Abstract
A container for a cosmetic preparation such as mascara, lip gloss, etc., including a tubular inner plastic container and an outer metal shell which substantially encloses, and is substantially immovably fixed to, the inner container. The metal shell can serve to inhibit escape of vapor from the cosmetic solvent through the container wall. For improved integrity of the container, the inner surface of the metal shell can be formed with a set of circumferentially spaced, axially extending ribs which bite into the plastic of the inner container, when the container is assembled by pushing the shell onto the inner container, to form grooves in which the ribs engage tightly. An aperture can be formed in the outer shell for displaying to the user the color of the contained cosmetic preparation.
