[Prior art]

 FIG. 2 is a development view showing a state before assembling the paper container according to one embodiment of the present invention. The conventional technique will be described with reference to FIG. In FIG. 2, reference numerals 1, 2, 3 and 4 respectively denote rectangular plates forming the container body. The rectangular plates 1, 2, 3, and 4 are arranged side by side on the left and right, and are connected to each other via fold lines. Further, on the right side of the rectangular plate 4, a seam allowance 5 is formed via a folding line. Below each of the square plates 1, 2, 3 and 4, bottom plate pieces 6, 7, 8 and 9 for forming a bottom plate are respectively formed via fold lines. A glue allowance 10 is also formed on the right side of the bottom plate piece 9.

On the upper side of the rectangular piece 1, a rectangular folding piece 11 that is folded inward in a V shape is formed through a folding line. A seam allowance 12 is formed on the upper side of the folding piece 11. On the upper side of the square plate 2 and on the right side of the folding piece 11, a square joining piece 13 is formed through the fold lines formed between the square plate 2 and the folding piece 11, respectively. A glue margin 14 is formed on the upper side of the joining piece 13. The margin 14 is slightly wider than the left margin 12. On the upper side of the rectangular plate 3 and on the right side of the joining piece 13, a rectangular folding piece 15 is formed via the fold line formed between the rectangular plate 3 and the joining piece 13. A seam allowance 16 is formed on the upper side of the folding piece 15. The folding pieces 11 and 15 and the seam allowances 12 and 16 have the same shape. On the upper side of the square plate 4 and on the right side of the folding piece 15, a square joining piece 17 is formed through the fold lines formed between the square plate 4 and the folding piece 15, respectively. A glue margin 18 is formed on the upper side of the joining piece 17. The joint pieces 13 and 17 and the glue allowances 14 and 18 have the same shape. A glue margin 19 is also formed on the right side of the joining piece 17. On the upper side of the seam allowance 19 and on the right side of the seam allowance 18, a seam allowance 20 is also formed.

The device shown in FIG. 2 is assembled as follows. First, after bending the whole into a rectangular tube, the longitudinal seam allowances 20, 19, 5 and 10 are adhered to the insides of the left ends of the seam allowance 12, the folding piece 11, the square plate 1 and the bottom plate piece 6, respectively. Next, the bottom plate pieces 6, 7, 8 and 9 are partially overlapped with each other and adhered to each other, thereby sealing the lower part of the container. Here, after injecting milk or the like into the container, the left and right folding pieces 11 and 15 are folded inward, and the glue allowances 12 and 16 are attached to the inside of the glue allowances 14 and 18 of the left and right joining pieces 13 and 17, respectively. At the same time, glue the glue margins 14 and 18 together and seal the top of the container. The product thus assembled is put on the sales route as a product. To take out the contents, the purchaser who purchased this product peels off the adhesive parts of the seam allowances 14 and 18 on the halves of the left and right joint pieces 13 and 17 and then the adhesive parts of the seam allowance 16. While pulling the folding piece 15 toward you. Then, the center of the folding piece 15 projects forward in a V shape to form an injection port, and the state shown in FIG. 4 is obtained. To transfer the contents of the container to a cup or the like in the state shown in FIG. 4 or swallow it by putting it on the mouth as it is, it is sufficient to tilt the container and lower the pouring mouth as shown in FIG. What is shown above is a conventional paper container.

[0005]

[Problems to be solved by the device]

 As clearly shown in FIG. 5, when the folding piece 15 is pulled out from the conventional paper container, a straight line is formed between the folding piece 15 and the rectangular plate 3, and the spout has a zigzag shape. Moreover, the spout is sharply squeezed forward from the line. Therefore, when the contents are flown out by tilting the container, the flow of the contents changes in a zigzag manner, and the flow of the line width suddenly concentrates and overflows into the thin spout. For this reason, the flow is extremely disturbed, and stable supply becomes difficult. Therefore, it is difficult to transfer a desired amount into a cup or the like or directly pour it into the human mouth, and the amount of the desired amount is overloaded or insufficient. Moreover, it may flow out and part of it may jump out of the cup or the like, or may be scattered on the face. Therefore, it is necessary to take care and balance the flow while slowly moving on. The problem to be solved by the present invention is to provide a paper container capable of smoothly flowing the contents out of the spout without disturbing the flow.

[0006]

[Means for Solving the Problems]

 Having solved the above-mentioned problems in the present invention, a paper container according to the present invention will be described. Before that, the structure of a conventional paper container will be described. The conventional one has four rectangular plates 1, 2, 3, and 4 forming a square tube, the bottom of the square tube is sealed, and folding pieces provided on two square plates 1.3 facing each other. 11 and 15 are folded inward in a V shape, and the upper sides of the joining pieces 13 and 17 provided on the remaining two rectangular plates 2 and 4 are respectively squeezed inward and the upper portions are folded in both directions. The upper portions of the pieces 11 and 15 are sandwiched from both sides, and the upper portions of both the folding pieces 11 and 15 and the joining pieces 13 and 17 are joined and bonded to each other. In the conventional paper container of the present invention, the folding line 21 for the spout is provided in the center of the folding piece 15 or in the vertical direction from the center of the folding piece 15 to the rectangular plate 3. . Paper containers come in various sizes. There are various materials and thicknesses. The pour spout fold line 21 may be provided only on the folding piece 15 or depending on the size, material, etc., or may be provided on the rectangular plate 3. When it is provided on the rectangular plate 3, its length is also determined according to the size and material of the container. The spout fold line 21 may be provided by pushing with a push die or may be provided by cutting with a notch die. Further, the spout fold line 21 may be simply displayed by printing or the like. It may be printed in a special color so as to have attention.
