Abstract
Abstract An improved growth container and method for growing a plant to be transplanted are provided. The interior of the side walls of the container have a lattice of root-trapping recesses therein each having a trough with a pointed end for directing roots growing therein downwardly and outwardly so as to form trapped lateral root tips. The side panels can be disconnected and moved laterally apart to prevent damage to the root tips trapped in the recesses.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
127 words
A container for a plant intended to be transplanted, comprising: a set of upwardly extending side panels each having an interior surface and an exterior surface, and each having vertically extending edge joints adapted so that said side panels can be joined together to form a container with an open top and further adapted so that said joined side panels can be disconnected and moved laterally outwardly apart; and said interior surface of each of said side panels having a lattice of root trapping recesses therein, each of said recesses including a wall that extends from the interior to the exterior of said side panel and a laterally extending trough which connects with said wall forming growing therein downwardly and outwardly so as to be trapped therein.
Claim 2
Dependent Claim
127 words
A container for a plant intended to be transplanted, comprising: a set of upwardly extending side panels each having an interior surface and an exterior surface, and each having vertically extending edge joints adapted so that said side panels can be joined together to form a container with an open top and further adapted so that said joined side panels can be disconnected and moved laterally outwardly apart; and said interior surface of each of said side panels having a lattice of root trapping recesses therein, each of said recesses including a wall that extends from the interior to the exterior of said side panel and a laterally extending trough which connects with said wall forming growing therein downwardly and outwardly so as to be trapped therein.
Claim 3
Dependent Claim
45 words
The container of claim 1 wherein each of said recesses has outwardly extending sides, the bottom of which sides forms said trough and wherein each of said recesses has an interior facing wall which slants downwardly and outwardly to the pointed end of said trough.
Claim 4
Dependent Claim
18 words
The container of claim 2 wherein said outwardly extending sides of said recesses have a generally rhombohedron shape.
Claim 5
Dependent Claim
21 words

Claim 6
Dependent Claim
24 words
The container of claim 4 wherein at least two of said panels have handle openings therein for manual grasping and carrying of said container.
Claim 7
Dependent Claim
28 words
The container of claim 1 which further comprises a bottom panel, the periphery of which joins with said side walls to form the container with an open top.
Claim 8
Dependent Claim

The container of claim 6 wherein said bottom panel rests upon a ledge extending from the bottom of said side panels.
Claim 9
Dependent Claim
25 words
The container of claim 7 wherein said side panels are comprised of plastic and wherein said bottom panel is comprised of a decomposable organic material.
Claim 10
Dependent Claim
22 words
The container of claim 8 wherein said side panels and said bottom panel are generally rectangular and form a generally cuboid container.
Claim 11
Dependent Claim
85 words
In an open-topped container for growing a plant intended to be transplanted having a bottom wall, and an upwardly extending side wall connected thereto, the improvement which comprises said side wall having a wall that extends from the interior to the exterior of said side panel and a lattice of root-trapping recesses therein, each of said recesses having a laterally extending trough which connects with said wall forming a pointed end for directing roots growing therein downwardly and outwardly so as to be trapped therein.
Claim 12
Dependent Claim
85 words
In an open-topped container for growing a plant intended to be transplanted having a bottom wall, and an upwardly extending side wall connected thereto, the improvement which comprises said side wall having a wall that extends from the interior to the exterior of said side panel and a lattice of root-trapping recesses therein, each of said recesses having a laterally extending trough which connects with said wall forming a pointed end for directing roots growing therein downwardly and outwardly so as to be trapped therein.
Claim 13
Dependent Claim
45 words
The container of claim 10 wherein each of said recesses has outwardly extending sides, the bottom of which sides forms said trough and wherein each of said recesses has an interior facing wall which slants downwardly and outwardly to the pointed end of said trough.
