Japanese Patent JPS5634753
Kind Code:
B2
Abstract:
An inflation device adapted to admit compressed gas to the interior of a balloon, and to seal that interior against the atmosphere after inflation, is comprised of a pair of circular disks in parallel alignment and spaced from each other. The disks are rigidly affixed to a central shank which extends beyond one of them. The shank extension is bored with a passage, sealed at the far end thereof, in communication with the annular space between the disks by means of a radial orifice. The tubular neck of the balloon is stretched over the sealing disks, with the shank extension protruding from the opening of the balloon sheath. Upon pressurizing the passage in the shank with air, or other inflating medium, that portion of the balloon stretched between the two disks distends and permits the inflating medium to enter the internal volume of the gasbag around the periphery of the inner disk. The inflation device may be adapted to the inflation of multiple nested balloons by the addition of further sealing disks along the extended shank.
