Resealable Flexible Container Lid with Pivoting Portions

摘要

A closure is disclosed for a container. The container comprises a base and a peripheral wall. A rim forms an upper margin of the wall and surrounds an opening of the container. An external protrusion is formed integrally with and surrounds the rim. A portion of the closure is adapted to overlie the opening of the container. A skirt is formed integrally with the closure portion and is arranged to surround the rim when the closure is mounted to the container. The skirt comprises a first portion that is positionable adjacent to and to surround an external upper end of the rim. The skirt further comprises a second portion that is connected to the first portion at a connection and that extends downwardly therefrom to surround the rim below its upper end. The second portion also comprises an integrally formed first ledge located therewithin that is positionable to locate in interlocking engagement with the external protrusion. The connection has a width W sufficiently greater than its thickness so as to facilitate pivoting of the second portion with respect to the first portion to enable disengagement of the first ledge from the external protrusion. The second portion can also comprise a continuous and unbroken profile moving around the closure.
