Description

  The present invention relates to an exterior bag having an ultraviolet blocking performance for accommodating an infusion solution container, and more specifically, an opening that exposes a hook portion of an infusion container by tearing the upper center of the exterior bag in one direction with a fingertip. The present invention relates to an improved infusion container outer bag so that it can be easily formed and the hook portion of the infusion container can be centered on the center line of the outer bag.

  Conventionally, infusion containers containing infusion solutions for infusions that are easily altered by light such as ultraviolet rays are stored and distributed in exterior bags with light blocking performance, and the exterior bags are discarded when infusions are used (during infusion). Another new protective cover was put on. However, this protective cover also has a problem of high cost because it requires light blocking performance like the exterior bag.

  Under such circumstances, the following exterior bags that can be used as protective covers without discarding have already been proposed.

  One of them is a three-way heat-sealed bag with light-shielding properties.The shape of the upper heat-sealed part is a reverse concave shape that serves as a hook outlet for the drip container. An anti-contamination bag provided with an upper V-notch and a lower V-notch and sterilized by radiation (Patent Document 1). This anti-contamination bag can remove the hook part of the drip container by tearing the reverse concave upper heat seal part from the upper V-notch, and it can be drip into the infusion outlet of the drip container by tearing the lower part of the bag from the lower notch. Therefore, it can also be used as a protective cover during infusion.

  The other is provided with a V-shaped tear guide line for forming an opening that exposes the hook portion of the drip container at the center of the bag, and a tear guide line parallel to the lower end side at the bottom of the bag. Is a drip container packaging bag (Patent Document 2). This drip container packaging bag can also be taken out by cutting the upper part of the bag along the V-shaped tear guide line, and the hook part of the drip container can be taken out, and the lower part of the bag along the tear guide line parallel to the lower end side. When the tube is cut, an infusion tube can be connected to the infusion outlet of the infusion container, so that it can also be used as a protective cover during infusion.

Japanese Patent No. 3240253 JP 2006-167050 A

  However, when the anti-contamination bag of Patent Document 1 forms an opening for taking out the hook portion of the drip container, it tears in one direction from the upper V notch on either side of the left side to the reverse concave portion of the upper heat seal portion, Furthermore, it is necessary to cut in the reverse direction from the upper V notch on the opposite side to the reverse concave part of the upper heat seal part, and the upper heat seal part is opened in one step from the upper V notch on either side in one step. Since the portion cannot be formed, the opening workability is not so good, and there is a problem that it takes time to prepare for the drip.

  Similarly, the drip container packaging bag of Patent Document 2 is also cut at the pointed lower end of the V-shaped tear guide line when it is to be cut in one direction from one end to the other end of the V-shaped tear guide line. Since it is easy to form a tear in a different direction from the tear guide line, if you want to tear along the V-shaped tear guide line, you can cut the V-shaped tear guide line from one end of the V-shaped tear guide line. There was a problem in that the opening workability was not good because it had to be cut in one direction up to the sharply lower end, and in the opposite direction from the other end of the V-shaped tear guide line to the sharpened lower end. .

  In addition, since the bags of Patent Documents 1 and 2 do not have a function of centering the hook portion of the drip container at the center in the width direction of the bag, an opening (outlet) formed by cutting the upper portion of the bag is provided. There was a problem that the position of the hook part of the drip container was shifted and it was difficult to take out the hook part of the drip container from the opening at the top of the bag. Moreover, since the size of the opening formed by cutting the upper portion of the bag is constant, if the size of the drip container or the hook portion to be accommodated changes, the hook from the opening at the upper portion of the bag changes depending on the size. Some parts could not be removed.

