Abstract
Abstract A stake for identifying a potted plant or seedling and insertable into a soil mixture is formed from a thin, flexible material. The stake includes a generally rectangular body, an integral shaft extending from the body and including at its end, remote from the body a generally triangular-shaped or barbed end integral with the shaft. The stake has a generally curved cross-section and a plurality of raised or embossed ridges extending longitudinally of the stake to increase the rigidity of the stake.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
215 words
An identifying stake for insertion into a soil mixture and which is formable from a thin, flexible material yet sufficiently rigid to permit insertion and also capable of reisiting removal from the soil, said stake comprising: a generally planar body member; a planar shaft-like member having a width substantially greater than its thickness, integral with said body member and extending outwardly therefrom, said body member having a rectangular shape and a transverse dimension substantially greater than the transverse dimension of said shaft-like member; a generally triangular-shaped, planar head portion integral with said shaft-like member and extending outwardly therefrom opposite said body member, the base of said head portion being dimensioned greater than the transverse dimension of said shaft-like member to thereby define a barb, said head portion, said body member and said shaft-like member being generally curved in cross-section to thereby increase the rigidity of said stake; and a plurality of indentations extending longitudinally of said head portion, said shaft-like member and said body member for at least a portion thereof, said generally planar body member further defining a pair of opposed inwardly directed notches in the lateral edges thereof spaced from the end of said planar member opposite said head portion, said notches providing convenient points for the securement of string and the like.
Claim 2
Dependent Claim
215 words
An identifying stake for insertion into a soil mixture and which is formable from a thin, flexible material yet sufficiently rigid to permit insertion and also capable of reisiting removal from the soil, said stake comprising: a generally planar body member; a planar shaft-like member having a width substantially greater than its thickness, integral with said body member and extending outwardly therefrom, said body member having a rectangular shape and a transverse dimension substantially greater than the transverse dimension of said shaft-like member; a generally triangular-shaped, planar head portion integral with said shaft-like member and extending outwardly therefrom opposite said body member, the base of said head portion being dimensioned greater than the transverse dimension of said shaft-like member to thereby define a barb, said head portion, said body member and said shaft-like member being generally curved in cross-section to thereby increase the rigidity of said stake; and a plurality of indentations extending longitudinally of said head portion, said shaft-like member and said body member for at least a portion thereof, said generally planar body member further defining a pair of opposed inwardly directed notches in the lateral edges thereof spaced from the end of said planar member opposite said head portion, said notches providing convenient points for the securement of string and the like.
Claim 3
Dependent Claim
24 words
A stake as defined by claim 1 wherein said indentations are parallel to each other and are equally spaced transversely of said shaft-like member.
Claim 4
Dependent Claim
44 words
A stake as defined by claim 2 wherein said body member includes a plurality of spaced, tendemly arranged perforations extending transversely of said body a distance spaced from the transverse edge of said body opposite said shaft member to thereby define a removable tab.
Claim 5
Dependent Claim
34 words
A stake as defined by claim 3 wherein said indentations define lines separating angularly related portions of said planar body member so that said body member has a generally step-wise, curved configuration in cross-section.
Claim 6
Dependent Claim
32 words
A stake as deined by claim 4 wherein said planar body member, said shaft-like member and said head portion are formed from sheet polyvinyl chloride having a thickness of approximately 0.015 inches.
