- 8. A collapsible pallet box comprising: four side walls, each side wall overlapping the end of one adjacent side wall and overlapped by the end of the other adjacent side wall when said box is erected; a first and a second set of four aligned horizontal cleats secured to the exterior of said side walls, said first set positioned adjacent to the top of said side walls and said second set positioned adjacent to the bottom of said side walls, said cleats each extending the width of said side walls and over the ends of said lapped adjacent side walls, the length of each cleat being equal to the internal horizontal dimension of the box along the side wall to which it is attached plus twice the thickness of said side walls, and said cleats having aligned longitudinal channels; and an endless strap for each set of cleats, said strap slidably located in said channels and passing around the periphery of said box, said strap fitting tightly in said channels when said box is in erected and collapsed positions.
- 9. The pallet box as defined in claim 8 wherein one of each adjacent pair of inside vertical edges of said side walls is rounded to facilitate overlapping when said box is set up.
- 10. The pallet box as defined in claim 9 wherein said strap is retained in said channels by overlying staples.
- 11. The pallet box as defined in claim 9 wherein the ends of said cleats are inwardly beveled. .Iadd. 12. A collapsible pallet container comprising four side walls each formed of vertically extending slots, said side walls having inner and outer faces and first and second opposed vertical edges; the vertical edges of the adjacent side walls being in lapped relationship when the container is in the erected position with said first vertical edge of each side wall in end abutting relation with the inner face of an adjacent side wall adjacent the second vertical edge of said adjacent side wall, two sets of four aligned horizontal cleats secured to the outer faces of said side walls said cleats each having a length which is equal to the length of the side wall to which it is secured plus the approximate thickness of the side wall slats, one of said sets being positioned adjacent the top of said side wall and the other of said sets being positioned adjacent the bottom of said side walls with the end of one of the two adjacent cleats at each corner of said container being aligned with the adjacent second vertical edge of the side wall to which said cleat is attached and with the end of the other adjacent cleat at said corner extending beyond the first vertical edge of the side wall to which said cleat is attached a distance approximately equal to the thickness of said slats, whereby, when the container is in the erected position, the second edge of one of the two adjacent slats at each corner overlaps the first edge of the other adjacent slat with its inner face engaged with the first vertical edge of said adjacent slat and the adjacent ends of the cleats in each of said sets are contiguous but non-overlapping and, when the container is collapsed, alternate pairs of adjacent cleat ends in each of said sets come into end abutting relationship, a pair of endless flexible metal straps, each extending around said container parallel to and overlying one of said sets of cleats, the circumference of said straps being such that said straps fit substantially tightly around said container in both the erected and collapsed positions, said cleats including means for laterally retaining said straps on the cleats while permitting longitudinal movement thereof as the container is moved between the erected and collapsed positions. .Iaddend..Iadd. 13. A container as defined in claim 12 wherein said cleats are butt-ended and wherein said slats have a thickness not exceeding approximately 0.4 times the thickness of said cleats. .Iaddend.

The present invention relates to collapsible containers, and more specifically to an improved collapsible pallet box.
A pallet box is used in conjunction with a pallet to transport loads with a fork lift. The box comprises four side walls which fit on top of the pallet in order to retain bulk materials. A disadvantage with pallet boxes presently available is that they take up a great deal of space in storage. Although some currently available boxes may be collapsed, this is a time-consuming procedure, often involving partial disassembly. Designs have been produced which do not require partial disassembly to collapse the box, but these boxes are generally complicated and expensive to produce.
Generally, the present invention relates to a collapsible pallet box of simple design which is relatively inexpensive to produce. The box is of generally rectangular configuration in plan when erected, and has four side walls as is conventional in the art. The side walls are each in lapped relationship with the ends of the adjacent side walls when the box is erected. Each of the side walls has a horizontal cleat secured to its exterior, so that there is at least one set of four such cleats which are aligned and extend the width of the side walls. Each cleat also extends over the ends of the lapped adjacent side walls so that, where necessary, it will extend beyond the end of the side wall to which it is attached a distance equal to the thickness of the adjacent side wall. Of course, where the side wall to which the cleat is attached overlaps the end of the adjacent side wall, this extension is not necessary. The cleats have aligned longitudinal channels, and an endless strap is slidably located in the channels, passing around the periphery of the box. The cleats are formed so that the strap will fit tightly around the box when it is in the erected position and also when the box is in the collapsed position.
