<First Embodiment of the Present Invention>

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

1 to 18 are views showing an embodiment of the present invention.

First, the liquid storage container 1 will be described.

The liquid storage container 1 is provided with a plurality of thin films 2 in which the outer bag 20 and the inner bag 21 are stacked, and the inner bag 21 is superposed on each other so as to face each other, and four of them are heat-sealed and sealed to form a heat-pressure sealing portion. The bag body 3 of 10; and the injection port 40 disposed between the inner bag 21 and the upper edge 3a of the bag body 3 are thermally fused in advance.

In the present embodiment, the bag body 3 is stacked such that the inner bags 21 of the multiple film 2 face each other, and the hot press seal portion 10 is formed by heat sealing the four sides, but is not limited thereto, and for example, After the multiple film 2 inner bag 21 is bent in such a manner as to face each other, the three sides of the laminated outer periphery may be formed by thermocompression sealing. Further, each of the inner edges of the heat-pressure sealing portion 10 may be formed such that its inner edge is formed in an arc shape. By this, become The fluid content is less likely to remain in the structure of the corners. Further, the bag body does not necessarily have to be composed of a plurality of films, and the film constitution of the bag body 3 can be appropriately selected in accordance with the contents and the capacity.

Further, in the present embodiment, the bag main body 3 is formed by stacking two multi-films. However, the present invention is not limited thereto, and two sheets of the film are prepared by heat-sealing the four sides, or One film is folded back and the three sides are sealed by heat sealing, and the bag body 3 may be formed of a single layer film.

Further, in the bag body 3, the two multi-films 2 are stacked, and the hot-pressure seal portion 10 is formed by heat-sealing the periphery. In this case, the bag body 3 has a rectangular shape including the upper edge 3a, the bottom edge 3b, and the 2 side edges 3c, 3c. The upper edge 3a is an upper edge hot press seal portion 10a including two strips, and the bottom edge 3b is a bottom edge hot press seal portion 10b including one strip, and each side edge 3c, 3c is a side edge hot press seal portion having one strip. 10c, the upper edge heat seal portion 10a, the bottom edge heat seal portion 10b, and the side edge heat seal portion 10c constitute the heat seal portion 10.

In the present embodiment, the upper edge 3a of the bag body 3 may include the upper edge hot-press seal portion 10a as described above, but a hot-pressure seal portion may be formed in the upper edge 3a. In the present embodiment, the heat-pressure sealing portion 10a of the upper edge 3a is divided into two, for example, one hot-pressed sealing portion having a width of the hot-pressed sealing portion 10a having two points is formed on the upper edge 3a. In contrast, the upper edge 3a can be constructed to be relatively soft.

The injection port 40 has a spout attachment portion 50 that is thermally fused to the upper edge 3a of the bag body 3, and a spout body 41 that is connected to the spout attachment portion 50 and protrudes outward from the bag body 3. In the note The upper end of the mouth body 41 is provided with a spout flange 42. Further, as shown in Fig. 1, the injection port 40 is thermally welded to the inner bag 21 of the multiple film 2 at the injection port mounting portion 50.

The injection port attachment portion 50 of the injection port 40 has a central portion 51 and a thin portion 52 which is provided on both sides of the central portion 51 and which is thinner than the thickness of the central portion 51 as shown in Figs. 2 to 7 . The elliptical cylinder is formed in a flat shape and has a through hole 45 in the center portion 51. Normally, when the injection port 40 is thermally fused between the inner bag 21 of the multiple film 2 in the injection port mounting portion 50, the inner bag 21 and the two portions surrounded by the end portion of the injection port mounting portion 50 are formed. It is easy to be a poor seal due to the gap. In order to prevent this, the thin portion 52 is provided on both sides, and the gap can be prevented by melting the thin portion 52 at the time of heat fusion.

The injection port body 41 of the discharge port 40 is formed of a cylindrical body having a U-shaped cross-sectional shape, and a discharge port flange 42 is provided on the periphery of the upper end. In the bottom portion 43 of the spout body 41, an opening 44 is formed. By the opening 44, it is possible to ensure ventilation between the liquid storage container 1 and the outer container 5 to be described later, and when the content liquid is taken out during use, the liquid storage container 1 and the outer container 5 are connected via the opening 44. The gas is sealed, and pressure is applied from the outside of the liquid storage container 1 so that the extraction of the content liquid inside the liquid storage container 1 can be smoothly performed. Further, in the bottom portion 43 in the discharge port body 41, the discharge port upper member 70 is provided to extend in the vertical direction.

