ABSTRACT:
A method of manufacturing a dispenser for depositing a liquid material onto a print medium wherein a circular tube having a substantially uniform wall thickness is formed of moldable plastic material. The tube is placed in a mold cavity having a portion for receiving the tube in interfitting engagement and an enlarged cavity portion extending outwardly from the wall of the tube. Pressure is applied to the internal walls of the tube with the tube in plastic flow condition to expand the tube walls into the cavity forming a bulbous portion having a wall thickness less than the tube uniform wall thickness to provide a squeezable portion of greater flexibility than the remainder of the dispenser body.
