Abstract

Abstract A plant container having a plurality of downwardly extending compartments, each retaining a dirt ball having the root structure of a growing plant. Each compartment has an open top end and side walls converging downwardly and terminating at the bottom end of the compartment. The bottom end of the compartment is constructed of thin material and is slitted to form yieldable flap members that can bend reverse inwardly on themselves so that an ejecting plunger can be moved upwardly through the bottom of the compartment to eject the dirt ball without damaging its structural integrity.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 227 words
A plant container comprising a body member having a plurality of downward extending compartments, each compartment having an open top end and being adapted to contain a dirt ball having the root structure for a growing plant contained therein, downwardly converging curved side walls terminating at a rounded bottom end of each compartment, at least a portion of said side walls being generally upright above said rounded bottom end, the bottom end of each compartment being formed of thin yieldable material and having criss-crossed slits formed therethrough extending upwardly from said bottom end and into said upright portion of said curved side walls, said slits defining and giving yieldability to a plurality of upwardly and inwardly bendable V-shaped flap members having end portions located essentially at the center of said rounded bottom end and sides diverging radially outwardly and upwardly therefrom so that said flap members curve upwardly from said center location of said bottom end, at least a portion of each of said flap members being generally upright in general alignment with said upright side walls, the thin yieldable and curved construction of said flap members enabling the reverse inward bending of said flap members on themselves establishing an opening when an ejecting plunger is moved upwardly through said bottom end to eject the dirt ball and root structure therein without damaging the structural integrity thereof.
