5. A handling system according to claim 4, an insert part being fabricated of the same material as said flaps.

6. In a handling system, a container comprising a plurality of substantially equal length panels in side by side aligned relation with their adjacent side edges connected together and their end edges generally coplanar, said panels being swingable into a closed polygonal configuration to define a tube, a flap hingedly connected to the outer side edge of one outer panel and swingable into overlapping engagement with the other outer panel, a fastener extending through overlapping regions of said flap and other outer panel, a plurality of substantially identical tabs each hinged on one end edge of each panel at one end of said tube, said tabs tapering toward their free ends and being swingable generally normal to said panels with their free end portions overlying each other generally centrally of said tube to substantially close one tube end, and a fastener securing together said overlying free tab end portions, the remaining tab portions being free of each other, whereby said tube provides a soil container side wall and said tabs provide a soil container bottom wall with soil drainage between tabs.

7. A handling system according to claim 6, said panels, flap and tabs all being integrally fabricated of a stiff foldable plastic container sheet.

8. A handling system according to claim 7, said container sheet having folds defining hinged connections between adjacent panels and their respective tabs and flap.

9. A handling system according to claim 6, in combination with a tray for conformably receiving a plurality of said containers and comprising a lower support wall specifically configured for supporting engagement with the undersides of a predetermined number of said containers, said support wall being open for draining, and an upstanding surrounding wall extending circumferentially about said support wall in surrounding relation with said containers and upstanding from said support wall to a height no greater than that of said containers.

10. A handling system according to claim 9, said tray support and surrounding walls being integrally fabricated of a stiff foldable plastic tray sheet.

11. A handling system according to claim 10, said tray sheet comprising a central polygonal panel defining a support wall, a plurality of flaps extending integrally from respective sides of said central panel and hingedly connected to the latter by folds, said flaps being swingable upwardly relative to said central panel into end to end relation with each other to define said surrounding wall, and securing means releasably securing said flaps in said end to end relation.

12. A handling system according to claim 11, in combination with a stiffener board fabricated of less flexible material relative to that of said tubes and tray and removably engageable between each of said flaps and the adjacent containers to resist flap bowing.

13. In a handling system, a container comprising a plurality of substantially equal length panels in side by side aligned relation with their adjacent side edges connected together and their end edges generally coplanar, said panels being swingable into a closed polygonal configuration to define a tube, a tab hinged on one end edge of each panel at one end of said tube, said tabs being swingable generally normal to said panels with their free end portions overlying each other generally centrally of said tube, a fastener securing together said overlying free tab end portions, said tube providing a soil container side wall and said tabs providing a soil container bottom wall with drainage for the soil, and a tray for conformably receiving a plurality of said containers and comprising a lower support wall specifically configured for supporting engagement with the undersides of a predetermined number of said containers, said support wall being open for draining, and an upstanding surrounding wall extending circumferentially about said support wall in surrounding relation with said containers on said support wall, said tray support and surrounding walls being integrally fabricated of a stiff foldable plastic tray sheet, said tray sheet comprising a central polygonal panel defining a support wall, a plurality of flaps extending integrally from respective sides of said central panel and hingedly connected to the latter by folds, said flaps being swingable upwardly relative to said central panel into end to end relation with each other to define said surrounding wall, and securing means releasably securing said flaps in said end to end relation, said securing means comprising a pair of overlapping sheet portions, said sheet portions each having a pair of cuts defining therebetween a strip with the strips of said sheet portions in overlying relation, said strips being displaceable out of the planes of said overlying sheet portions, and an insert part having end enlargements and insertable into the space between said sheet portions and displaced strips with said end enlargements on opposite sides of said strips to retain the insert part in position.
