Summary of the Invention

Problems to be Solved by the Invention

[0004] The pipette (mixing container) as described in Patent Document 1 above may be transported separately from the main container in a medical container. As an example of such a transportation mode, from the viewpoint of cost, etc., a packing box in which a plurality of pipettes are irregularly accommodated is transported. In this case, there is a concern that the sealing body may be damaged or broken due to contact or collision between the pipettes during transportation of the packing box. As countermeasures against such concerns, it is conceivable to change the material of the sealing body to a plastic film, attach a reinforcing body such as a label to the sealing body, etc. However, if these countermeasures are simply implemented, there is a concern that the inside of the pipette cannot be sufficiently sterilized during the sterilization process.

[0005] An object according to one aspect of the present invention is to provide a multi-infusion container capable of satisfactorily performing high-pressure steam sterilization treatment while suppressing damage to a sealing body during transportation, and a medical container including the multi-infusion container.

Means for Solving the Problems

[0006] The multi-infusion container according to one aspect of the present invention includes a storage portion that stores contents and has an opening, a sealing body that is a sterilization paper for sealing the opening, and a label that is attached to the surface of the sealing body. The sealing body has a covered portion that is covered by the label in a plan view and an exposed portion that is exposed from the label in a plan view and overlaps the opening.

[0007] In this multi-infusion container, a label is attached to the surface of the sealing body that seals the opening of the storage portion. Thereby, the sealing body is reinforced and protected by the label. Therefore, even when contact, collision, etc. occur between multi-infusion containers during transportation or the like, the sealing body is less likely to be damaged. In addition, the sealing body that is sterilization paper has a covered portion that is covered by the label in a plan view and an exposed portion that is exposed from the label in a plan view and overlaps the opening. Thereby, when the multi-infusion container is subjected to high-pressure steam sterilization treatment, the high-temperature high-pressure steam reaches the inside of the storage portion through the exposed portion. Therefore, the high-pressure steam sterilization treatment of the multi-infusion container can be satisfactorily performed.

[0008] The outer edge of the label has a first line portion and a second line portion that are spaced apart from each other, and at least a part of the first line portion and at least a part of the second line portion may be located closer to the center of the opening than the edge of the opening. In this case, since a plurality of exposed portions are provided in the sealing body, the high-pressure steam sterilization treatment of the multi-infusion container can be performed more satisfactorily.

[0009] The outer edge of the label may further include a first connecting portion that connects one end of the first linear portion and one end of the second linear portion and extends in an arc shape, and a second connecting portion that connects the other end of the first linear portion and the other end of the second linear portion and extends in an arc shape. In this case, since the area of the label is smaller compared to a label having a circular shape in plan view where the first linear portion and the second linear portion are arc-shaped, the number of labels that can be formed from a single sheet member can be increased.

[0010] The covering portion has an unpasted portion that is not pasted to the label, and a part of the unpasted portion may overlap the opening portion and correspond to a part of the outer edge of the label. In this case, a part of the unpasted portion is in a state where it can be exposed to the outside air. Therefore, the high-temperature high-pressure steam reaches the inside of the accommodating portion not only through the exposed portion but also through a part of the unpasted portion and the opening portion overlapping the part. Therefore, the high-pressure steam sterilization treatment of the multi-dose container can be carried out better.

[0011] The unpasted portion may have a strip shape extending from one end to the other end of the outer edge of the label in the first direction in plan view. In this case, the high-pressure steam sterilization treatment of the multi-dose container can be carried out even better, and the penetration strength of the laminate of the sealing body and the label is improved.

[0012] The back surface of the label may have a non-adhesive portion that overlaps the unpasted portion and is subjected to anti-pasting processing. In this case, the penetration strength of the laminate of the sealing body and the label is further improved.

[0013] A multi-dose container according to another aspect of the present invention includes an accommodating portion that accommodates the content and has an opening portion, a sealing body that is a sterilization paper for sealing the opening portion, and a label that is adhered to the surface of the sealing body. The sealing body has a covering portion that is covered by the label in plan view. The covering portion has an unpasted portion that is not pasted to the label, and a part of the unpasted portion overlaps the opening portion and corresponds to a part of the outer edge of the label.

[0014] In this mixed injection container, a label is attached to the surface of the sealing body that seals the opening of the accommodating portion. As a result, the sealing body is reinforced and protected by the label. Therefore, even when contact or collision occurs between the mixed injection containers during transportation or the like, the sealing body is less likely to be damaged. In addition, the covering portion has an unapplied portion that is not attached to the label, and a part of the unapplied portion overlaps the outer edge of the label. As a result, a part of the unapplied portion is in a state where it can be exposed to the outside air. Therefore, when the mixed injection container is subjected to high-pressure steam sterilization, the high-temperature high-pressure steam reaches the inside of the accommodating portion through a part of the unapplied portion and the opening overlapping the part. Therefore, the high-pressure steam sterilization treatment of the mixed injection container can be carried out well.

