This invention relates to a cut and scored blank for forming a tray pallet, a preform formed by erecting the cut and scored blank, and the tray pallet formed from the blank and preform. The blank is formed of a planar body of sheet material cut and scored to form a substantially square main portion bounded by two cut edges and two score lines, each score line being parallel to an adjoining side cut edge of the body and being spaced from the adjoining side cut edge a predetermined distance which is a minor fraction of the length of the adjoining side cut edge, and the two score lines crossing adjacent one corner of the body to define with adjacent side cut edges of the body a square corner area. The body is cut along one of the score lines in such a manner that the square corner area is bounded by one score line and three cut side edges for facilitating folding of the body along the score lines and erection of the folded body into a preform in the form of a substantially square flat tray bounded along two sides of a raised lip and having a reinforced corner formed by lapped portions of the raised lip.

A preform for a pallet tray comprising; a first body of sheet material cut, scored, folded and erected into a substantially square flat tray having a main portion bounded along two contiguous sides by cut edges and two raised lip portions joined to the main portion along fold lines bounding two contiguous sides of said main portion, said lip portions having a height which is a minor fraction of the length of a side cut edge of said main portion and being joined at a contiguous corner by a lap portion joined to a contiguous one of said lip portions along a fold line and extending along the other of said lip portions, and means for securing together said lap portion and said other lip portion; a second body of sheet material cut, scored, folded and erected into a substantially square flat tray having a main portion bounded along two contiguous sides by cut edges and two raised lip portions joined to the main portion along fold lines bounding two contiguous sides of said main portion, said lip portions having a height which is a minor fraction of the length of a side cut edge of said main portion and being joined at a contiguous corner by a lap portion joined to a contiguous one of said lip portions along a fold line and extending along the other of said lip portions, and means for securing together said lap portion and said other lip portion; and means for securing together said first and second bodies of sheet material with said first and second body main portions overlying one another and said first and second body lip portions contiguous each to another, said means for securing together said first and second bodies joining said bodies at said lip portions so that said main portions are free of direct securement therebetween. A pallet tray comprising: first and second pallet preforms, each comprising a first body of sheet material cut, scored, folded and erected into a substantially square flat tray having a main portion bounded along two contiguous sides by cut edges and two raised lip portions joined to the main portion along fold lines bounding two contiguous sides of said main portion, said lip portions having a height which is a minor fraction of the length of a side cut edge of said main portion and being joined at a contiguous corner by a lap portion joined to a contiguous one of said lip portions along a fold line and extending along the other of said lip portions, and means for securing together said lap portion and said other lip portion; a second body of sheet material cut, scored, folded and erected into a substantially square flat tray having a main portion bounded along two contiguous sides by cut edges and two raised lip portions joined to the main portion along fold lines bounding two contiguous sides of said main portion, said lip portions having a height which is a minor fraction of the length of a side cut edge of said main portion and being joined at a contiguous corner by a lap portion joined to a contiguous one of said lip portions along a fold line and extending along the other of said lip portions, and means for securing together said lap portion and said other lip portion; and means for securing together said first and second bodies of sheet material with said first and second body main portions overlying one another nd said first and second body lip portions contiguous each to another, said means for securing together said first and second bodies joining said bodies at said lip portions so that said main portions are free of direct securement therebetween, said first and second pallet preforms being positioned with said main portions of said bodies thereof in interleaved, stacked array and with said lip portions of said bodies thereof defining portions of the boundaries of a generally rectangular load receiving area, said first and second pallet preforms being movable one relative to the other for adjusting the size of the load receiving area defined thereby. A bulk package adapted for handling by mechanized materials handling equipment and comprising a pallet tray comprising first and second pallet preforms, each comprising a first body of sheet material cut, scored, folded and erected into a substantially square flat tray having a main portion bounded along two contiguous sides by cut edges and two raised lip portions joined to the main portion along fold lines bounding two contiguous sides of said main portion, said lip portions having a height which is a minor fraction of the length of a side cut edge of said main portion and being joined at a contiguous corner by a lap portion joined to a contiguous one of said lip portions along a fold line and extending along the other of said lip portions, and means for securing together said lap portion and said other lip portion; a second body of sheet material cut, scored, folded and erected into a substantially square flat tray having a main portion bounded along two contiguous sides by cut edges and two raised lip portions joined to the main portion along fold lines bounding two contiguous sides of said main portion, said lip portions having a height which is a minor fraction of the length of a side cut edge of said main portion and being joined at a contiguous corner by a lap portion joined to a contiguous one of said lip portions along a fold line and extending along the other of said lip portions, and means for securing together said lap portion and said other lip portion; and means for securing together said first and second bodies of sheet material with said first and second body main portions overlying one another and said first and second body lip portions contiguous each to another, said means for securing together said first and second bodies joining said bodies at said lip portions so that said main portions are free of direct securement therebetween, said first and second pallet preforms being positioned with said main portions of said bodies thereof in interleaved, stacked array and with said lip portions of said bodies thereof defining portions of the boundaries of a generally rectangular load receiving area, said first and second pallet preforms being movable one relative to the other for adjusting the size of the load receiving area defined thereby, a quantity of sheet material load elements stacked on said pallet tray load receiving area, and wrap means encircling said load elements and said pallet tray for unifying said pallet tray and said load elements for handling.
