[Industrial applications]

 The present invention relates to an improvement of an outer bag having a gas barrier property for storing and storing a plastic container in which a medical drug solution such as an infusion bag is sealed.

[0002]

[Prior art]

 Conventionally, glass containers have been used as containers for medical liquid medicines such as infusion solutions.However, glass containers have drawbacks such as heavy weight, risk of damage due to impact, bulky and inconvenient for transportation and storage. Recently, plastic containers made of polyethylene, polypropylene, polyvinyl chloride resin, etc. are often used instead of glass containers. These plastic containers, by themselves, are difficult to guarantee the high degree of gas barrier properties required to prevent alteration of chemical liquids such as glass bottles.Therefore, for certain chemical liquids, the plastic container has a gas barrier property prepared separately. The bag provided is used for outer packaging.

In FIG. 4, 10 is a plastic container (hereinafter, “infusion bag”) filled with a liquid medicine such as an infusion bag, and 40 is an outer bag having a gas barrier property for storing and storing the infusion bag 10. The outer bag 40 is made of a laminated film in which a gas barrier resin layer, a heat-fusible resin layer, etc. are laminated, and the left and right side edges b and c of the two laminated films and the bottom Each of the edges d is heat-sealed as an adhesive margin to form a bag, the infusion bag 10 is housed therein, and the top opening end a is sealed by heat-sealing similarly to the side edges. The package is completed (the inner space atmosphere of the bag 40 is subjected to treatment with an oxygen scavenger or replacement treatment with nitrogen gas or the like when sealing the top opening). The package in which the infusion bag 10 is enclosed in the outer bag 20 is vertically packed in a vertical cartoner or the like for transportation.

[0004]

[Problems to be solved by the device]

 The packaging work for accommodating and sealing the infusion bag 10 in the outer bag 40 is performed manually or by using an automatic loading machine. In either case, from the viewpoint of workability, the outer bag 40 is used. The bag used is a bag having a large size with a sufficient margin in the width direction for the infusion bag 10 to be stored. For this reason, the liquid transfusing bag 10 in the outer bag 40 is likely to move due to vibration during transportation such as transportation of the package packed in a vertical cartoner or the like, and other handling processes, and the outer bag 40 is rubbed against the inner surface of the outer bag 40 to cause the outer bag There is a problem in that the laminated film of the bag 40 and the gas barrier resin layer are flawed, and pinholes are generated to impair the gas barrier property. In addition, bending and deformation repeatedly occur in the corners (margins) 41, 41 on the left and right sides of the bottom of the outer bag 40 during the transportation process, and bending fatigue causes pinholes, impairing gas barrier properties. Become. The present invention has been made in order to solve the above-mentioned problems relating to the outer bag of the infusion bag.

[0005]

[Means for Solving the Problems]

 The present invention is an outer bag made of plastic having a gas barrier property for enclosing an infusion bag, in which the width between the inner left and right edges on the bottom side of the bag is the range in which the infusion bag can be stored toward the bottom of the bag. It is characterized by narrowing inside.

[0006]

[Action]

 The outer bag for infusion bag of the present invention has such a shape that the bottom side is narrowed toward the bottom side (and thus the opening cross-sectional area of the bag on the bottom side is also gradually reduced toward the bottom side). The infusion bag to be stored is stably held and restrained in the area where the bottom side is narrow in the outer bag 20. As a result, even if the infusion bag is transported vertically packed in a vertical cartoner or the like, the outer bag cannot be covered. The infusion bag inside the bag has less movement due to vibration and shaking, and the bending deformation of the corners on both sides of the bottom of the outer bag and the resulting fatigue deterioration of the film are avoided. Therefore, the generation of pinholes that impair the gas barrier properties of the outer bag is prevented.

