[0016] The technical aspects of the embodiments of the present application will be clearly and completely described below in connection with the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by a person skilled in the art without performing creative labors belong to the scope of protection of the present application.

[0017] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the drawings below are intended to distinguish between similar objects without necessarily being used to describe a particular order or priority. It should be understood that the objects used in this manner may be interchanged where appropriate, such that the embodiments of this application described herein may, for example, be performed in an order other than that shown or described herein. Furthermore, the terms "comprise" and "have" and all variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units explicitly listed, and may include steps or units that are not explicitly listed, or other steps or units inherent to the process, method, product, or apparatus.

[0018] For ease of explanation, spatially relative terms such as "on," "above," "on top of," "on top of," and "on top of" are used herein to describe the spatial location of one device or feature relative to another device or feature as shown in the figures. It is understood that the spatially relative terms are intended to include different orientations in use or operation of the device other than the orientation described in the figures. For example, if a device in the drawings is turned upside down, a device described as "on top of other devices or structures" or "on top of other devices or structures" would later be positioned as "below other devices or structures" or "under other devices or structures." Thus, the exemplary term "above" may include two orientations: "on top of" and "below." The device may be positioned in other different ways (rotated 90 degrees or in other orientations) and appropriately accounted for in the spatially relative descriptions used herein.

[0019] As shown in Figs. 1 to 12, the airtight powder dispersion container includes an outer cover 10, an inner cover 20, an inner screen 30, and a base 40. The inner screen 30 is airtightly attached to the open end of the base 40, and the inner screen 30 is located between the inner cover 20 and the base 40. The inner cover 20 and the inner screen 30 are hinged by a hinge unit. The hinge unit has elasticity and can move the inner cover 20 toward the inner screen 30 when a force is applied. When the outer cover 10 covers the base 40, the outer cover 10 presses the inner cover 20 to airtightly bond the inner cover 20 to the inner screen 30. In the present application, the outer cover 10 and the inner cover 20 are two independent members, a puff can be placed in the inner cover 20, the base 40 is used to store cosmetics, and the inner cover 20 is placed in the inner screen 30. And the connection between the inner cover and the inner screen is an elastic hinge connection, so that the inner cover has a certain downward movement space. The connection part of the inner cover and the inner screen provides support to the inner cover part and enhances the stability of the inner cover. When the outer cover 10 is fastened to the base 40, the inner cover 20 is pressed toward the inner screen 30 under the action of the outer cover 10, and the contact surface between the inner cover 20 and the inner screen 30 is tightly attached with sufficient pressing force, so that the airtightness of the inner screen can be guaranteed, and the volatile solvent in the cosmetic in the base can be effectively prevented from volatilizing, and at the same time, the powder material can be prevented from scattering, and the service life of the cosmetic can be extended. When using, the outer cover is opened, the puff is taken out, and the inner cover 20 is rotated around the hinge connection part between the inner cover and the inner screen at a certain angle, so that the inner cover 20 can be opened, and the cosmetic in the base can be applied with the puff to complete the makeup process. Therefore, since the inner cover and the inner screen are connected by a hinge connection, there is no need to remove the inner cover when using the vehicle, and it is possible to prevent the inner cover from becoming soiled.Moreover, when not in use, the puff can be placed on the inner cover without touching the cosmetic, thereby preventing the cosmetic from excessively wetting the puff.

[0020] As shown in FIG. 3, the inner cover 20 is provided with a hinge shaft 21, the inner screen 30 is provided with an upper opening end and a lower opening end, and the lower opening end is provided with a passage for passing materials, the upper opening end extends upward to form a lug 31, the lug 31 is provided with a hinge hole 32 and an opening that communicate with each other, the hinge shaft 21 slides into the hinge hole 32 through the opening to hinge-connect the inner cover 20 to the inner screen 30, and the lug 31 is further provided with an elastic member for supporting the hinge shaft 21. The hinge unit includes the hinge shaft 21, the lug 31, and an elastic member. The inner screen is an annular structure including an upper opening end and a lower opening end. The cosmetics in the base 40 are discharged through the passage on the inner screen and used by the user. The hinge shaft 21 on the inner cover is engaged into the hinge hole 32 from the opening of the lug 31. The elastic member supports the hinge shaft 21. The elasticity of the elastic member is utilized to ensure the opening and closing function of the hinge unit, and ensure that the inner cover has a certain downward movement space. The elastic member may be a part of the lug 31, i.e., the lug and the elastic member are integrated. Or, the elastic member and the lug 31 are two independent members. When the outer cover presses the inner cover, the inner cover presses the elastic member and moves downward, so that the inner cover and the inner screen are closely attached to each other to form a sealing effect. The material of the inner screen is PP (Polypropylene) or PCTA (copolymer polyester).

