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.

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.

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.

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.

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.

A combination flow control and reverse flow check valve provides a compact valve unit for controlling the flow of fluid in a downstream direction and limiting undesired backflow of liquid into a source such as a reservoir. The flow control and reverse flow check valve may be provided as a unitary member having a housing with an upstream end configured for mounting to the liquid source, a fluid conveying channel within the housing, and a check element positioned in the channel between the flow control valve, such as a ball valve, and a seat which is complementally configured with the check element to normally seal against backflow. A blocking element may be provided to prevent interference of the check element with the operation of the flow control valve while permitting liquid to flow in an intended downstream direction. Because the occurrence of a backflow event is an undesired and infrequent event which may necessitate investigation, the check element may be sized and made of a material which will move past the seat during pressurized flow, thereby providing an indicator that a backflow event has occurred when the check element is found within the source.

A torque arm restraint is provided with a body having a bore including an axis and an arm extending from said body transversely to the axis and is adapted for resisting torque applied to the fitting of a liquid storage tank, and is configured either for mounting on a fitting or as a component of the fitting such as an outlet fitting mounting a pipe and extending from the wall of the tank. A tubular body permits passage of instrumentation or liquid therethrough and the arm may have an abutment surface positioned proximate the inside surface of the tank wall, either in engagement or in spaced relationship, whereby the arm resists torque applied to the fitting exteriorly of the tank. The body may include an attachment member which is adapted for mounting to a tank fitting, and may be coupled to a pipe within the tank.
