<First embodiment of the present invention>
The first embodiment of the present invention will be described below with reference to the drawings.
Here, FIG. 1 to FIG. 18 are diagrams showing an embodiment of the present invention.

First, the liquid storage container 1 will be described.
The liquid storage container 1 includes a multi-layer film 2 in which an outer bag 20 and an inner bag 21 are overlapped so that the inner bags 21 face each other to form a total of four sheets. 10, and a spout 40 disposed on the upper edge 3 a of the bag body 3 and heat-sealed in advance between the inner bags 21.

  In this embodiment, the bag body 3 is obtained by laminating the multiple films 2 so that the inner bags 21 face each other, and heat-sealing the four sides to form the heat-seal portion 10, but this is not limitative. For example, after the multiple film 2 is folded so that the inner bags 21 face each other, the three outer peripheral sides that overlap each other may be heat-sealed. Moreover, you may form each inner edge part of the heat seal part 10 so that the inner edge may become arc shape. As a result, a structure in which the fluid content hardly remains at the corners is obtained. Moreover, the bag body does not necessarily need to be composed of multiple films, and the film structure of the bag body 3 can be appropriately selected according to the contents and quantity.

  In the present embodiment, an example is shown in which the bag body 3 is formed in a form in which two multiplex films are overlapped. However, the present invention is not limited to this, and two films are prepared and four sides are heat sealed. Alternatively, the bag body 3 can be formed of a single layer film by folding a single film and heat-sealing three sides.

  Note that, as described above, the bag body 3 is obtained by stacking the two multiple films 2 and heat-sealing the periphery to form the heat seal portion 10. In this case, the bag body 3 has a rectangular shape having an upper edge 3a, a bottom edge 3b, and two side edges 3c, 3c. The upper edge 3a includes two upper edge heat seal portions 10a, the bottom edge 3b includes one bottom edge heat seal portion 10b, and each side edge 3c, 3c has one side edge heat seal portion 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.

  Moreover, in this Embodiment, although the upper edge 3a of the bag main body 3 contains the two upper edge heat seal parts 10a as mentioned above, you may form one heat seal part in the upper edge 3a. By dividing the heat seal portion 10a of the upper edge 3a into two as in this embodiment, for example, one heat seal portion having a width of two heat seal portions 10a is formed on the upper edge 3a. Compared to the case, the upper edge 3a can be made relatively soft.

  The spout 40 includes a spout attachment part 50 that is heat-sealed to the upper edge 3a of the bag body 3 and a spout body 41 that is connected to the spout attachment part 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. 1, the spout 40 is heat-sealed between the inner bags 21 of the multiplex film 2 at the spout attachment portion 50.

  As shown in FIGS. 2 to 7, the spout mounting portion 50 of the spout 40 is an elliptic cylinder having a central portion 51 and thin portions 52 which are provided on both sides of the central portion 51 and are thinner than the thickness of the central portion 51. The body is flat and has a through hole 45 in the central portion 51. Usually, when the spout 40 is heat-sealed between the inner bags 21 of the multiplex film 2 at the spout mounting portion 50, there is a gap between two regions surrounded by the inner bag 21 and the end of the spout mounting portion 50. It is easy to become poorly sealed. In order to prevent this, thin portions 52 are provided on both sides, and a gap is prevented by melting the thin portions 52 during heat fusion.

  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. Further, a spout upper member 70 is provided at the bottom 43 in the spout main body 41 so as to extend in the vertical direction.

  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.

  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, since the resin constituting the inner surface of the inner bag 21 of the multiplex film 2 is bonded by thermal fusion, Although it is necessary to select appropriately depending on the resin constituting the inner surface, high-density polyethylene that is rigid at high temperatures and hardly brittle at low temperatures is preferable.

  As shown in FIG. 9, a laminate of unstretched nylon (thickness 20 μm) 20 a / linear low density polyethylene (thickness 40 μm) 20 b can be used as the outer bag 20 of the bag body 3. As this, linear low density polyethylene (thickness 70 μm) can be used.

