Here, FIG. 1 to FIG. 21 are diagrams showing an embodiment of the present invention.

  First, the liquid storage container 1 will be described. As shown in FIGS. 1 and 2, a first base material portion 2A, a second base material portion 2B, and a gusset portion 2C are prepared. Among these, first, the first base material portion 2A and the second base material portion 2C are prepared. The base material part 2B is overlapped. Next, a pair of gusset portions 2C having a folded portion 2C1 folded in two are inserted between the first base material portion 2A and the second base material portion 2B, and joined to form the joint portion 10. Thus, the bag body 3 is obtained. The liquid storage container 1 includes the bag body 3 and a spout 40 disposed on the upper edge 3a of the bag body 3 and heat-sealed between the first base material portion 2A and the second base material portion 2B. I have.

  Here, the “first base material portion 2A” and the “second base material portion 2B” are made of separate films, respectively, and may be combined with each other to produce the bag body 3, and a single film is folded. You may produce the bag main body which has the 1st base material part 2A and the 2nd base material part 2B by folding.

  Further, in this specification, “upper”, “upper edge”, “bottom part”, and “bottom edge” mean “upper”, “upper edge”, and “bottom part” when the liquid storage container 1 is arranged with the spout 40 facing upward. "" The bottom edge ". Furthermore, “both sides” refers to both sides in the width direction of the first base material portion 2A and the second base material portion 2B which are orthogonal to a straight line passing through the spout 40 connecting the top and bottom of the bag body 3.

  In this case, the bag body 3 has a top edge 3a, a bottom edge 3b, and a side edge 3c and has a rectangular shape (see FIG. 1).

  Further, the joint 10 is formed by joining the upper portion 3A of the bag body 3 that is opened and the bottom edge joint 10b that is formed by joining the bottom portion 3B of the bag body 3 that is opened. And have. Further, the first base portion 2A and the pair of gusset portions 2C are joined to form a side edge joint portion 10C, and the second base portion 2B and the pair of gusset portions 2C are also joined. The side edge joint portion 10C is formed. In the embodiment shown in FIGS. 1 and 2, since the first base material portion 2A and the second base material portion 2B will be described as being formed of separate films, the bottom 3B of the bag body 3 is opened. However, when the bag body 3 having the first base material portion 2A and the second base material portion 2B is produced by folding one film, the bottom portion 3B of the bag body 3 is opened. Instead, the folded portion may be joined to form the bottom edge joined portion 10b.

  Among these, the upper edge joint portion 10a is composed of an upper edge main body joint portion 10a1 formed by joining the first base material portion 2A and the second base material portion 2B, the first base material portion 2A, the gusset portion 2C, and It has the upper edge gusset part joint part 10a2 formed by joining the second base material part 2B and the gusset part 2C.

  Further, the bottom edge joint portion 10b includes a bottom edge main body joint portion 10b1 formed by joining the first base material portion 2A and the second base material portion 2B, the first base material portion 2A, the gusset portion 2C, and the second base material portion 2B.

  In this way, the liquid storage container 1 configured in a gusset shape is configured by the bag body 3 and the spout 40 attached to the upper edge 3a of the bag body 3. Note that the spout 40 does not necessarily have to be attached to the upper edge 3a of the bag body 3, and may be attached to the surface of the first base member 2A or the surface of the second base member 2B.

  The gusset-shaped liquid storage container 1 having such a configuration is folded compactly as follows, and is inserted into the outer container 5 having a large box shape, which will be described later, from the opening 5a.

Next, the folding form of the liquid storage container 1 will be described with reference to FIGS.
First, as shown in FIG. 3, a gusset-shaped liquid storage container 1 is prepared.

Next, as shown in FIG. 4, a rectangular bottom surface 30 is formed on the bottom 3 </ b> B of the bag body 3.
In this case, the bottom portion 3B of the bag body 3 is first lifted, and the first base portion 2A side of the bottom portion 3B of the bag body 3 is bent inward via the folding line 2A1, and similarly the second base portion. The fold line 2B1 is bent inward on the 2B side. In this way, a rectangular bottom surface 30 is formed on the bottom portion 3B of the bag body 3, and the bottom surface 30 includes the bottom edge joint portion 10b described above.

  Next, on the back side of the rectangular bottom surface 30, the gusset portion 2C is folded into a triangular shape to form a triangular shape 2C3 having a triangular shape.

