Abstract: A pill container and permanently attached cap form a three-sided prism-shaped safety bottle. The container is provided with a top to which the cap is secured permanently by a large-headed shaft from the cap protruding into the container top through an elongated slot with a detent at each end. A slot in one side of the cap rides on a track protruding from the top of the container. An indented section of the cap fits within a dispenser opening on top of the track. Pushing from one side causes the cap to move laterally along a straight portion of the track while the shaft is forced through the tight slot from the first detent to the second. The cap is then pivoted around the shaft, guided by a curved portion of track. A protrusion on the track stops the cap rotation when the opening is exposed to dispense the pills one at a time therethrough. Strength but not manual dexterity is required for the two discrete opening steps.

The lower rim of the closing cap or the upper rim of the discharge tube mounts a separate background ring, preferably of a different color than the closing cap and discharge tube, and the ring is disposed behind a downwardly extending arrow-shaped indicator on the cap and behind an upwardly extending arrow-shaped indicator on the upper rim of the discharge tube.

Abstract: The invention contemplates safety-closure structure involving threaded engagement of cap and bottle-neck members, wherein coacting lug formations on the respective members have compliantly yieldable cammed latching engagement in approach to a fully-closed relation of the members and wherein, once in the fully-closed relation, a positive-lock relation prevents unthreading rotation of the members. The engaged threads are sized for a quantum of axial lost-motion, and resilient action of a seal which reacts axially between the members is operative to constantly load the cap member to its axially upper limit of the lost motion. The lug formations are of such axially limited extent that, when the members are in their fully-closed relation, an axial depression of the cap member through the lost motion and against the resilient seal action is necessary to free the positive-lock relation of the lugs formations, thus then permitting a thread-off rotary manipulation of the cap member.

Abstract: A safety cap is adapted to assume a locked position on the neck of a container at which an annular cap rib rides within the concavity provided by an annular neck recess. In order to remove the cap, it must first be pulled outwardly to break this interengagement. Thereafter, the cap need only be rotated or turned to free the cap from neck threads. In order to mount the cap on the container neck, the cap is initially twisted to cause interengagement of the threads of the cap with the threads of the container neck. The threads are so arranged that when the cap rib engages the upper part of the neck recess, the last turn will force the rib into the recess and at the same time clear the threads from one another. In this position the cap will turn freely relative to the neck with the cap rib disposed within the neck recess.
