Detailed description of embodiments

[0054] The embodiments of the present invention will be described below clearly and completely in combination with the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the field without creative effort belong to the protective scope of the present invention.

[0055] It should be noted that the terms "first", "second", etc. in the description, claims and subsequent figures of the present invention are used to distinguish like subject matter, not to describe a specific order or sequence. It should be understood that these subject matter may be interchanged in appropriate circumstances to enable the embodiments of the present invention described herein to be carried out in an order other than that illustrated or described herein. In addition, the terms "comprise" and "have" and all variations thereof are intended to cover a non-exclusive inclusion, e.g., a process, method, system, product or device comprising a series of steps or units need not be limited to those clearly enumerated, but may include other steps or units not clearly enumerated or inherent in such processes, methods, products or devices.

[0056] For ease of description, relative spatial orientation terms may be used herein, such as "on," "above," "on the top surface," "upper," etc., to describe the spatial positional relationship of a device or feature relative to other devices or features as illustrated in the figures. It is to be understood that the relative spatial orientation terms are intended to encompass different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the figures is turned upside down, then the device described as being "on other devices or structures" or "above other devices or structures" will be oriented "under other devices or structures" or "below other devices or structures." Thus, the exemplary term "above" may encompass both the "above" and "below" orientations.The device may also be oriented differently (rotated 90 degrees or in other orientations) and the relative spatial descriptions used herein should be interpreted accordingly.

[0057] Embodiment 1: As illustrated in Figures 1-9, a cosmetic container facilitating mixing comprises a lid assembly 10, a bottle assembly 20, an application assembly 30 and a mixing member. The application assembly 30 is installed inside the lid assembly 10, the lid assembly 10 can be closed on the bottle assembly 20, the bottle assembly 20 has a receiving cavity 23 for containing the cosmetic product, the mixing element is placed in the receiving cavity 23, the mixing element can move along the axis of the bottle assembly 20 to mix the cosmetic product in the receiving cavity 23. As shown in [Fig.l], the distance between the outer wall of the mixing element and the inner wall of the bottle assembly 20 is Ll, ​​the width of the receiving cavity 23 is L2, Ll<0.l*L2. Optionally, Ll<0.07*L2.

[0058] The width of the receiving cavity 23 refers to the minimum dimension of the receiving cavity in the radial direction of the bottle assembly 20. For example, when the radial section of the receiving cavity 23 along the bottle assembly 20 is circular, the width of the receiving cavity 23 is the diameter of the radial section; when the radial section of the receiving cavity 23 along the bottle assembly 20 is square, the width of the receiving cavity 23 is the side length of the radial section; when the radial section of the receiving cavity 23 along the bottle assembly 20 is rectangular, the width of the receiving cavity 23 is the width of the radial section; when the radial section of the receiving cavity 23 along the bottle assembly 20 is elliptical, the width of the receiving cavity 23 is the length of the minor axis of the radial section; etc.

[0059] The present invention places a mixing member in the cosmetic of the bottle assembly, and the width of the mixing member is substantially equal to the width of the receiving cavity in the bottle assembly. When the user shakes the cosmetic container, the mixing member can move axially in the bottle assembly, while uniformly mixing the cosmetic, it will not get stuck between the brush rod and the bottle assembly due to too small a volume, thereby improving the mixing effect of the cosmetic, user satisfaction, makeup effect and makeup efficiency.

[0060] Optionally, the outer wall of the mixing member is in contact with the inner wall of the bottle assembly 20. Thus, when the cosmetic container is shaken and the mixing member moves along the axis of the bottle assembly 20, the mixing member can completely mix the cosmetic product inside the bottle assembly 20, making the cosmetic product uniformly mixed.

[0061] Optionally, the shape defined by the outer wall of the mixing element is identical to the shape defined by the inner wall of the bottle assembly 20. This ensures that the mixing element is in full contact with all four sides of the bottle assembly 20, further improving the mixing effect of the cosmetic product. Optionally, the mixing element comprises a hollow annular structure inside, the mixing element is made of metal. The cosmetic product can circulate inside the mixing element, and the application assembly 30 can also be inserted inside the mixing element, so it will not affect the normal use of the cosmetic product; the use of metal materials such as stainless steel, copper, aluminum, etc. to manufacture the mixing element will not affect the quality of the cosmetic product, provide good mixing effect and will not be easily damaged.

[0062] Optionally, the mixing element comprises a metal elastic element. The elastic element, while moving axially in the bottle assembly, will also deform in multiple directions, further improving the mixing effect and making the cosmetic product more uniformly mixed.

[0063] As illustrated in Figures 7-9, the elastic member comprises a wave-shaped first spring 40, the first spring 40 forming a closed annular structure. In this embodiment, an elastic and wave-shaped first spring 40 is used as a mixing member. Since the diameter of the first spring 40 is substantially equal to the inner diameter of the bottle assembly, when the user shakes the cosmetic container, the first spring 40 moves along the axis of the bottle assembly, and the first spring 40 can elastically deform in multiple directions, thereby achieving thorough mixing of the cosmetic in the bottle assembly, making the cosmetic uniform before use, and improving the makeup effect. Optionally, the first spring 40 is a circular ring, the diameter of the first spring 40 is greater than the height of the first spring 40, i.e., the first spring 40 has a flattened structure.

[0064] The first spring 40 comprises several undulations, as illustrated in Figures 1, 5 and 6, when the first spring 40 is placed in the bottle assembly 20, the undulations extend along the axis of the bottle assembly 20. As illustrated in [Fig.7], the first spring 40 has highest points 41 and lowest points 42 arranged alternately along the axis to form a wave-like structure.

