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.

A system and method for cultivating plants is described. The system may include a tower structure having a vertical series of vessels for holding a netted pot or other container. The system may have a pressurized irrigation system that is in fluid communication with each vessel. The system may further include lamps to provide an adequate light source. The system may also include sensors, monitors and controls to establish and maintain environmental conditions suitable for proper plant growth. The system may further be implemented as a scalable system in which multiple tower structures may be installed into a scaffold system. Sets of towers may be slidably affixed to a scaffold such that the towers may be slid along a track thereby creating easy access to the plants, vessels, lights and the irrigation system. The system may be expanded to include multiple scaffolds affixed to a skeletal frame or compartment interior.

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 method is disclosed for storing and moving proppant. A supply of fracking proppant is provided at a remote location. A plurality of containers are provided to the desired location, each container having a top, a plurality of walls extending from the top and terminating at an outlet for discharge of proppant therefrom and a flow gate positioned adjacent the outlet to control flow of proppant from an interior volume of the container through the outlet. The plurality of containers are filled with fracking proppant at the remote location, then transported from the remote location to a well site location. The plurality of containers are staged at the well site location and the amount of proppant on hand at the well site location is tracked.

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.

A container or pod is specially constructed for hauling proppant in support of oilfield hydraulic fracturing operations. Dimensions are provided that comport with common dimensions in use for transportation of intermodal containers, with the containers being sized so as not to require special permitting from a regulatory standpoint when two such containers are loaded on a single trailer. A method of filling the containers is also provided, which include inverting the container to fill from a bottom gate that also serves as the discharge opening when the filled container is rotated back into an upright position.

A bulk fluid storage container has a top wall structure and a bottom wall structure held in spaced relation by a side wall structure. An internal baffle assembly is disposed in the fluid storage volume between the side wall structure for reducing fluid sloshing. A fill port formed in the top wall structure has a fill flange for coupling with a source of the fluid. A vent port formed in the top wall structure has a pressure vacuum value. A drain port formed in the side wall structure in a lower region adjacent the gutter region has a drain valve assembly is coupled to the drain port. A frame assembly includes an upper rectangular frame member and a lower rectangular frame member arranged in spaced relation by a plurality of post; wherein the frame assembly surrounds and supports the fluid storage vessel.
