Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an assembly of hermetically sealed packaging bags capable of preventing the occurrence of pinholes, and in particular, a hermetically sealed packaging bag designed to prevent the individually packaged hermetically sealed packaging bags from directly contacting the inner surface of the packaging box. It concerns an aggregate.

[0002]

[Prior art]

 Conventionally, in the case of storing and preserving easily oxidizable drugs and the like, in order to avoid the influence of oxygen (air), for example, a medical bag 10 filled with a drug as shown in FIG. 4 is packaged in a gas barrier property. It is customary to seal the bag 12 together with the oxygen scavenger 14 and the like, and then directly store the sealed packaging bag in a packaging box such as a corrugated board. However, in the hermetically-sealed packaging bag, pinholes may be generated due to impact during transportation, and the hermeticity of the packaging bag may be impaired. Therefore, the original purpose of using the packaging film of barrier film cannot be achieved. There was a point. Therefore, as a countermeasure, instead of the hermetically-sealed packaging bag, a medical bag is individually packaged in a tray-like container that is thick and strong and made of gas barrier material. A means for avoiding the adverse effects such as the destruction of the gas barrier property due to the impact and vibration during transportation has been proposed (see Japanese Patent Publication No. 1-37954). In addition, it is conceivable to use a thick film as a material for the hermetically-sealed bag to prevent the occurrence of pinholes.

[0003]

[Problems to be solved by the device]

 However, it is difficult to use the above-mentioned means for individually packaging in a tray-like container because the amount of expensive gas barrier material used increases, the production cost increases, and the amount of waste after use increases. In addition, the method of thickening the film of the bag for hermetic packaging is difficult to use because the production cost becomes high as in the case of the tray-shaped container. Then, while the inventor of the present application continued to earnestly study the cause of the occurrence of the pinhole, the following was revealed. In other words, sealed packaging bags are usually transported in packaging boxes such as corrugated cardboard, but since corrugated cardboard has a rough inner wall surface and high mechanical strength, the sealed packaging bag and the inner wall of the corrugated board are subject to shock and vibration during transportation. We found that the sealed packaging bag was damaged by rubbing against each other, resulting in pinholes. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a stack of sealed packaging bags as a packaging means capable of preventing the generation of pinholes.

[0004]

[Means for Solving the Problems]

 The present invention has been made to achieve such an object, and the present invention is configured as follows. A A hermetically-sealed packaging bag in which a plurality of hermetically-sealed packaging bags in which the contents are enclosed in a gas-barrier bag is accommodated in one or more plastic bags, each of which is a plurality. A stack of hermetically sealed packaging bags, wherein the hermetically sealed packaging bags are accommodated in the packaging box in a state where the hermetically sealed packaging bags are accommodated so that the hermetically sealed packaging bags do not come into direct contact with the inner surface of the packaging box. B In the hermetically-sealed packaging bag assembly according to the item A, a plurality of the hermetically-sealed packaging bags are stacked and accommodated in the plastic bag in a packaging box, and the hermetically-sealed packaging bags are adjacent to each other in the same tier. A stack of hermetically sealed bags arranged in close contact with each other or close to each other, and in such a manner that the upper hermetically sealed packaging bags straddle each other at the boundary between the laterally adjacent hermetically sealed packaging bags. C In the aggregate of the hermetically sealed packaging bags according to the item A, the plurality of hermetically sealed packaging bags are housed in the packaging bag in a plurality of layers in the plastic bag, and the hermetically sealed packaging bags are adjacent to each other in the same layer. A stack of hermetically sealed packaging bags arranged in a partially overlapping manner.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 16 is a cardboard as a packaging box, which accommodates a large number of hermetically sealed packaging bags 12. Then, these hermetically sealed packaging bags 12 are accommodated in the corrugated cardboard 16 in a state of being enclosed in the plastic bag 18. This prevents the inner wall surface of the corrugated cardboard 16 from directly rubbing against the hermetically sealed packaging bag 12 due to vibration or the like during transportation, and prevents the occurrence of pinholes in the hermetically sealed packaging bag 12. As shown in FIG. 4, the hermetically sealed packaging bag 12 is obtained by encapsulating a medical bag 10 in which an easily oxidizable drug is enclosed together with a deoxidizer 14 in a packaging bag made of a gas barrier film. . Reference numeral 20 is a plug of the medical bag 10.

