Abstract
Abstract An inflatable plastic construction formed of multiple layers of plastic sheets. Transparent exterior sheets are located adjacent interior sheets with printing substances being disposed between the facing surfaces of the respective sheets. An air holding space is defined between the interior sheets. The assembly is heat sealed all around its periphery with the exception of an area provided for a valve mechanism. The valve mechanism is formed from the sheet material, and it permits the introduction of air but inhibits the release of air whereby the structure remains inflated.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
An inflatable plastic construction comprising multiple layers of plastic sheets, said sheets including at least one transparent sheet having printing on an interior facing surface, and first and second additional sheets, the first additional sheet being positioned adjacent said interior facing surface whereby the printing substance is confined between the transparent sheet and said first sheet while being visible through said transparent sheet, the second additional sheet being positioned adjacent said first additional sheet whereby an air holding space is defined therebetween, a valve mechanism adapted to permit the introduction of air into said space but inhibiting passage of air out of said space, said valve mechanism being formed by at least some of said sheets, and a heat seal extending from said valve mechanism all around the edge of said air holding space whereby the combination of the heat seal and the valve mechanism serve to confine air within said space.
Claim 2
Dependent Claim
152 words
An inflatable plastic construction comprising multiple layers of plastic sheets, said sheets including at least one transparent sheet having printing on an interior facing surface, and first and second additional sheets, the first additional sheet being positioned adjacent said interior facing surface whereby the printing substance is confined between the transparent sheet and said first sheet while being visible through said transparent sheet, the second additional sheet being positioned adjacent said first additional sheet whereby an air holding space is defined therebetween, a valve mechanism adapted to permit the introduction of air into said space but inhibiting passage of air out of said space, said valve mechanism being formed by at least some of said sheets, and a heat seal extending from said valve mechanism all around the edge of said air holding space whereby the combination of the heat seal and the valve mechanism serve to confine air within said space.
Claim 3
Dependent Claim
48 words
A construction in accordance with claim 1 wherein first and second transparent sheets are included in the construction, both of said sheets having printing substances on their interior facing surfaces with the respective additional sheets being located in overlying relationship relative to the surfaces carrying the printing substances.
Claim 4
Dependent Claim
24 words
A construction in accordance with claim 2 wherein said construction comprises a caricature, said valve mechanism being located at the head of the caricature.
Claim 5
Dependent Claim
30 words
A construction in accordance with claim 3 wherein said additional sheets are pigmented to thereby provide a background for areas of the transparent sheets which are free of printing substances.
