Plastic blow-molded container having dispensing valve

A plastic blow-molded container for liquids comprising:

• a body portion sized to hold a plurality of gallons of liquid contents and having first and second pairs of side walls;
• both pairs of the side walls being generally flat and one pair having a substantially longer horizontal extent than the other pair;
• upper and lower inwardly projecting ribs extending completely around the body portion along each side wall thereof;
• the ribs projecting farther inward along the longer pair of side walls than along the shorter pair of side walls to provide the body portion with an elongated rectangular shape;
• each rib having upper and lower rib walls;
• the lower rib wall of the upper rib and the upper rib wall of the lower rib having flat shapes along the longer pair of side walls;
• the upper rib wall of the upper rib and the lower rib wall of the lower rib having curved shapes along the longer pair of side walls;
• each rib having a vertical connecting wall extending completely around the body portion and connecting the upper and lower rib walls thereof with an inwardly curved shape along the longer pair of side walls;
• a generally flat bottom wall for closing the bottom end of the body portion;
• a top closure for closing the top end of the body portion;
• said top closure being unitary with the body portion and the bottom wall and including an upper handle located centrally between both the longer and shorter pairs of side walls;
• the top closure also including a spout that projects upwardly between the handle and one of the shorter side walls;
• said spout projecting in a vertical direction perpendicular to the bottom wall;
• said top closure further including an upwardly projecting vent hump located toward the other shorter side wall from the handle on the opposite side thereof as the spout;
• and a unitary valve mounted on the spout and movable from a closed position to an open position to permit dispensing of liquid contents of the container when supported sideways on said one shorter side wall of the body portion.