[0021] In Example 1, as shown in Fig. 4, the hinge hole 32 and the opening are located on the outside or inside of the upper opening end, the opening is located above or below the hinge hole 32, and when the hinge shaft 21 is attached to the hinge hole, the elastic member is located below the hinge shaft 21. The hinge hole 32 and the opening are located on the outside of the upper opening end, and the opening is located below the hinge hole, and the hinge shaft 21 is attached to the hinge hole 32 by pressing the elastic member from the lower opening on the outside of the inner screen. In Example 2, as shown in Fig. 5, the hinge hole 32 and the opening are located on the inside of the upper opening end, and the opening is located below the hinge hole, and the hinge shaft 21 is attached to the hinge hole 32 by pressing the elastic member from the lower opening on the inside of the inner screen. In the third embodiment, as shown in FIG. 6, the hinge hole 32 and the opening are located outside the upper opening end, and the opening is located above the hinge hole, and the hinge shaft 21 is mounted in the hinge hole 32 from the upper opening on the upper side of the inner screen.

[0022] In Examples 1 to 3, the elastic member is an elastic claw 33 integrally formed with the lug 31, and the elastic claw 33 is disposed at an inclination in the opening of the lug 31 or disposed in the hinge hole 32. The elastic member is an elastic claw 33 in all cases. In Examples 1 and 2, as shown in Figs. 4 and 5, the opening is located below the hinge hole 32, the lug is provided with two elastic claws 33 arranged on the left and right, an opening is formed between the two elastic claws 33, and both of the two elastic claws are disposed at an inclination to the horizontal plane, so that the hinge shaft 21 can easily be inserted into the hinge hole 32 through the opening along the elastic claws. In Example 3, as shown in Fig. 6, the opening is located above the hinge hole 32, and the lug is provided with two elastic claws 33 arranged vertically, the upper elastic claw is located at the opening, and the lower elastic claw is located in the hinge hole, and similarly the elastic claws are disposed at an inclination to the horizontal plane. When the hinge shaft 21 slides along the upper elastic claw through the opening into the hinge hole 32, the hinge shaft 21 is supported by the lower elastic claw 33. Since the elastic claw is arranged at an angle and has elasticity, when the inner cover 20 receives a downward pressing force from the outer cover 10, the hinge shaft 21 on the inner cover 20 presses down on the elastic claw and moves downward as a whole, causing the contact surfaces of the inner cover 20 and the inner screen 30 to tightly contact each other.

[0023] The elastic member is a spring 34 or a soft rubber member 35, and the spring or the soft rubber member is disposed in the lug 31. In the fourth embodiment, as shown in FIG. 7, the elastic member is a spring 34, and the spring is disposed in the hinge hole 32 of the lug, and the spring is located below the hinge shaft. In the fifth embodiment, as shown in FIG. 8, the elastic member is a soft rubber member 35, and the soft rubber member 35 is disposed in the hinge hole 32 of the lug, and the soft rubber member 35 is located below the hinge shaft. In the fourth and fifth embodiments, the opening is located above the hinge hole 32. Similarly, when the inner cover 20 receives a downward pressing force from the outer cover 10, the hinge shaft 21 on the inner cover presses the spring 34 or the soft rubber member 35 and moves downward as a whole, causing the contact surfaces of the inner cover 20 and the inner screen 30 to come into close contact with each other.

[0024] As shown in FIG. 3, the outer diameter of the inner screen 30 is larger than the inner diameter of the base 40, and the upper open end of the inner screen 30 forms a round convex ring 36, which is tightly fitted into the open end of the base 40, and a round soft rubber tape 60 is provided between the inner screen 30 and the base 40. Since the outer diameter of the inner screen is slightly larger than the inner diameter of the base, when the inner screen is attached to the base, the inner screen and the base are tightly fitted together, ensuring airtightness between them. The soft rubber tape provided at the contact portion between the inner screen and the base also provides an airtight effect. The material of the soft rubber tape 60 is TPEE (thermoplastic polyester elastomer), and the hardness of the soft rubber tape is smaller than that of the inner screen and the base.

[0025] The soft rubber tape 60 is provided between the upper wall of the opening end of the base and the lower wall of the convex ring 36, or the soft rubber tape 60 is provided between the inner wall of the opening end of the base and the outer wall of the inner screen 30. Alternatively, the soft rubber tape 60 and the base 40 are an integrally molded product, and the soft rubber tape 60 and the base 40 are molded by two-color molding.