  In this case, since the outer bag 20 includes the unstretched nylon 20a, the degree of elongation of the outer bag 20 can be increased. For example, the outer bag 20 has a degree of elongation of 300% to 500%. Thus, since the outer bag 20 can have a high degree of elongation, the bag body 3 can be made soft as a whole, and the bag body 3 is inserted into the outer container 5 as will be described later. When the bag body 3 is inflated in the outer container by supplying nitrogen gas or clean dry air into the inside, the bag body 3 can be smoothly inflated.

  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 inner bag 21, materials such as low density polyethylene, low density polyethylene and linear low density polyethylene can be used.

  As the material of the outer bag 20, a material having an elongation of 300% to 500%, such as 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.

Next, the holder 80 will be described in detail with reference to FIGS. 10A 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 a ring shape that forms an opening 80a, and the inner diameter thereof is a1. The inner flange 82 is provided with a pair of opposed notches 85, 85 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 (see FIG. 10A and FIG. 10B).

  For this reason, 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 configured in this manner is attached to the spout 40 of the liquid storage container 1 (see FIGS. 11 to 13). In this case, the spout flange 42 of the spout 40 has a ring shape (circular shape). I am doing. Therefore, the maximum outer diameter b1 and the minimum outer diameter b2 of the spout flange 42 are equal to each other (see FIG. 4).

  However, the spout flange 42 may be formed in an elliptical shape, and the spout flange 42 may have a maximum outer diameter b1 and a minimum outer diameter b2 smaller than the maximum outer diameter (two-dot chain line in FIG. 4). reference).

  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 spout funnel 42 of the spout 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 spout flange 42, and a2> b2.

  The minimum inner diameter a1 of the inner flange 82 is smaller than the maximum outer diameter b1 of the spout flange 42, and a1 <b1.

  Since a2> b2 as described above, the spout flange 42 can pass through a space extending between the pair of notches 85 of the holder 80. Further, since a1 <b1, the spout flange 42 that has passed between the pair of notches 85 of the holder 80 can be locked to the inner flange 82 of the holder 80.

    By the way, 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 spout flange 42 of the spout 40 can be defined 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 opposing points of the inner edge 82A of the inner flange 82, and the maximum inner diameter a2 of the inner flange 82 of the holder 80 is It is the maximum length of a straight line connecting two facing points of the inner edge 82A of the inner flange 82.

  The maximum outer diameter b1 of the spout flange 42 of the spout 40 is the maximum length of a straight line connecting the two opposite points of the outer edge 42A of the spout flange 42, and the minimum of the spout flange 42 of the spout 40 The outer diameter b <b> 2 is the minimum length of a straight line connecting the two opposing points of the outer edge 42 </ b> A of the spout flange 42.

  Here, “between two points facing each other” that defines the above a2 and b2 means that the spout flange 42 smoothly passes through the space in the holder 80 using the two points facing each other.

  The “between two points facing each other” defining the above a1 and b1 means that the spout flange 42 can be engaged with the inner flange 82 of the holder 80 using the two points facing each other.

Next, the operation of the present embodiment having 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 vertical direction and formed in an elongated shape in the vertical direction, and the liquid storage container 1 is inserted into the exterior container 5 from the opening 5a.

  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, the spout 40 is first inclined with respect to the holder 80 as shown in FIG. In FIG. 18, the spout 40 is tilted 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, the maximum inner diameter a2 of the inner flange 82 corresponding to the pair of notches 85 is larger than the minimum outer diameter b2 of the outlet flange 42 corresponding to the ring-shaped outer diameter. The space extending between the notches 85 can be smoothly passed. 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. 11 to 17).

  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.

  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. 6 and 7).

  By the way, as the exterior container 5 shown in FIG. 8, a rectangular cylindrical large synthetic resin container (capacity 1000 kg) can be used, but a cylindrical container may be used as the exterior container 5.

  Alternatively, as the outer container 5, a metal canister can, a synthetic resin drum can, or a metal container can 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.
Next, 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. Along with this, the bag body 3 folded in the vertical direction is expanded flat.

  In addition, since the upper edge 3a of the bag body 3 includes the two upper edge heat seal portions 10a, the upper edge 3a can be configured to be softer than the case of including a wide heat seal portion, and the bag body 3 can be made more flexible. It can be smoothly expanded in the outer container 5. Furthermore, 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 enhanced and the expansion action of the bag body 3 can be easily performed.

