Modes for Carrying Out the Invention

[0014] Hereinafter, while combining the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0015] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the purpose of easily and simply explaining the present invention, and does not indicate or imply that the shown device or component must have a specific orientation, be configured and operated in a specific orientation, so it should not be understood as a limitation to the present invention.

[0016] The paste stirring and mixing structure of the cosmetic bottle disclosed by the present invention is mainly applied to the scene where the cosmetic bottle does not have a stirring function.

[0017] Referring to FIGS. 1 to 5, it is a cosmetic bottle paste stirring and mixing structure, including a bottle body 1, with cosmetic paste filled inside the bottle body 1. A thread 2 is installed at the upper end opening of the bottle body 1. A cap assembly is connected to the upper end of the bottle body 1. The cap assembly is composed of an outer cap 3, an inner cap 4, and an elastic rotation structure. The outer cap 3 is fixed to the inner cap 4, and the inner cap 4 is screwed onto the thread 2. A stirring component penetrates through the bottle body 1 and the inner cap 4. The elastic rotation structure is installed inside the inner cap 4. The elastic rotation structure is used to drive the stirring component to reciprocally rotate to stir and mix the cosmetic paste. The elastic rotation structure includes a large spring 8 fitted at the upper end of the stirring component. A lifting seat 9 is connected to the upper end of the large spring 8. A button 12 is elastically connected to the upper end of the outer cap 3. The button 12 is used to drive the lifting seat 9 to move downward. The lifting seat 9 does not rotate during movement and is screwed onto the upper end of the stirring component.

[0018] In this embodiment, before using this cosmetic bottle, the button 12 can be pressed downward with a finger, and the button 12 can press the lifting seat 9 in the inner cap 4. Since the lifting seat 9 is screwed to the stirring component, the stirring component rotates. Thereby, the cosmetic paste inside the bottle body 1 is stirred. And when the hand is released, the elastic force of the large spring 8 can drive the lifting seat 9 to rise again, whereby the stirring component can rotate reversely again, further stirring the cosmetic paste. After uniformly stirring, the outer cap 3 can be rotated, and the outer cap 3 can remove the inner cap 4 from the bottle body 1 to facilitate cosmetic application.

[0019] Specifically, the stirring component includes a shank 5, a screw end 7 is installed at the upper end of the shank 5, the screw groove on the outer wall of the screw end 7 contacts the inner protrusion 10 on the inner wall of the lifting seat 9, and by the pressing between the inner protrusion 10 and the screw groove, the shank 5 is rotated. The outer protrusion 18 on the outer wall of the lifting seat 9 is slidably connected to the stopper groove 19 on the inner wall of the inner cap 4. In the process of the lifting seat 9 moving up and down, the stopper groove 19 on the inner wall of the inner cap 4 can limit the position of the outer protrusion 18 and the lifting seat 9 to prevent the occurrence of its rotation.

[0020] Furthermore, a brush head 14 is installed at the lower end of the shank 5, and the brush head 14 is used for applying cosmetics.

[0021] Specifically, as shown in FIG. 3, a rib 13 is installed at a position between the screw end 7 and the brush head 14 of the shank 5, a stirring ring 15 is placed inside the bottle body 1, and the rib 13 is engaged with the concave groove 16 on the inner wall of the stirring ring 15. In the process of the shank 5 rotating, the rib 13 can rotate the stirring ring 15, thereby improving the stirring uniformity of the cosmetic paste.

[0022] Here, as shown in FIG. 4, a plurality of stirring blades 17 are installed on the outer peripheral surface of the stirring ring 15.

[0023] Furthermore, a sealing ring 6 is installed between the shank 5 and the inner cap 4 to prevent the cosmetic paste from penetrating into the inner cap 4.

[0024] Specifically, a small spring 11 is installed between the button 12 and the screw end 7, and the small spring 11 is used to provide return elasticity to the button 12. The small spring 11 can rotate along with the screw end 7.

[0025] The operating principle is as follows. Before using the cosmetics, press the button 12 down with your finger. The button 12 can press the lifting seat 9 in the inner cap 4 and move it downward. In this state, the outer protrusion 18 on the outer wall of the lifting seat 9 slides along the stopper groove 19 on the inner wall of the inner cap 4 to prevent the rotation of the lifting seat 9. At the same time, the inner protrusion 10 on the inner wall of the lifting seat 9 presses the screw groove of the screw end 7 to rotate the shank 5. The shank 5 drives the stirring ring 15 in the bottle body 1 through the rib 13 to rotate, so that the cosmetic paste can be stirred. When the finger is released, the large spring 8 and the small spring 11 can return the lifting seat 9 and the button 12 by their elasticity. At the same time of returning, the stirring ring 15 rotates reversely to further stir the cosmetic paste. By reciprocating like this, a uniform stirring operation can be completed. After uniformly stirring, rotate the outer cap 3, and the outer cap 3 can remove the inner cap 4 from the bottle body 1, as shown in Figure 2, which facilitates cosmetic application.

[0026] The above description is only a more preferred specific embodiment of the present invention, and the protection scope of the present invention is not limited thereto. The above replacement may be a replacement of some structures, devices, or method steps, or may be a complete technical solution. Those made by equivalent replacement or modification based on the technical solution of the present invention and its inventive concept are all included within the protection scope of the present invention.
