Abstract
Abstract A biodegradable package for fast food comprises a heat-molded body of a moldable composition which consists essentially of an admixture of fully biodegradable natural materials comprising flour from edible gramineous plants, crushed gramineous hay, a minor proportion of preserving agents, and a plasticizing agent for providing a starting moldable dough suitable for being molded into the shaped fast food package.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
59 words
A biodegradable package for fast food which comprises a heat-molded body of a moldable composition which consists essentially of an admixture of flour from edible gramineous plants, crushed gramineous hay, a minor proportion of preserving agents, and a plasticizing agent for providing a starting moldable dough said body having a thickness from about 1 mm to about 10 mm.
Claim 2
Dependent Claim
59 words
A biodegradable package for fast food which comprises a heat-molded body of a moldable composition which consists essentially of an admixture of flour from edible gramineous plants, crushed gramineous hay, a minor proportion of preserving agents, and a plasticizing agent for providing a starting moldable dough said body having a thickness from about 1 mm to about 10 mm.
Claim 3
Dependent Claim
70 words
A biodegradable package for fast food according to claim 1, wherein said moldable composition consists of from about 6% to about 98% by weight of said flour from edible gramineous plants, from about 2% to about 94% by weight of said crushed gramineous hay, from about 0.02% to about 1.0% by weight of said preserving agents; and an amount of said plasticizing agent sufficient to provide a starting moldable dough.
Claim 4
Dependent Claim
27 words
A biodegradable package for fast food according to claim 1, wherein said flour from edible gramineous plants is selected from corn flour, wheat flour and sorghum flour.
Claim 5
Dependent Claim
27 words
A biodegradable package for fast food according to claim 1, wherein said crushed gramineous hay is selected from corn hay, wheat hay, sorghum hay and corncob leaves.
Claim 6
Dependent Claim
19 words
A biodegradable package for fast food according to claim 4, wherein said crushed gramineous hay comprises crushed corncob leaves.
Claim 7
Dependent Claim
16 words
A biodegradable package for fast food according to claim 1, wherein said plasticizing agent is water.
Claim 8
Dependent Claim
25 words
A biodegradable package for fast food according to claim 1, wherein said preserving agent is selected from the group comprising sodium benzoate and mono-sodium glutamate.
Claim 9
Independent Claim
145 words
A method for the manufacture of a biodegradable package for fast food which comprises the steps of: a) heating pieces of a gramineous plant to a temperature of from about 20° to about 300° C. for cooking the same; b) milling the cooked gramineous plant pieces in the presence of water as a plasticizing agent in order to form a dough of a flour of said milled gramineous plant; c) admixing said dough with suitable amounts of crushed hay of gramineous plants and stirring the mixture until a homogeneous dispersion is obtained; d) adding a minor proportion of preserving agents for preventing a premature decomposition of the dough; e) pouring said dough in a mold and heating to a temperature of from about 50° to 350° C., until the moisture content of said dough is reduced to provide a self-sustaining shaped package for fast food.
Claim 10
Independent Claim
145 words
A method for the manufacture of a biodegradable package for fast food which comprises the steps of: a) heating pieces of a gramineous plant to a temperature of from about 20° to about 300° C. for cooking the same; b) milling the cooked gramineous plant pieces in the presence of water as a plasticizing agent in order to form a dough of a flour of said milled gramineous plant; c) admixing said dough with suitable amounts of crushed hay of gramineous plants and stirring the mixture until a homogeneous dispersion is obtained; d) adding a minor proportion of preserving agents for preventing a premature decomposition of the dough; e) pouring said dough in a mold and heating to a temperature of from about 50° to 350° C., until the moisture content of said dough is reduced to provide a self-sustaining shaped package for fast food.
Claim 11
Dependent Claim
38 words
A method according to claim 8 wherein said dough is fed into the mold with a moisture content of about 50% and the mold is heated until the moisture content of the composition is reduced to about 0.01%.
