Description

  The present invention relates to a barrier packaging bag for storing an infusion container.

  For the infusion of infusion, an infusion container having a main body portion that contains the infusion solution, a port portion that takes out the infusion solution from the main body portion, and a hook portion that suspends the main body portion is widely used. In the case of infusion, the infusion solution containing amino acids and vitamins is particularly susceptible to ultraviolet rays, so that the infusion solution may be altered during the infusion. Further, while the infusion container containing the infusion solution is stored, the infusion solution may be deteriorated by ultraviolet rays or water vapor.

  Therefore, conventionally, an infusion container is stored in a packaging bag having a light-shielding property and a gas barrier property, and the infusion container is removed from the packaging bag when instilled, and a new light-shielding cover having a light-shielding property is used. Used to cover. However, this method has a problem that the operation during the infusion is complicated and the amount of waste increases. Therefore, a packaging bag for an infusion container that can also be used as a light-shielding cover at the time of infusion has been desired.

  Patent Document 1 discloses a packaging bag that prevents deterioration of the quality of an infusion solution during storage of the infusion container and can be used as it is as a light-shielding cover during infusion. Specifically, as shown in FIGS. 9 and 10, the plug 112 (port portion) of the infusion container 110 with the hook portion 113 of the infusion container 110 (infusion container) exposed at the upper part of the packaging bag 101. A packaging bag 101 is shown in which the lower portion 105 of the packaging bag 101 located in the vicinity is cut out to expose the plug 112.

When this packaging bag 101 is used for infusion, the following steps are performed.
Step (1): The lower portion 105 of the packaging bag 101 is opened along the lower tear guide line 102 from the notch 104a formed in the packaging bag 101.
Step (2): Similarly to step (1), the lower portion 105 of the packaging bag 101 is cut along the upper tear guide line 103 from the notch 104b formed in the packaging bag 101.
Step (3): The upper center portion 106 of the packaging bag 101 is cut along the upper tear guide line 104c, and the hook portion 113 of the drip container 110 is exposed from the opening 107 formed in the packaging bag 101 (FIG. 10). .
After the steps (1) to (3), the drip container 110 is hung on the hook while being covered with the packaging bag 101, and the drip is carried out by inserting a syringe needle into the plug 112 of the infusion container 110.
JP 2006-167050 A

The packaging bag 101 of patent document 1 can use the packaging bag 101 which has light-shielding property as it is as a light-shielding cover in the case of drip by performing an operation | work like process (1)-(3). However, in this packaging bag 101, the above three steps must be performed before the stopper 112 is exposed and the drip container 110 is suspended, and the work is complicated. ) Also occurred, and handling was inconvenient. Further, in the above-described process, the plug body 112 portion of the infusion container 110 may be in the way and the lower portion 105 of the packaging bag 101 may be difficult to remove. Furthermore, when the lower side of the packaging bag 101 is opened in the steps (1) and (2), the infusion container 110 may jump out from the inside of the packaging bag 101 and fall, so that the operation has to be performed carefully. Further, as shown in FIG. 9, the package 101 is suitable for an infusion container 110 having a hook portion 113 having a narrower width than the main body 111, but a hook hole is formed at the end of the main body 111. In the case of an infusion container having such a shape (the width of the hook portion 113 is equal to the width of the main body portion 111), it is difficult to sufficiently expose the hook portion to the outside of the packaging bag 101.
For the reasons described above, the quality of the infusion solution during storage of the infusion container is suppressed, and as a packaging bag that can be used as it is as a light-shielding cover during infusion, the operation when used for infusion is simple and becomes fine garbage. A packaging bag that does not produce an open piece is desired.

  Therefore, the present invention suppresses infusion quality deterioration during storage of the infusion container, can be used as it is as a light-shielding cover during infusion, and the work for use in infusion is simple and does not produce an open piece that becomes fine garbage. Intended for barrier packaging bags.

The barrier packaging bag of the present invention is a packaging bag for storing an infusion container having a main body portion for storing an infusion solution and a port portion for taking out the infusion solution, and the packaging bag is made of a laminate having a gas barrier layer and a light shielding layer. The weakening part which forms the opening which exposes the said port part to the exterior of this packaging bag is accommodated in the said packaging bag, storing the said main-body part of the said infusion container.
In the barrier packaging bag of the present invention, it is preferable that a hook hole for suspending the packaging bag is formed in the packaging bag.

