[0009] The liquid medicine container of the present invention will be described with reference to the embodiment shown in the drawings. As shown in Figs. 1 to 3, the liquid medicine container 1 of the present invention is a liquid medicine container 1 including a container body 10 in which a transparent liquid medicine 5 is stored. The container body 10 is transparent and includes a front part 11 to which a front side covering label 14 is attached, and a back part 12 facing the front part 11 with the liquid medicine 5 sandwiched therebetween. The back part 12 allows the back surface of the front part 11 to be seen from the back part 12 side, and the front part 11 includes a display print part 13 which is made of characters that can be read or a figure that can be recognized when viewed from the back part 12 side (characters here) and on which a display related to the liquid medicine 5 (a warning display related to the liquid medicine 5 here) is printed. The front side covering label 14 covers the display print part 13 and is attached to the front part 11 so as to make it difficult or impossible to see the display print part 13 from the front part 11 side, and the liquid medicine container 1 allows the content of the display related to the liquid medicine to be understood by viewing the display print part 13 from the back part 12 side.

[0010] In this embodiment, the container body 10 of the liquid medicine container 1 is a soft bag 10 including a first sheet portion 15 made of soft resin forming the front portion 11 and a second sheet portion 16 made of soft resin forming the back portion 12. The container body of the liquid medicine container is preferably a soft bag. In addition, it is preferable that the front portion 11 of the container body 10 can be directly printed.

[0011] More specifically, the container body (soft bag) 10 of this embodiment is formed into a predetermined outer shape by heat-sealing the periphery of a sheet material formed by molding a thermoplastic soft resin material into a cylindrical shape by inflation molding. Here, heat sealing is a process of fusing the resin by applying heat and pressure and then cooling and solidifying it. That is, as shown in Figs. 1 and 3, the container body (soft bag) 10 has a heat-sealed portion 17 formed on the periphery, and includes a first sheet portion 15 surrounded by the heat-sealed portion 17 on the front portion 11 side (formed on the inner side of the heat-sealed portion 17 in Fig. 1), and a second sheet portion 16 surrounded by the heat-sealed portion 17 on the back portion 12 side (formed on the inner side of the heat-sealed portion 17 in Fig. 3).

[0012] The container body of the drug solution container may be made by folding one flat sheet material in half and heat-sealing the peripheral portion, by laminating two flat sheet materials and heat-sealing the peripheral portion, by molding a thermoplastic soft resin material into a flat cylindrical shape by inflation molding, etc. In these cases, the portions that face each other with the drug solution in between are the front portion and the back portion.

[0013] Examples of materials for forming the container body 10 include various thermoplastic elastomers such as polyolefins, such as polyethylene (PE) and polypropylene (PP), polybutadiene, ethylene-vinyl acetate copolymer (EVA), vinyl chloride, olefin-based elastomers, and styrene-based elastomers, or any combinations of these (blend resins, polymer alloys, laminates, etc.). The resin materials used preferably have heat resistance and water resistance sufficient to withstand high-pressure steam sterilization (autoclave sterilization).

[0014] The material for forming the container body 10 preferably contains polyolefin. Particularly preferred materials for forming the container body (soft bag) 10 include soft resins made by blending polyethylene or polypropylene with styrene-based thermoplastic elastomers such as styrene-butadiene copolymers and styrene-ethylene-butylene-styrene block copolymers, or olefin-based thermoplastic elastomers such as ethylene-propylene copolymers, ethylene-butene copolymers, and propylene-α-olefin copolymers to make them soft. These materials are preferred because they are high in strength and flexibility, have high heat resistance (particularly heat resistance during sterilization) and water resistance, and are particularly excellent in processability, allowing for reduced manufacturing costs.

[0015] The container body 10 may be a single-layer structure (single layer body) made of the above-mentioned materials, or may be a multi-layer laminate in which multiple layers (particularly layers of different materials) are laminated for various purposes. In the case of a multi-layer laminate, multiple resin layers may be laminated. In the case of a multiple resin layer laminate, the advantages of each resin can be combined, for example, the impact resistance of the container body 10 can be improved and blocking resistance can be imparted. In addition, when a layer made of an oxide such as titanium oxide, aluminum oxide, or silicon oxide is formed, the gas barrier property can be improved and the transparency of the container body 10 can be maintained, and the visibility of the inside can be ensured. In addition, when the container body 10 is a multi-layer laminate, the material forming the inner surface portion is preferably the above-mentioned material.

