Abstract
A bag-in-carton 1 comprises a substantially rectangular parallelepiped carton 2, an inner bag 3 and a pouring spout 5 attached to an inclined panel of the carton 2. The inner bag 3 is adhered to inner-bag adhering regions 9 provided on the substantially entire parts of the inside surfaces of the inclined panel 2g, a pair of side panels 2b, 2d which are adjacent to the inclined panel 2g, and a side panel 2a. The inner bag 3 is also adhered partially to the inside surface of a side panel 2c which is remote from the incline panel 2g. When a content is drawn out through the pouring spout 5, the inner bag 3 is gradually released from the inside surface of the side panel 2 of the inside surface of the carton 2 and is deformed, moved to the pouring spout 5.
