Abstract: An improved device for inflating and illuminating a balloon. The device includes a hollow tube having an air baffle structure integrally molded in its interior. The air baffle structure directs air flowing through the tube out through side openings and into a surrounding balloon. A small aperture also extends through the air baffle structure itself. The aperture is sized so that a double lead wire can pass though the aperture from one side of the air baffle structure to the other. The double lead wire extends past the air baffle structure and is directly coupled to an illumination source at the top end of the tube. A sealant is used to seal the aperture through which the double lead wire passes. As such, an air impervious air baffle structure is provided that allows for the direct electrical connection in between a light source on one side of the air baffle structure and a power supply on the opposite side of the air baffle structure.

Abstract: A device and method for illuminating the interior of a balloon. The device includes an elongated tube that is between three inches and twelve inches in length. A light source, such as an incandescent bulb or an LED, is coupled to one end of the elongated tube. A wire passes through the center of the tube and provides power to the light source. The elongated tube is passed into the collapsible fill conduit of a mylar-type of balloon. The elongated tube supports the light source in the interior of the balloon. The collapsible fill tube collapses around the elongated tube, thereby creating a substantially air impervious seal in between the balloon and the elongated tube. The presence of the wire in the elongated tube enables the light source in the tube to be coupled to a power source outside of the balloon without allowing the air in the balloon from escaping.
