The gable-top container 1 described above is formed from the gable-top container panel 10 shown in FIG. 2 by the following procedure.
First, the seal panels 25, 35, 45 of the gable-top container panel 10 are heat-sealed to the body panel 24, bottom panel 34, and end wall panel 44 to form a carton blank. The carton blank is then shaped into a rectangular tube. In this state, while folding the bottom panels 31 and 32 along the valley fold lines 311 and 321, they are folded inward between the bottom panels 33 and 34 along the bottom lateral fold lines 31A and 32A, and overlapped with the bottom panels 33 and 34. . Then, the entire overlapping portions of the bottom panels 31 to 34 are heat-sealed to form the bottom portion 3 .

After that, while folding back the second folded portions 434 and 444 along the valley fold lines 432 and 442, the first folded portions 433 and 443 are folded inward along the upper horizontal fold lines 43A and 44A to form a gable wall between the roof panels 41 and 42. The panels 43 and 44 are folded. At this time, the roof panels 41 and 42 are folded inward along the upper horizontal folding lines 41A and 42A in conjunction with the folding of the end wall panels 43 and 44. As shown in FIG. Then, the roof panels 41 and 42 are valley-folded along the valley-fold lines 411 and 421, and the end wall panels 43 and 44 are mountain-folded along the mountain-fold lines 431 and 441. The upper ends 435,445 of the wall panels 43,44 are interposed between the upper ends 412,422 of the roof panels 41,42. The upper ends 412 , 422 , 435 , 445 are then heat sealed together to form the top seal 46 .

When opening the gable top type container 1, the roof panels 41 and 42 are separated from each other while inserting a finger between the pair of roof panels 41 and 42 on the side of the gable wall panel 43, and the roof panels 41 and 42 and the gable wall are separated. The panel 43 is folded back. In this state, the end wall panel 43 is projected forward while applying force to the top seal 46 from the left and right directions, thereby separating the end wall panel 43 from the roof panels 41 and 42 and unsealing. As a result, a spout is formed by the gable wall panel 43, and by tilting the spout side forward while holding the gable-top container 1, the user can pour the beverage liquid or the like inside through the spout. becomes.

It is possible to further improve the graspability.

According to the above-described embodiment, the body panel 24 on the side of the non-opening portion positioned on the upper side when pouring a beverage or the like has a width greater than the width of the body panel 23 on the side of the opening portion positioned on the lower side. Since the widened wide portion 241 is provided, it is possible to improve the gripping property of the gable-top container 1 with a simple structure.

In addition, since the trunk panel 24 on the non-opening portion side and the trunk panel 23 on the unsealing portion side have the same width on the bottom portion 3 side, the area on the bottom portion 3 side of the cylindrical trunk portion 2 does not protrude in the width direction. When a plurality of gable-top containers 1 are accommodated in the case, it is possible to prevent the gable-top containers 1 from interfering with each other.

In addition, since the wide portion 241 is provided at a height position where the user tends to grip the gable-top container 1, gripping of the gable-top container 1 can be effectively improved.

In addition, since the gable-top container 1 is used to store drinking liquids such as milk, dairy beverages and juices, and gel-like foods such as yogurt and jelly, the versatility of the gable-top container 1 can be utilized.
