  Below, the 1st and 2nd embodiment concerning the present invention is described in detail based on a drawing.

(First embodiment)
The accommodation bag 1 concerning 1st Embodiment of this invention is demonstrated using FIG. 1A-1E. Drawing 1A-1E is a schematic diagram of storage bag 1 concerning a 1st embodiment. The storage bag 1 shown in FIGS. 1A to 1E is a sheet-like bag for storing the storage container 5. 1A to 1C show a state where the storage container 5 is not accommodated (FIG. 1B is a developed view), and FIGS. 1D and 1E show a state where the preservation container 5 is accommodated. As the shape of the storage container 5 accommodated in the accommodation bag 1, a substantially cylindrical shape is mainly assumed. In addition, as a target to be stored in the storage container 5, various biological substances such as DNA and cells are mainly assumed. When storing such a biological substance, it is required to store it under a low temperature environment such as freezing or refrigeration and in a state that does not leak to the surroundings. The biological substances in this specification include, for example, blood components (blood, umbilical cord blood, erythrocytes, etc.), body fluids (bone marrow fluid, etc.), cells (germ cells, iPS cells, ES cells, stem cells, rare cells, etc.). , DNA, RNA, virus, bacteria and the like.

  The storage bag 1 in the first embodiment is formed by bending a single sheet-like member a plurality of times. Specifically, first, the sheet-like members shown in FIG. 1B are bent so as to be arranged facing each other as shown in FIG. 1A. Furthermore, the both ends along the longitudinal direction A of the sheet-like members (the first sheet-like member 7 and the second sheet-like member 8) arranged to face each other are joined. That is, both ends of the first and second sheet-like members 7 and 8 in the short direction B are joined to each other along the longitudinal direction A of the first and second sheet-like members 7 and 8. 1A to 1E, the boundary of the joint 6 is represented by a two-dot chain line.

  The storage bag 1 configured as described above includes an opening 2, a bottom 3, and a folded portion 4, as shown in FIGS. 1A and 1C.

  The opening 2 corresponds to one end in the longitudinal direction A of the first and second sheet-like members 7 and 8 in which openings for inserting the storage container 5 are formed. To form the opening 2, as shown in FIG. 1B, both end portions 2a and 2b in the longitudinal direction A of the sheet-like member (one end 2b of the first sheet-like member 7 and one end 2a of the second sheet-like member 8). Are overlapped so as to face each other as shown in FIG. 1A. The first and second sheet-like members 7 and 8 are joined to each other at both ends in the short direction B of the opening 2 to form a joined portion 6. In this way, the joints 6 are provided at both ends of the opening 2, and the joint 6 is not provided at the center of the opening 2, thereby opening the center of the opening 2 and inserting the storage container 5. An opening is formed.

  The bottom part 3 is a part which supports the bottom face of the storage container 5 inserted into the storage bag 1 (see FIGS. 1D and 1E). As shown in FIG. 1A, the bottom 3 corresponds to the other end of the first and second sheet-like members 7 and 8 in the longitudinal direction A. In order to form the bottom part 3, as shown in FIG. 1B, it is bent along a line 3a extending in the short direction B of the sheet-like member (arranged so that the first sheet-like member 7 and the second sheet-like member 8 face each other). At the same time, both end portions along the longitudinal direction A of the first and second sheet-like members 7 and 8 are joined to each other at the bent portions to form the joint portion 6. Thereby, the bottom part 3 is formed.

  The folded portion 4 is a portion formed by folding the sheet-like member between the opening 2 and the bottom portion 3 so as to protrude outward. Specifically, as shown in FIGS. 1A to 1C, on one side (first sheet-like member 7) of the opposing sheet-like member, the first sheet-like member 7 is folded back so as to protrude outward. Has been. More specifically, as shown in FIG. 1B, the folded portion 4 is formed by bending the first sheet-like member 7 along each of three lines (first line 4a to third line 4c) extending in the short direction B. Is forming. As shown in FIGS. 1A and 1C, these lines have inner ends as the first line 4a and the third line 4c that are closest to the second sheet-like member 8 in the folded portion 4 (ie, the inner side). The second line 4b corresponds to an outer end portion as a side (that is, an outer side) farthest from the second sheet-like member 8 in the folded portion 4. In addition, the both ends along the longitudinal direction A of the 1st sheet-like member 7 in the folding | returning part 4 are also mutually joined, and the junction part 6 is formed (refer FIG. 1B).

