Abstract
Abstract A toy, packaging, key, jewel, floating gear and architectural geodesic device is provided in the form of a three dimensional package whose outer surfaces are defined by wrapping a flat sheet cut selectively from an even number of connected conical and triangular segments into a closed package with all edges in contact with another edge of the sheet.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
103 words
A toy, packaging, key, jewel, floating gear and architectural geodesic device having a constant center of gravity and at least one continuous substantially curvilinear surface comprising a three dimensional package whose outer surfaces are defined by wrapping a flat sheet cut selectively from an even number of connected arcuate segments of one kind formed into conical segments, mixed arcuate segments of two kinds formed into conical segments, arcuate segments of one kind formed into conical segments mixed with an even number of rectangular segments formed into cylindrical segments into a closed package with all edges in contact with another edge of the sheet.
Claim 2
Dependent Claim
103 words
A toy, packaging, key, jewel, floating gear and architectural geodesic device having a constant center of gravity and at least one continuous substantially curvilinear surface comprising a three dimensional package whose outer surfaces are defined by wrapping a flat sheet cut selectively from an even number of connected arcuate segments of one kind formed into conical segments, mixed arcuate segments of two kinds formed into conical segments, arcuate segments of one kind formed into conical segments mixed with an even number of rectangular segments formed into cylindrical segments into a closed package with all edges in contact with another edge of the sheet.
Claim 3
Dependent Claim
28 words
A toy, packaging, key, jewel, floating gear and architectural geodesic device as claimed in claim 1 wherein the flat sheet is formed from four half right circular cones.
Claim 4
Dependent Claim
53 words
A toy, packaging, key, jewel, floating gear, and architectural geodesic device as claimed in claim 1 wherein the flat sheet is formed from two adjacent intermediate half right circular cones and two spaced apart half right circular cones with the intermediate conical segments connected to the spaced conical segments by a cylindrical segment.
Claim 5
Dependent Claim
67 words
A toy, packaging, key, jewel, floating gear and architectural geodesic device as claimed in claim 1 wherein the flat sheet is formed from two adjacent intermediate half right circular cones and two spaced apart half right circular cones with the intermediate conical segments connected to the spaced conical segments by two pairs of frusto conical segments in which the segments of each pair be in opposite directions.
Claim 6
Dependent Claim
11 words
A toy as claimed in claim 1 formed of rigid plastic.
Claim 7
Dependent Claim
11 words
A toy as claimed in claim 2 formed of rigid plastic.
