Abstract: A container which includes a plurality of elongated frame members each having an elongated channel and an elongated recess therein and a plurality of coupling members removably engagable with ends of the frame members. A plurality of panels is removably engagable with the elongated channels in the frame members and each of the panels has an elongated recess around a perimeter thereof which, together with the elongated recess in each of the frame members, forms an elongated slot. A lock element is removably insertable into the slots formed by the panel recesses and frame member recesses, when the panels are in engagement with the channels, to lock the frame members, panels and coupling members into a substantially rigid assembly.
