Abstract
Abstract Insulation for liquid gas container and particularly spherical containers is disclosed. Plastic insulating panels having rabbeted edges are arranged in rows over the surface of the container. Each adjacent row is staggered one half panel length. A fastening element is embedded in the center of each panel. A second layer of panels is superposed over the inner layer such that the panels of the upper layer are staggered with respect to the panels of the inner layer and are held in place by means of the fastening elements fastening the rabbeted edges of the upper layer of panels.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
Insulation for liquid gas containers comprising: a plurality of molded inner foamed synthetic insulating panels each having rabbeted edges, each having a fastening element at the center thereof projecting upwardly from approximately halfway through the thickness thereof and each having a forceaccepting element embedded in the center of each panel during molding thereof at approximately half the thickness of said panel; said inner insulating panels being adapted for arrangement on a gas container with each panel being staggered with respect to at least one of the next adjoining panels and interlocking therewith; a plurality of outer insulating panels having rabbeted edges; said outer insulating panels being adapted for arrangement on said inner insulating panels with each outer panel being staggered with respect to at least one of the next adjoining outer panels and interlocking therewith and each said outer panel being staggered with respect to said inner panels; and wherein said fastening elements of said inner panels fit into the rabbeted edges of said outer panels.
Claim 2
Dependent Claim
166 words
Insulation for liquid gas containers comprising: a plurality of molded inner foamed synthetic insulating panels each having rabbeted edges, each having a fastening element at the center thereof projecting upwardly from approximately halfway through the thickness thereof and each having a forceaccepting element embedded in the center of each panel during molding thereof at approximately half the thickness of said panel; said inner insulating panels being adapted for arrangement on a gas container with each panel being staggered with respect to at least one of the next adjoining panels and interlocking therewith; a plurality of outer insulating panels having rabbeted edges; said outer insulating panels being adapted for arrangement on said inner insulating panels with each outer panel being staggered with respect to at least one of the next adjoining outer panels and interlocking therewith and each said outer panel being staggered with respect to said inner panels; and wherein said fastening elements of said inner panels fit into the rabbeted edges of said outer panels.
Claim 3
Dependent Claim
25 words