  The folding | returning part 4 in 1st Embodiment is folded so that it may protrude toward the opening part 2 side, as shown to FIG. 1A and 1C. That is, as shown in FIG. 1C, the direction in which the folded portion 4 protrudes is inclined from the direction D perpendicular to the longitudinal direction A of the entire sheet-like member toward the opening 2 side. In other words, the folded portion 4 is folded so that the inner opening formed by the folding is opened toward the bottom 3 side of the containing bag 1. In order to determine such a folding direction of the folded portion 4, it can be determined by pressing the folded portion 4 while directing the folded bag 4 when the containing bag 1 is manufactured.

  The folding | returning part 4 mentioned above has a function which maintains the storage container 5 in an accommodation space (it makes it difficult to pull out) when the storage container 5 is accommodated so that it may mention later. Accordingly, the position of the folded portion 4 (position in the longitudinal direction A of the sheet-like member) is a position where the storage container 5 can be accommodated between the folded portion 4 and the bottom portion 3 (that is, a position sufficiently separated from the bottom portion 3). ).

  In addition, the folding | returning part 4 in this specification is the part turned up so that one sheet-like member might overlap at least twice.

  As described above, the joint portion 6 is provided at the end portion (end portion in the short direction B) along the longitudinal direction A on the surfaces of the first and second sheet-like members 7 and 8 facing each other. . Moreover, the junction part 6 in 1st Embodiment is provided over the full length of the longitudinal direction A in the surface of the side which the 1st, 2nd sheet-like members 7 and 8 oppose, as shown to FIG. 1B. In the accommodation bag 1 shown in FIG. 1A, only the opening 2 is opened by providing the joining portion 6 over the entire length in the longitudinal direction A on the opposing surfaces of the first and second sheet-like members 7 and 8. However, the other parts are joined by the joining part 6 to form a closed structure.

  The joint portion 6 is provided only on the inner side (back side) where the first and second sheet-like members 7 and 8 are opposed to each other, and is provided on the outer side (front side) that is not opposed to each other and exposed to the outside. Absent. For example, the second line 4b to the third line 4c shown in FIGS. 1A and 1C and the part from the third line 4c to the end 2b of the sheet-like member are not joined to each other. That is, in the 1st sheet-like member 7, the part except the 1st folding | turning part 4 and the 1st folding | turning part 4 is not mutually joined.

  In the first embodiment, as a sheet-like member constituting the containing bag 1, a structure having two layers of an EFEP layer and a polyimide layer is employed. EFEP is a fusible substance, and polyimide is a non-fusible substance. In the first embodiment, the sheet-like member having such a structure is arranged such that the polyimide layer is exposed to the outside and the EFEP layer is located on the inside. That is, the EFEP layer disposed on the inner side is fused and joined to form the joint portion 6 of the sheet-like member, while the polyimide layer disposed on the outer side is not fused or joined. By such arrangement | positioning, the structure of the accommodation bag 1 which forms the junction part 6 only in the inner side of a sheet-like member, and does not form in the outer side is implement | achieved more simply. The structure is particularly excellent in terms of resistance to extremely low temperatures, and has resistance to a temperature of −196 ° C., which is the boiling point of liquid nitrogen, for example.

  In such a configuration, the operation and effect when the substantially cylindrical storage container 5 is accommodated in the accommodation bag 1 will be described with reference to FIGS. 1D and 1E.

  When inserting the storage container 5 into the storage bag 1, first, the storage container 5 is inserted into the storage bag 1 from the lower part (bottom) of the storage container 5 through the opening 2. Thereafter, the storage container 5 is pushed in along the longitudinal direction A of the storage bag 1, so that the upper part (top) of the storage container 5 reaches and passes through the folded part 4. At the same time, the lower part of the storage container 5 reaches the bottom 3 of the storage bag 1. Thus, the storage container 5 is held between the bottom part 3 and the folded part 4, and an accommodation space for accommodating the storage container 5 is formed between the bottom part 3 and the folded part 4.

  By inserting the storage container 5, as shown in FIGS. 1D and 1E, the sheet-like member from the folded-back portion 4 to the bottom portion 3 is expanded along the radial direction of the storage container 5. Moreover, as shown to FIG. 1D, the part containing the 3rd line 4c which is the inner side edge part of the folding | returning part 4 will be in the state which contacted the upper part of the storage container 5. FIG. In such a state, the storage container 5 is accommodated in the accommodation bag 1.

  After the storage container 5 is stored, the inside of the storage bag 1 can be sealed by performing sealing (sealing) at a position from the folded portion 4 to the opening 2. That is, the storage container 5 can be stored in a sealed and sealed state in the storage bag 1.