The present invention has been made under the above circumstances, and the first problem to be solved is to cut the hook portion of the infusion container (infusion container) by tearing the upper center of the outer bag in one direction with a fingertip in one step. An object of the present invention is to provide an infusion container outer bag in which an opening to be exposed can be formed very easily.
A second problem is to provide an infusion container outer bag that can be easily exposed from the opening of the outer bag by centering the hook part of the infusion container on the center line of the outer bag.
Furthermore, the third problem is to provide an infusion container outer bag that can center the hook part of the infusion container on the center line of the outer bag and can suspend the infusion container without tearing the upper center of the outer bag. is there.
And in preferable embodiment, it enables it to change the magnitude | size of the said opening part of an exterior bag, and also improves the tearability by improving the material film of an exterior bag.

In order to solve the first problem, a first infusion container outer bag according to the present invention is an outer bag having a light blocking performance for accommodating an infusion container, and the upper part of the outer bag has an infusion container. A concave tear guide line that can be torn in one direction is provided for forming an opening that exposes the hook portion.
Here, “a concave shape that can be cut in one direction” means a concave shape that can be cut in one step without interruption from one end of the tear guide line to the other end of the tear guide line. Means a so-called concave shape that can be cut in a one-way, and specifically, a V-shape, a semi-elliptical shape, and a semi-circular shape in which a lower portion is bent into an arc shape as described later. Shape, arc shape, and U-shape with rounded corners at both lower corners.

In the 1st infusion container exterior bag of this invention, it is preferable that the concave shape of a tearing guide line is made into the V shape which made the lower part curved in an arc shape. And it is preferable to provide two or more tear guide lines at intervals in the up-down direction in the upper center of the exterior bag.
Moreover, it is preferable to form an oblique seal part on the both sides of the upper part of the outer bag so that the shoulder parts of the infusion container are abutted and the hook part of the infusion container is centered on the center line of the outer bag.
Furthermore, the outer bag is a laminate film in which a polyolefin inner layer film, a polyamide outer layer film, and a polyester intermediate layer film are laminated and integrated through an adhesive layer, and the outer layer film of the intermediate layer film It is preferable that the bag is made of a laminate film having an ultraviolet absorbing layer on the side surface.

Next, the second infusion container outer bag according to the present invention is an outer bag having a light blocking performance for accommodating the infusion container, and the shoulders of the infusion container are held on both sides of the upper part of the outer bag. In addition, an oblique seal portion for centering the hook hole of the infusion container on the center line of the outer bag is formed in a C shape, and a V-shaped tear guide line is provided in the upper center of the outer bag. Is.
The second infusion container outer bag is also preferably formed with a plurality of V-shaped tearing guide lines at intervals in the vertical direction at the upper center of the outer bag.

  Furthermore, the third infusion container outer bag according to the present invention is an outer bag having ultraviolet blocking performance for accommodating the infusion container, and the shoulders of the infusion container are held on both sides of the upper part of the outer bag. The hook hole of the infusion container is centered on the center line of the outer bag and a diagonal seal is formed in a letter C shape, and the hook opening is placed in the upper center of the outer bag so as to overlap the hook part of the centered infusion container. Or a slit guide line for forming the opening.

The first infusion container outer bag of the present invention is provided with a concave tear guide line capable of tearing in one direction for forming an opening that exposes the hook portion of the infusion container at the upper center of the outer bag. Therefore, the upper center of the outer bag is smoothly and quickly cut in one step without interruption from one end of the tear guide line along the tear guide line to the other end of the tear guide line. And the hook part of an infusion container can be exposed from this opening part. In this way, the infusion container outer bag of the present invention can quickly and reliably expose the hook part of the infusion container and hang it on the collar part of the infusion pole so that the infusion container can be suspended. Can improve the efficiency and reduce the burden on nurses.

  The shape of the tearing guide line is not limited as long as it is a concave shape that can be torn in one direction, and in particular, when the concave shape of the tearing guide line is a V-shape in which the lower part is bent in an arc shape, There is an advantage that it can be cut cleanly and smoothly in one step along the cutting guide line from one end to the other end, for example, in one direction like a semicircular or semi-elliptical cutting guide line Although it can be cut, it does not occur that it tends to be cut in the direction away from the cutting guide line near the other end of the cutting guide line.

