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. 10 and 11, the stopper 112 (port portion) of the infusion container 110 with the hook portion 113 of the infusion container 110 (infusion container) exposed at the top 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. 11). Then, the drip container 110 is hung on a hook while being covered with the packaging bag 101.
After the steps (1) to (3), an injection needle is inserted into the plug 112 of the infusion container 110 to perform infusion.
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 to suspend the drip container 110 by exposing the stopper 112, and the work is complicated. 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. In addition, the package 101 is suitable for an infusion container 110 having a hook 113 that is narrower than the main body 111, as shown in FIG. 10, 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, a packaging bag that can be used as a light-shielding cover as it is during drip is used as a packaging bag that can be used as a light-shielding cover as it is during storage. ing.

[Barrier packaging bag]
Hereinafter, an example of the embodiment of the barrier packaging bag of the present invention will be 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. It is a packaging bag to be stored, and the notch 2 and the weakened portion 3 are formed by opening the port portion 22 side of the stored infusion container 20 and exposing the port portion 22 while storing the main body portion 21.
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 3 and exposes the port part 22 of the accommodated infusion container 20 will become easy.
Moreover, the gas barrier layer mentioned later may serve as the outer layer.

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 3 to excise the lower portion 5 of the packaging bag 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 μm or less, the packaging bag 1 is cut along the weakened portion 3 so that the lower portion 5 of the packaging bag is cut and the port portion 22 of the stored infusion container 20 is exposed. .

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. From the viewpoint of easily tearing the packaging bag 1 along the weakened portion 3, 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.
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 3 and excises the packaging bag lower part 5 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 notch 2 and the weakened portion 3 formed in the packaging bag 1 excise the lower portion 5 of the packaging bag in order to expose the port portion 22 of the infusion container 20 accommodated inside the packaging bag 1 to the outside of the packaging bag 1. Thus, the packaging bag 1 is opened.
As shown in FIG. 2, the position of the weakened portion 3 in the length direction of the packaging bag 1 is the side where 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. It is preferable that the position is close to the end portion 1a and the port portion 22 and the weakened portion 3 can be separated as much as possible. The weakened portion 3 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 3 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 3 due to vibration or the like, and may be exposed from the inside of the packaging bag 1 before use.

  In addition, the packaging bag 1 has two inner surfaces (inner layers 14) of the packaging bag 1 on the side of the port portion 22 with respect to the body portion 21 of the infusion container 20 accommodated therein at two locations on both sides of the port portion 22 in the width direction. The fused parts 4 (two in the present embodiment) are formed. These two fused parts 4 are formed such that the distance a is shorter than the width b of the infusion container 20. Since the distance a between the fusion parts 4 is shorter than the distance b of the infusion container 20, the main body part 21 of the infusion container 20 is bonded to the fusion part 4 even when the packaging bag lower part 5 is cut off and the packaging bag 1 is opened. At this point, it is caught and stays inside the packaging bag 1 (FIG. 3).

Further, the position of the packaging bag 1 in the longitudinal direction at the fusion part 4 is such that the main body part 21 of the infusion container 20 is hooked and stored in the packaging bag 1 while the lower part 5 of the packaging bag is placed. The port portion 22 of the infusion container 20 is exposed to the outside of the packaging bag 1 through the opening 7 formed by cutting. The distance between the fusion part 4 and the opening 7 (weakening part 3) formed by cutting the packaging bag lower part 5 is from the contact part with the fusion part 4 of the body part 21 of the infusion container 20 to the port part 22. It is preferable that it is equal to or shorter than the distance to the base portion.
Although the fused part 4 of the packaging bag 1 is formed in a dot shape, the shape of the fused part 4 is not particularly limited. Moreover, if the main-body part 21 of the infusion container 20 is fastened inside the packaging bag 1, the number will not be restrict | limited, One may be sufficient and three or more may be sufficient.

  The packaging bag 1 is preferably formed with a hook hole 6 for suspending the packaging bag 1. By hooking the hook hole 6 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 3 from the notch 2 to cut out the packaging bag lower portion 5 to form the opening 7. The port portion 22 of the infusion container 20 is exposed (FIG. 3). Thereafter, the infusion can be performed while the infusion container 20 is suspended by hooking the hook into the hook hole 6 and inserting the injection needle into the port portion 22. Thus, in the case of drip in the packaging bag 1, the process until suspension is very simple.

  In addition, the packaging bag of this invention is not limited to the packaging bag 1 illustrated in FIG. For example, the packaging bag of the present invention is preferably provided with both the notch 2 and the weakened portion 3 as in the packaging bag 1 because it is easy to open, but it is a packaging bag in which only the notch 2 is formed. It may be, and the packaging bag in which only the weakening part 3 is formed may be sufficient.

  Further, as shown in FIG. 4, instead of forming the two fused portions 4, the lower part of the packaging bag is heat-sealed with a concave heat sealer so that the width of the concave portion is a, and the notch 2 Even if the packaging bag is torn and the lower portion 5 of the packaging bag is cut off, the packaging bag 1 ′ in which the main body portion 21 of the infusion container 20 is caught by the recess may be used.

