A collapsible, reinforced, four sided container attached to a rigid base comprising:

• a first and second side wall comprising a first pair of opposed reinforced rectangular side walls having an inner and outer face with reinforcing therebetween, each of said side walls being hingedly connected to a bottom flap along the bottom of said reinforced side wall, the bottom flap connected to said first side wall having an additional fold score parallel to and spaced from said hinge connection and the bottom flap connected to said second side wall having a fold score parallel to and spaced from said hinge connection;
• a third and fourth side wall comprising a second pair of opposed reinforced rectangular side walls having an inner and outer face with reinforcing therebetween, each of said side walls being hingedly connected to a separate bottom flap, each of said separate bottom flaps having a fold score parallel to and spaced from said hinge connection of each of said third and fourth side walls, the spacing of said fold scores providing overlaying of the sides to collapse the side walls flatly;
• each of said first pair of reinforced side walls having fastening means along each edge adjacent and at right angle to said hinge connection and each of said second pair of reinforced side walls having a mating fastening means along each edge adjacent and at a right angle to said hinge connection, said fastening means and mating means engageable with each other when the reinforced side walls are perpendicular to said bottom flaps;
• and the bottom flaps of said first pair of opposed side walls attached to a rigid base inwardly from the sides enclosed by said second pair of side walls, the bottom flap of said second pair of side walls slidable between the bottom flaps of the first opposed sides and the rigid base.
