Load tray and method for unitizing a palletized load
First Claim
1. A load tray comprisinga central base having four sides and four rounded corners and having a length and a width,four flaps hingedly connected to said central base, two of said flaps being connected to said central base along its width but having a width that is less than the width of said central base and the other two of said flaps being connected to said central base along its length but having a width that is less than the length of said central base andat least three flap positioners connected to three of said flaps and operable to releasably maintain said flaps in a position where they form angles with said central base of between ninety and one hundred thirty five degrees.

Abstract
A new load tray especially well suited for use under loads on pallets is disclosed. The tray has a central load supporting base and as many as four flaps hingedly connected to the base. The tray includes flap supports for supporting the flaps and releasably maintaining them at a 90 to 135 degree angle relative to the base. The tray is designed so that it may be positioned on a pallet and have a load placed on it so that the flaps remain in an upstanding position so that when the load is wrapped, the flaps are held captive against the load.

4. A method for unitizing a pallet load, said method comprising the steps of
providing a pallet having two opposed ends, two opposed sides and an upper load supporting surface, providing a load tray comprising a central base having four sides and four rounded corners and having a length and a width, at least two flaps hingedly connected to said central base, two of said at least two flaps being connected to said central base along its width but having a width that is less than the width of said central base and at least two flap positioners connected to said at least two flaps and operable to releasably maintain said at least two flaps in a position where they form angles with said central base of between ninety and one hundred thirty five degrees, positioning said central base of said load tray on said upper load supporting surface of said pallet with said at least two flaps releasably maintained in positions where they extend outwardly away from said central base and they extend upwardly away from said pallet, positioning a load comprising a plurality of packages on said central base, between said at least two flaps so that free ends of said at least two flaps are spaced away from the packages which make up the load, and wrapping the load, the load tray and the pallet with wrapping material so that the wrapping material engages the free ends of said at least two flaps and draws those ends up tight against the load.
