The sheet 10 is made of a material that can be bent, does not break due to bending, and can be fixed. For example,
Natural materials such as paper and leather, corrugated cardboard, metal plates, thin metal foils, metal foil laminates, plastic films, two or more plastic laminate films, various textile fabrics and rubber or plastic laminates, these two types A laminated sheet or the like obtained by laminating the above can be used, and among these, a material that does not alter the content accommodated in the container and that does not deteriorate due to the content is appropriately selected.

Next, an example of a method for producing a continuous container using such a sheet 10 will be described with reference to FIGS. The dashed line and the two-dot chain line in FIG. 2 show how the sheet 10 is folded when viewed from the outside.
First, the side surface portion 31 is bent into a mountain centering on the one-dot chain line on the peripheral portion 23 of the bottom portion 21, and the adjacent side surface portions 31 are joined to form a side joining portion 35 as shown in FIG. 3. Thereafter, the side abutting portion 35 is fixed. Here, the side abutment portion 35 is fixed, but is not necessarily limited to this.
In order to increase the strength of the side abutting portions 35, it is desirable to fix them. Then, the end piece 45 is bent into a mountain about the dashed line.

Next, as shown in FIG.
3 is bent into a mountain centering on the one-dot chain line and into a valley centering on the two-dot chain line.

They may be fixed to each other.

The continuous container of this embodiment has a bottom surface 20.
Of the bottom surface 20 because there is no break in the peripheral portion 23
Is strong, and the side portion 31 is connected to the side reinforcing portion 33 without a break, and since the side joining portion 35 is covered with the side reinforcing portion 33, the strength of the side joining portion 35 is large. Since there is no break in the peripheral portion 41a of the ceiling surface and there is no break in the corner portion 41b of the ceiling surface, the strength of the peripheral portion 41a of the ceiling surface is large. Therefore, it is possible to reduce the leakage of the contents from the peripheral portion 23 of the bottom surface 20, the side contact portion 35, and the peripheral portion 41a of the ceiling surface. Further, since it is not necessary to use a material having higher strength as a material forming the sheet or to strictly control the quality of the container, the cost can be reduced.

Further, as shown in FIG. 7, a reinforcing member 34 having sufficient rigidity is fitted into a bag portion 34a surrounded by the side surface folding surfaces 33a, 33b, 33c, 33d so that the side abutting portions are formed. 35 can be further increased. Further, a string 36 is attached to the reinforcing member 34, and holes 37 are respectively formed in the side surface folded surfaces 33b and 33c.
Is formed, and the string 36 is led out from these holes 37 to facilitate handling when the container is suspended or transported.

In the continuous container of this embodiment, the end pieces 4
Although the case where the projecting piece 47 is larger than 5 has been described, the same can be applied to the case where the end piece 45 is larger than the projecting piece 47 as shown in FIG. Also, the projecting piece 4
The shapes of 7 and end piece 45 are not particularly limited as long as they can seal the container when they are overlapped. Further, a filling port and a discharging port can be provided on the ceiling surface 40 separately from the opening 50.

[0020]

[Effects of the Invention] As described above, the continuous container according to the present invention has a large strength at the peripheral edge of the bottom surface because there is no discontinuity at the peripheral portion of the bottom surface, and the side surface portion is connected to the side reinforcing portion without any discontinuity. And since the side abutment is covered with the side reinforcement, the strength of the side abutment is large,
Since there is no break in the peripheral portion of the ceiling surface and there is no break in the corner portion of the ceiling surface, the strength of the peripheral portion of the ceiling surface is large. Therefore, it is possible to reduce the leakage of the contents from the peripheral portion of the bottom surface, the side portion butting portion, and the peripheral portion of the ceiling surface. In addition, there is no need to use a material having higher strength as a material forming the sheet or to strictly control the quality of the container, thereby reducing costs.
