摘要： A cosmetic container is provided. A housing (1) includes an upper lid (11) and a lower lid (12), where one side of the upper lid (11) and one side of the lower lid (12) are hinged to each other, the other side of the upper lid (11) and the other side of the lower lid (12) each are an open side, and the open side is configured to be locked and unlocked. The cosmetic container includes a powder tray (2), an inner lid (3), and a button assembly (4). When a button (43) is pressed, the other end of the button (43) stretches into a space under an oblique protrusion (26) of the powder tray (2) to lift the powder tray (2). The lifted powder tray (2) is close to the inner lid (3) and compresses a pump spring (25). A pump seat (27) is close to a pump pressure rod (32). An air pressure in the pump seat (27) is increased, such that a pump piston (34) is lifted to expose a powder inlet (331). In this process, a negative pressure is generated to suck out cosmetic powder (5) from an annular chamber (21). When the button (43) is released, the powder tray (2) is lowered and restored to seal the powder inlet (331). A liner formed by the powder tray (2) and the inner lid (3) is replaceable. The cosmetic is usually sealed and stored in the powder tray (2). In response to use, the button (43) is pressed and the cosmetic powder (5) is taken out. The present disclosure can reduce contamination of the cosmetic powder (5) when used, and can take out a required amount of the cosmetic powder to prevent waste.

摘要： The utility model provides an airtight structure of an airtight powder case, including a powder tray and an inner lid, where the inner lid is hinged to one side of the powder tray through a rotating shaft; the inner lid is configured to open and close the powder tray; an aperture of the powder tray is provided with a seal ring; the seal ring includes a first seal ring and a second seal ring; a lower side of the second seal ring is located at the aperture of the powder tray; a lower side of the first seal ring is connected to an upper side of the second seal ring (a die may be used for integral injection molding); the second seal ring is hard, while the first seal ring is soft; an upper side of the first seal ring is shaped as a downward flanging, and the flanging forms a top; and a bottom of the inner lid is configured to abut against the top of the flanging. The bottom of the inner lid squeezes the top of the flanging, such that the flanging of the first seal ring further deforms to effectively enhance airtightness. The utility model achieves desirable airtightness, can protect a cosmetic in the powder case from moisture, and can prolong the service life of the cosmetic.
