  • Patent number: 4230227
    Abstract: A folding container construction has a wooden reinforcing framework which is attached to the side (74, 75) and end walls (98, 99) of the box. The side walls (74, 75) of the box are provided with vertical struts (82, 84, 86) disposed at the peripheral edges of the walls and a single, horizontal brace (79, 80) disposed adjacent to the top of the wall. At least one horizontal reinforcing member (104, 105) is provided on each end wall of the box with the horizontal members being received by slots defined by the struts on the side walls and the horizontal brace to maintain the box configuration. The end walls (98, 99) are maintained on the base (60) of the container by the bottom surfaces of the vertical struts which seat against a bottom flap (92, 93) on the end walls when the box is constructed. In this way, the need for separately attaching the end walls to the container base is eliminated.
