り、打栓装置への機械的な負担が軽減する。As shown in FIG. 1, the spout plug of the present invention has a sealing ring (13) for connecting the cap body (100) to the spout.
The outer peripheral shape of (0) is an outer peripheral portion (L 1 ) having an outer diameter larger than the inner diameter of the mouth portion of the spout, and a step (D) is formed on the upper outer peripheral portion.
And a lower outer peripheral portion (L 2 ) having an outer diameter smaller than the inner diameter of the spout that is continuous with the spout. When the cap body is fitted to the spout on the filling machine by a tapping method,
First, the cap ring is inserted into the spout opening from the lower end of the outer diameter smaller than the spout opening inner diameter of the sealing ring of the cap body, and the lower end serves as an introduction role, and then larger than the spout opening inner diameter. Since the upper part of the outer diameter fits into the spout mouth, even if the cap body and the spout are slightly off-center, the tip of the sealing ring of the cap body does not hit the spout mouth, and the spout Of the sealing ring is not damaged by the tip of the sealing ring. As a result, during the distribution process of the liquid container, the contents do not leak from the fitting portion between the cap body and the spout, and the operation of fitting the cap body to the spout on the filling machine becomes easy, and The mechanical load on the stopper device is reduced.
