摘要：
A coating material dispensing device includes an orifice for coupling to a reservoir for the coating material. The orifice is surrounded by a surface including at least one wall defining at least one groove. The reservoir includes a complementary surface including at least one wall defining at least one groove. The at least one groove and at least one wall surrounding the orifice respectively receive and are received in the at least one wall and at least one groove of the complementary surface of the reservoir to provide a labyrinth seal between the orifice and an exterior surface of the coating material dispensing device.
