A short cylindrical portion 7 having an outer diameter slightly smaller than the outer diameter is erected, and an engaging protrusion 8 is attached to the rear portion of the upper surface of the first top wall located inside the short cylindrical portion 7. Further, a spouting cylinder portion 9 is erected from the upper opening edge of the spouting hole 4 . In the figure, numeral 10 is a threaded portion that is screwed into the outer surface of the container mouth and neck (not shown), and 11 is a fitting cylinder portion that is watertightly fitted to the inner surface of the container mouth and neck.

The rotating member 2 includes a second rotating member that covers the upper surface of the first top wall.
A second peripheral wall 13 is provided vertically from the periphery of the top wall 12, and the second peripheral wall 13 is
It is made of synthetic resin and has a peripheral wall rotatably fitted to the upper outer surface of the first peripheral wall, and a through hole 14 corresponding to the spout hole 4 is bored in the second top wall. .

In the illustrated example, the second peripheral wall 13 is fitted onto the outer surface of the short cylindrical portion 7 via an uneven engagement means 15 in a manner that prevents it from coming off. Further, the through hole 14 is formed in the shape of a boss hole and is fitted into the upper outer surface of the spouting cylinder portion 9.
Furthermore, at the rear of the lower surface of the second top wall 12, an engaging piece 16 for making a sound and a protruding part 17 for a stopper, which engage and disengage with the engaging protrusion 8, are attached, respectively.

The auxiliary lid 3 has an auxiliary lid rear edge integrally attached to the rear edge of the cap main body 1 via an elastic reversing mechanism 18 to open and close the upper surface of the rotating member 2, and a third It is made of synthetic resin and has a rod-shaped stopper 20 hanging down from the back surface of the top wall 19, which is inserted through the through hole 14, and whose lower end is removably fitted into the spouting cylinder part 9.

The elastic reversing mechanism section 18 may be of any type, and in the illustrated example, it is a first hinge 18 that connects the cap body 1 and the auxiliary lid 3 on the left and right sides with an appropriate interval between them.
a, 18a, and an L-shaped elastic band plate part 18b is provided in the vertical direction between both hinges, and the joint part between the lower end of the band plate and the upper part of the cap body peripheral wall 6, and the upper end of the band plate part and the third top wall. The structure includes second and third hinges 18c and 18d provided at the joint portion with the hinge 19, respectively.
