Abstract
There is disclosed an improved corrugated pallet having pallet legs attached at various points of attachment. 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 leg assembly is of the type formed by an outer leg, and an inner leg, with the radiating die cut fingers nested between the annulus created between the outer and inner leg and adhesively secured to the legs. The improvement consists of die cutting a series of linearly aligned perforations along the length of each finger, such that when the adhesive is applied to the outer and inner surfaces of the fingers, the adhesive is permitted to permeate the inner confines of the corrugated material forming the fingers thereby increasing the surface area of adhesive for securing the finger elements to …
