[0002] There are many cosmetic containers on the market, especially products like mascara, which usually contain highly viscous materials. Therefore, during use, these materials are very easy to adhere to the inner wall of the container, resulting in uneven distribution of materials, affecting the user experience and effect.

[0003] To solve this problem, a mixing element is usually designed inside a traditional cosmetic container so that it can move back and forth inside the container to scrape off the material adhering to the inner wall of the container, ensuring that the material in the container can be fully stirred and mixed evenly.

[0004] However, due to the large inner wall area of ​​the cosmetic container, the displacement of the mixing element inside the container is limited.

[0034] [Example 1]

[0035] like Figure 1-Figure 4 As shown, embodiment 1 discloses a mixing element 12 accommodated in a storage bottle 11, a through hole is provided on the side wall of the mixing element 12, the center of gravity of the mixing element 12 is offset from its own central axis, the mixing element 12 can rotate circumferentially along the central axis, and when the mixing element 12 rotates circumferentially, the materials pass through the through hole to achieve mixing. The mixing element 12 is used to be placed in the storage bottle 11. Since the radial dimension of the mixing element 12 is smaller than the inner diameter of the storage bottle 11, the mixing element 12 can move relative to the storage bottle 11 along the axial direction Z of the storage bottle 11, and rotate circumferentially around the axis of the storage bottle 11 of the mixing element 12. Here, the central axes of the mixing element 12 and the storage bottle 11 both refer to the axes in the vertical direction, and the axial direction Z of the mixing element 12 is parallel to the axial direction Z of the storage bottle 11. That is to say, the mixing element 12 is placed in the storage bottle 11. When the storage bottle 11 is subjected to external force, such as being shaken up and down, rotated or swung, the mixing element 12 inside the storage bottle 11 can move relative to the storage bottle 11 along the axial direction Z of the storage bottle 11, and can also rotate circumferentially around the central axis of the mixing element 12.

[0036] Therefore, in this embodiment, by utilizing the principle of the center of gravity offsetting its central axis, the rotational inertia of the mixing element 12 when placed inside the storage bottle 11 can be increased, so that the mixing element 12 can move along the axis direction Z of the storage bottle 11 and can also rotate circumferentially inside the storage bottle 11 to achieve the effect of scraping the materials and evenly mixing the materials. At the same time, the center of gravity offset of the mixing element 12 makes it form an unstable element in the storage bottle 11, so when the storage bottle 11 is shaken, the mixing element 12 will rotate circumferentially around its own central axis due to the center of gravity offset, thereby achieving the purpose of mixing the materials.

[0037] like Figure 1-Figure 4 As shown, the mixing element 12 is a square tube structure that is through from top to bottom. The mixing element 12 includes a first side wall 121 and a second side wall 122. The first side wall 121 extends along a first direction X, and the second side wall 122 extends along a second direction Y. The first direction X and the second direction Y are both perpendicular to the axial direction Z of the mixing element 12, that is, the first direction X and the second direction Y are both located in the radial direction of the storage bottle 11, and the first direction X and the second direction Y are perpendicular to each other. The thickness of the first side wall 121 is different from the thickness of the second side wall 122. The thickness refers to the length dimension of the side wall extending in the direction, that is, the length dimension of the first side wall 121 extending in the first direction X is different from the length dimension of the second side wall 122 extending in the second direction Y. In other embodiments, the mixing element 12 is a polygonal structure, and the mixing element 12 includes a plurality of side walls. Through holes may be asymmetrically arranged on the side walls, and the shapes of the through holes may be the same or different, so that the center of gravity of the mixing element 12 deviates from the center of gravity axis, thereby realizing that the mixing element 12 can rotate circumferentially in the storage bottle 11, thereby improving the material mixing effect.

[0038] Therefore, the use of the above-mentioned structural form will cause the mass distribution of the mixing element 12 to be uneven, thereby causing the mixing element 12 to form an element with an unstable center of gravity in the storage bottle 11, so that the mixing element 12 generates unbalanced centrifugal force during rotation, so that when the storage bottle 11 is shaken, the mixing element 12 inside it is more likely to rotate circumferentially around the axis of the storage bottle.

[0039] In this embodiment, the first direction X is the length direction of the mixing element 12 , and the second direction Y is the width direction of the mixing element 12 .

[0040] Furthermore, at least one pair of oppositely disposed side walls of the mixing element 12 is provided with through holes for material flow, and preferably, the through holes include a first through hole 1211 disposed on the first side wall 121, and the first through hole 1211 is in a continuous extending form along the axial direction Z of the mixing element 12. In addition, the through holes also include a second through hole disposed on the second side wall 122, and a plurality of second through holes are arranged along the axial direction Z of the mixing element 12.

[0041] Since the designs of the first through hole 1211 and the second through hole are different, the mass distribution of the first side wall 121 and the second side wall 122 will also be different, thereby resulting in uneven mass distribution of the mixing element 12 and further enhancing the circumferential rotation effect of the mixing element 12 .

