The invention claimed is: 1. An open top box-shaped container, comprising: a pair of confronting end walls tiltably pivoted and coupled with first and second bearing pins to a bottom wall, wherein said end walls are pivoted at the bottom wall so as to be folded in contact with a top of the bottom wall, wherein an end stopping protrusion is formed on a pivoting side edge of the end walls, a pair of side walls are tiltably pivoted and coupled with third and fourth bearing pins to the bottom wall, wherein a side stopping protrusion is formed on a pivoting side edge of the side walls, said first and second bearing pins being molded at opposing corners of said end walls and said third and fourth bearing pins being molded at opposing corners of said side walls and projecting into corresponding holes disposed in said bottom wall such that end walls are folded in contact with said top of said bottom wall and said side walls are folded in contact with a top of said end walls, and said end stopping protrusion and side stopping protrusion being a sectional U shape having a horizontal leading end, such that when said side walls are in an erect position an end stopping groove and a side stopping groove having a horizontal receiving portion on said bottom wall mates with each said side stopping protrusion to form an erect side stopping structure so that substantially no load is applied to the bearing pins when a load is applied in the downward direction to erect said end walls and said side walls. 2. The container according to claim 1, wherein a pivoting position between the bottom wall and the side wall is formed inside of the erect side stopping structure. 3. The container according to claim 1, wherein a pivoting position between the bottom wall and the end wall is formed inside of the erect side stopping structure. 4. The container according to claim 1, further comprising a second erect side stopping structure comprised of a side stopping receiving groove at a side portion of the side stopping groove, and a side stopping pawl at a side of the side stopping protrusion. 5. The container according to claim 1, further comprising a second erect end stopping structure comprised of an end stopping receiving groove at a side portion of the end stopping groove, and an end stopping pawl at a side of the end stopping protrusion. 6. The container of claim 1, wherein the bottom wall, side walls, and end walls are a hollow double wall structure.
