Abstract
A flexible tube and a container manufactured with a detachable cover that is reusable as a cap. The detachable cover includes a plastic top member and a skirt. The plastic top member has a neck and a cover. The neck is connected to the cover by a tearable ring-shaped part. The cover has a circular plate with an interlocking mechanism, for example, at least three lugs projecting radially from a periphery of the circular plate. The skirt has a common axis of symmetry with the cover and has an inner surface that follows the periphery of the circular plate. The skirt also has a receiving mechanism, for example, at least three cavities that are positioned to receive the at least three lugs such that the skirt becomes immobilized with respect to the plastic top member. The skirt encircles the outer surface of the neck. The skirt and the cover are configured to cap the flexible tube or container after tearing the tearable ring-shaped part.
