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

  1 to 4 are views showing a first embodiment of a chemical solution storage container and a chemical solution storage device according to the present invention.

  As shown in FIGS. 1 to 3, the chemical solution storage device 1 includes a chemical solution storage container 10 for storing a chemical solution such as an electrolyte solution for a lithium ion battery, and the chemical solution storage container 10 disposed therein. A metal can 2 is provided.

  Among these, the chemical solution storage container 10 stores a chemical solution such as an electrolyte solution for a lithium ion battery. In addition to the electrolyte solution for a lithium ion battery, a chemical solution for resist removal used in a semiconductor manufacturing process, or other chemical solution. Can also be stored.

For example, as the electrolyte solution for lithium ion batteries stored in the chemical solution storage container 10, an organic electrolyte solution containing Li ions such as LiClO ₄ and LiPF ₆ can be used.

  Since such an organic electrolytic solution dislikes moisture, halogen, metal ions, etc., a material that contains as little moisture, halogen, metal ions, etc. as possible is used for the inner bag 11 that stores the organic electrolyte as described later. It is done.

  The metal can 2 has a can body 2A having an upper opening 2C and a lid 2B for sealing the upper opening 2C of the can body 2A. The metal can 2 is made of a stainless steel metal can as a whole. Yes.

  Next, a chemical solution storage container 10 for storing a chemical solution arranged in the metal can 2 will be described with reference to FIGS.

  The chemical solution storage container 10 includes, for example, an inner bag 11 that stores a chemical solution 3 such as an electrolyte for a lithium ion battery, an outer bag 12 that surrounds the inner bag 11, and a spout that extends through the inner bag 11 and the outer bag 12. 15.

  Of these, the spout 15 has a spout main body 15a, a pipe 16 extending from the spout main body 15a into the inner bag 11, and a protruding port 17 projecting outward from the spout main body 15a.

  The spout main body 15a is heat-sealed by a hermetic seal portion 13 formed by integrally sealing the inner bag 11 and the outer bag 12, and the spout 15 is fixed to the inner bag 11 and the outer bag 12.

  In addition, a fixing ring 18 for fixing the spout 15 to the lid 2 </ b> B of the metal can 2 is fitted into the protrusion 17 of the spout 15.

  The inner bag 11 is obtained by preparing a pair of films made of the inner bag material 11A, and heat-sealing the peripheral edges of the pair of films to form the heat seal portion 11a (see FIG. 3A). .

  As the inner bag material 11A, a polyolefin material such as PE or PP can be used. Since the inner bag 11 is a portion that directly touches the chemical solution 3, moisture, halogen, and metal ions that the electrolyte solution for lithium ion batteries dislikes. It is preferable to use a material that does not contain as much as possible, for example, a material with low moisture, low halogen, and low metal ions.

  Further, the chemical solution 3 is stored in the inner bag 11, but the inner bag 11 inner surface is prevented from being damaged even if pressure is applied to the inner bag 11 inner surface from the chemical solution 3 during transportation. The corner 11b has a curved surface.

  That is, the chemical solution storage bag 10 having the inner bag 11 in which the chemical solution 3 is stored is arranged in the metal can 2 to obtain the chemical solution storage device 1. When the chemical solution storage device 1 is conveyed, It is also conceivable that pressure is applied to the inner surface of the inner bag 11 from the stored chemical solution 3.

  In such a case, when the corner 11b of the inner surface of the inner bag 11 has a polygonal shape, when pressure is applied from the chemical 3 to the inner surface of the inner bag 11, local stress is applied to the polygonal corner 11b. It is conceivable that the inner bag 11b is damaged near the corner 11b.

  On the other hand, according to the present invention, the corner 11b of the inner surface of the inner bag 11 is formed of a curved surface. Therefore, even if pressure is applied from the chemical solution 3 to the inner surface of the inner bag 11 during conveyance, the corner formed of the curved surface. The local stress is not generated in the portion 11b, and damage to the inner bag 11 in the vicinity of the corner portion 11b can be prevented.

