Kindersicherer Schraubverschluss

摘要

A child resistant package which includes a container (20 or 20a) having an open end and single or multiple threads (22 or 78) on the external surface of the container adjacent the upper end A closure (26 or 26a) having a peripheral skirt (36) has an inner surface formed with single or multiple threads (38 or 38a) corresponding in number to the threads on the container for engaging the threads on the container. A deflectable release element (50 or 50a) is formed integrally on the container. The release element includes an integral axially deflectable lug (54 or 54 a) extending upwardly toward the open end of the container. The closure has at least one locking lug (44 or 44a) on the skirt of the closure, the number of locking lugs preferably corresponding to the number of threads on the container and closure. The deflectable lug on the deflectable release element normally extends upwardly for engagement with the locking lug such that when the release element is pressed radially inwardly, the lug is disengaged from engagement with a locking lug and the closure can be removed by unthreading the closure from the container. When the closure is reapplied minimal torque is required due to the axial deflection of the deflectable lug and one of the locking lugs on the closure moves past the lug. The deflectable release element and container include interengaging stops (70,72) to limit the deflection on the release element.