  In FIG. 4, the bottom surface 30 includes a first base material portion 2 </ b> A and a second base material portion 2 </ b> B, and the first base material portion 2 </ b> A is located above the bottom edge joint portion 10 b in the rectangular bottom surface 30.

  Further, a gusset that is folded between the first base material portion 2A and the second base material portion 2B on the back side of the first base material portion 2A and the second base material portion 2B constituting the bottom surface 30 of the bag body. An edge 2C2 of the part 2C appears (see FIG. 4).

  Next, as shown in FIG. 5, along the bottom edge joint portion 10b on the bottom surface 30, at least of the bottom edge joint portion 10b, between the first base material portion 2A and the gusset portion 2C and the second base material. A first fixing tape 31 is provided to fix the bottom edge gusset part joints 10b2 between the part 2B and the gusset part 2C. However, the first fixing tape 31 may extend along the bottom edge joint 10b from one end to the other end of the bottom edge joint 10b in the bottom surface 30.

  In this way, by fixing the bottom edge gusset portion joint 10b2 with the first fixing tape 31, the rectangular shape of the rectangular bottom surface 30 can be reliably maintained.

  Next, the bottom surface 30 and the pair of gusset portions 2C arranged on both sides of the bottom surface 30 are fixed by a third fixing tape (third fixing means) 32, and the bottom surface 30 and a pair of the gusset portions arranged on both sides of the bottom surface 30 are fixed. The gusset portion 2C is firmly fixed. As described above, the gusset portion 2C is folded into the back surface of the first base material portion 2A and the second base material portion 2B constituting the bottom surface 30 to form the triangular portion 2C3. By fixing the space between the bottom surface 30 and the pair of gusset portions 2C disposed on both sides of the bottom surface 30 by the inflating of the bag body 3 of the liquid storage container 1 and filling the interior of the bag body 3 with liquid The liquid is prevented from entering the triangular triangular portion 2C3 formed by folding the gusset portion 2C.

  Next, the liquid container 1 is repeatedly pulled to bring the bottom surface 30 downward (see FIG. 6).

  Next, as shown in FIG. 7, a rectangular upper surface 35 is formed on the upper portion 3 </ b> A of the bag body 3.

  In this case, first, the upper part 3A of the bag body 3 is lifted, and the first base part 2A side of the upper part 3A of the bag body 3 is bent inward via the folding line 2A2, and similarly the second base part 2B. Bend the folding line 2B2 inward. In this way, a rectangular upper surface 35 is formed on the upper portion 3A of the bag body 3, and the upper surface 35 includes the upper edge joint portion 10b described above.

  Next, on the back side of the rectangular upper surface 35, the gusset portion 2C is folded into a triangular shape to form a triangular shape 2C3 having a triangular shape.

  In FIG. 7, the upper surface 35 includes a first base material portion 2 </ b> A and a second base material portion 2 </ b> B, and the first base material portion 2 </ b> A is positioned on the upper side of the upper edge joint portion 10 a of the rectangular upper surface 35. The second base material portion 2B is located on the rectangular upper surface 35 below the upper edge joint portion 10a.

  Further, a gusset portion folded between the first base material portion 2A and the second base material portion 2B on the back side of the first base material portion 2A and the second base material portion 2B constituting the upper surface 35 of the bag body. An edge 2C2 of 2C appears (see FIG. 7).

  Next, as shown in FIG. 8, along the upper edge joint portion 10a on the upper surface 35, at least of the upper edge joint portion 10a, between the first base material portion 2A and the gusset portion 2C and the second base material portion. A second fixing tape 36 is provided to fix the upper edge gusset part joints 10a2 between 2B and the gusset part 2C. However, the second fixing tape 36 may extend along the upper edge joint portion 10a from one end of the upper edge joint portion 10b to the other end of the upper surface 35.

  Thus, by fixing the upper edge gusset part joint 10a2 with the second fixing tape 36, the rectangular shape of the rectangular upper surface 35 can be reliably maintained.

  Next, the upper surface 35 and the pair of gusset portions 2C arranged on both sides of the upper surface 35 are fixed by a fourth fixing tape (fourth fixing means) 37, and the upper surface 35 and a pair of gusset portions arranged on both sides of the upper surface 35 are fixed. The gusset portion 2C is firmly fixed. As described above, the gusset portion 2C is folded between the first base material portion 2A and the second base material portion 2B constituting the upper surface 35 to form a triangular portion 2C3. When the upper surface 35 and a pair of gusset portions 2C disposed on both sides of the upper surface 35 are fixed by 37, the bag body 3 of the liquid storage container 1 is inflated and then filled with the liquid. In addition, the liquid does not enter the triangular triangular portion 2C3 formed by folding the gusset portion 2C.

