Abstract
A single use applicator for dispensing and applying a thin layer of viscous fluid, comprising an outer body of chemically inert deformable material open at one end, a crushable glass ampoule therein containing fluid to be dispensed and applied, and an application element of synthetic fiber strands in said tube, wherein fluids flows by capillary action, with an internal reservoir inside the tube adjacent the ampoule, a fluid control valve welded to the tube at its approximate mid point, to control fluid flow, and an external tip to apply the fluid to an application surface.
