Description

The present invention relates to a labeled, multi-chamber container containing a fluid.

Medicinal solutions such as peritoneal dialysis solutions and infusions are generally prepared by blending multiple medications. Some combinations of medications change over time when combined. In such cases, the medications are mixed immediately before administration to the patient. Multi-chamber containers with multiple storage chambers are used to store these medications. Multi-chamber containers include a container body made of a flexible sheet. The container body has multiple storage chambers separated by partitions formed by peelably joining opposing flexible sheets. At least a portion of the medications stored in each of the multiple storage chambers are liquid. When an operator (healthcare worker, patient, etc.) manually presses on a storage chamber containing such medication, the pressure within the storage chamber increases, the partition opens, the multiple storage chambers become connected, and the medications stored in each storage chamber are mixed.

In order to prevent unmixed medication from being administered to patients, it has been proposed to attach a hanging hole closure member of a specified structure to the hanging hole of a multi-chamber container so that an operator cannot hang the multi-chamber container on a hanger or hook when the partition is not open (Patent Document 1).
In order to encourage workers to open the partition, it has been proposed to attach a label to the container body that cannot be replaced within the designated label attachment frame when the partition is not open (Patent Document 2).

However, the hanging hole closure member of Patent Document 1 makes it difficult for an operator to visually detect that the partition has been opened. Furthermore, since the hanging hole closure member can be restored to its original state after the partition has been opened, there is a risk of misuse. Furthermore, there are problems such as the difficulty of attaching the hanging hole closure member to a multi-chamber container, and the fact that the hanging hole closure member is thick makes it difficult to stack multi-chamber containers equipped with the hanging hole closure member.
In the label of Patent Document 2, it is also difficult for an operator to visually detect that the partition has been opened, and the label can be restored to its original state after the partition has been opened.

The object of the present invention is to provide a label for a multi-chamber fluid-filled container that allows the opening of the partition to be clearly visually confirmed and that does not return to its pre-opening state after the partition is opened, as well as a labeled multi-chamber fluid-filled container using the same.

(Multi-chamber container containing fluid)
The fluid-filled multi-chamber container 1 to which the label 10 of this embodiment is affixed is a multi-chamber container 2 in which a chemical liquid L1 is contained in a first storage chamber S1 and a chemical liquid L2 is contained in a second storage chamber S2 (another storage chamber).
The multi-chamber container 2 includes a container body 3 and a chemical solution discharge member 4. The container body 3 is substantially rectangular and is composed of a pair of opposing flexible sheets 31 and 32.
A circular hanging hole 34 is formed in a first edge 33 at one end in the first direction (the vertical direction in FIG. 3 ) of the periphery of the container body 3. A chemical solution discharge member 4 is attached to a second edge 35 at the other end in the first direction.

The container body 3 is provided with a partition 36 formed by peelably joining opposing flexible sheets 31, 32 along a second direction perpendicular to the first direction. The partition 36 divides the interior of the container body 3 into a first storage chamber S1 and a second storage chamber S2. Of these storage chambers S1, S2, the first storage chamber S1 is located closest to the first edge portion 33.
"Peelable" means that flexible sheet 31 and flexible sheet 32 peel off when either or both of the first storage chamber S1 containing drug solution L1 and the second storage chamber S2 containing drug solution L2 are pressed.

The chemical solution discharge member 4 is a substantially cylindrical member for discharging the chemical solution from the container body 3 .
The chemical solution discharge member 4 is sandwiched between a pair of flexible sheets 31 and 32, and the outer circumferential surface of the chemical solution discharge member 4 and the flexible sheets 31 and 32 are inseparably joined together.
At the peripheral edge of the container body 3 other than the position where the chemical solution discharge member 4 is attached, the opposing flexible sheets 31 and 32 are inseparably joined to each other.
"Non-peelable" means that flexible sheet 31 and flexible sheet 32 do not peel off when either or both of the first storage chamber S1 containing chemical solution L1 and the second storage chamber S2 containing chemical solution L2 are pressed.

Materials for the flexible sheets 31, 32 include resin, paper, etc., and can be appropriately selected depending on the application of the multi-chamber fluid-filled container 1. When the multi-chamber fluid-filled container 1 is for medical use, resin is generally used, and examples of resin include polypropylene, polyethylene, etc.
The chemical solution discharge member 4 is usually made of a resin, and examples of the resin include the same as those mentioned above.

(label)
The label 10 includes a substrate 11 and an adhesive layer 12. The adhesive layer 12 is provided on one surface of the substrate 11.
A release sheet 20 is laminated on the surface of the label 10 on the adhesive layer 12 side. The release sheet 20 is peeled off before the label 10 is attached to the multi-chamber container 1 containing a fluid.

