ABSTRACT:
In a container for dispensing viscous food product having viscosity such as of ketchup, mustard, melted cheese or the like, is a housing for a pump, a dispenser, and valves. The housing has a pumping chamber and dispensing chamber, with first and second valves associated with the pumping and dispensing chambers, respectively. The pump chamber is sized to receive part of a pump. The dispensing chamber is sized to receive part of a dispenser, which can include a base. An angled flow passage connects the pump chamber to the dispensing chamber. The first and second valves can both include a ball. Structure is provided for checking the upward movement of the first and second valves during pumping and dispensing strokes and to hold the dispenser to the housing, which in a preferred embodiment comprises a U-shaped pin which passes into the dispensing chamber and engages the dispenser, and into the pump chamber. A notch in the side of the housing permits easy grasping of the U-shaped pin. The dispensing chamber has a ledge to support the dispenser base that provides a seal against viscous food product flow around the dispenser.