  In this way, by fixing the rectangular bottom surface 30 of the bag body 3 with the first fixing tape 31 and the third fixing tape 32, the bottom surface 30 can reliably maintain its rectangular shape. Further, by fixing the rectangular upper surface 35 with the second fixing tape 36 and the fourth fixing tape 37, the upper surface 35 can reliably maintain its rectangular shape. The first fixing tape 31, the second fixing tape 36, the third fixing tape 32, and the fourth fixing tape 37 function as first fixing means, second fixing means, third fixing means, and fourth fixing means, respectively. However, the present invention is not limited to this, and an adhesive or an adhesive may be used as the first fixing means, the second fixing means, the third fixing means, and the fourth fixing means.

  For this reason, when the liquid storage container 1 is folded compactly as described later and inserted into the rectangular parallelepiped box-shaped exterior container 5 from the opening 5a to inflate the liquid storage container 1, the outer shape of the liquid storage container 1 is expanded. Along with the inner surface of the rectangular parallelepiped box-shaped outer container 5, it can be inflated in conformity with the inner surface shape. The exterior container 5 is not limited to a rectangular parallelepiped box-shaped exterior container, and a cubic box-shaped exterior container may be used.

  Next, as shown in FIG. 9, in the liquid storage container 1, the upper edge joint portion 10a and the bottom edge joint portion 10b are overlapped and folded into two with the upper edge joint portion 10a and the bottom edge joint portion 10b as crease lines. .

  Thereafter, the folded liquid storage container 1 is folded in a bellows shape along a plurality of longitudinal folding lines 15 (see FIGS. 10 and 11). The liquid storage container 1 does not necessarily have to be folded in a bellows shape, but when the liquid storage container 1 is inserted into the outer container 5 by folding the liquid storage container 1 in a bellows shape, the liquid storage container 1 can be easily folded in the outer container 5. Can be expanded. At this time, when the liquid storage container 1 is folded at the center line in the width direction orthogonal to the straight line passing through the spout 40 connecting the upper and lower portions of the bag body 3, the liquid storage container 1 stores the liquid by the vertical folding lines 15 on the left and right sides, respectively. More preferably, the container is folded into a symmetrical bellows. That is, as shown in FIG. 11, mountain folds and valleys of longitudinal folding lines 15 formed on both sides across a center line in the width direction perpendicular to the straight line passing through the spout 40 connecting the upper and lower portions of the bag body 3 By folding the folding container so that the folding directions are symmetrical in the same direction, the liquid container 1 can be more easily expanded in the outer container 5 when inserted into the outer container 5.

  The folding in the vertical direction is not limited to the case of folding at the center line, and may be a bellows-like folding as long as the liquid storage container 1 can be inserted into the outer container 5 from the opening 5a of the outer container 5.

  Next, as shown in FIG. 12, the liquid storage container 1 folded in a bellows shape along the vertical folding line 15 has a plurality of, for example, two, provided vertically to maintain this folded shape. It is fixed by the shape-retaining parts 17 and 18, and the shape is maintained.

  Each of the shape retaining portions 17 and 18 maintains the folded shape of the liquid storage container 1, and gas is supplied from the spout 40 into the liquid storage container 1 as will be described later. When inflating, the shape retaining portions 17 and 18 are broken and detached from the liquid storage container 1. In this case, when gas is supplied from the spout 40 into the liquid storage container 1, the upper portion of the liquid storage container 1 first swells and the upper shape retaining portion 17 breaks and comes off from the liquid storage container 1. The lower part of the liquid container 1 is sent to the lower part of the liquid container 1 to swell, and the lower shape-retaining part 18 is broken and detached from the liquid container 1. Such shape-retaining portions 17 and 18 may be tape-shaped, but may be formed of a rubber-like band-shaped tape or an adhesive. Also, the tape can be removable and can be broken. Further, the number of the shape retaining portions 17 and 18 may be one, or may be two or more.

