Description

  The present invention relates to an integrated packaging bag that can accommodate and carry a plurality of medical liquid bags and a method for manufacturing the same, and an integrated package in which a plurality of medical liquid bags are stored in the integrated packaging bag and a method for manufacturing the same.

2. Description of the Related Art A medical drug solution bag (infusion bag) for storing a drug solution for infusion or the like is known to have a vertically long shape (that is, a shape that is long in the vertical direction (substantially vertical direction)) as shown in FIG. This medical liquid bag 30 is made of a resin film or the like, and its peripheral edge 31 is closed by heat sealing. And the port part 32 used as the entrance / exit of a chemical | medical solution is formed in one short side, and the other short side is the bottom 33.
Conventionally, such a medical drug solution bag 30 has been handled in a state of individual packaging put in an outer bag one by one. However, recently, from the viewpoint of ease of handling and the like, there are an increasing number of cases where a plurality of such packages are arranged and accommodated in one integrated packaging bag 40 having a grip portion 42 as shown in FIG. At this time, each medical liquid bag 30 is usually stored in a vertically long shape with the bottom 33 side facing down and the port portion 32 facing up.
In the present specification, the medical solution bag is “contained vertically” means that the substantially rectangular medical solution bag is vertically long when the holding portion of the integrated packaging bag is placed upward. The medical drug solution bag is “contained horizontally” in the case where the grasping portion of the integrated packaging bag is placed on the top, and the medical bag of approximately rectangular shape. The medical solution bag is stored upright so as to be long in the left-right direction (substantially horizontal direction). In both cases of “contained vertically” and “contained horizontally”, the medical solution bag is accommodated in a flat stack when the gripping portion of the integrated packaging bag is placed upward. It does not include the state.

The integrated packaging bag 40 shown in FIG. 6 is made of a film of polyethylene or the like, and when storing a plurality of medical drug solution bags 30 as shown in FIG. As shown in FIG. 4, the medical drug solution bags 30 to be accommodated are stacked in a flat shape, and are then slid in a substantially horizontal direction indicated by an arrow in the stacked state, at the opening of the integrated packaging bag 40. It accommodates from the certain bottom part 41, and the bottom part 41 is heat-sealed and sealed after that.
The integrated packaging bag 40 in which a plurality of medical drug bags 30 are stored in this way is further accommodated in a cardboard box so that the gripping portion 42 is up, that is, each medical drug bag 30 is vertically long and transported. Often done. Hereinafter, an integrated packaging bag containing a plurality of medical drug solution bags 30 may be referred to as an integrated package.
JP 2006-21833 A

  However, if the corrugated cardboard box in which the accumulated package is stored in this manner falls during handling or the like, each medical liquid bag 30 is stored vertically in the corrugated cardboard box. The stress due to is concentrated on the short side of each of the substantially rectangular medical drug solution bags 30 to be landed, that is, on the bottom 33, and there is a problem that each medical drug solution bag 30 is easily broken.

  In order to solve such a problem, as shown in FIG. 8, a method in which the medical drug solution bag 30 is stored in a horizontally long shape in the integrated packaging bag 40 in advance can be considered. If each medical liquid bag 30 is stored in a horizontally long state in advance, when the integrated packaging bag 40 is placed in a cardboard box with the gripping portion 42 facing upward, each medical liquid bag 30 is also horizontally long in the cardboard box. Become. Therefore, the stress when the cardboard box falls together with the box is applied to the side portion 34 instead of the bottom portion 33 of each medical drug solution bag 30. Since the side part 34 corresponding to the long side of the medical drug solution bag 30 is longer than the bottom part 33 corresponding to the short side, the stress applied at the time of dropping is dispersed and relaxed. Therefore, it is considered that the problem of broken bags as described above can be avoided by storing the medical solution bag 30 in a horizontally long manner as described above.