[0016] The thickness of the sheet material constituting the container body 10 is appropriately determined depending on the layer structure and the characteristics of the material used (flexibility, strength, water vapor permeability, heat resistance, etc.), and is not particularly limited, but is usually preferably about 100 to 500 μm, and more preferably about 200 to 360 μm.

[0017] Further, a port member 18 for discharging (removing) the medicinal liquid 5 stored in the container body 10 to the outside is attached to the container body 10. In this embodiment, the port member 18 is directly attached liquid-tightly to the container body 10 by heat fusion, ultrasonic fusion, high-frequency fusion, or the like. Note that the container body (soft bag) 10 may be provided at its periphery (heat-sealed portion 17) with a hole (hanging portion) 19 for hanging the medicinal liquid container 1 from a hanger or the like.

[0018] The rear surface of the front surface 11 of the container body 10 is visible from the rear surface 12 side. The front surface 11 of the container body 10 (the side shown in Figs. 1 and 2) is provided with a display print section (warning display print section) 13, which is made up of letters or figures that can be read when viewed from the rear surface 12 side (in this embodiment, letters and figures shown as "Caution") and on which a display (warning display) related to the medicinal liquid 5 is printed. In such a display print section, letters and figures that can be read when viewed from the rear surface side of the container body may be written side by side, or a display different from the letters and figures (for example, the name and amount of the medicinal liquid) may be written side by side. The display printed portion 13 can be provided by a known printing method (e.g., letterpress printing, intaglio printing, lithography, inkjet printing, etc.), but it is preferable that the method is one that is unlikely to peel off from the container body 10 (first sheet portion 15 and front portion 11) and does not impede the attachment of the front side covering label 14 described below to the container body 10 (particularly the portion where the display printed portion 13 is provided). In particular, the display printed portion 13 in this embodiment is preferably provided by letterpress printing.

[0019] It is preferable that the display printed section 13 has a display (particularly, a warning display) regarding the liquid medicine including characters that are inverted when viewed from the front side 11 side. Specifically, in this embodiment, as shown in Fig. 2, characters that are inverted left and right when viewed from the front side 11 side (indicated by the characters "Caution" in a left-right inverted state in Fig. 2) are printed on the front side 11 of the container body 10. The inversion state of the characters (or figures) may be appropriately determined in consideration of the state in which the display printed section is viewed from the rear side (in other words, the state in which it is desired to be able to read or recognize the characters or figures in a normal state from the rear side), and for example, in addition to a left-right inverted state, a top-down inverted state may also be used.

[0020] The indications on the printed display section 13 regarding the medicinal liquid preferably indicate precautions to be taken when handling the medicinal liquid 5 stored in the medicinal liquid container 1. This allows the precautions to be confirmed from the rear surface section 12 side. Furthermore, the indications on the printed display section 13 regarding the medicinal liquid (e.g., local anesthetic) 5 are preferably related to the administration form of the medicinal liquid. For example, when the medicinal liquid 5 is a local anesthetic for epidural administration, an indication (particularly a warning indication) regarding the administration form of the medicinal liquid may be a text indication such as "No intravenous injection" or "No intravenous injection" that indicates that the medicinal liquid should not be administered into a blood vessel (vein). This indication can be confirmed (visually recognized) from the rear surface section 12 side of the medicinal liquid container 1.

[0021] In addition, rapid administration of some medicinal fluids is prohibited (e.g., high-concentration potassium preparations, high-concentration lidocaine preparations, antiarrhythmic drugs, vasopressors, and antibiotics), and a possible warning label for such medicinal fluids would be "rapid administration prohibited." As for labeling (especially warning labeling) for medicinal liquids, it is effective to label them with regard to the dosage form, specifically, to indicate the dosage form that is to be prohibited.

