(Embodiment)
A storage bag 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2 are schematic views of a storage bag 1 according to the embodiment. The storage bag 1 shown in FIGS. 1 and 2 is a sheet-like bag for storing the storage container 5 and is used for various medical applications (including regenerative medical applications). FIG. 1 shows a state in which the storage container 5 is not accommodated, and FIG. 2 shows a state in which the storage container 5 is accommodated (corresponding to the CC cross section in FIG. 1). 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 embodiment is formed by bending one sheet-like member. Specifically, after a sheet-like member on a single rectangle is bent as shown in FIG. 1, sheet-like members (first sheet-like member 7 and second sheet-like member 8 arranged opposite to each other). The two end portions along the longitudinal direction A in FIG. 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. 1, 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 and a bottom 3 as shown in FIGS.

  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, both end portions 2 a and 2 b (one end 2 b of the first sheet-like member 7 and one end 2 a of the second sheet-like member 8) in the longitudinal direction A of the sheet-like members 7 and 8 are shown in FIG. As shown in FIG. 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 in the storage bag 1 (see FIG. 2). As shown in FIG. 1, 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 portion 3, it is bent along a line 3 a 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), and in the bent portion, Both end portions along the longitudinal direction A of the first and second sheet-like members 7 and 8 are joined together to form a joined portion 6. Thereby, the bottom part 3 is formed.

  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 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 in FIG. In the accommodation bag 1 shown in FIG. 1, 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 is exposed to the outside. Absent.

  In the embodiment, as the sheet-like member constituting the containing bag 1, a structure having two layers of an EFEP layer and a polyimide layer is adopted. EFEP is a fusible substance, and polyimide is a non-fusible substance. In the 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.

  Here, the sheet-like members 7 and 8 are provided with a plurality of notches 4a to 4d. Specifically, four V-shaped cutouts 4a to 4d are provided at the outer ends in the short direction B of the sheet-like members 7 and 8. These notches 4a to 4d are provided so that the storage container 5 can be easily removed from the storage bag 1 after the storage container 5 is stored, as will be described later.

  As shown in FIG. 1, the notches 4 a and 4 b are arranged to face each other along the short direction B of the sheet-like members 7 and 8. Similarly, the notches 4c and 4d are arranged so as to face each other along the short direction B of the sheet-like members 7 and 8. The notches 4a and 4c are provided at the joint 6 on one side (left side in FIG. 2) in the short direction B of the sheet-like members 7 and 8, and the notches 4b and 4d 8 is provided at the joint 6 on the other side (right side in FIG. 2) in the lateral direction B. The notches 4a and 4b are arranged on the side closer to the opening 2 than the notches 4c and 4d in the longitudinal direction A of the sheet-like members 7 and 8.

  Since these notches 4a-4d have a V-shape, after the storage container 5 as shown in FIG. 2 is accommodated, the user of the accommodation bag 1 does not use a tool such as scissors. -4d can be torn and opened from one of the storage bags 1.

  As will be described later, the joint portion 6 is a portion that ensures the sealing performance of the storage bag 1 after the storage container 5 is inserted into the storage bag 1 and the storage bag 1 is sealed. Therefore, in order to improve the sealing performance of the storage bag 1 by the joint portion 6, it is preferable to secure a predetermined length in the width direction W1 of the joint portion 6 (for example, 4 mm or more and 5 mm or less). On the other hand, in the part where the notch 4a-4d is formed in the joint portion 6, the width in the short direction is narrowed, so that the width W2 of the part becomes a predetermined length (for example, 2 mm or more and 3 mm). What is necessary is just to set the shape and length of the notch 4a-4d (for example, the width of 1 mm or more and 3 mm or less).

  In the first embodiment, the shape of the notches 4a to 4d in plan view is an equilateral triangle, and the width in the short direction is 1 mm or more and 3 mm or less. However, the shape and length are limited to this. Not.