The injection port flange 42 of the injection port 40 is attached to the opening 5a formed in the outer casing 5 through a holder 80 to be described later, and the liquid is collected. The nano container 1 is supported in the outer container 5.

The injection port 40 is preferably manufactured by an injection molding method. The resin to be used for the injection molding is not particularly limited. However, since the resin constituting the inner surface of the inner bag 21 constituting the multiple film 2 is joined by heat fusion, it is necessary to form the inner bag 21 according to the composition. The resin on the inner surface is suitably selected, but it is usually rigid at a high temperature, and high-density polyethylene which is difficult to embrittle at a low temperature is most preferable.

As shown in Fig. 9, the outer bag 20 of the bag body 3 can be a laminate of unstretched nylon (thickness 20 μm) 20a/linear low-density polyethylene (thickness 40 μm) 20b, and the inner bag 21 can be linear. Low density polyethylene (thickness 70 μm).

In this case, since the outer bag 20 contains the unstretched nylon 20a, the elongation of the outer bag 20 can be increased, for example, the outer bag 20 has an elongation of 300% to 500%. For example, since the bag 20 can have a high elongation, the bag body 3 can be entirely softened, and the bag body 3 can be inserted into the outer container 5 as will be described later, and the bag body 3 is supplied with a nitrogen gas body and a clean dry air bag. When the body 3 is inflated in the outer container, the bag body 3 can be smoothly expanded.

Further, the material of the bag body 3 is not limited to the above.

For example, the material of the inner bag 21 is a material such as low density polyethylene, low density polyethylene, and linear low density polyethylene.

Further, the material of the outer bag 20 is such that the elongation is 300% to 500%, and materials such as low density polyethylene and linear low density polyethylene can be used.

However, as described above, the discharge port flange 42 of the discharge port 40 is provided in the opening portion 5a of the outer casing 5 through the holder 80. The holder 80 is positioned between the opening 5a and the injection port 40, and the shape of the opening 5a of the outer casing 5 can be surely mounted even if the outer shape of the outlet flange 42 is larger. It is provided in the opening 5a to function.

Next, the holder 80 will be described in detail with reference to FIGS. 10A through 18.

The holder 80 has an outer flange 81 that is engaged with the opening 5a of the outer casing 5, and an injection port flange 42 that is coupled to the outer flange 81 through the connection step portion 83 and that is engaged with the injection port flange 42 of the injection port 40. The inner flange 82 is formed by a ring shape having an integral opening 80a.

Further, the inner flange 82 of the holder 80 has a ring shape having an opening 80a formed therein, and its inner diameter is a1. Further, in the inner flange 82, a pair of notches 85, 85 facing each other are provided on a straight line passing through the center thereof, and the inner diameter of the inner flange 82 passing through the notches 85, 85 is a2 (Fig. 10) A and Figure 10B refer to).

Therefore, as shown in Fig. 10A, the minimum inner diameter of the inner flange 82 is a1, and the maximum inner diameter is a2.

The holder 80 thus configured is attached to the discharge port 40 of the liquid storage container 1 (refer to FIGS. 11 to 13). In this case, the injection port flange 42 of the injection port 40 is formed in a ring shape (circular shape). Therefore, the maximum outer diameter b1 and the minimum outer diameter b2 of the discharge port flange 42 are equal to each other (refer to FIG. 4).

However, the injection port flange 42 is formed into an elliptical shape, and the outlet is The flange 42 may have a maximum outer diameter b1 and a minimum outer diameter b2 smaller than the maximum outer diameter (refer to the 2-point lock line in Fig. 4).

Next, the relationship between the minimum inner diameter a1 and the maximum inner diameter a2 of the inner flange 82 of the holder 80 and the maximum outer diameter b1 and the minimum outer diameter b2 of the injection port flange 42 of the injection port 40 will be described.

As shown in Fig. 18, the maximum inner diameter a2 of the inner flange 82 is larger than the minimum outer diameter b2 of the injection port flange 42, and becomes a2 > b2.

The minimum inner diameter a1 of the inner flange 82 is smaller than the maximum outer diameter b1 of the injection port flange 42 and becomes a1 < b1.

