Abstract: A moisture-resistant expendable shipping container of corrugated paperboard for storing and shipping plants. The container may be stacked on top of other containers and may be palletized. It includes at least one shallow tray that forms at least a bottom for the container, and a pair of substantially identical partition members arranged in substantial mirror image relationship to one another in the tray. The partition members are formed of plural angularly interconnected flat panels resting on their edge in the tray, and define a transverse wall extending across a mid-portion of the tray and a peripheral wall extending at least partially to around the periphery of the tray. The partition members provide support for multiple containers stacked on top of one another, and at least partially enclose the plants.

Abstract: A lightweight, very strong form of a concrete beam includes a plurality of U-shaped brace members having vertical, lightweight steel deck sheets secured to the uprights thereof, a strippable, non-stick, plastic liner for contacting the concrete of the beam and a rigid foamed plastic filling the space between the liner and the steel sheets, so that it supports the weight of the concrete poured onto the strippable, plastic liner. A column form is arranged to mate with the beam form, and the beam form may be used to mate with flying deck forms producing an integral, combined column, beam and deck structure. The forms are arranged for easily joining short beam sections to make long beam forms, and to join columns and floor decks with a smooth joint requiring no finishing. The strength of the beam forms reduces the quantity of supports necessary to hold the weight of the forms and poured concrete, and their configuration provides easy and quick stripping of the forms from the set concrete.
