ABSTRACT:
This liquid applicator provides a container having a valve assembly. The valve assembly includes a closure having a passage with a partition dividing the passage into first and second portions and providing a valve opening. A plunger provides a valve element which has an intermediate tapered portion received within the partition opening to provide flow of liquid from the container. A spring overfits the plunger and engages a retainer at the end of the closure and a nib interfits the closure first passage to engage the plunger to provide longitudinal movement of the plunger to open the valve assembly to dispense liquid from the container and into the nib when pressure is applied to move the plunger out of the valve opening.
