Abstract
Abstract A plant stem protector comprising a one-piece generally tubular member made of self-sustaining but deformable plastic in the general form of a cylinder slit from end to end thereof, said cylinder having open ends with an outstanding flange at one end and at the opposite end it is cut into a concave arcuate conformation providing relatively sharp points adjacent to the slit. These points form entry end edges that overlap each other slightly.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
159 words
A plant stem protector comprising a one-piece plastic yielding but self-sustaining member in the form of a cylinder having a longitudinal slit providing separable edges for opening the device in a general direction at right angles to its axis for placing the member about a plant stem, the plastic material tending to return to its original shape upon release thereof, said edges originally being slightly overlapped, the cylinder being open at both ends and having a ground entry end and an opposite end, wherein the ground entry end edges are inclined toward each other relative to the axis of the cylinder forming sharp points, the latter being overlapped to a greater degree than the remainder of the separable edges, so that when the protector is entered into the ground the resistance of the earth on said entry end edges tends to cause the edge portions of the entry end of the device to become overlapped to a greater degree.
