[Embodiment 1]
Below, one embodiment of an enclosure is described first, and then one embodiment of a method for manufacturing a package is described.

(Encapsulated container)
FIG. 1 is a schematic diagram of an enclosure 1 according to Embodiment 1 of the present disclosure. The enclosure 1 according to the present embodiment is a container that is hermetically sealed by welding the introduction flow path 2 that is a part of the enclosure, and the contents C are enclosed therein. The enclosure 1 includes an introduction channel 2 into which the contents are introduced, and an accommodating portion 3 that communicates with the introduction channel 2 and accommodates the contents C. Although details will be described later, in the sealed container 1 of the present embodiment, the introduction flow path 2 includes a sealing target position display unit 21 that displays a sealing target position for sealing the housing unit 3.

  The contents C accommodated in the accommodating portion 3 of the enclosure 1 are not particularly limited. For example, a chemical solution, cell suspension, extracellular fluid, infusion solution, or fluidity that requires aseptic handling is required. Examples thereof include foods.

  The material of the container 3 and the introduction flow path 2 is not particularly limited as long as it can seal the contents C. For example, polyethylene, polypropylene, which are materials excellent in low temperature durability that can be cryopreserved at low temperature, Resin materials such as ethylene vinyl acetate copolymer can be used. The accommodating portion 3 and the introduction channel 2 may be a resin bag in which the peripheral portions are joined by overlapping the above-described resin material films. The minimum use temperature of the accommodating part 3 and the introduction flow path 2 is about -196 degreeC, for example. The minimum use temperature is a lower limit temperature that does not cause problems such as breakage in normal use. That is, the enclosure 1 can be used as a cryopreservation container.

  In the example shown in FIG. 1, the enclosure 1 has a part of the housing part 3 protruding outward to form the introduction channel 2, and is opposite to the housing part 3 of the introduction channel 2 rather than the sealing target position display unit 21. Is connected to an introduction pipe 4 for introducing the contents C into the introduction flow path 2. The accommodating portion 3 has, for example, a rectangular shape, and has an upper edge portion 31a, a lower edge portion 31b, and a pair of side edge portions 31c as the peripheral edge portion 31 thereof.

  The introduction flow path 2 extends from the one side of the upper edge part 31a, the lower edge part 31b, and the pair of side edge parts 31c of the peripheral part 31 of the storage part 3 to the outside of the storage part 3 in a direction perpendicular to the one side. It is provided so as to protrude toward. The protruding direction of the introduction flow path 2 is not limited to the direction perpendicular to each side of the peripheral edge portion 31 of the accommodating portion 3, and each side may have a predetermined angle. The width of the introduction flow path 2 in the direction perpendicular to the protruding direction of the introduction flow path 2 is smaller than the length of each side of the peripheral edge portion 31. The proximal end of the introduction flow path 2 communicates with the accommodating portion 3, and the distal end of the introduction flow path 2 is connected to the introduction pipe 4.

  For example, a port 5 for connecting the introduction pipe 4 is provided at the tip of the introduction flow path 2. The port 5 functions as an introduction port for introducing the contents C from the introduction pipe 4 to the introduction flow path 2. When the port 5 has the conduit 5a introduced into the introduction channel 2, the length of the conduit 5a is set on the side of the accommodating part 3 of the conduit 5a from the viewpoint of smoothly welding the introduction channel 2. It is preferable that the end portion has a length that does not reach the sealing target position display portion 21. The introduction flow path 2 has the sealing target position display part 21 which displays the sealing target position for sealing the accommodating part 3 as mentioned above.

  The sealing target position display part 21 is a position where the sealing part S (see FIG. 3) for sealing the accommodating part 3 by welding is to be formed after filling the contents C in the accommodating part 3. There is no particular limitation as long as the position can be displayed. For example, the sealing target position display unit 21 forms an unevenness or a flat surface on the outer surface of the introduction flow path 2, displays a pattern, a line, a character, a color, or a combination thereof by printing or the like. A part of 2 can be colored, opaque or transparent so that it can be distinguished from other parts.

