The packaging container body 30 is formed by molding a packaging material. For this purpose, a fold is formed in the packaging material in advance, and the packaging material is bent along the fold to form a prototype container. Subsequently, a predetermined molding process is performed on the prototype container to form a packaging container body 30 having a final shape. The packaging material is made of a laminate having flexibility, and is formed of a paper base (not shown), an outermost layer made of polyethylene resin or the like coated on the surface of the paper base, and a back surface of the paper base. A barrier layer (not shown) having a gas barrier property and an innermost layer (not shown) made of polyethylene resin or the like coated on the back surface of the barrier layer.

A spout 51 formed of a punch hole is formed at a predetermined position on the top wall 37, for example, near the front wall 38. The pull tab 52 having a gas barrier property covers the spout 51 and the spout 5.
1 and the portion where the lips contact the front wall 38 during drinking. The pull tab 52 is made of, for example, an aluminum foil (foil), and has a barrier layer having a gas barrier property, an outermost layer made of polyethylene resin or the like coated on the surface of the barrier layer, and is coated on the back surface of the barrier layer. It has an innermost layer made of polyethylene resin or the like. Then, an inner tape (not shown) is provided in the packaging container main body 30,
The pull tab 52 and the periphery of the spout 51 are sealed.

When drinking, as shown in FIG.
Before the liquid food 55 is poured out of the packaging container, the vicinity of the top wall 37 of the front wall 38 of the packaging container is pushed in along with a preformed crease, so that the vicinity of the top wall of the front wall and the top wall are separated. Keep the angle acute. Then, the inner tape is broken by peeling the pull tab 52 from the packaging container body 30, and the spout 51 is opened. Further, by tilting the packaging container 29, as shown in FIG. 4, the liquid food 55 can be poured from the spout 51 into a container such as a glass (not shown).

As described above, since the angle between the vicinity of the top wall of the front wall and the top wall is acute, when the liquid food 55 is poured into the container, the liquid food 55 that has exited from the spout 51 is transferred to the top wall 37.
It is hard to spread left and right on the upper side, and forms a narrow flow on the tangent line 61 between the top wall 37 and the front wall 38. Therefore, the liquid food 55 can be poured smoothly into the container, and the liquid food 55 does not spill out of the container. Then, in the vicinity of the spout 51, the inclination of the front wall 38 becomes steep, and the angle formed by the top wall 37 and the front wall 38 becomes small, so that the liquid food 55 flows further along the front walls 38, 34. There is no.

It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified based on the gist of the present invention, and they are not excluded from the scope of the present invention. For example, although a description has been given of a polyhedral container, the present invention can be similarly applied to a brick container.

Keep it. Then, the inner tape is broken by peeling the pull tab 52 from the packaging container body 30, and the spout 51 is opened. As described above, since the angle between the upper surface of the front wall and the top wall is acute, when the liquid food 55 is poured into the container, the liquid food 55 that has exited from the spout 51 moves right and left on the top wall 37. Difficult to spread, top wall 3
A narrow flow is formed on a tangent line 61 between 7 and the front wall 38. Therefore, the liquid food 55 can be poured smoothly into the container, and the liquid food 55 does not spill out of the container. Then, in the vicinity of the spout 51, the inclination of the front wall 38 becomes steep, and the angle formed by the top wall 37 and the front wall 38 becomes small, so that the liquid food 55 flows further along the front walls 38, 34. There is no. In addition, the feel when the lips are applied to the periphery of the spout 51 and the front wall 38 is good, and the liquid food 55 can be easily drunk directly.
