3 and four connecting walls 44 connecting the bottom wall and each body connecting wall 36.

The packaging container body 10 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 10 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 guide 71 is attached by fusion at a predetermined position on the top wall 12, for example, substantially at the center near the boundary L1 between the top wall 12 and the front wall 38. The spout guide 71 has a “U” -shaped thick-walled portion shape and a resin molded on the top wall is adhered thereto. An opening 52 formed of, for example, a “U” -shaped perforation is provided at a predetermined position in the “U” -shaped region surrounded by the spout guide 71. Furthermore, a circular pre-laminar hole having a diameter of, for example, 6 mm is formed in a portion of the inner area of the opening portion adjacent to the boundary line L1.

Here, a method of manufacturing and attaching the spout guide 71 will be described. For example, since a spout guide is formed by a device (not shown) in advance, the spout guide is attached to a predetermined position after positioning the container body. That is, it is common to stop the container main body on the conveyor, take out the container main body from the conveyor once, fix the spout guide, and then set the container main body on the conveyor again. In the packaging container according to the embodiment of the present invention, the opening lever is provided so as to cover the spout, and a part of the opening lever is fixed to a part of the spout guide at the joint 76. ing. Therefore, the normal spout guide 7
Since 1 and the opening lever 72 are integrally molded with resin,
By fixing the exit guide 71 to a predetermined position on the top wall of the packaging material, the opening lever 72 is also automatically attached to the container.

Next, a method of taking out the contents from the packaging container will be described. FIG. 5 is a cross-sectional view showing a state in which the opening lever of the packaging container according to the embodiment of the present invention is inserted into the pre-laminated hole and fitted. As shown in the figure, when the back surface of the piercing portion 75 of the spout portion 71 of the spout guide 71 with the opening lever 72, which is fixed to the packaging container top wall 12 and integrally formed by injection molding, is pushed down with a finger, the spouting guide 72 is moved. It is separated from 71 and pressed onto the container top surface 12. At this time, the piercing portion 75 is pierced into the pre-laminated hole on the container top surface 12. In addition, since the piercing portion 75 is provided with a detent, it does not easily come off once piercing. The opening lever is provided so as to cover the spout portion, and a part of the opening lever is fixed to a portion of the spout guide at the joint portion 76. When separated and pressed onto the container top surface 12, the joint 76 is sheared. That is,
The joint portion 76 is fixed with a force enough to cause shearing when the back surface of the piercing portion 75 is pressed down with a finger. Also serves as.

FIG. 6 is a cross-sectional view showing a state in which the opening lever 72 pierced and fitted into the spout (pre-laminated hole) of the packaging container according to the embodiment of the present invention is pulled up and opened. FIG. 7 is a cross-sectional view showing a state where the opening lever 72 pierced and fitted into the spout port (pre-laminated hole) of the packaging container according to the embodiment of the present invention is lifted up and the opening is completed. Then, the lips can be applied to the spout guide 71 to directly drink the liquid food. in this case,
Since the spout section is surrounded by the spout guide 71,
The mouth of the spout is easy to drink.

Further, by tilting the packaging container 10, the liquid food can be poured from the spout 51 into a container such as a glass (not shown). By arranging the spout outlet guide 71 at this time, the flow of the inner solution can be easily collected and poured when the pouring is performed.

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. In the present embodiment, the spout 51
Is formed so as to be opened after piercing by forming a pre-laminated hole in the spout portion, but may be a perforated portion instead of the pre-laminated hole, but at this time the piercing portion may be pierced. The perforation breaking strength needs to be weaker than the breaking strength of the spout 51. In the present embodiment, the spout guide 71 has a “U” along a front edge and a side edge of the spout 51.
Although it is formed in the shape of a letter, for example, it may be oval,
1 may be formed in a closed loop along the inner peripheral edge.
At that time, the spout 51 itself is formed as an oval or a closed loop so as to adapt to the spout guide 71 as necessary.

The outlet guide 71 and the opening lever 7
2 is also a dust-proof measure for the spout 51, but when more reliable dust-proofing is required, the entire area is joined instead of the joint part 76 in consideration of the shape that can be pushed off by the force of a finger. I just need. Further, the lifting section 73 and the outlet guide 7
If a gap between the opening lever 72 and the opening lever 72 is pressed down by a soft member such as a tape or a sponge in a manner not shown, a dustproof structure that does not hinder the movement of the opening lever 72 can be obtained.
