Balloon inflation valve
First Claim
1. An inflation valve for filling an inflatable member with a pressurized fluid comprisinga valve body defining a longitudinal passage and at least one fill port communicating with said passage, said fill port formed through a sidewall of said body transversely of said passage,fill tube means, defining a conduit having an open distal end, insertable into said passage for movement from a first position to a second position longitudinally displaced from said first position,first sealing means disposed in said passage for applying sealing pressure radially inwardly on said fill tube means for maintaining said open distal end in open communication with said fill port when said tube means is in its first position, andsecond sealing means disposed in said passage for applying sealing pressure radially inwardly on said fill tube means for sealing-off communication of said open distal end with said fill port when said tube means is moved to its second position, said fill port being positioned longitudinally between said first and second sealing means.

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.

1. An inflation valve for filling an inflatable member with a pressurized fluid comprising
a valve body defining a longitudinal passage and at least one fill port communicating with said passage, said fill port formed through a sidewall of said body transversely of said passage, fill tube means, defining a conduit having an open distal end, insertable into said passage for movement from a first position to a second position longitudinally displaced from said first position, first sealing means disposed in said passage for applying sealing pressure radially inwardly on said fill tube means for maintaining said open distal end in open communication with said fill port when said tube means is in its first position, and second sealing means disposed in said passage for applying sealing pressure radially inwardly on said fill tube means for sealing-off communication of said open distal end with said fill port when said tube means is moved to its second position, said fill port being positioned longitudinally between said first and second sealing means.

13. A balloon having an inflatable chamber defined therein and an inflation valve mounted in sealing relationship within a stem of said balloon for selectively inflating said chamber with a pressurized fluid, said inflation valve comprising
a generally cylindrical valve body secured within the stem of said balloon, said valve body defining an elongated and longitudinally extending passage and at least one fill port, formed through a sidewall of said valve body transversely of said passage, intercommunicating with said passage and the inflatable chamber of said balloon, a fill tube reciprocally mounted in said passage and having an open distal end movable from a first position to a second position, longitudinally displaced from said first position, an annular and deformable first bead seal formed internally within the passage of said valve body to project radially inwardly into sealing relationship about said fill tube when the open distal end of said fill tube is in each of its first and second positions and longitudinally positioned within said passage to communicate the open distal end of said fill tube with said fill port when said distal end is in its first position, and a second annular and deformable bead seal formed internally within the passage of said valve body to project radially inwardly into sealing relationship about said fill tube when the open distal end of said fill tube is in its second position to seal-off communication of the open distal end of said fill tube with said fill port, said fill port positioned longitudinally between said first and second bead seals.
