VALVE FOR VESSEL

Abstract:

The innovation described herein generally pertains to a valve for use in allowing material to flow into a vessel. The valve can be constructed from a cylinder of thin-film plastic and can be inserted into and adhered to the inside of a neck of the vessel. Pressure inside of the vessel causes the outlet of the valve to constrict or collapse, preventing material from flowing back through the valve from within the vessel when inflation pressure is removed.
