Abstract
Abstract The disclosure is directed to a safety closure device for liquid containers which prevent a child from placing his mouth in contact with the discharge neck of the container but permit the contents to be poured freely. The device is comprised of a number of legs which may be connected to the cap and extend down into the bottle in the closed position. In the open position feet or lower members of the legs engage the inner surface of the neck at the bottom and lugs engage the upper surface of the neck preventing the cap from being withdrawn or pushed back into the bottle until a compression force is applied to the legs. The cap is supported on the ends of the legs above the lugs at a sufficient distance so that a child''s mouth placed over the cap cannot engage the neck of the bottle to permit drinking of the contents.