[0015] The unapplied portion may have a strip shape extending from one end to the other end of the outer edge of the label in the first direction in a plan view. In this case, the high-pressure steam sterilization treatment of the mixed injection container can be carried out even better, and the penetration strength of the laminate of the sealing body and the label is improved.

[0016] The back surface of the label may have a non-adhesive portion that overlaps the unapplied portion and is subjected to anti-pasting treatment. In this case, the penetration strength of the laminate of the sealing body and the label is further improved.

[0017] The entire label may be located inside the outermost edge of the accommodating portion in a plan view. In this case, since folding of the label is prevented, peeling of the label from the sealing body is less likely to occur.

[0018] The penetration strength of the label may be lower than the penetration strength of the sterilization paper. In this case, when contact or collision occurs between the mixed injection containers during transportation or the like, only the sterilization paper is less likely to be damaged. Therefore, defective products that cannot be detected visually are less likely to occur.

[0019] The main part of the label may be art paper. In this case, when contact or collision occurs between the mixed injection containers during transportation or the like, only the sterilization paper is less likely to be damaged. Therefore, defective products that cannot be detected visually are less likely to occur.

[0020] One aspect of the present invention may be a medical container including the above-mentioned admixture container and a container body to which the admixture container is attached.

Advantages of the Invention

[0021] According to one aspect of the present invention, it is possible to provide an admixture container capable of satisfactorily performing high-pressure steam sterilization treatment while suppressing damage to the sealing body during transportation and a medical container including the admixture container.

Embodiments for Carrying Out the Invention

[0023] Hereinafter, with reference to the accompanying drawings, a preferred embodiment of one aspect of the present invention will be described in detail. In the following description, the same reference numerals will be used for the same elements or elements having the same function, and redundant descriptions will be omitted.

[0024] FIG. 1 is a front view showing a medical container including a mixing container according to an embodiment. The medical container 100 shown in FIG. 1 is a member that can prepare, for example, a chemical solution for infusion and is configured to be able to easily drain the chemical solution. The medical container 100 is an assembly having a main container 1 that houses a first content, a mixing container 2 that is connected to the main container 1, and a suspension tool 3 that is attached to the mixing container 2. In the medical container 100, a second content housed in another container (not shown) such as a vial attached to the mixing container 2 can be supplied to the main container 1 while maintaining a sterile state. Thereby, the first content housed in the main container 1 and the second content are mixed while maintaining the sterile state, and a chemical solution is prepared. The prepared chemical solution can be poured out from the main container 1 to the outside. When one of the first content and the second content is a liquid, it is preferable that the first content is a liquid and the second content is a solid such as powder. In this case, the first content can function as a dissolution solution for the second content. Each of the first content and the second content is a physiological saline solution, a glucose solution, distilled water, a potassium chloride-containing solution, an antibiotic, a blood preparation, or the like.

[0025] Hereinafter, the state in which the medical container 100 is upright corresponds to the state of the medical container 100 shown in FIG. 1. For this reason, the vertical direction on the paper surface in FIG. 1 corresponds to the vertical direction of the medical container 100. Further, the left-right direction on the paper surface in FIG. 1 may be referred to as the first direction, and the direction orthogonal to the vertical direction and the first direction may be referred to as the second direction. In the present embodiment, the sterilization process of the mixing container 2 in the medical container 100 is performed in a state where the mixing container 2 is connected to the main container 1. Here, since the main container 1 and the mixing container 2 are airtightly integrated with each other, at least the sterile state inside the mixing container 2 in the medical container 100 is maintained.

[0026] The main container 1 is a member for storing the first content in a sterile state. The main container 1 includes a container body 10 for storing the first content, a first opening 11 provided on the container body 10, a first stopper 12 for sealing the first opening 11, a second opening 13 provided on the container body 10, and a second stopper 14 for sealing the second opening 13. In this embodiment, the first opening 11 is provided at the upper end of the container body 10, and the second opening 13 is provided at the lower end of the container body 10, but it is not limited thereto. At least a part of the first stopper 12 includes a rubber part (not shown) through which a double-headed needle 21 (details will be described later) provided in the admixture container 2 can penetrate. The second stopper 14 has a main body part 14a attached to the second opening 13 and a lid seal 14b attached to the tip of the main body part 14a. Although not shown, a rubber stopper is provided on the main body part 14a. The lid seal 14b is a member that is peeled off immediately before use of the medical container 100. Due to the presence of the lid seal 14b, the sterile state inside the medical container 100 is maintained.

