PROBLEM TO BE SOLVED: To hinder the turn of an inner cap only with an inner cap hold member without using a pinching member, by disposing a positioning member to be locked in a jig onto an inner wall hanging from the lower face of the partition of a discharging cylinder so as to continue to the discharging cylinder. SOLUTION: In an inner cap A, a fitting cylinder 1 comprises an inner cylinder 4, an outer cylinder 5, and a shoulder wall 6, and a spiral engagement cylinder 3 with a discharging cylinder 2 connected to it extends upward from the inner cylinder 4. A projection 7 which engages with the periphery of a container mouth cylindrical part is formed all the way inside the lower end part of the outer cylinder 5, and a bulging part for the formation of fastening allowance is provided on the upper part of the periphery of the inner cylinder 4. When a cap B is spirally engaged with and secured on the inner cap A, the periphery of a sealing ring fits all the way inside the discharging cylinder 2 and forms a tight seal, the shoulder wall 35 of a cover cylinder 32 is joined to the shoulder wall 6 of the fitting cylinder 1 of the inner cap A, and the peripheral face of the outer cylinder 5 is covered with a side cylinder 36, so that the cover cylinder 32 is fitted over it. A hold member 41 has a hold base 42 equal in diameter as the inside of the inner wall 2 of the inner cylinder A, and a support tier part 43 for the placement of the lower end of a discharging cylinder. The inner cap A is slid over the hold base 42 of a jig C so that the longitudinal ribs of the inner wall of the inner cap A fit in the longitudinal grooves 44, and the inner cap is thrust down until the lower end of the inner wall is joined to the support tier part 43. |