  However, in the method of storing the medical drug solution bag 30 horizontally in the integrated packaging bag 40 as shown in FIG. 8, compared to the method of storing the medical drug solution bag 30 in the vertical direction as shown in FIG. In addition, it is difficult to tightly accommodate the medical drug solution bag 30 with a good fit, so that the medical drug solution bag 30 can easily fall over or move within the integrated packaging bag 40 when the integrated package is transported. There was a problem.

In other words, in the case of FIG. 7, the total circumferential length L ′ of the integrated packaging bag 40 is the length L of the circumferential circumference of the stacked medical drug solution bags 30 (hereinafter referred to as stacking). It is set in advance so that it is about the same length as that of the waistline. Therefore, even if the medical solution bag 30 is stored vertically and then the bottom 41, which is the opening, is heat-sealed with a certain margin, the length L may become longer when the integrated package is used due to gravity applied to the solution. In combination, there is no margin around the body of the medical drug solution bag 30 and a tight state is obtained. Therefore, the medical drug solution bag 30 does not fall down or move in the integrated packaging bag 40 during transportation of the integrated package.
However, when the medical liquid bag 30 is stored horizontally as shown in FIG. 8, the total circumferential length of the integrated packaging bag 40 is the length around the trunk when the plurality of medical liquid bags 30 are stacked. Instead, it corresponds to the circumferential length M in the vertical direction. Therefore, when the bottom 41 is heat-sealed with a certain margin after storage, the circulation length M is hardly increased even when the integrated package is used. As a result, play is generated around the body of the 30 and it is easy for the medical drug solution bags 30 to fall down or move sideways in the integrated packaging bag 40 during transportation. When each medical drug solution bag 30 falls or moves in the integrated packaging bag 40 during transportation, it is not only difficult to transport but also looks bad and the commercial value is lowered. In order to prevent the medical drug solution bag 30 from falling or moving in this way when it is stored in landscape orientation, the bottom 41 of the integrated packaging bag 40 is provided so that play does not occur around the trunk of the medical drug solution bag 30. It is considered that it is sufficient to heat seal tightly without providing a margin. However, in that case, the side portion 34 of the medical drug solution bag 30 together with the bottom portion 41 of the integrated packaging bag 40 may be accidentally sandwiched and heat-sealed, resulting in a problem in heat-sealing workability.

Further, the method for horizontally storing the medical drug solution bag 30 in the integrated packaging bag 40 as shown in FIG. 8 uses a packaging system as compared with the method for storing the medical drug solution bag 30 in the vertical direction as shown in FIG. There was also a problem that workability when the medical drug solution bag 30 was accommodated in the integrated packaging bag 40 was poor.
For example, when a packaging system having a pusher for pushing the medical drug solution bag 30 into the integrated packaging bag 40 is adopted, the medical drug solution bag 30 is pushed into the integrated packaging bag 40 and stored. When the bag 30 is accommodated vertically as shown in FIG. 7, the pusher moves the bottom portion 33 by pushing the bottom portion 33 in the direction of the arrow. When the bottom 33 is pushed in this way, the medical liquid bag 30 has a symmetrical shape with respect to the center line of the medical liquid bag 30 drawn along the pressing direction, and the center of gravity of the medical liquid bag 30 is It will be located on this center line. When the center of gravity is located on the center line along the pressing direction in this way, when the medical liquid bag 30 is pushed and moved by the pusher, the medical liquid bag 30 is stabilized, and this is moved smoothly to be placed in the integrated packaging bag 40. Can be accommodated. However, when accommodated horizontally as shown in FIG. 8, the pusher pushes the side portion 34 in the direction of the arrow, and in this case, the center line of the medical liquid bag 30 pulled along the pushing direction. On the other hand, the medical liquid bag 30 has an asymmetric shape. Therefore, the center of gravity is not located on the center line, and it is difficult to move the medical drug solution bag 30 stably and smoothly, and the accommodation workability is lowered.