  And when a plurality of concave tearing guide lines that can be torn in one direction are provided at intervals in the vertical direction at the upper center of the outer bag, the upper part of the outer bag is selected by selecting the tearing guide line By tearing the center, there is an advantage that a tear opening having an optimum size corresponding to the size of the infusion container can be formed and the hook hole of the infusion container can be reliably exposed.

  In addition, if the shoulders of the infusion container are abutted on both sides of the upper part of the outer bag and the hook part of the infusion container is centered on the center line of the outer bag, a diagonal seal is formed in a C shape. The hook portion of the infusion container centered by the letter-shaped oblique seal portion is exposed without being displaced from side to side from the opening formed by tearing the upper center of the outer bag in one direction along the tear guide line. Therefore, the preparation of the infusion can be efficiently performed by hooking the exposed hook portion of the infusion container on the collar portion of the infusion pole. In the state where the infusion container is suspended, the oblique seal portions formed in a C shape are hooked on both shoulders of the infusion container, so that the outer bag does not fall off until the drip is finished, and the infusion solution is used as a protective cover. The infusion solution inside the container can be protected from light such as ultraviolet rays.

  Further, the outer bag is a laminated film in which a polyolefin-based inner layer film, a polyamide-based outer layer film, and a polyester-based intermediate layer film are laminated and integrated through an adhesive layer, and the outer-layer film of the intermediate-layer film When the bag is made of a laminate film with an ultraviolet absorbing layer on the side surface, the adhesive strength between the intermediate layer film and the inner layer film is improved, and the inner layer film with poor tearability is easily combined with the intermediate layer film. Since it becomes torn, there is an advantage that the tearability along the tear guide line of the outer bag is further improved.

Next, in the second infusion container outer bag of the present invention, both shoulders of the infusion container accommodated therein are stopped by diagonal seal parts formed in a C shape on both sides of the upper part of the outer bag, Since the hook part of the infusion container is centered on the center line of the outer bag, if the upper center of the outer bag is cut along the V-shaped tear guide line, the hook part of the centered infusion container is displaced from side to side. Without being exposed, it will be exposed from the cut opening. Thus, the second infusion container outer bag of the present invention can also hang the infusion container by centering the hook part of the infusion container so that it can be quickly exposed from the opening and hooked on the collar of the drip pole. The infusion bag can be efficiently prepared, and in the state where the infusion container is suspended, the diagonally sealed portions formed in a letter C shape are hooked on both shoulders of the infusion container. The infusion solution inside the infusion container can be protected from light such as ultraviolet rays as a protective cover without dropping until the infusion is finished.
And in this 2nd infusion container exterior bag, what provided the V-shaped tear guide line in the upper part of the exterior bag at intervals up and down selects the tear guide line, By opening the upper center, it is possible to form an opening having an optimum size corresponding to the size of the infusion container.

  In addition, the third infusion container outer bag includes a hook hole of the infusion container, a hook opening provided at the upper center of the outer bag so as to overlap the hook hole, or a tear guide line for forming the opening. Even if the position of the infusion container is displaced, both the shoulder parts of the infusion container are stopped against the diagonal seal part in the shape of a letter C, so that the hook part of the infusion container can be easily centered and the hook opening part of the outer bag or the opening part Can be overlapped with the tearing guide line for forming and hooked on the buttocks of the drip pole in the state of being overlapped, or by opening the hook opening formed by tearing the tearing guide line. The preparation work for the drip can be performed efficiently by hooking it on the collar part of the drip pole so as to overlap the part. Thus, since the thing which formed the opening part for hooks in the 3rd infusion container exterior bag previously does not need to tear the upper center of a bag, workability | operativity improves that much. Then, the outer bag in which the hook opening is hooked on the pole collar and hung can be protected from light such as ultraviolet rays as a protective cover without dropping off until the drip is finished.