  The corner portion 11b of the inner bag 11 having such a curved surface can be obtained by forming the heat seal portion 11a so that the corner portion 11b has a curved surface when the inner bag 11 is manufactured.

  Next, the outer bag 12 will be described. The outer bag 12 surrounds the inner bag 11 from the outside and is disposed in the metal can 2, protects the inner bag 11 from the outside, and the impact from the metal can 2 is directly applied to the inner bag 11. It functions so as not to be transmitted.

  For this reason, as the outer bag material 12A for producing the outer bag 12, polyolefin layers such as PE and PP, Al layer, PET layer or ON layer (stretched nylon layer) sequentially arranged from the inside to the outside Is used (see FIG. 3B).

  Among these, the polyolefin layer such as PE and PP functions as a heat seal layer, the Al layer functions as a gas barrier layer, and the PET layer or the ON layer has impact resistance.

  Thus, the material 12A for the outer bag 12 has an excellent impact resistance and gas barrier property as a whole compared with the material 11A for the inner bag 11, while the material 11A for the inner bag 11 is used for the outer bag 12. Compared to the material 12A, it is made of a material having a low water content, a low halogen content, and a low metal ion.

  By the way, the outer bag 12 prepares the surface film 12b, the back film 12c, and a pair of gusset films 12d and 12d which consist of the material 12A for the outer bag 12, and heat seals these periphery, and forms the heat seal part 12a. Is obtained.

  In particular, the outer bag 12 can have a gusset-type outer shape by increasing the area of the heat seal portion 12 a at the bottom 12 e of the outer bag 12. The outer bag 12 having such a gusset-type outer shape can stand by itself at the bottom 12e in the metal can 2.

  Thus, by allowing the outer bag 12 having a gusset-type outer shape to stand by itself in the metal can 2, the chemical solution storage container 10 can be stably disposed as a whole in the metal can 2. For this reason, the chemical | medical solution storage container 10 does not shake or slip | deviate in the metal can 2 at the time of conveyance, and the chemical | medical solution 3 accommodated in the inner bag 11 can be conveyed stably.

  As shown in FIG. 2, a hygroscopic material 30 is enclosed between the inner bag 11 and the outer bag 12. Here, the hygroscopic material 30 is enclosed between the inner bag 11 and the outer bag 12 in a state of being housed in a plurality of hygroscopic bag 30 a having air permeability. As the hygroscopic material 30, for example, silica gel particles can be suitably used.

  Specifically, as shown in FIG. 4, the outer bag 12 is provided with a storage portion 20 that stores the moisture absorbent 30. In the present embodiment, the storage unit 20 is configured by a storage bag 21 configured separately from the inner bag 11 and the outer bag 12. In other words, the absorbent bag 30 a containing the absorbent material 30 is stored in the storage bag 21.

  The storage bag 21 is air permeable to the space between the inner bag 11 and the outer bag 12. In the present embodiment, the storage bag 21 is formed of a material having air permeability. Such a storage bag 21 can be formed of nylon, polyurethane, or the like, for example.

  Next, the operation of the present embodiment having such a configuration will be described.

  First, the manufacturing method of the chemical solution storage container 10 and the chemical solution storage device 1 will be described.

  First, the storage bag 21 is prepared. In this case, a pair of rectangular films for forming the storage bag 21 is prepared, and the three peripheral edges are heat-sealed to form the heat seal portion 21a. Thereby, the storage bag 21 with the remaining periphery opened is obtained.

  Next, the hygroscopic bag 30 a containing the hygroscopic material 30 is inserted into the storage bag 21 from the opening of the storage bag 21.

  Thereafter, when the heat seal portion 12 a is formed on the periphery of the outer bag 12, the opening of the storage bag 21 is heat-sealed integrally with the outer bag 12. As a result, the storage bag 21 can be fixed to the outer bag 12.

