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.

A child-resistant closure unit which comprises: (1) a container, said container closed at one end thereof and having a generally circular opening at the other end thereof, the periphery of said opening having a raised downwardly curved surface, and (2) a resiliently flexible, generally circular, releasable cover for snap-fit engagement with said opening, said cover comprising: (a) a generally circular planar member, said planar member having a bottom surface and a top surface, said bottom surface having reinforcement means extending through approximately its center in opposite directions towards the periphery thereof, (b) a first raised rim adjacent the periphery of said planar member on its bottom surface, said first raised rim having a diameter greater than that of said planar member, said first raised rim elevated a distance beyond the bottom surface of said planar member so as to engage the bottom of said curved surface when said cover is engaged in said opening; (c) a second raised rim adjacent the periphery of said top surface of the planar member, said second raised rim elevated a distance beyond said planar member so as to rest upon said curved surface when said cover is engaged in said opening, and said second raised rim having a diameter greater than that of said planar member and greater than that of said first raised rim; (d) a flange connecting said first and second raised rims, and (e) a tab extending outwardly from said first raised rim, said tab generally in alignment with said reinforcing means, said cover being capable of being pressed in said opening at any rotatable position to close the opening and disengaged by application of sufficient downward force at approximately the center of the planar member, while said tab is simultaneously pulled in a generally upward direction.
