以下に、本発明にかかる第１実施形態およびその変形例１−５について、図面に基づいて詳細に説明する。   Below, 1st Embodiment concerning this invention and its modification 1-5 are described in detail based on drawing.

（第１実施形態）
本発明の第１実施形態にかかる収容袋１について、図１Ａ−１Ｃを用いて説明する。図１Ａ−１Ｃは、第１実施形態にかかる収容袋１の概略図である。図１Ａ−１Ｃに示される収容袋１は、保存容器５を収容するためのシート状の袋である。図１Ａ、１Ｂは、保存容器５が収容されていない状態（図１Ｂは展開図）を示し、図１Ｃは、保存容器５が収容された状態を示す（図１ＡのＣ−Ｃ断面に対応）。収容袋１に収容する保存容器５の形状としては、大略円柱形状を主に想定している。また、保存容器５に保存する対象物としては、ＤＮＡや細胞などの各種生体性物質を主に想定している。このような生体性物質の保存時には、冷凍や冷蔵といった低温環境下で、かつ周囲に漏洩しないような状態での保存が求められる。なお、本明細書における生体性物質には、例えば、血液成分（血液・臍帯血・赤血球等）、体液（骨髄液等）、細胞（生殖細胞・ｉＰＳ細胞・ＥＳ細胞・幹細胞・稀少細胞等）、ＤＮＡ、ＲＮＡ、ウィルス、細菌などが含まれる。 (First embodiment)
The accommodation bag 1 concerning 1st Embodiment of this invention is demonstrated using FIG. 1A-1C. 1A-1C are schematic views of a storage bag 1 according to the first embodiment. The storage bag 1 shown in FIGS. 1A to 1C is a sheet-like bag for storing the storage container 5. 1A and 1B show a state in which the storage container 5 is not accommodated (FIG. 1B is a developed view), and FIG. 1C shows a state in which the preservation container 5 is accommodated (corresponding to a section CC in FIG. 1A). . 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.

第１実施形態における収容袋１は、１枚のシート状部材を折り曲げることで形成されている。具体的には、図１Ｂに示されるシート状部材を、図１Ａに示すように折り曲げた後、互いに対向して配置されたシート状部材（第１シート状部材７と第２シート状部材８）における長手方向Ａ沿いの両端部を接合する。すなわち、第１、第２シート状部材７、８の短手方向Ｂにおける両端部を、第１、第２シート状部材７、８の長手方向Ａに沿って互いに接合する。図１Ａ、１Ｂでは、接合部６の境目を２点鎖線で表している。   The storage bag 1 in the first embodiment is formed by bending one sheet-like member. Specifically, after the sheet-like member shown in FIG. 1B is bent as shown in FIG. 1A, the sheet-like members (the first sheet-like member 7 and the second sheet-like member 8) arranged to face each other. Both end portions along the longitudinal direction A 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. In FIG. 1A and 1B, the boundary of the junction part 6 is represented with the dashed-two dotted line.

このように構成される収容袋１は、図１Ａ、１Ｃなどに示すように、開口部２と、底部３とを備えている。   The storage bag 1 configured in this way includes an opening 2 and a bottom 3 as shown in FIGS.

開口部２は、保存容器５を挿入するための開口を形成した第１、第２シート状部材７、８の長手方向Ａの一端に相当する。開口部２を形成するには、図１Ｂに示すように、シート状部材７、８の長手方向Ａにおける両端部２ａ、２ｂ（第１シート状部材７の一端２ｂ、第２シート状部材８の一端２ａ）を、図１Ａに示すように互いに対向するように重ね合わせることで形成する。開口部２の短手方向Ｂにおける両端部では、第１、第２シート状部材７、８が互いに接合されており、接合部６を形成している。このように開口部２の両端部に接合部６を設けて、開口部２の中央部には接合部６を設けないことで、開口部２の中央部を開放し、保存容器５を挿入するための開口を形成している。   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. In order to form the opening 2, as shown in FIG. 1B, both end portions 2 a and 2 b in the longitudinal direction A of the sheet-like members 7 and 8 (one end 2 b of the first sheet-like member 7 and the second sheet-like member 8 One end 2a) is formed by overlapping 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.

底部３は、収容袋１に挿入された保存容器５の底面を支持する部分である（図１Ｃ参照）。底部３は、図１Ａに示されるように、第１、第２シート状部材７、８の長手方向Ａの他端に相当する。底部３を形成するには、図１Ｂに示すように、シート状部材の短手方向Ｂに延びるライン３ａで折り曲げる（第１シート状部材７と第２シート状部材８を対向させるよう配置する）とともに、折り曲げた部分において、第１、第２シート状部材７、８の長手方向Ａ沿いの両端部を互いに接合して、接合部６を形成する。これにより、底部３が形成される。   The bottom part 3 is a part which supports the bottom face of the storage container 5 inserted in the storage bag 1 (see FIG. 1C). 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.

