  • Patent number: 5819941
    Abstract: A pallet is disclosed for housing plants during their growth, transport and display. In the preferred embodiment, the pallet has a generally rectangular central deck; four sides or rims that border that deck; and two rows of complementary W-shaped legs along opposite sides. The unique structures of these leg rows allow for: secure nesting of multiple pallets when empty; secure stacking of multiple pallets during transportation; and stacking in multiple configuration for display on store floors. Not only are the displays quick to assemble, they also provide easy access for maintenance of the housed plants by employees (e.g., watering), plus inspection and removal of the plants by perspective customers.