  The present invention has been made in view of the above circumstances, and even when medical liquid bags are stored horizontally, these medical liquid bags can be tightly stored so that they do not fall down or move during transportation, and An object of the present invention is to provide an integrated packaging bag having good workability and heat sealing workability of the opening after housing, and an integrated package using the same.

As a result of intensive studies, the inventor formed an opening for inserting a medical solution bag in the side portion of the integrated packaging bag, and when the substantially rectangular medical solution bag was placed horizontally from the opening, the opening In order to complete the present invention, it is possible to tightly accommodate the medical solution bag even when heat-sealing with sufficient margin, and also to improve the accommodation workability and the heat-sealing workability of the opening after the accommodation. It came.
An integrated packaging bag of the present invention is an integrated packaging bag having an accommodating portion for accommodating a plurality of substantially rectangular medical drug solution bags in a horizontally long shape, and a grip portion formed above the accommodating portion. An opening for inserting the medical solution bag is formed in the side portion.
The opening may be temporarily fixed or sealed.
The integrated packaging bag of the present invention is preferably formed from a tubular film, and one end of the tubular film is the opening and the other end is closed.
It is preferable that an opening for taking out the stored medical drug solution bag is formed on the top surface of the storage.

Hereinafter, the present invention will be described in detail.
FIG. 1 is an embodiment of an integrated packaging bag 10 of the present invention. This integrated packaging bag 10 is formed of a resin film, and has a storage portion 11 for storing a plurality of vertically long, substantially rectangular medical drug solution bags 30 as shown in FIG. The side part 12 of the storage part 11 is formed with an opening for inserting the medical liquid bag 30 therein, and the top surface 13 of the storage part 11 is for taking out the stored medical liquid bag 30. An unsealing part 14 formed of a linear perforation (intermittent cut) is formed. Further, in the integrated packaging bag 10, a grip portion 15 is formed above the housing portion 11 in which a pair of belt-shaped resin tapes are heat-sealed in a loop shape, and the medical drug solution bag 30 is accommodated in the integrated packaging bag 10. It is possible to carry the collected package.

As a kind of resin which comprises such an accumulation packaging bag 10, polyolefin, such as polyethylene and polypropylene, is suitable. Polyethylene is particularly preferable, and among them, low-density polyethylene and high-strength linear low-density polyethylene are preferable when the total mass of a plurality of medical drug bags 30 to be accommodated is large.
As for the thickness of the resin film which comprises the accommodating part 11, 40-200 micrometers is preferable, More preferably, it is 50-160 micrometers. In addition, the thickness of the resin tape constituting the grip portion 15 is preferably 70 to 200 μm, more preferably 90 to 180 μm. The width of the resin tape is preferably 1.5 to 3.0 cm. In addition, the structure of the resin film and the resin tape may be a single layer or multiple layers.

Such an integrated packaging bag 10 can be manufactured by the following method, for example.
First, as shown in FIG. 2A, a cylindrical film manufactured by an inflation method or the like is prepared as a resin film, and a linear perforation is provided along the longitudinal direction of the cylindrical film to open the opening portion 14. Form. Next, the opening portion 14 is folded inside the cylindrical film to form the top surface 13 of the housing portion. Next, a portion facing the part folded inward is similarly folded inward along the longitudinal direction to form the bottom surface 16 of the accommodating portion. By such a process, the bottom surface 16 and the top surface 13 are formed at opposing positions, and a pair of front portions 17 a and 17 b are formed between the bottom surface 16 and the top surface 13. At this time, folding length L ₁ of the top surface 13, to form a gripping portion forming region described below, keep longer than folding length L ₂ of the bottom surface 16.
Thereafter, as shown in FIG. 2 (B), the top surface 13 and the pair of front portions 17a and 17b continuous to the top surface 13 are heated linearly along the longitudinal direction of the tubular film in the vicinity of the boundary. Seal. The portions above the linearly sealed portions (indicated by hatching in FIG. 2B) 18a and 18b thus heat-sealed are gripping portion forming regions 19a and 19b, and a strip-shaped resin tape is looped here. By carrying out heat sealing in a shape, the grip portion 15 composed of a pair of handles can be formed. Each of the gripping portion forming regions 19a and 19b formed here is preferable for forming the gripping portion 15 by heat-sealing a strip-shaped resin tape in this way because the film is doubled and has high strength. .
After forming the gripping part 15, one end (not shown in FIG. 2B) of the tubular film is left as it is to be used as an opening, while the other end 20 is heat-sealed and closed. The integrated packaging bag 10 of FIG. 1 can be manufactured.
A plurality of integrated packaging bags 10 can be continuously manufactured by continuously supplying a long cylindrical film having a scroll shape or the like.