  The barrier packaging bag of the present invention can suppress deterioration of the quality of the infusion solution during storage of the infusion container, and can be used as it is as a light-shielding cover during infusion. Moreover, the operation | work at the time of using for an infusion is simple and does not produce the opening piece which becomes fine garbage.

[Barrier packaging bag]
The barrier packaging bag of the present invention is a packaging bag for storing an infusion container having a main body portion for storing an infusion solution and a port portion for taking out the infusion solution, and the packaging bag is made of a laminate having a gas barrier layer and a light shielding layer. . Moreover, the weakening part which forms the opening which exposes the said port part to the exterior of this packaging bag is formed in the packaging bag of this invention, storing the said main-body part of the said infusion container.
Hereinafter, an example of an embodiment of the barrier packaging bag of the present invention will be shown and described in detail.

As shown in FIG. 2, the barrier packaging bag 1 (hereinafter referred to as “packaging bag 1”) of the present embodiment includes an infusion container 20 having a main body portion 21 that contains an infusion solution and a port portion 22 that takes out the infusion solution. A weakening portion 2 is formed which is a packaging bag to be stored and forms an opening that exposes the port portion 22 to the outside of the packaging bag 1 while the main body portion 21 is stored.
As shown in FIG. 1, the packaging bag 1 includes a laminate 10 in which an outer layer 11, a gas barrier layer 12, a light shielding layer 13, and an inner layer 14 are laminated in order from the outermost layer.

The outer layer 11 is a layer in contact with the outside air in the laminated body 10 forming the packaging bag 1 and plays a role of preventing the inner gas barrier layer 12 from being damaged and maintaining the gas barrier property.
The outer layer 11 is preferably a polyethylene terephthalate (PET) film from the viewpoint of rigidity, transparency, and pinhole resistance due to bending and wear. In addition to the PET film, a film of polyethylene, polypropylene, polyamide, ethylene / vinyl alcohol copolymer, or the like may be used. As these films, for example, a biaxially stretched film or a monolayer of a uniaxially stretched film, or a laminated film can be used.

The thickness of the outer layer 11 is preferably 12 to 25 μm, and particularly preferably 12 to 20 μm. If the thickness of the outer layer 11 is 12 μm or more, the effect of protecting the gas barrier layer 12 on the inner side can be easily obtained. Moreover, if the thickness of the outer layer 11 is 25 micrometers or less, the operation | work which tears the packaging bag 1 along the weakening part 2 and exposes the port part 22 of the accommodated infusion container 20 will become easy.
The outer layer 11 may also serve as a gas barrier layer 12 described later.

The gas barrier layer 12 is a layer that imparts gas barrier properties such as oxygen barrier properties and water vapor barrier properties to the packaging bag 1.
The gas barrier layer 12 is, for example, a metal foil film made of a metal such as copper, aluminum, or magnesium; a deposited film obtained by depositing silica, aluminum, alumina, or the like on a film made of a polyester-based resin, a polyamide-based resin, or the like; 5-100 μm Metal foil laminated film obtained by sandwiching a metal foil having a thickness between PET resin and polypropylene resin; K-coated film obtained by coating polyvinylidene chloride (PVDC) on a film such as PET or cellophane; Organic system having barrier properties and / or Examples thereof include a coated barrier film in which an inorganic barrier material is coated on a film made of polyester or polyamide. The above-described vapor deposition layer and barrier coat layer are preferably provided so as to be inside the gas barrier layer 12. In the case of the gas barrier layer 12 having such a form, the gas barrier layer 12 can also serve as an outer layer.
In addition, films using polyvinyl alcohol resin (PVA), ethylene / vinyl alcohol copolymer (EVOH), PVDC, and metaxylylenediamine polyamide resin (MXD) as film raw materials, and films using these raw materials A laminated film obtained by laminating the above-described other gas barrier film by a dry laminating method or the like, and a coextruded barrier film obtained by laminating these raw materials and a polyolefin resin or the like by coextrusion can also be used.

The oxygen transmission rate as the oxygen barrier property of the index of the gas barrier layer 12 ^is preferably 0~50ml / m 2 / 24hrs / MPa , and more preferably 0~20ml / m 2 / 24hrs / MPa . If the oxygen transmission rate of the gas barrier layer 12 is equal to or less than ^{50ml / m 2 / 24hrs / MPa} , the effect of preventing the deterioration of the infusion when that store infusion container 20 becomes higher.
Further, the water vapor permeation amount of the water vapor barrier property of the index of the gas barrier layer 12 is preferably 0~30g ^/ m 2 ^/ 24hrs, more preferably 0~10g ^/ m 2 ^/ 24hrs. If the water vapor permeation amount of the barrier layer 12 is equal to or less than 30g ^/ m 2 / 24hrs, the effect of preventing the deterioration of the infusion when that store infusion container 20 becomes higher.