接合部６は、上述したように、第１、第２シート状部材７、８の互いに対向する側の面における長手方向Ａ沿いの端部（短手方向Ｂの端部）に設けられている。また、第１実施形態における接合部６は、図１Ｂに示すように、第１、第２シート状部材７、８の対向する側の面における長手方向Ａの全長にわたって設けられている。第１、第２シート状部材７、８の対向する側の面における長手方向Ａの全長にわたって接合部６が設けられることで、図１Ａに示される収容袋１においては、開口部２のみが開口し、その他の部分は接合部６によって接合され、閉塞した構造となる。   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.

接合部６は、第１、第２シート状部材７、８が互いに対向する内側（裏面側）にのみ設けられており、互いに対向せず外部に露出した外側（表面側）には設けられていない。   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 is exposed to the outside. Absent.

第１実施形態では、収容袋１を構成するシート状部材として、ＥＦＥＰ層とポリイミド層の２層による構造を採用している。ＥＦＥＰは融着性物質であり、ポリイミドは非融着性物質である。第１実施形態では、このような構造のシート状部材を、ポリイミド層が外側に露出し、ＥＦＥＰ層が内側に位置されるようにして配置している。すなわち、内側に配置したＥＦＥＰ層を融着して接合することで、シート状部材の接合部６を形成する一方、外側に配置したポリイミド層では融着・接合しないようにしている。当該構造は、特に極低温耐性の観点で優れており、例えば、液体窒素の沸点である-１９６℃という温度に対しても耐性を有する。   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. This structure is particularly excellent in terms of resistance to cryogenic temperatures, and has resistance to a temperature of −196 ° C., which is the boiling point of liquid nitrogen, for example.

ここで、図１Ａ、１Ｂに示すように、接合部６は、接合部６の幅を狭くして形成した幅狭部４を有している。具体的には、幅狭部４は、シート状部材における底部３よりも開口部２に近い箇所において、シート状部材の底部３を含む他の箇所よりも、短手方向Ｂ沿いの幅（短手方向幅）が狭くなった部分である。図１Ａに示すように、底部３を含むシート状部材の短手方向幅がＷ１であるのに対して、幅狭部４の短手方向幅は、Ｗ１よりも短く設定されている。特に、幅狭部４の最も短い短手方向幅をＷ２とする（Ｗ１＞Ｗ２）。   Here, as shown in FIGS. 1A and 1B, the joint portion 6 has a narrow portion 4 formed by narrowing the width of the joint portion 6. Specifically, the narrow portion 4 has a width (shorter) along the short direction B at a location closer to the opening 2 than the bottom portion 3 of the sheet-like member than other portions including the bottom portion 3 of the sheet-like member. This is the part where the width in the hand direction is narrow. As shown in FIG. 1A, the width in the short direction of the sheet-like member including the bottom 3 is W1, while the width in the short direction of the narrow portion 4 is set shorter than W1. In particular, the shortest lateral width of the narrow portion 4 is W2 (W1> W2).

第１実施形態では、図１Ａ、１Ｂに示すように、短手方向幅がＷ１である接合部６において、人の指にフィットしやすい円弧状の切欠きを設けることで、Ｗ１よりも短い幅を有する幅狭部４を画定・形成している。   In the first embodiment, as shown in FIGS. 1A and 1B, a width shorter than W <b> 1 is provided by providing an arc-shaped notch that easily fits a human finger at the joint 6 having a short-side width of W <b> 1. A narrow portion 4 having the following is defined and formed.

このような幅狭部４を形成するには、例えば、図１Ｂに示すように、矩形状のシート状部材７、８に円弧状の切欠き（切込み）を予め入れておいた後、切欠き部分を互いに重ね合わせるように配置して形成することができる。あるいは、矩形上のシート状部材７、８を互いに重ね合わせた後にシート状部材７、８に円弧状の切欠きを入れることで、同様に形成することもできる。   In order to form such a narrow portion 4, for example, as shown in FIG. 1B, arc-shaped cutouts (cuts) are made in advance in rectangular sheet-like members 7 and 8, and then cutouts are made. The portions can be formed so as to overlap each other. Alternatively, the rectangular sheet-like members 7 and 8 can be formed in the same manner by putting arc-shaped cutouts in the sheet-like members 7 and 8 after overlapping the sheet-like members 7 and 8 on the rectangle.

幅狭部４を形成する切欠きは、図１Ａ、１Ｂに示すように、シート状部材７、８の端縁ライン９ａ、９ｂの内側に設けた切欠きである。ここでの端縁ライン９ａ、９ｂとは、シート状部材７、８における短手方向Ｂの端縁が直線状に延びて形成するラインのことである。   As shown in FIGS. 1A and 1B, the notches forming the narrow portion 4 are notches provided inside the edge lines 9 a and 9 b of the sheet-like members 7 and 8. The edge lines 9a and 9b here are lines formed by extending the edge in the short direction B of the sheet-like members 7 and 8 linearly.