  After fixing the storage bag 21 to the outer bag 12, as shown in FIG. 1, the inner bag 11 is inserted into the outer bag 12 having a gusseted outer shape from the upper opening 12f of the outer bag 12.

  Next, the spout 15 is inserted into the inner bag 11 from the upper opening 11 f of the inner bag 11.

  Thereafter, the upper opening 11f of the inner bag 11 and the upper opening 12f of the outer bag 12 are aligned and heat sealed together. As a result, the upper opening 11f of the inner bag 11 and the upper opening 12f of the outer bag 12 are integrally sealed to form the hermetic seal portion 13. At the same time, the spout body 15a of the spout 15 is also heat-sealed integrally with the inner bag 11 and the outer bag 12, and the spout 15 is fixed to the inner bag 11 and the outer bag 12 by the hermetic seal portion 13 (see FIG. 2). .

  Thus, the chemical | medical solution storage container 10 provided with the inner bag 11, the outer bag 12, and the spout 15 is obtained. Next, the chemical container 10 is placed in the can body 2A of the metal can 2 by being inserted from the upper opening 2C, and then the upper opening 2C is sealed by the lid 2B.

  In this case, the fixing ring 18 is not attached to the protrusion 17 of the spout 15 and the protrusion 17 of the spout 15 protrudes upward and outward from the opening 2d at the center of the lid 2B (see FIG. 1 and FIG. 1). Figure 2).

  Next, a fixing ring 18 is fitted into the protruding port 17 of the spout 15 that protrudes from the lid 2B of the metal lid 2, and the spout 15 is fixed to the lid 2B of the metal lid 2 in this way.

  In use, the protrusion 17 of the spout 15 is connected to an external supply mechanism (not shown), and the chemical solution 3 is supplied from the supply mechanism into the inner bag 11.

  Next, the protrusion 17 of the spout 15 is sealed with a cap (not shown), and the chemical solution storage device 1 having the inner bag 11, the outer bag 12, and the metal lid 2 is transported to the destination. Thereafter, the cap is removed from the protrusion 17 of the spout 15 at the transport destination, and the protrusion 17 of the spout 15 is connected to a discharge mechanism (not shown). And by this discharge | emission mechanism, the chemical | medical solution 3 in the inner bag 11 is discharged | emitted outside.

  As described above, according to the present embodiment, the chemical solution storage device 1 for storing a chemical solution is disposed in the metal can 2, the metal can 2, the inner bag 11 that stores the chemical solution 3, and the inner bag 11. A chemical solution storage container 10 having an outer bag 12 that surrounds and a spout 15 that extends through the inner bag 11 and the outer bag 12 is provided. For this reason, it is not necessary to wash | clean the metal can 2 frequently compared with the apparatus which stores the chemical | medical solution 3 directly in the metal can 2, and can reduce expensive washing | cleaning cost.

  Further, it is conceivable that pressure is applied from the chemical liquid 3 to the inner surface of the inner bag 11 during the conveyance of the chemical liquid storage device 1, but the corner 11 b of the inner surface of the inner bag 11 is formed of a curved surface, so Even if pressure is applied to the inner surface, stress is not locally concentrated on the corner 11b, and the inner bag 11 is not damaged in the vicinity of the corner 11b.

  Further, since the material 11A of the inner bag 11 is made of a material having a low water content, a low halogen content, and a low ion content, the chemical solution 3 stored in the inner bag 11 is deteriorated or adversely affected by the inner bag 11. There is no.

  Moreover, since the outer bag 12 has a gusset-type outer shape, the outer bag 12 can be stably placed in the can body 2 </ b> A of the metal can 2. For this reason, the outer bag 12 does not shake or shift in the metal can 2 during the transport of the chemical solution storage container 10.

  Further, since the material 12A of the outer bag 12 is excellent in impact resistance and gas barrier properties, the inner bag 11 is protected from the outside, and the impact from the metal can 2 is not transmitted to the inner bag 11 during transportation. In addition, it is possible to prevent an external atmosphere from entering the chemical solution 3 in the inner bag 11.