Thus, since a2>b2 is formed, the discharge port flange 42 is a space which can extend between the pair of notches 85 of the holder 80. Further, since a1 < b1 is passed, the injection port flange 42 between the pair of notches 85 of the holder 80 is locked to the inner flange 82 of the holder 80.

However, the minimum inner diameter a1 and the maximum inner diameter a2 of the inner flange 82 of the holder 80 and the maximum outer diameter b1 and the minimum inner diameter b2 of the injection port flange 42 of the injection port 40 may be limited as follows.

That is, the minimum inner diameter a1 of the inner flange 82 of the holder 80 is the minimum length of a straight line connecting the two points facing the inner edge 82A of the inner flange 82, and the inner flange 82 of the holder 80 The maximum inner diameter a2 is the maximum length of a straight line connecting the two points facing the inner edge 82A of the inner flange 82.

The maximum outer diameter b1 of the injection port flange 42 of the injection port 40 is 2 points which face each other of the outer edge 42A of the discharge port flange 42. The maximum length of the straight line that is connected to each other, and the minimum outer diameter b2 of the injection port flange 42 of the injection port 40 is the minimum length of a straight line connecting the two points facing the outer edge 42A of the injection port flange 42 to each other.

Here, the "between two points facing each other" of the above a2 and b2 is defined so that the injection port flange 42 smoothly passes through the space in the holder 80 between the two points facing each other.

The "between two points facing each other" of the above a1 and b1 is defined so that the injection port flange 42 can be engaged with the inner flange 82 of the holder 80 between the two points facing each other.

Next, the action of this embodiment constituted by such a configuration will be described.

First, the liquid storage container 1 configured as described above is prepared.

Next, as shown in Fig. 8, the liquid storage container 1 is folded in the longitudinal direction to form a longitudinally elongated shape, and the liquid storage container 1 is inserted into the outer casing 5 from the opening 5a.

Next, in a state where the injection port 40 of the liquid storage container 1 protrudes outward from the opening 5a, the holder 80 is attached to the injection port 40. In this case, first, as shown in Fig. 18, the spout 40 is inclined with respect to the holder 80. In Fig. 18, the spout 40 is disposed such that the holder 80 is inclined by 90°.

The injection port flange 42 of the injection port 40 is then passed through a space extending between the pair of notches 85 of the holder 80.

In this case, the maximum inner diameter a2 of the inner flange 82 of the pair of notches 85 is larger than the outer diameter of the corresponding ring shape. Since the minimum outer diameter b2 of the rim 42 is large, the spout flange 42 can be smoothly passed through the space extending between the pair of notches 85. At this time, the injection port 40 is also entirely passed through the opening 80a of the holder 80.

After the injection port 40 passes through the opening 80a of the holder 80 as a whole, the injection port 40 is rotated about the holder 80, and the injection port 40 is made 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 discharge port flange 42 corresponding to the outer diameter of the corresponding ring shape, so that the discharge port flange 42 can be used. The inner flange 82 of the holder 80 is securely locked.

Thus, the combination 80A (refer to Figs. 11 to 17) having the injection port 40 and the holder 80 of the holder 80 can be obtained.

Further, in the above-described embodiment, after the liquid storage container 1 is inserted into the outer casing 5, an example in which the holder 80 is attached to the injection port 40 is shown. However, the present invention is not limited thereto, and the holder 80 is attached to the injection port 40. Thereafter, the liquid storage container 1 may be inserted into the outer container 5.

Next, the assembly 80A having the injection port 40 and the holder of the holder 80 and the holder 80 is attached to the opening 5a of the exterior container 5. In this case, the outer flange 81 of the holder 80 is engaged with the opening 5a of the outer casing 5 (see FIGS. 6 and 7).

However, the outer container 5 shown in Fig. 8 may be a large-sized synthetic resin container having a rectangular tube shape (capacity: 1000 kg), but the outer container 5 may be a cylindrical container.

Alternatively, the outer container 5 may be a metal tube, a synthetic resin barrel, or a metal container.

Next, an inflation jig (not shown) is attached to the injection port 40 of the liquid storage container 1, and a nitrogen gas or clean dry air is supplied into the liquid storage container 1 by using the inflation jig, and the inside of the outer container 5 is made. The bag body 3 of the liquid storage container 1 is inflated.