Is shown. It is a front view which shows one Embodiment of the 2nd infusion container exterior bag which concerns on this invention. It is a partial front view which shows one Embodiment of the 3rd infusion container exterior bag which concerns on this invention. It is a front view of the infusion container exterior bag of the embodiment at the time of drip.

  FIG. 1 shows an embodiment of a first infusion container outer bag according to the present invention. The infusion container exterior bag A shown in FIG. 1 is formed by heat-sealing the upper edge 1a and the left and right side edges 1b, 1c of the front and rear synthetic resin laminate films 1, From the opening, the infusion container 2 is accommodated in the bag with its infusion outlet 2a facing downward. And the lower end edge 1d of the exterior bag A is heat-sealed after accommodating the infusion container 2, so that the infusion container 2 is shielded from the outside air.

  On both sides of the upper portion of the outer bag A, a pair of left and right diagonal seal portions 3 and 3 for holding the shoulder portions 2b and 2b of the infusion container 2 (both shoulder portions cut obliquely rounded) are provided on the outer bag A. The shoulders 2b and 2b of the infusion container 2 accommodated in the bag are stopped by the above-described oblique seal portions 3 and 3. The hook portion (hook hole) 2c formed at the center of the upper end portion of the infusion container 2 is centered on the center line CL of the outer bag A. The oblique seal portions 3 and 3 of this embodiment are all formed linearly, but may be formed to be slightly convex or concave.

  The inclination angle (inclination angle with respect to the horizontal) of the oblique seal portions 3 and 3 is not particularly limited, but both shoulder portions 2b and 2b of the infusion container 2 are often rounded and obliquely cut at an angle of about 45 °. Therefore, it is preferable to set the inclination angle of the oblique seal portions 3 and 3 to about 45 ° so that both the shoulder portions 2b and 2b can be stably stopped.

  Further, the interval between the upper ends of the oblique seal portions 3 and 3 is not particularly limited, but in order to accommodate from the infusion container with a narrow width to the infusion container with a wide width, the interval between the upper ends of the oblique seal portions 3 and 3 is set. It is preferable to set it to about 1/5 to 2/3 of the width of the outer bag, and depending on the case, the upper end of the oblique seal portions 3 and 3 may not be spaced.

  In the center of the upper portion of the outer packaging bag A, a concave tear guide line 4 that can be teared in one direction for forming an opening that exposes the hook portion 2c of the infusion container 2 has an arc shape (elliptical arc shape) at the lower portion. A V-shaped slit guide line 4 that is concavely bent is formed by oscillating infrared rays with a carbon dioxide gas laser. The tear guide line 4 formed by the carbon dioxide laser is so-called because an inner layer film (linear low-density polyethylene film) described later of the synthetic resin laminate film 1 is not penetrated due to the wavelength of the oscillated infrared rays. This is a half-cut tearing guide line. Therefore, the barrier performance of the exterior bag A is maintained, and transmission of oxygen and moisture can be suppressed. In addition, when the barrier performance of the exterior bag A is not required, it is of course possible to mechanically form the tear guide line 4 along the perforation line.

  As shown in FIG. 1, the tear guide line 4 has a hook portion of the infusion container 2 in a state where the shoulders 2 b and 2 b of the infusion container 2 are centered by the C-shaped oblique seal parts 3 and 3. 2c needs to be formed so as to be inside the tear guide line 4 (upper side in FIG. 1), and when so formed, the synthetic resin laminate film 1 on the upper part of the bag is formed along the tear guide line 4. When the fingertip is torn in one direction, as shown in FIG. 2, the hook portion 2c of the infusion container 2 can be exposed at the tear opening 5 at the top of the bag. Moreover, it is preferable that the opening angle of the V-shaped cutting guide line 4 in which the lower part is bent in an arc shape is about 60 ° to 110 °, and in the case of the cutting guide line 4 of this embodiment, the opening angle is 90 °. It is set. When the opening angle is about 60 ° to 110 °, there is an advantage that the tearability of the tear guide line 4 in one direction is improved. Further, the concave bent portion of the lower part of the tear guide line 4 may be arcuate, elliptical arc or other suitable arc shape, but the lower part is made elliptical like the tear guide line 4 of this embodiment. It is preferable to have a concave curve because there is an advantage that the tearability is further improved.