[0022] In addition to the above-mentioned drugs, the medicinal liquid 5 stored in the container body 10 may be, for example, electrolyte liquid (electrolyte correction liquid, electrolyte replenishment liquid), extracellular fluid replacement liquid, TPN preparations, amino acid preparations, fat emulsions, protein preparations, antibody preparations, hyaluronic acid, antibacterial drugs, antiviral drugs, vaccines, antitumor drugs, immunosuppressants, steroid drugs, anti-inflammatory drugs, antirheumatic drugs, arthritis treatment drugs, antihistamines, antiallergy drugs, diabetes treatment drugs, hormone drugs such as growth hormone, bone calcium metabolism drugs, vitamins, blood preparations, hematopoietic drugs, antithrombotic drugs, antihyperlipidemic drugs, antiarrhythmic drugs, These include vasodilators, prostaglandins, calcium antagonists, ACE inhibitors, β-blockers, antihypertensives, diuretics, xanthine derivatives, β-agonists, antiasthmatics, antitussives, expectorants, anticholinergics, antidiarrheals, stomachic digestives, antiulcer drugs, laxatives, hypnotics, sedatives, antipyretics, cold medicines, antiepileptics, antipsychotics, antidepressants, anxiolytics, central nervous system stimulants, parasympathetics, sympathetics, antiemetics, central stimulants, antiparkinsonian drugs, muscle relaxants, antispasmodics, anesthetics, antipruritics, antimigraine drugs, oligonucleotides, genetic drugs, etc. Also, as for the labeling (warning labeling) for the medicinal liquid, those corresponding to the drugs are used. In addition, the chemical solution 5 is transparent, but the transparency referred to here means a degree of transparency that does not interfere with the visibility of the display printed portion 13 from the back portion 12 side (reading the letters or recognizing the figures shown on the display printed portion 13).

[0023] A front covering label 14 is attached to the front part 11 of the container body 10, covering the display print part 13 and making it difficult or impossible to see the display print part 13 from the front part 11 side. Specifically, as shown in FIG. 1, the front covering label 14 has an outer shape capable of covering the entire display print part 13, and is attached to the front part 11 so as to cover the entire display print part 13. The front covering label 14 is preferably opaque to such an extent that it makes it difficult or impossible to see the display print part 13 from the front part 11 side, and such opacity can be achieved, for example, by making the front covering label 14 a paper label. This prevents the display print part 13 (especially characters in a left-right inverted state or characters in a top-down inverted state) from being seen from the front part 11 side, and prevents misunderstandings and confusion regarding the handling of the liquid medicine.

[0024] The front side covering label 14 is preferably such that the characters or figures (here, characters) shown in the display print section 13 are displayed on the surface (surface on the front part 11 side) 20 of the front side covering label 14 so as to be readable or recognizable from the front part 11 side in a normal state. In this embodiment, the surface 20 of the front side covering label 14 displays a display (indicated as "Caution" in FIG. 1) that is readable from the front part 11 side in a normal state and has the same content as the display (warning display) regarding the medicinal liquid displayed in the display print section 13 (Caution display 21). This allows the same matter (warning display) to be recognized from both the front part 11 side and the back part 12 side of the medicinal liquid container 1. Note that the front side covering label 14 may display a display (for example, the name and amount of the medicinal liquid, etc.) different from the characters or figures displayed on the display print section 13, and in this embodiment, the drug name display 22 and the content display 23 are displayed side by side.

[0025] In addition, in the liquid medicine container 1 of this embodiment, the display printed part 13 has a display related to the liquid medicine printed in a dark color (e.g., black), and the back surface (surface on the rear surface 12 side) 24 of the front side covering label 14 is a light color (e.g., white). This makes it possible to more clearly read or recognize the characters or figures shown on the display printed part 13 from the rear surface 12 side in a normal state. That is, when the display printed part 13 is viewed from the rear surface 12 side, the back surface 24 (light color) of the front side covering label 14 becomes the background, improving the visibility of the display (dark color) related to the liquid medicine. Note that, by making the front side covering label 14 a paper label, the back surface 24 of the front side covering label 14 can be easily made a light color. Contrary to this embodiment, it is also possible to print in color on the display-printed portion other than the portion (characters or figures) showing the display related to the liquid medicine (in other words, print with characters or figures cut out), and make the characters or figures legible or recognizable from the rear side in a normal state by looking through the rear surface of the front covering label from the rear side. Specifically, the display-printed portion is formed by a colored portion with characters or figures cut out, and the rear surface 24 of the front covering label 14 is visible in the cut-out characters or figures, so that it is possible to recognize the characters or figures in the color of the rear surface 24 of the front covering label 14.

