FIG. 1 shows a bottom gusset-type pouch container 1 filled with a medical liquid such as liquid food, infusion, enteral nutrition, blood, or the like. As shown in the figure, the pouch container 1 includes a container main body 10 formed in a bag shape by a flexible sheet, and a spout member 20 that is attached to the container main body 10 for pouring the contents. It has. When the pouch container 1 is filled and packaged with the contents, as shown in FIG. 2, a pouch container package P1 with an expanded bottom gusset portion is completed and becomes self-supporting.

  The flexible sheet forming the container body 10 is usually composed of a single-layer or multiple-layer resin film, and a multilayer sheet having a base film layer and a sealant layer that imparts heat sealability. When a high gas barrier property is required, it is preferable to provide a gas barrier layer between the base film layer and the sealant layer.

  The film constituting the base film layer is composed of polyester such as polyethylene terephthalate, polyolefin such as polyethylene and polypropylene, polyamide such as nylon-6 and nylon-66, and ethylene-vinyl alcohol copolymer (EVOH). One or two or more layers of stretched or unstretched films can be exemplified.

  As the film constituting the sealant layer, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP) , Biaxially stretched nylon (ON), ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. A stretched or unstretched film having one layer or two or more layers can be exemplified.

  As the gas barrier layer, a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC), an ethylene-vinyl alcohol copolymer (EVOH), or an arbitrary synthetic resin film (for example, a base film layer) And a film obtained by evaporating (or sputtering) an inorganic oxide such as aluminum, aluminum oxide, or silica.

  The flexible sheet is provided with a printed layer so as to display precautions for use, which will be described later. Moreover, it is preferable to provide a scale for measuring the amount of the medical liquid. In addition to scales, items such as trade names, illustrations, and raw materials may be further provided.

  As shown in the figure, the container main body 10 is folded inward from the lower end portions of the pair of exterior sheets 11 formed of the flexible sheet that forms the body portion, and forms the bottom gusset portion. The bottom gusset sheet 12 is made of the flexible sheet, and the inner periphery of the folded bottom gusset sheet 12 is heat-sealed to the lower inner surface of the exterior sheet 11 and both side edges of the inner surface of the exterior sheet 11. Are formed into a bag shape by heat-sealing each other. Hereinafter, the heat seal portion between the exterior sheet 11 and the bottom gusset sheet 12 is referred to as a “bottom seal portion”, and the heat seal portion between the peripheral portions of the pair of exterior sheets is referred to as a “perimeter seal portion”. In addition, the area | region where the shaded display part in FIG. 1 is heat-sealed is shown.

  The exterior sheets 11 and 11 have a substantially pentagonal shape having an inclined edge SE at a part of the upper edge, and the spout member 20 is attached to the inclined edges SE of both the exterior sheets 11 and 11.

  On both side edges of the bottom gusset sheet 12, as shown in FIG. 1, notched portions 12 a that coincide with each other in a folded state are formed in a circular arc shape, and as shown in FIG. 3, Point seal portions PS in which the lower end portions on both side edges of the exterior sheets 11 and 11 are partially heat-sealed are formed via the cutout portions 12a, whereby the lower portions on both side edges of the bottom gusset portion are partially formed. Are joined together.

  As shown in FIGS. 4A to 4C, the spout member 20 covers a mouth body 21 in which a spout is formed by twisting off the tip 21 a and covers the mouth body 21. A cover 22 to be mounted and a mounting portion 23 having a boat shape or an elliptical shape in cross section, which are connected to the mouth body 21, are sandwiched between the inclined edges SE of the exterior sheets 11 and 11. In this state, the exterior sheets 11 and 11 are heat sealed. In addition, the spout member 20 rotates the cover 22 so that the tip end portion 21a of the mouth body 21 is twisted away from the mouth body 21, and the tube is connected to the mouth body 21 in which the spout is formed. Can be done. In addition, the spout member 20 is not limited to this, For example, the structure provided with the lid | screw screwed by the opening part main body may be sufficient.

