ABSTRACT:
A fluid dispenser having a handle portion supporting at least three spaced-apart, flexible prongs or tines that meet at a pyramidal apex to form a fluid-containing cradle. The cradle holds a precise amount of fluid therein by surface tension between the prongs and the fluid. The small cradle pocket formed at the apex of these prongs has a capillary channel disposed ahead of it, which terminates at the tip of the prongs. When the tip of the prongs are contacted to a body surface in question and slightly flexed, fluid will flow from the cradle through the capillary channel to this surface.
