Abstract
A screw-type closure molded of resilient plastic is provided with an internal thread having a smaller axial pitch spacing than the mating external thread of the container with which it is used, the difference between the two threads being designed to compensate for a number of variables affecting sidewall characteristics around the circumference of the closure, in order to secure more uniform application of sealing pressure and other advantages.
