ABSTRACT:
An inflation valve, adapted for sealed attachment within a stem of a balloon, includes a valve body defining a longitudinal passage for receiving a fill tube therein, such as a straw. Insertion of an open distal end of the fill tube to a first position within the passage will facilitate communication of a pressurized fluid, such as air or helium, through a fill port defined in the valve body and into the inflation chamber of the balloon. After filling, the fill tube is moved axially forwardly to a second position for sealing-off communication of the open distal end of the fill tube with the fill port.
