ABSTRACT:
A toy balloon has an inflation valve secured thereon to selectively fill a chamber of the balloon with a fluid, such as helium. The valve comprises a stem defining a filling passage therethrough for communicating a pressurized fluid source with the inflatable chamber of the balloon and an elastomeric plug reciprocally mounted in the passage for movement in a first direction towards the chamber to openly communicate the passage with the chamber to permit filling thereof and for further movement in a second, opposite direction away from the chamber to seal the passage to prevent escape of the fluid from the balloon. The inner surface of the stem and/or the outer surface of the elastomeric plug may be suitably sized and tapered to permit the sleeve to compress the plug for sealing purposes when it is moved in its second closing direction. An annular bead may be formed internally on the sleeve to compress the plug to form an annular static seal between the sleeve and the plug.
