The present invention relates to a container for holding bulk material, having a closable inlet for the bulk material in the upper closure of the container, a cross-sectional geometry narrowing in the outlet direction for the bulk material, an outlet tube for the bulk material arranged subsequently in the outlet direction, a first reversible mechanical closure device (A), which is arranged in the transition region from the container body to the outlet tube or in the outlet tube itself and, by opening, releases the bulk material from the interior of the container, and a second closure device (B) which reversibly closes the mouth of the outlet tube, the second closure device being a cover which is pressed flush onto the mouth of the outlet tube by means of a closure device, there being a seal which seals the outlet tube in a gas- and liquid-tight fashion from the external environment at least on the contact surface of the cover with the mouth degree of the outlet tube, wherein the cover is screwed onto or is pressed with a clamping ring or a bayonet closure onto the mouth of the outlet tube.

A tank for bulk material storage and transport and method for producing same. In an embodiment, a tank is provided that includes a shell having a sidewall, a neck including a first collar, and a tube terminating in a second collar. A frustoconical cap may be secured to the first collar. A substantially conical cap may be secured to the second collar. A liner may be applied to the shell so that the liner substantially covers an interior surface of the sidewall, an interior surface of the neck, at least a portion of the first collar, an interior surface of the tube, and at least a portion of the second collar. Annular thickened segments may be trimmed to prepare the tank for use. The annular thickened segments may be located at an interior joint between the frustoconical cap and the first collar, and/or an interior joint between the substantially conical cap and the second collar. The trimming step may form first and second sealing surfaces of the liner adjacent respectively to the first and second collars. The first and second sealing surfaces may respectively be configured to substantially seal against a manway cover and an outlet cover. In a final, assembled preferred form, the frustoconical and substantially conical caps are replaced with the manway assembly and outlet cover, respectively sealed against the first and second sealing surfaces.

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 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 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 container is configured to receive bulk material therein and to experience a pressure differential for which an internal container pressure is greater than ambient pressure. The container includes a receptacle and a removable lid. The receptacle defines a chamber to receive material. The receptacle includes a fill neck that defines a receptacle opening in fluid communication with the chamber. The lid covers the receptacle opening in an engaged condition to enclose the chamber. The receptacle includes a receptacle connector with spaced apart connector teeth, and the lid includes a lid connector with spaced apart connector lugs. The receptacle connector and the lid connector cooperatively providing a fractional-turn connection where the connector teeth and lugs are rotatable into and out of engagement with one another in the engaged condition to restrict lid separation from the fill neck associated with the pressure differential.

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.

Bins for storing and/or dispensing a material, such as preferably a flowable material. In some embodiments, the bin may comprise a body comprising an inner storage chamber configured to receive and store a flowable material therein. A forklift base may be coupled to the body and may comprise one or more pairs of forklift slots configured to receive forks of a forklift to allow the storage bin to be lifted and transported. A dispensing gate may be slidably positioned adjacent to a dispensing opening in the body to allow for positioning between a closed configuration in which the flowable material is blocked from being dispensed from the inner storage chamber and an open configuration in which the dispensing gate is moved away from the dispensing opening to allow the flowable material to exit the inner storage chamber.
