Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
A pressurized container comprising: a body having an interior chamber to be pressurized; a rigid cap for compressing air in said interior chamber, said cap being longitudinally and bodily movable relative to said body from an initial position to a completely closed position; first means located between said cap and said body to establish an air-tight connection therebetween, said first means causes establishment of said air-tight connection when said cap and body are in said initial position and maintains said air tight connection during movement of said cap in either direction between said completely closed position and said initial position, thereby resulting in gradual change in pressure in said interior chamber as said cAp moves in either direction between said positions; and second means mounted on both said cap and said body, said second means capable of interlocking to effect movement from said initial position to said completely closed position and to result in securement of said cap upon said body in said completely closed postion.
Claim 2
Dependent Claim
166 words
A pressurized container comprising: a body having an interior chamber to be pressurized; a rigid cap for compressing air in said interior chamber, said cap being longitudinally and bodily movable relative to said body from an initial position to a completely closed position; first means located between said cap and said body to establish an air-tight connection therebetween, said first means causes establishment of said air-tight connection when said cap and body are in said initial position and maintains said air tight connection during movement of said cap in either direction between said completely closed position and said initial position, thereby resulting in gradual change in pressure in said interior chamber as said cAp moves in either direction between said positions; and second means mounted on both said cap and said body, said second means capable of interlocking to effect movement from said initial position to said completely closed position and to result in securement of said cap upon said body in said completely closed postion.
Claim 3
Dependent Claim
40 words

The container as defined within claim 2 wherein: said first thread is on the interior surface of said cap and said second thread is on the exterior surface of said body, said threads becoming coupled at said initial position and remaining coupled during movement of said cap to said completely closed position.
Claim 6
Dependent Claim
49 words
The container as defined in claim 4 wherein: said first means comprises an O-ring seal which is formed of a resilient material, said seal being located between said second means and said interior chamber for all positions of said cap between said initial position and said completely closed position.
Claim 7
Dependent Claim
49 words
The container as defined in claim 1 wherein: said first means comprises an O-ring seal which is formed of a resilient material, said seal being located between said second means and said interior chamber for all positions of said cap between said initial position and said completely closed position.
Claim 8
Dependent Claim
38 words
The container as defined in claim 1 wherein: said cap including an extension, said extension being adapted to matingly cooperate within said interior chamber of said body, said first means being located between said extension and said body.
