An improved retractable liquid dispenser device comprises an outer body having an internal channel communicating with an open first end. A liquid dispenser includes a supply reservoir and a discharge reservoir with a valve disposed therebetween. A retractable mechanism slidably supports the liquid dispenser within the outer body. A retractable valve is located in proximity to the open first end of the outer body. A first depression of the retractable actuator opens the retractable valve and moves the liquid dispenser into the extended position for enabling a depression of the distal end of the liquid applicator to open the dispensing valve to permit liquid to flow from the supply reservoir into the dispensing reservoir to dispense the applicator liquid from the distal end of the liquid applicator. A second depression of the retractable actuator moves the liquid dispenser into the retracted position and closes the retractable valve to enclose the distal end of the liquid applicator within the outer body.

Pen-type hazardous material applicators are provided useful in applying metal pretreatment material to intricate geometries, such as blind holes, through holes, rivets, crevices, chamfers, counterbores, countersinks and other difficult to access surfaces are provided.

A liquid applicator device is disclosed for dispensing a liquid. A dispensing mechanism defines a valve body hollow. The dispensing mechanism receives the liquid from a liquid container. A closure engages with the liquid container. An applicator tip slidably engages within the closure. A flared peripheral shoulder is coupled to a valve element. The flared peripheral shoulder is impressed against the valve body hollow for preventing the liquid from exiting the dispensing mechanism. The flared peripheral shoulder is displaced for permitting the flow of the liquid from the dispensing mechanism and to the applicator tip. In a first embodiment of the invention, the flared peripheral shoulder includes a non linear protrusion for preventing leakage of the liquid from the dispensing mechanism. In a second embodiment of the invention, a valve flow regulator is coupled to the valve element for controlling the flow of the liquid from the dispensing mechanism.
