Embodiment 1: As shown in FIGS. 1-9, a convenient-to-stir cosmetic container includes lid assembly 10, bottle assembly 20, applicator assembly 30, and a stirrer. The applicator assembly 30 is provided in the lid assembly 10. The lid assembly 10 can cover the bottle assembly 20. The bottle assembly 20 is provided therein with accommodation cavity 23 for storing a cosmetic material. The stirrer is provided in the accommodation cavity 23. The stirrer can move along an axial direction of the bottle assembly 20, so as to stir the cosmetic material in the accommodation cavity 23. As shown in FIG. 1, a distance between an outer peripheral wall of the stirrer and an inner peripheral wall of the bottle assembly 20 is L1, and the accommodation cavity 23 has a width of L2, L1≤0.1*L2. Optionally, L1≤0.07*L2.

The width of the accommodation cavity 23 is a minimum size of the accommodation cavity along a radial direction of the bottle assembly 20. For example, in response to a circular radial section of the accommodation cavity 23 along the bottle assembly 20, the width of the accommodation cavity 23 is a diameter of the radial section. In response to a square radial section of the accommodation cavity 23 along the bottle assembly 20, the width of the accommodation cavity 23 is an edge of the radial section. In response to a rectangular radial section of the accommodation cavity 23 along the bottle assembly 20, the width of the accommodation cavity 23 is a width of the radial section. In response to an elliptical radial section of the accommodation cavity 23 along the bottle assembly 20, the width of the accommodation cavity 23 is a minor-axis length of the radial section, etc.

According to the present disclosure, the stirrer is provided in the cosmetic material of the bottle assembly, with a width basically the same as a width of the accommodation cavity in the bottle assembly. When the cosmetic container is shaken, the stirrer can move along the axial direction of the bottle assembly. While uniformly mixing the cosmetic material, the stirrer is not stuck between the brush rod and the bottle assembly for the small size, thereby improving the mixing effect of the cosmetic material, and improving the user satisfaction, makeup effect and makeup efficiency.

Optionally, the outer peripheral wall of the stirrer is attached to the inner peripheral wall of the bottle assembly 20. In this way, when the cosmetic container is shaken, and the stirrer moves along the axial direction of the bottle assembly 20, the stirrer can fully stir the cosmetic material in the bottle assembly 20 to uniformly mix the cosmetic material.

Optionally, a shape enclosed by the outer peripheral wall of the stirrer is the same as a shape enclosed by the inner peripheral wall of the bottle assembly 20. This can ensure that a periphery of the stirrer and a periphery of the bottle assembly 20 are attached completely, thereby further improving the mixing effect of the cosmetic material. Optionally, the stirrer includes a hollow annular structure. The stirrer is made of a metal material. The cosmetic material can flow in the stirrer. The applicator assembly 30 can also be inserted into the stirrer, without affecting normal use of the cosmetic material. The stirrer made of the metal material such as stainless steel, copper, and aluminum does not affect the quality of the cosmetic material, achieves good stirring effect, and is not prone to damage.

Optionally, the stirrer includes an elastic member made of a metal material. While moving along the axial direction of the bottle assembly, the elastic member further causes deformations in a multidirectional manner. This further improves the stirring effect, and mixes the cosmetic material more uniformly.

As shown in FIGS. 7-9, the elastic member includes first spring 40 that is wavy. The first spring 40 encloses a sealed annular structure. In the embodiment, the first spring 40 that is elastic and wavy is used as the stirrer. A diameter of the first spring 40 is basically the same as an inner diameter of the bottle assembly. When the cosmetic container is shaken, the first spring 40 moves along the axial direction of the bottle assembly, and the first spring 40 can cause elastic deformations in a multidirectional manner. This fully stirs the cosmetic material in the bottle assembly, uniformly mixes the cosmetic material before use, and improves the makeup effect. Optionally, the first spring 40 is a circular ring. The diameter of the first spring 40 is greater than a height of the first spring 40. That is, the first spring 40 is a flat structure.

The first spring 40 includes a plurality of waves, as shown in FIG. 1, FIG. 5 and FIG. 6. When the first spring 40 is provided in the bottle assembly 20, the waves extend along the axial direction of the bottle assembly 20. As shown in FIG. 7, the first spring 40 is axially provided with highest point 41 and lowest point 42 at intervals to form a wavy structure.

