Abstract: A stabilizer box has a number of interconnected panels which automatically articulate to form a bottom which converts the box from a flat and knock-down shape into a cubical configuration. The box opens and the bottom locks in place simply by pushing on the opposite ends of the flat, knock-down shape. The top of the box is formed by four interconnected wedge or somewhat pie-shaped panels which snap down into the plane of the top of the cube responsive to a slight pressure of the thumb upon articulation panels. Each of the four wedge or somewhat pie-shaped top panels has a quarter circle, arcuate cutout, at the tip of the wedge or somewhat pie-shaped panels. The cutouts come together to form a variable circular opening when the top is set up.