  As described above, when the storage container 5 is inserted into the storage bag 1 and stored in the storage space between the folded portion 4 and the bottom portion 3, the folded portion 4 is expanded in the radial direction of the storage container 5. It becomes a state. As shown in FIG. 1D, the folded portion 4 in such a state acts to maintain the storage container 5 in the accommodation space (to make it difficult to remove). Further, the folded portion 4 acts so as to divide the bottom 3 side portion (lower portion) from the folded portion 4 and the opening 2 side portion (upper portion) located on the opposite side. .

  According to such an effect | action, the storage bag 1 can be easily sealed in the area | region from the folding | turning part 4 to the opening part 2 in the state which accommodated the storage container 5 in the storage bag 1. FIG. Furthermore, since the length of the 1st, 2nd sheet-like members 7 and 8 from the folding part 4 to the opening part 2 can be shortened compared with the case where the folding part 4 is not provided, The amount used can be reduced. This effect is particularly effective when an expensive material such as the above-described structure of two layers of EFEP and polyimide is used. Further, since the height of the storage bag 1 in the standing posture can be reduced, when storing the storage bag 1 in a state of storing the storage container 5 in the box while standing, the box (the lid of the box) and the upper end of the storage bag 1 are stored. Interference can be suppressed. Thereby, the storage bag 1 and the storage container 5 can be stored in a more stable state. Furthermore, since the storage bag 1 can be easily sealed by the folded-back portion 4, a more reliable sealing operation can be realized, so that the sealing performance and sealing performance of the storage bag 1 can be improved.

  As described above, according to the storage bag 1 according to the first embodiment, the first sheet-like member 7 is formed with the folded portion 4 that is folded back so as to protrude outward, and the first sheet-like shape in the folded portion 4. Both end portions along the longitudinal direction A of the member 7 are joined, and the storage container 5 is accommodated between the folded portion 4 and the bottom portion 3. As a result, when the storage container 5 is accommodated between the folded portion 4 and the bottom portion 3, the folded container 4 keeps the storage container 5 in the accommodation space (makes it difficult to come off), and the bottom portion 3 with reference to the folded portion 4. The region on the side and the region on the opening 2 side are divided. By such an action, the containing bag 1 can be easily sealed in the region from the folded portion 4 to the opening 2.

  Moreover, according to the storage bag 1 of 1st Embodiment, the folding | returning part 4 is provided in the position which positions the storage container 5. As shown in FIG. Specifically, the folding part 4 in the first embodiment is provided at a position where the folding part 4 contacts the upper part of the storage container 5 when the lower part of the storage container 5 reaches the bottom part 3. That is, in a state where the storage container 5 is accommodated between the folded portion 4 and the bottom portion 3, the folded portion 4 acts to press the storage container 5 toward the bottom portion 3 and position the storage container 5 in the accommodation space. . Thereby, the storage container 5 can be accommodated in the accommodation bag 1 in a more stable state.

  Furthermore, according to the storage bag 1 of the first embodiment, the sheet-like member has a two-layer structure of an EFEP layer and a polyimide layer, the polyimide layer is exposed to the outside, and the EFEP layer is fused on the inside to join. Are arranged to be. Such a two-layer structure of an EFEP layer and a polyimide layer is excellent in resistance to cryogenic temperatures. Therefore, particularly when storing the storage container 5 for frozen storage or refrigeration storage, the storage container 5 and its contents are more Can be properly protected.

  Moreover, according to the storage bag 1 of 1st Embodiment, the folding | turning part 4 is formed only in the one side (1st sheet-like member 7) of the sheet-like members which oppose. That is, the second folded portion 8 is not formed with a folded portion that is folded back so as to protrude outward. With such a configuration, compared to the case where the folded portions are formed on both sides of the first and second sheet-like members 7 and 8 that face each other, the thickness (in the direction D shown in FIG. Difference in thickness) can be suppressed to an appropriate level. Therefore, when manufacturing the storage bag 1, formation of the junction part 6 etc. can be performed more easily.

  Moreover, according to the storage bag 1 of 1st Embodiment, the folding | returning part 4 is folded so that it may protrude toward the opening part 2 side. According to such a configuration, the folded portion 4 is less likely to become an obstacle when the storage container 5 is inserted, as compared with the case where the folded portion 4 is folded back so as to protrude toward the bottom portion 3 side. Can be inserted smoothly.

  Moreover, according to the storage bag 1 of 1st Embodiment, the junction part 6 of the 1st, 2nd sheet-like members 7 and 8 mutually opposes among the surfaces of the 1st and 2nd sheet-like members 7 and 8. It is provided over the entire length in the longitudinal direction A on the side surface. Thereby, the sealing performance and sealing performance of the storage bag 1 can be improved.