  Next, the spout 40 of the liquid storage container 1 will be described in detail. As shown in FIG. 13, the spout 40 includes a spout attachment portion 50 that is heat-sealed to the upper edge 3 a of the bag body 3, and a note that is connected to the spout attachment portion 50 and protrudes outward from the bag body 3. A spout flange 42 is provided at the upper end of the spout main body 41. Further, as shown in FIG. 13, the spout 40 is heat-sealed between the first base material portion 2 </ b> A and the second base material portion 2 </ b> B at the spout mounting portion 50.

  Further, the spout main body 41 of the spout 40 is formed of a cylindrical body having a substantially U-shaped cross section, and a spout flange 42 is provided at the upper peripheral edge. An opening 44 is formed in the bottom 43 of the spout main body 41. The opening 44 can ensure ventilation between the liquid storage container 1 and an outer container 5 to be described later. When the content liquid is pumped out during use, the liquid storage container 1 and the outer container 5 are opened through the opening 44. The gas can be sealed between the two and a pressure can be applied from the outside of the liquid storage container 1 to smoothly pump out the content liquid inside the liquid storage container 1.

  A spout flange 42 of the spout 40 is attached to an opening 5 a formed in the outer container 5 via a holder 80 described later, and the liquid storage container 1 is supported in the outer container 5. If the spout 40 can be directly attached to the opening 5a, the holder 80 is not necessarily provided.

  Next, the material of each component will be described. The spout 40 is preferably manufactured by an injection molding method. The resin used for this is not particularly limited as long as it is a resin that can be injection-molded. However, the resin that forms the inner surfaces of the first base material portion 2A and the second base material portion 2B of the bag body 3 is thermally fused. In order to be joined by adhesion, it is necessary to select appropriately depending on the resin constituting the inner surface of the first base material portion 2A and the second base material portion 2B, but usually it is rigid even at high temperatures, and at low temperatures High density polyethylene that is not easily embrittled is suitable.

  As the material of the bag body 3, a laminate of unstretched nylon (thickness 20 μm) 20a / linear low density polyethylene (thickness 40 μm) 20b and linear low density polyethylene (thickness 70 μm) were further laminated. Things can be used.

  In addition, as a material of the bag main body 3, it is not restricted to what was mentioned above.

  For example, as the material of the bag body 3, materials such as low density polyethylene, low density polyethylene and linear low density polyethylene can be used.

  By the way, as described above, the spout flange 42 of the spout 40 is attached to the opening 5 a of the outer container 5 via the holder 80. The holder 80 is interposed between the opening 5 a and the spout 40, and even if the shape of the opening 5 a of the outer container 5 is slightly larger than the outer shape of the spout flange 42, the spout 40 is provided in the opening 5 a. It functions to be surely installed.

The holder 80 will be described in detail with reference to FIGS. 15A to 18.
The holding tool 80 includes an outer flange 81 that engages with the opening 5 a of the outer container 5, and an inner flange 82 that is connected to the outer flange 81 via a connecting step 83 and engages with the spout flange 42 of the spout 40. And has a ring shape having an opening 80a as a whole.

  The inner flange 82 of the holder 80 has an opening 80a having a substantially ring shape. The inner flange 82 is provided with a pair of notches 85 and 85 facing each other on a straight line passing through the center thereof (see FIGS. 15A and 15B).

  The spout 40 of the liquid storage container 1 is attached to the holder 80 configured as described above through the pair of notches 85 (see FIG. 16). In this case, the spout flange of the spout 40 is provided. 42 has a ring shape (circular shape). The spout flange 42 that has passed between the pair of notches 85 of the holder 80 is locked to the inner flange 82 of the holder 80 (see FIGS. 16 to 18).

  In addition, it is not necessary to limit to the thing of the above structures as the holder 80, You may use what has a two-part structure via the dividing line.

Next, the operation of the present embodiment having such a configuration will be described.
First, the liquid storage container 1 configured as described above, that is, having a rectangular bottom surface 30 and a rectangular top surface 35, the upper edge joint portion 10a and the bottom edge joint portion 10b are overlapped, and these upper edge joints are overlapped. The liquid storage container 1 is prepared in which the portion 10a and the bottom edge joint portion 10b are folded in two along the crease line, folded along the longitudinal folding line 15 and fixed by the shape retaining portions 17 and 18 (see FIG. 12). ).

  Next, as shown in FIG. 19, the liquid storage container 1 is inserted into the exterior container 5 from the opening 5 a of the exterior container 5. In this case, the exterior container 5 is a large container made of metal or synthetic resin, has a rectangular parallelepiped box shape, and has a large capacity of, for example, about 1000 l.