  The shape of the tear guide line 4 is a concave shape that can be torn in one direction, that is, without being interrupted from one end of the tear guide line 4 to the other end of the tear guide line 4 along the tear guide line 4. If it is a concave shape that can be torn, it is not limited to a V-shape in which the lower portion like the tearing guide line 4 of this embodiment is bent in an arc shape. For example, the infusion container shown in FIG. There is no or a bent part in the middle, such as a semi-elliptical shape like the tearing guide line 41 of the outer bag B, a semi-circular shape, an arc shape, or a U shape with rounded corners at both lower corners. However, various concave shapes having an obtuse angle of 150 ° or more are possible. However, the V-shaped one having the lower portion curved in an arc shape like the cutting guide line 4 of this embodiment is operated along the cutting guide line 4 from one end to the other end of the cutting guide line 4. Can be torn cleanly and smoothly, and can be torn in one direction like other concave shaped tear guide lines, but away from the tear guide line near the last other end of the tear guide line Therefore, it is the most preferable concave shape.

  The infusion container outer bag A shown in FIG. 1 has only one tear guide line 4, but the lower part is recessed in an arc shape like the infusion container outer bag C shown in FIGS. A plurality of bent V-shaped large and small tear guide lines 4a and 4b may be formed at intervals in the vertical direction at the upper center of the outer bag. Similarly, a plurality of semi-elliptical large and small tear guide lines and other concave and large tear guide lines may be formed at intervals. When a plurality of large and small tear guide lines 4a and 4b are formed in this manner, as shown in FIG. 4A, when accommodating an infusion container 21 having a small lateral width, the small tear guide lines 4a The upper portion of the infusion container 21 may be exposed by cutting the upper portion of the bag along the line, and when the infusion container 22 having a large width is accommodated as shown in FIG. Since the upper portion of the bag can be cut along the line 4b to expose the hook portion 2c of the infusion container 22, it is ensured that a tear opening having a size corresponding to the infusion container is formed regardless of whether the infusion container is small or large. The hook portion 2c can be exposed. Needless to say, three or more tear guide lines may be formed at intervals in the upper center of the outer bag A.

  As shown in FIG. 1, notch portions 1e and 1e are formed at both ends of the tear guide line 4 at the upper edge 1a of the outer bag A, and the tear guide is provided from one of the notch portions 1e. A tearing operation in one direction can be easily performed along the line 4 to the other end. Further, notch portions 1f and 1f are also formed near the lower ends of the left and right side edges 1b and 1c of the outer bag A so that the lower portion of the bag can be easily cut and cut from the notches 1f and 1f. It has become. Instead of these notch portions, a simple cut may be made.

  The front and back synthetic resin laminate films 1 constituting the exterior bag A can be used as long as they have light blocking performance, preferably ultraviolet blocking performance and can be heat sealed, and more preferably have barrier performance. A combination is used.

  Examples of the laminate film having ultraviolet blocking performance and heat-sealable include, for example, a polyolefin-based inner layer film (thickness 60 μm) such as linear low-density polyethylene (LLDPE) having good heat sealability, and polyethylene terephthalate ( This is a laminate film in which a polyester-based outer layer film (thickness 12 μm) such as PET) and a polyamide-based intermediate layer film (thickness 15 μm) such as stretched nylon (ONY) are laminated and integrated through an adhesive layer. In addition, an intermediate layer film provided with an ultraviolet absorbing layer (a coating layer or printed layer of a paint or ink containing an ultraviolet absorber) on the inner film side, or an adhesive layer containing an ultraviolet absorber Are preferably used. As the ultraviolet absorber, various known ultraviolet absorbers such as benzophenone, benzotriazole, and triazine can be used.

