Description

Technical Field

[0001] This utility model relates to the field of cosmetic containers, specifically a cosmetic container. Background Technology

[0002] Cosmetic containers come in a wide variety of types, each with its own unique features. Plastic bottles are durable and environmentally friendly, with diverse molding processes, and are suitable for lotions and detergents. Glass bottles are elegant and practical, offering excellent light protection and freshness preservation, and are often used for high-end skincare products and perfumes. Tubes are lightweight, pressure-resistant, and have strong sealing properties, making them easy to carry and suitable for face creams, eye creams, etc. Vacuum bottles feature an aseptic design, providing excellent freshness preservation and completely isolating the product from air, making them suitable for high-end serums and lotions.

[0003] Existing cosmetic containers have a problem during use: specifically, for female users with long manicures, some cosmetic fragments remain on the inside of the long nails when using their fingers to apply cosmetics, resulting in waste and reducing the convenience of using the cosmetic container. Therefore, the inventor urgently needs to design a container structure that can reduce the amount of cosmetics contaminated by the user's manicure, thereby improving the convenience of using cosmetics. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a cosmetic container to solve the technical problem that long fingernails easily come into contact with the inside of the container when taking cosmetics, causing cosmetics to be contaminated and difficult to remove completely, which not only wastes the product but also affects the user experience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cosmetic container, including a container body, a cavity formed on the inner side of the container body, an adjustment mechanism provided on the inner side of the cavity for adjusting the height of the top of the cosmetic, the adjustment mechanism including a support frame, an adjustment screw threadedly connected to the support frame, a limit plate installed at the bottom end of the adjustment screw, and a sealing ring provided on the outer side of the limit plate.

[0006] By adopting the above technical solution, the adjustable mechanism enables dynamic control of the liquid level of cosmetics. Users can precisely adjust the top layer of cosmetics to the container opening by rotating the adjusting screw to drive the limiting plate to move vertically. This completely avoids the problem of residue caused by the traditional container requiring fingers to reach deep into the bottom to take the product, and provides great convenience, especially for users with long nails.

[0007] Furthermore, the sealing ring abuts against the inner wall of the cavity. The sealing ring is made of rubber and is used to fit and abut against the inner wall of the sealing cavity. The adjusting screw is made of plastic and can be cut to length using a cutting tool.

[0008] By adopting the above technical solution, the sealing ring can perfectly adapt to the container cavity with different inner diameters, and achieve gapless sealing through elastic deformation. Even after long-term and frequent lifting and lowering, it can still maintain stable sealing performance, which is particularly suitable for the universal needs of cosmetics of different specifications and reduces production costs.

[0009] Furthermore, a slot is provided on the inner side of the adjusting screw, which is the point where an external tool applies force to the adjusting screw.

[0010] By adopting the above technical solution, a slot is opened on the inner side of the adjusting screw as a standardized tool interface. Users can insert common tools such as screwdrivers to apply torque, which solves the problems of laborious operation and insufficient precision of traditional container adjusting mechanisms. It is especially suitable for users with weak hand strength or long nail polish.

[0011] Furthermore, the cavity is connected to the space below the limiting plate to balance the pressure between the space below the limiting plate and the cavity space.

[0012] By adopting the above technical solution, an internal pressure balance system for the container is constructed. When the adjusting screw rises, the empty slot channel allows air to enter from above to compensate for the pressure, effectively preventing the sealing ring adsorption phenomenon caused by negative pressure and ensuring smooth and unobstructed lifting operation.

[0013] Furthermore, a sealing cover is attached to the inner upper part of the container body, and an avoidance groove is formed at the center of the bottom surface of the sealing cover, which is a receiving groove for the top end of the adjusting screw.

[0014] By adopting the above technical solution, the clearance groove provides a complete accommodating space for the top of the adjusting screw, ensuring that the screw will not compress the paste in the closed state, while maintaining a planar seal between the cover plate and the container opening. This solves the sealing failure problem caused by protruding parts in traditional lifting mechanisms, giving the container excellent waterproof and dustproof capabilities.

