Abstract
Apparatus for dispensing plaster and the like in the corners of wallboard structures includes an enclosure having a pressure plate which is used to force plaster through an opening in the enclosure. A transitional wall having a somewhat conical or trapezoidal shape is secured to the enclosure around the opening. The smaller open end of the transitional wall forms a transitional orifice having an area which is less than the area of the opening in the enclosure. A spout is secured to the transitional wall around the transitional orifice. The axis of the spout forms an acute angle with the fixed wall, so that the nozzle of the spout is tilted with respect to the enclosure. The transitional wall forms a chamber which permits plaster and the like to be dispensed evenly, with reduced effort, resulting in a smoother surface when the plaster is dispensed. The angle of the spout further improves the even dispensing of the plaster, and permits easy access of the nozzle to corners near ceilings and the like.
