Liquid dispensing container having ribbed construction

DETAILED DESCRIPTION What is claimed is: 1.
A plastic blow molded container for holding liquids, comprising: a hollow body portion having bottom and top ends; said body portion having first and second pairs of generally flat side walls extending between the bottom and top ends of the body portion; one of said pairs of side walls having a longer horizontal extent than the other pair to provide the body portion with a horizontally elongated rectangular shape between its bottom and top ends; a bottom wall that closes the bottom end of the body portion; a top closure that closes the top end of the body portion has a central handle and also has a dispensing spout located adjacent one of the shorter side walls in a remote relationship to the other shorter side wall; a unitary valve that is pressed onto the dispensing spout to provide dispensing of liquid contents with the container supported on said one shorter side wall; at least one rib extending horizontally around the body portion of the container along each wall and projecting inwardly toward the interior of the body portion; said rib including curved rib portions along the pair of longer side walls to maintain the flatness thereof when the container is filled with liquid; said rib having a relatively shallow rib portion along the one shorter side wall adjacent to and on one side of the central handle and the dispensing spout to prevent excessive compression of the one shorter side wall as the unitary valve is pressed onto the dispensing spout; the rib having a relatively deep rib portion along the other shorter side wall on the opposite side of the central handle and dispensing spout from the shallow rib portion to maintain the flatness thereof with the filled container supported on the one shorter side wall for the liquid dispensing through the unitary valve; and the shallow and deep rib portions extending horizontally along the pair of shorter side walls of the body portion at the same elevation as each other.
2.
A container as in claim 1 wherein the central handle is located midway between both pairs of side walls, the top closure having a vent hump that supports the handle on the side thereof toward the shorter side wall having the deeper rib, the vent hump having a label surface that extends downwardly from the handle at an inclination of about forty-five degrees, and the vent hump having a vent at the lower extremity of the label surface
