  • Patent number: 5427240
    Abstract: A shipping box for plants set with soil in pots, in which a plurality of holder panels are positioned in the box in spaced relation. Each panel is formed with a plurality of pairs of entry slots extending vertically upwardly from the bottom of the panel. The entry slots terminate at their upper ends in retaining slots adapted to receive elastic, resilient retainer bands which when expanded are adapted to extend around and thus constrict a potted plant and resiliently bias the plant toward the panel. The plant is thus retained in position during shipping, and its spilling of soil is prevented in the event the box is tipped or tilted.