[0027] The container body 10 has flexibility, and thus can be deformed according to changes in the internal pressure of the container body 10. The container body 10 is, for example, a molded body of a resin such as polyolefin such as polyethylene and polypropylene, or polyester such as polyethylene terephthalate. The first opening 11 and the second opening 13 are molded simultaneously with the container body 10. The parts for fixing the rubber parts in the first stopper 12 and the second stopper 14 are, for example, molded bodies of the resin as described above.

[0028] Figure 2 is a schematic cross-sectional view of the admixture container. As shown in FIGS. 1 and 2, the admixture container 2 is a member used for supplying the content of another container (for example, the second content) to the inside of the main container 1 while maintaining the sterile state. The admixture container 2 has a main body 20, a double-headed needle 21 housed in the main body 20, a support 22 for supporting the double-headed needle 21, and a lid material C attached to the main body 20.

[0029] The main body 20 is a hollow member having a bottomed cylindrical shape and is connected to the first stopper 12 of the main container 1. The main body 20 houses the double-ended needle 21 and the support 22 as contents. Therefore, the main body 20 can function as a housing portion for housing the above-mentioned contents. The main body 20 includes a first cylindrical portion 20a, a second cylindrical portion 20b connected to the upper end of the first cylindrical portion 20a, an annular bottom portion 20c closing a part of the lower end of the first cylindrical portion 20a, a first opening 20d defined by the upper end of the second cylindrical portion 20b, and a second opening 20e defined by the inner edge of the bottom portion 20c. The central axis of the main body 20 coincides with the center of the first cylindrical portion 20a, the center of the second cylindrical portion 20b, the center of the first opening 20d, and the center of the second opening 20e. A pair of first protruding portions 20f protruding in the radial direction of the main body 20 are provided on the outer surface of the second cylindrical portion 20b, and an annular second protruding portion 20g protruding downward is provided on the bottom surface of the bottom portion 20c. A step 20h is provided at the connection portion between the first cylindrical portion 20a and the second cylindrical portion 20b. The step 20h is formed, for example, by a part of the central portion of the second cylindrical portion 20b being recessed toward the second opening 20e. In plan view, the step 20h extends in the circumferential direction along the inner surface of the main body 20.

[0030] The double-ended needle 21 is a part of the contents housed in the main body 20 and is a hollow member used for communicating the main container 1 with another container. The double-ended needle 21 extends along the vertical direction like a shaft, for example, and the tip of the double-ended needle 21 is sharp. In plan view, the double-ended needle 21 overlaps the first opening 20d and the second opening 20e. The double-ended needle 21 includes a first puncture needle 21a, a second puncture needle 21b, and a pipe portion 21c. The first puncture needle 21a is a portion located at the lower end of the double-ended needle 21 and extends toward the first stopper 12. The second puncture needle 21b is a portion located at the upper end of the double-ended needle 21 and extends toward the lid member C. The pipe portion 21c is a hollow portion extending linearly between the first puncture needle 21a and the second puncture needle 21b. The pipe portion 21c forms a passage through which liquid can flow.

[0031] The support body 22 is a part of the content accommodated in the main body 20, and is a member that supports the double-ended needle 21 and is locked to the main body 20. The support body 22 has a plate-shaped substrate portion 22a that supports the double-ended needle 21, a peripheral wall portion 22b provided along the edge of the substrate portion 22a, and a plurality of claw portions 22c provided on the outer surface of the peripheral wall portion 22b.

[0032] The substrate portion 22a is the portion through which the double-ended needle 21 penetrates and has a substantially disk shape. The edge of the substrate portion 22a is located, for example, near the inner surface of the first cylindrical portion 20a. The peripheral wall portion 22b is a cylindrical portion extending from the substrate portion 22a toward the lid member C. In plan view, the peripheral wall portion 22b surrounds the second puncture needle 21b. The plurality of claw portions 22c are portions that are locked to the inner surface of the step 20h of the main body 20, and the plurality of claw portions 22c arranged along the circumferential direction are elastically deformable so as to bend in the radial direction.

[0033] When the support body 22 is accommodated in the main body 20, each claw portion 22c of the support body 22 is located on the inner surface of the step 20h of the main body 20. Thereby, the support body 22 is locked to the main body 20. Here, by pressing the support body 22 toward the second opening 20e of the main body 20, each claw portion 22c bends radially inward. Thereby, the locking of the support body 22 to the main body 20 is released, and the support body 22 becomes movable within the main body 20 so as to approach the second opening 20e. For example, in order to attach another container to the support body 22, the support body 22 is pressed toward the second opening 20e through the other container. Thereby, the support body 22 moves toward the main container 1, and the first puncture needle 21a punctures the first stopper 12 of the main container 1. Then, the second puncture needle 21b punctures the stopper of the other container. Note that after the second puncture needle 21b punctures the stopper of the other container, the first puncture needle 21a may puncture the first stopper 12 of the main container 1. As described above, the inside of the main container 1 and the inside of the other container communicate with each other through the double-ended needle 21.

