Inflatable packaging cone and method of making the same
First Claim

1. An inflatable cone formed from a fan-like sealed envelope segmented into successive segment sectors defined by radial sealing lines converging from a circular perimeter edge of the fan radially toward but not reaching the center vertex, leaving a lower V-shaped pocket;
- the envelope being of conical shape with the lower pocket forming the cone vertex to hold the shape and provide an inner storage recess; and
means at the upper perimeter edge of a segment sector for inflating the envelope sectors through said sector into the lower pocket and thence into the other segment sectors to provide the resulting cone with successive scalloped inflated segments.

Abstract
A two-dimensional inflatable heat-sealable thin-film form is provided for creating a three-dimensional inflated cone with a recess in the base of the cone, useful as a carrying pouch or as an end-cap for cushioning, as well as thermal protection. A preferred manufacturing in-line process for making the cone is also described.
