Abstract
A container for mascara or the like, including a substantially rigid hollow inner member with a large open end and a smaller closed end, and a surrounding flexible sleeve extending from the open end of the inner member beyond the closed end of the inner member to a closed and flattened extremity simulating the appearance of a tube of oil paint. A complete mascara package also includes a neck disposed at the end of the container and a cap mountable on the neck and bearing an applicator for insertion into the container through the neck. Methods for making the container include molding the hollow member and sleeve integrally of plastic, with the sleeve extremity initially open, and thereafter flattening and closing the sleeve extremity; and providing the hollow member and sleeve as separate elements, the sleeve being a flexible metal tube into which the hollow member is inserted.
