Abstract

See full text

An airtight lipstick, including an outer cover, an inner cover, a central core and a base; the inner cover is fixedly arranged within the outer cover; the base is internally provided with a cavity; the central core is arranged within the cavity; the central core is adapted to accommodate a lipstick mass; a bottom part of the outer cover removably snaps onto the base; a lower part of the inner cover is in an interference fit with an upper part of an inner wall of the cavity to achieve sealing effect. A stable structure is thus provided that only requires the inner cover to produce a smaller amount of elastic deformation to provide the lipstick container with airtightness, and is not easy to cause air leakage of the lipstick container due to misalignment, and hence more durable.
