Abstract
An apparatus and method is provided for sealing a balloon. The apparatus includes a body for placing in the balloon that is buoyant in water and which has an outer surface that can form a water-tight seal with the inside surface of the balloon. When the balloon is filled with water, the body floats to the top of the water and, if the balloon is filled sufficiently, seals against the opening of the balloon.
Claims21
A device for sealing a balloon filled with a pressurized fluid, where said balloon has an interior volume and has an opening with a first size when said balloon is not pressurized, said device comprising:
- a body adapted to be placed within said interior volume, where said body is sized to not fit through the first size of the opening,
- such that when the pressurized fluid is provided into the interior volume of said balloon and said body is adjacent to said opening, said body forms a seal with the interior surface.
An apparatus comprising:
- a balloon having an interior volume and an opening with a first size when said balloon is not pressurized with a fluid;
- and
- a body within said interior volume, where said body and is sized to not fit through the first size of the opening,
- such that when the fluid is provided into the opening of the balloon and said body is adjacent to said opening, the body floats towards the opening and seals with the interior surface.
A method of sealing a balloon, where said balloon has an interior surface and an opening with a first size when said balloon is not pressurized, said method comprising:
- providing a sealing device to the interior of the balloon, where the sealing device is movable within the interior of the balloon,
- attaching the opening of the balloon to a source of a pressurized fluid;
- filling the balloon with fluid;
- and
- detaching the opening of the balloon from the source of fluid,
- where the pressurized fluid forces said sealing device against the opening of the balloon, and where the detaching the opening results in the sealing device forming a fluid-tight seal for the balloon.