上述した幅狭部４は、後述するように、保存容器５を収容袋１に挿入する際に、保存容器５の挿入操作を容易なものとするように機能する部分である。第１実施形態では、保存容器５の挿入後に、幅狭部４よりも下方の位置で収容袋１を封止（シール）することができるように、幅狭部４の位置を底部３から所定距離離れた位置（少なくとも保存容器５の高さよりも所定距離分離れた位置）に設定している。第１実施形態における幅狭部４の位置（シート状部材の長手方向Ａにおける位置）は、シート状部材７、８における底部３よりも開口部２に近い箇所、すなわち、シート状部材７、８の長手方向Ａの中心位置よりも開口部２側の箇所に設定している。   As described later, the narrow portion 4 described above is a portion that functions to facilitate the insertion operation of the storage container 5 when the storage container 5 is inserted into the storage bag 1. In the first embodiment, after the storage container 5 is inserted, the position of the narrow portion 4 is predetermined from the bottom portion 3 so that the containing bag 1 can be sealed (sealed) at a position below the narrow portion 4. The position is set at a position separated by a distance (at least a position separated by a predetermined distance from the height of the storage container 5). The position of the narrow portion 4 (position in the longitudinal direction A of the sheet-like member) in the first embodiment is a location closer to the opening 2 than the bottom portion 3 in the sheet-like members 7 and 8, that is, the sheet-like members 7 and 8. Is set at a position closer to the opening 2 than the center position in the longitudinal direction A.

また、接合部６は後述するように、保存容器５を収容袋１に挿入し、収容袋１をシールした後における収容袋１のシール性を確保する部分である。よって、接合部６による収容袋１のシール性を向上させるためにも、接合部６の短手方向幅Ｗ１を所定長さ以上確保することが好ましい（例えば４ｍｍ）。一方で、接合部６のうちの幅狭部４は、収容袋１のシール後には保存容器５を密封・収容する区画より開口部２に近い箇所にあって、収容袋１のシール性には大きく寄与しない部分である。よって、幅狭部４の短手方向幅Ｗ２は、収容袋１を収容しない状態においてシート状部材７、８を互いに接合できる程度の長さであればよい（例えば１ｍｍ−１．５ｍｍ）。ただし、幅狭部４の短手方向幅Ｗ２は、このような長さに限らず、接合部６の短手方向幅Ｗ１よりも短ければよい。   Moreover, the junction part 6 is a part which ensures the sealing performance of the storage bag 1 after inserting the storage container 5 in the storage bag 1 and sealing the storage bag 1 so that it may mention later. Therefore, in order to improve the sealing performance of the storage bag 1 by the joint portion 6, it is preferable to secure the width W1 in the short direction of the joint portion 6 to a predetermined length or more (for example, 4 mm). On the other hand, the narrow portion 4 of the joint portion 6 is located closer to the opening 2 than the section for sealing and housing the storage container 5 after sealing the storage bag 1, This is a part that does not contribute greatly. Therefore, the width W2 in the short direction of the narrow portion 4 may be a length that allows the sheet-like members 7 and 8 to be joined to each other in a state where the accommodation bag 1 is not accommodated (for example, 1 mm to 1.5 mm). However, the width W2 in the short direction of the narrow portion 4 is not limited to such a length, and may be shorter than the width W1 in the short direction of the joint portion 6.

このような構成において、収容袋１内に大略円柱形の保存容器５を収容するときの作用および効果について、図１Ａ、１Ｃ等を用いて説明する。   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. 1A, 1C and the like.

保存容器５を収容袋１内に挿入する際には、まず、保存容器５の下部（底部）から、開口部２を通して収容袋１内に挿入する。このとき、例えば、幅狭部４にフィットするように指で幅狭部４を挟み、収容袋１を挟んだ状態にて幅方向に収容袋１を押すことにより、開口部２をシート状部材７、８の平面に対して垂直な方向へ広げることができる。   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. At this time, for example, by sandwiching the narrow portion 4 with a finger so as to fit the narrow portion 4 and pressing the storage bag 1 in the width direction with the storage bag 1 being sandwiched, the opening 2 is formed into a sheet-like member. It can be expanded in a direction perpendicular to the planes 7 and 8.

具体的には、幅狭部４以外の部分では、接合部６の短手方向幅が長いため、接合部６を両端部から指で挟んだ場合、接合部６自体が折れ曲がりやすくなってしまう。これに対して、幅狭部４では、接合部６の短手方向幅が短いため、両端部を指で挟んだ際に、接合部６自体が折れ曲がりにくくなっている。これにより、短手方向幅が短い幅狭部４では、他の接合部６の部分と比較すると相対的に、接合部６を挟む指の力が、シート状部材７、８の中心方向に働きやすくなる。このような幅狭部４による作用により、開口部２をシート状部材７、８の平面に対して垂直な方向へ変形させやすくすることができる。   Specifically, in the portion other than the narrow portion 4, the width in the short direction of the joint portion 6 is long. Therefore, when the joint portion 6 is sandwiched between fingers from both ends, the joint portion 6 itself is easily bent. On the other hand, in the narrow portion 4, since the width in the short direction of the joint portion 6 is short, the joint portion 6 itself is not easily bent when both ends are sandwiched between fingers. Thereby, in the narrow portion 4 having a short width in the short direction, the force of the fingers sandwiching the joint portion 6 works in the center direction of the sheet-like members 7 and 8 in comparison with the other joint portion 6 portions. It becomes easy. Due to the action of the narrow portion 4, the opening 2 can be easily deformed in a direction perpendicular to the plane of the sheet-like members 7 and 8.

