ABSTRACT:
The field of invention relates to a corrugated cardboard pallet of the type generally formed by a pair or more of pallet decks which are stacked atop one another, each of which has finger elements die cut therein radiating outwardly from a central circle and terminating on a circular score line of substantially the same diameter as the inner diameter of one of the leg elements. The die cut lines for the fingers radiate tangentially outwardly to create a substantially spiral pattern. The improvement of the present invention is the provision of stress relief circular punch-out sections positioned adjacent the circular score line and having a diametric dimension extending inwardly from the score line in the direction of the central circle and laterally on each side of each of the die cut lines. The stress relief punch-out sections function to relieve the stress caused when the finger elements are folded downwardly in order to accept the attachment of the pallet legs to the pallet deck.
