Abstract
Abstract A container is disclosed which includes a receptacle, a cover, and a label. The receptacle and the cover each include longitudinally extending skirt portions of rectangular configuration which are telescopically connected. The skirt portions of the receptacle and the cover each include side portions and rounded corner portions. When the skirt portions are telescopically connected, confronting corner portions engage one another with an interference fit to prevent lateral movement of the cover relative to the receptacle and to provide frictional resistance to longitudinal movement of the cover relative to the receptacle, and confronting side portions are stressed to hold the confronting corner portions against one another. The sides of the inner one of the skirt portions are convexly curved when viewed from the interior of the container so that confronting sides of the container are spaced from one another and so that any deflection of the inner sides caused by such inner sides being stressed will be in a direction away from the outer sides. This prevents interfering engagement of the confronting sides when the cover is assembled onto the receptacle with an interference fit, and provides a container in which the strength of a thin paper label is sufficient to hold and seal the cover on the receptacle without gluing the juncture of the cover and the receptacle.
