ABSTRACT:
A child-resistant container according to the present invention comprises 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. A cylindrical ledge of slightly increased diameter is provided on the container body longitudinally adjacent the splines. The ledge prevents a user from 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. In one embodiment, the closure is formed as a cup, and the closure must be separated from the container body in order to remove objects contained therein. In another embodiment, the closure has a side wall aperture which is unblocked to form a dispensing orifice when the closure is in the open position. The closure wall aperture is formed by relieving or omitting a portion of the cylindrical side wall of the closure from a bottom edge of the aperture through the top wall, with side edges extending parallel to a longitudinal axis of the closure.
