[0029] 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 are within the scope of protection of the present invention.

[0030] See also Figure 1-8 The utility model provides a technical solution: a non-rotatable lipstick tube, comprising a lower shell 1 and an inner tube 13 installed inside the lower shell 1, wherein a cup 3 for holding lipstick paste is vertically slidably connected inside the inner tube 13; a base 5 is installed on the bottom of the lower shell 1, and a driving member for driving the cup 3 to slide vertically is provided between the base 5 and the cup 3; a carrying tube 7 is provided on the inner tube 13, and a rotation-stopping component is provided between the base 5 and the carrying tube 7 to prevent the base 5 from rotating; an upper shell 2 is installed on the lower shell 1.

[0031] Specifically, the non-rotatable lipstick tube includes a lower shell 1 and an inner tube 13 installed inside the lower shell 1. A cup 3 for holding the lipstick paste is vertically slidably connected inside the inner tube 13. Therefore, during use, when the lipstick needs to be used, the cup 3 drives the lipstick paste to slide upward, so that the lipstick paste can be used after it slides to a predetermined position. A base 5 is installed on the bottom of the lower shell 1, and a driving member for driving the cup 3 to slide vertically is provided between the base 5 and the cup 3, which facilitates the vertical sliding of the lipstick paste. A carrying tube 7 is provided on the inner tube 13, and a rotation-stopping component is provided between the base 5 and the carrying tube 7 to prevent the base 5 from rotating. An upper shell 2 is installed on the lower shell 1 to protect the lipstick paste. When using the lipstick, the base 5 is driven to rotate relative to the inner tube 13. During the rotation of the base 5, the driving member drives the cup 3 to slide upward. After the lipstick slides to a predetermined position, the anti-rotation member locks the base 5, preventing reverse rotation. That is, the lipstick cannot retract into the lipstick tube, so the user can use it for a long time, meeting work needs. After using the lipstick, the upper shell 2 is clamped into the lower shell 1, sealing the lipstick and protecting the lipstick, thereby further improving the practicality of the lipstick tube.

[0032] In the embodiment provided by the present invention, the driving member includes a vertically slidably connected driving rod 4, which is provided with an external thread 8. The base 5 is internally provided with an internal thread 6, which is threadably connected to the external thread 8. Specifically, the internal thread 6 is adapted to the external thread 8 and has a small pitch. Therefore, as the base 5 rotates, the lipstick paste slides upward slowly, thereby preventing the lipstick paste from sliding out completely, further protecting the lipstick paste.

[0033] In the embodiment provided by the present invention, a limiting plate 11 is fixedly connected to the supporting cylinder 7, and an abutment groove is provided on the driving rod 4. When the driving rod 4 slides vertically, the limiting plate 11 abuts against the abutment groove. Specifically, the abutment groove is a planar groove, which can further improve the stability of the driving rod 4 when sliding vertically and avoid the driving rod 4 from rotating.

[0034] In the embodiment provided by the present invention, the anti-rotation component includes multiple sets of abutment plates 10 distributed in a circular array on the inner side of the carrier tube 7. A mounting ring 9 is fixedly connected to the base 5, which is provided with elastic protrusions 15. The elastic protrusions 15 intermittently abut the anti-rotation plates. Multiple sets of locking grooves 14 are formed between the multiple sets of abutment plates 10, and the protrusions intermittently abut within the locking grooves 14. The locking grooves 14 are wedge-shaped on one side, and the elastic protrusions 15 fit into the locking grooves 14. Therefore, when the elastic protrusions 15 are engaged in the locking grooves 14, the base 5 cannot rotate in the reverse direction and can only rotate in the forward direction, driving the lipstick paste upward. Furthermore, because the elastic protrusions 15 intermittently abut the abutment plates 10, a "clicking" sound is produced when the base 5 rotates, enhancing the feel during use and providing a better effect.

[0035] In the embodiment provided by the present invention, fastening plates for fastening the lipstick paste are provided on the support cup 3, and multiple groups of fastening plates are distributed in a circular array inside the support cup 3, thereby improving the stability of the lipstick paste during installation.

[0036] In the embodiment provided by the present invention, a plurality of anti-slip stripes 12 are provided on the upper side of the base 5 to facilitate the rotation of the base 5 and further enhance the feel of use.

[0037] In the embodiment provided by the present invention, a clamping member is provided between the upper shell 2 and the lower shell 1. The upper shell 2 is mounted on the lower shell 1 via the clamping member. An elastic clip is fixedly connected to the inner side of the upper shell 2. An annular clip groove is provided on the circumference of the lower shell 1. When the upper shell 2 is mounted on the lower shell 1, the elastic clip engages in the annular clip groove. This further improves the stability of the upper shell 2 and the lower shell 1 during installation and protects the lipstick paste.

[0038] Specifically, an NBR rubber ring is provided between the upper shell 2 and the lower shell 1 to achieve a sealing effect, thereby preventing the lipstick paste from deteriorating and achieving a better use effect.
