CIERRE HERMETICO SEPARABLE PARA TAPA.

摘要

A lid (14) is engaged to a container (12) by the formation of interlocking waves (70, 72) of lid material (48) and container material (54). The interlocking waves are geometrically aligned relative to the interior of the container so as to maximize the burst strength of the container, and also to minimize the force required to peel the lid from the container.