  When manufacturing the package P (refer FIG. 3) which enclosed the content C in the accommodating part 3 of the enclosure 1, the weight error of the content C is about several to 1% of the weight of the content C. In some cases. In this case, for example, when there is a large variation in the position of the sealing portion S that is formed in the introduction flow channel 2 by welding and seals the housing portion 3, the cutting position of the introduction flow channel 2 according to the position of the sealing portion S Variation occurs. Therefore, the variation of the weight of the enclosing container 1 becomes large, the error of the weight of the contents C cannot be measured accurately, and there is a possibility that a problem in management of the contents C may occur.

  The sealing target position display unit 21 can be formed, for example, at a position where the management problem of the contents C as described above can be solved. Specifically, in the sealed container 1 according to the present embodiment, the weight of the introduction flow path 2 from the sealing target position display unit 21 to the proximal end of the introduction flow path 2 connected to the storage unit 3 is, for example, the contents It is 1% or less of the target weight of C. That is, the weight of the portion from the base end of the introduction channel 2 to the boundary of the sealing target position display unit 21 on the tip side in the protruding direction opposite to the base end of the introduction channel 2 is filled in the storage unit 3. The width of the introduction flow path 2 and the dimensions of the sealing target position display unit 21 can be determined so as to be smaller than the allowable error in the weight of the content C to be processed. In the case where the sealing target position display unit 21 is displayed by characters or marks, the print or character end on the distal end side of the introduction flow path 2 is used as the sealing target position display section 21 on the distal end side of the introduction flow path 2. Can be the boundary.

  The boundary of the sealing target position display unit 21 on the proximal end side of the introduction flow path 2 is, for example, coincident with the base end of the introduction flow path 2 or the periphery of the storage unit 3 when the sealing target position display unit 21 is welded. A gap that can prevent interference with the portion 31 can be provided between the base end of the introduction flow path 2 and the gap. Note that, in the projecting direction of the introduction flow path 2, the size of the sealing target position display unit 21 from the boundary on the distal end side to the boundary on the proximal end side of the introduction flow path 2 is sealed by sealing the introduction flow path 2. Can be made equal to or larger than the possible dimensions.

  One end of the introduction pipe 4 is connected to the supply source of the contents C such as a supply container (not shown), the other end is connected to the introduction flow path 2, and the contents C are transferred from the supply source to the introduction flow path 2. Forming a channel for the purpose. The introduction pipe 4 is connected to the introduction flow path 2 by inserting, for example, the port 5 at the tip of the introduction flow path 2 into the end portion of the introduction pipe 4. The end portion of the introduction pipe 4 is fixed to the port 5 at the tip of the introduction flow path 2 by, for example, a mechanical joint portion such as a binding band or a chemical joint portion by solvent adhesion using an adhesive.

  The material of the introduction tube 4 is preferably a resin material having thermoplasticity capable of aseptic welding and bonding, but is not particularly limited. As the material of the introduction tube 4, for example, a resin material such as polyvinyl chloride (PVC), ethylene / vinyl acetate copolymer resin (EVA), polyolefin, C-flex (registered trademark), or the like can be used. The minimum use temperature of the PVC introduction pipe 4 is, for example, about −25 ° C., and the minimum use temperature of the EVA introduction pipe 4 is, for example, about −70 ° C. That is, in the sealed container 1 according to an embodiment of the present disclosure, the minimum use temperature of the introduction pipe 4 is higher than the minimum use temperature of the housing portion 3 including the introduction flow path 2.

  In addition, when the minimum use temperature of the introduction pipe 4 is higher than the minimum use temperature of the storage unit 3 and the sealed container 1 is used as a cryopreservation container, the contents C are placed in the storage unit 3 from the viewpoint of improving safety. After filling and sealing, it is necessary to remove the introduction tube 4 before freezing the enclosure 1.

