[0009] In one embodiment, the lower end face of the annular step is an arc-shaped surface.

[0010] In one embodiment, the upper end of the brush bar is provided with a guide groove extending from the end to the middle section for directional assembly with the cap; In one embodiment, the guide groove is further provided with a first limiting buckle near its end, and the cap has a through hole in the middle, with a second limiting buckle on the inner wall of the through hole that cooperates with and connects to the guide groove.

[0011] In one embodiment, the inner wall of the lower cover is also embedded with a makeup tube for containing makeup liquid; the makeup tube is snapped into the connecting tube.

[0012] In one embodiment, the lower end of the brush tube is provided with a insertion hole for assembling a brush head dipped in makeup liquid.

[0013] The aforementioned retractable lip gloss bottle has the following beneficial effects: This invention achieves structural stability and a liquid-sealing effect by setting an inner cover assembly between the upper and lower covers, and incorporating an abutment ring within the inner cover assembly. This abuts the end face of the inner cover with the connecting pipe opening of the lower cover. A spring is sleeved on the upper end of the brush rod, forming a telescopic mechanism between the inner wall of the upper cover and the brush rod. When the upper and lower covers are separated, the spring releases, pushing the brush rod downwards so that the brush head can fully contact the remaining lip gloss liquid at the bottom of the bottle, improving liquid utilization. When the covers are closed, the spring is compressed, the brush rod retracts, and the end face of the abutment ring abuts with the opening of the connecting pipe, maintaining a sealed bottle. This structure not only solves the problem of existing fixed brush rods failing to completely remove liquid from the bottom of the bottle, but also features a simple overall design, fewer parts, lower processing costs, convenient assembly, and high reliability, making it suitable for various lip makeup products.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] A retractable lip gloss bottle, such as Figures 1-3 The aforementioned components include an upper cover 1, a lower cover 2, an inner cover assembly 3, a brush rod 4, and a spring 5. The upper cover 1 and the lower cover 2 are connected together; the inner cover assembly 3 is nested on the inner wall of the upper cover 1; the upper end of the brush rod 4 is engaged with the inner cover assembly 3; the spring 4 changes the extension length of the brush rod 3 by telescoping or extending. Spring 5 is sleeved on the upper end of brush rod 4, and the upper end of spring 5 abuts against the inner wall of upper cover 1. The inner cover assembly 3 includes an abutment ring 301, and the lower cover 2 is provided with a connecting tube 6. When the upper cover 1 and the lower cover 2 are closed, the end face of the abutment ring 301 abuts against the opening of the connecting tube 6.

[0026] Spring 5 is sleeved on the upper end of brush rod 4 and forms a telescopic mechanism between the inner wall of upper cover 1 and brush rod 4. When upper cover 1 is separated from lower cover 2, spring 5 is released to push brush rod 4 downward, so that brush head can fully contact the residual lip gloss liquid at the bottom of the bottle and improve liquid utilization. When the cover is closed, spring 5 is compressed and brush rod 4 is retracted. At this time, the end face of abutment ring 301 abuts against the opening of connecting tube 6 to keep the bottle closed and sealed, preventing liquid leakage when inverted.

[0027] Specifically, such as Figures 4-5 The inner cover assembly 3 also includes a cap 302. Both the connecting pipe 6 and the inner wall of the cap 302 are provided with connecting threads, and the connecting pipe 6 and the cap 302 are threadedly connected.

[0028] Specifically, the inner side of the cap 302 is provided with a first buckle 3021 and the outer side is provided with a second buckle 3022; the first buckle 3021 is fastened to the connecting tube 6; the second buckle 3022 is fastened to the upper cover 1.
