Abstract
A plastics storge tank for fuel oil and the like is generally a parallelepiped basic shape. The pair of opposed tank walls of greatest dimensions are each provided with at least one channel-shaped horizontal recess. These recesses impart to the tank, as seen in horizontal section, a substantially cylindrical form over at least partial zones of said walls.
Claims20
A blow-molded plastics storage tank comprising a substantially parallelepiped basic shape and strengthened by at least one elongated recess extending across a pair of opposed tank walls, and at least one rectilinear elongated groove extending perpendicular to the at least one recess, each groove intersecting each recess in the same wall and extending beyond the at least one recess and each groove having a base portion forming a flat web which is disposed parallel to and attached to the flat web of a corresponding groove in the opposite tank wall, whereby the said tank walls are interconnected and supported relative to one another by said webs in the interior of the tank.
A blow-molded storage tank comprising plastics materials of substantially parallelepiped basic shape and with a pair of opposed tank walls having the greatest dimensions each having at least one elongated channel-shaped recess extending horizontally across said pair of opposed tank walls, the recesses imparting to said walls of the tank, as seen in horizontal section, a substantially cylindrical form over at least partial zones of the walls, each channel-shaped recess extending over the entire width of the tank and to a varying depth corresponding to the cylindrical form of said walls, at least one elongated vertical groove formed in each of said walls of the tank, each groove intersecting each channel-shaped recess in the same wall, each groove having a length less than the height of the tank and greater than the width of a channel-shaped recess and extending beyond the at least one recess, and each groove having a base portion interconnected to the opposite wall, whereby said walls are supported relative to one another.
