ABSTRACT:
A squeeze bulb dropper assembly is combined with a child resistant closure to form an assembly which cannot be readily removed by younger children. The assembly provides a vapor proof and leakproof connection with the bottle. The preferred assembly employs a closure having an outer cap and an inner cap in which the inner cap rotates with the outer cap in an application direction, but remains stationary relative to a bottle to which it is engaged when the outer cap is rotated in a removal direction unless a simultaneous downward force is applied to the outer cap to intermesh cooperating members on the caps. The closure includes a dropper bulb disposed through the caps so that a resilient compressible flange on the bulb provides the spacing between the cooperating members of the caps unless a downward pressure on the outer cap compresses the flange.
