However, if the shape-retaining parts 17 and 18 are not provided, the The gas supplied into the liquid storage container 1 is immediately sent to the lower part, and the upper part is not easily expanded, so that the liquid storage container 1 expands unevenly. If the liquid container 1 expands unevenly, it becomes impossible to fill the bag body 3 with a desired amount of liquid. According to the present embodiment, after the liquid container 1 is folded into an accordion shape, the upper and lower parts are fixed by the pair of shape-retaining parts 17 and 18, whereby the liquid container is sequentially transported from the upper part to the lower part and supplied to the liquid container. The gas in the container 1 can thereby inflate the bag body 3 of the liquid container 1 gradually and uniformly as a whole from top to bottom. Thereby, a desired amount of liquid can be filled in the bag body 3 . However, the pair of shape retaining portions 17 and 18 may not necessarily be provided.

As described above, according to this embodiment, the liquid container 1 inserted into the rectangular box-shaped outer container 5 through the opening 5 a can be easily and surely expanded according to the inner surface shape of the outer container 5 . Therefore, the liquid container 1 can be filled with liquid by effectively utilizing the interior of the liquid container 1 that has expanded according to the shape of the inner surface of the outer container 5 .

As described above, the combination of the outer container 5 and the liquid container 1 is obtained. After that, the inflation jig is removed from the spout 40 , a content liquid filling machine (not shown) is installed in the spout 40 , and the content liquid is filled into the liquid container 1 from the content liquid filling machine.

After the content liquid is filled into the liquid container 1 , a spout cap is attached to the spout 40 .

Next, the holder 80 is removed from the spout 40 . At this time, the holder 80 is detached from the spout 40 in the reverse order of the above-mentioned procedure to be attached to the spout 40 .

Since the inner diameter of the opening 5 a of the outer container 5 is larger than the outer diameter of the spout flange 42 of the spout 40 , when the holder 80 is removed from the spout 40 , the spout 40 drops to the outside through the opening 5 a into container 5.

Next, the opening cap 5A is attached to the opening 5a of the outer container 5, and the outer container 5 is completely sealed.

Next, the outer container 5 with the opening cap 5A attached to the opening 5a is conveyed to the conveyance destination end.

The liquid distribution nozzle 60 inserted into the spout upper member 70 extends through the through hole 45 of the spout 40 and into the bag body 3 of the liquid container 1 .

Next, the content liquid in the liquid container 1 is discharged to the outside. At this time, the liquid dispensing nozzle 60 is connected to the dispenser through the connecting pipe 63 .

Next, nitrogen gas is supplied into the spout body 41 of the spout 40 from a pressurized gas source (not shown), and then the nitrogen gas enters between the outer container 5 and the bag body 3 of the liquid container 1 through the opening 44 space between. Next, the bag body 3 is pressed by nitrogen gas from the outside, the content liquid in the bag body 3 enters the liquid distribution nozzle 60 , and the content liquid in the liquid distribution nozzle 60 is then discharged from the connecting pipe 63 to the dispenser side. Alternatively, a suction pump (not shown) may be connected to the spout 40, and discharge by the suction pump may be performed. At this time, although the bag body 3 shrinks as it is discharged, since the outside of the bag body 3 maintains the atmospheric pressure, the outer container 5 is not deformed even if it is not a pressure-resistant container.

Among them, in the above-mentioned embodiment, after inserting the liquid container 1 into the outer container 5, nitrogen gas or clean dry gas is supplied into the liquid container 1, thereby expanding the liquid container 1 in the outer container 5. For example, but not limited to this, after inserting the liquid container 1 into the outer container 5, the liquid container 1 may be filled with the content liquid by the content liquid filling machine immediately, and the liquid container 1 may be expanded while the liquid container 1 is inflated. The liquid container 1 is filled with the content liquid.

At this time, when the liquid storage container 1 in the outer container 5 is filled with the content liquid, first, the content liquid is sent under the liquid storage container 1 by its own weight to form the rectangular bottom surface 30 of the bag body 3 and Partially expands from below. If the lower shape-retaining portion 18 is provided in accordance with the expansion of the lower portion, it will be broken. The bag body 3 of the liquid container 1 folded along the longitudinal fold line as shown above is gradually expanded from the lower part toward the upper part, thereby also forming the rectangular upper surface 35 of the bag body 3 .

When a predetermined amount of the content liquid is filled in the bag body 3 , the bottom surface 30 of the bag body 3 maintains a rectangular shape and falls directly to abut against the bottom of the outer container 5 . After that, the bag body 3 is inflated between the upper surface 35 and the bottom surface 30 while maintaining the shapes of the rectangular bottom surface 30 and the rectangular upper surface 35 .

At this time, the bag body 3 is tied to the rectangular upper surface 35 and the rectangular The bag body 3 itself expands into a rectangular parallelepiped along the inner surface of the rectangular box-shaped outer container 5 between the bottom surfaces 30 of It is arranged in the box-shaped outer container 5 .

As described above, according to the present embodiment, the liquid container 1 inserted into the rectangular box-shaped outer container 5 through the opening 5a can be easily and surely expanded according to the shape of the inner surface of the outer container 5, Furthermore, the liquid storage container 1 can be filled with the content liquid by effectively utilizing the inside of the liquid storage container 1 which expands according to the shape of the inner surface of the outer container 1 . In this case, in particular, the bag body 3 has a rectangular bottom surface 30 and a rectangular upper surface 35 for the content liquid, and the liquid container 1 can be filled with the content liquid while the liquid container 1 is surely expanded.