また、幅狭部４を指で挟んで開口部２を広げたときには、開口部２だけでなくその下方に位置する幅狭部４周辺のシート状部材７、８も同じ方向に広がることとなる。これにより、保存容器５を開口部２の入口まで到達させた後も、保存容器５を開口部２より下方に向かって容易に押し込んで挿入することができる。   Further, when the opening 2 is widened with the narrow portion 4 sandwiched between fingers, not only the opening 2 but also the sheet-like members 7 and 8 around the narrow portion 4 positioned below the same spread in the same direction. . Thereby, even after the storage container 5 reaches the entrance of the opening 2, the storage container 5 can be easily pushed and inserted downward from the opening 2.

このように、接合部６の幅を狭くした幅狭部４を利用することで、保存容器５を収容袋１に容易に挿入することができる。   In this way, the storage container 5 can be easily inserted into the storage bag 1 by using the narrow portion 4 in which the width of the joint portion 6 is narrowed.

さらに、第１実施形態では、幅狭部４を画定する切欠きの形状を、人の指にフィットしやすい円弧形状としているため、幅狭部４を指で挟んだときにシート状部材７、８に対してより力をかけやすくなる。これにより、開口部２をシート状部材７、８の平面に対して垂直な方向へさらに広げやすくなっている。このように、幅狭部４の形状を円弧状とすることにより、保存容器５を収容袋１内に挿入する際により容易に挿入することができる。   Furthermore, in 1st Embodiment, since the shape of the notch which demarcates the narrow part 4 is made into the circular arc shape which fits a human finger easily, when pinching the narrow part 4 with a finger, the sheet-like member 7, Easier to apply power to 8 As a result, the opening 2 can be further easily expanded in a direction perpendicular to the plane of the sheet-like members 7 and 8. Thus, by making the shape of the narrow part 4 into an arc shape, the storage container 5 can be more easily inserted into the containing bag 1.

その後、保存容器５を収容袋１の長手方向Ａに沿って押し込むことで、保存容器５の下部を、収容袋１の底部３に到達させる。これにより、保存容器５は、開口部２と底部３の間で保持されて、開口部２と底部３の間には、保存容器５を収容するための収容空間が形成される。このような状態にて、収容袋１内に保存容器５が収容される。   Thereafter, the storage container 5 is pushed in along the longitudinal direction A of the storage bag 1 so that the lower part of the storage container 5 reaches the bottom 3 of the storage bag 1. As a result, the storage container 5 is held between the opening 2 and the bottom 3, and a storage space for storing the storage container 5 is formed between the opening 2 and the bottom 3. In such a state, the storage container 5 is accommodated in the accommodation bag 1.

保存容器５の収容後、シート状部材７、８における保存容器５の上面に対応する位置から開口部２までの位置にて封止（シール）を行うことで、収容袋１内をシールすることができる。すなわち、保存容器５を収容袋１内に密封・シールした状態で保管することができる。なお、第１実施形態では、幅狭部４の位置を保存容器５の高さよりも所定距離分離れた位置に設定しているため、保存容器５の挿入後、幅狭部４の下端よりも下方にて確実にシールを行うことができる。このように、幅狭部４の下端までの位置でシールを行うことで、シールに用いられる接合部６の短手方向幅Ｗ１を確保することができるため、所望のシール性を確保することができる。   After the storage container 5 is stored, the inside of the storage bag 1 is sealed by sealing (sealing) at a position from the position corresponding to the upper surface of the storage container 5 in the sheet-like members 7 and 8 to the opening 2. Can do. That is, the storage container 5 can be stored in a sealed and sealed state in the storage bag 1. In the first embodiment, the position of the narrow portion 4 is set to a position separated by a predetermined distance from the height of the storage container 5, so that after the storage container 5 is inserted, the position is lower than the lower end of the narrow portion 4. Sealing can be surely performed at the bottom. In this way, by performing sealing at a position up to the lower end of the narrow portion 4, the width W1 in the short direction of the joint portion 6 used for sealing can be ensured, so that a desired sealing property can be ensured. it can.

