Abstract
A screw-type linerless closure molded of resilient plastic is provided with a novel combination of sealing elements for accommodating storage overloads, large container tolerances and variable surface textures, to secure reliable sealing over a wide range of conditions. Operation of the principal sealing ridge is assisted by an adjacent pressure-relief groove, or grooves, and by separate overload-resisting elements. A supplementary sealing flange is also provided to accommodate irregularities of the mating surface of the container.
