The folded back plates 73 and 74 serve to connect the triangular sealing plate 44 to the sealing plate 60 and the side suture stand 20, respectively. The sealing plates 78 and 79 are connected to the folding back plates 73 and 74, respectively, and are also interconnected along the fold line 80.

FIG. 2 rotates the body wall 19 and the side suture 20 of FIG. 1 integrally with respect to the fold line 25 such that the inner side of the body wall 19 abuts against the inner side of the body wall 18. And the fold line 26 overlaps the fold line 24, the inner surface of the side suture stand 20 abuts the inner surface of the body wall 17 at a position proximate the fold line 24, The body wall 16 is rotated about the fold line 23 so that the inner surface is in contact with the inner surface of the body wall 17 to represent the container 100. The inner surface of the body wall 16 near the side end portion 21 contacts the outer surface of the side suture stand 20, and the side end portion 21 overlaps the fold line 26. The planar seal end 11 and the other parts attached to the seal end 13 also move in this manner, so that the container is in the state of FIG. 2. Then, the part where the inner surface of the body wall 16 and the outer surface of the side suture stand 20 are in contact with the side is sealed.

When the side sealing container 100 is completed, it is opened in a square as in FIG. 3, and the sealing end 13 is completed by a conventional method. The triangular seal plates 28 and 30 are then moved towards the center of the container with respect to the fold line 15. The folded back plates 33, 34 (37, 38) are rotated with respect to the fold lines 35, 36 (39, 40), respectively, so that their outer surfaces are in contact with the outer surfaces of the triangular sealing plates 28, 30. At the same time, the outer seal plates 27 and 29 are moved to face each other. The inner surface of the outer sealing plate 29 of the portion 31 located inward of the outer sealing plate 27 and the inner surface of the folded back plates 34 and 37 are positioned. Heat-sealing each part forms a structure in which liquid cannot pass through to the bottom.

3-6 illustrate a side closure container 100 in the form of a square capable of filling and sealing the contents. After the sealing end 13 is formed by the method described above, after the contents are filled in the container, the fold lines are folded to form the flat sealing end 11. When the triangular injection plate 42 is folded along the fold line 14 toward the upper center of the container, the triangular sealing plate 44 is simultaneously pressed to move along the horizontal fold line 14 to the center of the container.

At this time, the outer surfaces of the injection plates 68 and 69 are rotated with respect to the fold line 70 to be close to each other, and the outer surfaces of the sealing plates 78 and 79 are also rotated with respect to the fold line 80 and are close to each other. Done. The inner surface of the injection plate 69 and the inner surface of the sealing plate 78 are in contact with the sealing plate 62, and the inner surface of the injection plate 68 and the inner surface of the sealing plate 79 are in contact with the sealing plate 51. do.

As shown in FIG. 4, each part of the container is positioned at an angle with respect to the end of the body 12. In the embodiment of the present invention, the injection plates 68 and 69 and the sealing plates 78 and 79 are basically sealed, and the sealing plates 51 and 62 are injected plates 68 and 69, respectively. ) And the upper and lower ends of the sealing plates 78 and 79 to be positioned between the various layers so that no liquid can pass therethrough. In a preferred embodiment, the sealing is performed by an ultrasonic sealer. According to this method, not only the complete sealing which can pass through the liquid at all but also the opening can be easily opened by the user.

When the sealing as described above is completed, the inner surface of the fixing piece 54 is heated so that the fixing piece 54 is heat-sealed to an end portion of the sealing plate 60 which is abutted along the fold line 14. (See Figure 6.) Thus, the container is completed by sealing the sealing end part 13, putting a content into a container, closing the flat sealing end part 11, and sealing. The ultrasonic bonding portion forms a center suture 82, and the fixing piece 54 forms a heat-sealed outer suture 84. Thereafter, the perforation lines 57 and 58 may be positioned between the center suture stand 82 and the outer suture stand 84.

If the consumer wants to take out the contents of the container, raise the tip 86 on the opening piece 53 and tear off the container along the perforation lines 57 and 58 as shown in FIG. As in FIG. 8, the container can be opened when the opening piece 53 is removed. 9 and 10, the center suture 82 is erected vertically upward, and the user presses his thumb against the ends of the fold lines 23 and 24, and the folded back plate 63 64 moves upwards, whereby the ends of the sealing plates 47, 60 on the inlet side rotate around the open auxiliary fold lines 49, 61, and thus the auxiliary fold lines ( 49) 61 are pressed towards the fold line 23 and the fold line 24, ie towards the end 21 and the fold line 25, respectively. In this way, the triangular injection port 42 is pushed out of the closed position by the action of pressing with the thumb to the open position as shown in FIG. Returning the triangular inlet 42 to its original position causes the container to be resealed, which is illustrated in FIG.