  The thickness of the gas barrier layer 12 is preferably 7 to 30 μm, and more preferably 7 to 15 μm. If the thickness of the gas barrier layer 12 is 7 μm or more, the packaging bag 1 having excellent gas barrier properties can be easily obtained. Moreover, if the thickness of the gas barrier layer 12 is 30 μm or less, the work of tearing the packaging bag 1 along the weakened portion 2 and exposing the port portion 22 of the infusion container 20 becomes easy.

The light shielding layer 13 is preferably formed by printing inside the gas barrier layer 12 with a light shielding colored ink as in this example. The light shielding layer 12 may be formed between the gas barrier layer 12 and the outer layer 11 by printing on the outside of the gas barrier layer 12. Further, printing may be performed on the inner side of the outer layer 11, and a light shielding layer may be provided between the gas barrier layer 12 and the outer layer 11. As the light-shielding colored ink, common inks such as white and yellow used for imparting light-shielding properties to the packaging bag can be used.
In addition, a known ultraviolet absorber or the like may be included in the outer layer, and the outer layer may also serve as a light shielding layer.

  When the light-shielding layer 13 is formed by printing with a light-shielding colored ink, the thickness is preferably 2 to 15 μm. If the thickness of the light shielding layer 13 is 2 μm or more, sufficient light shielding properties are easily obtained. Moreover, if the light shielding layer 13 is 15 micrometers or less, the operation | work which tears the packaging bag 1 along the weakening part 2 and exposes the port part 22 of the accommodated infusion container 20 will become easy.

The inner layer 14 is preferably a heat-sealable film, and examples thereof include a sealant film made of a polyolefin film such as polyethylene or polypropylene. Among these, high-density polyethylene, medium-density polyethylene, low-density polyethylene, and linear low-density polyethylene are preferable, and a stretched film of low-density polyethylene is particularly preferable because the packaging bag 1 is easy to tear along the weakened portion 2.
Moreover, what extruded these resin on the film which forms the gas barrier layer 12 by extrusion lamination is good also as the inner layer 14. FIG.

  The thickness of the inner layer 14 is preferably 20 to 50 μm, and more preferably 20 to 40 μm. If the thickness of the inner layer 14 is 20 μm or more, it is easy to make a bag by heat sealing. Moreover, if the thickness of the inner layer 14 is 50 micrometers or less, the operation | work which tears the packaging bag 1 along the weakening part 2 and exposes the port part 22 of the infusion container 20 will become easy.

  A known method can be used as a method of manufacturing the laminate 10. For example, the outer layer 11, the gas barrier layer 12 in which the light shielding layer 13 is formed by printing, and the inner layer 14 are bonded together by a dry laminate method or a sand laminate method to form a laminate. Further, the inner layer 14 may be formed by an extrusion laminating method.

The weakening part 2 formed in the packaging bag 1 exposes the port part 22 of the infusion container 20 accommodated in the packaging bag 1 to the outside while the main body part 21 is accommodated in the packaging bag 1. It is for forming the opening to be made.
The weakening part 2 is formed so that the length a becomes shorter than the width b of the infusion container 20. By providing such a weakened portion 2, when the packaging bag 1 is cut along the weakened portion 2 to form the opening 4, the length of the opening 4 (the same as the length a of the weakened portion 2) is the infusion container. Therefore, when the port portion 22 is exposed, the main body portion 21 of the infusion container 20 does not come out of the opening 4 of the packaging bag 1 and remains housed inside (FIG. 3). ).

Further, the weakened portion 2 is formed so as not to impair the gas barrier properties of the gas barrier layer 12. In this example, the weakened portion 2 is formed in the outer layer 11 portion. By forming the weakened part 2 without damaging the gas barrier layer 12, it is possible to prevent the gas barrier property of the packaging bag 1 from being deteriorated in the weakened part 2.
However, in the case where a gas barrier layer is formed by metal vapor deposition, metal foil, PVDC, etc. only on the inside of the base material using PET or the like and laminated with the outer layer 11 and the inner layer 14, the gas barrier property is not impaired. The weakened portion 2 may be formed as far as the base material portion.

