CONTAINER AND CLOSURE THEREFOR

摘要

A container with a closure retention groove is provided with a rigid stacking ring structure of reduced height, comprising a vertical wall section extending upwardly from the outer periphery of a horizontal lower stacking shoulder to the inner periphery of a horizontal annular rim. A compressional camming wall section extends inwardly and downwardly from the inner periphery of the lower stacking shoulder to the upper extent of the closure retention groove. A closure for the container can be formed so that the portion of the closure between the closure rim and the retention bead grips the portion of the container between the retention groove and the container rim, to secure the closure to the container.
