ABSTRACT:
Pizza sauce is contained in a vat and is deposited onto a pizza through resiliently flexible tubes having upper end portions leading from the vat and having intermediate portions disposed in a pressure chamber. When the chamber is pressurized, the intermediate portions of the tubes are squeezed closed and hold the sauce in the upper portions of the tubes. Upon de-pressurization of the chamber, the intermediate portions of the tubes automatically flex open and allow the sauce to flow out of the tubes and onto the pizza. Different ones of the tubes may be selectively permitted to flex open so as to enable the sauce to be discharged in patterns of different diameters.
