Abstract: A tank support for supporting a plastic product tank on a frame includes a plastic shell having a hollow interior and a base member nested in the hollow interior of the plastic shell. The base member is mounted to the frame, and a rod couples the base member to the plastic shell. By way of example, the plastic shell may be rotational molded in such a way that the plastic shell has a supporting surface which is complementary to a supported surface of the product tank.

Abstract: A plastic product tank for containing product under pressure has a lower funnel portion including a product outlet and an upper container portion having a product-containing capacity substantially greater than the lower funnel portion. The lower funnel portion and upper container portion are in substantially gas-tight communication with each other and the upper container portion of the tank includes side walls formed by a plurality of substantially planar surfaces adjacent to each other. Each interior angle between adjacent side walls of the upper container portion is greater than ninety degrees.
