Abstract: Two similar embodiments can dispense condiments from a chamber. A push-valve extends the inside of the chamber through the bottom of the chamber. The valve has an up position which fills and stores a preselected amount of the condiment, and a down position which dispenses the condiment. The valve has an inner cylinder which slides within an outer cylinder. The inner cylinder has an indented area approximating a condiment teaspoon to be dispensed. The outer cylinder has a first hole located inside the chamber. The first hole is aligned with the indented area during the fill position. The outer cylinder has a second hole beneath the chamber so the indented area is aligned with the second hole during the dispensing position. In the first embodiment, a plunger rod attached to the top of the inner cylinder has a spring wrapped around it. Depressing the plunger moves the inner cylinder from the fill to the dispensing position.
