Abstract
A child resistant closure adapted to be used with a container to provide a child resistant package comprising a closure having a base wall and a peripheral skirt with internal threads adapted to engage complementary threads on the container. The closure is provided with a plurality of circumferentially spaced flexible fins which frictionally engage the apex only of an annular bead on the container to provide resistance to closure back off in order to resist unthreading of the closure from the container. The closure is to be provided with a tab which is engageable with a projection on the container to prevent unthreading of the closure except when the tab is depressed. In another form, a cylindrical surface on the skirt frictionally engages solely the apex of the annular bead on the container. The cylindrical surface may be a continuous surface or a series of closely spaced annular serrations and alternating fine grooves. The closure may also be used without a tab to provide a secondary seal on a conventional threaded closure.