  Next, the holding tool 80 is attached to the spout 40 with the spout 40 of the liquid storage container 1 protruding from the outside of the opening 5a. In this case, as described above, the spout 40 is first inclined with respect to the holder 80 as shown in FIG. In FIG. 16, the spout 40 is inclined by 90 ° with respect to the holder 80.

  Next, the spout flange 42 of the spout 40 passes through the space extending between the pair of notches 85 of the holder 80.

  In this case, since the length between the pair of notches 85 is larger than the outer diameter of the ring-shaped spout flange 42, the spout flange 42 smoothly passes through the space extending between the pair of notches 85. Can be made. At this time, the spout 40 also passes through the opening 80a of the holder 80 as a whole.

  After the spout 40 passes through the opening 80 a of the holder 80 as a whole, the spout 40 is rotated with respect to the holder 80, and the spout 40 is brought parallel to the holder 80.

  In this case, the minimum inner diameter a1 corresponding to the inner diameter of the ring shape of the inner flange 82 is smaller than the maximum outer diameter b1 of the outlet flange 42 corresponding to the outer diameter of the ring shape. The inner flange 82 of the 80 can be securely locked.

  In this way, a spout / holder combination 80A having the spout 40 and the holder 80 can be obtained (see FIGS. 17 and 18).

  In the above embodiment, the example in which the holder 80 is attached to the spout 40 after the liquid storage container 1 is inserted into the outer container 5 is shown. After mounting, the liquid storage container 1 may be inserted into the outer container 5. Further, the holder 80 is not necessarily used.

  Next, a spout and holder combination 80 </ b> A having the spout 40 and the holder 80 is attached to the opening 5 a of the outer container 5. In this case, the outer flange 81 of the holder 80 engages with the opening 5a of the outer container 5 (see FIGS. 20 and 21).

  By the way, as the exterior container 5 shown in FIG. 19, a rectangular parallelepiped large-sized synthetic resin container can be used, but as the exterior container 5, a metal canister can, a synthetic resin drum can, and a metal container can be used. Thus, not only a rectangular parallelepiped shape but also a cubic shape may be used.

  Next, an expansion jig (not shown) is attached to the spout 40 of the liquid storage container 1, and nitrogen gas or clean dry air is supplied into the liquid storage container 1 using the expansion jig, and the outer container 5. Inside, the bag body 3 of the liquid container 1 swells.

Next, the effect | action which expands the liquid storage container 1 in the exterior container 5 is demonstrated below.
As described above, the bag body 3 is inflated by supplying nitrogen gas or clean dry air into the liquid storage container 1 using an inflating jig. In this case, first, a gas such as nitrogen gas or clean dry air is supplied from the spout 40 into the liquid storage container 1. At this time, the upper portion of the liquid container 1 is first swollen by the gas, and the upper shape retaining portion 17 is broken and detached from the liquid container 1. Next, the gas is sent from the upper part of the liquid container 1 to the lower part, and the lower shape retaining part 18 is broken. In this way, the bag body 3 of the liquid storage container 1 folded along the longitudinal folding line is gradually expanded.

  Next, the bottom surface 30 of the bag body 3 falls while maintaining a rectangular shape, and comes into contact with the bottom of the outer container 5. Thereafter, the bag body 3 swells between the upper surface 35 and the bottom surface 30 while maintaining the shape of the rectangular bottom surface 30 and the rectangular upper surface 35.

  In this case, the bag body 3 is expanded between the rectangular upper surface 35 and the rectangular bottom surface 30 so that the bag body 3 itself expands in a rectangular parallelepiped shape along the inner surface of the rectangular parallelepiped box-shaped outer container 5. The outer shape of the liquid storage container 1 is arranged in the mold outer container 5 so as to be along the inner surface of the box-type outer container 5.

By the way, in the present embodiment, the liquid storage container 1 is folded in a bellows shape and fixed by a pair of shape retaining portions 17 and 18 provided above and below. When not provided, it is also conceivable that the gas supplied into the liquid storage container 1 is immediately sent to the lower part and the upper part is less likely to expand, so that the liquid storage container 1 expands unevenly. When the liquid storage container 1 swells unevenly, the bag body 3 cannot be filled with a desired amount of liquid. According to the present embodiment, after the liquid storage container 1 is folded in a bellows shape, the upper and lower sides thereof are fixed by the pair of shape retaining portions 17 and 18, thereby supplying the gas supplied into the liquid storage container 1. Are sequentially sent from the upper part to the lower part, so that the bag body 3 of the liquid container 1 can be gradually and uniformly inflated in order from the upper part to the lower part. As a result, the bag body 3 can be filled with a desired amount of liquid.
However, the pair of shape retaining portions 17 and 18 are not necessarily provided.