  Further, as shown in FIG. 5, in the case of an infusion container 30 having a body portion 31 for storing an infusion solution, a port portion 32 for taking out the infusion solution, and a hook portion 33 for suspending the body portion 31, Furthermore, the packaging bag 8 which formed the melt | fusion part 8a which fuse | melted the inner surface (inner layer) of the packaging bag in the part of the hook part 33 may be sufficient. In the packaging bag 8, since the stored infusion container 30 is more firmly fixed, the work of cutting off the packaging bag lower part 5 is easy. Further, when the infusion container 30 is a polyethylene container, if the inner layer 14 of the packaging bag 8 is a sealant film made of polypropylene, a hook-shaped portion 33 is formed in the width direction of the packaging bag 8 with a stick-shaped heat sealer. By heat-sealing, the fused portion 8a can be formed without fusing the packaging bag 8 and the infusion container 30 (the fused portion 8b is also formed depending on the length of the heat sealer). By not fusing and fixing the packaging bag 8 and the infusion container 30 more than necessary, it becomes easy to separate and discard them after infusion.

  Further, as shown in FIG. 6, it has a main body portion 41 for storing an infusion solution, a port portion 42 for taking out the infusion solution, and a hook portion 43 for suspending the main body portion 41, and a seal portion 41 a (no infusion solution is stored in the main body portion 41. When the infusion container 40 and the inner layer of the packaging bag are made of the same material (for example, polyethylene), in addition to the formation of the fused portion 4, It may be the packaging bag 9 in which the periphery of the hook portion 43 and the thief portion 41a and the packaging bag are fusion-fixed by the fusion-fixing portion 9a. Also in this case, it is preferable not to fuse and fix the packaging bag 9 and the infusion container 40 more than necessary in consideration of separation and disposal.

  In addition to the fusion part 4, a fusion part of a hook part such as the packaging bag 8 illustrated in FIG. 5 and a fusion fixing part such as the packaging bag 9 illustrated in FIG. 6 are formed. It may be a packaging bag.

[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 on the inside of the gas barrier layer 12, the belt-like laminate 10 including the outer layer 11, the gas barrier layer 12, the light shielding layer 13, and the inner layer 14 is manufactured by the various laminating methods described above.

  Next, the weakened part forming machine 50 (the roll 51 and the weakened part forming machine 52 (which is arranged so that the rolls 51 and the roll surfaces are in contact with each other) and the sandpaper 53 having a specific particle size is wound around the roll 51 ( 7), the weakened portion 3a is continuously formed in the outer layer 11 of the strip-shaped laminate 10 along the longitudinal direction of the laminate 10 (FIG. 8). That is, the laminated body 10 is passed between the roll 51 of the weakened part forming machine 50 and the weakened part forming roll 52, and the sandpaper 53 is pressed against the outer layer 11 of the laminated body 10, whereby the weakened part 3a is continuously connected to the outer layer 11. Will form.

  After the weakened portion 3a is formed, the belt-like laminate 10 is folded in half in the short direction with the inner layer 14 inside. Then, three-way heat sealing is performed so that a storage portion for storing the infusion container 20 is formed with the weakened portion 3a side open, and the laminate 10 is cut along the heat sealing portion formed along the short direction. The packaging bag precursor 1A which becomes each packaging bag 1 is obtained (FIG. 9). A hook hole 6 is formed in the heat seal portion at the end in the length direction of the packaging bag precursor 1A. Further, a notch is formed at the end of the packaging bag precursor 1A in the width direction so as to correspond to the weakened portion 3a.

  Thereafter, the infusion container 20 is stored inside the packaging bag precursor 1A so that the port portion 22 is on the open end side (weakening portion 3a side) (FIG. 9), and the end of the packaging bag precursor 1A on the weakening portion 3a side Heat seal the part. Next, the inner surface of the packaging bag is fused to the port portion 22 side of the body part 20 of the stored infusion container 20 to form the fused portion 4 to obtain the packaging bag 1. The fused portion 4 can be formed by heat sealing, impulse sealing, ultrasonic sealing, laser welding, or the like.

In addition, the manufacturing method of the packaging bag of this invention is not limited to the said method. For example, the fusion part 4 may be formed before the packaging bag 1 is sealed. The formation of the weakened portion 3 is not limited to the method using the weakened portion forming machine 50, 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.
In addition, the weakened portion 3a is formed on the laminated body 10 at the center in the short direction, the laminated body 10 is folded in two in the short direction, and the side on which the hook portion 6 is formed is opened and the three-way heat seal is performed. A method may be used in which the infusion container 20 is housed and sealed after the operation.

In addition, the packaging bag 1 ′ illustrated in FIG. 4 stores the infusion container 20 in the packaging bag precursor 1A so that the port portion 22 is on the open end side, and then the open end side of the packaging bag precursor 1A. Can be obtained by heat sealing with a concave heat sealer.
Further, the packaging bag 8 illustrated in FIG. 5 forms the fused portion 4 in the same manner as the packaging bag 1, and further heat seals the portion of the hook portion 33 with a rod-shaped heat sealer or the like to fuse the fused portion 8a and the fused bag. It can be obtained by forming the landing portion 8b. The fused portion 8a and the fused portion 8b may be formed by impulse sealing, ultrasonic sealing, laser welding, or the like.
In addition, the packaging bag 9 illustrated in FIG. 6 forms the fusion part 4 in the same manner as the packaging bag 1, and further forms the fusion fixing part 9a by heat sealing, impulse sealing, ultrasonic sealing, laser welding, or the like. Can be obtained.

  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. In addition, the barrier packaging bag of the present invention is easy to operate because the port portion can be exposed from the formed opening only by opening the lower portion of the packaging bag along the weakened portion.

  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 drip with a simple operation. Therefore, it is possible to prevent the infusion from being deteriorated both during storage and at the time of infusion, and it is very useful as a packaging bag for storing the infusion container.