Hereinafter, the present invention will be described with reference to the drawings illustrating an embodiment. The same members and the same parts in FIG. 4 are designated by the same reference numerals. As shown in FIG. 1, the outer bag 20 of the present invention is such that the width between the left and right side edges b and c (the inner width of the bag) on the bottom side is within a range in which the infusion bag 10 can be stored. The infusion bag 10 has a shape that narrows toward the bottom side, and the infusion bag 10 to be loaded therein is held and restrained in a region where the bottom portion of the outer bag 20 is narrow to provide a stable storage posture. . With respect to the shape of the bottom side of the outer bag 20, the width of the outer bag 20 narrows toward the bottom within the range in which the infusion bag 10 can be accommodated, because the infusion bag 10 is accommodated reasonably and the bottom portion (in the figure, it is suspended). This means that the hand portion 11) is seated on the bottom of the outer bag 20, and the infusion bag 10 is appropriately inclined and narrowed so that the infusion bag 10 can be held and restrained at the bottom. The shape of the region where the inner width on the bottom side of the outer bag 20 narrows toward the bottom (inner width slanted portion) is such that the inner edge lines 22 and 22 of the film bonding margin in that region are on the bottom in the bag manufacturing process. It is formed by heat-sealing the part so that it is oriented so as to be inclined once. The left and right corners 21 and 21 of the bottom of the outer bag 20 are reinforced by heat fusion unlike the hollow corners 41 and 41 of the conventional outer bag 40 shown in FIG. Deformation is unlikely to occur, and even if bending deformation is repeated, pinholes that impair gas barrier properties do not occur. The figure shows an example in which the inner edge lines 22 and 22 of the inner width slanted portion are substantially straight lines, but the invention is not limited to this, and a moderate curve is drawn and the inner width once decreases. It may have a shape.

The corners 21 and 21 on both the left and right sides of the bottom of the outer bag 20 do not necessarily have to remain as shown in FIG. 1, and the outer contour of the corner is rounded or the inner edge of the bonding margin is The shape may be such that corners are cut out in a direction substantially parallel to the line. FIG. 2 shows such an example, and shows a shape in which the left and right corners on the bottom side of the outer bag 20 are cut out substantially parallel to the inner edge lines 22, 22 of the adhesive margin. By adjusting the shape of the bottom of the outer bag 20 in this way, the contact and resistance between the box and the package when packing individual boxes such as vertical cartons can be reduced, making it possible to use tight individual boxes. Become. This not only has the effect of reducing the carrying volume, but also reduces the vibration and shaking of the package packed in the individual box. As a result, the friction between the outer bag 20 and the infusion bag 10 is reduced, and the occurrence of pinholes is prevented. Works well.

Further, the outer bag 20 of the present invention may have a shape in which the top opening end side is directed upward and widened, as shown in FIG. 3, whereby the infusion bag is automatically loaded. Easy to operate. The infusion bag 10 accommodated in the outer bag 20 is provided with a stable fixed posture with less movement due to vibration or the like on the bottom side, which is not different from that described with reference to FIGS. 1 and 2 above.

The material film of the outer bag 20 of the present invention does not need to be different from the conventional one. For example, the outer layer, the biaxially stretched nylon film having high strength (for example, 25 μm in thickness), the intermediate layer, An ethylene / vinyl alcohol copolymer resin layer (for example, 15 μm) having a gas barrier property, and a laminated film in which the inner layer is a linear low-density polyethylene film (for example, 40 μm) having heat fusion property may be used. . In addition, the bag-making process is the same as the normal bag-making process except that the shape of the bonding margin of the left and right side edges is set so that the inner width dimension on the bottom side becomes narrower toward the bottom side. The side edges b and c and the bottom edge d of the raw material film are heat-sealed by a conventional method, and the corner contour on the bottom side is adjusted as desired as shown in FIG. Loading of the infusion bag 10 into the outer bag 20 may be performed manually or automatically in accordance with a conventional method. Then, the margin of the top opening a should be provided above the mouth plug 12 of the infusion bag 10 with an appropriate allowance. The package is completed by heat-sealing the parts as an adhesion margin.

The material film of the outer bag 20 of the present invention is not limited to the above examples, and various laminated films having gas barrier properties can be appropriately used, and the shape of the bag is, of course, that shown in the figure. It is not limited.

[Effect of device]

 The outer bag of the present invention stably stores the infusion solution bag, and is less likely to cause pinholes due to friction with the infusion solution bag and bending fatigue of the corners on the bottom side during transportation and other handling processes, and has a gas barrier property. It is stably maintained, and therefore has an excellent effect of maintaining the quality of the drug solution in the infusion bag.
