发明名称 LIQUID DISPENSING CONTAINER HAVING RIBBED CONSTRUCTION
摘要 71087-139 A plastic blow molded container (20) for holding liquids includes a rectangular body portion (22) having at least one rib (44,46) extending along each side wall of the container and having a construction that facilitates assembly of a unitary valve (42) to a dispensing spout (40) while maintaining flatness of side walls of the container during use. Each rib (44,46) has curved rib portions (48) extending along a pair of longer side walls (28). Each rib also has a relatively shallow rib portion (50) adjacent one shorter side wall (30) to prevent excessive compression thereof as the unitary valve (42) is pressed onto the dispensing spout (40). Each rib also has a relatively deep rib portion (52) along another shorter side wall (32) to maintain its flatness with the container filled and supported on the one shorter side wall (30) for the liquid dispensing through the valve (42). A top closure (38) of the container in addition to including the dispensing spout (40) includes a central handle (70) and a vent hump (72) having a label surface (74) that is inclined at about forty-five degrees with a vent (76) at its lower extremity to facilitate the liquid dispensing by admitting air into the container.
