Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A reusable sanitary valve assembly with a releasable cap or cover that disengages from the valve indicating an over-pressure situation has occurred, the cap or cover is capable of being reset, and once it is known that gas, liquid or other contaminants have possibly entered the valve following an over-pressure situation, the interior of the valve can be inspected by removing a portion of the valve while the valve remains sealed on a pressurized substrate and, if the interior of the valve is contaminated, the interior of the valve can be cleaned and closed without unseating the valve.

Abstract: A double walled tank (12) is provided which includes an outer shell (14), a telescopically interfitted inner shell (16), and a cover (18) secured to outer shell (14). The tank (12) includes at least one spacer (48) located between the inner and outer shells (16, 14), as well as resilient seals (38, 72) serving to maintain an appropriate and safe spacing gap between the shells (14, 16). The inner shell (16) includes a top wall (38) equipped with a fill opening (52) defined by an upstanding central flange (50, 50a) surmounted by a detachably secured cover (54, 54a).