The label 10 has a first region 13 and a second region 14. The first region 13 is an area that is attached to the first surface 3a of the container body 3 at the first edge portion 33. The second region 14 is an area that is attached to the second surface 3b opposite the first surface 3a of the container body 3 at a position corresponding to the first storage chamber S1. The first region 13 and the second region 14 are arranged side by side in the first direction.
The first surface 3 a is the surface of the flexible sheet 31 , and the second surface 3 b is the surface of the flexible sheet 32 .

A circular hole 15 is formed in the base material 11 in the first region 13. The hole 15 is formed so as to coincide with the hanging hole 34 when the first region 13 is attached to the first surface 3 a of the container body 3.
The adhesive layer 12 is provided along the first direction on both sides of the hole 15 in the second direction, and the adhesive layer 12 is not provided in the hole 15 portion.

A perforation 16 is provided at the boundary between the first region 13 and the second region 14 of the label 10 along a second direction perpendicular to the first direction.
Furthermore, the label 10 has cutouts 17 and 18 that extend inward from both edges of the label 10 in the second direction. Each of the cutouts 17 and 18 has a triangular shape with one vertex located on the boundary between the first region 13 and the second region 14 and becoming wider toward the outside. The cutouts 17 and 18 make the width of the boundary between the first region 13 and the second region 14 of the label 10 narrower than the remaining portions.
The perforated portion 16 and the cutout portions 17 and 18 form an easy-to-tear portion that makes it easy to cut between the first region 13 and the second region 14.

Examples of the substrate 11 include resin film, paper, nonwoven fabric, etc. Examples of resins constituting the resin film include polyolefins such as polypropylene and polyethylene, polyesters such as polyethylene terephthalate, polyvinyl chloride, polystyrene, etc. Examples of paper include cast-coated paper, art paper, coated paper, and high-quality paper. When the fluid-filled multi-chamber container 1 is for medical use, the substrate 11 is preferably a resin film, and polypropylene film is particularly preferred.
The thickness of the substrate 11 is preferably 5 to 300 μm, more preferably 20 to 100 μm. When the thickness of the substrate 11 is equal to or greater than the lower limit of the above range, the processability and protective properties are good, and when the thickness is equal to or less than the upper limit of the above range, the stackability is good.

The adhesive layer 12 is a layer containing an adhesive.
Examples of adhesives include acrylic, silicone, rubber, urethane, and vinyl ether adhesives. These adhesives include emulsion, solvent, and hot melt types, and any of these types can be used.
The adhesive is preferably an acrylic or silicone adhesive, since it is less likely to affect the contents of the multi-chamber container 2 .

The adhesive layer 12 may further contain other components as needed. Other optional components include tackifiers, adhesive microspheres, thickeners, pH adjusters, antifoaming agents, antiseptics and antifungals, pigments, inorganic fillers, stabilizers, wetting agents, humectants, etc. Examples of tackifiers include rosin-based resins, terpene-based resins, aliphatic petroleum resins, aromatic petroleum resins, hydrogenated petroleum resins, styrene-based resins, and alkylphenol resins.

The mass per unit area of the adhesive layer 12 is preferably 2 to 70 g/m ² , and more preferably 10 to 50 g/m ^2. When the mass per unit area of the adhesive layer 12 is equal to or greater than the lower limit of the above range, sufficient adhesive strength is obtained, and when the mass per unit area of the adhesive layer 12 is equal to or less than the upper limit of the above range, good usability is achieved, such as less stickiness at the cut edge.

The adhesive strength between the adhesive layer 12 and the first surface 3a of the container body 3 of the multi-chamber container 1 containing fluid is preferably 0.2 to 20 N/25 mm, more preferably 1.0 to 15 N/25 mm.
The adhesive strength is a value measured in an environment of 23°C in accordance with JIS Z-0237.

Examples of the release sheet 20 include a release sheet made by forming a sealing layer on the surface of paper as needed and then applying a release agent such as a silicone-based agent.

There are no particular limitations on the manufacturing method of label 10, and it may be the same as known label manufacturing methods. For example, label 10 can be manufactured by applying an adhesive to either the substrate 11 or the release sheet 20 to form an adhesive layer 12, bonding the substrate 11 and the release sheet 20 together via the adhesive layer 12, and then performing processes such as perforation, punching, and half-cutting on the resulting laminate.

