COVER TILE FOR TREATING A SUBSTRATE WITH A FLUID

摘要

A cover tile/substrate construct that includes a cover tile having an upper surface, an opposing lower surface, a proximal edge, a distal edge, and a longitudinal direction extending from the proximal edge to the distal edge, wherein the lower surface defines a three-dimensional surface that includes a protrusion that extends in the longitudinal direction; a substantially planar substrate having an upper surface and an opposing lower surface; and wherein the cover tile is juxtaposed over the substrate so that the lower surface of the cover tile and the upper surface of the substrate together define a wedge-shaped capillary fluid flow gap and the longitudinally extended protrusion of the lower surface of the cover tile protrudes towards the upper surface of the substrate.
