A container which is useful for safely storing and transporting compositions, such as liquid organic peroxide-containing compositions, which may be flammable, combustible, susceptible to exothermic decomposition, explosive and/or otherwise hazardous, is provided. The container includes a containment vessel having thermoset polymer-containing walls, as well as a vent mechanism. The containment vessel may be manufactured by a rotational molding process using a thermoplastic polymer, such as a polyethylene, which is crosslinked to provide the thermoset polymer.

An intermodal container includes first and second ends, joined by first and second sides in a generally rectangular configuration. A generally continuous floor cooperates with the first and second ends and the first and second sides to form an open top container. A plurality of roof overhangs extend adjacent a top of the open top container, generally parallel to the floor. The intermodal container includes a roll cover having a first position in which the open top container is substantially open to the ambient environment to allow for loading from above the first and second sides and first and second ends of the open top container. The roll cover has a second position in which the open top container is substantially closed to the ambient environment to prevent any contents of the open top container to be ejected from the open top container during transport. A plurality of top reinforcement rails are disposed adjacent upper portions of the first and second sides, and extends from the first side to the second side.

A container includes a receptacle including an upright receptacle side and a receptacle bottom that cooperate to at least partly define a container chamber. The bottom presents a peripheral margin, with the side being attached to the bottom along the peripheral margin and extending upwardly relative to the bottom along an upright container axis. The receptacle further includes a drain configured to permit material flow out of the chamber, with the drain intersecting the bottom to define a drain opening that fluidly communicates with the chamber. The drain opening is spaced inboard from the peripheral margin and is laterally offset from the container axis in an offset direction. The bottom includes first and second floor sections extending inboard from the peripheral margin and joined relative to each other along a first gutter area adjacent the drain opening. The first floor section slopes downwardly toward the first gutter area in the offset direction and the second floor section slopes downwardly toward the first gutter area in a direction opposite the offset direction, with the floor sections configured to cooperatively advance material within the chamber toward the drain opening.

A stackable container system is configured to provide stacked receptacles for receiving bulk material therein. The stackable container system includes a first receptacle configured to provide a respective stacked receptacle. The first receptacle includes a receptable bottom, a receptable top, and a receptacle side extending along an upright container axis between the receptacle bottom and top, with the first receptacle presenting a container chamber. The receptacle top is configured to at least partly support another one of the stacked receptacles stacked relative thereto along the upright container axis. The receptacle top and the receptacle side have, respectively, a top peripheral margin and a side peripheral margin that extend laterally about the upright container axis, with at least part of the top peripheral margin being laterally outboard of the side peripheral margin. At least part of the top peripheral margin is interconnected to the side peripheral margin along a transition section that extends laterally between the receptacle top and the receptacle side.

An intermediate bulk container (IBC) system including a base and walls, and having an interior space. The system comprises a drain in the base or in a wall, a liner bag having a liner bag drain couplable to the drain in the base or in a wall, and a door coupled to the wall by a hinge and shaped to cover an opening in the wall. The opening extends from a top of the wall. The hinge is coupled to the door to allow the door to rotate into the interior space. A stop prevents the door from rotating beyond the wall. The system may be used by rotating the door into the interior space to expose the opening, reaching through the opening and operatively coupling the liner bag drain at the drain in the base or in a wall, and rotating the door to cover the opening.

A stackable container system is configured to provide stacked receptacles for receiving bulk material therein. The stackable container system includes a first receptacle configured to provide a respective stacked receptacle. The first receptacle includes a receptable bottom, a receptable top, and a receptacle side extending along an upright container axis between the receptacle bottom and top, with the first receptacle presenting a container chamber. The receptacle top is configured to at least partly support another one of the stacked receptacles stacked relative thereto along the upright container axis. The receptacle top and the receptacle side have, respectively, a top peripheral margin and a side peripheral margin that extend laterally about the upright container axis, with at least part of the top peripheral margin being laterally outboard of the side peripheral margin. At least part of the top peripheral margin is interconnected to the side peripheral margin along a transition section that extends laterally between the receptacle top and the receptacle side.

A transport and storage container for liquids includes a pallet-type understructure for an inner container made of plastic, the inner container having four side walls, a sealable filling socket formed on an upper bottom and an outlet socket formed on the lower portion of a side wall and having a tapping fitting, the container comprising a cage having horizontal and vertical bars made of metal for receiving the inner container, at least two vertical bars disposed on opposite side walls, being connected at connecting portions by a traverse bar extending over the upper bottom of the inner container which is formed by a hollow profile, the vertical bars having a cross section recess for decreasing a shear force acting on the connecting screw in transition portions formed adjacent to the connecting portions.

A container includes a receptacle including an upright receptacle side and a receptacle bottom that cooperate to at least partly define a container chamber. The bottom presents a peripheral margin, with the side being attached to the bottom along the peripheral margin and extending upwardly relative to the bottom along an upright container axis. The receptacle further includes a drain configured to permit material flow out of the chamber, with the drain intersecting the bottom to define a drain opening that fluidly communicates with the chamber. The drain opening is spaced inboard from the peripheral margin and is laterally offset from the container axis in an offset direction. The bottom includes first and second floor sections extending inboard from the peripheral margin and joined relative to each other along a first gutter area adjacent the drain opening. The first floor section slopes downwardly toward the first gutter area in the offset direction and the second floor section slopes downwardly toward the first gutter area in a direction opposite the offset direction, with the floor sections configured to cooperatively advance material within the chamber toward the drain opening.

A molded container assembly includes a pallet, a molded container, and a plurality of connection systems. The pallet supports the molded container thereon and includes stacking alignment structure for stacking the pallet on another molded container assembly. The molded container includes a tank portion, several leg supports, and several buttresses. The tank portion includes several curved sidewalls and a fill opening. The leg supports include lower sections and upper sections that extend above the fill opening for spacing a pallet stacked on top of the molded container above the fill opening. The upper sections include pallet engaging structure for engaging pallets of at least two different types. The buttresses extend between the tank portion and the leg supports. The connection systems include washers that allow for shrinkage and expansion between the molded container and the pallet in a number of directions.