In the integrated packaging bag 10 of FIG. 1 manufactured in this way, a plurality of substantially rectangular medical drug solution bags 30 are stored horizontally as shown in FIG. 3, for example, so that a plurality of medical drug solution bags 30 are stored horizontally. 4 can be produced.
That is, a plurality of medical drug solution bags 30 are stacked in a substantially horizontal direction (flat stacking), and then the bottom 33 of these medical drug solution bags 30 is attached to the substantially rectangular medical drug solution bag 30 by a pusher P included in the packaging system. The medical drug solution bag 30 is moved by being pushed in the pressing direction along the longitudinal direction, and is pushed into the integrated packaging bag 10 to be stored horizontally. After accommodation, the opening in the side portion 12 of the integrated packaging bag 10 is heat-sealed and sealed, and then the remaining tubular film is cut off as necessary.

As described above, the integrated packaging bag 10 as shown in FIG. 1 has a form in which an opening is formed in the side portion 12 of the accommodating portion 11. The medical solution bag 30 can be tightly accommodated so that it does not fall or move within the integrated packaging bag 10, and the accommodation workability and the heat sealing workability of the opening after the accommodation are also good. .
That is, in such an integrated packaging bag 10, since the opening is formed in the side portion 12 of the accommodating portion 11, the entire circumferential length of the accommodating portion 11 of the integrated packaging bag 10 (A in FIG. 3). ') Can be fixed to a predetermined length in advance. Therefore, the total length A ′ in the vertical direction is approximately the same as the length around the trunk (A in FIG. 3) when the medical drug solution bags 30 accommodated in the integrated packaging bag 10 are stacked. Even if the side opening is heat-sealed with some margin after the medical liquid bag 30 is stored horizontally from the opening, the margin around the trunk of the medical liquid bag 30 is sufficient. Can be prevented from occurring. Therefore, the opening part of the integrated packaging bag 30 can be sealed without accidentally pinching the medical drug solution bag 30, and the heat seal workability is excellent, and the medical drug solution bag 30 is tightly accommodated, and each medical drug solution bag is provided. 30 can be prevented from falling over or moving.

  When the medical solution bag 30 is accommodated horizontally from the opening formed in the side part 12 of the accommodating part 11 using the packaging system provided with the pusher P, as shown in FIG. Since the bottom 33 of the medical liquid bag 30 is pushed and moved in the direction of the arrow, the center of gravity of the medical liquid bag 30 is located on the center line of the medical liquid bag 30 drawn along the pressing direction. Therefore, the medical drug solution bag 30 can be stably and smoothly moved and stored in the integrated packaging bag 40, and the storage workability is excellent.

