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.

In a container for edible viscous food products such as ketchup, mustard, melted cheese or the like; a housing for a pump comprising a plunger, and for a dispenser having a base and a spout, and for a valve apparatus, comprising: a pump chamber having a first end, with an opening in the first end of the pump chamber being sized to removably receive the pump plunger; the housing further comprising a dispensing chamber having a first end with an opening in the first end of the dispensing chamber, the dispensing chamber being sized to receive part of the dispenser base; the housing having a passage connecting the pump chamber and dispensing chamber to provide flow communication of viscous food product between the pump chamber and the dispensing chamber, the passage having a first end with an opening that opens into the pump chamber and a second end with an opening that is in flow connection with the dispensing chamber, with the opening of the first end of the said passage positioned below the opening at the second end of said passage; first valve means associated with the pump chamber for causing the pump chamber to be in flow communication with the food product in the container during a pump plunger upstroke and sealing the pump chamber from flow communication with the food product in the container during a pump plunger downstroke, said first valve means comprising a first movable ball; second valve means associated with the dispensing chamber for sealing the dispensing chamber from flow communication with the passage during a pump upstroke and allowing the dispensing chamber to be in flow communication with the flow passage during a pump downstroke, comprising a second movable ball; means for upwardly checking the movement of the first valve means during pumping intake, and means for checking the second valve means during dispensing and for holding the dispensing means against movement relative to the housing dispensing chamber, comprising a U-shaped pin with a first leg that passes through the housing into the pump chamber with said first leg engaging the first ball during a pump upstroke to check upwardly movement of the first ball, and a second leg which passes through the housing into the dispensing chamber and through the dispenser base to hold the dispenser to the housing, said second leg engaging the second ball during a pump downstroke to check upward movement of the second ball; and the pump chamber having a generally vertical axis and the dispensing chamber having a generally vertical axis, with the flow passage extending at an angle of about 44°to about 38°relative to the axis of the pump chamber.
