Claim:
1. An application device for applying an active agent to a filament material, the application device comprising: a housing defining therein a reservoir volume for storing the active agent, said housing having a proximal end and a distal end; and an applicator defining an application volume for applying the active agent disposed in said application volume to the filament material, said applicator having a proximal end coupled to the distal end of the housing, an opposing free distal end and a concave upper wall and a convex lower wall having a number of hollow teeth formed therein said teeth having base portions and opposing terminal distal ends which define the distal end of the applicator, wherein said teeth extend upwardly and rearwardly along a curved path from the distal ends to the base portions and have a width in a plane transverse to said curved path where said width progressively increases in a proximal direction from said distal ends to said base portions; said teeth providing gaps there between for introducing the filament material into said application volume, said gaps defining rear gap outlets proximate said base portions of said teeth and introduction sections proximate said terminal distal ends of said teeth section, said lower wall defining a lower contact surface with a recess formed therein where at least one of said gaps in an area of said lower wall has a rear gap outlet that extends from said lower contact surface into said recess and wherein said rear gap outlets are positioned at an angle which extends inwardly from a closest area of the lower contact surface in a direction toward the upper wall.