  In this way, a combined body of the exterior container and the liquid storage container 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 content liquid is filled into the liquid storage container 1, as shown in FIGS. 6 and 7, the liquid distribution nozzle 60 is previously placed in the spout body 41 of the spout 40 attached to the opening 5 a of the outer container 5. The spout upper member 70 that holds the screw is attached. In this case, the spout upper member 70 has an external thread 70a, the spout body 41 has an internal thread 41a, and the external thread 70a is engaged with the internal thread 41a, so that the spout body 41 has a spout. The upper member 70 is fixed. Further, the liquid distribution nozzle 60 is screwed and fixed to the spout upper member 70 by engaging the outer screw 60 a of the liquid distribution nozzle 60 with the inner screw 70 b of the spout upper member 70.

  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 (see FIG. 1). The liquid distribution nozzle 60 has a dome-shaped portion 61 formed at the lower end thereof, and a plurality of apertures 62 are formed in the dome-shaped portion 61. The dome-shaped portion 61 has a hemispherical shape, and a plurality of apertures 62 are formed on the hemispherical surface. In the dome-shaped portion 61, the lower end of the liquid distribution nozzle 60 may be formed in a hemispherical shape, or a nozzle cap formed in a hemispherical shape may be attached to the lower end of the liquid distribution nozzle 60.

  Thus, after the filling process of the content liquid into the liquid container 1 is finished, the opening cap 5A is attached to the opening 5a of the outer container 5 (see FIG. 8). In this way, the spout 40 and the liquid distribution nozzle 60 are sealed.

  When the content liquid in the liquid storage container 1 is discharged to the outside, the opening cap 5 </ b> A is removed, and 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 by nitrogen gas from the outside, and the content liquid in the bag body 3 enters the liquid distribution nozzle 60 through the opening 62 of the dome-shaped portion 61, and the content liquid in the liquid distribution nozzle 60 is then connected. It is discharged from the pipe 63 to the dispenser side. 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.

  During this time, since the liquid distribution nozzle 60 has the dome-shaped portion 61 at the lower end thereof, when the content liquid in the bag body 3 is discharged from the connection pipe 63 to the outside through the liquid distribution nozzle 60, the lower end of the liquid distribution nozzle 60 Even if it contacts the inner surface of the bag body 3, the bag body 3 is prevented from being damaged by the lower end of the liquid distribution nozzle 60.

  Further, the content liquid in the bag body 3 is sucked into the liquid distribution nozzle 60 through a plurality of apertures 62 provided in the dome-shaped portion 61 and discharged from the connection pipe 63 to the dispenser side. For this reason, compared with the case where a single opening is provided at the center of the lower end of the liquid distribution nozzle 60, the bag body 3 is in close contact with the liquid distribution nozzle 60 in the liquid distribution nozzle 60 even when the remaining amount of content liquid is reduced. It is prevented that the content liquid becomes difficult to flow.

  As described above, according to the present embodiment, the holder 80 is formed in a ring shape having the outer flange 81 and the inner flange 82. Therefore, for example, the holder 80 is configured in a U shape, or the hinge portion. The holder 80 can be firmly configured as compared with the case where it has a configuration that opens and closes around the center. Further, when the minimum inner diameter of the inner flange 82 of the holder 80 is a1, the maximum inner diameter is a2, the maximum outer diameter of the spout flange 42 of the spout 40 is b1, and the minimum outer diameter is b2, a2> b2. Therefore, since the spout flange 42 is smoothly passed through the inner flange 82 and a1 <b1, the spout flange 42 can be reliably locked to the inner flange 82 thereafter.

<Second Embodiment>
Next, a second embodiment will be described with reference to FIGS. 22A to 26.

  The second embodiment shown in FIG. 22A to FIG. 26 is different from the first embodiment shown in FIG. 1 to FIG. 21C except for the usage of the combination of the outer container and the liquid container. It is.

  In the second embodiment shown in FIGS. 22A to 26, the same parts as those in the first embodiment shown in FIGS. 1 to 21C are denoted by the same reference numerals, and detailed description thereof is 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 vertical direction to be formed in an elongated shape in the vertical direction, and the liquid storage container 1 is inserted into the exterior container 5 from the opening 5a.

