Self-sealing refillable plastic balloon valve

A self-sealing balloon valve capable of multiple self-sealing and refillable cycles, for use with a non-latex balloon having a neck portion and a body, said valve comprising:

• an elongated, flexible plastic valve, the valve formed by register and overlay of at least two sheets of flexible plastic material of equal length having sealed edges, said flexible plastic sheets being formed to define a two sided valve channel from an inlet end portion to an outlet end portion, said inlet end portion being sealed at its outermost end and having an inlet opening in one side of the valve for fluid intake, said inlet opening being positioned inwardly from the outermost sealed end of the inlet portion end, and said outlet end portion having an outlet opening;
• the valve channel having at least one interior surface portion coated with a non-sealable material which prevents the sheets from sealing together and closing the channel when the valve is positioned and heat sealed onto the neck portion of the balloon, said non-sealable material extending longitudinally and inwardly from the inlet opening;
• the valve having at least one self-sealing means along the channel between the inlet opening and outlet opening, said self-sealing means comprising a tapered restriction channel forming a zone of reduced cross-sectional opening which allows the valve to self-seal through a creasing action near the outlet end portion, said zone of reduced cross-sectional opening being positioned between the inlet end portion and the outlet end portion wherein the channel cross-section is reduced providing additional self-sealing means upon compression;
• the self-sealing means being adapted to be sealed by filled fluid pressure from the balloon upon withdrawal of fill pressure from the valve.

• the valve channel having at least one interior surface portion coated with a non-sealable material which prevents the sheets from sealing together and closing the channel when the valve is positioned and heat sealed onto the neck portion of the balloon, said non-sealable material extending longitudinally and inwardly from the inlet opening;
• the valve having a first and second self-sealing means along the channel between the inlet opening and outlet opening, said first self-sealing means comprising a tapered restriction channel forming a zone of reduced cross-sectional opening which allows the valve to self-seal through a creasing action near the outlet end portion, said zone of reduced cross-sectional opening being positioned between the inlet end portion and the outlet end portion wherein the channel cross-section is reduced providing additional self-sealing means upon compression, said second self-sealing means comprising a coating of a reusable adhesive element to at least one of the interior surfaces of the said channel which, when compressed together, seals said channel interior surfaces, the adhesive seal capable of multiple reopen and closure modes between the adhesive element and the opposite interior channel surface;
• the self-sealing means being adapted to be sealed by filled fluid pressure from the balloon upon withdrawal of fill pressure from the valve.
