Abstract
The present invention relates to a self-sealing refillable plastic balloon valve produced from at least two sheets of plastic film of equal size and shape, cut and heat sealed to form an elongated plastic fill having an operable channel between an inlet and outlet end. The elongated plastic fill valve being affixed to a plastic balloon stem interior and being capable of cyclic self-sealing and reinflation operation of the balloon body. The plastic balloon valve which is capable of multiple self-sealing and refilling cycles, functions through the use of internal self-sealing means either singly or in combinatoin. The self-sealing refillable plastic balloon valve is mounted within a balloon neck with the outlet end extending into the body of the balloon. During assembly of the balloon, the valve can be mounted within the neck in a manner such that the heat bonding does not close the interconnecting channel from inlet to outlet ends of the valve. Optionally, the balloon valve can be inserted into the balloon neck after the manufacture of the balloon and bonded to the interior balloon neck creating a fixed relationship and a sealable balloon neck to valve combination once the valve self-seals.
