Abstract
Abstract A child-proof cap closure for containers. The container has a neck with a partial thread and a flange mounted below the thread. The cap has an annular recessed portion adapted to snap over the flange, and the cap has a partial thread adjacent the narrow portion. The positions of the said two partial threads are chosen so that the cap is snapped over the flange by turning the cap, and at the same time causes the threads to disengage. Therefore, the cap cannot be disconnected from the container by simple unscrewing motion, but only by unscrewing and pulling simultaneously to engage the partial threads.
