ABSTRACT:
A safety cap and container is disclosed which is resistant to accidental opening. Such a cap and container include cooperating ratchet means on the cap and the container which normally hold the cap against undesired movement with respect to the container. A tapered internal surface is provided in the container and an internal resilient dependent member is provided on the cap so as to engage the tapered surface. Such engagement normally holds the ratchet means so that the cap cannot be moved with respect to the container. When, however, pressure is applied to the cap above the dependent member, this member is deflected by the tapered surface so as to allow movement of the cap so as to disengage the ratchet means, permitting the cap to be removed from the container.
