A three-piece tank assembly including a tank, a support base, and a support liner. The tank has a conical bottom with a discharge conduit at its apex; a longitudinally corrugated antisplash filling trough integrally formed with a sidewall of the tank; and an integrally formed cover including a bunghole for providing access to the filling trough. The discharge conduit may include a flow valve and check valve. The base includes a sidewall for nesting engagement with the tank sidewall, a flat ground-engaging surface and transverse longitudinal slots for receiving the forks of a forklift. The support liner has an upstanding wall and a conical top wall for supporting the conical bottom of the tank and nesting within the support base. Mating projections and grooves in the tank and support base prevent relative movement of the three elements of the tank assembly. Each of the three elements is rotationally molded of cross-linked, high density polyethylene. Also disclosed is a method of forming an open-ended, inwardly projecting tubular member, or an open-ended outwardly projecting conduit, with or without a flange at its distal end, in a molded container.

A fastening insert adapted to be molded into the wall of a plastic container in order to provide a flat, fluid-tight sealing surface on the outer surface of the wall. The insert comprises a rigid annular base and a rigid rib which extends axially outward from the base. A plurality of threaded connectors are provided on the insert. The rigid rib and base prevent the plastic material from shrinking and sagging around the connectors during the plastic curing process.

A molded container with a hinged lid in which the hinge rod is partially exposed to function as a handle. Integrally molding axle bushings in the container body can support a wheeled axle. The container is characterized by a minimum number of parts which can be quickly and easily assembled after molding.

A spraying apparatus, which sprays herbicides, fungicides and insecticides mixed in water or liquid fertilizer, includes a fluid storage tank, a pump and one or more spray heads. An agitator, which is mounted in the fluid storage tank on the end of a bypass return pipe extending between the pump and the fluid storage tank, mixes the fluid in the fluid storage tank. The agitator includes a conical plate or cap overlaying the opening in the bypass return pipe. Spiral shaped fins or ribs are mounted on the concave side of the conical plate for directing the fluid from the bypass return pipe in a spiral rotating fashion to thereby mix the fluid in the fluid storage tank by imparting a gentle rolling action to the fluid. A nozzle between the bypass return pipe and the conical plate provides a fixed gap to control the fluid momentum in the fluid storage tank. The spraying apparatus also includes an anti-vortex device mounted on a fluid outlet pipe. This anti-vortex device, which prevents the formation of a gyrating vortex by forcing the fluid in the fluid storage tank to make a 90 degree turn as it is discharged, includes a cap which overlays the opening in the fluid outlet pipe at a fixed distance. The anti-vortex device prevents pump cavitation so that the pump operates more efficiently.

A drum capable of being molded in 55 gallon size from high density, cross-linked polyethylene. The drum body or shell has substantially cylindrical walls closed at both ends, respectively, by top and bottom end pieces or heads integral with the sidewalls. The drum includes an integrally molded hollow arcuate chime located at the intersection of the top end piece or head and the cylindrical sidewall and extending circumferentially around the drum. A plurality of rolling hoops located between the top and bottom end pieces extend circumferentially around the drum and protrude sufficiently outward from the drum walls to permit sufficient engagement by the forks of a forklift to support a fully loaded drum thereon. The drum may be reinforced by a plurality of inwardly protruding vertical ribs which run continuously substantially from the top to the bottom of the drum. The top end piece or head includes at least one bunghole integrally formed therewith. The bunghole is threaded to receive a bung and, preferably, is elevated from the plane of the top end piece.