(Multi-chamber container containing fluid with label)
The labeled, multi-chamber container 100 contains a multi-chamber container 1 containing fluid and a label 10 .
In the labeled multi-chamber container 100 containing fluid, the multi-chamber container 1 containing fluid is bent between the first edge portion 33 and a position corresponding to the first storage chamber S1 so that the second surfaces 3b face each other.
The first region 13 of the label 10 is attached to the first surface 3a of the container body 3 at the first edge 33. The second region 14 of the label 10 is attached to the second surface 3b of the container body 3 at a position corresponding to the first storage chamber S1.
The position of the boundary between the first region 13 and the second region 14, i.e., the position of the perforated portion 16, coincides with the position of the end of the multi-chambered fluid-containing container 1 on the first edge portion 33 side in the first direction.
The position of the hole 15 in the label 10 coincides with the position of the hanging hole 34 in the multi-chamber container 2 .

The labeled multi-chamber fluid-filled container 100 can be manufactured, for example, by attaching the first region 13 of the label 10 to the first surface 3a of the multi-chamber fluid-filled container 1 so that the position of the hole 15 in the label 10 coincides with the position of the hanging hole 34 in the multi-chamber fluid-filled container 2, folding the multi-chamber fluid-filled container 1 so that the second surfaces 3b face each other between the first edge portion 33 and a position corresponding to the first storage chamber S1, and then attaching the second region 14 of the label 10 to the second surface 3b of the container body 3. The first region 13 of the label 10 may also be attached to the first surface 3a after folding the multi-chamber fluid-filled container 1.

The labeled fluid-containing multi-chamber container 100 is used as follows.
First, pressure is applied to the second storage chamber S2 of the labeled fluid-containing multi-chamber container 100. This increases the pressure within the second storage chamber S2, and this pressure causes the flexible sheets 31 and 32 to separate at the partition 36 (opening the partition 36), causing the chemical liquid L2 to move toward the first storage chamber S1, and the chemical liquids L1 and L2 to mix together to form a mixed chemical liquid L3.
At this time, the first storage chamber S1 portion of the container body 3 expands more, which causes the end of the container body 3 on the first edge portion 33 side to rise, and a force is applied to the boundary portion between the first region 13 and the second region 14 of the label 10. As a result, the perforation portion 16 is cut, and the first region 13 and the second region 14 are separated as shown in Figure 6.
Next, a hook of a stand or the like is inserted into the hanging hole 34, and the multi-chamber container 2 is hung on the stand or the like.
Thereafter, the mixed medicinal liquid L3 is discharged via the medicinal liquid discharge member 4. In the case of medical use, the discharged mixed medicinal liquid L3 (such as an infusion) is administered to a patient.

In this embodiment, when the partition 36 of the labeled, fluid-containing, multi-chamber container 100 is opened, the first region 13 and the second region 14 of the label 10 are separated, allowing an operator to visually detect that the partition 36 has been opened. Furthermore, the separated first region 13 and second region 14 will not return to their original state, preventing incorrect use.
Furthermore, before the partition 36 is opened, the multi-chamber container 1 containing fluid is bent at a predetermined position, blocking the hanging hole 34 and preventing the insertion of a hook into the hanging hole 34. This urges the worker to open the partition 36, and prevents the labeled multi-chamber container 100 containing fluid from being used (for example, administering only the medicinal solution L2 to a patient) when the partition 36 is not opened.
Furthermore, since the label 10 only needs to be attached to the fluid-filled multi-chamber container 1, it is easier to set it on the fluid-filled multi-chamber container 1 than the hanging hole closure member described in Patent Document 1. Furthermore, since the label 10 is thinner than the hanging hole closure member described in Patent Document 1, the fluid-filled multi-chamber container 1 with the label 10 set thereon is easy to stack and has excellent storage properties.
Furthermore, since the adhesive layer 12 is not provided in the portion of the first region 13 corresponding to the hanging hole 34, the adhesive layer 12 in the hanging hole 34 portion does not stick to the hand or the hook after the first region 13 and the second region 14 are separated, which provides excellent usability. Note that, since the strength of the adhesive layer 12 is weak, even if the adhesive layer 12 is present in the hanging hole 34 portion, it is possible to insert a hook.

Second Embodiment
Fig. 7 is a schematic plan view of the label 40 according to the second embodiment, and Fig. 8 is a schematic cross-sectional view taken along the line VIII-VIII in Fig. 7.
In the following description, components corresponding to those described above will be denoted by the same reference numerals and detailed description thereof will be omitted.

