  • Patent number: 5772026
    Abstract: A multi-deck container having a bottom pallet configured with support members for receiving and supporting a lawn and garden tractor on the bottom pallet, whereby the tractor is restrained from movement relative to the bottom pallet. A corrugated paperboard body defines two opposing side walls and two opposing end walls. The corrugated paperboard body attaches at a lower portion to the bottom pallet. A plurality of cleats attach to the walls and extend from a lower portion to an upper portion thereof. The distal ends of the cleats in the upper portion of the corrugated paperboard body support a top pallet which has support members for receiving and supporting a second lawn and garden tractor thereon whereby the second tractor is restrained from movement relative to the top pallet. The pair of lawn and garden tractors are held in the multi-deck container for packing and shipping the tractors from a manufacturer to a sales center.

  • Patent number: 5275279
    Abstract: A container for storing and shipping outboard motors horizontally. The motor attaches to an H-frame by screwing the bolts on the stern bracket to a cross bar. Vertical cleats attach to the sides of a corrugated paperboard carton, and the cleats guide the H-frame into the carton. A hold-down pad formed by folding a blank of corrugated paperboard having scores defining a plurality of panels attaches to an end wall and engages the skeg of the motor to restrict pivotable movement of the motor during shipping and handling.