  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, the spout 40 is first inclined with respect to the holder 80 as shown in FIG. In FIG. 18, the spout 40 is tilted 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, the maximum inner diameter a2 of the inner flange 82 corresponding to the pair of notches 85 is larger than the minimum outer diameter b2 of the outlet flange 42 corresponding to the ring-shaped outer diameter. The space extending between the notches 85 can be smoothly passed. 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. 11 to 17).

  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.

  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. 6 and 7).

  By the way, as the exterior container 5 shown in FIG. 8, a rectangular cylindrical large synthetic resin container (capacity 1000 kg) can be used, but a cylindrical container may be used as the exterior container 5.

  Alternatively, as the outer container 5, a metal canister can, a synthetic resin drum can, or a metal container can be used.

  Next, as shown in FIG. 22B, an expansion jig 90 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 90, The bag body 3 of the liquid storage container 1 swells in the outer container 5.

Next, the effect | action which expands the liquid storage container 1 in the exterior container 5 is demonstrated below.
Next, 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. Along with this, the bag body 3 folded in the vertical direction is expanded flat.

  In addition, since the upper edge 3a of the bag body 3 includes the two upper edge heat seal portions 10a, the upper edge 3a can be configured to be softer than the case of including a wide heat seal portion, and the bag body 3 can be made more flexible. It can be smoothly expanded in the outer container 5. Furthermore, 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 enhanced and the expansion action of the bag body 3 can be easily performed.

  In this way, a combined body of the exterior container and the liquid storage container is obtained. Thereafter, the inflating jig 90 is removed from the spout 40, the content liquid filling machine 91 is attached to the spout 40, and the content liquid is filled into the liquid storage container 1 from the content liquid filling machine (see FIG. 22C). ).

  In this way, as shown in FIG. 22D, after the inner solution is filled into the liquid storage container 1, the spout cap 40A is attached to the spout 40. The spout cap 40 </ b> A has an external thread that engages with the internal thread 41 a of the spout body 41, and the spout cap 40 </ b> A engages the external thread with the internal thread 41 a of the spout body 41. Is attached to the spout 40 (see FIGS. 6 and 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 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.

  In the present embodiment, the spout 40 is accommodated in the outer container 5 through the opening 5 a, and the spout 40 is placed on the upper surface of the bag body 3 of the liquid container 1. At this time, as will be described later, a tape 95 is provided in advance through the opening 44 of the spout 40, and the upper end of the tape 95 is attached to the back of the top plate of the exterior container 1 via an adhesive portion 95a.

  Next, as shown in FIG. 22F, the opening cap 5A is attached to the opening 5a of the outer container 5, and the outer container 5 is completely sealed. As described above, the holder 80 is removed from the spout 40 of the liquid storage container 1 stored in the outer container 5, and the holder 80 is stored in the content liquid filling place.

  Note that the holding tool 80 attached to the spout 40 does not have to have the structure shown in FIGS. 10A and 10B, and the holding tool 80 passes through the dividing line L as shown in FIGS. 23A and 23B. In other words, it may have a split structure. As shown in FIG. 23A and FIG. 23B, the split-structure holder 80 has an outer layer flange 81 and an inner flange 82, and the inner flange 82 has a vent 82 a formed therein. Moreover, the holder 80 may have a multi-partition structure such as a three-part structure or a four-part structure.

  The vent 82 a ensures ventilation between the liquid storage container 1 and the outer container 5. When the liquid storage container 1 is inflated, nitrogen gas or clean dry air is supplied into the liquid storage container 1, and when the bag body 3 is expanded, the air in the exterior container 5 is exhausted to the outside of the exterior container 5. This exhaust can be performed smoothly. When the content liquid is discharged from the liquid storage container 1, gas is sealed between the liquid storage container 1 and the outer container 5 through the vent 82 a, and pressure is applied from the outside of the liquid storage container 1 to inside the liquid storage container 1. Can be discharged smoothly. 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 resistant container.

  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.