The label 40 according to this embodiment includes a substrate 41 and an adhesive layer 12. The substrate 41 is a multilayer substrate in which a first layer 42 and a second layer 43 are adhered to each other in a manner that allows them to be peeled off but prevents them from being reattached after peeling (hereinafter also referred to as "pseudo-adhesion"). The adhesive layer 12 is provided on one surface of the substrate 41.
A release sheet 20 is laminated on the surface of the label 40 on the adhesive layer 12 side.
The label 40 is attached to the fluid-containing multi-chamber container 1 in the same manner as the label 10 of the first embodiment.
The label 40 is similar to the label 10 of the first embodiment except that it includes a substrate 41 instead of the substrate 11. The substrate 41 does not have the holes 15 formed therein.

The first layer 42 may be the same as the substrate 11 .
The thickness of the first layer 42 is preferably 5 to 400 μm, more preferably 20 to 300 μm. If the thickness of the first layer 42 is equal to or greater than the lower limit of the above range, the strength is high, and even if an attempt is made to insert a hook into the hanging hole 34 before peeling the first layer 42 from the second layer 43, the first layer 42 will not break and the insertion will not be possible. If the thickness of the first layer 42 is equal to or less than the upper limit of the above range, stacking properties are good.

A soft thermoplastic resin layer is preferred as the second layer 43. If the second layer 43 is made of a soft thermoplastic resin, a pseudo-adhesion state can be obtained regardless of the material of the first layer 42. Furthermore, if the second layer 43 is made of a soft thermoplastic resin, when the hook is inserted into the hanging hole 34 after the first layer 42 is peeled from the second layer 43, the second layer 43 covering the hanging hole 34 is easily torn.
Examples of soft thermoplastic resins include polyolefins such as polyethylene, polypropylene, and polybutene, polyvinyl chloride, polyvinylidene chloride, and polyester.
The thickness of the second layer 43 is preferably 1 to 50 μm, more preferably 5 to 30 μm. When the thickness of the second layer 43 is equal to or greater than the lower limit of the above range, the pseudo-adhesion stability is good. When the thickness of the second layer 43 is equal to or less than the upper limit of the above range, the second layer 43 is likely to tear when inserting a hook into the hanging hole 34 after peeling off the first layer 42.

The adhesive strength between the first layer 42 and the second layer 43 is preferably 100 to 3000 mN/25 mm, and more preferably 200 to 2000 mN/25 mm.
The adhesive strength between the first layer 42 and the second layer 43 is usually weaker than the adhesive strength between the adhesive layer 12 and the first surface 3 a of the container body 3. As a result, when an attempt is made to peel off the first region 13, the adhesive strength between the first layer 42 and the second layer 43 peels off before the adhesive strength between the adhesive layer 12 and the first surface 3 a of the container body 3 peels off.

There are no particular limitations on the manufacturing method of label 40, and it may be similar to known label manufacturing methods. For example, label 40 can be manufactured by applying a soft thermoplastic resin to one surface of first layer 42 to form second layer 43 to obtain substrate 41, applying an adhesive to either the surface of substrate 41 facing second layer 43 or release sheet 20 to form adhesive layer 12, bonding substrate 41 and release sheet 20 via adhesive layer 12, and then performing processes such as perforation, punching, and half-cutting on the resulting laminate.

The labeled multi-chamber fluid-containing container 1 with the label 40 attached thereto is used as follows.
First, the second storage chamber S2 of the labeled, fluid-containing, multi-chamber container is pressed, which opens the partition 36 and separates the first region 13 and the second region 14 of the label 40, as in the first embodiment.
At this time, as shown in FIG. 9 , the first region 13 of the label 40 is attached to the first edge portion 33, and the hanging hole 34 is covered by the base material 41. In this state, the hook cannot be inserted. Therefore, the first layer 42 of the base material 41 is peeled off from the second layer 43. After the first layer 42 is peeled off, the hanging hole 34 is covered only by the second layer 43, as shown in FIG. 10 . The second layer 43 is easily torn by inserting a hook. Therefore, the hook can be inserted into the hanging hole 34, and the multi-chamber container 2 can be hung on a stand or the like. After hanging the multi-chamber container 2 on a stand or the like, the mixed chemical solution L3 is discharged from the chemical solution discharge member 4 via the chemical solution discharge member 4.