  In such a configuration, an operation when the substantially cylindrical storage container 5 is stored in the storage bag 1 will be described with reference to FIGS.

  When the storage container 5 is inserted into the storage bag 1, first, the storage container 5 is inserted into the storage bag 1 from the lower part (bottom part) of the storage container 5 through the opening 2. Thereafter, the storage container 5 is pushed in until it reaches the bottom 3. The storage container 5 is sealed in the storage bag 1 by sealing the opening 2 side while the storage container 5 is pushed down to the bottom 3. In this way, the storage container 5 can be stored in the storage bag 1.

  The storage container 5 in the storage bag 1 is stored for a predetermined period, and then taken out from the storage bag 1 and used. At this time, the operator of the storage bag 1 pulls the storage bag 1 in the short direction B along one of the V-shaped cutouts 4a to 4d. Can be cut and opened. Thereby, the storage container 5 can be taken out from the storage bag 1.

  Thus, by providing the V-shaped notches 4a to 4d, the storage container 5 can be taken out from the storage bag 1 without using a tool such as scissors, and the operability of the storage bag 1 is improved. be able to. In particular, in the medical field, the storage bag 1 that stores the storage container 5 storing cells and the like is often handled in a clean room, and in principle, the use of tools such as scissors is prohibited. In such a case, since the storage bag 1 in the first embodiment can be opened and the storage container 5 can be taken out without using a tool such as scissors, the operation of the storage bag 1 is possible. And convenience can be further improved. When opening with scissors or the like, the glove worn by the operator may be accidentally scratched and may cause contamination. Such a risk can be avoided. Furthermore, especially in the field of regenerative medicine in the medical field, it is required to handle the containing bag 1 in a cleaner state. Therefore, when the storage bag 1 is used as a storage bag for regenerative medicine, the effect of improving operability and the effect of reducing contamination risk can be further exhibited.

  As described above, according to the storage bag 1 according to the embodiment, the storage bag 1 is for storing the storage container 5, and is along the longitudinal direction A in the sheet-like members 7, 8 arranged to face each other. Both ends are joined, and a V-shaped notch 4 a-4 d is provided at the outer end in the short direction B at the joint 6 that joins both ends of the sheet-like members 7, 8. Thereby, after the storage container 5 is stored, the operator can tear the storage bag 1 by hand along the notches 4a to 4d, thereby opening the storage bag 1 and taking out the storage container 5. Thus, since the storage container 5 can be taken out from the storage bag 1 without a tool such as scissors, the operability of the storage bag 1 can be improved. In particular, as the medical storage bag 1, the operability improvement effect can be further exhibited.

  Further, according to the storage bag 1 of the embodiment, a plurality of V-shaped cutouts 4 a-4 d are provided along the longitudinal direction A of the sheet-like members 7, 8. Thereby, after the storage container 5 is accommodated, the operator can select a notch used for opening from the plurality of notches 4a-4d. For this reason, the operativity and convenience of the storage bag 1 can be improved.

  Furthermore, according to the storage bag 1 of the embodiment, the V-shaped cutouts 4a to 4d are provided at the joints 6 on both sides of the sheet-like members 7 and 8 so as to face each other along the short direction B. ing. Thus, by arranging the notches 4a to 4d at symmetrical positions, for example, when the containing bag 1 is mass-produced, it can be efficiently produced.

  Furthermore, according to the storage bag 1 of the embodiment, the width in the short-side direction of the joint 6 in which the V-shaped notches 4a to 4d are formed is 2 mm or more and 3 mm or less. Thereby, the reliability of the sealing in the accommodation bag 1 by the junction part 6 is securable.

  Furthermore, according to the storage bag 1 of the embodiment, the lateral width of the V-shaped cutouts 4a-4d is 1 mm or more and 3 mm or less.

