Abstract
The oxidation resistance of elastomeric balloons made from natural rubber is greatly improved by coating the exterior of the balloon with a film of uncured elastomer, preferably neoprene. The uncured elastomer coating maintains the clarity of the inflated balloons. These balloons are particularly useful as containers for gifts or in balloon sculpture.
Claims10
The method for manufacturing a transparent natural rubber inflatable and expandable toy balloon having superior resistance to oxidation when the balloon is in an expanded state comprising forming a natural rubber toy balloon;
- coating an exterior surface of said balloon with an optically clear, uncured elastomeric coating;
- and
- drying said coating without curing said elastomeric coating whereby said uncured elastomeric coating retards oxidation opacification of said transparent natural rubber toy balloon when inflated.
A natural rubber toy balloon having an exterior coating of an optically clear, uncured elastomer wherein said balloon is transparent when in an inflated state and is expandable to about 5,000 percent on a surface area basis from an uninflated state to the inflated state;
- and wherein said coating retards oxidative opacification of said balloon in the inflated state.
