Abstract
A pouring spout 5 is mounted on the front surface of a carton 2. The pouring spout 5 pierces through an inner bag. Only a region which is slightly larger than the half of the inner bag 3 on the pouring spout side is adhered to the inner surfaces of the carton by a paste. As the content is discharged, since the movable portion of the inner bag is injected into the fixed portion fixed on the inner surfaces of the carton, as the content is discharged, the volume of the inner bag is decreased.
