ABSTRACT:
A child-resistant container according to the present invention has a container body and a cup-shaped closure which is installed telescopically over the open end of the container body. Mating longitudinal splines and ribs are provided on the adjacent walls of the container body and the closure to interfere with one another as the closure is longitudinally urged from a closed position to an open position. The spline and rib patterns are selected so that the splines and ribs interfere unless the closure is oriented in a predefined angular unlocked position with respect to the container body. The splines and ribs may be irregularly sized or circumferentially spaced along the walls. A cylindrical ledge of slightly increased diameter is provided on the container body longitudinally adjacent the splines. Additional interference ledge segments may be provided on the container body and the closure on or between the splines and ribs. The interference ledge and segments prevent a user from mechanically discovering the unlocked position by rotating the closure and feeling reduced resistance when the unlocked position is reached. A cylindrical plug seal is extends from a top wall of the closure to engage the open end of the container body when the closure is in the closed position.
