Detailed description of implementation methods

[0054] Embodiments of the present invention will be described below clearly and completely in conjunction with the embodiments of the present invention. It is evident that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in this field without creative effort fall within the scope of protection of the present invention.

[0055] It should be noted that the terms "first," "second," etc., in the following description, claims, and figures of the present invention are used to distinguish similar objects, and not to describe a specific order or sequence. It should be understood that these objects may be interchanged under appropriate circumstances to allow the implementation of the embodiments of the present invention described herein in an order other than that illustrated or described herein. Furthermore, the terms "include" and "have," as well as all their variants, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or device comprising a series of steps or units need not necessarily be limited to those clearly listed, but may include other steps or units that are not clearly listed or that are inherent in such processes, methods, products, or devices.

[0056] To facilitate description, terms of relative spatial orientation may be used here, such as "on," "above," "on the upper surface," "superior," etc., to describe the spatial position relationship of a device or feature with respect to other devices or features as illustrated in the figures. It should be understood that the terms of relative spatial orientation 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 inverted, the device described as being "on other devices or structures" or "above other devices or structures" will then be oriented "under other devices or structures" or "below other devices or structures." Thus, the exemplary term "above" can encompass both the "above" and "below" orientations.The device can also be oriented differently (rotated by 90 degrees or in other orientations) and the relative spatial descriptions used here must be interpreted accordingly.

[0057] Embodiment 1: As illustrated in Figures 1-9, a cosmetic mixing container comprises a lid assembly 10, a bottle assembly 20, an applicator assembly 30, and a mixing element. The applicator assembly 30 is installed inside the lid assembly 10. The lid assembly 10 can be closed onto the bottle assembly 20. The bottle assembly 20 has a Receiving cavity 23 to hold the cosmetic product; the mixing element is placed in receiving cavity 23. The mixing element can move along the axis of the bottle assembly 20 to mix the cosmetic product within receiving cavity 23. As illustrated in [Fig. 1], the distance between the outer wall of the mixing element and the inner wall of the bottle assembly 20 is L1, the width of receiving cavity 23 is L2, L1 < 0.1 * L2. Optionally, L1 < 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 length of the side 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 element within the cosmetic product in the bottle assembly, and the width of the mixing element is practically equal to the width of the receiving cavity in the bottle assembly. When the user shakes the cosmetic container, the mixing element can move axially within the bottle assembly, while uniformly mixing the cosmetic product. It will not get stuck between the brush handle and the bottle assembly due to insufficient volume, thus improving the mixing effect of the cosmetic product, user satisfaction, the makeup effect, and the effectiveness of the makeup application.

[0060] Optionally, the outer wall of the mixing element is in contact with the inner wall of the bottle assembly 20. Thus, when the cosmetic container is shaken and the mixing element moves along the axis of the bottle assembly 20, the mixing element 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 includes a hollow annular structure inside and is made of metal. The cosmetic product can circulate inside the mixing element, and the application assembly 30 can It can also be inserted inside the mixing element, so it will not affect the normal use of the cosmetic product; the use of metallic materials such as stainless steel, copper, aluminum, etc. to manufacture the mixing element will not affect the quality of the cosmetic product, will offer a good mixing effect and will not be easily damaged.

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

[0063] As illustrated in Figures 7-9, the elastic element comprises a first wave-shaped spring 40, the first spring 40 forming a closed annular structure. In this embodiment, a first elastic and wave-shaped spring 40 is used as a mixing element. Since the diameter of the first spring 40 is practically 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 deform elastically in several directions, thus achieving thorough mixing of the cosmetic product within the bottle assembly, making the cosmetic product uniform before use and improving the makeup effect. Alternatively, the first spring 40 is a circular ring, the diameter of the first spring 40 being greater than its height, 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 wavy structure.

[0065] As illustrated in Figures 1, 2, and 5, the bottle assembly 20 comprises a bottle body 21 and an intermediate ring 22 fixed to the opening of the bottle body 21. The bottle body 21 has a bottle base 24, and the interior of the bottle body 21 forms a receiving cavity 23. The application assembly 30 comprises a brush rod 31 and a brush head 32 fixed to the end of the brush rod 31. The end of the brush rod 31 is fixed to the inside 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 onto the bottle assembly 20, the brush rod 31 is fixed to the intermediate ring 22 by a thread, an internal plug 33 is disposed at the opening of the intermediate ring 22, the inner cap 33 serves to seal the intermediate ring 22, and during makeup, the inner cap 33 also serves to wipe excess product on the brush stem 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 move the mixing element up and down in the bottle body 21 to mix the cosmetic product. Then, the user twists the lid assembly 10 to separate it from the bottle assembly 20, and finally uses the brush head 32 to apply the cosmetic product to the makeup area. This cosmetic container is particularly suitable for cosmetic products that require mixing.

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

[0068] As illustrated in [Fig. 15], the height of the second spring 50 is H1, the height of the bottle assembly is H2, H1 > 0.7 * H2. The height of the second spring 50 refers to the height of the second spring in its 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 extends to mix the cosmetic product in the container. Optionally, as illustrated 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 enhance the mixing effect of the container.

[0069] Embodiment 3: As illustrated in Figures 19-27, in this embodiment, the elastic element comprises a third spring 60, the third spring 60 being spirally wound around 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 its diameter, i.e., 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 as the third spring 60 spirals around the circumference, it has a strong elastic deformation capacity, which promotes the mixing of the cosmetic product through its own deformation, ensuring thorough 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 includes a counterweight 70, the The counterweight 70 is an annular metal element. The counterweight 70 can be located on the side of the elastic element closest to the bottle assembly 20, or on the side of the elastic element furthest from the bottle assembly 20. Optionally, as illustrated in [Fig. 28], the counterweight 70 is located on the side of the elastic element furthest from the bottom of the bottle 24 of the bottle assembly 20. By using the elastic element and the counterweight as a mixing element, when the user shakes the cosmetic container, the elastic element and the counterweight move along the axis of the bottle assembly 20, and the elastic element and the counterweight can collide with each other, which improves the mixing effect of the cosmetic product compared to using a single elastic element as a mixing element.

[0071] In this embodiment, as illustrated in Figures 28 and 29, the mixing element 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 bottom of the bottle of the bottle assembly 20, i.e. that 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, thus improving the mixing effect of the cosmetic product. Since the first spring 40 has a corrugated structure, the contact between the counterweight 70 and the first spring 40 is made through spaced points rather than through 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 element onto the bottle base 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 base 24 of the bottle assembly 20 is at least one of the following shapes: square, elliptical, and circular. Here, the square shape can be a square, a rectangle, or another polygon. The elastic element and the counterweight 70 can be designed with different shapes according to actual requirements, thus adapting to various shapes of cosmetic containers. Optionally, the elastic element and the counterweight have the same orthogonal projection shape onto the bottle base 24 as the brush handle.

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

[0074] It should be noted that for ordinary people in the field, 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 patent protection for the present invention must be determined by the attached claims.