(Second Embodiment)
Next, the accommodation bag 10 concerning 2nd Embodiment of this invention is demonstrated using FIG. 2A-2E. 2A to 2C show a state where the storage container 5 is not accommodated (FIG. 2B is a developed view), and FIGS. 2D and 2E show a state where the preservation container 5 is accommodated.

  In the second embodiment, compared to the first embodiment, only the shape of the bottom 13 of the storage bag 10 formed by the first and second sheet-like members 17 and 18 is different, and the other shapes and the like are the first. Since it is the same as that of the embodiment, the description thereof will be omitted, and the description will focus on the differences.

  As shown in FIGS. 2A and 2C, the bottom 13 according to the second embodiment folds the connecting portions (corresponding to the line 3a in the first embodiment) of the first and second sheet-like members 17 and 18 inward. It is formed with. Specifically, the sheet-like member of the bottom portion 13 is bent along each of three lines (first line 13a to third line 13c) extending in the short-side direction B so as to be separated into two forks. A bottom 13 is formed. As shown in FIG. 2A, the first line 13 a corresponds to the outer end where the second sheet-like member 18 is located on the outermost side in the bottom portion 13, and the second line 13 b is the first and second sheet-like members 17. , 18 corresponds to the inner end portion located on the innermost side in the bottom portion 13, and the third line 13 c corresponds to the outer end portion on which the first sheet-like member 17 is located on the outermost side in the bottom portion 13.

  According to such a configuration, the folded portion 4 formed by folding the first sheet-like member 17 outward between the opening 2 and the bottom portion 13 is provided as the first folded portion 4. A portion formed by folding the first and second sheet-like members 17 and 18 inward is provided as a second folded portion 13 (bottom portion 13).

  In such a configuration, the operation and effect when the storage container 5 is stored in the storage bag 10 will be described with reference to FIGS. 2D and 2E.

  When the storage container 5 is inserted from the opening 2 and the lower part of the storage container 5 reaches the bottom part 13 as shown in FIGS. 2D and 2E, the bottom part 13 is moved in the radial direction of the storage container 5 by the lower part of the storage container 5. Can be spread. The storage container 5 is housed in a housing space having a generally rectangular cross section as shown in FIG. 2D between the first folded portion 4 and the second folded portion 13. At this time, the storage space is formed by the sheet-like member extending in the radial direction of the storage container 5 both above and below the storage container 5. Thereby, the storage container 5 can be accommodated in a more stable state in the accommodation space.

  In such a state, the 2nd folding | turning part 13 which spread by insertion of the storage container 5 becomes a shape which can become independent, as FIG. 2D and 2E show. Specifically, the first line 13a and the third line 13b arranged substantially symmetrically with the second line 13b as the center are used as mounting points, so that the shape can be stably independent. In this way, the storage bag 10 can be configured to be self-supporting in a state where the storage container 5 is stored. When the target object stored in the storage container 5 is a biological substance or the like, it is preferable to store the storage container 5 in an upright state from the viewpoint of preventing leakage. On the other hand, the storage bag 10 according to the second embodiment has a structure that allows the storage bag 10 to stand on its own in a state where the storage container 5 is stored. Therefore, the storage container 5 can be stored in an upright state by the storage bag 10 itself without separately providing a holding tool for holding the storage bag 10. Thereby, the handleability of the storage bag 10 can be improved.

  Also in the second embodiment, the first folding part 4 is a position where the storage container 5 is positioned, that is, a position where the lower part of the storage container 5 comes into contact with the upper part of the storage container 5 when it reaches the bottom 13. Is provided. By such setting of the position of the first folding part 4, the upper part of the storage container 5 is allowed to reach and pass the first folding part 4 and at the same time, the lower part of the storage container 5 reaches the bottom part 13 (second folding part 13). Thus, the second folded portion 13 extends in the radial direction of the storage container 5, so that the containing bag 1 can stand on its own. In this way, the storage container 5 can be stored more efficiently by performing the storage operation of the storage container 5 in conjunction with the first folding part 4 and the second folding part 13.

  In the second embodiment, since the storage container 5 is positioned by combining the two folded portions of the first folded portion 4 and the second folded portion 13, the height of the storage container 5 is determined with respect to the positioning of the storage container 5. Positioning can be stably performed not only in the direction but also in the radial direction (see FIG. 2D). Thereby, the storage container 5 can be stored in a more stable state.

  That is, according to the storage bag 1 according to the second embodiment, a particularly advantageous effect can be exhibited from the viewpoint of storage of the storage container 5.

