Airtight cosmetic compact

An airtight cosmetic compact comprising:

• a base assembly including a base part with an accommodating cavity and an inner tray having a reservoir for storing a cosmetic product;
• a cover assembly pivotally coupled to the base assembly, the cover assembly including an outer cover, an inner cover, and a gasket;
• wherein the inner cover of the cover assembly is pivotally connected with the base assembly, and the outer cover of the cover assembly is rotatably connected to the base assembly;
• wherein the outer cover has limited rotational movement in relation to the inner cover;
• wherein the gasket is coupled to an inner surface of the inner cover, and wherein an upper rim of the inner tray abuts the gasket to provide an airtight seal when the airtight cosmetic compact is in a closed and locked position;
• wherein the inner tray is accommodated at least partially within the base part, the inner tray is movable axially relative to the base part when the outer cover is twisted to open or close the airtight cosmetic compact;
• and
• wherein an elastic member is positioned between the inner tray and the base part to elastically bias the inner tray in an upward direction;
• wherein an inner surface of a sidewall of the outer cover includes two lugs that are diametrically opposite;
• wherein an outer surface of a sidewall of the inner tray includes camming ramps, each of the camming ramps has an inlet groove part, an inclined groove part and a locking protrusion formed near a lower end of the inclined groove part;
• wherein in the open position, the elastic member biases the inner tray to its maximum upward limit;
• wherein to close the airtight cosmetic compact, the outer cover is rotated around a central axis of the airtight cosmetic compact, causing the two lugs to enter the camming ramps via the inlet groove parts and which in turn push the inner tray slightly downward against the elastic member;
• wherein further rotation moves the two lugs along the inclined groove parts to push the inner tray upward so that the upper rim of the inner tray abuts the gasket;
• wherein when the two lugs reach lower ends of the camming ramps, the two lugs override the locking protrusions, locking the cover assembly and creating an airtight seal;
• and
• wherein to open the airtight cosmetic compact, the outer cover is rotated to move the two lugs along the inclined groove parts and out of the camming ramps, breaking the airtight seal between the inner tray and the gasket, and the cover assembly is pivoted open to allow access to a cosmetic product, when stored in the inner tray.
