Abstract
Abstract A collapsible insert for a seedling tray formed integrally from a single sheet of plastic material. The insert, in the folded position, has a plurality of adjacent parallel U-shaped channels each having a base with integrally folded sides. A plurality of integrally formed longitudinally spaced transverse dividers extend across each channel to form compartments therebetween. The sides of adjacent channels have the free longitudinal edge thereof integrally united for accordion folding. Pull tabs are provided on the edges of the farthest spaced sides. Upon removal of the folded insert from the tray and manual application of tension to the tabs, the sides of each channel fold open to become planar with the base and the dividers rotate with the sides about the folds, thus collapsing the compartments in each channel for enabling easy removal of seedlings.

Claim 1
Independent Claim
354 words
An insert for a seedling tray comprising: a. a plurality of base portions of elongated configuration with each base portion having spaced opposite longitudinal base margins; b. a plurality of side portions of generally elongated configuration with each of said base margins having a longitudinal margin of one of said side portions integrally and hingedly united therewith for movement of said side portion between an unfolded position parallel to and a folded position at generally right angles to said base portion, in which folded position each of said base portions with its respectively integral side portions forms a generally U-shaped channel, and the adjacent side portions of respectively adjacent base portions have the free longitudinal margins of saiD side portions integrally and hingedly united such that said adjacent side portions are folded in substantially parallel back-to-back arrangement in the said folded position; and c. a plurality of openable divider means formed integrally with said side portions and extending substantially perpendicularly therefrom in longitudinally spaced arrangement, such that when the side portions are in said folded position, said divider means provide spaced transverse barriers between the base and sides of each of said U-shaped channel for forming a plurality of cavities therebetween and in the said open position, the said side portions and base portions are in integral co-planar arrangement with each of said divider means completely opened and substantially perpendicularly therefrom wherein said divider means includes first portions extending inwardly of the channel from each of said side portions with said first portions arranged in pairs on opposite sides of each of said channels with the individual members of each of said pairs disposed at a common longitudinal station with portions of the margins of the members of each pair in mutual contact at midchannel; and second portions formed integrally with each of said base portions extending substantially perpendicularly therefrom in longitudinally spaced parallel relationship at longitudinal stations corresponding with each pair of said first portions, with each of said second portions having portions of the margins thereof contacting portions of the margin of each member of the corresponding pair of said first portions.
Claim 2
Dependent Claim
354 words
An insert for a seedling tray comprising: a. a plurality of base portions of elongated configuration with each base portion having spaced opposite longitudinal base margins; b. a plurality of side portions of generally elongated configuration with each of said base margins having a longitudinal margin of one of said side portions integrally and hingedly united therewith for movement of said side portion between an unfolded position parallel to and a folded position at generally right angles to said base portion, in which folded position each of said base portions with its respectively integral side portions forms a generally U-shaped channel, and the adjacent side portions of respectively adjacent base portions have the free longitudinal margins of saiD side portions integrally and hingedly united such that said adjacent side portions are folded in substantially parallel back-to-back arrangement in the said folded position; and c. a plurality of openable divider means formed integrally with said side portions and extending substantially perpendicularly therefrom in longitudinally spaced arrangement, such that when the side portions are in said folded position, said divider means provide spaced transverse barriers between the base and sides of each of said U-shaped channel for forming a plurality of cavities therebetween and in the said open position, the said side portions and base portions are in integral co-planar arrangement with each of said divider means completely opened and substantially perpendicularly therefrom wherein said divider means includes first portions extending inwardly of the channel from each of said side portions with said first portions arranged in pairs on opposite sides of each of said channels with the individual members of each of said pairs disposed at a common longitudinal station with portions of the margins of the members of each pair in mutual contact at midchannel; and second portions formed integrally with each of said base portions extending substantially perpendicularly therefrom in longitudinally spaced parallel relationship at longitudinal stations corresponding with each pair of said first portions, with each of said second portions having portions of the margins thereof contacting portions of the margin of each member of the corresponding pair of said first portions.
Claim 3
Dependent Claim
64 words
The insert defined in claim 1, wherein the portions of the margins of each of said first portions in mutual contact at mid-channel form a parting line substantially perpendicular to the corresponding base portion, and each of said second portions has the portions of the margins thereof contacting said first portions forming a parting line making an oblique angle to the corresponding base portion.
Claim 4
Dependent Claim
51 words
The insert defined in claim 2, wherein each of said second portions has a substantially planar triangular configuration with the base of said triangle formed integral with the corresponding base portion of the channel and with the apex of said triangle coincident with the said parting line perpendicular to said base.