In this embodiment, when the partition 36 of the labeled, fluid-containing, multi-chamber container is opened, the first region 13 and the second region 14 of the label 40 are separated, allowing an operator to visually detect that the partition 36 has been opened. Furthermore, the separated first region 13 and second region 14 will not return to their original state, preventing incorrect use.
Furthermore, before the partition 36 is opened, the multi-chamber fluid-filled container 1 is bent at a predetermined position, so the hanging hole 34 is blocked and it is not possible to insert a hook into the hanging hole 34. Furthermore, even after the first region 13 and the second region 14 are separated, it is not possible to insert a hook into the hanging hole 34 before the first layer 42 of the base material 41 is peeled off from the second layer 43. This urges the worker to open the partition 36, and prevents the labeled multi-chamber fluid-filled container from being used when the partition 36 is not opened (for example, administering only the medicinal solution L2 to a patient).
Furthermore, since the label 40 only needs to be attached to the fluid-filled multi-chamber container 1, it is easier to set on the fluid-filled multi-chamber container 1 than the hanging hole closure member described in Patent Document 1. Furthermore, since the label 40 is thinner than the hanging hole closure member described in Patent Document 1, the fluid-filled multi-chamber container 1 with the label 40 set thereon is easy to stack and has excellent storage properties.
Furthermore, since the adhesive layer 12 is not provided in the portion of the first region 13 corresponding to the hanging hole 34, after the first region 13 and the second region 14 are separated, the adhesive layer 12 in the hanging hole 34 portion does not stick to the hand or the hook, resulting in excellent usability.

Although the present invention has been described above with reference to the embodiments, the present invention is not limited to these embodiments. The configurations and combinations thereof in the above embodiments are merely examples, and additions, omissions, substitutions, and other modifications of the configurations are possible within the scope of the present invention.
For example, in the above embodiment, an example is shown in which the adhesive layer 12 is not provided in the portion corresponding to the hanging hole 34 in the first region 13, but the adhesive layer 12 may be provided in the portion corresponding to the hanging hole 34 in the first region 13.
When the adhesive layer 12 is provided in the portion of the first region 13 corresponding to the hanging hole 34, it is preferable to provide an adhesion suppressing layer on the adhesive layer 12 in the portion of the first region 13 corresponding to the hanging hole 34. The adhesion suppressing layer can prevent the adhesive layer 12 in the portion of the hanging hole 34 from adhering to hands or hooks after the first region 13 and the second region 14 are separated.
The adhesion-suppressing layer is a so-called adhesive-killing layer that has the function of suppressing the adhesive force of the adhesive layer 12. The adhesion-suppressing layer can be formed by printing an adhesion suppressant, such as a printing ink such as an ultraviolet-curable ink or a solvent ink, or an overprint varnish, on the adhesive layer 12.
The adhesion inhibitor preferably contains a release agent. Examples of release agents that can be contained in the ultraviolet-curable ink include silicone compounds, alkyl pendant polymers, and condensation waxes.

A printed layer may be provided on one or both surfaces of the substrate 11, 41.
11 shows a modified example of the label 40. In this example, a label 40A includes a substrate 41A in place of the substrate 41, in which a front printed layer 44 is provided on a first layer 42 and a back printed layer 45 is provided on a second layer 43.
The back printed layer 45 is preferably printed with characters such as "Opened" or "OPEN" that indicate that the partition 36 is open. The front printed layer 44 is preferably printed with a pattern, characters, or the like that conceals the back printed layer 45. In this case, when the first layer 42 is peeled from the second layer 43, the back printed layer 45 becomes visible, making it easier for an operator to detect that the partition 36 is open.
The printing method is not particularly limited, and known printing methods such as gravure printing, flexographic printing, lithographic printing, and inkjet printing can be used.

Although the example in which the easy-to-tear portion that facilitates severing between the first region 13 and the second region 14 is composed of the perforated portion 16 and the cutout portions 17, 18 has been shown, the easy-to-tear portion is not limited to this. For example, the easy-to-tear portion may be composed of one or more of a perforated portion, a half-cut portion, a cutout portion, and a thin-walled portion. Furthermore, the shape of the cutout portions 17, 18 is not limited to the shape shown in the above embodiment. The thin-walled portion can be formed, for example, by creasing the label or the substrate.
The shape of the label of the present invention in plan view is not limited to that shown in the above embodiment, and may be, for example, any of the shapes shown in Figures 12(a) to 12(n).

The fluid contained in the second storage chamber S2 (another storage chamber) may be liquid or gas.
A plurality of other storage chambers may be formed. When a plurality of other storage chambers are formed, it is sufficient that at least one of the plurality of other storage chambers contains a fluid. A portion of the plurality of other storage chambers may contain a solid, rather than a fluid.
The first storage chamber S1 may contain either a fluid or a solid.
Examples of uses of the multi-chamber container containing fluid include medical use, food use, industrial use such as ink use, etc. From the viewpoint of the need to prevent misuse, medical use is preferred.
