  • Patent number: 5517927
    Abstract: A container kit including a rectangular base ring with mounting structure on opposite sides of a base ring for engaging battens on opposite sides of a pallet. There is a first pair of rectangular side panels, each with a bottom adapted to engage in channels between upper base ring flanges and lower base ring flanges, and a second pair of like panels, each with a bottom adapted for engaging between upper base ring flanges and lower base ring flanges. The second panel pair is disposed between the first panel pair, thereby preventing the disconnection of all panels from channels between the upper and lower base ring flanges, with latches for connecting adjacent sides of the panels of the first and second panels.