(Manufacturing method of packaging)
Next, an embodiment of a method for manufacturing a package using the sealed container 1 according to the first embodiment will be described. FIG. 2 is a flowchart showing steps included in the package manufacturing method S100 according to the first embodiment of the present disclosure. FIG. 3 is a schematic diagram illustrating an example of a package P manufactured by the package manufacturing method S100 illustrated in FIG.

  The package manufacturing method S100 according to the present embodiment is a method for manufacturing a package P in which the contents C are introduced into the sealed container 1 and sealed. In the package manufacturing method S100 of the present embodiment, the introduction flow path 2 is welded in the accommodating step S2 in which the contents C are accommodated in the accommodating portion 3 through the introduction flow path 2 and the sealing target position display portion 21. It has sealing process S3 which seals the accommodating part 3, and cutting process S4 which cut | disconnects the introduction flow path 2. FIG. In addition, you may have connection process S1 which connects the introduction pipe | tube 4 to the introduction flow path 2 which is a part of the accommodating part 3 before accommodation process S2. Moreover, you may have the measurement process S5 which measures the package P obtained after cutting process S4.

(Connection process)
The connecting step S <b> 1 is a step of connecting the introduction pipe 4 to the housing part 3. In the manufacturing method S100 of the package of this embodiment, in the connection step S1, the introduction pipe 4 is connected to the tip of the introduction flow path 2 formed by projecting a part of the accommodating portion 3. The introduction pipe 4 can be connected to the port 5 provided at the tip of the introduction flow path 2 by a chemical method such as solvent bonding or a mechanical method such as a fastening band.

  In the manufacturing method of the present embodiment, as described above, the introduction pipe 4 is made of a material having a low freezing resistance that is not premised on cryopreservation, and is used as the material for the accommodation channel 3 and the introduction channel 2 communicating with the accommodation unit. In addition, a material having high freezing resistance that can be cryopreserved can be used. In addition, for example, when the housing part 3, the introduction flow path 2, and the introduction pipe 4 are integrally formed of the same material or different materials, or when the introduction pipe 4 is connected to the housing part 3 in advance, a connecting step S1 can be omitted.

(Containment process)
The housing step S <b> 2 is a step of housing the content C in the housing portion 3 through the introduction flow path 2. In the package manufacturing method S100 of the present embodiment, the contents C are introduced into the accommodating portion 3 through the introduction channel 2 and the introduction pipe 4 connected to the introduction channel 2 in the accommodating step S2. . Examples of the contents C to be stored in the storage unit 3 include, as described above, for example, chemicals, cell suspensions, extracellular fluids, infusions, or fluid foods that require aseptic handling. be able to.

(Sealing process)
The sealing step S <b> 3 is a step in which the introduction channel 2 is welded in the sealing target position display unit 21 to seal the housing unit 3. More specifically, for example, a desktop type welding machine or the like generally used in aseptic welding in a closed system is used, and the introduction flow path 2 is sandwiched in the sealing target position display unit 21, as shown in FIG. As shown, a sealing portion S that seals the introduction flow path 2 is formed by thermal welding. In the sealing step S <b> 3, the sealing portion S is between the boundary of the sealing target position display portion 21 on the distal end side of the introduction flow path 2 and the boundary of the sealing target position display portion 21 on the proximal end side of the introduction flow path 2. To form. In other words, the sealing part S can be formed on the sealing target position display part 21.

(Cutting process)
Cutting process S4 is a process of cutting introduction channel 2 after sealing process S3. The cutting position of the introduction flow path 2 in the cutting step S4 can be, for example, the boundary of the sealing target position display unit 21 on the distal end side of the introduction flow path 2. Further, the cutting position of the introduction flow path 2 is introduced from the front end side of the introduction flow path 2 with respect to the sealing section S, that is, the introduction section 3 from the viewpoint of preventing the sealing performance of the sealing section S from being deteriorated. It is preferable that the end edge is on the opposite side of the base end of the flow path 2 or the front end side of the introduction flow path 2 is more than the end edge. Note that the cutting position of the introduction channel 2 may be on the sealing portion S as long as the sealing property of the sealing portion S can be secured. Thus, the package P shown in FIG. 3 is obtained. That is, in the package manufacturing method S100 according to the present embodiment, the package P sealed by introducing the contents C into the container 3 of the enclosure 1 described above is obtained.

