Abstract
Abstract As an article of manufacture, a plug shaped receptacle or hollow container made of peat, pre-shaped and reacted at conditions of temperature and pressure sufficient to cause reaction and polymerization of the naturally occuring functional groups of the peat. In preferred embodiments one or more chemical reagents are also added to react and polymerize with the natural functional groups of the peat and enhance the properties of the so formed peat container.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
124 words
As an article of manufacture, a plug-shaped concontainer made of peat for containing a seed or seedling, formed from a mass of chemically untreated natural peat to which has been added, in concentration ranging between about 0.1 and about 25%, based on the weight of the peat, an amine which contains two or more primary amino functional groups per molecule, said container having been preshaped and reacted at temperature ranging from about 100° to about 500° F and pressure ranging from about 50 psig to about 500 psig sufficient to cause reaction and polymerization between functional groups of said amine and the naturally occurring functional groups of the peat, whereby when planted the roots of the seed or seedling can penetrate through the container.
Claim 2
Dependent Claim
124 words
As an article of manufacture, a plug-shaped concontainer made of peat for containing a seed or seedling, formed from a mass of chemically untreated natural peat to which has been added, in concentration ranging between about 0.1 and about 25%, based on the weight of the peat, an amine which contains two or more primary amino functional groups per molecule, said container having been preshaped and reacted at temperature ranging from about 100° to about 500° F and pressure ranging from about 50 psig to about 500 psig sufficient to cause reaction and polymerization between functional groups of said amine and the naturally occurring functional groups of the peat, whereby when planted the roots of the seed or seedling can penetrate through the container.
Claim 3
Dependent Claim
20 words
The article of manufacture of claim 1 wherein the amine contains up to about 60 carbon atoms in the molecule.
Claim 4
Dependent Claim
21 words
The article of manufacture of claim 1 wherein the amine contains from 2 to about 36 carbon atoms in the molecule.
Claim 5
Dependent Claim
30 words
The article of manufacture of claim 1 wherein the amine is added in concentration ranging between about 1 and about 10 percent, based on the weight of the unreacted peat.
Claim 6
Dependent Claim
32 words
The article of manufacture of claim 1 wherein the amine which is added to the mass of peat is dissolved in a solvent prior to its addition to the mass of peat.
Claim 7
Dependent Claim
18 words
The article of manufacture of claim 1 wherein the temperature ranges from about 175° to about 350° F.
Claim 8
Dependent Claim
20 words

Claim 10
Dependent Claim
123 words
As an article of manufacture, a plug-shaped container made of peat for containing a seed or seedling, formed from a mass of chemically untreated natural peat to which has been added, in concentration ranging between about 0.1 and about 25%, based on the weight of the peat, an aldehyde which contains two or more aldehyde functional groups per molecule, said container having been preshaped and reacted at temperature ranging from about 100° to about 500° F and pressure ranging from about 50 psig to about 500 psig sufficient to cause reaction and polymerization between functional groups of said aldehyde and the naturally occurring functional groups of the peat, whereby when planted the roots of the seed or seedling can penetrate through the container.
Claim 11
Dependent Claim
123 words
As an article of manufacture, a plug-shaped container made of peat for containing a seed or seedling, formed from a mass of chemically untreated natural peat to which has been added, in concentration ranging between about 0.1 and about 25%, based on the weight of the peat, an aldehyde which contains two or more aldehyde functional groups per molecule, said container having been preshaped and reacted at temperature ranging from about 100° to about 500° F and pressure ranging from about 50 psig to about 500 psig sufficient to cause reaction and polymerization between functional groups of said aldehyde and the naturally occurring functional groups of the peat, whereby when planted the roots of the seed or seedling can penetrate through the container.
Claim 12
Dependent Claim
