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.

Abstract: A shell and retainer containment system for storing and transporting bottles, comprising an outer shell and an upper retainer. The outer shell includes a base, a number of sidewalls, and a top rim cooperatively forming a central cavity. The top rim includes a set of handles, a set of forklift fork openings for lifting the outer shell and retainer containment system via a forklift fork, and stacking geometry. The upper retainer secures the bottles in the central cavity and includes a brace and four corner reinforcements. The brace is positioned above the bottles and includes access openings for allowing access to bung openings of the bottles. The corner reinforcements extend upwards toward upper corners of the outer shell and include fastener openings for attaching the upper retainer to the outer shell via fasteners for securing the bottles in the central cavity.

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.

Abstract: An interlocking support foot and a container assembly including the support foot permits the support foot to be threaded onto a container but resists loosening of the foot by reverse rotation of the support foot once installed onto the container. The support foot is preferably molded of synthetic resin as a unitary member including a body, a threaded connector and at least one, and preferably a circular array of teeth radially spaced from the connector. The container is complementally configured to include a plurality of support areas for threadably receiving the support foot and provided with a threaded receiver and a radially spaced notch. When the support foot is installed on the support area of the container, the tooth engages the notch and resists reverse rotation of the foot.

Abstract: A protection and containment system for co-packaged containers is provided which includes a hollow primary container, a top protector complementally configure to fit atop the primary container, and at least one retainer coupled to the top protector for holding a secondary container. The primary container has a circumscribing upright sidewall and an opening configured for receiving material to be stored in the container. The top protector includes a side wall and at least a pair of spaced-apart opposed risers, most preferably provided as one of four corner modules, the risers extending upwardly from the primary container above the opening and presenting a gap between the risers which is sized and configured for receiving the secondary container. Several retainers can be provided, either to hold the secondary containers in different gaps, or provided in tandem to hold two secondary containers adjacent to one another in or proximate a single gap.
