Claim:
An apparatus comprising: a box portion including: a left side, a right side, a front side, a rear side, and a bottom; wherein each of the left, the right, the front, and the rear sides are connected to the bottom so that each is configured to be foldable with respect to the bottom, from an orientation parallel to the bottom to an orientation substantially perpendicular to the bottom; and further comprising a device connected to the bottom, the device including an inner peripheral wall which extends, for a height of the inner wall, substantially perpendicularly from the bottom; wherein the inner peripheral wall is substantially in the shape of a loop and has a width and a length, substantially perpendicular to the height of the device, wherein the width and the length of the inner peripheral wall are slightly less than a width and a length, respectively, of an inner chamber defined by top edges of the left, the right, the front, and the rear sides, when the box portion is in an upright state such that the left, the right, the front, and the rear sides are substantially perpendicular to the bottom, so that the inner peripheral wall is configured to fit snugly into an inner chamber of a second apparatus which is identical to the apparatus, and wherein the inner chamber of the second apparatus is identical to the inner chamber of the apparatus; wherein the left side of the box portion includes first and second outer sections, and a central section, wherein the first outer section of the left side is connected to a first end of the central section of the left side and the second outer section of the left side is connected to a second end of the central section of the left side, which opposes the first end of the central section of the left side; wherein the right side of the box portion includes first and second outer sections, and a central section, wherein the first outer section of the right side is connected to a first end of the central section of the right side and the second outer section of the right side is connected to a second end of the central section of the right side, which opposes the first end of the central section of the right side; wherein each of the first and the second outer sections of the left side is connected to the central section of the left side so that each is configured to be foldable with respect to the central section of the left side, from an orientation parallel to the central section of the left side to an orientation substantially perpendicular to the central section of the left side; and wherein each of the first and the second outer sections of the right side is connected to the central section of the right side so that each is configured to be foldable with respect to the central section of the right side, from an orientation parallel to the central section of the right side to an orientation substantially perpendicular to the central section of the right side.