Next, as described above, the bag body 3 is inflated by supplying the nitrogen gas or the clean dry air using the inflation jig in the liquid storage container 1. Along with this, the bag body 3 folded in the longitudinal direction is expanded flat.

Further, since the upper edge 3a of the bag body 3 includes the two upper edge heat-pressure seal portions 10a, the upper edge 3a can be softly configured as compared with the case of including the wide-pressure heat-pressure seal portion, and the bag body 3 can be formed. It expands more smoothly in the outer container 5. Further, since the outer bag 20 of the bag body 3 has an elongation of 300% to 500%, the flexibility of the bag body 3 can be improved, and the expansion of the bag body 3 can be easily performed.

In this way, a combination of the outer container and the liquid container can be obtained. Thereafter, the inflation jig is removed from the injection port 40, and the content liquid filling machine (not shown) is installed in the injection port 40, and the content liquid is filled into the liquid storage container 1 from the content liquid filling machine.

After the content liquid is filled in the liquid storage container 1, as shown in Figs. 6 and 7, the injection port body 41 of the injection port 40 installed in the opening 5a of the outer casing 5 is provided in advance. Dispensing liquid The nozzle 60 is screwed to hold the outlet upper member 70. In this case, the spout upper member 70 has the external thread 70a, and the spout body 41 has the internal thread 41a. The external thread 70a is engaged with the internal thread 41a, so that the spout upper member 70 is fixed to the spout body 41. Inside. The liquid dispensing nozzle 60 is screwed to the spout upper member 70 by engaging the external thread 60a of the liquid dispensing nozzle 60 with the internal thread 70b of the spout upper member 70.

Further, the liquid dispensing nozzle 60 has a dome-shaped portion 61 formed at a lower end thereof, and a plurality of openings 62 are formed in the dome-shaped portion 61. The dome-shaped portion 61 is formed in a hemispherical shape, and a plurality of openings 62 are formed in the hemispherical surface. The dome-shaped portion 61 may have a hemispherical shape at the lower end of the liquid dispensing nozzle 60 or a hemispherical nozzle cap may be attached to the lower end of the liquid dispensing nozzle 60.

After the filling step of the content liquid in the liquid storage container 1 is completed, the opening portion 5A is attached to the opening 5a of the outer container 5 (refer to FIG. 8). In this manner, the injection port 40 and the liquid dispensing nozzle 60 are sealed.

When the content liquid in the liquid storage container 1 is discharged to the outside, the opening cap 5A is removed, and the liquid dispensing nozzle 60 is connected to the dispenser through the connection rigid tube 63.

Next, the nitrogen gas is supplied from the pressurized gas source (not shown) to the injection port body 41 of the injection port 40, and thereafter the nitrogen gas is opened. The mouth 44 enters the space between the outer casing 5 and the bag body 3 of the liquid storage container 1. Then, the bag body 3 is pressed by the nitrogen gas from the outside, and the content liquid in the bag body 3 enters the liquid dispensing nozzle 60 from the opening 62 of the dome-shaped portion 61, so that the content liquid in the liquid dispensing nozzle 60 is removed from the liquid. Thereafter, the connecting rigid tube 63 is discharged toward the dispenser side. Alternatively, a suction pump (not shown) may be connected to the injection port 40, and the discharge generated by the suction pump may be performed. At this time, the bag body 3 is shrunk as it is discharged, and since the outer side of the bag body 3 is maintained at atmospheric pressure, the outer container 5 is not deformed or the like even if it is not a pressure-resistant container.

Here, since the liquid dispensing nozzle 60 has the dome-shaped portion 61 at the lower end thereof, the liquid in the bag body 3 is discharged from the connecting tube 63 to the outside through the liquid dispensing nozzle 60, and the liquid dispensing nozzle 60 is disposed. Even if the lower end abuts against the inner surface of the bag body 3, the bag body 3 can be prevented from being broken by the lower end of the liquid dispensing nozzle 60.

Further, the content liquid in the bag body 3 is sucked into the liquid dispensing nozzle 60 through the plurality of openings 62 provided in the dome-shaped portion 61, and is discharged from the connecting tube 63 toward the dispenser side. Therefore, even if the residual amount of the content liquid is reduced as compared with the case where a single opening is provided in the center of the lower end of the liquid dispensing nozzle 60, the bag body 3 can be in close contact with the liquid dispensing nozzle 60 to prevent the content liquid from being easily distributed toward the liquid dispensing nozzle 60. Flow inside.