  Also, polyolefin-based inner layer films (thickness 50 μm) such as linear low density polyethylene (LLDPE), polyamide-based outer layer films (thickness 15 μm) such as stretched nylon (ONY), polyethylene terephthalate (PET), etc. A laminate film obtained by laminating and integrating a polyester-based intermediate layer film (thickness 12 μm) via an adhesive layer, wherein the ultraviolet absorption layer is provided on the surface of the intermediate layer film on the outer layer side. Preferably used.

  In particular, the latter laminated film does not have an ultraviolet absorbing layer on the inner film side of the intermediate film, has a high adhesive strength between the polyester-based intermediate film and the polyolefin-based inner film, and is also polyolefin-based. Since the inner layer film has a thickness as thin as 50 μm, the inner layer film which is originally inferior in tearing property can be easily torn together with the intermediate layer film, and the tear guide line 4 of the outer bag A This is an extremely preferable laminate film because it has the advantage of further improving the tearability along the line.

  In addition, as a laminate film having a light blocking performance, for example, carbon or other black pigments, titanium oxide or other white pigments are included in any or all of the outer layer film, intermediate layer film, and inner layer film so that it is visible. A material that can absorb or reflect a light beam or a material that can selectively block light in a specific wavelength region by containing a specific colored pigment is used.

  On the other hand, as the laminate film having the barrier performance, for example, a metal deposited film such as aluminum is formed on one surface of the intermediate film of the outer film of the former laminated film or the intermediate film of the latter laminated film. Those formed with a transparent metal oxide vapor deposition film such as alumina, silica, etc. are preferably used.

This infusion container outer bag A can be manufactured, for example, by the following method.
That is, the laminate film as a material is folded back so that the outer layer film is on the outside, the upper edge and the left and right side edges are heat-sealed, and the upper and lower sides of the bag are formed in a C shape. Heat seal to form an oblique seal part, and further, carbon dioxide laser processing is performed from above and below to form a tear guide line 4 at the center of the upper part of the bag, and then heat that becomes the upper edge and the left and right side edges By punching the periphery of the seal portion, the infusion container exterior bag A can be mass-produced efficiently.

  The infusion container outer bag A having the above-described configuration is provided in addition to the tear guide line 4 along the tear guide line 4 from the notch portion 1e at one end of the tear guide line 4 with the fingertip at the upper center of the outer bag A. A slit opening 5 can be formed by quickly and smoothly tearing in one direction to the end, and the slit opening 5 is formed in this way. As shown in FIG. The hook part (hook hole) 2c of the infusion container 2 centered on the center line CL of the outer bag with the shoulders 2b and 2b being stopped by the parts 3 and 3 can be cut right and left without shifting. It is exposed from the tear opening 5. Accordingly, the exposed hook portion 2c of the infusion container 2 is hooked on the collar portion 6 of the drip pole as shown in FIG. 2 to suspend the infusion container 2, and the lower end portion of the outer bag A is notched to the notch portion 1f, By cutting or tearing from 1f and connecting the tube 7 for infusion to the infusion outlet 2a of the infusion container 2, preparation for infusion can be performed efficiently. And in the state which suspended the infusion container 2 in this way, since the diagonal seal | sticker parts 3 and 3 formed in the C shape are hooked on both shoulder parts 2b and 2b of the infusion container 2, the exterior bag A is Without dropping off until the drip is finished, the infusion solution in the infusion container 2 can be protected from light such as ultraviolet rays as a protective cover, and alteration of the infusion solution can be prevented.

  The infusion container outer bag B shown in FIG. 3 has an infusion solution shown in FIGS. 1 and 2 except that a semi-elliptical tear guide line 41 is provided as a concave tear guide line that can be torn in one direction. The infusion container outer bag C shown in FIG. 4 has the same configuration as the container outer bag A, and is provided with a plurality of V-shaped tear guide lines 4a and 4b with the lower part bent in an arc shape at intervals. Except for the above, the configuration is the same as that of the infusion container outer bag A shown in FIGS. 1 and 2, and therefore, the same members are denoted by the same reference numerals in FIGS.

