PROBLEM TO BE SOLVED: To easily separate most parts of a plastic pouring mouth cock from a container body, by providing a cylindrically extension pouring mouth stuck on a connection part formed at the external peripheral face of a cylindrical part. SOLUTION: A pouring mouth-fitting part B is integrally attached to the external face P1 of a liquid packaging container body P. After it has been attached, a temporary cap D1 is put on the upper opening of the pouring mouth- fitting part B, while a extension pouring mouth C is fitted to the pouring mouth- fitting part B. When the content charged in the inside of the container body, P is taken out, the extension pouring mouth C is connected to the pouring mouth-fitting part B through true connection parts 2, 12 by a fitting system or a screwing system to extend the delivery opening part and unseal a seal film 6 by sticking and breaking it by the front end of an unsealing blade 14 of the extension pouring mouth C. A cap D is put on the upper opening of the extension pouring mouth C. |
