Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
98 words
A perishable comestible package comprising: (i) a sealed, air-tight, cold permeable container; (ii) a perishable comestible product sealedly disposed within said container; and (iii) a self-contained source of water vapor sealedly disposed within said container, comprising: (a) a substantially flexible water laden porous element having an aperture therein, and, (b) a flexible envelope surrounding and substantially contiguous with said porous element whereby substantially all liquid water is confirmed within said porous element and having aperture means therein, for permitting continuous supplying of water vapor to said container while precluding direct contact between said porous element and said comestible.
Claim 2
Dependent Claim
98 words
A perishable comestible package comprising: (i) a sealed, air-tight, cold permeable container; (ii) a perishable comestible product sealedly disposed within said container; and (iii) a self-contained source of water vapor sealedly disposed within said container, comprising: (a) a substantially flexible water laden porous element having an aperture therein, and, (b) a flexible envelope surrounding and substantially contiguous with said porous element whereby substantially all liquid water is confirmed within said porous element and having aperture means therein, for permitting continuous supplying of water vapor to said container while precluding direct contact between said porous element and said comestible.
Claim 3
Dependent Claim
14 words
The package as defined by claim 1 wherein said porous element is a sponge.
Claim 4
Dependent Claim
12 words
The package as defined by claim 1 in a condition of refrigeration.
Claim 5
Dependent Claim
66 words
The package as recited in claim 1, wherein the aperture means in said flexible envelope is in registration with the aperture in said porous element, and wherein the self-contained source of water vapor is nested within an accommodating void interiorly of said container whereby a continuous supply of water vapor is provided to the interior of said container without causing damage to said perishable comestible product.
Claim 6
Dependent Claim
32 words
The package as recited in claim 1 wherein said self-contained source of water vapor is nested within an accommodating void interiorly of said container without causing damage to said perishable comestible product.
