SAFETY CLOSURE AND CONTAINER

SAFETY CLOSURE AND CONTAINER Edward W. Owens and Ned J. Smalley A child-resistant liquid seal closure and container combination featuring one or more camming projections on the container neck and one or more locking lugs on the interior surface of the closure which engage the camming projections to prevent rotational removal of the closure from the container. The closure may be removed from the container only by squeezing the closure on opposite sides to force the locking lugs radially outwardly beyond the camming projections to permit rotation of the closure relative to the container. The camming project tions on the container neck are of sufficient axial height to prevent rotation of the closure relative to the container both when the closure is fully tightened onto the container and when the closure has been rotated 180.degree. relative to the container, thereby necessitating two separate squeezing actions to remove the closure from the container. The closure of this invention has an outwardly tapered skirt which, when threadingly engaged on a straight cylindrical neck, provides sufficient space and resiliance to allow for squeezing of the closure to disengage the locking lugs from the camming projections.
