Abstract
A container particularly well suited for maintaining an air-tight seal for protecting cosmetic compositions stored therein is provided. The container includes an openable top hinged to a container bottom, one of which includes a deformable flange. The flange is formed of a thin deformable material which is deflected towards the opposite member when the container top is closed. This compression of the dish flange effectively provides an air-tight seal when the container is held in a closed position.