[0034] The body 20, the double-ended needle 21, and the support 22 are each, for example, a resin molded body such as a polyolefin, polyester, polycarbonate, or ABS resin. In the present embodiment, the support 22 is integrally formed with the double-ended needle 21, but is not limited thereto. For example, the double-ended needle 21 may be fitted to the support 22 or welded to the support 22.

[0035] FIG. 3 is a schematic plan view of a lid member attached to the main body. As shown in FIG. 3, the lid member C is a laminate having a sealing body 23 and a label 24 attached to the surface of the sealing body 23. The sealing body 23 is a sheet-like member that seals the first opening 20d of the main body 20. The sealing body 23 is attached to the outer end portion 20i that defines the first opening 20d in the second cylindrical portion 20b. Although not shown, the sealing body 23 has a tab portion that is bent at the outer end portion 20i. The user can grip the tab portion and peel the sealing body 23 from the main body 20. The sealing body 23 may have a plurality of tab portions. The sealing body 23 is sterilized paper. The sterilized paper is a member processed so that gases such as gas or steam can pass through, but bacteria cannot pass through. The material of the sterilized paper is, for example, pulp fibers used for paper, melt thermoplastic resins used for non-woven fabrics, and the like. The melt thermoplastic resin is, for example, polyethylene, polypropylene, polyamide, or the like. In the present embodiment, the sealing body 23 is paper-based sterilized paper made of pulp fibers. Thereby, when a high-temperature sterilization treatment such as an autoclave is performed on the medical container 100, high-temperature steam passes through the sterilized paper. Thereby, the inside of the main body 20 (for example, the support 22, etc.) can be sterilized well.

[0036] The sealing body 23 has a covered portion 23a covered by the label 24 in a plan view, a first exposed portion 23b exposed from the label 24 and overlapping the first opening 20d, and a second exposed portion 23c exposed from the label 24. In the present embodiment, the entire covered portion 23a is attached to the label 24, and two first exposed portions 23b are provided on the sealing body 23. Thereby, even when the entire label 24 is attached to the sealing body 23, vapor or the like entering the inside of the main body 20 through the sealing body 23 can easily circulate. In a plan view, each of the two first exposed portions 23b has an arcuate shape having an arc portion and a straight portion, but is not limited thereto. The number of the first exposed portions 23b provided on the sealing body 23 is not limited. For example, a plurality of first exposed portions 23b may be provided at positions overlapping the first opening 20d in the covered portion 23a. In this case, each first exposed portion 23b has, for example, a circular shape, and the size of each first exposed portion 23b may be such that vapor can enter the inside of the main body 20.

[0037] In a plan view, the two first exposed portions 23b are point-symmetric to each other with respect to the center of the main body 20, but are not limited thereto. The shapes of the two first exposed portions 23b may be different from each other. In a plan view, the ratio of the area of the first opening 20d overlapping the first exposed portion 23b is, for example, 2.0% or more and 5.0% or less, 2.2% or more and 4.5% or less, 2.5% or more and 4.0% or less, and the like. In other words, in a plan view, the ratio of the area of the first opening 20d overlapping the sealing body 23 and the label is, for example, 95% or more and 98% or less, 95.5% or more and 97.8% or less, 96% or more and 97.5% or less, and the like. In this case, the inside of the main body 20 can be sterilized well, and breakage of the sealing body 23 can be suppressed well.

[0038] From the viewpoint of suppressing breakage during transportation of the multi-infusion container 2, the higher the piercing strength of the sealing body 23, the better, for example, 20 N or more, 25 N or more, 30 N or more, and the like. The piercing strength of the sealing body 23 can be obtained, for example, by measuring it by a method conforming to the content of "JIS Z 1707:2019, General Rules for Plastic Films for Food Packaging 7.5 Piercing Strength Test".

[0039] The label 24 is a sheet member that functions as a reinforcing member for reinforcing the sealing body 23 and also functions as a display portion indicating the use and the like of the admixture container 2. The entire label 24 is located inside the outermost edge of the main body 20 in a plan view. Thereby, folding of the corners of the label 24 does not occur. In the present embodiment, the outer edge OE of the label 24 has both a straight-line-shaped portion and a curved portion having an arc shape. Specifically, the outer edge OE of the label 24 is formed by a first line portion OE1 and a second line portion OE2 that extend linearly and are spaced apart from each other, and a first arc portion OE3 and a second arc portion OE4 that extend in an arc shape and are spaced apart from each other. In the outer edge OE, the ratio occupied by the first line portion OE1 and the second line portion OE2 is, for example, 30% or more and 36% or less, but is not limited thereto, and may be 31% or more and 35.5% or less, or may be 32% or more and 35% or less. Each of the first arc portion OE3 and the second arc portion OE4 protrudes outward in the radial direction of the label 24 in a plan view, but is not limited thereto. Each of the first arc portion OE3 and the second arc portion OE4 may protrude inward in the radial direction of the label 24 in a plan view. The above-described radial direction is a direction parallel to the direction in which the first line portion OE1 and the second line portion OE2 extend.