[0065] As illustrated in Figures 1, 2 and 5, the bottle assembly 20 comprises a bottle body 21 and an intermediate ring 22 attached to the opening of the bottle body 21, the bottle body 21 having a bottle bottom 24, the interior of the bottle body 21 forming a receiving cavity 23, the application assembly 30 comprising a brush rod 31 and a brush head 32 attached to the end of the brush rod 31, the end of the brush rod 31 being attached to the interior of the lid assembly 10. The distance between the outer wall of the mixing element and the inner wall of the bottle assembly 20 is the distance between the outer wall of the elastic element and the inner wall of the bottle body 21. When the lid assembly 10 is closed on the bottle assembly 20, the brush rod 31 is attached to the intermediate ring 22 by a thread, an inner plug 33 is arranged at the opening of the intermediate ring 22, the inner cap 33 serves to seal the intermediate ring 22, and when applying makeup, the inner cap 33 also serves to wipe off excess product on the brush rod 31 and the brush head 32, the brush head includes a cotton head, a flocked head, brush bristles, etc.

[0066] Before using this cosmetic container, the user shakes the container to make the mixing element in the bottle body 21 move up and down to mix the cosmetic, then the user rotates the cover assembly 10 to separate the cover assembly 10 from the bottle assembly 20, and finally uses the brush head 32 to apply the cosmetic to the makeup area. This cosmetic container is particularly suitable for cosmetics requiring mixing.

[0067] Embodiment 2: As illustrated in Figures 9-18, in this embodiment, the elastic member comprises a second spring 50, the second spring 50 spirally coiling along the axis of the bottle assembly 20.

[0068] As shown in [Fig. 15], the height of the second spring 50 is Hl, the height of the bottle assembly is H2, Hl>0.7*H2. The height of the second spring 50 refers to the height of the second spring in the natural state, optionally, the height of the second spring 50 is greater than the width of the second spring 50. In this embodiment, an elongated second spring 50 is used as a mixing element, when the user shakes the cosmetic container, the second spring 50 repeatedly contracts and expands to mix the cosmetic in the container. Optionally, as shown in [Fig. 18], the plan view of the second spring 50 is square, the square second spring 50 is placed in the square receiving cavity 23 of the bottle assembly to improve the mixing effect of the container.

[0069] Embodiment 3: As illustrated in Figures 19-27, in this embodiment, the elastic member comprises a third spring 60, the third spring 60 spirally winding along the circumference of the bottle assembly 20, the third spring 60 forming a closed annular structure. Optionally, the height of the third spring 60 is less than the diameter of the third spring 60, that is, the third spring 60 has a flattened structure. When the user shakes the cosmetic container, the third spring 60 moves along the axis of the bottle assembly, and since the third spring 60 spirally winds along the circumference, it has a strong elastic deformation capacity, which promotes the mixing of the cosmetic product by its own deformation, ensuring complete mixing of the cosmetic product before use and guaranteeing the final makeup effect.

[0070] Embodiment 4: As illustrated in Figures 28-36, in this embodiment, the mixing element also comprises a counterweight 70, the counterweight 70 is an annular metal member, the counterweight 70 may be located on the side of the elastic member close to the bottle assembly 20, or on the side of the elastic member far from the bottle assembly 20. Optionally, as shown in [Fig.28], the counterweight 70 is located on the side of the elastic member far from the bottle bottom 24 of the bottle assembly 20. By using the elastic member and the counterweight as the mixing member, when the user shakes the cosmetic container, the elastic member and the counterweight move along the axis of the bottle assembly 20, and the elastic member and the counterweight can collide with each other, which improves the mixing effect of the cosmetic product compared with using a single elastic member as the mixing member.

[0071] In this embodiment, as illustrated in Figures 28 and 29, the mixing member comprises a first spring 40 and a counterweight 70, the counterweight 70 being located on the side of the first spring 40 away from the bottle bottom of the bottle assembly 20, i.e., the counterweight 70 is located above the first spring 40. When the user shakes the cosmetic container, the first spring 40 and the counterweight 70 move along the axis of the bottle assembly 20, and the first spring 40 and the counterweight 70 can collide with each other, thereby improving the mixing effect of the cosmetic product. Since the first spring 40 has a wave-like structure, the contact between the counterweight 70 and the first spring 40 is at spaced points rather than across the entire surface, which prevents them from sticking together and therefore does not affect the mixing effect of the mixing element.

[0072] The orthogonal projection of the elastic member onto the bottle bottom 24 of the bottle assembly 20 is at least one of the following shapes: square, elliptical, and circular, the orthogonal projection of the counterweight 70 onto the bottle bottom 24 of the bottle assembly 20 is at least one of the following shapes: square, elliptical, and circular. Here, the square shape may be a square, a rectangle, or another polygon. The elastic member and the counterweight 70 may be designed with different shapes according to actual needs, thus adapting to various shapes of cosmetic containers. Optionally, the elastic member and the counterweight have the same orthogonal projection shape onto the bottle bottom 24 of the brush rod.

[0073] In other embodiments, the mixing element may comprise a second spring 50 and a counterweight 70, or a third spring 60 and a counterweight 70, the installation method and operating principle being similar to embodiment 4, they will not be repeated here.

[0074] It should be noted that for ordinary persons in the art, without departing from the idea of ​​the present invention, it is still possible to make various modifications and improvements, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent of the present invention is to be determined by the appended claims.