[0042] Furthermore, the number of the first through holes 1211 is the same as or different from the number of the second through holes. In this embodiment, the first through holes 1211 and the second through holes are different in structure and number. Figure 1-Figure 4 As shown, a first through hole 1211 for material flow is provided on the first side wall 121 of the mixing element 12, and a clamping groove 1221 is provided on the second side wall 122 of the mixing element 12 to position the mixing element 12 during processing, thereby ensuring that the position of the mixing element 12 is accurate during processing, thereby improving processing accuracy and consistency. For details, see Figure 2 and Figure 4 The first through hole 1211 is a through hole that penetrates from front to back for material circulation. The clamping groove 1221 is a concave shape with one end closed and the other end open, that is, the side wall of the storage bottle 11 is concave in the radial direction toward the central axis of the storage bottle 11 to form the clamping groove 1221 for clamping by other components.

[0043] In other embodiments, the second through holes and the clamping grooves 1221 may be alternately arranged on the second side wall 122 to simultaneously achieve the functions of positioning the second side wall 122 and providing material flow.

[0044] like Figure 3 As shown, along the axial direction Z of the mixing element 12, the clamping grooves 1221 arranged on the second side wall 122 are staggered. Specifically, there is only one clamping groove 1221 in the radial direction of the storage bottle, and it will not be on the same plane with the clamping groove 1221 arranged on the other second side wall.

[0045] Furthermore, an angle is provided between the extension direction of the through hole and the axial direction Z of the mixing element 12. Specifically, the extension direction of the first through hole 1211 is the flow direction of the material in the first through hole 1211, that is, the front-to-back penetration direction of the first through hole 1211. The extension direction of the first through hole 1211 is located on a horizontal plane where the radial direction of the central axis of the storage bottle 11 is located. In this way, when the mixing element 12 moves in the storage bottle 11, a lateral force relative to the rotation of the storage bottle 11 can be generated, and such a setting can also reduce the resistance of the mixing element 12 to rotation in the storage bottle 11, so that the mixing element 12 can rotate more smoothly and improve its rotation efficiency.

[0046] Preferably, the angle between the extension direction of the first through hole 1211 and the axial direction Z of the mixing element 12 is α, where 0°<α≤90°. Because the size of the angle will affect the flow direction and speed of the material in the first through hole 1211, thereby affecting the fluid dynamics performance of the material circulation, therefore, in this embodiment, the angle between the extension direction of the first through hole 1211 and the axial direction Z of the mixing element 12 is limited to be greater than 0° and less than or equal to 90°. Therefore, by selecting a suitable angle, the flow characteristics of the material can be optimized, eddy currents and dead zones can be reduced, and the mixing efficiency of the material can be improved.

[0047] like Figure 1 and Figure 3 As shown, in this embodiment, the first through hole 1211 is an S-shaped structure extending along the axial direction Z of the mixing element 12. The design of the S-shaped through hole increases the channel area for material flow. Compared with straight holes, the S-shaped through hole provides more circulation space on the same cross section, allowing more materials to pass through. This arrangement enables the material to pass through the mixing element 12 more smoothly, reducing its circulation resistance in the containing bottle and improving the circulation efficiency of the material. At the same time, the S-shaped through hole can change the flow rate and flow direction of the material when it flows, which helps to optimize fluid dynamics, reduce eddy currents and dead corners, and improve the overall stirring effect.

[0048] Alternatively, in other embodiments, the through hole is a spiral structure surrounding the outer wall of the mixing element 12. The design of the spiral through hole creates an inclined surface in its tangential direction relative to the axial direction Z of the mixing element 12, and when material flows through the first through hole 1211, a lateral force can be generated to allow the mixing element 12 to rotate circumferentially, thereby further enhancing the effect of its circumferential rotation.

[0049] In this embodiment, along the length direction of the mixing element 12, the length of the S-shaped first through hole 1211 extending relative to the length of the mixing element 12 is in the range of 0.3L-0.75L; along the axial direction Z of the mixing element 12, the height of the first through hole 1211 extending relative to the height of the mixing element 12 is in the range of 0.5L-0.8L.

[0050] In other embodiments, the structural form of the first through hole 1211 is not limited to the above-mentioned S-shape and the above-mentioned size range, and other shapes and other proportion ranges can also be adopted. For example, a brand logo is engraved on the mixing element 12, etc. It can be specifically set as needed according to other factors such as the viscosity of the material and the flow requirements.

[0051] Furthermore, the first through hole 1211 is arranged on the first side wall 121 in a mirror-symmetrical manner that is flipped horizontally or vertically. Since the first through hole 1211 is asymmetrical on the first side wall 121, the mass distribution of the mixing element 12 is uneven, which can also further enhance the circumferential rotation effect of the mixing element 12.

