Abstract
A dispensing closure having a cap adapted to be mounted upon a container and a spout mounted on the cap so as to be capable of being moved between an open and closed position can be made child resistant through the use of an engagement structure on the spout such as, for example, a notch in the base of the spout located so that a vertically directed force exerting against the engagement structure will not tend to move the spout from the closed position. The cap and the spout employed should be dimensioned so that the spout is incapable of being manually engaged so as to be manipulated when in the closed position.
