Abstract
Abstract A one-piece extruder plastic guard for protecting young trees, plants, flowers, and the like includes a length of tubular mesh formed by intersecting thermoplastic filaments, the tubular mesh being bonded to an elongated thermoplastic extrudate defining a stake for anchoring the tubular mesh in the ground. The tubular mesh surrounds the plant to be protected while the stake portion of the one-piece structure holds the tubular mesh in a desired position.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
An extruded plastic guard for protection of young trees, plants, flowers, and the like, comprising: first and second sets of parallel thermoplastic filaments intersecting and bonded to one another at said intersections to define a segment of tubular mesh having a longitudinal axis, the filaments of said first set being parallel to said axis and substantially rigid with respect to the filaments of said second set to provide a longitudinally rigid structure adapted to be easily flattened in a dimension normal to said axis; and an elongated thermoplastic extrusion parallel to said axis and bonded to the tubular mesh, said extrusion extending from one end of the tubular mesh to define a stake for anchoring the guard at a desired location.
Claim 2
Dependent Claim
121 words
An extruded plastic guard for protection of young trees, plants, flowers, and the like, comprising: first and second sets of parallel thermoplastic filaments intersecting and bonded to one another at said intersections to define a segment of tubular mesh having a longitudinal axis, the filaments of said first set being parallel to said axis and substantially rigid with respect to the filaments of said second set to provide a longitudinally rigid structure adapted to be easily flattened in a dimension normal to said axis; and an elongated thermoplastic extrusion parallel to said axis and bonded to the tubular mesh, said extrusion extending from one end of the tubular mesh to define a stake for anchoring the guard at a desired location.
Claim 3
Dependent Claim
34 words
An extruded plastic guard as recited in claim 1, including a plurality of said elongated extrusions to define a corresponding number of stakes at spaced locations about the periphery of said tubular mesh segment.
Claim 4
Dependent Claim
117 words
An extruded plastic mesh guard for protection of young trees, plants, flowers, and the like, comprising: a set of first parallel thermoplastic filaments intersecting and bonded to a second, spirally disposed flexible thermoplastic filament to define a segment of tubular mesh having a longitudinal axis, said first filaments being parallel to said axis and substantially rigid with respect to the second filament to provide a longitudinally rigid structure adapted to be easily flattened in a dimension normal to said axis; and an elongated thermoplastic extrusion parallel to said axis and bonded to the tubular mesh, said extrusion extending from one end of the tubular mesh to define a stake for anchoring the guard at a desired location.
Claim 5
Dependent Claim
117 words
An extruded plastic mesh guard for protection of young trees, plants, flowers, and the like, comprising: a set of first parallel thermoplastic filaments intersecting and bonded to a second, spirally disposed flexible thermoplastic filament to define a segment of tubular mesh having a longitudinal axis, said first filaments being parallel to said axis and substantially rigid with respect to the second filament to provide a longitudinally rigid structure adapted to be easily flattened in a dimension normal to said axis; and an elongated thermoplastic extrusion parallel to said axis and bonded to the tubular mesh, said extrusion extending from one end of the tubular mesh to define a stake for anchoring the guard at a desired location.