[0026] Furthermore, the liquid medicine container 1 of this embodiment does not have anything that obstructs the visibility of the printed indicator 13 from the rear surface 12 side. That is, the rear surface 12 of the container body 10 of the liquid medicine container 1 does not have a printed part or a label. This improves the visibility of the printed indicator 13 from the rear surface 12 side, and also makes it easier to check the state of the liquid medicine 5 from the rear surface 12 side, for example, whether or not foreign matter has been mixed into the liquid medicine 5.

[0027] As a means for understanding the contents of the indication regarding the liquid medicine from the rear side of the liquid medicine container, it is possible to print the indication on the rear side of the front side covering label (the surface attached to the container body). However, when printing on the rear side of the front side covering label, the adhesion of the front side covering label may decrease, and the front side covering label may peel off. In addition, there is a problem that foreign matter may adhere when printing on the rear side of the front side covering label, which requires the effort of checking whether or not such foreign matter is attached. Therefore, it is preferable not to print the indication or other indications on the rear side of the front side covering label. In particular, it is preferable that the rear side of the front side covering label does not have any printing.

[0028] Next, another embodiment of the liquid medicine container of the present invention will be described with reference to the examples shown in the drawings. In the following description, the description of the configurations that are substantially the same as those of the liquid medicine container 1 described above will be omitted, or the corresponding names and symbols will be used and detailed description will be omitted.

[0029] The liquid medicine container 3 shown in Figs. 4 to 6 is a pre-filled syringe, and the container body 30 is a transparent barrel 30 for a syringe.

[0030] Specifically, the medicinal liquid container (prefilled syringe) 3 of this embodiment includes a transparent barrel for a syringe 30 containing the medicinal liquid 5, a gasket 31 slidably contained within the transparent barrel for a syringe 30, and a plunger 32 for moving the gasket.

[0031] The transparent barrel for a syringe 30 is a substantially cylindrical member capable of liquid-tightly and slidably housing the gasket 31. A flange is provided at the rear end of the transparent barrel for a syringe 30. Although not shown, a small-diameter nozzle portion is provided at the tip of the transparent barrel for a syringe 30, and the medicinal liquid 5 housed in the transparent barrel for a syringe 30 can be discharged (taken out) from the nozzle portion.

[0032] As a material for forming the transparent barrel 30 for a syringe, transparent glass or resin material can be used, but it is preferable to use a resin material, and examples of such resin materials include various resin materials such as polypropylene, polyethylene, polystyrene, polyamide, polycarbonate, polyvinyl chloride, poly-(4-methylpentene-1), acrylic resin, acrylonitrile-butadiene-styrene copolymer, polyester such as polyethylene terephthalate, cyclic olefin polymer, and cyclic olefin copolymer. Among them, resin materials such as polypropylene, cyclic olefin polymer, and cyclic olefin copolymer are preferable because they are easy to mold, have excellent transparency, have little effect on the drug solution, and are heat resistant.

[0033] The gasket 31 is made of elastic rubber or synthetic resin. The gasket 31 is housed in the transparent barrel for a syringe 30, and its outer surface is in liquid-tight contact with the inner surface of the transparent barrel for a syringe 30. In the transparent barrel for a syringe 30, the medicinal liquid 5 is housed in a space formed between the transparent barrel for a syringe 30 and the gasket 31.

[0034] The plunger 32 is made of a hard or semi-hard resin. The plunger 32 is integrated with the gasket 31 at its tip, and the gasket 31 moves together with the plunger 32. In the liquid medicine container (prefilled syringe) 3 of this embodiment, the plunger 32 is pressed in the axial direction of the transparent barrel 30 for a syringe, and the plunger 32 and the gasket 31 are moved toward the tip side of the prefilled syringe 3, so that the liquid medicine 5 can be discharged (taken out) from the tip (nozzle) of the transparent barrel 30 for a syringe.

