Along with this, the spout 7 takes an inclined posture with respect to the x direction. The shapes of the front seat 1 and the rear seat 2 maintain a circular or elliptical shape as long as the contents 69 are accommodated. Therefore, the spout 7 takes a stable and tilted posture. As a result, when the content 69 is poured out from the spout 7, the orientation of the spout 7 is less likely to become unstable, and the content 69 can be poured out more stably. Therefore, according to the pouch container / packaging body C1, the contents can be appropriately poured out while expanding the volume of the accommodating portion 6 by providing the heaven gusset sheet 3.

As shown in FIG. 8, the pouch container B1 has a circular shape or an elliptical shape as a whole in the z-direction while the spout 7 faces in an oblique direction, so that the purchaser of the pouch container package C1 has an arc shape. It is possible to stably and appropriately pour out the contents 69 from the spout 7 while holding the pouch container / packaging body C1 so that the hand Hd is aligned with the rear seat 2. Unlike the present embodiment, for example, when the spout 7 is in the posture along the x direction, the pouch container covers the rear side seal portion 52 and the side seal portion 56 located on the opposite side of the spout 7 by the hand Hd. It is forced to grip and dispense the package C1. In this case, the rear side seal portion 52 and the side seal portion 56 may cause a pain in the purchaser's hand Hd, and the orientation of the spout 7 is also difficult to stabilize. According to the present embodiment, it is possible to avoid such a painful feeling, and it is possible to make the orientation of the spout 7 more stable.

Further, when the pouring from the spout 7 is performed intermittently, a part of the pouring contents 69 may adhere to the outer surface of the pouch container B1 along the spout 7. According to the present embodiment, as shown in FIG. 7, a gentle V-shaped or concave curved surface-shaped portion is formed by the front portion 31 and the rear portion 32 of the heaven gusset sheet 3. As a result, the content 69 transmitted from the spout 7 can be stored in the heaven gusset sheet 3, and the content 69 is excessively adhered to the outer surface of the front sheet 1 and the rear sheet 2 of the pouch container B1. It can be suppressed.

FIG. 9 shows a modified example of the pouch container package C1. In the figure, the same or similar elements as those in the above embodiment are designated by the same reference numerals as those in the above embodiment.

The curved portion 301 is interposed between the front top edge 34 and the front side edge 35, and has a convex curved shape. The curved portion 101 and the curved portion 301 substantially coincide with each other.

According to this modification, in addition to the action and effect of the pouch container / packaging body C1 described above, the connecting portion between the front side seal portion 51 and the front top seal portion 53 can be made into a gentle shape. The front side seal portion 51 and the rear side seal portion 52 are partially fixed to each other by providing the recess 351 and the recess 371, but the front side seal portion 51 is located at the top end portion in the z direction. (The outermost portion of the front top seal portion 53 in the x direction) is in a state where it can be separated from the rear side seal portion 52. Since this portion has a gentle convex curve shape due to the curved portion 101 and the curved portion 301, it is possible to suppress the purchaser from feeling pain.

The pouch container and packaging body according to the present invention is not limited to the above-described embodiment. The specific configuration of each part of the pouch container and package according to the present invention can be freely redesigned.
