Multifunctional mobile storage and delivery system

A collapsible container assembly, comprising:

• a base panel;
• interchangeable side panels removably attached to the base panel, the side panels interconnected with each other and form a substantially fluid-tight seal with the base panel when the side panels are in a substantially upright, closed position, the side panels and base panels defining an internal volume when the side panels are in the closed position, at least one of the side panels being movable between the closed position and a lowered, open position with a bottom edge of the respective side panel being in engagement with the base panel when in the first, lowered position to form a ramp for access into the internal volume of the container assembly;
• a top panel removably attached to the side panels and forming a substantially fluid-tight seal when the side panels are in the closed position, the top panel being combined with the side panels and the base panel to form a buoyant and collapsible container assembly;
• wherein the base panel is configured to mate with the top panel defining a smaller second internal volume and forming a substantially fluid-tight seal therebetween when the container assembly is in a collapsed position with the side panels removed from the top and base panels;
• retractable wheel assemblies attached to the base panel and being movable between a stored position and a deployed position;
• and
• a tow member removably attachable to the base panel and configured to releasably attach to a tow vehicle, the tow member being storable in at least one of the internal volume, the base panel and the top panel.

A reconfigurable transport container assembly, comprising:

• a base panel having base joinery;
• a retractable lift assembly integrally attached to the base panel and movable between a retracted position and an extended position;
• retractable wheel assemblies integrally attached to the base panel movable between a stored position and a deployed position and being configured to rollably support the container assembly for towing by a tow vehicle when the wheel assemblies are in a deployed position;
• a tow member releasably attached to the base panel and positioned to releasably engage the tow vehicle when the wheel assemblies are in the deployed position;
• a plurality of side panels removably attached to each other and to the base panel to define an internal volume;
• a top panel having top joinery and being removably attached to a plurality of side panels when the side panels are in an installed closed position to form a first configuration defining a transportable container assembly and being reconfigurable to a second configuration defining a substantially stationary structure different from the first configuration;
• and
• wherein each of the plurality of side panel further comprises base and top joinery that sealably mate with the base and top joinery of the base and top panels, respectively, forming pressure-ventable fluid-tight seals therebetween, and each of the plurality of side panels each have side joinery that sealably mates with the side joinery of adjacent side panels forming pressure-ventable fluid-tight seals therebetween.

A transportable container assembly, comprising:

• a substantially rigid molded base panel having a concave body portion and a floorboard removably connected to the body portion, the body portion shaped to define a storage area below the floorboard;
• a pair of substantially rigid molded end panels and a pair of substantially rigid molded side panels alternately removably attached to each other and to the base panel to define an internal volume, each of the end and side panels being independently movable relative to the base panel from a substantially upright, closed position to a lowered, open position to provide access to the internal volume;
• a substantially rigid molded top panel removably attached to the end and side panels to cover the internal volume when the end and side panels are in the closed position, the top panel being combined with the end and side panels and the base panel to form a transportable, collapsible container;
• when the end and side panels are in the closed position, releasable and sealable mating joinery portions of the end panels forming pressure-ventable substantially fluid-tight side panel joints with the respective adjacent side panels;
• when the end and side panels are in the closed position, first tongue-and-groove joinery formed between the base panel and each of the end and side panels, and second tongue-and-groove joinery formed between the top panel and each of the end and side panels, each of the first and second tongue-and-groove joinery forming pressure-ventable substantially fluid-tight seal there between;
• retractable lift assemblies recessed in the base panel and being movable between a retracted position, a first extended position and a second extended position, each lift assembly having a rotatable leg assembly, a jack assembly between the base panel and the leg portion, and a caster portion, the lift assemblies being configured to support the base panel above a support surface when the lift assemblies are in each of the first and second extended positions and to be substantially out of engagement with the support surface when in the retracted position, each caster assembly positioned to movably engage the support surface when the respective lift assembly is in the first extended position, the caster assembly being out of engagement with the support surface and the leg portion being in engagement with the support surface when the respective lift assembly is in the second extended position;
• a pair of retractable wheel assemblies attached to the base panel adjacent to a center portion thereof and being movable between a stored position and a deployed position;
• and
• a pressure release valve in fluid communication with the internal volume, the pressure release valve being structured to substantially equalize pressure differentials relative to ambient pressure.
