Claim Text:
1. An integrally formed synthetic resin container closure comprising: a body including an upper surface wall and a cylindrical side wall extending downwardly from a peripheral edge of the upper surface wall; an outer lid including, when in a closed position, a top panel wall and a cylindrical skirt wall extending downwardly from a peripheral edge of the top panel wall; a first hinge connecting the cylindrical skirt wall of the outer lid and the side cylindrical wall of the body, whereby the outer lid can pivot between the closed position covering the upper surface wall of the body and an open position exposing the upper surface wall of the body; a discharge tube disposed on the upper surface wall and extending out and away from the first hinge; a discharge port coupled to a portion of the discharge tube; an inner lid connecting to an upper surface of the discharge tube via a second hinge, whereby the inner lid can pivot between a closed position covering the discharge port and an open position opening the discharge port; an interference mechanism disposed on an inner peripheral surface of the skirt wall of the outer lid and being configured to each of: a pressing mechanism configured to contact the inner lid to force the inner lid into the closed position while the outer lid is being pivoted from the open position to the closed position; the pressing mechanism being arranged on at least one of: the inner lid being a plate-shaped member having ends jutting out beyond opposite side surfaces of the discharge tube; a seal ring being configured to engage the discharge port is arranged on a central part of an inner surface of the inner lid; stop projections arranged in opposite side portions of the inner surface of the inner lid; receiving projections extending out and upwards from opposite sides of the discharge tube; the stop projections being configured to ride resiliently over the receiving projections when the inner lid is pivoted from the closed position to the open position and when the inner lid is pivoted from the open position to the closed position; the second hinge comprising: the first opposite side hinge being located further widthwise outward of one of the receiving projections and the second opposite side hinge is located further widthwise outward of another of the receiving projections; the central hinge and the first and second opposite side hinges being thin-wall sections arranged horizontally in a straight line; and extending-out pieces extending out and upwardly and bilaterally from an upper surface of the discharge tube, wherein the central hinge and the first and second opposite side hinges are connected to portions of the extending-out pieces.