  Next, as shown in FIG. 24, the spout 40 placed on the upper surface of the bag body 3 is pulled up at the transport destination. When filling the content liquid, a tape 95 is provided in advance through the opening 44 of the spout 40, and the upper end of the tape 95 is attached to the back of the top plate of the outer container 5 via an adhesive portion 95a. Grips the tape 95 and pulls up the spout 40, and pulls out the spout 40 outward from the outer container 5 through the opening 5a.

  Thus, the tape 95 having the upper end stuck to the back of the top plate of the outer container 5 functions as a drawing tool for the spout 40.

  Next, a holding tool (additional holding tool) 80 is attached to the spout 40 drawn outward from the opening 5a in the same manner as described above. Thereafter, 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. 6 and 7).

  In addition, although the holder stored at the transport destination is used as the additional holder 80, the holder 80 used at the filling place may be transported and used as it is.

  Thereafter, the spout cap 40 </ b> A 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 5 a of the outer container 5. In this case, the spout upper member 70 has an external thread 70a, the spout body 41 has an internal thread 41a, and the external thread 70a is engaged with the internal thread 41a, so that the spout body 41 has a spout. The upper member 70 is fixed. Further, the liquid distribution nozzle 60 is screwed and fixed to the spout upper member 70 by engaging the outer screw 60 a of the liquid distribution nozzle 60 with the inner screw 70 b of the spout upper member 70.

  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 (see FIG. 1). The liquid distribution nozzle 60 has a dome-shaped portion 61 formed at the lower end thereof, and a plurality of apertures 62 are formed in the dome-shaped portion 61. The dome-shaped portion 61 has a hemispherical shape, and a plurality of apertures 62 are formed on the hemispherical surface. In the dome-shaped portion 61, the lower end of the liquid distribution nozzle 60 may be formed in a hemispherical shape, or a nozzle cap formed in a hemispherical shape may be attached to the lower end of the liquid distribution nozzle 60.

  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 by nitrogen gas from the outside, and the content liquid in the bag body 3 enters the liquid distribution nozzle 60 through the opening 62 of the dome-shaped portion 61, and the content liquid in the liquid distribution nozzle 60 is then connected. It is discharged from the pipe 63 to the dispenser side. 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 resistant container.

  During this time, since the liquid distribution nozzle 60 has the dome-shaped portion 61 at the lower end thereof, when the content liquid in the bag body 3 is discharged from the connection pipe 63 to the outside through the liquid distribution nozzle 60, the lower end of the liquid distribution nozzle 60 Even if it contacts the inner surface of the bag body 3, the bag body 3 is prevented from being damaged by the lower end of the liquid distribution nozzle 60.

  Further, the content liquid in the bag body 3 is sucked into the liquid distribution nozzle 60 through a plurality of apertures 62 provided in the dome-shaped portion 61 and discharged from the connection pipe 63 to the dispenser side. For this reason, compared with the case where a single opening is provided at the center of the lower end of the liquid distribution nozzle 60, the bag body 3 is in close contact with the liquid distribution nozzle 60 in the liquid distribution nozzle 60 even when the remaining amount of content liquid is reduced. It is prevented that the content liquid becomes difficult to flow.

  As described above, according to the present embodiment, when filling the content liquid and discharging the content liquid, the spout 40 is attached to the opening 5a of the outer container 5 via the holder 80 and the opening of the outer container 5 is opened. Since the holder 80 can be removed from the spout 40 attached to the part 5a and the outer container 5 can be transported, the outer container 5 can be compactly transported. In addition, when the outer container 5 is transported with the retainer 80 attached to the opening 5a, it is necessary to use the retainer 80 having a high strength. However, since the retainer 80 is removed from the spout 40 during transport, the retainer 80 is firmly fixed. It is not necessary to use a simple structure.

  Further, when a two-piece structure as shown in FIGS. 23A and 23B is used as the holding tool 80, the work of attaching the holding tool 80 to the spout 40 or removing the holding tool 80 from the spout 40 is easy and simple. Can be done.

  Furthermore, an example in which the spout 40 is placed on the top surface of the bag body 3 in the outer container 5 during conveyance and the spout 40 is pulled out by the tape 95 is shown (see FIG. 24). Since the capacity | capacitance of the bag main body 3 becomes large when filling the content liquid, the operator can easily pull out the spout 40 from the opening 5a without using the tape 95.
