Description

TECHNICAL FIELD The present invention relates to a label for a fluid-containing multiple-chamber container and a labeled fluid-containing multiple-chamber container.

Medicines such as peritoneal dialysate and infusion are generally prepared by blending a plurality of medicines. Some combinations of drugs cause changes over time when combined. In such cases, the multiple agents are mixed just prior to administration to the patient. A multi-chamber container having a plurality of storage chambers is used to store these multiple drugs. As a multi-chamber container, a container having a container body made of a flexible sheet is used. The container body has a plurality of storage chambers partitioned by partitions in which opposing flexible sheets are releasably joined to each other. At least a part of the drug contained in each of the plurality of storage chambers is liquid, and when a worker (medical worker, patient, etc.) presses the storage chamber containing such a drug by hand, the drug can be stored. The pressure inside the chamber increases, the partition opens, the plurality of storage chambers communicate, and the medicines stored in each storage chamber are mixed.

In order to avoid administering the unmixed drug to the patient, the hanging hole closure of a predetermined structure prevents the operator from hanging the multi-chamber container on a hanger or hook when the partition is not open. It has been proposed to attach a member to a hanging hole of a multi-chamber container (Patent Document 1).
In order to prompt the operator to open the partition, it has been proposed to attach a label to the container body that cannot be replaced within a predetermined label attachment frame when the partition is not opened (Patent Document 2). .

(Labeled multi-chamber container containing fluid)
A labeled multiple-chamber container 100 containing fluid includes a multiple-chamber container 1 containing fluid and a label 10 .
In the labeled double-chamber container 100 containing fluid, the double-chamber container 1 is arranged so that the second surfaces 3b face each other between the first edge portion 33 and the position corresponding to the first storage chamber S1. is folded into
The first area 13 of the label 10 is attached to the first surface 3 a of the container body 3 at the first edge 33 . Also, 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, that is, the position of the perforated portion 16, coincides with the position of the end of the fluid-filled double-chamber container 1 on the first edge portion 33 side in the first direction. there is
The position of the hole 15 of the label 10 and the position of the suspension hole 34 of the multi-chamber container 2 match.

The labeled fluid-filled double-chamber container 100 is configured such that the first region 13 of the label 10 is aligned with the fluid-filled double-chamber container 100 so that the position of the hole 15 of the label 10 and the position of the suspension hole 34 of the double-chamber container 2 are aligned. It is attached to the first surface 3a of the container 1, and the fluid-filled multi-chamber container 1 is folded so that the second surfaces 3b face each other between the first edge portion 33 and the position corresponding to the first storage chamber S1. After that, the second area 14 of the label 10 is attached to the second surface 3b of the container body 3, thereby manufacturing the container. After folding the multi-chamber container 1 containing fluid, the first region 13 of the label 10 may be attached to the first surface 3a.

The labeled fluid-filled multi-chamber container 100 is used as follows.
First, the second storage chamber S2 of the labeled fluid-filled multi-chamber container 100 is pressed. As a result, the pressure in the second storage chamber S2 increases, and the pressure causes the flexible sheet 31 and the flexible sheet 32 to separate at the partition section 36 (the partition section 36 is opened), and the liquid medicine L2 is released. The liquid medicine L1 and the liquid medicine L2 are mixed to form a mixed liquid medicine L3.
At this time, the first storage chamber S1 portion of the container body 3 swells more, thereby lifting the end of the container body 3 on the side of the first edge portion 33 and separating the first region 13 and the second region 14 of the label 10. A force is applied to the boundary of As a result, the perforated portion 16 is cut, and as shown in FIG. 6, the first region 13 and the second region 14 are separated.
Next, a hook of a stand or the like is inserted into the hanging hole 34 to hang the multi-chamber container 2 on the stand or the like.
After that, the mixed chemical solution L3 is discharged through the chemical solution discharge member 4. As shown in FIG. In the case of medical use, the discharged mixed drug solution L3 (infusion solution, etc.) is administered to the patient.

