Abstract
A self-sealing balloon comprising a tubular balloon neck segment extending from an opening of a balloon gas retaining expansion cavity. A bead of adhesive material is applied in a loop about an interior circumference of a neck portion of the balloon forming a dispensed adhesive roll. The dispensed adhesive roll is at least partially encapsulated within an adhesive staging segment. The adhesive staging segment is shaped into a loop by at least one roller. The roller extends the balloon neck material and pulls the ring downward, drawing the ring into the adhesive staging segment. The ring aids in forming the loop. In use, the balloon would be inflated. The neck would be stretched, exposing the adhesive ring. The ring would be compressed forming a seal, entrapping pressurized air within the balloon gas retaining expansion cavity. This provides a low cost, simple self-sealing solution for a balloon.
