Abstract: A two-piece moisture proof safety container for pills and the like has a rectangular drawer and a cover made of a resilient material. The cover and drawer are in the form of mated boxes in which the drawer is slidably engaged within the cover by meshing flanges on the facing surfaces of inside surfaces of sides of the cover and corresponding outside surfaces of the sides of the drawer. This configuration facilitates the automated filling and assembly of the container. The meshing flanges on the drawer and the cover act as cams and cam followers to resiliently urge the drawer, as it is closed, up into tight contact with the underside of the top of the cover by the proper interference fit, effecting a moisture-proof seal. A small catch is attached to the outside of the rear wall of the drawer. This catch engages a portion of the rear wall of the cover, locking the container closed.

Abstract: 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.
