Abstract: A structurally self supporting shipping package adapted for use with mechanical handling equipment. The package may be embodied as a base or as a unitary carton formed by bending a single sheet of material such as fiberboard. The package includes a horizontal panel elevated by adjacent upward facing rectangular channels. Flaps formed at the ends of the channels engage rails formed along the sides of the panel, to transfer shear stress away from the channels and towards the rails. The rails may be assisted by flaps formed adjacent their connection to the panel. The package may be further strengthened if certain portions are formed by placing multiple thicknesses of material adjacent each other. The structurally self-supporting package allows accommodation of a variety of oddly shaped items. Package assembly may be expedited if the rails are formed in sections.

When folded and erected, a wedge-shaped container having an inner liner forming a false bottom is produced. A plurality of scored fold sites permit the depth of the false bottom to be varied as desired. Changing the depth of the false bottom effectively changes the size of the container. This may be done by the manufacturer or by the consumer.

Abstract: A package blank is made from a single sheet having at least surface layers of heat-sealable material. The blank sheet comprises first and second rectangular panels foldably formed on opposite sides of a backstrip. The first and second panels have first and second pairs of foldable side flaps, respectively, extending from their opposite sides, and the backstrip has a pair of foldable back flaps extending from its opposite ends. The first side flap pair and the back flap pair have sloping edges located adjacent each other for forming at least partly overlapping seams when the blank is folded up into a generally boxlike, open-front package. The overlapping seams serve to prevent the intrusion into the package of heated air used for fusing the second side flap pair onto the first side flap pair and the back flap pair.

Abstract: A box assembly comprising a series of three corner connected boxes is formed from a unitary blank of sheet material. The unitary blank is suitably cut and scored to include along the length thereof twelve body panels, two pairs of tabs, each pair spaced apart by an even number of body panels, and a flap on the end of the blank. In addition, closing flaps are suitably cut and scored on the tops and bottoms of selected ones of the body panels for use in closing off the openings on the tops and bottoms of the individual boxes of the assembly. To fabricate the box assembly from the blank, the tabs of each pair of tabs are folded and glued back on themselves to form a joining flap. An adhesive is then placed on the surfaces of each of the joining flaps and the end flap. The blank is then folded over on itself such that six of the body panels on the blank are superimposed over the remaining six.

Abstract: A blank is folded to form a box by pressing it into a jig. End and side panels of the blank, along with supplemental panels at the corners, are lifted relative to a floor panel by folding surfaces of the jig. The side panels are lifted first and supplemental end panels are thus positioned inside the end panels. The blank may also include supplemental side panels that are folded outwardly and backwardly by corner guides of the jig.

Abstract: A cover sheet is disposed over a recess in a work table. A folding apparatus, including an edge folder and edge erector is disposed over the recess and lowered until the edge erector is in the recess. The edge erector includes horizontally movable plates which are moved outwardly against the edges of the recess to erect the marginal edges of the sheet. The edge folder has downwardly depending, horizontally moving members. The edge folder is lowered until the members touch the work table after which the members are moved inwardly to fold the erected marginal edges of the sheet horizontally over the plates. The plates are then withdrawn while the edge folder members are maintained in contact with the folded marginal edges, and high frequency heat applied to weld the folded marginal edges to the sheet. After the welding is completed the edge erector and edge folder are raised to their initial position and the members are returned to their outward positions.
