And the upper horizontal folding line 41 are provided so that an angle θ1 is larger than 90 degrees. Further, the cut 61E is provided such that an angle θ2 formed by the extension line L2 of the straight line portion 61A and the upper horizontal folding line 41 is larger than the angle θ1.

[Opening the carton]
When the carton 1 is opened, the gripping portion 21E is gripped, and the gripping portion 21E is pulled up so as to be folded at the upper horizontal folding line 41. Thereby, the 1st end plate 21 is cut | disconnected to the position of the upper horizontal fold line 41 along each linear part 62A, 62B and each expansion part 62C, 62D, and the side surface opening 52 is formed. Next, in order to form the top surface opening 51, the gripping portion 21E is folded back to the top surface portion 4 side by the upper horizontal fold line 41, and the first opening that is perpendicular to the upper horizontal fold line 41 is shown in FIG. Pull in direction D1.

  Here, since the boundary line portion 63A extends from the intersection C1 in the first opening direction D1, the cutting resistance when the grip portion 21E is pulled in the first opening direction D1 is small, and it is easy to be cut. On the other hand, since the arc portion 63B is provided in the direction away from the boundary line portion 63A toward the first opening direction D1 from the second expanded portion 62D, the cutting resistance is larger than the boundary line portion 63A. Hard to be cut. For this reason, when forming the top surface opening 51, the boundary line portion 63A is first cut. Thereafter, as shown in FIG. 4, by pulling the gripping portion 21E in the second opening direction D2 orthogonal to the straight line L3 connecting the intersection C2 and the intersection C3, the top surface portion 4 extends from both ends of the arc portion 63B to the arc portion 63B. And the top surface opening 51 is formed. Thereby, the top surface opening 51 is formed continuously to the side surface opening 52, and the outlet 5 is formed.

[Drawing and holding food containers]
When taking out the food container 7 from the carton 1, the exposed portion of the food container 7 at the outlet 5 is gripped, and the food container 7 is pulled up obliquely upward to the continuous part side of the top surface opening 51 and the side surface opening 52. Then, as shown by an arrow and a two-dot chain line in FIG. 5, the first end plate 21, the first inner end plate 23, and the first outer end plate 25 are pushed outward by the food container 7, and the outlet 5 is at the corner 20. In order to expand, the food container 7 can be taken out from the outlet 5.

  The food in the taken out food container 7 can be warmed together with the food container 7 in a microwave oven or the like. At this time, since the food container 7 is also heated, the food container 7 becomes hot, and it is difficult to take out the food container 7. Therefore, if the food container 7 is heated while being held at the outlet 5, the carton 1 can be grasped and taken out from the microwave oven or the like. When the food container 7 is held at the outlet 5, as shown in FIG. 6, the flap 21A is inserted into the insertion portion 25A from the outside, and then the removed food container 7 is inserted into the top surface opening 51. Thereby, as shown in FIG. 7, the collar portion 71 </ b> B of the food container 7 is locked to the top surface portion 4, and the food container 7 is held at the outlet 5.

  According to the above embodiment, since the outlet forming line 6 is connected to the corner 20 which is a discontinuous portion, if the outlet 5 is formed by the outlet forming line 6, the corner of the outlet 5 and the corner are formed. The part 20 can be made continuous. For this reason, since the take-out port 5 can be expanded at the corner 20, the food container 7 can be taken out from the wide take-out port 5. On the other hand, when the food container 7 is held, the food container 7 can be held in the outlet 5 as it is. Accordingly, since the food container 7 can be taken out and held at one outlet, the food container 7 can be easily taken out at the time of opening, and the food container 7 can be held without trouble.

  Further, since the flap 21A is provided on one of the first end plate 21 and the first outer end plate 25 adjacent to each other with the corner portion 20 interposed therebetween, and the insertion portion 25A is provided on the other side, the flap 21A is inserted into the insertion portion 25A. Thereby, the intensity | strength of the trunk | drum 2 can be raised. Therefore, the stability when the food container 7 is held at the outlet 5 can be increased.

  Further, since the outlet forming line 6 extends from the intersection C1 with the corner portion 20 onto the upper horizontal folding line 43 that is a boundary line between the top surface portion 4 and the body portion 2, the side of the outlet 5 in the top surface portion 4 The edge can be extended to the boundary line between the top surface portion 4 and the trunk portion 2. Accordingly, the food container 7 can be easily taken out from the outlet 5.

[Modification]
It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, the trunk | drum 2 should just be discontinuous in the corner | angular part 20 to which the exit formation line 6 is connected, and the other corner | angular part 20 does not need to be discontinuous.
Each of the end plates 21, 22 may not include the flaps 21A, 21B, 22A, 22B.
The insertion portion 25 </ b> A may be provided in the second outer faceplate 26 instead of the first outer faceplate 25, or may be provided in the first outer faceplate 25 and the second outer faceplate 26, respectively.
