Abstract

A child-resistant closure unit is provided. The unit includes a container having a generally central opening and a resiliently flexible cover for the opening. The cover has a bottom flange on its periphery which engages the bottom of a curved surface on the periphery of the opening. Simultaneous depression of the cover and the pulling of a tab connected to the top rim of the cover disengages the cover. No specific orientation is required to either engage or disengage the cover.