As described above, according to the present embodiment, since the holder 80 is constituted by a ring shape having the outer flange 81 and the inner flange 82, for example, the holder 80 is formed in a U shape or has a hinge portion as a center.

<Second embodiment>

Next, a second embodiment will be described with reference to Figs. 22 to 26 .

The second embodiment shown in FIGS. 22A to 26 is different from the method of using the combination of the outer container and the liquid container, and the other configuration is the first embodiment shown in FIGS. 1 to 21C. The examples are roughly the same.

In the second embodiment shown in Figs. 22A to 26, the same portions as those in the first embodiment shown in Figs. 1 to 21C are denoted by the same reference numerals, and detailed description thereof will be omitted.

First, as shown in Fig. 22A, the liquid storage container 1 is inserted into the outer container 5.

At this time, as shown in Fig. 8, the liquid storage container 1 is folded in the longitudinal direction to form a longitudinally elongated shape, and the liquid storage container 1 is inserted into the outer casing 5 from the opening 5a.

Next, in a state where the injection port 40 of the liquid storage container 1 protrudes outward from the opening 5a, the holder 80 is attached to the injection port 40. In this case, first, as shown in Fig. 18, the spout 40 is inclined with respect to the holder 80. In Fig. 18, the spout 40 is disposed such that the holder 80 is inclined by 90°.

The injection port flange 42 of the injection port 40 is then passed through a space extending between the pair of notches 85 of the holder 80.

In this case, since the maximum inner diameter a2 of the inner flange 82 of the pair of notches 85 is larger than the minimum outer diameter b2 of the spout flange 42 corresponding to the outer diameter of the ring shape, the spout flange 42 can be used. Smoothly passes through the space extending between the pair of notches 85. At this point, the outlet 40 is also It passes through the opening 80a of the holder 80 as a whole.

After the injection port 40 passes through the opening 80a of the holder 80 as a whole, the injection port 40 is rotated about the holder 80, and the injection port 40 is made 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 discharge port flange 42 corresponding to the outer diameter of the corresponding ring shape, so that the discharge port flange 42 can be used. The inner flange 82 of the holder 80 is securely locked.

Thus, the combination 80A (refer to Figs. 11 to 17) having the injection port 40 and the holder 80 of the holder 80 can be obtained.

Further, in the above-described embodiment, after the liquid storage container 1 is inserted into the outer casing 5, an example in which the holder 80 is attached to the injection port 40 is shown. However, the present invention is not limited thereto, and the holder 80 is attached to the injection port 40. Thereafter, the liquid storage container 1 may be inserted into the outer container 5.

Next, the assembly 80A having the injection port 40 and the holder of the holder 80 and the holder 80 is attached to the opening 5a of the exterior container 5. In this case, the outer flange 81 of the holder 80 is engaged with the opening 5a of the outer casing 5 (see FIGS. 6 and 7).

However, the outer container 5 shown in Fig. 8 may be a large-sized synthetic resin container having a rectangular tube shape (capacity: 1000 kg), but the outer container 5 may be a cylindrical container.

Alternatively, the outer container 5 may be a metal tube, a synthetic resin barrel, or a metal container.

Next, as shown in FIG. 22B, an inflation jig 90 is attached to the injection port 40 of the liquid storage container 1, and the inflation device 90 is used to supply a nitrogen gas or a clean dry air to the liquid storage container 1, and the outer casing is externally mounted. The bag body 3 of the liquid storage container 1 is inflated in the container 5.

Next, the action of expanding the liquid storage container 1 in the outer casing 5 will be described below.

Next, as described above, the bag body 3 is inflated by supplying the nitrogen gas or the clean dry air using the inflation jig in the liquid storage container 1. Along with this, the bag body 3 folded in the longitudinal direction is expanded flat.

Further, since the upper edge 3a of the bag body 3 includes the two upper edge heat-pressure seal portions 10a, the upper edge 3a can be softly configured as compared with the case of including the wide-pressure heat-pressure seal portion, and the bag body 3 can be formed. It expands more smoothly in the outer container 5. Further, since the outer bag 20 of the bag body 3 has an elongation of 300% to 500%, the flexibility of the bag body 3 can be improved, and the expansion of the bag body 3 can be easily performed.

