Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
127 words
A pneumatic aerial amusement device formed of heat sealable plastic comprising: a first disc of heat sealable plastic; a second concentrically disposed heat sealable plastic disc of like diameter, said first and second discs being heat sealed along their common circumference; a concentric annular seal between said first and second discs having a diameter smaller than the diameter of said discs, said first and second discs defining inwardly of said seal an inflatable cavity, and defining between said annular seal and said circumferential seal a flexible equatorial girdle or rim having an airspace therein, the combined width of said annular seal and said equatorial rim being sufficient to allow for gripping with the thumb and fingers; an inlet to said cavity; and means for plugging said inlet.
