The front wall 34, the rear wall, the side wall 35, and the trunk connecting wall 36 are all rectangular.
It has the shape of a shape.

The upper end 32 has a top wall 37, a front wall 38 connecting the top wall 37 and the front wall 34, a rear wall (not shown) connecting the top wall 37 and the rear wall, Two side walls 39 (only one side wall 39 is shown in the drawing) connecting the top wall 37 and each side wall 35, and four connections connecting the top wall 37 and each body connecting wall 36. The wall 40 (one of the connecting walls 40 in the figure)
Just show. ). Each of the front wall 38, the rear wall, and the side wall 39 has a trapezoidal shape with an upper bottom placed down, and the connecting wall 40 has a triangular shape with one apex placed on the top wall 37. . Reference numeral 46 denotes a seal formed in the center of the top wall 37, and 47 denotes an ear.
Is fused to the side wall 39.

The lower end connects a bottom wall, a front wall connecting the bottom wall to the front wall 34, a rear wall connecting the bottom wall to the rear wall, and a bottom wall to each side wall 35. It consists of two side walls, and four connecting walls connecting the bottom wall and each body connecting wall 36.

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 laminated body having flexibility, and has a paper base (not shown), an outermost layer (not shown) 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.

By the way, a spout is formed at a predetermined position on the top wall 37, for example, substantially at the center of the position close to the boundary line L1 between the top wall 37 and the front wall 38. Is folded back along the outline of the spout and a guide 72 is provided on the top wall, and a guide 71 is provided on the front wall of the packaging material.
Are fixedly formed. That is, even if the spout is punched, the punched portion does not separate from the packaging material and remains on the front wall and the top wall as guides 71 and 72, so that the divided shape of the punching is as shown in FIG. The front wall of the outlet has a trapezoidal shape 71 to secure a large area so that the lips can be given a sufficient sense of stability during drinking, and the left and right sides of the spout have a remaining triangular shape 72.

A pull tab 52 is attached from the front side of the packaging material so as to cover the inside of the spout. The pull tab 52 is made of 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 a polyethylene resin coated on the back surface of the barrier layer. And the like. The pull tab 52 has an area larger than the spout 51 and, when attached to the packaging material, the top wall 37.
And a vertical portion 52b which covers the periphery of the spout 51 so as to prevent contamination, and a vertical portion 52a which is gripped when the pull tab 52 is peeled off. Further, an inner tape 77 is attached from the back side of the packaging material on the top wall 37, and is sealed with the pull tab 75 and the periphery of the spout 51.

Referring to FIG. 6, the process of forming the spout and fixing the pull tab in the container packaging material will be briefly described with reference to only the essential parts. In the first steps 71 and 72, punching is performed from the back surface of the packaging material by a punch 81 in order to form a spout of a desired shape in the container packaging material 83. At this time, the punched portion 82 does not separate from the packaging material and is poured as it is. It is folded back along the outline of the exit (84). In the second step 73, the punched portion 86, which is folded back along the outline of the spout, is pressure-bonded from both sides of the packaging material with the tools 85 and 87, and is fixed to the packaging material by applying heat. In the third step 74, the pull tab 52 is provided from the front side of the packaging material to the spout formed in the above step, and the inner tape 77 is provided from the back side of the packaging material. The pull tab and the inner tape adhere to each other to form an outlet for the packaging material.

Therefore, as shown in FIG. 3, the inner tape can be broken by pulling the pull tab 75 from the packaging container body 30, the spout 51 can be opened, and the packaging container 29 can be opened. Then, the lips can be applied to the opened spout 51 to directly drink the liquid food. In this case, the spout guide 71
And 72 surround the spout, so that the mouth of the spout can be improved. Moreover, it is easy to drink liquid food.

Further, by tilting the packaging container 29, the liquid food can be poured from a spout 51 into a container such as a glass (not shown).

The present invention is not limited to the above-described embodiment. For example, FIG. 4 shows that a spout guide can be made triangular on the front wall of the container to improve the apparent sharpness of the container. A rounded triangle will give a slightly reduced sharpness. In FIG. 5, the spout guide is bent several times around the spout to increase the height of the projection from the top surface of the container, thereby increasing the lip feeling given to the lips. As described above, various modifications can be made based on the gist of the present invention, and they are not excluded from the scope of the present invention.

[0021]

As described in detail above, according to the present invention, the packaging container has the thick portion without the lid surrounding the spout and is welded to the top wall and the front wall. A spout guide is provided, and a pull tab is attached to the spout so as to cover the spout from the front side of the packaging material forming the top wall.

In this case, the spout portion is surrounded by the spout guide, so that the mouthfeel of the spout portion can be improved. In addition, since the cutting member of the top wall of the packaging material is folded back around the partially uncut portion as a spout guide on the top wall of the packaging material and the front wall of the packaging material, unnecessary pieces after punching are unnecessary. Since the dust collecting device is unnecessary, a low-cost and easy-to-drink packaging container can be provided.