The position where the weakened portion 2 is formed corresponds to the position of the port portion 22 of the infusion container 20 to be accommodated in the width direction of the packaging bag 1 and may be a position where the port portion 22 can be exposed from the formed opening 4. That's fine.
As shown in FIG. 2, the position of the weakened portion 2 in the length direction of the packaging bag 1 is the side on which the port portion 22 of the stored infusion container 20 and the port portion 22 in the length direction of the packaging bag 1 are located. A position where the port portion 22 can be exposed from the formed opening 4 between the end portion 1a and the end portion 1a is closer to the end portion 1a and the port portion 22 and the weakened portion 2 can be separated as much as possible. It is preferable that The weakened portion 2 may be provided so as to be close to the port portion 22 of the infusion container 20 accommodated in the packaging bag 1, but if the weakened portion 2 and the port portion 22 are close to each other, strong vibration is applied in transportation or the like. In such a case, the port portion 22 may break through the packaging bag 1 at the weakened portion 2 due to vibration or the like, and may be exposed from the inside of the packaging bag 1 before use.

  In addition, as shown in FIG. 2, the packaging bag 1 is preferably heat-sealed in a region of the weakened portion 2 on both sides in the width direction of the packaging bag 1. As described above, since the whole area of the both ends in the width direction of the packaging bag 1 in the weakened portion 2 is heat-sealed, both end portions of the weakened portion 2 are hardly torn, and the opening 4 to be formed becomes larger than necessary. It is easy to suppress. Further, when the port portion 22 is exposed from the opening 4, it is easy to suppress the opening 4 from being greatly opened due to the force applied to the opening 4 by the main body portion 21. In addition, as shown in FIG. 2, heat sealing of the regions on both sides in the width direction of the packaging bag 1 in the weakened portion 2 and sealing by heat sealing of the end portion on the weakened portion 2 side in the length direction of the packaging bag 1, If it is carried out at once with a concave heat sealer, bag-making work can be performed more easily.

  The packaging bag 1 is preferably formed with a hook hole 3 for suspending the packaging bag 1. By hooking the hook hole 3 on the hook, drip can be performed in a state where the packaging bag 1 and the infusion container 20 accommodated therein are suspended. When the packaging bag does not have a hook hole, for example, a method of suspending the packaging bag with a clip or the like can be used. Thus, the packaging bag of this invention is applicable also to the infusion container which does not have a hook hole.

  When the packaging bag 1 described above is used for infusion, the packaging bag 1 is first torn along the weakened portion 2 to form the opening 4, and the port portion 22 of the infusion container 20 is exposed from the formed opening 4. Thereafter, the infusion can be performed while the infusion container 20 is suspended by hooking the hook into the hook hole 3 and inserting the injection needle into the port portion 22. Thus, in the case of drip in the packaging bag 1, since there are only two steps until suspension, there are few work steps and it is easy. Further, there are no unsealed pieces that become fine dust.

In addition, the packaging bag of this invention is not limited to the aspect illustrated in FIG. For example, as shown in FIG. 4, a weakened portion is formed from the end portion to the end portion in the width direction of the packaging bag, and the middle two places are heat-sealed in the form of dots to form the fusion points 4a and 4a. Accordingly, the packaging bag 4 in which the weakened portion 2 having the length a is formed may be used.
Moreover, as shown in FIG. 5, the weakening part 2 of length a is provided previously, and the packaging bag 5 by which the both ends are not heat-sealed may be sufficient.
However, the packaging bag 1 illustrated in FIG. 2 is preferable because it is easy to manufacture the packaging bag and easily suppresses the opening formed by tearing the weakened portion from becoming larger than necessary.

Moreover, the weakening part formed in the packaging bag of this invention may be formed not only in one side like the packaging bag 1, but in both surfaces, and when forming in both surfaces, the width in those packaging bodies The position in the direction and the length direction are not necessarily the same.
The packaging bag of the present invention may have a notch so that the packaging bag can be completely opened. By providing a notch for completely opening the packaging bag, it becomes easy to take out the infusion container from the packaging bag after the drip and discard them separately. In addition, even when an infusion container containing an infusion that does not require the packaging bag to be used as a light-shielding cover is contained, the infusion container can be easily taken out and instilled.

