  • Patent number: 5131708
    Abstract: A handling system configured for use with a receptacle having a bottom, sides and a flange. The system has a bail for supporting the receptacle, a guide for guiding the bail, and a stop structure for retaining the bail within the guide. The bail is freely movable within the guide and is movable between two positions. In the first position, the bail extends above the flange in a carrying position. In the second position, the bail extends below the flange in a stowed position. The bail is preferably comprised of two substantially parallel legs connected by a base. The two legs each include a bias structure preferably in the form of a deviation by which the base of the bail is held against an adjacent wall of the receptacle when the bail is in the stowed position. The legs of the bail pass through guide openings in the flange of the receptacle and attach to the stop structure. In the stowed position, the stop structure substantially covers the guide openings in the flange.

  • Patent number: 5035327
    Abstract: A receptacle adaptable for nested stacking which has a bottom and walls which cooperate to form an open-topped well having rounded corners defined by a first radius. The receptacle includes a plurality of stop structures for limiting depth of insertion of adjacent receptacles in a nested orientation, which stop structures are preferably located at the corners of the well and comprise an integrally formed depression and an associated shelf in each corner.The shelf is generally planar and generally horizontal and has a boundary adjacent the well which is defined by a second radius, larger than the first radius which defines the corners.The depression has a first portion and a second portion. The first portion preferably depends outwardly of the well substantially from the boundary of the shelf and extends beyond a vertical line intersecting the boundary. The first portion is pitched outward of the vertical line from the boundary of the shelf.
