ABSTRACT:
An inner bag is adhered by an adhesive to the substantially entire region of a pouring spout attaching panel of a carton blank, and to substantially half regions of panels bordering the pouring spout attaching panel, which are on the side of a pouring spout. The inner bag is adhered to the carton at a part which is remotest from the pouring spout and is normal to a direction of movement made by the inner bag when air is drawn. The inner bag is adhered to the carton blank at the substantially entire region of the pouring spout attached panel, and four corners on the side of the panel, which enables the inner bag to be set up into a square shaft with high precision upon the setting-up of the carton blank.
