ABSTRACT:
A toy hot air balloon constructed of a plurality of elongated gores fashioned from light-weight, thin material. Each of the gores has an opposed pair of long and short edge portions. The gores are sealed in side-by-side configuration at the long edge portions to form an enclosure having a top portion and bottom portion. The bottom portion includes an opening for the admission of hot air. The balloon further includes a mouth area which is reinforced and possesses a higher stiffness than the remaining portion of the enclosure. Each of the ends of the gores are fastened to the mouth of the enclosure. A support permits the suspension of the toy hot air balloon while filling the same with hot air.
