  • Patent number: 5520120
    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.

  • Patent number: 5289781
    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.

  • Patent number: 4850284
    Abstract: A pallet having a pallet deck which is formed from at least two pallet deck members, each of which has finger elements die-cut therein at each leg attachment point. The pallet legs are formed from tubular outer and inner leg elements, and are attached to both pallet deck members by stacking them atop one another and forcibly urging the finger elements on both pallet deck members within the annulus between the nested outer and inner leg elements. With this construction, the pallet deck is increased in strength since two pallet deck members are utilized and the pallet legs have greater strength and are less subject to damage from sideways forces parallel to the pallet applied to them since they are attached to the pallet by the finger elements die-cut in both of the pallet deck members.

  • Patent number: 4768704
    Abstract: A button fastener for use with a storage carton having a stud on one button member which is extended through the side wall of the storage carton. Another button member then is engaged with the stud so as to receive the stud in a bore in it and the two button members are pressed together to force the stud through the bore until locking shoulders formed by an enlarged head on the stud and the cavity about the bore lockingly engage with one another to affix the two button members together. A longitudinal slot in the stud and the enlarged head on it permits the enlarged head to be sufficiently compressed together to be extended into and through the bore, and to then expand to engage the locking shoulders. Conical walls of the enlarged head also assist in inserting the enlarged head into the bore. The enlarged head on the stud is contained substantially or completely within the cavity about the bore and is thereby prevented from puncturing or otherwise damaging the side walls of the storage carton.

  • Patent number: 4556167
    Abstract: An improved transfer storage carton having complimentary fastening means affixed to each of the respective end flaps and to at least one of the top flaps which are folded in overlapped relationship atop the open compartment of the carton in conventional fashion to effectively close and seal the carton. In this respect, it is preferred to use complimentary fasteners of the type sold under the trademark "VELCRO" by Velcro Corp. The complimentary fasteners are fixed to and carried by clips which are generally u-shaped in configuration. These clips are extended through slots formed in the end and top flaps to secure the fasteners to the flaps. In addition, one side flap is formed to expose the complimentary fasteners secured to the end flaps when the side flap is folded to overlie the end flaps so that the complimentary fastener affixed to the other one of the side flaps automatically lockingly engage to seal shut the carton.