  In this pouch container 1, the part between the upper end UE and the point seal part PS on both side edges of the bottom gusset part is not joined to each other, and the other side edge (the side on which the inclined edge SE is not formed). This unjoined part at the edge) can be used as the suspension HP. Specifically, as shown in FIGS. 5 (a) and 5 (b), a hook HK or the like of a suspension stand is inserted into the suspension part HP of the pouch container packaging body P1, and the hook as shown in FIG. The pouch container package P1 can be suspended by hooking the point seal part PS on HK or the like. At this time, since the pouch container 1 is of the bottom gusset type, the outer surface (that is, the bottom portion) of the bottom gusset sheet 12 constituting the bottom gusset portion functions as a guide for guiding the hook HK to the suspended portion HP. Therefore, in order to exhibit a guide function that facilitates insertion according to the shape of the suspension member such as the hook HK, the shape of the bottom seal portion in the bottom gusset portion may be asymmetric on both sides as shown in FIG.

  Further, in consideration of the workability of insertion of the suspension member such as the hook HK into the suspension portion HP, the length of the non-joint portion between the upper end UE and the point seal portion PS at both side edges of the bottom gusset portion is increased. Moreover, it is preferable to increase the folding length of the bottom gusset sheet 12. It is also preferable to form the point seal part PS at the lower end position of the bottom gusset sheet 12. Or you may have these together. In consideration of the suspension stability of the pouch container, as shown in FIGS. 8A and 8B, the point seal portion PS has an edge that follows the shape of the suspension member such as the hook HK. The shape is desirable because the suspended state is more stable.

  When the pouch container package P1 filled with the medical solution as the contents is suspended and administered to a person, the cover 22 of the spout member 20 is previously removed before the pouch container package P1 is suspended. It is desirable to disconnect and connect the tube C.

  As shown in FIG. 1, the exterior sheet 11 constituting the container body 10 has a “display indicating a suspended position”, a “display indicating a suspended use”, and a “display indicating a suspended state”, respectively. It has been subjected. As the “display indicating the suspended position”, for example, a colored display portion DP1 colored in an area indicated by an oblique line that becomes the suspended portion HP and an arrow display portion DP2 pointing to the suspended portion HP are displayed as “display indicating suspended use”. For example, the explanation display part DP3 such as “Please pass the hook along this arrow from the inside” or the like indicates the suspended state of the pouch container package P1 as the “indication indicating the suspended state”, for example. An illustration display unit DP4 may be mentioned.

  As described above, the pouch container 1 has a display portion indicating that the portion between the upper end UE and the point seal portion PS at the side edge of the bottom gusset portion is a suspended portion HP into which a suspended member can be inserted. Therefore, the user who handles the pouch container package P1 in which the medical solution is filled and packaged in the pouch container 1 is hung in a portion between the upper end UE and the point seal part PS at the side edge of the bottom gusset part. It can be easily recognized that it can be suspended through a hook or the like of the lower stand.

  Further, in the state where the pouch container package P1 is suspended, the hook HK of the suspension stand inserted into the suspension lower part HP is sandwiched between the side edges of the bottom seal part as shown in FIG. Since the suspended state is stable and the pouch container package P1 is less likely to swing, once the orientation of the pouch container package P1 is adjusted, the orientation does not easily change and is displayed on the pouch container package P1. There is an effect that it is easy to see the displayed scales. In this way, the pouch container / packaging body P1 can be used for medical purposes such as liquid foods, infusions, enteral nutrients, blood, etc. It can use suitably for the medical use which uses a liquid agent as the content.

  In addition, unlike the conventional suspendable pouch container, the pouch container 1 does not have a suspending hole formed in the container main body. There is also an effect that the waste disposal of the punched waste becomes easy.

  In addition, the pouch container 1 is provided with a spout member 20 attached to the inclined edge SE of the substantially pentagonal exterior sheet 11, 11 having an inclined edge SE at a part of the upper edge, and the substantially pentagonal exterior sheet 11. , 11 is formed in the vicinity of the other lower end corner, so that the spout member 20 is positioned at the lowest position in the state where the pouch container package P1 is suspended as shown in FIG. As a result, the medical liquid can be surely dispensed.

  The above-described pouch container 1 is provided with all three types of indications: “indication indicating suspension position”, “indication indicating suspension use”, and “indication indicating suspension state”. It is not limited to this, and it is sufficient that at least one type of display is provided, and a plurality of types of display may be combined.