  Furthermore, since the hygroscopic material 30 is enclosed between the inner bag 11 and the outer bag 12, the humidity of the space between the inner bag 11 and the outer bag 12 can be reduced, and the inner bag 11 It is possible to prevent the stored chemical solution 3 from deteriorating.

  Furthermore, since the hygroscopic material 30 is stored in the storage unit 20 provided in the outer bag 12, the hygroscopic material 30 is prevented from shaking during transportation so that the hygroscopic material 30 does not impact the inner bag 11. can do. In particular, the hygroscopic material 30 is stored in a storage bag 21 configured separately from the inner bag 11 and the outer bag 12, and the storage bag 21 is fixed to the outer bag 12. It is possible to easily obtain a configuration that prevents the rocking. Further, in order to store the hygroscopic material 30 in the storage unit 20, a plurality of the hygroscopic materials 30 can be arranged at different positions in the space between the inner bag 11 and the outer bag 12. The humidity of the space between the bag 12 can be reduced uniformly.

  Furthermore, the storage bag 21 is air permeable to the space between the inner bag 11 and the outer bag 12. For this reason, even when the moisture absorbent material 30 is stored in the storage bag 21, the moisture in the space between the inner bag 11 and the outer bag 12 can be reduced by the moisture absorbent material 30 stored in the storage bag 21. it can. In particular, since the storage bag 21 is made of a material having air permeability, the storage portion 20 having air permeability can be easily obtained with respect to the space between the inner bag 11 and the outer bag 12.

  In manufacturing the inner bag 11 and the outer bag 12, first, the inner bag 11 made of a cylindrical tube is disposed in the outer bag 12 (see FIG. 6A). Next, the lower openings 11g and 12g of the inner bag 11 and the outer bag 12 are integrally heat-sealed, whereby the lower openings 11g and 12g of the inner bag 11 and the outer bag 12 are sealed, and the bottom seal portion 14 is formed. It is formed (see FIG. 6B).

  Next, the spout 15 is inserted into the inner bag 11 from the upper opening 11 f of the inner bag 11, and the hygroscopic material bag 30 a containing the hygroscopic material 30 is inserted between the inner bag 11 and the outer bag 12. The inserted hygroscopic material bag 30 a is placed on the bottom seal portion 14.

  Thereafter, the upper opening 11f of the inner bag 11 and the upper opening 12f of the outer bag 12 are aligned and heat sealed together. As a result, the upper opening 11f of the inner bag 11 and the upper opening 12f of the outer bag 12 are integrally sealed to form the hermetic seal portion 13. At the same time, the spout 15a of the spout 15 is also heat-sealed integrally with the inner bag 11 and the outer bag 12, and the spout 15 is fixed to the inner bag 11 and the outer bag 12 by the hermetic seal portion 13 (FIG. 6C). reference).

In this case, the inside of the storage bag 21 can be air permeable to the space between the inner bag 11 and the outer bag 12 through the vent 22. Further, in this case, the storage bag 21 can be formed of a material that does not have air permeability, and the range of selection of the material forming the storage bag 21 can be widened. For example, PE, PP, and the like are preferable. Can be used.

Modification 4
Next, a modified example 4 of the chemical solution storage container according to the present invention will be described with reference to FIG.

  In the fourth modification shown in FIG. 8, the same parts as those in the first embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the modified example 4 shown in FIG. 8, the storage unit 20 that stores the hygroscopic material 30 includes a storage space 23 that is partitioned by heat-sealing the outer bag 12. That is, the outer bag 12 is heat-sealed to form the storage portion heat seal portion 23a, and the storage portion heat seal portion 23a defines the storage space 23. Thereby, it can prevent that the moisture absorption material 30 shakes during conveyance.

  A vent hole 24 is provided in the heat seal portion 23a for the storage portion. Thereby, the inside of the storage part 20 can have air permeability with respect to the space between the inner bag 11 and the outer bag 12 through the vent 24.