[0040] Each of the first line portion OE1 and the second line portion OE2 does not have to extend linearly, and may be, for example, a curve. For example, at least one of the first line portion OE1 and the second line portion OE2 may extend in an arc shape. In this case, each of the first line portion OE1 and the second line portion OE2 may protrude outward in the radial direction of the label 24 in a plan view, or may protrude inward in the radial direction of the label 24. As described above, when each of the first arc portion OE3 and the second arc portion OE4 protrudes outward or inward in the radial direction of the label 24, the directions in which the first line portion OE1 and the second line portion OE2 protrude may intersect or be orthogonal to each other with respect to the directions in which the first arc portion OE3 and the second arc portion OE4 protrude in a plan view.

[0041] The first line portion OE1 and the second line portion OE2 each extend in the second direction and are positioned point-symmetrically with respect to the center of the label 24. The first line portion OE1 constitutes one end of the label 24 in the first direction, and the second line portion OE2 constitutes the other end of the label 24 in the first direction. At least a part of the first line portion OE1 and at least a part of the second line portion OE2 are each located closer to the center of the first opening 20d than to the edge of the first opening 20d. For this reason, in a plan view, one of the first exposed portions 23b of the sealing body 23 is defined by the edge of the first opening 20d and at least a part of the first line portion OE1, and another one of the first exposed portions 23b of the sealing body 23 is defined by the edge of the first opening 20d and at least a part of the second line portion OE2. The first arc portion OE3 is a portion (first connection portion) connecting one end of the first line portion OE1 and one end of the second line portion OE2, and the second arc portion OE4 is a portion (second connection portion) connecting the other end of the first line portion OE1 and the other end of the second line portion OE2. The first arc portion OE3 and the second arc portion OE4 are positioned point-symmetrically with respect to the center of the label 24. The first arc portion OE3 constitutes one end of the label 24 in the second direction, and the second arc portion OE4 constitutes the other end of the label 24 in the second direction.

[0042] The label 24 has a main portion 24a and end portions 24b and 24c. The main portion 24a is a portion including the first line portion OE1, the second line portion OE2, and the center of the label 24. In the present embodiment, the main portion 24a has a strip shape extending from one end to the other end of the outer edge OE of the label 24 in the first direction in a plan view. For this reason, the main portion 24a has a rectangular shape having the first line portion OE1 and the second line portion OE2 as one side each in a plan view. The end portion 24b is an arcuate portion including the first arc portion OE3, and the end portion 24c is an arcuate portion including the second arc portion OE4. The area occupied by the main portion 24a in the label 24 is, for example, 40% or more and 80% or less, but is not limited thereto, and may be 45% or more and 70% or less, or may be 50% or more and 65% or less.

[0043] The label 24 is a sheet processed product made of paper or resin. An adhesive for adhering to the sealing body 23 is provided on the back surface of the label 24. The label 24 may have a single-layer structure or a laminated structure. When the main part of the label 24 is a paper sheet processed product, the main part is, for example, art paper or the like. When the main part of the label 24 is a resin sheet processed product, the main part is, for example, a foamed polyester film or the like. From the viewpoint of suppressing damage to the sealing body 23 during transportation of the multi-infusion container 2, it is preferable that the penetration strength of the label 24 is high. However, if the penetration strength of the label 24 is too high, only the portion of the sealing body 23 covered by the label 24 may be damaged. In this case, there is a possibility that the medical container 100 in which the sterile state of the multi-infusion container 2 is not maintained is manufactured, and that the medical container 100 becomes a defective product that cannot be visually detected. Therefore, the penetration strength of the label 24 may be lower than the penetration strength of the sealing body 23. In this case, the possibility that only the sealing body 23 is damaged can be favorably reduced. In the present embodiment, from the viewpoint of the reinforcing member of the label 24, the penetration strength of the label 24 may be, for example, 70% or more and 98% or less of the penetration strength of the sealing body 23, or 75% or more and 97% or less, or 80% or more and 95% or less.

[0044] At least a part of the surface of the label 24 is colored by a paint such as UV curable ink. Therefore, a color, pattern, characters, etc. are printed on at least a part of the surface of the label 24. From the viewpoint of visibility and the like, white characters may be provided in the center of the label 24.

