Claim Text:
1. A container closure integrally formed from a synthetic resin and including a body, which has an upper surface wall and a cylindrical side wall extending downwardly from a peripheral edge of the upper surface wall, and an outer lid, which has a top panel wall and a cylindrical skirt wall extending downwardly from a peripheral edge of the top panel wall, wherein the skirt wall of the outer lid and the side wall of the body are connected via first a hinge which defines a first pivot axis extending horizontally, and the outer lid is free to pivot, about the first pivot axis as a pivot center, between a closed position at which the upper surface wall of the body is covered and an open position at which the upper surface wall of the body is exposed; and a raised portion which rises upward and which has discharge ports formed on opposite sides thereof in a direction of the first pivot axis is disposed in a middle part of the upper surface wall of the body, wherein inner lids are connected to the raised portion via a second hinge, in association with the discharge ports, respectively, so as to be pivotable between a closed position at which the discharge ports are covered and an open position at which the discharge ports are opened; interference members are disposed on an inner peripheral surface of the skirt wall of the outer lid, in association with the inner lids, respectively, such that the interference members interfere with the inner lids to pivot the inner lids from the open position toward the closed position while the outer lid is being pivoted from the open position to the closed position, and then the interference members ride over the inner lids and become separated from the inner lids, and that the interference members interfere with the inner lids to pivot the inner lids from the closed position toward the open position while the outer lid is being pivoted from the closed position to the open position, and then the interference members are separated from the inner lids, and a barrier wall hanging down from a middle of an inner surface of an upper end wall of the raised portion to cut off from each other the discharge ports formed on the opposite sides of the raised portion in the direction of the first pivot axis is formed in the raised portion.
