Abstract: In a so-called strapless bin erected on a pallet, normally open self locking clips are compressed during bin erection by the on fork bin sides to lock and hold adjacent right angle bin sides in the erected disposition. The two off pallet bin sides have peripheral self locking corner irons, with two such self locking corner irons being placed on either vertical side of the off pallet side with vertical inset returns at their extremity. There inset returns key to corresponding routed grooves formed exteriorly at the side vertical edges of the adjoining on pallet bin sides. An internally mounted normally open side supporting clip is placed on the interior of the off pallet side at a sufficient interval to snugly capture the on pallet exteriorly grooved side into the self locking corner irons of the off pallet side. When the on pallet side seats at the routed grooves to the inset return of the off pallet side, the spring clip opens, snugly locking the two bin sides at right angles in an erected configuration.

Abstract: A paste bin is disclosed in which the combination of self locking corner irons enable both the elimination of straps utilized to hold the containers together as well as the relatively complex pre-strapping assembly. Accordingly, self locking corner irons are placed on the off pallet sides of the container with two such self locking corner irons being on either vertical side of the off pallet side of the bin. Each of these corner irons consists of eleven gauge (1/8 inch) steel strips bent at 90.degree. to form two longitudinally extending side capturing edges. The vertical dimension of the self locking corner irons is slightly less than all of the height of the sides. On the off pallet side, the edge of the corner irons includes punched intermittent annular inwardly protruding male flanges. These inwardly protruding annular male flange are for receiving the heads of flat head machine screws for permanently fastening the self locking corner irons to the off pallet sides.

Abstract: A bulk container which is disassemblable such that the interchangeable wall panels and the locking clips which connect the wall panels fit flatly into the flanged base assembly of the container. A base assembly provided with flanged sides holds the disasembled rectangular side panels. Each side panel is provided with a miter strip adjacent each side edge which extends below the lower edge in a leg. The leg supports the panel above the flange of the base assembly. Adjacent the miter strip at each side of the panel is a short slot. Locking clips engage a pair of panels at each corner by engaging the slots. The size reduction afforded by the disassembled condition of the container provides for more efficient shipping and transportation of the containers. Interchangeable parts reduce overall costs and the time required for assembly and disassembly.