[0045] The suspension tool 3 is a string-like member used when hanging the medical container 100 on a hook or the like, and is rotatably attached to the multi-infusion container 2. One end of the suspension tool 3 is rotatably hooked to one of the pair of first protrusions 20f, and the other end of the suspension tool 3 is rotatably hooked to the other of the pair of first protrusions 20f. The suspension tool 3 is, for example, an elastically deformable resin molded body, but is not limited thereto.

[0046] The operational effects of the mixing container 2 according to the present embodiment described above will be described with reference to FIG. 4. FIG. 4 is a schematic diagram showing a state in which a plurality of mixing containers are housed in a box. In FIG. 4, the box B is transparent, but it is not limited thereto.

[0047] For example, as shown in FIG. 4, when a plurality of mixing containers 2 are housed in the box B, contact, collision, etc. between the mixing containers 2 may occur. At this time, one mixing container 2 may collide with the first protruding portion 20f of another mixing container 2. Here, in the mixing container 2 according to the present embodiment, a label 24 is attached to the surface of the sealing body 23 that seals the first opening 20d of the main body 20. The sealing body 23 is reinforced and protected by the label 24. Therefore, even if a collision of the first protruding portion 20f as described above occurs, the sealing body 23 is less likely to be damaged. In addition, the sealing body 23, which is sterilization paper, has a covering portion 23a covered by the label 24 in a plan view and a first exposed portion 23b exposed from the label 24 in a plan view and overlapping the first opening 20d. Thereby, when the mixing container 2 is subjected to high-pressure steam sterilization treatment, the high-temperature high-pressure steam reaches the inside of the main body 20 through the first exposed portion 23b. Therefore, the high-pressure steam sterilization treatment of the mixing container 2 can be satisfactorily performed.

[0048] In the present embodiment, the outer edge OE of the label 24 has a first line portion OE1 and a second line portion OE2 that extend linearly and are spaced apart from each other, and at least a part of the first line portion OE1 and at least a part of the second line portion OE2 are each located closer to the center of the first opening 20d than to the edge of the first opening 20d. For this reason, a plurality of first exposed portions 23b are provided in the sealing body 23. Therefore, during the high-pressure steam sterilization process of the medical container 100, the high-temperature steam easily circulates inside the mixing container 2. Therefore, the inside of the main body 20 such as the double-headed needle 21 can be more satisfactorily sterilized by high-pressure steam.

[0049] In the present embodiment, the outer edge OE of the label 24 includes a first arc portion OE3 that connects one end of the first line portion OE1 and one end of the second line portion OE2 and extends in an arc shape, and a second arc portion OE4 that connects the other end of the first line portion OE1 and the other end of the second line portion OE2 and extends in an arc shape. Therefore, compared with a label having a circular shape in plan view, the area of the label becomes smaller, so that the number of labels 24 that can be formed from a single sheet member can be increased. Thus, the manufacturing cost of the label 24 can be reduced.

[0050] In the present embodiment, the entire label 24 is located inside the outermost edge of the main body 20 in plan view. For this reason, corner folding or the like of the label 24 does not occur. Thus, it is possible to prevent the label 24 from floating from the sealing body 23 due to folding of the label 24, so that peeling of the label 24 from the sealing body 23 is less likely to occur.

[0051] In the present embodiment, the penetration strength of the label 24 may be lower than the penetration strength of the sterilization paper forming the sealing body 23. In this case, when contact, collision, or the like occurs between the mixed injection containers 2 during transportation or the like, only the sterilization paper, that is, the sealing body 23 is less likely to be damaged. Thus, defective products that cannot be detected visually are less likely to occur.

[0052] Next, a mixed injection container according to a modified example will be described with reference to FIG. 5. Descriptions that overlap with those of the above-described embodiment in the description of the modified example will be omitted, and different portions will be described. That is, within the technically possible range, the descriptions of the above-described embodiment may be appropriately used for the modified example.

[0053] Fig. 5(a) is a schematic plan view showing a lid member according to a modified example, and Fig. 5(b) is a schematic bottom view showing a label according to the modified example. As shown in Figs. 5(a) and 5(b), the covering portion 23a of the sealing body 23A included in the lid member C1 of the mixed injection container 2A according to the modified example is defined by a dashed-dotted line in Fig. 5(a) and has an unapplied portion 23d that is not attached to the label 24A. A part of the unapplied portion 23d overlaps the first opening 20d of the main body 20 and corresponds to a part of the outer edge OE of the label 24A. In other words, a part of the unapplied portion 23d is not surrounded by the portion attached to the label 24A in the covering portion 23a. The unapplied portion 23d is a portion separable from the label 24A and is communicable with the outside air. The unapplied portion 23d has a strip shape extending from one end to the other end of the outer edge OE of the label 24A in the first direction in plan view. The one end of the outer edge OE corresponds to at least a part of the first line portion OE1, and the other end of the outer edge OE corresponds to at least a part of the second line portion OE2, but is not limited thereto. In this modified example, the one end of the outer edge OE coincides with the first line portion OE1, and the other end of the outer edge OE coincides with the second line portion OE2. Therefore, both edges of the unapplied portion 23d in the first direction coincide with a part of the first line portion OE1 and a part of the second line portion OE2, respectively, in plan view. Also, all or most of the portions other than the both edges at the edge of the unapplied portion 23d (that is, both edges of the unapplied portion 23d in the second direction) are defined by the portion attached to the label 24A in the covering portion 23a. For this reason, there are at least two portions where the portion attached to the label 24A exists in the covering portion 23a.

