Abstract

A planting system including a support tray, a plurality of interconnected sleeves, and a plurality of transplant frames adapted for insertion within each sleeve. Each assembly is configured so that a plurality of assemblies are nestable and stackable without jamming relative to each other. Each individual part and sub-assembly is also configured to be nestable in nonjamming relationship with other like parts or subassemblies.

Claims

1. An assembly adapted for growing a plurality of plants intended to be transplanted, said assembly comprising a support tray, a plurality of integrally interconnected sleeves, said tray having sidewalls and a grid-like upper structure, said sidewalls being inclined upwardly and inwardly from an open bottom of said support tray to said grid-like upper structure, said upper structure comprising a plurality of vertical wall means spaced apart longitudinally and laterally of said tray, said vertical wall means defining a first predetermined vertical dimension from the uppermost surface of the grid-like structure to the lowermost surface of the vertical wall means, the sidewalls defining a second predetermined vertical dimension from the uppermost surface of the grid-like structure to the lowermost edge surface of the tray, the second predetermined vertical dimension being greater than the first predetermined vertical dimension, said plurality of integrally interconnected sleeves including a plastic sheet forming web means interconnecting the upper extremities of the sleeves, the sleeves depending downwardly from the web means and arranged in a pattern permitting the web means to be disposed on the uppermost surface of the grid-like structure with the sleeves depending between the vertical wall means, each of the sleeves having walls tapering downwardly and inwardly from the uppermost extremity to the lowermost extremity thereof, the vertical dimension of the sleeve being substantially greater than said first predetermined vertical dimension and less than said second predetermined vertical dimension, whereby a plurality of said assemblies are stackable and nestable with each sleeve nesting in a sleeve below, the upper sleeve being spaced from the below sleeve so that said assemblies are freely denested from each other.

2. The assembly of claim 1, wherein the support tray is an integrally molded plastic member.

3. The assembly of claim 2, wherein the support tray is molded of a low density cellular plastic material.

4. The assembly of claim 1, wherein the support tray includes four intersecting, substantially flat sidewalls, the upper extremities of the sidewalls being coplanar with the uppermost surface of the grid-like structure.

5. The assembly of claim 1, wherein the sidewalls are inclined at an angle of approximately 15°

from the vertical.

6. The assembly of claim 1, further including a plurality of transplanting frames each of said plurality of frames disposed in an associated sleeve, the sleeves being open at their bottoms as well as their tops, each of said transplanting frames comprising a unitary molded member including an upper ring, a plurality of ribs depending from said ring and inclined downwardly and inwardly at the same angle of inclination as that of the sleeve walls, and an upwardly domed bottom wall connected to the lower end of said ribs, the upper sleeve, in nested assemblies, being spaced from the transplanting frame in the lower adjacent sleeve in said nested assemblies so that upon denesting of said assemblies said frames are not lifted from their associated sleeves.

7. The assembly of claim 1, wherein grid-like upper structure creates a plurality of apertures through which the sleeves may be inserted, each aperture located between a pair of adjacent longitudinal and lateral vertical wall means, being of a size large enough to receive a plurality of sleeves.

8. The assembly of claim 1, wherein each aperture is elongated and adapted to receive a plurality of sleeves in a single row.

9. The assembly of claim 1, wherein the sidewalls and upper structure of the support tray are integrally formed.