上述したように、第１実施形態にかかる収容袋１によれば、シート状部材７、８を接合する接合部６は、シート状部材７、８における底部３よりも開口部２に近い箇所に、幅が狭くなった幅狭部４を有する。これにより、収容袋１のユーザが指で幅狭部４を挟んで短手方向に押すことにより、開口部２をシート状部材７、８の平面に対して垂直に広がる方向へ変形させやすくなっている。このように開口部２を開きやすくした状態にて保存容器５を収容袋１内に挿入することで、保存容器５を容易に開口部２から挿入することができ、保存容器５の挿入操作をより容易なものとすることができる。また、開口部２が広がるだけでなく、幅狭部４周辺のシート状部材７、８も開口部２と同様に広がるため、収容袋１の底部３まで到達させる際の保存容器５の挿入操作をさらに容易なものとすることができる。   As described above, according to the storage bag 1 according to the first embodiment, the joining portion 6 that joins the sheet-like members 7 and 8 is closer to the opening 2 than the bottom portion 3 of the sheet-like members 7 and 8. The narrow portion 4 has a narrow width. Thereby, when the user of the storage bag 1 pushes the narrow part 4 with a finger in the short direction, the opening part 2 is easily deformed in a direction extending perpendicularly to the plane of the sheet-like members 7 and 8. ing. Thus, the storage container 5 can be easily inserted from the opening 2 by inserting the storage container 5 into the containing bag 1 in a state in which the opening 2 is easily opened. It can be made easier. Moreover, not only the opening 2 is widened, but also the sheet-like members 7 and 8 around the narrow portion 4 are widened in the same manner as the opening 2, so that the storage container 5 is inserted when reaching the bottom 3 of the containing bag 1. Can be made easier.

また、第１実施形態の収容袋１によれば、幅狭部４は、シート状部材７、８の長手方向Ａ沿いの両端部におけるそれぞれの接合部６に設けた切欠きによって画定される。これにより、幅狭部４を簡易に作成することができる。   Moreover, according to the storage bag 1 of 1st Embodiment, the narrow part 4 is demarcated by the notch provided in each junction part 6 in the both ends along the longitudinal direction A of the sheet-like members 7 and 8. FIG. Thereby, the narrow part 4 can be created easily.

さらに、第１実施形態の収容袋１によれば、幅狭部４の切欠きは、円弧形状を有する。これにより、ユーザの指が幅狭部４にフィットしやすくなるため、幅狭部４を幅方向に押すときに、開口部２を広げる効果を向上させることができ、保存容器５の挿入操作をさらに容易なものとすることができる。なお、切欠きの円弧における弦（接合部６の両端ライン上に一致）の長さを例えば、１５ｍｍ−１７ｍｍ程度（円弧の半径は１０ｍｍ程度）としてもよく、このような長さであれば、幅狭部４に指をフィットさせるという点で特に好ましい。   Furthermore, according to the accommodation bag 1 of 1st Embodiment, the notch of the narrow part 4 has circular arc shape. Thereby, since a user's finger becomes easy to fit in the narrow part 4, when pushing the narrow part 4 to the width direction, the effect which expands the opening part 2 can be improved, and insertion operation of the storage container 5 can be performed. It can be made even easier. Note that the length of the chord in the arc of the notch (which coincides with the both end lines of the joint 6) may be, for example, about 15 mm to 17 mm (the radius of the arc is about 10 mm). This is particularly preferable in terms of fitting a finger to the narrow portion 4.

また、第１実施形態の収容袋１によれば、第１、第２シート状部材７、８の接合部６は、第１、第２シート状部材７、８の面のうち、互いに対向する側の面における長手方向Ａの全長にわたって設けられる。これにより、収容袋１の密封性・シール性を向上させることができる。   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.

また、第１実施形態の収容袋１によれば、シート状部材７、８は、ＥＦＥＰ層とポリイミド層の２層構造であり、ポリイミド層を外側に露出させ、ＥＦＥＰ層を内側にて融着して接合するように配置されている。このようなＥＦＥＰ層とポリイミド層の２層構造は、極低温耐性に優れているため、特に冷凍保存用や冷蔵保存用の保存容器５を収容する際に、保存容器５およびその内容物をより適切に保護することができる。   Further, according to the storage bag 1 of the first embodiment, the sheet-like members 7 and 8 have 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. And are arranged to be joined. 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.

以上、第１実施形態の収容袋１について説明したが、幅狭部４を設ける以外に、その他の、開口部２を広げやすくする工夫を行ってもよい。例えば、図１Ａに示される状態の収容袋１において、開口部２に治具などを挿入して、開口部２を広がる方向に押圧することで開口部２を開かせる癖付けを行ってもよい。保存容器５の挿入前にこのような癖付けを施すことで、保存容器５を開口部２へさらに容易に挿入することができる。   As mentioned above, although the storage bag 1 of 1st Embodiment was demonstrated, you may perform the device which makes the opening part 2 easy to expand other than providing the narrow part 4. FIG. For example, in the housing bag 1 in the state shown in FIG. 1A, a jig or the like may be inserted into the opening 2 and brazing may be performed to open the opening 2 by pressing the opening 2 in the expanding direction. . By applying such brazing before the storage container 5 is inserted, the storage container 5 can be more easily inserted into the opening 2.

