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.
