CONTAINER AND LID OF MOLDED PLASTIC MATERIAL Abstract The fastener structure connects two peripherally interengaging, molded plastic members, the fastener structure consisting of two identical complementary, continuous, endless peripheral series of fastener elements. This structure as shown secures a lid to a can, the series of elements on the lid interengaging with the series on the wall of the can, the spaces between elements in each series being substantially similar to the elements, with each element narrower at its base than at the top so that the space between the bases of adjoining elements is wider to receive a com- plementary element. The two series are interengaged by pressing the two series together as the lid is inserted in the end of the can, the flexibility and resilience of the material allowing the two endless series to interengage. One of the wall structures is inclined so that the members are in wedging contact to form sealing surfaces. Each series of elements is fixed on the side of a wall, so that when the two walls are moved in the direc- tion of their contacting surfaces, the two series of elements interengage to hold the two wall structures in contact. To hold the wall structures in tight, seal- ing contact, the elements are inclined transversely to the direction of inter engagement, so that the contact- ing surfaces are pressed together by engagement of the fastener elements.
