An improved safety container for pills and the like is in the form of a jar with an elastically deformable cylindrical cap of the snap-on and -off type. Mating flanges are provided on the jar and the inside of the cap which, when engaged, captively hold the cap to the jar yet permit the cap to rotate. Special tapers are provided on the mating flanges which act cooperatively under the influence of the elastic restoring forces of the cap to force the top of the cap into tight sealing contact with the lip of the mouth of the jar. This seal is further improved by the provision of mating beveled features on the interior of the top of the cap and the lip of the jar. A tab is provided on the cap to permit the user to apply the necessary force to deform the cap in order to remove it. A locking feature is provided by a keyway cut in this tab designed to engage and ride captively on a locking flange which encircles all but a small portion of the jar. Only in the unique orientation of the tab where an interruption in the locking flange is registered with the tab, is the tab free to move upward, levering off the cap. A safety mechanism is provided in the form of an elastically deformable safety catch affixed to the jar and designed to overhang the tab when it is in the unique orientation.

In combination with a container having a neck terminating in a mouth of substantially circular cross-section; a cylindrical cap having an end closure and being mountable for rotation about said mouth; mating first, second and third flanges, all being at least partial annulae, disposed respectively about said neck proximate said mouth, the inner circumference of said cap, and about said neck distal said mouth so that when said flanges are mated said second flange lies between said first and third flanges for capturing said cap in closing relation to said mouth, Said third flange having a circumferential discontinuity therein; and a tab mounted on and extending radially from said cap so as to be engageable for levering said cap from said neck when said flanges are mated and said cap and neck are in an unlocking position wherein said tab and discontinuity are registered with one another; the improvement comprising a keyway slot disposed in said tab for engaging said third flange upon rotation of said cap about said neck from said unlocking position when said flanges are mated.