In this way, a combination of the outer container and the liquid container can be obtained. Thereafter, the inflation jig 90 is removed from the injection port 40, and the content liquid filling machine 91 is installed in the injection port 40, and the content liquid is filled in the liquid storage container 1 from the content liquid filling machine (Fig. 22) C reference).

Thus, as shown in Fig. 22D, after the inner solution is filled into the liquid storage container 1, the injection port cap 40A is attached to the injection port 40. The injection port cap 40A has an external thread that engages with the internal thread 41a of the spout body 41 in the spout 40, and the spout cap 40A is engaged with the internal thread 41a of the spout body 41 by the external spline 40A. Installed at the exit 40 (refer to Figure 6 and Figure 7).

Next, as shown in Fig. 22E, the holder 80 is removed from the spout 40. In this case, the holder 80 is removed from the injection port 40 by the reverse of the above-described steps of being installed in the injection port 40.

Since the inner diameter of the opening 5a of the outer casing 5 is larger than the outer diameter of the injection port flange 42 of the injection port 40, when the holder 80 is removed from the injection port 40, the injection port 40 passes through the opening 5a. It falls into the outer container 5.

In the present embodiment, the injection port 40 is housed in the outer casing 5 via the opening 5a, and the injection port 40 is placed on the upper surface of the bag body 3 of the liquid storage container 1. At this time, the tape 95 is provided in advance through the opening 44 of the spout 40 as described later, and the upper end of the tape 95 is attached to the ceiling of the outer casing 1 through the adhesive portion 95a.

As described above, the holder 80 is removed from the discharge port 40 of the liquid storage container 1 housed in the outer casing 5, and the holder 80 is stored in the filling place of the content liquid.

Further, the holder 80 attached to the discharge port 40 does not need to have the structure shown in Figs. 10A and 10B. As shown in Figs. 23A and 23B, the holder 80 is split. The line L may have a two-division structure. The holder 80 of the two-divided structure shown in FIGS. 23A and 23B has an outer flange 81 and an inner flange 82, and a vent 82a is formed in the inner flange 82. Moreover, the holder 80 is as A multi-segment structure of a three-division structure or a four-division structure may be used.

This vent 82a is a ventilator that secures between the liquid storage container 1 and the outer container 5. In the inflation of the liquid storage container 1, the nitrogen gas or the clean dry air is supplied into the liquid storage container 1, and when the bag body 3 is inflated, the air in the outer container 5 is exhausted toward the outside of the outer container 5. This exhaust gas can be smoothly performed. When the content liquid is discharged from the liquid storage container 1, the gas is sealed between the liquid storage container 1 and the outer container 5 through the vent 82a, and the content liquid inside the liquid storage container 1 can be applied by applying pressure from the outside of the liquid storage container 1. Smoothly discharged. Alternatively, a suction pump (not shown) may be connected to the injection port 40, and the discharge generated by the suction pump may be performed. At this time, the bag body 3 is shrunk as it is discharged, and since the outer side of the bag body 3 is maintained at atmospheric pressure, the outer container 5 is not deformed even if it is not a pressure-resistant container.

Next, the outer casing 5 in which the opening cap 5A is attached to the opening 5a is conveyed until the conveyance destination.

When the outer casing 5 is transported to the destination, the opening cap 5A is removed from the opening 5a of the outer casing 5.

Next, as shown in Fig. 24, in the conveyance destination, the injection port 40 placed on the upper surface of the bag body 3 is pulled up. When the content liquid is filled, the tape 95 is previously provided through the opening 44 of the injection port 40, and the upper end of the tape 95 is attached to the ceiling of the outer container 5 through the adhesive portion 95a, so the operator holds the tape 95. The injection port 40 is pulled up, and the injection port 40 is pulled out from the exterior container 5 through the opening 5a.

The tape 95 which is attached to the ceiling of the outer casing 5 at the upper end functions as a pull-out tool of the spout 40.

Next, the holder (additional holder) 80 is attached to the injection port 40 which is pulled outward from the opening 5a in the same manner as described above. The assembly 80A having the injection port 40 and the holder of the holder 80 and the holder 80 thereafter is installed in the opening 5a of the exterior container 5. In this case, the outer flange 81 of the holder 80 is engaged with the opening 5a of the outer casing 5 (see FIGS. 6 and 7).

In addition, although the holder 80 is stored in the holder to be transported, the holder 80 used in the filling place may be directly transported and used.

