ている。As shown in FIG. 2, the spout main body 2 has a flange 21 for attaching to a hole provided in the carton C.
And a sealing member 24 integrally formed in the middle of the inner wall of the tubular portion 22 via a thin portion 23. Further, the sealing member 24 is provided with an upward convex portion 25, a pull ring 26 directed upward is provided on an upper portion of the convex portion 25, and a downward facing is provided on a middle stage of a side surface of the convex portion 25. A projection 27 having a taper is provided around the circumference. Further, a male screw 28 for screwing with the cap 3 is formed on the outer periphery of the tubular portion 22.

液を注出する。When the content liquid is poured out from the carton C, first, the pull ring 26 is pulled upward with a finger to separate the sealing member 24 with the thin portion 23 and the convex portion 25 into the hole 32 of the cap 3. Raise along. By pulling the pull ring 26 in this manner, the projection 27 on the side surface of the convex portion 25 of the sealing member 24 passes through the hole 32 of the cap 3 so as to slightly spread it, and as shown in FIG. The sealing member 24 is held by the cap 3 in a state where the lower side of the protrusion 27 is locked to the edge, and the spout 1 is in an opened state. In this opened state, the cap 3 is rotated and removed from the spout main body 2, and the carton C is tilted to pour out the content liquid.
