Abstract:
1. An applicator for forming a uniform thickness layer of a liquid coating on a solid substrate comprising: a first housing having a first end and a second end and defining an inner cavity, the first end of the housing terminating in a generally flat widened region with one or more liquid delivery passages in liquid communication between the inside of the cavity and the exterior of the generally flat widened region, a thin layer of liquid-permeable foam conformed over the exterior of the generally flat widened region said thin layer of foam covering and in liquid communication with the liquid delivery passages and retained in that position, two or more sealed frangible containers filled with the coating liquid and located within a pair of opposing fingers which grip the containers inside the inner cavity and the containers movable from a first position to a second position therein, the first position preserving the integrity of the frangible containers and the second position being such that when the two or more containers are moved from the first position to the second position, a frangible-container-breaking force is applied to the containers when the pair of opposing fingers come into contact with two or more ramps each having a slope, wherein not all slopes are in parallel, and the coating liquid is released from the frangible containers and passes through the liquid delivery passages into the thin layer of liquid-permeable foam, a closure for sealing the second end of the first housing, and a movable fixture capable of moving the two or more containers from the first position to the second position within the inner cavity.
