Abstract

A child resistant dispensing closure can be constructed by modifying a known type of cap and a known type of spout so that the spout fits entirely within an elongated groove in the cap when the spout is in a closed position. When the spout is in such a position the end of the spout which is normally engaged to move the spout between opened and closed positions is located within this groove in the top of the cap facing the interior of a part of the skirt. This part of the skirt is preferably separated from the remainder of the skirt by slits leading from the top of the cap along opposed sides of the part. This part is capable of being temporarily distended by manual manipulation so as to permit spout movement. Preferably such spout movement is initiated by applying pressure to a portion of the spout remote from the noted end of the spout.
