Open-walled pack

A pack comprising:

• a unitary blank folded into a rectangular cuboid, the rectangular cuboid defining:
• a bottom;
• a top parallel to and opposite of the bottom;
• and
• four walls perpendicular to and disposed between the top and the bottom, the four walls each formed of a respective wall panel, the wall panels including a first wall panel, a second wall panel, a third wall panel, and a fourth wall panel, the first wall panel opposite of the third wall panel, and the second wall panel opposite of the fourth wall panel,
• wherein respective wall folds form a boundary between the first wall panel and the second wall panel, between the second wall panel and the third wall panel, and between the first wall panel and the fourth wall panel, wherein a fourth wall fold forms a boundary between the third wall panel and a tube-forming flap, the tube-forming flap fastened to the fourth wall panel,
• wherein the bottom is formed of a plurality of bottom flaps extending from respective wall panels, at least two of the bottom flaps fastened together,
• wherein the top is formed of a first top flap extending from the third wall panel and a second top flap extending from the first wall panel, wherein the first top flap is floating, and the second top flap is disposed over at least a portion of the first top flap, the second top flap including an intermediate panel and a distal panel having a mid-flap fold therebetween, the intermediate panel disposed over at least a portion of the first top flap and the distal panel disposed over a portion of, and fastened to, the third wall panel.

A method of erecting a pack, the method comprising:

• forming a rectangular tube having four perpendicular walls and a bottom;
• placing items in the rectangular tube;
• folding a first top flap inward, such that the first top flap is perpendicular to a third wall of the tube from which the first top flap extends;
• folding a second top flap inward, such that the second top flap is parallel to and disposed over at least a portion of the first top flap;
• folding a distal end of the second top flap, which extends beyond the first top flap, such that the distal end of the second top flap is parallel to the third wall of the tube;
• and
• fastening the distal end of the second top flap to the third wall of the tube.