[0015] Furthermore, a protrusion is provided on one side of the sealing cover plate, which is the point where the user applies force to the sealing cover plate, and a cover is threadedly installed on the upper outer side of the container body.

[0016] By adopting the above technical solution, a clear point of force is provided for the user. Compared with the traditional smooth cover, this raised structure can significantly increase the friction, making the opening and closing operation more effortless, especially suitable for users with wet hands or weak grip strength.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model, through an adjustment mechanism, allows users to drive the limiting plate to rise and fall vertically by rotating the adjustment screw, ensuring that the cosmetic liquid level is always maintained above the cavity. When taking the product, there is no need to insert fingers or nails into the bottom of the container to contact the deep cream, fundamentally avoiding the waste caused by cosmetic residue on the inside of the nail. At the same time, the sealing ring and the inner wall of the cavity, combined with the double locking structure of the sealing cover, not only prevent external air from entering and causing oxidation and deterioration, but also prevent leakage of the contents when the container is tilted, ensuring that the cosmetic is always in a sterile and sealed state. Through mechanical control, it achieves an organic combination of contactless use and long-term preservation, solving the operational pain points of users with long nails and improving the overall convenience of use and product safety of the container.

[0019] 2. This utility model adjusts the shearable shape of the screw, with the top of the screw gradually increasing as it is turned, allowing users to cut the protruding part as needed using a cutting tool. This enables the container to continuously adapt to cosmetics of different capacities. When the amount of cream decreases, the cut screw maintains a gap fit with the sealing cover to avoid operational interference. At the same time, this adjustable structure extends the service life of the container and helps improve the adaptability of the cosmetic container to different usage environments.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] In this embodiment:

[0027] A cosmetic container, such as Figures 1-4As shown, the container includes a main body 1, with a cavity 3 formed inside the main body 1. An adjustment mechanism 4 is provided inside the cavity 3 to adjust the height of the top layer of cosmetics. The adjustment mechanism 4 includes a support frame 401, with an adjustment screw 402 threadedly connected to the support frame 401. A limit plate 403 is installed at the bottom of the adjustment screw 402, and a sealing ring 404 is provided on the outside of the limit plate 403. The adjustable mechanism 4 enables dynamic control of the liquid level of the cosmetics. By rotating the adjustment screw 402, the user can drive the limit plate 403 to move vertically, which can precisely adjust the top layer of cosmetics to the opening of the container. This completely avoids the problem of residue caused by the need to reach deep into the bottom of the container to use the product, which is especially convenient for users with long nails. At the same time, the rubber sealing ring 404 on the outside of the limit plate 403 forms a full circumferential seal with the inner wall of the cavity 3, which can prevent leakage caused by bumps during transportation or use, and significantly improve the product's freshness and safety.

[0028] See Figure 1 , Figure 4 The sealing ring 404 abuts against the inner wall of the cavity 3. The sealing ring 404 is made of rubber and is used to fit and abut against the inner wall of the sealing cavity 3. The adjusting screw 402 is made of plastic and can be cut to length using a cutting tool. The sealing ring 404 can perfectly fit the container cavity 3 with different inner diameters and achieves a gapless seal through elastic deformation. It can maintain stable sealing performance even after long-term frequent lifting and lowering. It is particularly suitable for the universal needs of cosmetics of different specifications, reducing production costs. At the same time, the adjusting screw 402 is made of cutable plastic material, which allows users to flexibly adjust the screw length according to the cosmetic capacity. When the amount of cream in the container decreases, the excess screw part can be removed by cutting tool. This can maintain the closed state of the sealing cover 5 and the cover 2, and avoid the inconvenience caused by the screw being too long. It significantly improves the environmental adaptability and service life of the container.