[0054] As shown in FIG. 5(b), the back surface of the label 24A has a non-adhesive portion 24d that overlaps the non-attached portion 23d of the sealed body 23A, and adhesive portions 24e and 24f that can be attached to the sealed body 23A. The non-adhesive portion 24d is a portion that does not exhibit adhesion (adhesion) to the sealed body 23A. The non-adhesive portion 24d is a portion of the label 24A where no adhesive or glue is provided, or a portion where a process for killing adhesion (glue killing process) has been performed. In the latter case, the glue killing process is performed by applying varnish or the like to the portion corresponding to the non-adhesive portion 24d. When glue killing process is performed, the shape of the non-adhesive portion 24d (as well as the shapes of the adhesive portions 24e and 24f) can be freely set. In this modified example, the shape of the non-adhesive portion 24d is a rectangle that matches the shape of the main portion 24a, but is not limited to this. The non-adhesive portion 24d is located between the adhesive portions 24e and 24f in the second direction. From the viewpoints of preventing peeling of the label 24A from the sealing body 23A, manufacturing costs, etc., the proportion of the non-adhesive portion 24d in the label 24A may be 40% or more and 80% or less, 45% or more and 70% or less, or 50% or more and 65% or less.

[0055] The adhesive parts 24e and 24f are parts that are attached to the sealing body 23A. The adhesive part 24e includes the first arc part OE3 and constitutes one end of the label 24A in the second direction, and the adhesive part 24f includes the second arc part OE4 and constitutes the other end of the label 24A in the second direction. The adhesive parts 24e and 24f are in a point-symmetric relationship with each other with respect to the center of the label 24A, but are not limited to this. In this modification, the shapes of the adhesive parts 24e and 24f are each bow-shaped to match the shapes of the ends 24b and 24c, but are not limited to this.

[0056] In the above-described modification, for example, a gap is generated between the non-attached portion 23d and the label 24A during the high-pressure steam sterilization process of the medical container 100, and high-temperature steam enters the inside of the main body 20 through the non-attached portion 23d exposed in the gap. For this reason, the high-pressure steam sterilization process can be carried out better. In addition, due to the existence of the above gap, the airtightness inside the main body 20 can be intentionally reduced during the high-pressure steam sterilization process, so that the expansion and deformation of the label 24A after the high-pressure steam sterilization process can also be suppressed well. In addition, different from the above-described embodiment, even when the sealing body does not include the first exposed portion, the high-pressure steam sterilization process can be carried out well through the above gap.

[0057] In addition, in the above modification, since a part of the label 24A can be separated from the sealing body 23A, it is possible to suppress all of the force applied to the label 24A from being directly transmitted to the sealing body 23A. Thereby, the combined penetration strength of the sealing body 23A and the label 24A (that is, the penetration strength of the lid material C1) can be further improved. Here, with reference to FIGS. 6 to 8, the above effects will be described in detail.

[0058] First, with reference to FIG. 6, the relationship between the penetration strength of the sterilization paper alone, the penetration strength of the label alone, and the penetration strength of the sterilization paper with the label attached will be described. FIG. 6 is a graph showing the penetration strength of the sterilization paper alone, the penetration strength of the label alone, and the penetration strength of the sterilization paper with the label attached. Each penetration strength shown in FIG. 6 was obtained in accordance with the content of "JIS Z 1707:2019, General Rules for Plastic Films for Food Packaging 7.5 Puncture Strength Test". Here, after fixing a sample (one side: 45 mm) such as sterilization paper to the pedestal of a universal testing machine (manufactured by Shimadzu Corporation, Autograph), a jig formed of the same material as the main body of the dispensing container is pressed against the sample at a speed of 100 mm / min. The sterilization paper to be measured is the sterilization paper MEP-P series manufactured by KJ Special Paper Co., Ltd. The label to be measured is art paper (basis weight: 110 g / m 2 ~115 g / m 2 and has been subjected to printing, adhesive application, and varnish application. The numerical value of each penetration strength is the average value of the measurement results of 5 samples.