As shown in FIG. 1, these hermetically sealed packaging bags 12 are stacked and accommodated in a plurality of stages. However, in the same stage, adjacent hermetically sealed packaging bags 12 are arranged so that they are close to each other, and Above the border of the hermetically-sealed packaging bag 12, the upper hermetically-sealed packaging bag 12 is arranged so as to straddle. As a result, the gap between the hermetically-sealed packaging bags 12 is reduced, the efficiency of filling the corrugated cardboard 16 is improved, and the movement of the hermetically-sealed packaging bag 12 in the corrugated board 16 during transportation is suppressed. Combined with the action of the plastic bag 18 that prevents the bags 12 from directly rubbing against each other, there is an advantage that pinholes in the hermetically sealed packaging bag 12 can be prevented. The position where the hermetically sealed packaging bags are folded does not necessarily have to be the center in the width direction of the upper hermetically sealed packaging bags 12 just above the boundary between adjacent hermetically sealed packaging bags 12. It is also possible to bias it. In short, it should not interfere with stacking in a stable state.

As the material of the plastic bag 18, any material used for general packaging such as LLDPE and HDPE and having a smooth surface can be preferably used. It is not necessary to pay particular attention to the material, but from the viewpoint of improving the efficiency of storage work, it is desirable that the bag has good openability. 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 easy removal.

When housing the hermetically sealed packaging bag 12 in the plastic bag 18, a plurality of hermetically sealed packaging bags 12 may be housed in the plastic bag 18 and then placed in the corrugated ball 16 together with the plastic bag 18. Alternatively, the plastic bag 18 may be put in the cardboard box 16 in advance and then the sealed packaging bag 12 may be housed in the plastic bag 18. The number of plastic bags 18 used for one corrugated ball 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. Further, it is sufficient to fold or wrap the opening of the plastic bag 18 after accommodating the hermetically sealed packaging bag 12 without special sealing.

FIG. 2 shows another embodiment of the present invention. The members that do not need to be changed are given the same reference numerals and the description thereof will be omitted. This embodiment is similar to the above embodiment in that a plurality of hermetically sealed packaging bags 12 are stacked and housed in a plastic bag 18 arranged in a corrugated cardboard 16, but the adjacent hermetically sealed packaging bags 12 are partially separated from each other. It is different from the above embodiment in that they are arranged in a stacked state. The gap between the hermetically sealed packaging bags 12 is reduced, the efficiency of filling the cardboard 16 is improved, and the movement of the cardboard 16 during transportation is suppressed. Therefore, as in the case of the above-mentioned embodiment, there is an advantage that the pinhole generation of the hermetically sealed bag 12 can be prevented.

FIG. 3 shows another embodiment of the present invention, which is the same as the above-mentioned embodiments except that the stacking method of the hermetically sealed bags 12 is different. The sealed packaging bags 12 in each stage are arranged in one row in the vertical direction without being laterally displaced, and the gap between the sealed packaging bags 12 is slightly increased, and the filling rate tends to decrease. However, the effect of preventing the occurrence of pinholes in the sealed packaging bag 12 by the plastic bag 18 can be maintained. In each of the above embodiments, when the medical bag 10 in the hermetically sealed packaging bag 12 has a protrusion such as the spout 20 on only one side as shown in FIG. You may arrange so that the direction may become the same, and may arrange so that the direction may change by turns at the upper and lower stages. There is an advantage that the stacked state of the hermetically sealed packaging bags 12 becomes more stable, and the effect of preventing slippage increases. Although some embodiments of the present invention have been described above, the present invention is not limited to these embodiments and can be implemented in various modes without departing from the scope of the present invention. Of course.

[0011]

Since the present invention is configured as described above, it has the following effects. According to the aggregate of the hermetically sealed bags according to claim 1, since the hermetically sealed bags are accommodated in the packaging box while being accommodated in the plastic bags, the inner wall surface of the packaging box and the hermetically sealed bags are in direct contact with each other. Therefore, the sealed packaging bag and the inner wall surface of the packaging box do not rub against each other even when subjected to vibration or shock during transportation, so the sealed packaging bag is not damaged and pinholes can be prevented. As a result, the gas barrier property of the sealed packaging bag can be maintained. According to the aggregate of the hermetically sealed bags according to claim 2 or 3, the gap between the hermetically sealed bags becomes small, the filling efficiency of the hermetically sealed bags into the packaging box is improved, and the gap becomes small. Relative movement of the sealed packaging bag in the packaging box during transportation is suppressed, and in combination with the effect of housing the sealed packaging bag in the plastic bag, damage to the sealed packaging bag is less likely to occur and pinholes are prevented from occurring. The effect of is improved.