(Weighing process)
The measuring step S5 is a step of measuring the weight of the package P obtained in the cutting step S4. In the weighing step S5, a package P having a measured error of the content C within an error range of, for example, several percent to about 1% of a specified weight is determined to be an acceptable product, and has a further error. The object P can be determined as a rejected product.

  Hereinafter, the operation of the enclosure 1 and the manufacturing method S100 of the package according to the present embodiment will be described.

  The enclosure 1 of the present embodiment is an enclosure 1 that is partially welded and the contents C are enclosed as described above. The enclosure 1 includes an introduction channel 2 into which the content C is introduced, and a storage unit 3 that communicates with the introduction channel 2 and stores the content C. The introduction flow path 2 has a sealing target position display unit 21 that displays a sealing target position in order to seal the container 3.

  With such a configuration, in the sealing step S <b> 3, the introduction channel 2 can be welded by the sealing target position display unit 21 that displays the sealing target position of the introduction channel 2, and the accommodating unit 3 can be sealed. That is, the introduction flow path 2 can be welded at a fixed position to seal the accommodating portion 3, and not only can the welding be facilitated, but also management problems after the contents C are sealed can be solved. Can do.

  More specifically, for example, the variation of the weight of the enclosure 1 in the package P can be achieved by keeping the position of the sealing portion formed in the introduction flow path 2 by welding and sealing the accommodating portion 3 within a predetermined range. Can be reduced. Accordingly, the weight of the contents C can be accurately measured by subtracting the weight of the container 3 of the enclosure 1 and the remainder of the introduction channel 2 from the weight of the package P, and the weight of the contents C can be accurately measured. Can solve management problems. In addition, the weight of the accommodating part 3 of the enclosure 1 and the remaining part of the introduction channel 2 is obtained by, for example, subtracting the weight of a part of the introduction channel 2 cut from the weight of the enclosure 1 before the introduction channel 2 is cut. Can be measured.

  In addition, as described above, in the enclosure 1 of the present embodiment, a part of the accommodating portion 3 protrudes outward to form the introduction channel 2, and the sealing target position display unit 21 of the introduction channel 2 is more than the sealing target position display unit 21. An introduction pipe 4 for introducing the contents C into the introduction flow path 2 is connected to the distal end side. Therefore, the accommodating part 3 can be sealed in the sealing target position display part 21 of the introduction flow path 2, and then the introduction pipe 4 and the joint between the introduction flow path 2 and the introduction pipe 4 can be excised. Thereby, for example, the introduction pipe 4 having a low freezing resistance and the introduction flow path 2 communicating with the containing part 3 having a high freezing resistance are joined together by solvent adhesion, and the contents C are accommodated in the containing part 3 and stored in a frozen state after being sealed. Even in such a case, the concern about the residual solvent and the concern about the durability of the introduction pipe 4 and its connecting portion can be eliminated. Moreover, even when connecting the introduction pipe 4 and the accommodating portion 3 by a mechanical connection means such as a binding band, the mechanical connection means having a bonding strength weaker than solvent adhesion and fearing a decrease in reliability is removed, Such concerns can be dispelled.

  That is, even if the minimum use temperature of the introduction pipe 4 is higher than the minimum use temperature of the housing part 3, the introduction pipe 4 and its connecting part are removed and introduced in the package P after the contents C are sealed. The concern about the minimum use temperature of the tube 4 and the concern about the durability of the connection portion of the introduction tube 4 can be eliminated. Moreover, since the minimum use temperature of the introduction pipe 4 is higher than the minimum use temperature of the housing part 3, the relatively inexpensive introduction pipe 4 can be used, and the cost of the enclosure 1 can be reduced. Further, since the introduction channel 2 is provided so as to protrude from the peripheral edge 31 of the accommodation unit 3 toward the outside of the accommodation unit 3, the accommodation unit 3 can be physically operated during the sealing operation of the introduction channel 2. Therefore, it is easy to seal the introduction flow path 2.