  Moreover, the storage bag 1 of the embodiment is a storage bag 1 for regenerative medicine. The regenerative medical use has particularly severe hygienic conditions, and the operator is required to handle the containing bag 1 using gloves or the like. Therefore, the operability improvement effect by the notches 4a-4d that can be opened without using a tool such as scissors can be further exhibited.

  In addition, this invention is not limited to the said embodiment, It can implement in another various aspect. For example, in the above-described embodiment, the case where the V-shaped notches 4a to 4d are provided has been described. However, the present invention is not limited to such a case. For example, instead of the V-shaped cutouts 4a to 4d, simple cuts such as cutting the sheet-like members 7 and 8 with scissors or the like may be provided. Even when such a cut is provided, the storage bag 1 can be opened without using a tool such as scissors, as in the case where the V-shaped cutouts 4a to 4d are provided. The operability can be improved.

  Moreover, although the above demonstrated the case where the notch 4a-4d whole was V-shaped, it was not restricted to such a case. Specifically, the cutouts 4a to 4d may have a V shape at least on the center side along the short direction B. That is, as long as it has a V shape on the center side, an arbitrary shape different from the V shape (for example, a linear shape extending in parallel with the short direction B) is added to the outside of the V shape. Also good. The accommodation bag 10 provided with the notch of such a shape is shown in FIG. FIG. 3 is an enlarged view of one notch 14 among the four notches provided in the storage bag 10. Since the other three notches have the same shape, illustration is omitted. As shown in FIG. 3, the notch 14 includes a V-shaped portion 15 and a straight portion 16. The V-shaped portion 15 is a portion having a V-shape provided on the center side in the lateral direction B. The straight line portion 16 is a portion connected to the outside of the V-shaped portion 15 so as to extend in parallel with the short direction B. Even with such a configuration, by having the V-shaped portion 15 on the inside, the containing bag 10 can be opened without using a tool such as scissors as in the case of the containing bag 1 of the above-described embodiment. The operability of the storage bag 10 can be improved. When the notch 14 has such a straight portion 16, it can be produced more efficiently when the accommodation bag 10 is produced. Specifically, when the storage bag 10 is produced, as shown in FIG. 4, the storage bag 10 is produced from a state in which the plurality of storage bags 10 a and 10 b are connected along the short direction B. In such a state, first, the adjacent portions of the two storage bags 10a and 10b are heat-sealed to form the joint portions 6a and 6b. Then, a notch is provided inside the joints 6a and 6b. This notch corresponds to the two notches 14 shown in FIG. 3 described above arranged in line symmetry (notches 14a and 14b). In this state, the accommodation bag 10a and the accommodation bag 10b can be divided into the accommodation bags 10a and 10b by cutting along the dividing line D that is the same direction as the longitudinal direction A. By such a method, the accommodation bags 10a and 10b having the notches 14a and 14b having the same shape as the notches 14 of FIG. 3 can be produced. This production method includes an operation of dividing the containing bags 10a and 10b along the dividing line D. This dividing line D may be displaced along the short direction B due to manufacturing errors. On the other hand, the notch 14 shown in FIG. 3 has a straight portion 16 extending parallel to the short direction B, and the dividing line D is defined at a position across the straight portion 16 as shown in FIG. ing. Since the straight line portion 16 is axisymmetric with respect to the dividing line D, even if the dividing line D is slightly displaced along the short direction B, the shapes of the notches 14a and 14b can be maintained to be substantially the same. it can. Thereby, compared with the case where it forms only by the V-shaped part 15 without providing the linear part 16, the shape of a notch can be stabilized and the accommodation bag 10 can be produced more efficiently.

  Moreover, although the above demonstrated the case where the part except the notch 4a-4d in the sheet-like members 7 and 8 was a straight shape (straight shape), it has not only such a case but various shapes. Also good.

  In the above description, 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. 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.

  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.

  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.

  The present invention can be applied to, for example, a medical storage bag that stores a storage container for refrigerated storage of biological substances.
