Material transport cage and methods of using the same

A method of using a stackable apparatus for transporting at least one cylinder, comprising:

• providing a plurality of vertically or horizontally stackable hollow containers (15), each container having the shape of six rectangular sides, each adjacent side forming a right angle where the adjacent sides join, comprising:
• first and second lateral sides (18, 21),
• wherein a top portion (38) of the first lateral side (18) comprises an open slot groove (130) and a bottom portion (50) of the first lateral side (18) comprises wheels (118),
• wherein a top portion (41) of the second lateral side (21) comprises an open slot groove (131) and a bottom portion (53) of the second lateral side comprises an open slot groove (135);
• a front side (24),
• wherein a top portion (44) of the front side (24) comprises an open slot groove (89) and a bottom portion (56) of the front side (24) comprises an open slot groove (85) and an open slot groove (88) in the front proximal and front distal edges (65, 71) of a wall (62) of the container (15);
• a rear side (27);
• wherein a top portion (47) of the rear side (27) comprises an open slot groove (90) and a bottom portion (59) of the rear side (27) comprises an open slot groove (86) in the rear proximal edge (68) and an open slot groove (87) in the rear distal edge 74) of a wall (62) of the container (15);
• and
• a bottom side (33),
• wherein the bottom side (33) comprises a recessed groove (34) that runs along the perimeter of the bottom side (33);
• an open top (30),
• wherein the wheels (118) of one container are insertable into the open slot grooves (130, 131) in the top portion (38) of the first lateral side (18) and the top portion (41) of the second lateral side (21) of another container to achieve secure vertical stacking of the two containers, or
• wherein the wheels (118) of one container are insertable into the open slot grooves (135) in the bottom portion (53) of the second lateral side (21) to achieve secure horizontal stacking of the two containers,
• wherein the first and second lateral sides, the front side, and the rear side run along a longitudinal axis of the container,
• wherein the bottom side (33) and an opening in the top are in a plane orthogonal to the longitudinal axis,
• wherein adjacent sides of each container are operably coupled to form the wall (62) of the container,
• wherein the wall includes front and rear proximal edges and front and rear distal edges,
• wherein a proximal edge is defined as being closer to a longitudinal axis running along the center of a vehicle (83), by which the container is transported, than a distal edge, and
• wherein the front and rear proximal edges are formed by coupling a first lateral side to the front and rear sides, respectively, and the front and rear distal edges are formed by coupling the second lateral side to the front and rear sides, respectively,
• providing at least one cylinder having valve extending from a neck end of the cylinder;
• inserting the at least one cylinder through the open top of one of said containers, so a length of the cylinder and the valve do not exceed a depth of a cavity inside the container;
• extending said cavity at least about 17 to 19 inches from the top portions of the first and second lateral sides, from the top portion of the front side, and from the top portion of the rear side of the wall of the container to the bottom portions of the first and second lateral sides, to the bottom portion of the front side, and to the bottom portion of the rear side of the wall of the container,
• wherein a length between each adjacent edge of the container is at least about 12 inches;
• placing said container on a seat of a vehicle (83), so that the bottom side of the container (33) rests on a first surface of the seat, and
• extending a seat belt (103) around the container (15), so that a container centered shoulder portion (106) of the seat belt extends diagonally from a wall of the vehicle (83) above the container through the open slot groove (89) in the top portion (44) of the front side (24) of the container and a waist portion (109) extends through the open slot grooves (85, 88) in the front proximal edge (65) and the front distal edge (71) of the wall (62) of the container (15) so that the container (15) is secured on the seat (115) of the vehicle (83);
• vertically stacking the plurality of hollow containers, such that the recessed groove (34) that runs along the perimeter of the bottom side (33) is securely inserted into the top (30) of another container and wheels (118) insert into open slot grooves (130, 131) into the top portions (38, 41) of the first lateral side (18) and second lateral side (21) of the wall (62) of the container;
• or
• horizontally stacking the plurality of hollow containers, such that wheels (118) insert into open slot grooves (135) into the bottom portion (53) of the first lateral side (18) and second lateral side (21) of the wall (62) of the container.