  Moreover, although the display part which shows that it is suspension part HP which can insert a suspension member is provided in the exterior sheet | seat 11 in the pouch container 1 mentioned above, it is not limited to this, A bottom gusset sheet | seat 12 may be provided with a display unit. Thus, if the display part is provided in the bottom gusset sheet 12, the exterior sheet 11 can be used to the maximum extent as a display area for displaying various information. Specifically, as shown in FIG. 9A, display portions such as an arrow display portion DP2 and an explanation display portion DP3 are provided on the bottom seal portion of the bottom gusset sheet 12 folded between the exterior sheets 11 and 11. Also good. In particular, considering the visibility of the display, as shown in FIG. 5B, display portions such as an arrow display portion DP2 and an explanation display portion DP3 are provided in an unsealed region that becomes the bottom surface of the bottom gusset sheet 12. Is preferred.

  In addition, it is preferable that an easy insertion means that facilitates insertion of the suspension member is provided in the suspension portion HP. In the pouch container 2 shown in FIG. 10, the notch 10a is formed in the suspension part HP in the side edge of a bottom seal part as an easy insertion means. As shown in FIG. 11, the pouch container package P2 in which the bottom gusset portion is widened by filling and packaging the medical solution in the pouch container 2 is greatly opened by the notch portion 10a, and a hook or the like is opened. It is easy to insert the suspension member, and it is possible to easily recognize that the suspension member can be used.

  As the easy insertion means, as described above, it is conceivable to reduce the rigidity of the suspended portion HP in addition to forming the notched portion 10a in the suspended portion HP at the side edge of the bottom seal portion. As a specific method for reducing the rigidity of the hanging part HP, for example, as shown in FIG. 12, the outer sheet 11 and the bottom gusset sheet 12 are partially formed in a region that becomes the hanging part HP in the bottom seal part. An unsealed portion 10b that is not heat-sealed is formed, a cut 10c extending in the lateral direction is formed in the suspended portion HP at the side edge of the bottom seal portion as shown in FIG. 13, or a bottom seal is formed as shown in FIG. Forming a ruled line 10d extending in the lateral direction on the suspension part HP at the side edge of the part. Further, instead of the push ruled line 10d, a half cut, perforated ruled line, or the like may be employed.

  Further, in the pouch containers 1 and 2 described above, only the spout member 20 is attached to the container main body 10, but, for example, as in the pouch container 3 shown in FIG. If attached to the right edge of the main body 10, it becomes possible to inject diluted water or the like into the container main body 10, and the medical liquid adhering in the container main body 10 is also washed away with the injected diluted water and administered. can do.

  Further, in the above-described pouch containers 1, 2, and 3, the spout member 20 is attached to the inclined edge SE of the container body 10, but the present invention is not limited to this, and the spout member 20 has a peripheral seal portion. It only has to be attached to. For example, like the pouch container 4 shown in FIG. 16, the spout member 20 may be attached to the center of the upper edge of the container body 10A in the width direction. In the case of this pouch container 4, both sides of the bottom gusset portion An unjoined portion between the upper end UE and the point seal portion PS at the edge can be used as the suspended portion HP. As shown in FIG. 17, when a pouch container package P4 filled with a medical solution is wrapped in this pouch container 4, the spout member 20 does not face directly downward, but is slightly inclined. Since most of the medical solution within 10A is poured out, there is no particular problem. It should be noted that the medical liquid that remains slightly in the container main body 10A and cannot be completely dispensed can be completely dispensed by slightly tilting the suspended pouch container 4.

  Moreover, in each embodiment mentioned above, although the medical pouch container filled with medical drugs, such as a liquid food, was demonstrated, it will not specifically limit if the content can be poured out in the suspended state. It is effective for various pouch containers used for various purposes.

  Moreover, in embodiment mentioned above, although the pouch container with which the spout member 20 was mounted | worn was demonstrated, it is not limited to this, For example, if a spout part exists, spout in the shape of a seal part, for example It goes without saying that the present invention can also be applied to a pouch container that is not equipped with a conventionally known spout member such as forming a portion.