In this embodiment, the first region 13 and the second region 14 of the label 10 are separated when the partition 36 of the labeled fluid-filled double-chamber container 100 is opened, so that the partition 36 is opened. Workers can visually detect that In addition, since the separated first area 13 and second area 14 are not restored to their original states, erroneous use can be prevented.
Further, before the partition part 36 is opened, the fluid-filled multi-chamber container 1 is bent at a predetermined position, so that the suspension hole 34 is blocked and the hook cannot be inserted into the suspension hole 34 . Therefore, the operator can be urged to open the partition 36, and the labeled fluid-containing multiple-chamber container 100 can be used with the partition 36 unopened (for example, only the medicinal solution L2 is administered to the patient). ) can be prevented.
In addition, since the label 10 only needs to be attached to the fluid-filled multiple-chamber container 1, it can be easily set to the fluid-filled multiple-chamber container 1 compared to the hanging hole closing member described in Patent Document 1. In addition, since the label 10 is thinner than the hanging hole closing member described in Patent Document 1, the fluid-filled multi-chamber container 1 in which the label 10 is set is easy to stack and is excellent in storability.
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 of the hanging hole 34 portion is removed by hand. It does not stick to the tape or the hook, making it easy to use. Since the strength of the adhesive layer 12 is weak, the hook can be inserted even if the adhesive layer 12 is present in the hanging hole 34 portion.

<Second embodiment>
FIG. 7 is a schematic plan view of the label 40 according to the second embodiment. FIG. 8 is a schematic cross-sectional view at position VIII-VIII in FIG.
In addition, below, the same code|symbol is attached|subjected to the component corresponding to the above-mentioned component, and the detailed description is abbreviate|omitted.

A label 40 according to this embodiment includes a base material 41 and an adhesive layer 12 . The base material 41 is a multi-layer base material in which the first layer 42 and the second layer 43 are adhered (hereinafter also referred to as "pseudo-adhesion") so that they can be peeled off and cannot be re-attached after peeling. The adhesive layer 12 is provided on one surface of the base material 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-filled multi-chamber container 1 in the same manner as the label 10 of the first embodiment.
The label 40 is the same as the label 10 of the first embodiment except that the base material 41 is provided instead of the base material 11 . The holes 15 are not provided in the base material 41 .

As the first layer 42, the same material as the base material 11 can be used.
The thickness of the first layer 42 is preferably 5-400 μm, more preferably 20-300 μm. If the thickness of the first layer 42 is at least the lower limit value of the above range, the strength is high. The layer 42 cannot be ruptured and cannot be inserted. If the thickness of the first layer 42 is equal to or less than the upper limit of the above range, the stackability is good.

As the second layer 43, a soft thermoplastic resin layer is preferable. If the second layer 43 is composed of a soft thermoplastic resin, it is possible to obtain a pseudo-bonded state regardless of the material of the first layer 42 . Further, if the second layer 43 is made of a soft thermoplastic resin, when a hook is inserted into the hanging hole 34 after the first layer 42 is peeled off from the second layer 43, the second layer 43 covering the hanging hole 34 will be removed. break easily.
Soft thermoplastic resins include polyolefins such as polyethylene, polypropylene, and polybutene, polyvinyl chloride, polyvinylidene chloride, and polyesters.
The thickness of the second layer 43 is preferably 1-50 μm, more preferably 5-30 μm. If the thickness of the second layer 43 is equal to or greater than the lower limit of the range, the pseudo-adhesion stability is good. If 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 break when a hook is inserted into the hanging hole 34 after the first layer 42 is peeled off.

The adhesive strength between the first layer 42 and the second layer 43 is preferably 100-3000 mN/25 mm, more preferably 200-2000 mN/25 mm.
The adhesive strength between the first layer 42 and the second layer 43 is generally 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 the first region 13 is to be peeled off, the first layer 42 and the second layer 43 are peeled off before the adhesive layer 12 and the first surface 3a of the container body 3 are peeled off. .

A manufacturing method of the label 40 is not particularly limited, and may be the same as a known label manufacturing method. For example, the substrate 41 is obtained by coating one surface of the first layer 42 with a soft thermoplastic resin to form the second layer 43, and the surface of the substrate 41 on the side of the second layer 43 and the release sheet 20 is coated with an adhesive to form an adhesive layer 12, the base material 41 and the release sheet 20 are attached via the adhesive layer 12, and the obtained laminate is perforated, The label 40 can be manufactured by performing processes such as punching and half-cutting.

