ABSTRACT:
A condiment pump having a container and a lid. A cylinder extends downward into the container and contains a piston and a piston rod. A lower ball valve is located near the bottom of the cylinder, and a side arm tube extends from the lower ball valve to the top of the container. An upper ball valve is located at the top of the side arm tube, and a spout extends upward from the side arm tube. A washer plate covers the upper end of the side arm tube and has a eccentric hole and a post. The post extends downward from the washer plate to keep the ball of the upper ball at least a predetermined distance away from the hole. A pin engages one of eight notches in the rim of the washer plate. This allows the washer plate and the spout to be rotated through eight different positions.
