  • Semi-enclosed applicators for distributing a substance onto a target surface
    Publication number: 20050201812
    Abstract: The present invention provides a semi-enclosed applicator for distributing a substance onto a target surface. The applicator has a first side, a second side, and an internal cavity between the first and second sides. The applicator further includes at least one opening, such that the internal cavity is externally accessible, and the applicator further comprises: (a) a material comprising absorbent and substantially non-absorbent fibers on one of the first and second sides; (b) an absorbent core on the other of the first and second sides; and (c) a substantially fluid-impervious barrier layer within the internal cavity adjacent the absorbent core. The applicator includes at least one opening, such that the internal cavity is externally accessible, and the applicator further comprises: (a) a substantially fluid-impervious barrier layer within the internal cavity adjacent one of the sides; and (b) a rupturable fluid-containing reservoir located between the barrier layer and the side.