A labeled multi-chamber fluid-filled container having a label 40 attached to the fluid-filled multi-chamber container 1 is used as follows.
First, the second storage chamber S2 of the labeled multi-chamber container containing fluid is pressed. As a result, as in the first embodiment, the partition part 36 is opened and the first area 13 and the second area 14 of the label 40 are separated.
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 with the base material 41 . Hooks cannot be inserted in this state. Therefore, the first layer 42 of the base material 41 is separated from the second layer 43 . After the first layer 42 is peeled off, as shown in FIG. 10, the hanging holes 34 are covered only with the second layer 43 . The second layer 43 is easily torn by inserting a hook. Therefore, the multiple-chamber container 2 can be hung on a stand or the like by inserting a hook into the hanging hole 34 . After hanging the multi-chamber container 2 on a stand or the like, the mixed chemical liquid L3 is discharged from the chemical liquid discharging member 4 via the chemical liquid discharging member 4 .

In this embodiment, the first region 13 and the second region 14 of the label 40 are separated when the partition 36 of the labeled double-chamber container containing a fluid is opened, so that the partition 36 is opened. Workers can visually detect that they are In addition, since the separated first area 13 and second area 14 are not restored to their original states, erroneous use can be prevented.
Further, before the partition part 36 is opened, the fluid-filled multi-chamber container 1 is bent at a predetermined position, so that the suspension hole 34 is blocked and the hook cannot be inserted into the suspension hole 34 . Furthermore, even after the first region 13 and the second region 14 are separated, hooks cannot be inserted into the hanging holes 34 before the first layer 42 of the base material 41 is peeled off from the second layer 43 . Therefore, the operator can be urged to open the partition 36, and the labeled multiple-chamber container containing the fluid can be used with the partition 36 unopened (for example, only the drug solution L2 is administered to the patient). can be prevented.
Moreover, since the label 40 only needs to be attached to the fluid-filled multiple-chamber container 1, it is easier to set the fluid-filled multiple-chamber container 1 than the hanging hole closing member described in Patent Document 1. Further, since the label 40 is thinner than the hanging hole closing member described in Patent Document 1, the fluid-filled multi-chamber container 1 with the label 40 set thereon is easy to stack and is excellent in storability.
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 of the hanging hole 34 portion is removed by hand. It does not stick to the tape or the hook, making it easy to use.

Although the present invention has been described by showing embodiments, the present invention is not limited to these embodiments. Each configuration and combination thereof in the above-described embodiment are examples, and addition, omission, replacement, and other modifications of the configuration are possible without departing from the scope of the present invention.
For example, in the above-described embodiment, the adhesive layer 12 is not provided in the portion corresponding to the through hole 34 of the first region 13, but the adhesive layer 12 is not provided in the portion corresponding to the through hole 34 of the first region 13. may be provided.
When the adhesive layer 12 is provided in the portion corresponding to the hanging hole 34 of the first region 13, the adhesion suppressing layer is provided on the adhesive layer 12 in the portion corresponding to the hanging hole 34 of the first region 13. is preferred. After the first region 13 and the second region 14 are separated, the adhesion suppressing layer can prevent the adhesion layer 12 in the suspension hole 34 from sticking to hands or hooks.
The adhesion suppressing layer is a so-called paste-killing layer that has a function of suppressing the adhesive force of the adhesive layer 12 . The adhesion suppressing layer can be formed by printing an adhesion suppressing agent such as printing ink such as ultraviolet curable ink or solvent ink or overprint varnish on the adhesive layer 12 .
The adhesion inhibitor preferably contains a release agent. Release agents that can be contained in the UV-curable ink include silicone compounds, alkyl pendant polymers, condensed waxes, and the like.

A printing layer may be provided on one side or both sides of the substrates 11 and 41 .
FIG. 11 shows a modification of the label 40. As shown in FIG. Instead of the base material 41, the label 40A of this example includes a base material 41A having a front printed layer 44 provided on the first layer 42 and a back printed layer 45 provided on the second layer 43. FIG.
The back print layer 45 is preferably printed with characters indicating that the partition section 36 is open, such as "opened" or "OPEN". Moreover, it is preferable that the front printed layer 44 is printed with a pattern, characters, or the like that hides the back printed layer 45 . In this case, when the first layer 42 is peeled off from the second layer 43, the back printed layer 45 becomes visible, and the operator can easily detect that the partition section 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 applied.

Although the easy-to-cut portion that facilitates cutting between the first region 13 and the second region 14 has been shown as an example composed of the perforated portion 16 and the notch portions 17 and 18, the easy-to-cut portion is limited to this. not. For example, it may consist of one or more of a perforated portion, a half-cut portion, a notch portion and a thin portion. Moreover, the shape of the cutouts 17 and 18 is not limited to the shape shown in the above embodiment. The thin portion can be formed, for example, by a method of crimping the label or base material.