As shown in FIG. 1, FIG. 2 and FIG. 5, the bottle assembly 20 includes bottle body 21 and intermediate ring 22 fixedly provided at a neck of the bottle body 21. The bottle body 21 includes the bottle bottom 24. The accommodation cavity 23 is formed in the bottle body 21. The applicator assembly 30 includes brush rod 31 and brush head 32 fixedly provided at a tail of the brush rod 31. A head of the brush rod 31 is fixedly provided in the lid assembly 10. The distance between the outer peripheral wall of the stirrer and the inner peripheral wall of the bottle assembly 20 is a distance between an outer peripheral wall of the elastic member and an inner peripheral wall of the bottle body 21. When the lid assembly 10 covers the bottle assembly 20, the brush rod 31 is threadedly connected to the intermediate ring 22. Internal stopper 33 is provided at an opening of the intermediate ring 22. The internal stopper 33 is configured to seal the intermediate ring 22. In makeup, the internal stopper 33 is further configured to scrape an excessive material on the brush rod 31 and the brush head 32. The brush head includes a bottom head, a flocking, a bristle, etc.

Before use of the cosmetic container, the container is shaken, such that the stirrer moves up and down in the bottle body 21 to mix the cosmetic material. Then, the lid assembly 10 is rotated, such that the lid assembly 10 is separated from the bottle assembly 20. At last, the cosmetic material is applied to a makeup portion with the brush head 32. The cosmetic container is particularly suitable for the cosmetic material to be mixed.

Embodiment 2: As shown in FIGS. 9-18, in the embodiment, the elastic member includes second spring 50. The second spring 50 moves up spirally along the axial direction of the bottle assembly 20.

As shown in FIG. 15, the second spring 50 has a height of H1, and the bottle assembly has a height of H2, H1≥0.7*H2. The height of the second spring 50 refers to the height of the second spring in a natural state. Optionally, the height of the second spring 50 is greater than a width of the second spring 50. In the embodiment, the elongated second spring 50 is used as the stirrer. When the cosmetic container is shaken, the second spring 50 retracts and extends repeatedly to stir the cosmetic material in the container. Optionally, as shown in FIG. 18, the second spring 50 is a square structure in a top view. The square second spring 50 is provided in the square accommodation cavity 23 of the bottle assembly to improve the stirring effect in the container.

Embodiment 3: As shown in FIGS. 19-27, in the embodiment, the elastic member includes third spring 60. The third spring 60 extends spirally along a circumferential direction of the bottle assembly 20. The third spring 60 encloses a sealed annular structure. Optionally, a height of the third spring 60 is less than a diameter of the third spring 60. That is, the third spring 60 is a flat structure. When the cosmetic container is shaken, the third spring 60 moves along the axial direction of the bottle assembly. The third spring 60 extending spirally along the circumferential direction has a high elastic deformation capacity, and stirs the cosmetic material through own deformations. This mixes the cosmetic material fully and uniformly before use to ensure the final makeup effect.

Embodiment 4: As shown in FIGS. 28-36, in the embodiment, the stirrer further includes weight 70. The weight 70 is a metal member of an annular structure. The weight 70 may be located at a side of the elastic member close to the bottle assembly 20, and may also be located at a side of the elastic member away from the bottle assembly 20. Optionally, as shown in FIG. 28, the weight 70 is located at a side of the elastic member away from the bottle bottom 24 of the bottle assembly 20. The elastic member and the weight are used as the stirrer. When the cosmetic container is shaken, the elastic member and the weight move along the axial direction of the bottle assembly 20. Meanwhile, the elastic member and the weight can collide with each other, compared with a case where the elastic member is individually used as the stirrer, the mixing effect of the cosmetic material is better.

In the embodiment, as shown in FIG. 28 and FIG. 29, the stirrer includes the first spring 40 and the weight 70. The weight 70 is located at a side of the first spring 40 away from the bottle bottom of the bottle assembly 20. That is, the weight 70 is located on the first spring 40. When the cosmetic container is shaken, the first spring 40 and the weight 70 move along the axial direction of the bottle assembly 20. Meanwhile, the first spring 40 and the weight 70 can collide with each other to improve the mixing effect of the cosmetic material. The first spring 40 is the wavy structure. The weight 70 and the first spring 40 contact through spaced points and do not contact completely, so the weight and the first spring are not adhered together easily to affect the stirring effect of the stirrer.

Orthographic projection of the elastic member on the bottle bottom 24 of the bottle assembly 20 is at least one of a square, an ellipse, and a circle. Orthographic projection of the weight 70 on the bottle bottom 24 of the bottle assembly 20 is at least one of a square, an ellipse, and a circle. The square may be a quadrate, a rectangle or other polygons. The elastic member and the weight 70 may have different shapes according to an actual need, thereby adapting for various shapes of the cosmetic container. Optionally, orthographic projection of the elastic member on the bottle bottom 24 and orthographic projection of the weight on the bottle bottom 24 are the same.

In other embodiments, the stirrer includes the second spring 50 and the weight 70, or the stirrer includes the third spring 60 and the weight 70. The mounting manner and the working principle are the same as those in Embodiment 4, and are not repeated herein.

It should be noted that a person of ordinary skill in the art can further make various variations and improvements without departing from the conception of the present disclosure. These variations and improvements all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the appended claims.