[0059] As shown in FIG. 6, the penetration strength of the sterilized paper alone is higher than that of the label alone. Here, some of the labels attached to the sterilized paper are subjected to anti-pasting treatment. Therefore, it can be inferred that the penetration strength of the sterilized paper with the label attached is higher than the total value of the penetration strength of the sterilized paper alone and the penetration strength of the label alone.

[0060] Next, the durability of the lid material when the mixing containers collide with each other will be described with reference to FIG. 7. FIG. 7 is a schematic diagram for explaining the collision durability test. The durability of the lid material when the mixing containers collide with each other is obtained by causing the lid material of the other mixing container to collide with one mixing container fixed in a predetermined posture. Specifically, while one mixing container is fixed so that the first protruding portion faces upward, the other mixing container is dropped. At this time, by controlling the dropping posture of the other mixing container using the cylinder T, the lid material of the other mixing container is made to collide with the first protruding portion of one mixing container. The distance between the mixing containers in the vertical direction is increased by 10 cm each time, and the height at which the lid material is damaged is recorded. In the collision durability test, three types of samples (Sample I to Sample III) were used as the other mixing container. The lid material of Sample I is formed only of sterilized paper. The lid material of Sample II is formed of sterilized paper to which a label without anti-pasting treatment is attached. The lid material of Sample III is formed of sterilized paper to which a label subjected to anti-pasting treatment is attached.

[0061] FIG. 8 is a graph showing the results of the collision durability test of Samples I to III. The numerical values of each sample shown in FIG. 8 are the average values of five measurement results. As shown in FIG. 8, the numerical value of Sample III is the highest. Here, since the numerical value of Sample III is higher than that of Sample II, it can be inferred that the presence or absence of anti-pasting treatment is related to the penetration strength of the lid material. From the above, it can be said that the effect of being able to further improve the penetration strength of the laminate of the sealing body 23A and the label 24A is achieved by making a part of the label 24A separable from the sealing body 23A.

[0062] The dispensing container according to one aspect of the present invention is as described in, for example, the following [1] to

[13] , and these will be described in detail based on the above-described embodiment and the above-described modification examples.

[0063] However, one aspect of the present invention is not limited to the above embodiments, the above modifications, and the above [1] to

[13] . One aspect of the present invention can be further modified without departing from the gist thereof. For example, in the above embodiments and the above modifications, a main container having a first mouth portion and a second mouth portion is used, but the present invention is not limited thereto. FIG. 9 is a schematic front view showing another example of a medical container. As shown in FIG. 9, in a medical container 100A, a multi-injection container 2B may be airtightly attached to a main container 1A having only one mouth portion. The multi-injection container 2B has the same shape as the multi-injection container 2 of the above embodiment except that a first protruding portion for attaching a suspension tool is not provided. Note that the multi-injection container 2 of the above embodiment may be attached to the medical container 100A.

[0064] In the above-described embodiments and the above-described modification examples, the main body that functions as the storage portion of the mixed injection container is a single member, but the present invention is not limited thereto. The main body of the mixed injection container may be an assembly of two or more members. For example, the main body of the mixed injection container is provided with a first portion that is hermetically connectable to the main container and a second portion that is hermetically connectable to the first portion, and an opening is provided in the second portion. The mixed injection container may include a sealing body that is a sterilization paper for sealing the opening and a label that is attached to the surface of the sealing body. Each of the sealing body and the label in this case may have the structure disclosed in the above-described embodiment or the above-described modification example. The second portion may be a screw cap that is screwed onto the first portion, etc.

[0065] In the above-described embodiments and the above-described modification examples, a step is provided at the connection portion between the first cylindrical portion and the second cylindrical portion in the main body of the mixed injection container, but the present invention is not limited thereto. For example, the step may not be provided in the main body. In this case, a protrusion or the like for the support body to be hooked may be provided on the inner peripheral surface of the main body.

[0066] In the above-described embodiments and the above-described modification examples, the main portion of the label has a rectangular shape and the end portion of the label has an arcuate shape, but the present invention is not limited thereto. Also, the label may be translucent. In this case, since the entire sealing body can be visually recognized through the label, the penetration strength of the label may be made significantly higher than the penetration strength of the sealing body.

[0067] In the above-described modification example, the unadhered portion overlaps only the main portion of the label in a plan view, but the present invention is not limited thereto. For example, the unadhered portion may overlap not only the main portion of the label but also the end portion of the label. At this time, the unadhered portion may overlap only one end portion of the label or may overlap only both end portions of the label. Therefore, the unadhered portion is not limited to a rectangular shape. Also, in the above-described modification example, the pair of linear sides facing each other in the unadhered portion of the sealing body coincide with the first line portion and the second line portion of the outer edge of the label in a plan view, but the present invention is not limited thereto. The unadhered portion may be smaller than the main portion of the label.