[Production method]
Hereinafter, as a method for manufacturing the packaging bag of the present invention, a method for continuously manufacturing the packaging bag will be described using the aforementioned packaging bag 1 as an example.
After the light shielding layer 13 is formed by printing the inside of the gas barrier layer 12, the belt-like laminate 10 in which the outer layer 11, the gas barrier layer 12, the light shielding layer 13, and the inner layer 14 are sequentially laminated is manufactured by the various laminating methods described above. To do.

  Next, a weakened part forming machine 30 (a roll 31 and a weakened part forming roll 32 that is disposed so that the rolls 31 and the roll surfaces are in contact with each other, and a sandpaper 33 having a specific particle size is wound on the surface. 6), the weakened portion 2a is continuously formed in the outer layer 11 of the strip-shaped laminate 10 along the longitudinal direction of the laminate 10 (FIG. 7). That is, the laminated body 10 is passed between the roll 31 of the weakened part forming machine 30 and the weakened part forming roll 32, and the sandpaper 33 is pressed against the outer layer 11 of the laminated body 10, whereby the weakened part 2a is continuously connected to the outer layer 11. Will form.

  After the weakened portion 2a is formed, the belt-like laminated body 10 is folded in half in the short direction with the inner layer 14 inside. Then, the three-way heat seal is performed so that the storage portion for storing the infusion container 20 is formed with the weakened portion 2a side open, and the laminate 10 is cut along the heat seal portion formed along the short direction. The packaging bag precursor 1A which becomes each packaging bag 1 is obtained (FIG. 8). A hook hole 3 is formed in the heat seal portion at the end in the length direction of the packaging bag precursor 1A.

  Thereafter, the infusion container 20 is accommodated inside the packaging bag precursor 1A so that the port portion 22 is on the open end side (weakening portion 2a side) (FIG. 8), and the weakening portion 2a in the width direction of the packaging bag precursor 1A. The package having the weakened portion 2 (length a) is sealed by heat-sealing the end of the weakened portion 2a side of the packaging bag precursor 1A with a concave heat sealer so that the length of the package is 1a. Bag 1 is obtained.

In addition, the manufacturing method of the packaging bag 1 is not limited to this. For example, the formation of the weakened portion 2 is not limited to the method using the weakened portion forming machine 30, and may be a method using a laser (CO ₂ laser) or a blade as long as the gas barrier property of the gas barrier layer is not impaired.
Further, the three-way heat seal is performed by setting the position of the weakened portion 2a to the laminated body 10 to the central side in the short direction, folding the laminated body 10 in the short direction, and opening the side on which the hook portion 3 is formed. A method may be used in which the infusion container 20 is housed and sealed after the operation.

  Moreover, after manufacturing the packaging bag precursor 1A like the packaging bag 1, the packaging bag 4 illustrated in FIG. 4 accommodated the infusion container 20 and separated by the length a located in the middle of the weakened portion 2a. It can manufacture by heat-sealing two points and the edge part by the side of the weakening part 2a of 1 A of packaging bag precursors. However, since the packaging bag 4 using such a method may cause the position of the packaging bag precursor 1A to shift or the position of the stored infusion container 20 to shift, it heats in two desired spots. Difficult to seal. On the other hand, the manufacturing method of the packaging bag 1 by the above-mentioned method is more advantageous in that the concave heat sealer can perform sealing while moving the port portion 22 inside the packaging bag precursor 1A so as not to heat seal. Are better.

  Further, in the packaging bag 5 illustrated in FIG. 5, for example, the weakened portion forming roll 32 of the weakened portion forming machine 30 is shaped like a gear so that the sandpaper 33 is intermittently pressed against the laminate 10. Thus, after the weakened portion 2 having the length a is intermittently formed, three-way heat sealing is performed in the same manner as in the case of the packaging bag precursor 1A, the infusion container 20 is accommodated, and the open end portion is heat sealed and sealed. Can be manufactured.

  Since the barrier packaging bag of the present invention described above has light shielding properties and gas barrier properties, it is possible to suppress deterioration of the quality of the infusion solution during storage of the infusion container. In addition, it can be used as a light shielding cover as it is during infusion. Moreover, the barrier packaging bag of the present invention can be used for infusion only by performing two steps of tearing the packaging bag along the weakened portion and exposing the port portion from the opening formed thereby, so that the operation is simple and fine. There is no open piece that becomes garbage.

  Since the gas barrier packaging bag of the present invention can be used not only as a storage bag during storage of an infusion container but also as a light-shielding cover during infusion, it can prevent deterioration of the infusion during both storage and infusion. Therefore, it is very useful as a packaging bag for storing an infusion container.
