Abstract
An inflated non-latex, portable balloon has an internal lamp or transducer connected to an external battery. The balloon is made from an open-necked balloon body formed from panels of balloon material having inner polyethylene layers heat sealed together along peripheries. A pair of flat, metal conductor leads are hermetically sealed in polyethylene to extend in parallel to provide a discrete integral elongate, strip form lead member which is located extending through the open neck with one end supportingly connecting the lamp within the body. The balloon body is inflated and the neck hermetically sealed with the lead member by heat/pressure or ultrasonics thereby fusing together polyethylene surfaces of the lead member and the balloon panels to provide a hermetic seal; and, a battery is connected to ends of the leads outside the balloon.