Thereafter, the spout cap 40A is removed from the spout 40 that is installed in the opening 5a of the outer casing 5.

Next, the injection port upper member 70 that screws the pre-liquid dispensing nozzle 60 is attached to the injection port main body 41 of the injection port 40 installed in the opening 5a of the outer casing 5. In this case, the spout upper member 70 has the external thread 70a, and the spout body 41 has the internal thread 41a. The external thread 70a is engaged with the internal thread 41a, so that the spout upper member 70 is fixed to the spout body 41. Inside. The liquid dispensing nozzle 60 is screwed to the spout upper member 70 by engaging the external thread 60a of the liquid dispensing nozzle 60 with the internal thread 70b of the spout upper member 70.

The liquid dispensing nozzle 60 inserted into the spout upper member 70 is a bag that penetrates the through hole 45 of the spout 40 toward the liquid storage container 1. The body 3 extends (refer to Fig. 1). Further, the liquid dispensing nozzle 60 has a dome-shaped portion 61 formed at a lower end thereof, and a plurality of openings 62 are formed in the dome-shaped portion 61. The dome-shaped portion 61 is formed in a hemispherical shape, and a plurality of openings 62 are formed in the hemispherical surface. The dome-shaped portion 61 may have a hemispherical shape at the lower end of the liquid dispensing nozzle 60 or a hemispherical nozzle cap may be attached to the lower end of the liquid dispensing nozzle 60.

Next, the content liquid in the liquid storage container 1 is discharged to the outside. In this case, the liquid dispensing nozzle 60 is connected to the dispenser through the connecting tube 63.

Next, the nitrogen gas is supplied from the pressurized gas source (not shown) to the injection port body 41 of the injection port 40, and thereafter the nitrogen gas is introduced into the outer container 5 and the bag body of the liquid storage container 1 from the opening 44. The space between 3. Then, the bag body 3 is pressed by the nitrogen gas from the outside, and the content liquid in the bag body 3 enters the liquid dispensing nozzle 60 from the opening 62 of the dome-shaped portion 61, so that the content liquid in the liquid dispensing nozzle 60 is removed from the liquid. Thereafter, the connecting rigid tube 63 is discharged toward the dispenser side. Alternatively, a suction pump (not shown) may be connected to the injection port 40, and the discharge generated by the suction pump may be performed. At this time, the bag body 3 is shrunk as it is discharged, and since the outer side of the bag body 3 is maintained at atmospheric pressure, the outer container 5 is not deformed or the like even if it is not a pressure-resistant container.

Here, since the liquid dispensing nozzle 60 has the dome-shaped portion 61 at the lower end thereof, the liquid in the bag body 3 is discharged from the connecting tube 63 to the outside through the liquid dispensing nozzle 60, and the liquid dispensing nozzle 60 is disposed. Even if the lower end abuts against the inner surface of the bag body 3, it can be prevented from being The lower end of the liquid dispensing nozzle 60 breaks the bag body 3.

Further, the content liquid in the bag body 3 is sucked into the liquid dispensing nozzle 60 through the plurality of openings 62 provided in the dome-shaped portion 61, and is discharged from the connecting tube 63 toward the dispenser side. Therefore, even if the residual amount of the content liquid is reduced as compared with the case where a single opening is provided in the center of the lower end of the liquid dispensing nozzle 60, the bag body 3 can be in close contact with the liquid dispensing nozzle 60 to prevent the content liquid from being easily distributed toward the liquid dispensing nozzle 60. Flow inside.

According to the present embodiment, the injection port 40 can be installed in the opening portion 5a of the outer container 5 through the holder 80 at the time of filling the content liquid and the discharge of the content liquid, and can be installed in the outer container. The injection port 40 of the opening 5a of the fifth portion 5 removes the holder 80 and conveys the outer container 5, so that the outer container 5 can be conveyed with a light weight. In the case where the outer casing 5 is transported while the holder 80 is attached to the opening 5a, it is necessary to use the holder 80 having a large strength. However, since the holder 80 is removed from the injection port 40 during transportation, the holder 80 is not It is necessary to use a sturdy construction.

Further, when the holder 80 is a two-division structure shown in FIGS. 23A and 23B, the holder 80 can be easily and easily attached to the spout 40, or the holder 80 can be held from the spout 40. Remove the job.
