ABSTRACT:
A pouring spout for a liquid container has a film attached to a pouring hole from inside of the container and a tab tape for covering the pouring hole from outside of the container. The film includes a portion for forming a pouring opening corresponding to the pouring hole, and a lip forming portion along the portion for forming the pouring opening. The tab tape is peelably adhered to the film and a peripheral edge of the pouring hole, the joining portion between the film and the tab tape being inflated outwardly or inwardly of the container. When the tab tape is torn from the container, the lip forming portion is positioned to protrude outwardly.
