PROBLEM TO BE SOLVED: To provide a combined member of a spout and a cap in which a ring is not deformed by an inertia force of fastening operation, a thin-walled segment is not damaged when the cap is fastened, the cap is shallowly installed at the spout before peeling off a seal member from the spout and the cap can be deeply installed at the spout after the seal member is peeled off from the spout. SOLUTION: This invention is comprised of a cylindrical spout with a male thread and a cylindrical cap with a female thread engaged with a male thread at the spout and set at this port. The cap has a cap main body and a ring connected to the cap main body via a thin-walled segment. This combined member of the spout and the cap is comprised of a plurality of ring ratchets spaced apart by a predetermined clearance at the inner surface of the ring. The outer surface of the is provided with a first engagement segment engaged with the ring ratchets to stop an operation of the ring in its closing direction, a second engagement segment engaged with the ring ratchets to stop an operation of the ring in its opening direction, and a ring ratchet receiving segment at an operator's side position of the engagement segment in respect to the rotating direction when the cap is fastened to prevent the ring from being deformed while being contacted with the lower surface of the ring ratchet. |
