Next, the order of forming the brick type paper container 1 shown in FIG. 1 from the blank plate 5 and the spout 6 shown in FIG. 2 will be described. First, a double-width portion of the hemming area A from the right end of the blank plate 5 is skived (cut) by half the thickness of the packaging material from the front side, and at the same time, a reverse ruled line α is formed, and the reverse ruled line α is folded back and bonded. To keep the thickness substantially the same as the original thickness. Next, the blank plate 5 is folded at the ruled lines a, b, c, and d, and the skive hemming portion of the bonding side panel 51 is joined to the back side of the bonding region B in the bonding side panel 41, and the two are combined. The both ends of the blank plate 5 are heat-sealed and adhered in a state where the size is the same as that of the wide side panel 11, thereby forming a square tubular body. By performing the end face treatment in this manner, the cut end face of the packaging material is not exposed to the inside of the paper container, so that moisture does not travel along the paperboard layer to weaken the packaging material or cause liquid leakage.

After the body is formed as described above, the bonding lid panel 4 of the upper closing panel P4 is held in a state where the body is raised.
The spout 6 is inserted from the inside into the mounting hole 4 provided in 2, and the front side of the flange portion 62 of the spout 6 is heat-sealed to the inner peripheral surface of the mounting hole 4 by ultrasonic sealing.
In this case, the two orthogonal sides 62a and 62b of the flange portion 62 of the spout 6 are positioned along the ruled lines m and c, respectively. Therefore, the opening area 6 of the spout 6
The two sides 61a, 61b constituting the tip of the first one are substantially parallel to the ruled lines m, c defining the bonding lid panel 42. Then, after attaching the spout 6 in this way, it is folded and transported to the filling step.

In the subsequent filling step, first, the folded blank plate 5 is raised into a rectangular tube shape, and the bottom closed panels T1 to T
5 form a bottom closure. That is, the bottom panels 14 and the bonded bottom panels 44 and 54 are simultaneously bent while the folding panels 25 and 35 are bent outward, and the small folding panels 26 and 26 are folded into the folding panel 25, and the small folding panels 36 and 36 are folded into the folding panel 35. 36 are overlapped to form a triangular overlapping portion to make the bottom of the body flat, and then the inner surfaces of the outer rib panel 15 and the bonding rib panels 45 and 55, and the inner surfaces of the inner rib panels 27 and 27 and the inner surface. After the inner surfaces of the rib panels 37, 37 are bonded to each other to form a linear overlapping portion, the linear overlapping portion is folded down, and the triangular overlapping portion is bent downward and bonded to the bottom.

After the bottom closure is formed, the contents are filled with liquid, and then the top closure is formed by the top closure panels P1 to P5. That is, simultaneously with folding the folding panels 22 and 32 outward, the lid panel 12 and the bonding lid panels 42 and 52 are also folded inward, and the small folding panels 23 and 23 are formed on the folding panel 22, and the small folding panels 33 and 23 are formed on the folding panel 32. The upper portion of the body is flattened by superimposing the triangular portions 33 to form a triangular overlap portion, and then the inner surfaces of the outer rib panel 13 and the bonding rib panels 43 and 53, the inner surfaces of the inner rib panels 24 and 24, and the inner rib panel. 3
4 and 34 are bonded to each other to form a linear overlapped portion, and the straight overlapped portion is turned to the side opposite to the spout 6, and the triangular overlapped portions are respectively bent downward to form narrow side panels 21 and 31. To complete the assembly.

In the above-described assembling procedure, an example was described in which the spout 6 was attached before the material was conveyed to the filling step. May be attached. That is, the folding blank plate without the spout 6 is conveyed to the filling step, raised into a rectangular tube to form a bottom closure, and then the spout 6 is attached, and then the contents are filled and the top is closed. The formation of the portion is performed.

In the brick-type paper container 1 formed as described above, the flat spout 6 is adhered to the inner surface of the paper container main body 2 by the flange portion 62 which is one step lower than the opening area 61 of the paper container. It is in a state where it hardly protrudes from the container body 2 and does not hinder handling. Also, the spout 6 is in a state where the two sides 61a and 61b forming the tip of the opening area 61 are substantially parallel to the two sides of the corner with respect to the mounting hole 4 close to the corner at the top surface 3. , And is in a state of being attached to the paper container body 2.

When removing the contents, the pull ring 65 is pulled to break the connecting portion 66, and the pull ring 65 is further pulled to separate the hinge lid 63 from the thin portion q. In this case, the force concentrates on the thin-walled portion q located at the tip of the mountain-shaped portion, and the fracture starts from here. Then, when the hinge lid 63 is sufficiently lifted, FIG.
As shown in FIG. 7, the locking hook 68 is locked to the projection 69, and the hinge lid 63 is kept in a stable open state. Also,
When this is pressed to close the hinge lid 63, the protrusion 71 at the tip of the pull ring is locked to the peripheral edge, the hinge lid 63 does not drop significantly, and burrs generated by separating the thin part q interfere with each other. Thus, the hinge lid 63 is not easily opened.

When the contents are poured by tilting the paper container 1 with the hinge lid 63 of the spout 6 opened, the contents are easy to pour to the end because the spout 6 is close to the corner. . Therefore, the contents are taken out with little remaining in the paper container.

Although the present invention has been described in detail based on one embodiment, the plastic spout used in the present invention may be of any shape other than the above embodiment. it can. For example, the shape of the hinge-lid in those hinge-lid type partitioned by such thin portions of the above embodiment is good casting even elliptical be circular.

[0028]

As described above, the brick type paper container of the present invention has a construction in which the plastic spout is mounted close to the corner on the top surface of the paper container body, so that the contents can be taken out. In spite of attaching a convenient spout, it is possible to pour out the contents without leaving the contents. In addition, the opening
