Abstract
An improved collapsible sidewall structure for a stackable bin having a sidewall which is of a two-ply construction defined by inner and outer layers, each being extruded plastic layers having inner and outer sheets joined by transversely extending ribs so as to define elongated flutes or channels, with one of the inner and outer layers having the flutes projecting horizontally, and the other layer preferably having the flutes projecting vertically. The horizontally fluted layer also defines a corner hinge arrangement of the sidewall structure. The horizontally fluted layer, adjacent the free edge of the vertically fluted layer, is provided with an undercut slot projecting vertically thereof and opening inwardly for communication with the interface between the inner and outer layers. This slot has a vertically elongated reinforcing bar adhesively secured therein.