次に、第１実施形態の変形例１−５について、図２−５、６Ａ、６Ｂを用いて説明する。変形例１−４では、第１実施形態と比較して幅狭部４の形状が異なり、変形例５では、開口部２近傍のシート状部材の長さが異なっている。これら以外の構成については第１実施形態と共通するため、その説明を省略する。   Next, Modification 1-5 of the first embodiment will be described with reference to FIGS. 2-5, 6A, and 6B. In Modification 1-4, the shape of the narrow portion 4 is different from that in the first embodiment, and in Modification 5, the length of the sheet-like member near the opening 2 is different. Since the configuration other than these is common to the first embodiment, the description thereof is omitted.

（変形例１）
図２は、変形例１にかかる収容袋１１の斜視図を示す。図２に示すように、変形例１にかかる収容袋１１の幅狭部１４は、第１実施形態における幅狭部４よりも大きな円弧形状の切欠きによって画定・形成されている。具体的には、シート状部材７、８における底部３よりも開口部２に近い箇所において、実施形態１よりも大きな円弧状の切欠きを接合部６に設けることで、幅狭部１４を形成している。 (Modification 1)
FIG. 2 is a perspective view of the storage bag 11 according to the first modification. As shown in FIG. 2, the narrow portion 14 of the storage bag 11 according to Modification 1 is defined and formed by a circular arc-shaped notch that is larger than the narrow portion 4 in the first embodiment. Specifically, the narrow portion 14 is formed by providing the joint portion 6 with a circular arc-shaped notch larger than that of the first embodiment at a location closer to the opening portion 2 than the bottom portion 3 in the sheet-like members 7 and 8. doing.

このような形状の幅狭部１４であっても、第１実施形態と同様に、ユーザが幅狭部１４を指で挟んで幅方向に押すことにより、開口部２をシート状部材７、８の平面に対して垂直に開く方向へ変形させやすくなるため、保存容器５の挿入操作を容易に行うことができる。   Even in the narrow portion 14 having such a shape, as in the first embodiment, when the user presses the narrow portion 14 with a finger in the width direction, the opening 2 is formed into the sheet-like members 7 and 8. Therefore, the storage container 5 can be easily inserted.

（変形例２）
図３は、変形例２にかかる収容袋２１の斜視図を示す。図３に示すように、変形例２にかかる収容袋２１の幅狭部２４は、第１実施形態の幅狭部４と異なり、三角形状の切欠きにより画定・形成されている。具体的には、シート状部材７、８の平面に対して垂直な方向から見て、三角形状の切欠きを接合部６に設けることにより、幅狭部２４を形成している。 (Modification 2)
FIG. 3 is a perspective view of the accommodation bag 21 according to the second modification. As shown in FIG. 3, the narrow portion 24 of the storage bag 21 according to Modification 2 is defined and formed by a triangular notch, unlike the narrow portion 4 of the first embodiment. Specifically, the narrow portion 24 is formed by providing a triangular notch in the joint portion 6 when viewed from a direction perpendicular to the plane of the sheet-like members 7 and 8.

このような形状の幅狭部２４であっても、第１実施形態と同様に、ユーザが幅狭部２４を指で挟んで幅方向に押すことにより、開口部２をシート状部材７、８の平面に対して垂直に開く方向へ変形させやすくなる。具体的には、三角形状の切欠きによって、幅狭部２４に傾斜ライン２４ａが形成されているため、この傾斜ライン２４ａと指が接触することで、傾斜ライン２４ａのない形状と比較して指との接触点を増やしながらの接触が可能となる。このようにして、開口部２を変形させやすくすることができ、第１実施形態と同様に、保存容器５の挿入操作を容易に行うことができる。   Even in the narrow portion 24 having such a shape, as in the first embodiment, when the user presses the narrow portion 24 with a finger in the width direction, the opening 2 is formed into the sheet-like members 7 and 8. It becomes easy to be deformed in the direction of opening perpendicular to the plane. Specifically, since the inclined line 24a is formed in the narrow portion 24 by the triangular notch, the finger comes into contact with the inclined line 24a in comparison with the shape without the inclined line 24a. It is possible to make contact while increasing the number of contact points. In this way, the opening 2 can be easily deformed, and the storage container 5 can be easily inserted as in the first embodiment.

（変形例３）
図４は、変形例３にかかる収容袋３１の斜視図を示す。図４に示すように、変形例３にかかる収容袋３１の幅狭部３４は、第１実施形態の幅狭部４と異なり、四角形状の切欠きにより画定・形成されている。具体的には、シート状部材７、８に対して垂直な方向から見て、四角形状の切欠きを接合部６に設けることにより、幅狭部３４を形成している。 (Modification 3)
FIG. 4 is a perspective view of the containing bag 31 according to the third modification. As shown in FIG. 4, the narrow portion 34 of the storage bag 31 according to Modification 3 is defined and formed by a rectangular notch, unlike the narrow portion 4 of the first embodiment. Specifically, the narrow portion 34 is formed by providing a rectangular notch in the joint portion 6 when viewed from a direction perpendicular to the sheet-like members 7 and 8.