  Moreover, since the integrated packaging bag 10 of this example is provided with the handle-like thing which heat-sealed the resin tape in the loop shape as the holding | grip part 15, it is also possible to carry on a shoulder and carry heavy goods. Suitable for transportation. The shape of the gripping portion is not particularly limited, and the gripping portion forming regions 19a and 19b may be punched to form a gripping hole so that the gripping portion can be gripped through the hand. Such a gripping part is preferable in that it is not necessary to separately prepare a belt-shaped resin tape, and an integrated packaging bag can be manufactured only from a tubular film. However, if such a gripping portion is formed on an integrated packaging bag having a large number of medical drug solution bags 30 and a large thickness when the integrated packaging is formed, the gripping portion forming regions 19a, 19b If the gripping holes are not formed after the length in the vertical direction is increased, the pair of gripping holes cannot be gripped together. In that case, the amount of film used increases, leading to an increase in cost, so the gripping portion 15 as shown in FIG. 1 is preferable.

Moreover, the opening part 14 of the integrated packaging bag 10 of this example has a perforation formed in the top surface 13 in a straight line, but the perforation may be a rectangular shape instead of a straight line. Instead of this, it may be an unsealed portion that tears the film using a lead tape or the like. In the form using lead tape, the hermeticity in the integrated package is maintained, and therefore, by using a gas barrier resin as a constituent material of the integrated packaging bag, vacuum packaging and inert gas sealed packaging become possible. preferable.
Although the surface on which the opening part 14 is formed is not particularly limited, when the opening part 14 is formed on the top surface 13 as in the example of FIG. 1, a part of the medical liquid bag 30 is taken out from the integrated package. After that, the integrated packaging bag 10 is not easily torn or torn, and the remaining medical drug solution bag 30 can be carried while being stably stored.

  It should be noted that the opening of the integrated packaging bag 10 may be temporarily fixed so as to be openable or sealed from the standpoint of handling before the medical solution bag 30 is accommodated therein. May be. Since such an opening is closed before the medical drug solution bag 30 is accommodated, dust or the like does not enter the accommodation part, which is preferable in terms of hygiene. The medical liquid bag 30 can be accommodated after the temporary fixing is opened or the vicinity of the opening is cut and opened.

In the manufacturing method of the integrated packaging bag 10 described with reference to FIG. 2, the top surface 13 and the bottom surface 16 of the housing portion 11 are formed after the opening portion 14 is formed. After the top surface 13 is formed, the opening 16 may be formed on the top surface 13 and then the bottom surface 16 may be formed. Further, in the above description, after the gripping portion 15 is formed, the other end 20 of the tubular film is heat sealed and closed, but this order may be reversed. Further, when continuously manufacturing a plurality of integrated packaging bags 10 by continuously supplying a long cylindrical film having a scroll shape or the like, in the longitudinal direction (flow direction) of the supplied cylindrical film On the other hand, the cylindrical film is heat-sealed vertically with a predetermined width, and the heat-sealed other end 20 of one integrated packaging bag 10 and another integrated packaging are cut by cutting the substantially central portion of the heat-sealed portion. It is also possible to form the sealed opening of the bag 10 at the same time.
Furthermore, as the cylindrical film of material, it is preferable to use a cylindrical film formed by an inflation method or the like, but one flat film is folded in two or two flat films are overlapped. After that, a tube formed by fusing the side ends may be used. In addition, a cylindrical film is not necessarily used as a material, and a plurality of planar films may be used to form an integrated packaging bag. According to the method of using a plurality of planar films, a functional film can be used for any of these films. That is, for example, a light-shielding film is used for the front portion and the top surface to maintain the quality of the chemical solution in the medical solution bag 30, and an inexpensive general film is used for the bottom surface. A film having a different function for each part can also be used.

  Further, in the method for manufacturing an integrated package described with reference to FIG. 3, the medical solution bags 30 are stacked in a substantially horizontal direction and pushed and moved by the pusher P included in the packaging system. There is no particular limitation, and the bag 30 may be vertically aligned so that the side portion 34 thereof is up and down, and the bottom portion 33 is pushed by the pusher P, and there is no particular limitation. However, when the thickness of each medical drug solution bag 30 is thin, the stability when the side portions 34 are arranged in the vertical direction so as to be vertically arranged in this way is poor, and therefore it is preferable to store them by the method of FIG. .
