  • Patent number: 5487490
    Abstract: A method and apparatus are provided for dispensing a food product from a plastic squeeze bottle, which includes a bottom, a top, and resilient sidewalls. A displacement orifice extends into the plastic squeeze bottle for passing ambient air into an inflatable element disposed within the plastic squeeze bottle. A check valve retains the ambient air within the inflatable element. The inflatable element has an expandable wall which separates the ambient air from the food product contained within the bottle. Expansion of the inflatable element presses the expandable wall between resilient sidewalls and urges the food product to flow through a dispensing orifice and from the bottle. A dispenser tip extends across the dispensing orifice for passing the food product therethrough, and preventing ambient air from entering the plastic squeeze bottle through the dispensing orifice.