このような形状の幅狭部３４であっても、第１実施形態と同様に、幅狭部３４を挟む力がシート状部材７、８の中央部に伝わりやすいため、開口部２をシート状部材７、８の平面に対して垂直に開く方向へ変形させやすくなっている。これにより、保存容器５の挿入操作を容易に行うことができる。   Even in the narrow portion 34 having such a shape, the force sandwiching the narrow portion 34 is easily transmitted to the central portions of the sheet-like members 7 and 8 as in the first embodiment. It is easy to deform in a direction that opens perpendicularly to the plane of the members 7 and 8. Thereby, insertion operation of the storage container 5 can be performed easily.

（変形例４）
図５は、変形例４にかかる収容袋４１の斜視図を示す。図５に示すように、変形例４にかかる収容袋４１の幅狭部４４は、変形例３にかかる幅狭部３４と同様に、四角形状の切欠きにより形成されている点は共通する一方、変形例３にかかる幅狭部３４と異なり、開口部２の端部まで切欠きが到達している。すなわち、収容袋４１は、シート状部材７、８全体として開口部２側が窄まった窄まり形状を有している。 (Modification 4)
FIG. 5 is a perspective view of a storage bag 41 according to the fourth modification. As shown in FIG. 5, the narrow portion 44 of the storage bag 41 according to the modified example 4 is similar to the narrow portion 34 according to the modified example 3 in that it is formed by a rectangular notch. Unlike the narrow portion 34 according to the modified example 3, the notch reaches the end of the opening 2. That is, the storage bag 41 has a narrowed shape in which the opening 2 side is narrowed as a whole of the sheet-like members 7 and 8.

このような形状の幅狭部４４であっても、第１実施形態と同様に、幅狭部４４を挟む力がシート状部材７、８の中央部に伝わりやすいため、開口部２をシート状部材７、８の平面に対して垂直に開く方向へ変形させやすくなっており、保存容器５の挿入操作を容易に行うことができる。   Even in the narrow portion 44 having such a shape, the force sandwiching the narrow portion 44 is easily transmitted to the central portions of the sheet-like members 7 and 8 as in the first embodiment. It is easy to deform in a direction that opens perpendicularly to the plane of the members 7 and 8, and the storage container 5 can be easily inserted.

（変形例５）
図６Ａ、６Ｂは、変形例５にかかる収容袋５１の斜視図および展開斜視図をそれぞれ示す。図６Ａ、６Ｂに示すように、変形例５にかかる収容袋５１は、第１実施形態と同じ寸法・位置の幅狭部４を有する一方で、開口部５２を形成する箇所において、対向するシート状部材５７、５８のそれぞれの長手方向長さが異なるように形成されている。具体的には、図６Ａの紙面奥側にあるシート状部材５８の長手方向長さは第１実施形態と同じに設定されるのに対して、紙面手前側のシート状部材５７の長手方向長さは第１実施形態よりも短く設定されている。さらに言い換えると、対向するシート状部材５７、５８のそれぞれの開口端縁５２ａ、５２ｂの長手方向位置が異なるように形成されている。 (Modification 5)
6A and 6B respectively show a perspective view and a developed perspective view of a storage bag 51 according to Modification 5. FIG. As shown in FIGS. 6A and 6B, the accommodation bag 51 according to the modified example 5 has the narrow portion 4 having the same size and position as in the first embodiment, while the opening sheet 52 is opposed to the sheet. The longitudinal members 57 and 58 are formed to have different lengths in the longitudinal direction. Specifically, the length in the longitudinal direction of the sheet-like member 58 on the back side in FIG. 6A is set to be the same as that in the first embodiment, whereas the length in the longitudinal direction of the sheet-like member 57 on the near side of the paper surface. The length is set shorter than that in the first embodiment. In other words, the opening end edges 52a and 52b of the opposing sheet-like members 57 and 58 are formed so that the longitudinal positions thereof are different.

このように、開口部５２において、対向するシート状部材５７、５８のそれぞれの開口端縁５２ａ、５２ｂの長手方向位置を異ならせることにより、開口部５２に段差を設けている。このような段差を設けることにより、保存容器５の挿入時に、保存容器５を開口部５２へより容易に挿入することができる。   As described above, the opening 52 is provided with a step by changing the longitudinal positions of the opening edges 52 a and 52 b of the sheet-like members 57 and 58 facing each other in the opening 52. By providing such a step, the storage container 5 can be more easily inserted into the opening 52 when the storage container 5 is inserted.

すなわち、変形例５の収容袋５１によれば、幅狭部４を用いて開口部５２を広げやすくするだけでなく、シート状部材５７、５８のそれぞれの開口端縁５２ａ、５２ｂの長手方向位置を異ならせることで、保存容器５をさらに容易に開口部５２へ挿入することができる。   That is, according to the storage bag 51 of the modified example 5, not only the opening portion 52 is easily widened using the narrow portion 4, but also the longitudinal positions of the opening edges 52a and 52b of the sheet-like members 57 and 58, respectively. Therefore, the storage container 5 can be inserted into the opening 52 more easily.