  As described above, according to the storage bags 1 and 10 according to the first and second embodiments, the storage container 5 has a simple structure by using the folded portion formed by folding the sheet-like member. The storage bags 1 and 10 can be more easily sealed after the storage.

  Next, what is marketed on the market as the storage container 5 accommodated in the accommodation bags 1 and 10 is illustrated below. All of these are generally cylindrical storage containers 5.

(Example 1)
Outer diameter: φ12.5mm
Height: 42mm, 43mm, 46mm, 48mm, 70mm, 71mm, 90mm

(Example 2)
Outer diameter: φ10.5mm
Height: 46mm

(Example 3)
Outer diameter: φ12.5mm
Height: 42mm, 48mm, 49mm, 70mm, 72mm, 92mm

(Example 4)
Outer diameter: φ12.5mm
Height: 48mm, 70mm, 92mm

  For the storage bag 10 according to the second embodiment, the above-described variation in the size of the storage container 5 can be dealt with by the following three size patterns, for example.

(Pattern 1: Corresponding to the type in which the height of the storage container 5 is 42 mm-49 mm)
Total length of the sheet-like member in the longitudinal direction A: 177 mm
Total length of sheet member in short direction B: 32 mm
Length of holding part of sheet-like member: 50mm

(Pattern 2: Corresponding to the type in which the height of the storage container 5 is 70 mm-72 mm)
Total length of the sheet-like member in the longitudinal direction A: 223 mm
Total length of sheet member in short direction B: 32 mm
Length of holding part of sheet-like member: 73mm

(Pattern 3: Corresponding to the type of storage container 5 with a height of 90 mm-92 mm)
Total length of the sheet-like member in the longitudinal direction A: 263 mm
Total length of sheet member in short direction B: 32 mm
Length of holding part of sheet-like member: 93mm

  Here, regarding the pattern 1-3, attention is paid to the length of the holding portion of the sheet-like member and the height of the corresponding storage container 5. Here, the “length of the sheet-like member holding portion” is the length from the outer end portion 4b of the first folded portion 4 to the outer end portion 13c of the second folded portion 13 as shown in FIGS. 2C and 2D. It means the direction length L. In the pattern 1, the length L of the holding portion of the sheet-like member is 50 mm with respect to the height of the storage container 5 of 42 mm-49 mm. In the pattern 2, the length L of the holding portion of the sheet-like member is 73 mm with respect to the height 70 mm to 72 mm of the storage container 5. In the pattern 3, the length L of the holding portion of the sheet-like member is 93 mm with respect to the height 90 mm to 92 mm of the storage container 5.

  That is, in any pattern, the length L of the holding portion of the sheet-like member is set within a range of 100% to 120% with respect to the height of the storage container 5. Thereby, holding | suppressing and positioning of the storage container 5 by the folding | returning part 4 can be performed appropriately.

  In this way, the length L of the holding portion of the sheet-like member (the length L in the longitudinal direction A from the outer end portion 4b of the first folded portion 4 to the outer end portion 13c of the second folded portion 13) is determined as the storage container. The first folded portion 4 may be set to a position where the storage container 5 is pressed and positioned by setting it to be approximately equal to the height of 5 (for example, within a range of 100% to 120%).

  In addition, this invention is not limited to the said embodiment, It can implement with another various aspect. For example, in the first and second embodiments, the case where the sheet-like member has a two-layer structure of the EFEP layer and the polyimide layer has been described, but the material and the number of laminated sheets are not limited thereto. For example, a single layer or a structure of three or more layers may be adopted. In the case of a multilayer structure of two or more layers, for example, with respect to the outermost layer exposed to the outside and the innermost layer material that is disposed on the inner side and joined, the melting point of the outermost layer material is the melting point of the innermost layer material. The material of each layer may be selected so as to be higher. By selecting a material using such a difference in melting point (for example, thermoplastic resin), the same structure as in the first and second embodiments in which the outside of the sheet-like member is not fused but the inside is fused, It can be realized without being limited to EFEP and polyimide. For example, a polyamide (melting point is 225 ° C., for example), which is a substance having a high melting point, is adopted as the material of the outermost layer, and a polyethylene (melting point, eg, 120 ° C.), which is a substance having a low melting point, is adopted as the material of the innermost layer By heating at a temperature of about 190 ° C., the outermost polyamide layer can be fused and the innermost polyethylene layer can be fused.

  In the above description, the case where one folded portion 4 is provided only on one side of the facing sheet-like member has been described. However, the present invention is not limited to such a case. For example, the folded portions 4 may be provided on both sides of the facing sheet-like member.
