<P>PROBLEM TO BE SOLVED: To provide a spouting plug for use of a liquid container capable of selecting a quantity to be poured and alleviating a reduced pressure condition in the container, with excellent sealability and good operability of an opening lever. <P>SOLUTION: A rubber-elastic cap is mounted rotatably on a spout. An engaging ring is provided around the outer peripheral surface of the upper end mouth of a spouting tube of the spout. A plurality of the engaging rings are provided on the inner peripheral surface of a circumferential wall of the cap. A top plate consists of an outer peripheral top plate and a center recessed top plate. The lower surface of the center recessed top plate is in tight contact with the upper end of the spouting tube of the spout. A large opening and a small opening consisting of an outer peripheral lower surface of the top plate and a tip of the circumferential wall are provided oppositely across the center line. The opening lever is raised at the center of the center recessed top plate. A plurality of reinforcing ribs are provided side by side in the direction orthogonal to the direction connecting the two openings in connection with the lower end on both side faces of the opening lever and the upper surface of the center recessed top plate. A plurality of reinforcing ribs are radially provided along the circumference in connection with the upper end inner peripheral surface of the circumferential wall, the lower surface of the outer peripheral top plate, and the lower surface of the outer periphery of the center recess of the top plate. <P>COPYRIGHT: (C)2007,JPO&INPIT |
