  • Patent number: 11511936
    Abstract: 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.

  • Patent number: 11279554
    Abstract: 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, several buttresses, and several horizontally extending ribs. The tank portion includes several curved sidewalls and a fill opening. The leg supports include lower 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 horizontally extending ribs minimize outward deflection due to hydrostatic loading and/or pressurization. The connection systems include washers that allow for shrinkage and expansion between the molded container and the pallet in a number of directions.

  • Patent number: 10994893
    Abstract: A liquid storage tank broadly comprising a drum, a bottom chime, and a top chime. The bottom chime and top chime each include drum engaging geometry for positively connecting the chimes to the drum and retaining the chimes on the drum when the drum is holding liquid and subjected to lifting forces. The top chime also includes forklift openings and alignment and anti-rotation geometry configured to prevent the top chime from rotating relative to the drum when the drum is lifted via a forklift fork extending through the forklift openings so that the forklift fork does not damage a top wall or bung openings of the drum.

  • Patent number: 9657855
    Abstract: A combination flow control and reverse flow check valve controls the flow of fluid in a desired downstream direction and limits undesired backflow of liquid in an upstream direction into a fluid source such as a reservoir. The flow control and reverse flow check valve may include a housing having a fluid conveying channel with an upstream end configured for mounting to the liquid source and a downstream end for discharging fluids, a flow control valve positioned between the ends, and a check element positioned in the channel between the flow control valve and the downstream end. The check element is advantageously positioned between the flow control valve and the downstream end of the housing to prevent possible contaminants in a backflow liquid from reaching the flow control valve.

  • Publication number: 20160130080
    Abstract: A container includes a hollow container body and a container connector including a central outlet, an annular groove, and an annular rib. The container and container connector are formed of a molded thermoplastic material or any other suitable material. The annular groove allows the container connector to bend outwardly due to internal pressure of the container without the central outlet warping outwardly.