  As described above, according to the present embodiment, the liquid storage container 1 inserted from the opening 5 a into the rectangular parallelepiped box-shaped outer container 5 can be easily and reliably inflated in accordance with the inner surface shape of the outer container 5. it can. For this reason, the liquid container 1 can be filled with the liquid by effectively using the liquid container 1 swelled in conformity with the inner surface shape of the outer container 5.

  In this way, a combined body of the outer container 5 and the liquid storage container 1 is obtained. Thereafter, the inflating jig is removed from the spout 40, and a content liquid filling machine (not shown) is attached to the spout 40, and the content liquid is filled into the liquid storage container 1 from the content liquid filling machine.

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

  Next, the holder 80 is removed from the spout 40. In this case, the holder 80 is removed from the spout 40 by a procedure reverse to the above-described procedure of attaching 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 holding tool 80 is removed from the spout 40, the spout 40 opens to the opening 5 a. And then falls into the outer container 5.

  Next, an 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 having the opening cap 5A attached to the opening 5a is transported to the transport destination.

  Next, when the exterior container 5 is transported to the transport destination, the opening cap 5 </ b> A is removed from the opening 5 a of the exterior container 5.

  Thereafter, the spout cap is removed from the spout 40 attached to the opening 5 a of the outer container 5.

  Next, the spout upper member 70 in which the liquid distribution nozzle 60 is screwed and held in advance is mounted in the spout main body 41 of the spout 40 mounted in the opening 5a of the outer container 5 (FIGS. 20 and 21). reference).

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

  Next, the content liquid in the liquid container 1 is discharged to the outside. In this case, the liquid distribution nozzle 60 is connected to the dispenser via the connection pipe 63.

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

  In the above embodiment, after the liquid storage container 1 is inserted into the outer container 5, the liquid storage container 1 is placed in the outer container 5 by supplying nitrogen gas or clean dry gas into the liquid storage container 1. Although the example which expands was shown, after inserting the liquid storage container 1 in the exterior container 5 without being limited to this, the liquid storage container 1 is immediately filled with the content liquid from the content liquid filling machine, thereby the liquid storage container 1. The liquid container 1 may be filled with the content liquid while inflating the liquid.

  In this case, when the content liquid is filled into the liquid storage container 1 in the outer container 5, the content liquid is first sent to the lower part of the liquid storage container 1 by its own weight to form the rectangular bottom surface 30 of the bag body 3. It swells from the lower part. If the lower shape-retaining part 18 is provided in accordance with the swelling of the lower part, it is broken. Thus, the bag main body 3 of the liquid storage container 1 folded along the vertical folding line is gradually expanded from the lower portion to the upper portion, so that the rectangular upper surface 35 of the bag main body 3 is also formed. .

  When the bag body 3 is filled with a predetermined amount of the content liquid, the bottom surface 30 of the bag body 3 falls while maintaining the rectangular shape and comes into contact with the bottom of the outer container 5. Thereafter, the bag body 3 swells between the upper surface 35 and the bottom surface 30 while maintaining the shape of the rectangular bottom surface 30 and the rectangular upper surface 35.

  In this case, the bag body 3 is expanded between the rectangular upper surface 35 and the rectangular bottom surface 30 so that the bag body 3 itself expands in a rectangular parallelepiped shape along the inner surface of the rectangular parallelepiped box-shaped outer container 5. The outer shape of the liquid storage container 1 is arranged in the mold outer container 5 so as to be along the inner surface of the box-type outer container 5.

  As described above, according to the present embodiment, the liquid storage container 1 inserted from the opening 5 a into the rectangular parallelepiped box-shaped outer container 5 can be easily and reliably inflated in accordance with the inner surface shape of the outer container 5. The liquid container 1 can be filled with the content liquid by effectively using the liquid container 1 swelled in accordance with the inner surface shape of the outer container 1. In this case, in particular, the content liquid is placed in the liquid storage container 1 while the bag body 3 forms the rectangular bottom surface 30 and the rectangular top surface 35 so that the liquid storage container 1 is inflated.
