A subterranean tank assembly is provided which broadly includes a vessel, a cover, and a riser which is configured to permit the riser to be adjusted in axial length at the job site. The riser is configured to permit coupling of the cover to the topmost connector portion thereof and to a portal of the vessel. The riser includes a plurality of substantially parallel, axially spaced circumferentially extending flanges which mate with the rim of the portal surrounding the opening, whereby the flanges may be fastened to the vessel in lengths intermediate to the initial length of the riser without the necessity of altering the tank or the cover.

Rotationally molded subterranean tank with riser

A pressurized tank dispenser assembly generally includes an extractor valve and a relief valve component mounted on a common fitting which may be held to a tank by a securement ring. The extractor valve permits pressurizing the tank and dispensing liquid by the attachment of a coupler thereon without the need for tools, while the relief valve component includes both vacuum relief and overpressure relief valves. The fitting is attached to the tank by the annular securement ring, whereby only a single opening through the tank is necessary to perform all operating functions of the tank.

Pressurized tank dispenser assembly

A method of rotationally molding a part to include a platform therein is provided. The method includes providing a mold and mounting the platform adjacent to, and preferably connected to the wall of the mold. Resin is deposited in the mold and the mold is closed. The mold is heated and rotated around at least two axes. The molten resin substantially covers the interior wall of the mold and the portion of the platform exposed therein. Rotation continues as the mold is cooled whereby the resin solidifies into a self-sustaining configuration. The resulting part is removed with the platform receiving resin thereon incorporated in the part resulting in a reinforcement oriented in spanning relationship to an interval defined by spaced-apart regions on the mold wall. The placement of the platform may be selected, whereby the resin and platform provide structural reinforcements for the part, lifting points incorporated into the part, or electrical grounding sites which are formed during molding.
