ABSTRACT:
A plastic venting closure comprising a base wall, a peripheral skirt having internal threads adapted to engage the threads of a container and wherein the threads are interrupted at circumferentially spaced points to define axial venting passages for dissipating pressure of the contents as the closure is unthreaded from a container. At least some of the passages have an integral rib thereon spaced from the threads and extending axially. The radial thickness of each rib is less than that of the threads and preferably is arcuate in a radial direction and arcuate in a axial direction and preferably has an axial length greater than a transverse width such that it may span and engage several threads at the same time. The closure can be used with a glass container having a continuous thread and a plastic container having continuous thread or an interrupted thread. By having each rib arcuate in an axial direction it may engage a plurality of threads at different radial points on the rib thereby minimizing application and removal torque while centering the container relative to the closure.