[0035] In the container body (transparent barrel for syringe) 30 of the drug solution container (prefilled syringe) 3 of this embodiment, the front part 34 and the back part 35 are outer surface parts of the transparent barrel for syringe 30, and the part on the side where the front side covering label 37 is attached is the front part 34, and the part facing the front part 34 in a direction perpendicular to the axial direction of the transparent barrel for syringe 30 and facing each other with the drug solution 5 in between is the back part 35. That is, the part on the side shown in Figures 4 and 5 is the front part 34, and the part on the side shown in Figure 6 is the back part 35.

[0036] The front portion 34 of the medicinal liquid container (prefilled syringe) 3 is provided with a display printing portion (warning display printing portion) 36 which consists of letters that can be read or recognizable figures (in this embodiment, letters, shown as "Caution") when viewed from the rear portion 35 side, and on which a display (here, a warning display) regarding the medicinal liquid 5 is printed.

[0037] The display print section 36 is printed with display information regarding the liquid medicine, including characters that are inverted when viewed from the front side 34. Specifically, in this embodiment, as shown in Fig. 5, the front side 34 of the container body 30 is printed with characters that are upside down when viewed from the front side 34 (indicated by the characters "Caution" in an upside-down state in Fig. 5).

[0038] As the display on the display print unit 36, the display described above for the display print unit 13 can be suitably used. Note that, also in the prefilled syringe of this embodiment, as the display on the medicinal liquid (particularly, the warning display), it is effective to display the administration form, specifically, the administration form to be prohibited. Also, the indication regarding the medicinal liquid may be related to the administration form, specifically, an indication of the administration form. Some prefilled syringes are administered using a syringe pump, and in this case, a notice to that effect (specifically, "For use with syringe pump only") can be displayed as a warning. Also, depending on the medicinal liquid filled in the prefilled syringe, it is effective to display (warning) indications such as "For use with infusion only" or "Dilution required."

[0039] A front covering label 37 is affixed to the front part 34 of the container body (transparent barrel for syringe) 30, covering the display print part 36 and making the display print part 36 difficult or impossible to see from the front part 34 side. The front covering label 37 also displays on its surface 38 (the surface on the front part 34 side) the same characters (indicated as "Caution" in FIG. 4) as those displayed on the display print part 36, which are readable in normal conditions from the front part 34 side (Caution display 39). Furthermore, the front covering label 37 displays a drug name display 40 and a content amount display 41 side by side. In addition, it is preferable that the back surface 42 (the surface facing the rear portion 35) of the front side covering label 37 does not hinder the visibility of the display printed portion 36 from the rear portion 35 side. For example, if the display printed portion 36 has information regarding the chemical solution printed in a dark color (e.g., black), it is preferable that the back surface 42 of the front side covering label 37 is a light color (e.g., white).

[0040] The liquid medicine container (prefilled syringe) 3 of this embodiment does not have anything that obstructs the visibility of the display print part 36 and the liquid medicine 5 from the rear part 35 side. In other words, the rear part 35 of the liquid medicine container 3 does not have a print part or a label.

[0041] With such a liquid medicine container (prefilled syringe) 3, the same effect as that of the above-mentioned liquid medicine container 1 can be obtained. That is, the content of the indication (here, the warning indication) regarding the liquid medicine 5 can be grasped from the side opposite to the side on which the indication is printed (the rear surface part 35 side).

[0042] The display print part of the liquid medicine container (prefilled syringe) is not limited to the above-mentioned form, and may be, for example, a form such as that of the liquid medicine container (prefilled syringe) 3a shown in Figs. 7 to 9. Specifically, the display print part 36a of the liquid medicine container 3a has characters or figures (here, characters indicating "Caution") that are legible or recognizable in a normal state when the display print part 36a is viewed from the rear part 35 side (the state shown in Fig. 9) and the container body 30 is viewed in a standing state with the tip side facing up (a state rotated 90° counterclockwise from the state shown in Fig. 9). In this way, the form of the display print part of the liquid medicine container (prefilled syringe) can be appropriately set depending on the type and use mode of the liquid medicine container (prefilled syringe).

[0043] The liquid medicine container of the present invention is not limited to the above-mentioned embodiments (a liquid medicine container having a soft bag as the container body or a pre-filled syringe), but may be a liquid medicine container such as a vial or an ampule.
