A child-resistant closure for a container having a neck and a mouth covered by a flexible cap of inverted cup shape. The container neck includes an outwardly projecting, ramped rib having a lower ramp end. The cap has at least one projection extending inwardly from a sidewall, with the projection being normally positioned radially spaced outside of the ramped rib, but being manually movable inwardly with the side wall to engage the ramped rib near the lower end in a predetermined rotational position of the cap. A detent member hold the cap in a position closing the container mouth but permitting cap rotation. The sidewall may be squeezed to engage the projection and ramped rib, and rotated in one direction, with the ramped rib raising the projection, to force the cap upwardly to open the container by disengaging the detent member from its cap-holding position.

[ I claim:] [1.] A child-resistant closure comprising a container having a top portion with a projecting neck and mouth covered by a flexible cap of inverted cup shape, and a detent member comprising a cap annular rib extending inwardly from the cap interior and a container annular rib extending outwardly from the container neck above the cap annular rib holding the cap in a position closing the container mouth but permitting cap rotation, said neck having a generally rounded periphery in cross section including at least one vertical flat surface, said inverted cap having a top, a sidewall with an internal surface and a peripheral base in confronting relation with said container top, said neck having an outwardly projecting integral rib comprising a circular portion parallel with said container peripheral base and with a ramp end on said flat surface angled toward said cap peripheral base to space said ramp end at a greater distance from said internal cap surface than the spacing of said circular portion, said cap having at least one projection extending inwardly from said cap internal surface at a location between said cap peripheral base and below said circular rib portion, whereby said sidewall may be squeezed to engage said projection and ramp end and rotated with the cap in one direction with the ramp end raising the projection to force the cap upwardly to open the container by disengaging the detent member from its cap-holding position.