  Further, the introduction channel 2 protrudes from the peripheral edge 31 of the housing part 3 toward the outside of the housing part 3, so that the width of the introduction channel 2 is increased at the upper edge 31 a, the lower edge 31 b, and the peripheral edge 31. And the width is narrower than any of the pair of side edge portions 31c. Thereby, it can suppress that the content C remains in the introduction flow path 2, and can make it easy to fill the accommodating part 3 with the content C. More specifically, if the width of the introduction flow path 2 is small and the volume of the introduction flow path 2 is sufficiently small, even if the contents C remain in the introduction flow path 2, the amount thereof becomes small.

  In addition, when the operation of sending the content C remaining in the introduction flow path 2 to the accommodating portion 3 by the action of a gas such as air is performed, the width of the introduction flow path 2 is set so that the upper edge portion 31a of the peripheral edge portion 31 is lower than the lower edge portion 31a. By being smaller than the width of each of the edge portion 31b and the pair of side edge portions 31c, the contents C remaining in the introduction flow path 2 can be more reliably delivered to the accommodating portion 3 by gas. In order to more smoothly perform the operation of sending the contents C from the introduction flow path 2 to the accommodating portion 3 by such a gas, for example, the width of the introduction flow path 2 is constant, and the introduction flow path 2 is cylindrical. It is desirable that the width of the introduction flow path 2 is equal to or approximately the same as the diameter of the introduction pipe 4.

  In addition, in the sealed container 1 of the present embodiment, it may be required that the error in the weight of the content C be within a range of several percent to 1% of the weight of the content C. In such a case, when the weight of the introduction flow path 2 from the sealing target position display unit 21 to the base end of the introduction flow path 2 is set to 1% or less of the target weight of the contents C, a part is welded. Thus, in the enclosure 1 in which the contents C are enclosed, the management problem after the contents C are enclosed can be solved.

  Specifically, for example, the accommodating portion 3 is sealed by welding at the sealing target position display portion 21 of the introduction flow path 2, and then, as described above, the sealing target position display portion at the distal end side of the introduction flow path 2. The introduction channel 2 is cut at a cutting position with reference to the boundary 21 or the sealing portion S. Thus, the weight of the introduction flow path 2 from the sealing target position display section 21 where the sealing section S is formed to the proximal end of the introduction flow path 2, that is, the storage section after the contents C are sealed in the storage section 3. The weight of the introduction flow path 2 remaining in 3 can be 1% or less of the target weight of the contents C. Therefore, the fluctuation of the weight of the enclosure 1 can be reduced, the error in the weight of the content C can be accurately measured, and the management problem of the content C can be solved. The weight of the introduction flow path 2 remaining in the accommodating portion 3 is, for example, as described above, from the weight of the enclosure 1 before cutting the introduction flow path 2 to the weight of a part of the cut introduction flow path 2. It can be measured by subtracting the design weight of the housing part 3.

  Further, the manufacturing method S100 of the present embodiment is a method of manufacturing the package P in which the contents C are introduced and sealed in the enclosing container 1 of the present embodiment described above. And the manufacturing method S100 of the package of this embodiment introduce | transduced in the accommodation process S2 which accommodates the content C in the accommodating part 3 via the introduction flow path 2, and the sealing target position display part 21 as mentioned above. It has sealing process S3 which seals the said accommodating part 3 by welding the flow path 2, and cutting | disconnection process S4 which cut | disconnects the introduction flow path 2. FIG. According to the package manufacturing method S100 of the present embodiment having the above steps, as described above, in the sealed container 1 in which the contents C are sealed by being partially welded, the management after the contents C are sealed. The above problem can be solved.

  As described above, according to the sealed container 1 and the manufacturing method S100 of the package of the present embodiment, as described above, in the sealed container 1 in which a part C is welded and the contents C are sealed, sealing by welding is performed. It is easy to stop and can solve the management problem after the contents C are sealed.
