Abstract

A sealing device for a balloon comprising a thin deformable strip of foil attached to a flexible balloon retainer line, with the strip being of a thickness that it may be readily wound about the neck of the inflated balloon by one's fingers and when in such position being self sustained in such wound condition, to prevent the escape of air or gas through the balloon neck portion, while at the same time attaching the retainer line to the balloon. The foil strip is coated on one side with pressure-sensitive adhesive, one end of the line laid lengthwise on the adhesive and the strip folded to simultaneously form the sealing device and attach the line. The foil may have a thickness of approximately 0.001 to 0.002 inches.

Dependent claims

A combined sealing device and flexible retainer line for a toy balloon, comprising a double wall thickness strip of deformable but self-sustaining foil with the retainer line being non-self-sustaining, as for example string, disposed intermediate the walls of said double wall thickness foil strip, and extending for substantially the full length of said strip as well as extending a predetermined amount of substantially greater length as compared to the length of said strip from an end of said strip, for providing for gripping of the line by the balloon user, said walls of said strip being secured to one another by an adhesive disposed between the same, said adhesive also securing said line to said strip walls intermediate thereof, the wall thickness of said foil being in the range of approximately 0.001 of an inch to 0.002 of an inch, said strip being readily wound or twisted about the neck of an inflated balloon by one's fingers and being self-sustaining in said wound or twisted condition for expeditiously sealing the balloon against the escape of pressure from within the balloon's interior while at the same securely attaching the retainer line to the balloon, said combined sealing device and attached retainer line being readily removable from the balloon neck by unwinding or untwisting said strip.

In combination a toy balloon comprising an inflatable resilient body portion and a neck portion connected to said body portion, and a combined sealing device and flexible retainer line wound or twisted about the neck portion and carried thereby, said sealing device comprising a relatively thin deformable but self-sustaining strip of foil of double wall thickness with said flexible retainer line being non-self-sustaining, as for example string, attached to said strip intermediate the walls of said strip, said line extending for substantially the full length of said strip as well as extending a predetermined amount of substantially greater length as compared to the length of said strip from an end of said strip, for providing for gripping of the line by the balloon user, said walls of said strip being secured to one another by an adhesive disposed between the same, with said adhesive also securing said line to said strip walls intermediate thereof, the wall thickness of each of said strip walls being in the range of approximately 0.001 of an inch to 0.002 of an inch, said strip encircling the exterior of said neck portion and being readily wound or twisted about the neck portion of the inflated balloon by one's fingers, and being self-sustaining in said wound or twisted condition and preventing the escape of air through said neck portion, while securing said flexible retainer line to said balloon, said combined sealing device and retainer line being readily removable from said balloon by unwinding or untwisting said strip from about said neck.

A method of forming a combined sealing device and flexible retainer line for a toy balloon comprising, providing a relatively thin deformable but self-sustaining elongated section of foil having on one side thereof a coating of adhesive, the wall thickness of said foil being in the range of approximately 0.001 of an inch to 0.002 of an inch, laying a non-self-sustaining retainer line such as a string or the like longitudinally of said foil section for substantially the full length of said section with the line extending a predetermined amount of substantially greater length as compared to the length of said section from an end of said section, and then folding said foil section upon itself to form an elongated foil strip of double wall thickness which clasps said retainer line therein, with said adhesive securing the double wall thickness of the foil together and to the intermediate retainer line, said strip being self-sustaining but being readily wound or twisted about the neck of an inflated toy balloon for expeditiously sealing the latter against the escape of pressure from within the balloon and at the same time being operable to securely attach the retainer line to the balloon, with said combined sealing device and attached retainer line being readily removable from the balloon by unwinding or untwisting the strip from about the neck of the balloon.