[0052] In addition, chamfers 123 are provided between adjacent outer side walls of the mixing element 12 to achieve a smooth transition connection between adjacent side walls. The purpose of providing the chamfers 123 is to reduce the impact and friction on the inner wall surface of the storage bottle 11 when the mixing element 12 rotates circumferentially and moves axially, which can reduce damage to the inner wall surface of the storage bottle 11 and avoid damage to its own structure. Moreover, the chamfers 123 can adopt a rounded structure or an arc structure with a certain curvature, which is not limited and can be provided as required.

[0053] [Example 2]

[0054] like Figure 5-Figure 10 As shown, the present application discloses a material storage container 100, which includes the mixing element 12 described in Example 1, and a storage bottle 11, the storage bottle 11 is used to store materials, the mixing element 12 is arranged in the storage bottle 11, and can move relative to the storage bottle along the axial direction Z of the storage bottle 11, and the center of gravity of the mixing element 12 is offset from its own central axis, and the radial dimension of the mixing element 12 is smaller than the inner diameter of the storage bottle 11, so that a gap is generated between the mixing element 12 and the inner wall of the storage bottle 11, so that the mixing element 12 can rotate circumferentially relative to the storage bottle 11. Wherein, the materials include cosmetics and some paste or liquid makeup products, such as mascara, lip gloss and other products with a certain viscosity.

[0055] Therefore, in the present application, the principle of offsetting the center of gravity from its central axis is utilized to increase the rotational inertia of the mixing element 12 inside the storage bottle 11, and the radial dimension of the mixing element 12 is smaller than the inner diameter of the storage bottle 11, so that when the material storage container 100 is subjected to external force, the mixing element 12 inside the storage bottle 11 can move along the axial direction Z of the storage bottle 11, and can also rotate circumferentially inside the storage bottle 11, so as to achieve the effect of uniform mixing of the materials.

[0056] Preferably, along the axial direction Z of the storage bottle 11, the inner wall section of the storage bottle 11 is square, and the mixing element 12 is a square tube structure with a hollow interior. By designing the mixing element 12 as a square tube structure with a hollow interior, it is adapted to the shape of the inner wall of the storage bottle 11, so that the two are more closely fitted, so as to reduce or eliminate dead corners for scraping, prevent materials from accumulating on the inner wall of the storage bottle 11, and improve the uniformity of the materials. It is understandable that the overall structure of the storage bottle 11 can be square, round or other special-shaped structures.

[0057] Furthermore, the cross-sectional shape of the mixing element 12 is a square with right angles or a square with rounded corners, so that the mixing element 12 can fit the inner wall of the storage bottle 11, so that the gap between the two can be minimized when the mixing element 12 moves, thereby reducing or eliminating the scraping dead angle, which helps to ensure that the material can be effectively scraped from the inner wall and maintain uniform mixing. In this embodiment, the description of the gap is not specifically limited, because the gap here can not only realize the movement of the mixing element 12 in the storage bottle 11, but also meet the need of the mixing element 12 to scrape the material on the inner wall of the storage bottle 11, and at the same time, it can also meet the need that other additional components can be smoothly inserted into the interior of the mixing element 12 to achieve material dipping.

[0058] Among them, when a square mixing element 12 with a right-angled cross-section is selected, the outer wall of the mixing element 12 can contact every point of the inner wall of the storage bottle 11, especially at the right angles, so that the material can be effectively scraped off; when a square mixing element 12 with a rounded corner structure is selected, the damage that the mixing element 12 may cause to the inner wall during movement can be reduced, thereby ensuring the integrity of the storage bottle 11.

[0059] In other embodiments, the cross-sectional shape of the mixing element 12 is not limited to the above two forms, and can be specifically set as needed according to the structural form of the inner wall of the storage bottle 11 .

[0060] like Figure 5-Figure 10As shown, the material holding device 100 further includes a bottle cap 13, a connecting rod 14, an inner plug 15 and a clamping member 16, wherein the bottle cap 13 and the connecting rod 14 are movably connected, and the detachable connection between the two can be achieved by bonding, clamping, threaded connection and other connection forms. In this embodiment, a recessed groove for accommodating the connecting rod 14 is provided inside the bottle cap 13, so that one end of the connecting rod 14 can be embedded therein, and the other end of the connecting rod 14 is provided with a coating end 141, which is inserted into the storage bottle 11 and enters into the hollow structure of the mixing element 12 to achieve full contact with the material. The clamping member 16 is arranged at the outlet end 111 of the containing bottle 11, and the connection between the clamping member 16 and the containing bottle 11 is achieved by means of clamping and interference fit. The inner plug 15 is made of rubber and is located at one end of the clamping member 16 facing its opening 161. A part of the inner plug 15 is embedded in the inside of the clamping member 16, and the other part extends to the outside of the opening 161 and covers the opening 161 to scrape and filter the material at the smearing end 141 on the connecting rod 14.

[0061] The above description has fully disclosed the specific implementation methods of the present application. It should be pointed out that any changes made by technicians familiar with the field to the specific implementation methods of the present application do not deviate from the scope of the claims of the present application. Accordingly, the scope of the claims of the present application is not limited to the above specific implementation methods.
