<p>PROBLEM TO BE SOLVED: To provide a paper container having a means for easily unsealing a folding ejection port. SOLUTION: The paper container comprises a bottom cut 12 provided on or in the vicinity of a border lateral crease 11 sectioning between a center gradient panel 6 and a body panel 10 approximately in parallel to the border lateral crease 11, an approximately U-shaped first half cut line 14 comprising a pair of side cuts 13a, 13b extending upward from both ends of the bottom cut 12 to the vicinity of a height of an intersection 20 of a longitudinal crease 7, lateral creases 8a, 8b and gradient creases 9a, 9b of a spout panel, and a pair of second half cut lines 15a, 15b within a region surrounded by the first half cut line 114 extending to broaden upward from two points below open ends of the both side cuts 13a, 13b and further extending upward without crossing the first half cut line 14 to reach in left and right inner top seal panels 4a, 4b. In addition, a tensile piece forming half cut line 16 symmetric with respect to an extension 7a of the longitudinal crease 7 is provided.</p> |