なお、本発明は上記実施形態に限定されるものではなく、その他種々の態様で実施できる。例えば、第１、第２実施形態では、シート状部材７、８がＥＦＥＰ層とポリイミド層の２層構造である場合について説明したが、シート状部材７、８の材質や積層数はこれに限らない。例えば、単層や３層以上の構造を採用してもよい。また、２層以上の多層構造の場合には、例えば、外側に露出する最外層と、内側に配置して接合を行う最内層の材料に関して、最外層の材料の融点が最内層の材料の融点よりも高くなるように、それぞれの層の材料を選択してもよい。このような融点の違いを利用した材料の選択（例えば、熱可塑性樹脂）により、第１、第２実施形態と同様の構造を、ＥＦＥＰやポリイミドに限らずに実現することができる。例えば、最外層の材料として、融点の高い物質であるポリアミド（融点は例えば２２５℃）を採用し、最内層の材料として融点の低い物質であるポリエチレン（融点は例えば１２０℃）を採用し、例えば１９０℃ほどの温度にて加熱することで、最内層であるポリエチレン層のみを融着させることができる。   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 members 7 and 8 have a two-layer structure of the EFEP layer and the polyimide layer has been described. However, the material and the number of stacked layers of the sheet-like members 7 and 8 are not limited thereto. Absent. 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 can be realized without being limited to EFEP or 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., only the innermost polyethylene layer can be fused.

また、前記では、保存容器５の形状として大略円柱形状を主に想定していたが、保存容器５の形状はこれに限らず例えば、大略四角柱形状などであってもよい。   In the above description, the shape of the storage container 5 is mainly assumed to be a substantially cylindrical shape. However, the shape of the storage container 5 is not limited to this, and may be, for example, a substantially rectangular column shape.

また、前記では、幅狭部４を形成する切欠きの形状が、円弧形状、三角形状、四角形状などである場合について説明したが、このような場合に限らず、幅の狭くなった幅狭部４を形成するものであれば他の形状であってもよい。また例えば、切欠きが円弧形状の場合には、円弧の曲率を適宜設定してもよく、三角形状や四角形状の場合には、各辺の傾斜角度を適宜設定してもよいことは明らかである。   In the above description, the case where the shape of the notch forming the narrow portion 4 is an arc shape, a triangular shape, a quadrangular shape, or the like has been described. However, the present invention is not limited to such a case, and the narrow width is reduced. Any other shape may be used as long as it forms part 4. In addition, for example, when the notch has an arc shape, the curvature of the arc may be set as appropriate, and when the cutout is a triangle or a quadrangle, the inclination angle of each side may be set as appropriate. is there.

また、前記では、シート状部材７、８における幅狭部４よりも下方が真っ直ぐな形状（ストレート形状）である場合について説明したが、このような場合に限らない。例えば、シート状部材７、８における幅狭部４よりも下方において、シート状部材７、８を部分的に折り返したり、あるいは、開口部２に近い幅狭部以外の幅狭部を設けるなど、その他の各種形状を採用してもよい。   Moreover, although the above demonstrated the case where the downward direction rather than the narrow part 4 in the sheet-like members 7 and 8 was a straight shape (straight shape), it is not restricted to such a case. For example, the sheet-like members 7 and 8 are partially folded back below the narrow portion 4 in the sheet-like members 7 and 8, or a narrow portion other than the narrow portion close to the opening 2 is provided. Various other shapes may be employed.

また、前記では、シート状部材７、８の端縁ライン９ａ、９ｂの内側に切欠きを設けることによって幅狭部４を画定・形成する場合について説明したが、このような場合に限らない。例えば、シート状部材７、８に切欠きを設けずに、接合部６をシート状部材７、８の端縁ライン９ａ、９ｂに全て沿うように形成しつつ、接合部６の幅を部分的に狭くすることで、幅狭部４を画定・形成するようにしてもよい。   In the above description, the case where the narrow portion 4 is defined and formed by providing notches inside the edge lines 9a and 9b of the sheet-like members 7 and 8 has been described. However, the present invention is not limited to such a case. For example, without forming notches in the sheet-like members 7, 8, the joint portion 6 is formed so as to all follow the edge lines 9 a, 9 b of the sheet-like members 7, 8, and the width of the joint portion 6 is partially The narrow portion 4 may be defined and formed by narrowing it to be narrow.

なお、上記様々な実施形態のうちの任意の実施形態を適宜組み合わせることにより、それぞれの有する効果を奏するようにすることができる。   It is to be noted that, by appropriately combining arbitrary embodiments of the various embodiments described above, the effects possessed by them can be produced.

本発明は、例えば生体性物質を冷蔵保存するための保存容器を収容する収容袋に適用することができる。   The present invention can be applied to a storage bag that stores a storage container for refrigerated storage of biological materials, for example.
