Abstract
Abstract A parachute is packaged in a sealed chamber between a pair of peripherally sealed plastic sheets and the chamber is evacuated or vacuumized. An elongated pyrotechnic fuze is provided in the chamber surrounding the parachute and when the fuze is detonated, it burns through at least one of the plastic sheets to permit the parachute to be deployed from the package.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
78 words
A parachute package comprising a pair of superposed plastic sheets joined together about their peripheral margins to define a sealed interior chamber; a folded parachute disposed within said interior chamber; an elongated pyrotechnic fuze positioned within said chamber in surrounding relationship to said parachute; and means for detonating said fuze whereupon said fuze will burn through at least one of said plastic sheets to thereby open said chamber and permit said parachute to be deployed from said package.
Claim 2
Dependent Claim
78 words
A parachute package comprising a pair of superposed plastic sheets joined together about their peripheral margins to define a sealed interior chamber; a folded parachute disposed within said interior chamber; an elongated pyrotechnic fuze positioned within said chamber in surrounding relationship to said parachute; and means for detonating said fuze whereupon said fuze will burn through at least one of said plastic sheets to thereby open said chamber and permit said parachute to be deployed from said package.
Claim 3
Dependent Claim
22 words
A parachute package as defined in claim 1 wherein said chamber is evacuated thereby causing said sheets to closely surround said fuze.
Claim 4
Dependent Claim
38 words
A parachute package as defined in claim 2 wherein said plastic sheets are formed of thin, flexible synthetic resinous material and wherein at least a portion of said peripheral margins is joined by heat sealing said sheets together.
Claim 5
Dependent Claim
37 words
A parachute package as defined in claim 2 further including coupling means connected through said package to the parachute therein to enable said parachute to be connected to a remote member even while said chamber remains sealed.
Claim 6
Dependent Claim
63 words
A parachute package as defined in claim 2 wherein said detonating means includes a device having an explosive charge, a striker pin for firing the explosive charge and a port directing the blast from the explosive charge to one of said plastic sheets at a location overlying said fuze whereby said blast can burn through said one plastic sheet to ignite said fuze.
