Abstract: A locking cap and container is provided for a container having an opening surrounded by a neck with container threads thereon that are sized and located to threadingly engage cap threads formed on a skirt of the cap. A shaped distal end is formed on a distal end of the container threads and a barb is formed on the distal end of the cap threads. A resilient locking tab extends from the container, and is located below the shaped distal end and spaced apart from the shaped distal end a distance sufficient to allow passage of the barb beyond the shaped distal end but sufficiently close to resiliently urge the barb into overlapping rotational alignment with the shaped end. The shaped end is configured to lockingly engage the barb when the tab holds them in alignment. Pushing down on the cap pushes the thread against the locking tab and allows disengagement of the barb from the shaped distal end and movement of the barb past the shaped distal end to unlock the cap.

Abstract: A closure and container combination has in which anti-backoff capability the closure includes a top wall and a depending annular skirt having closure threading formed on an inner surface of the skirt. The closure threads mate with threads on the container. One or more anti-backoff members are formed on the inner surface of the skirt and/or the outer surface of the container neck and arranged and configured to frictionally engage the mating threading between the anti-backoff member and the threading to resist movement of the closure once secured onto the neck of the container.

Abstract: A closure and container combination provide a child resistant package. The closure has a top wall and a skirt depending downwardly from a peripheral edge of the top wall. The container has a bottom, a cylindrical sidewall extending upwardly from the bottom and an open top. An annular flange projects outwardly from the outer surface of the cylindrical sidewall of the container proximate the top of the container. This annular flange has a flexible tab and is positioned below the skirt when the closure and container are mated together. To remove the closure from the container, the flexible tab is pushed upwardly against the skirt thereby lifting the closure off of the container. The flexible tab prevents undesired access through the annular flange and provides leverage to aid removal of the closure. In addition, a child is inhibited by the inflexible flange from using his or her teeth or fingernail to pry open the closure from the container.
