Claims

[Scope of utility model registration request]

In a bag-in-box, in which a bag for filling, which is made of a plastic film or a laminate made of a plastic film, is accommodated in a carton-made box, the bag is in an empty state and a side piece and a second side piece; three side pieces and a fourth side piece, the bag having a first heat seal formed at the center between the first side piece and the second side piece at the bottom; The first side piece, the third side piece, the fourth side piece, and the second side piece all have a second heat-sealed portion formed over the entirety, and a third side piece. The two opposing fold-out pieces of the side piece and the fourth side piece are not heat-sealed above the second heat-sealed portion, and each fold-out piece and the first side piece or second side opposite thereto A heat-sealed end is provided between the heat-sealed portion and the heat-sealed end on a straight line extending above the heat-sealed portion and at an angle of 45° from the boundary between the first heat-sealed portion and the second heat-sealed portion, or on the inside thereof. A bag characterized by having a third heat-sealed part formed so that the edge is located.
