BAG-IN CARTON

PROBLEM TO BE SOLVED: To provide a flip-top bag-in carton good in openability and re- sealability of an inner bag. SOLUTION: A cover lid consisting of a lid part top panel 2, a lid part front panel 1 and two lid part side panels 3 is connected to a square pole-shaped body part by the upper side of the rear panel of the square pole-shaped body part and the rear side of the lid part top panel 2 and the square pole-shaped body part and the cover lid consisting of the lid part side panels 3 are mutually connected while the side panels are mutually connected by the connection pieces folded in the cover lid to form a carton and an inner bag is bonded to the inside of the carton to obtain a bag-in carton. A part of the body part front panel 12 and a part of the body part side panels 11, 13 near to the front panel of the square pole-shaped body part are molded so as to become lower than the body part rear panel to increase the exposed degree of the inner bag at a time of opening. By this constitution, the opening re-sealing properties of the inner bag are improved and the body part can be divided by a jipper J formed by parallelly arranging Y-shaped notches.
