrical lipstick tubes. However, for flat, rectangular lipstick tubes, the rotary design often struggles to adapt to their unique shape. Therefore, push-pull lipstick tubes are more commonly used in the market. Push-pull lipstick tubes control the extension and retraction of the lipstick by directly pushing or pulling the shell or base. While the structure is relatively simple, it has a significant drawback: compared to rotary lipstick tubes, push-pull operation is often more strenuous. This is because push-pull lipstick tubes require overcoming greater friction and potential jamming to ensure smooth application and retraction of the lipstick, impacting the user experience. Therefore, designing a rotary lipstick tube specifically for flat, rectangular lipstick tubes is a research direction sought by those in this field. Utility Model Content

[0004] In view of the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a lipstick tube.

[0005] The technical solution of this utility model is: a lipstick tube, including a base, a shell, and a protective cap. The protective cap is snapped onto the upper end of the base and covers the shell. The upper end of the base is rotatably connected to the lower end of the shell. A lipstick holder is placed inside the shell. The lower end of the lipstick holder has a vertically extending screw. A threaded sleeve is fitted onto the screw. The threaded sleeve is threadedly engaged with the screw. The lower end of the threaded sleeve has a rotating seat, which is fixedly connected to the base. The shell has an upward-opening receiving groove. A first magnet is installed at the bottom of the receiving groove. A second magnet that attracts the first magnet is installed in the upper end of the base.

[0006] Furthermore, the upper inner side of the base has a ring-shaped buckle, and the lower outer side of the housing has a ring-shaped groove. The buckle is inserted into the groove and rotates with it.

[0007] Furthermore, the outer side of the screw has a helical groove, and two threaded blocks are protruding on the inner wall of the upper end of the screw sleeve. The threaded blocks are engaged with the helical groove.

[0008] Furthermore, the lower end of the housing has a through hole running vertically through the middle, through which the threaded sleeve passes.

[0009] Furthermore, multiple protrusions are provided on the outer wall of the middle part of the threaded sleeve, and the protrusions rest against the bottom surface of the receiving groove.

[0010] Furthermore, the bottom of the receiving groove has a first mounting groove with an upward opening on both the left and right sides, and there are two first magnets, with one first magnet inserted into each of the two first mounting grooves.

[0011] Furthermore, the upper end of the base has a second mounting slot with an opening facing downward on both the left and right sides. There are two second magnets, and one second magnet is inserted into each of the two second mounting slots.

[0012] The advantages of using the lipstick tube provided by this utility model are: when using it, the protective cap can be removed, the base can be rotated, the base drives the rotating seat to rotate, so that the screw sleeve can rotate. Through the threaded engagement between the screw sleeve and the screw rod, the screw rod can move up and down, thus allowing the lipstick holder to move up and down, which is more convenient to use.

Detailed Implementation

[0018] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0019] like Figure 1 — Figure 4As shown, the lipstick tube includes a base 1, a housing 2, and a protective cap 3. The protective cap 3 is snapped onto the upper end of the base 1 and covers the housing 2. The upper end of the base 1 is rotatably connected to the lower end of the housing 2. A lipstick holder 4 is placed inside the housing 2 to hold lipstick (not shown in the figure). The lower end of the lipstick holder 4 has a vertically extending screw 41, and a threaded sleeve 5 is fitted onto the screw 41. The threaded sleeve 5 is threadedly engaged with the screw 41. The lower end of the threaded sleeve 5 has a rotating seat 51, which is fixedly connected to the base 1. The housing 2 has an upward-opening receiving groove 21. A first magnet 6 is installed at the bottom of the receiving groove 21. A second magnet 7, which is attracted to the first magnet 6, is installed in the upper end of the base 1. The housing 2 is a flat cuboid.

[0020] like Figure 2 As shown, the upper inner side of the base 1 has a ring-shaped buckle 11, and the lower outer side of the housing 2 has a ring-shaped groove 22. The buckle 11 is inserted into the groove 22 and rotates with the groove 22.

[0021] like Figure 3 As shown, the outer side of the screw 41 has a spiral groove 411, and two threaded blocks 52 are protruding on the inner wall of the upper end of the screw sleeve 5. The threaded blocks 52 are inserted into the spiral groove 411 and cooperate with the spiral groove 411.

[0022] like Figure 2 As shown, in order to facilitate the installation of the screw sleeve 5, the lower end of the housing 2 has a through hole 23 that runs vertically through it, and the screw sleeve 5 passes through the through hole 23.

[0023] like Figure 4 As shown, in order to limit the movement of the threaded sleeve 5, a plurality of protrusions 53 are provided on the outer wall of the middle part of the threaded sleeve 5, and the protrusions 53 rest against the bottom surface of the receiving groove 21.

[0024] like Figure 1 As shown, to facilitate the installation of the first magnet 6, the bottom of the receiving groove 21 has an upward-facing first mounting groove 211 on both the left and right sides. There are two first magnets 6, and one first magnet 6 is inserted into each of the two first mounting grooves 211. To facilitate the installation of the second magnet 7, the upper interior of the base 1 has a downward-facing second mounting groove 12 on both the left and right sides. There are two second magnets 7, and one second magnet 7 is inserted into each of the two second mounting grooves 12. The arrangement of the first magnet 6 and the second magnet 7 is to ensure a more reliable connection between the base 1 and the housing 2.

[0025] The lipstick tube provided by this utility model can be used by removing the protective cap 3 and rotating the base 1. The base 1 drives the rotating seat 51 to rotate, so that the screw sleeve 5 can rotate. Through the threaded engagement between the screw sleeve 5 and the screw 41, the screw 41 can move up and down, thereby allowing the lipstick holder 4 to move up and down, which is more convenient to use.

[0026] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