  FIG. 5 shows an embodiment of a second infusion container outer bag according to the present invention. The infusion container outer bag D is provided on both sides of the upper part of the outer bag D having light blocking performance. The slanted seal portions 3 and 3 for centering the hook hole 2c of the infusion container 2 on the center line CL of the infusion bag 2 by forming both the shoulder portions 2b and 2b in contact with each other and the upper center of the outer bag D A V-shaped slit guide line 42 with a sharp bottom is formed by a carbon dioxide laser.

  The infusion container outer bag D has a V-shaped tear guide line 42 with a sharp lower part instead of the V-shaped tear guide line 4 whose lower part is cut in one direction. Since it is set as the structure similar to the infusion container exterior bag A shown in FIG. 1, FIG. 2 except having provided, the same code | symbol is attached | subjected to the same member in FIG. 5, and duplication description is abbreviate | omitted.

  Such an infusion container outer bag D must be torn in two directions from both ends of the tear guide line 42 toward the lower end in order to tear it cleanly along the V-shaped tear guide line 42. Although there is no, the hook part 2c of the infusion container 2 is centered by the C-shaped oblique seal parts 3 and 3, and is exposed from the cut opening, so it is hooked on the collar part of the drip pole to prepare for the drip. Can be performed efficiently. And in the state which suspended the infusion container 2, since the diagonal seal | sticker parts 3 and 3 formed in the C shape are hooked on the both shoulder parts of the infusion container, the exterior bag D is dropped until the drip is finished. In addition, the infusion solution inside the infusion container can be protected from light such as ultraviolet rays as a protective cover.

  In this infusion container exterior bag D, a plurality of V-shaped tear guide lines are formed in the upper center of the exterior bag at intervals in the vertical direction, and the tear guide line is selected to define the upper center of the exterior bag. You may comprise so that the opening part of the optimal magnitude | size corresponding to the magnitude | size of the infusion container 2 can be formed by cutting.

6 and 7 show an embodiment of a third infusion container outer bag according to the present invention. The infusion container outer bag E is provided on both sides of the upper portion of the outer bag E having light blocking performance. The slanted seal portions 3 and 3 are formed in a letter C shape for stopping the shoulders 2b and 2b of the container 2 and centering the hook hole 2c of the infusion container 2 on the center line CL of the outer bag. A hook opening (hole) 8 is provided at the center of the upper portion of the container so as to overlap the hook portion (hole) 2c of the centered infusion container 2. As described above, the third infusion container exterior bag E provided with the hook opening 8 in advance has no barrier performance, and is used when accommodating an infusion container filled with an infusion solution that is hardly changed by oxygen or moisture. The
The shape of the hook opening 8 is not limited to the round hole shape, and may be any shape as long as it can be locked to the collar portion 6 of the drip pole. .

In this infusion container outer bag E, the hook opening 8 overlaps with the hook part 2c of the centered infusion container 2 instead of the V-shaped tear guide wire 4 whose lower part is bent in an arc shape. 1 except that the outer bag E is provided at the upper center of the outer bag E. The infusion container outer bag A shown in FIGS. Therefore, duplicate explanation is omitted.

  Even if such an infusion container outer bag E is misaligned, the hook portion 2c of the infusion container 2 and the hook opening 8 provided in the upper center of the outer bag E so as to overlap the hook hole 2c are displaced. By hooking the shoulders 2b, 2b of the infusion container 2 against the C-shaped oblique seal parts 3, 3, the hook part 2c of the infusion container 2 can be easily centered to open the hook opening 8 of the outer bag E. In this manner, the hook part 2c and the hook opening 8 are overlapped and hooked on the collar part 6 of the drip pole, whereby the drip preparation work can be efficiently performed. Thus, since it is not necessary to cut the upper center of the exterior bag E, workability is improved accordingly.
