2. Description of the Related Art Conventionally, when storing and preserving easily oxidizable drugs, etc., in order to avoid the influence of oxygen (air),
For example, as shown in FIG. 4, a medical bag 10 filled with a drug is sealed in a gas-barrier packaging bag 12 together with an oxygen absorber 14 and the like, and the sealed packaging bag is directly stored in a packaging box such as a cardboard box. It is customary. However, the hermetically sealed packaging bag has a problem in that pinholes are generated due to an impact during transportation, and the sealing property of the packaging bag may be impaired. Therefore, the original purpose of using the packaging bag of the barrier film cannot be achieved. there were. Therefore, as a countermeasure, instead of a sealed packaging bag, a medical bag is individually sealed in a thick and strong tray-shaped container made of a gas barrier material, and a plurality of tray-shaped Means have been proposed in which containers are packed in cardboard to avoid adverse effects such as destruction of gas barrier properties due to impact, vibration, and the like during transportation (see Japanese Patent Publication No. Hei 1-37954). It is also conceivable to use a thick film as a material for the sealed packaging bag in order to prevent the occurrence of pinholes.

[0003]

However, the means of individually packaging the above-mentioned tray-shaped containers increases the amount of expensive gas barrier material used, increases production costs, and increases the amount of waste after use. It is difficult to adopt. Further, it is difficult to adopt the method of thickening the film of the bag for hermetic packaging because the production cost becomes high as in the case of the tray-shaped container. Thus, while the inventors of the present application have been intensively studying the causes of pinholes, the following has been found. That is, the sealed packaging bag is usually transported in a packaging box such as cardboard, but the cardboard has a rough inner wall surface and high mechanical strength, so that the sealed packaging bag and the inner wall of the cardboard are subject to impact or vibration during transportation. It was found that the sealed packaging bags were rubbed against each other and damaged, and as a result, pinholes were easily generated. The present invention has been made in view of such circumstances, and an object of the present invention is to provide an assembly of sealed packaging bags as packaging means capable of preventing the generation of pinholes.

The present invention has been made to achieve such an object, and the present invention is configured as follows. A A package of sealed packaging bags in which a plurality of sealed packaging bags each having a content sealed in a gas barrier bag are accommodated in a packaging box, and a plurality of sealed packaging bags are provided in one or more plastic bags.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 1, reference numeral 16 denotes a cardboard as a packaging box, in which a number of sealed packaging bags 12 are accommodated. These sealed packaging bags 12 are housed in a cardboard 16 in a state of being put in a plastic bag 18. This prevents the inner wall surface of the cardboard 16 from directly rubbing against the sealed packaging bag 12 due to vibration or the like during transportation,
The occurrence of pinholes in the sealed packaging bag 12 is prevented. As shown in FIG. 4, the hermetically sealed packaging bag 12 is obtained by enclosing a medical bag 10 containing an oxidizable agent in a packaging bag made of a gas barrier film together with an oxygen scavenger 14 and the like. . Reference numeral 20 denotes a plug of the medical bag 10.

As shown in FIG. 1, these sealed packaging bags 12 are stacked and accommodated in a plurality of stages. In the same stage, adjacent sealed packaging bags 12 are arranged so as to approach each other. Above the boundary of the sealed packaging bag 12, the upper sealed packaging bag 12 is arranged so as to straddle. As a result, the gap between the sealed packaging bags 12 is reduced, the filling efficiency of the cardboard 16 is improved, and the movement of the sealed packaging bags 12 in the cardboard 16 during transportation is suppressed. Combined with the action of the plastic bag 18 for preventing the bag 12 from directly rubbing, there is an advantage that the generation of pinholes in the sealed packaging bag 12 can be prevented. It is not necessary that the center of the upper packaging bag 12 in the width direction of the upper packaging bag 12 is located directly above the boundary between the adjacent packaging bags 12, and the position where the sealing packaging bag is straddled is not necessarily required. It is also possible to bias to. In short, it is sufficient if there is no problem in stacking in a stable state.

The material of the plastic bag 18 is LL
Any material used for general packaging such as DPE and HDPE having a smooth surface can be suitably used. It should be noted that the material is not particularly limited, but a material having a good opening property of the bag is desirable from the viewpoint of improving the efficiency of the storing operation. The thickness of the plastic bag 18 is preferably about 15 to 80 μm in terms of handling. Note that the plastic bag 18 may be provided with a hand hole for facilitating removal.

In storing the sealed packaging bag 12 in the plastic bag 18, the plurality of sealed packaging bags 12 may be stored in the plastic bag 18 and then put together in the cardboard 16 together with the plastic bag 18. 1
The sealed packaging bag 12 may be accommodated in the plastic bag 18 after the container 8 is put in the cardboard 16. The number of plastic bags 18 used for one corrugated cardboard 16 is not limited to one, and a plurality of plastic bags 18 may be used, and the required number of sealed packaging bags 12 may be accommodated in each plastic bag 18.
In addition, the plastic bag 1 containing the sealed packaging bag 12
It is sufficient that the opening 8 is folded or rolled up without any particular sealing.

FIG. 2 shows another embodiment of the present invention. In the following, members that do not need to be changed are assigned the same reference numerals and description thereof is omitted. This embodiment is the same as the above embodiment in that a plurality of sealed packaging bags 12 are stacked and accommodated in a plastic bag 18 arranged in a cardboard 16 in a multi-stage manner, but adjacent sealed packaging bags 12 are partially overlapped. This embodiment is different from the above embodiment in that they are arranged in the inclined state. The gap between the sealed packaging bags 12 is reduced, the filling efficiency of the cardboard 16 is improved, and the movement in the cardboard 16 during transportation is suppressed. Therefore, as in the case of the above embodiment, the sealed packaging bag 1
There is an advantage that generation of pinholes can be prevented.

FIG. 3 shows another embodiment of the present invention, which is the same as the above embodiments except that the way of stacking the sealed packaging bags 12 is different. The sealed packaging bags 12 of each stage are arranged in one row in the vertical direction without shifting in the horizontal direction, and the gap between the sealed packaging bags 12 is slightly increased, and the filling rate tends to decrease. In addition, the effect of preventing the plastic bag 18 from generating pinholes in the sealed packaging bag 12 can be maintained. In each of the above embodiments, the sealed packaging bag 1
As shown in FIG. 4, the medical bag 10 in the plug 2 has only one plug 2 on one side.
In the case where there is a protrusion such as 0, the plugs 20 may be arranged so that the orientation of the plugs 20 is the same in the same stage, and the orientation is alternately changed in the upper and lower stages. There is an advantage that the stacked state of the sealed packaging bags 12 is further stabilized, and the effect of preventing displacement is increased. Although some embodiments of the present invention have been described above, the present invention is not limited to such embodiments at all, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention. It is.