[0029] See Figure 3 , Figure 4 The inner side of the adjusting screw 402 is provided with a slot 405. The slot 405 is the point where external tools apply force to the adjusting screw 402. The slot 405 inside the adjusting screw 402 serves as a standardized tool interface, allowing users to insert common tools such as screwdrivers to apply torque. This solves the problems of laborious operation and insufficient precision of traditional container adjusting mechanisms, making it especially suitable for users with weak hand strength or long nail polish. At the same time, the slot design concentrates the force point on the central axis of the screw, ensuring a smooth and unbiased lifting process and avoiding misalignment of the sealing ring 404 or scratches on the inner wall of the container due to uneven force, significantly improving the reliability and durability of the adjusting mechanism.

[0030] See Figure 3 , Figure 4The slot 405 is connected to the space below the limiting plate 403 to balance the pressure between the space below the limiting plate 403 and the cavity 3, thus constructing an internal pressure balance system for the container. When the adjusting screw 402 rises, the slot 405 channel allows air to enter from above to compensate for the pressure, effectively preventing the adsorption of the sealing ring 404 caused by negative pressure, ensuring smooth lifting and lowering operations. At the same time, the pressure balance mechanism avoids splashing or air bubbles caused by pressure difference during the lifting and lowering process of cosmetics, maintaining the integrity of the cream's shape and preventing accidental contamination during use, significantly improving the comfort and safety of the container.

[0031] See Figure 1 , Figure 2 , Figure 4 The inner side of the container body 1 is covered with a sealing cover plate 5. A relief groove 6 is formed at the center of the bottom surface of the sealing cover plate 5, which is a receiving groove for the top of the adjusting screw 402. The relief groove 6 provides a complete receiving space for the top of the adjusting screw 402, ensuring that the screw will not compress the paste in the closed state, while maintaining the planar seal between the cover plate and the container opening. This solves the sealing failure problem caused by the protruding parts of the traditional lifting mechanism, giving the container excellent waterproof and dustproof capabilities. At the same time, the precise size control of the relief groove 6 ensures that the adjusting screw 402 always maintains a clearance fit with the cover plate during the lifting process, which significantly improves the structural stability and operational convenience of the container.

[0032] See Figure 1 , Figure 2 , Figure 4 A protrusion 7 is provided on one side of the sealing cover 5, which is the point where the user applies force to the sealing cover 5. The cap 2 is threadedly installed on the upper outer side of the container body 1, providing the user with a clear point of force application. Compared with traditional smooth caps, this protruding structure can significantly increase friction, making opening and closing operations easier, especially suitable for users with wet hands or weak grip strength. At the same time, the container body 1 and the cap 2 are installed by thread, which not only ensures the reliability of the seal, but also enhances the sealing effect through the axial pressure generated during the screwing process, extending the shelf life of cosmetics and significantly improving the product's hygiene standards and user experience.

[0033] The implementation principle of this embodiment is as follows: A cavity 3 is provided inside the container body 1. The adjustment mechanism 4 installed in the cavity 3 consists of a support frame 401, an adjustment screw 402, a limiting plate 403, and a rubber sealing ring 404. The user rotates the adjustment screw 402 to drive the limiting plate 403 to move vertically up and down in the cavity 3. This, combined with the sealing ring 404 abutting against the inner wall of the cavity 3, dynamically controls the level of the cosmetic liquid. When it is needed, the sealing cover 5 provides operating space for the adjustment screw 402 through the clearance groove 6. The user applies torque by inserting a tool into the groove 405. The cosmetic can be pushed to the container opening, and the cosmetic is always kept above the limiting plate 403, avoiding direct contact between fingers or nails and deep cosmetics. This reduces residue and waste, and the double seal of the cover 2 and the sealing plate 5 ensures product hygiene. As the adjusting screw 402 is gradually turned, the length of the top of the adjusting screw 402 protruding from the container body 1 will gradually increase. Users can use a cutting tool to cut the protruding part of the adjusting screw 402, thereby further improving the applicability and ease of use of the adjusting mechanism 4.
