Description

  The present invention relates to a multi-chamber packaging bag having a plurality of storage portions and a method for manufacturing a package using the multi-chamber packaging bag.

  Conventionally, the split film is sandwiched between the front film and the back film forming the front and back surfaces of the bag by dividing the opening between the front film and the back film into two parts. Each side has a bag shape in which a storage portion is formed, a suction hole (surface side suction hole) for sucking the divided film from the front film side, and a suction hole for sucking the divided film from the back film side (Back side suction hole) is formed in a multi-chamber packaging bag for automatic filling formed on the edge part on the opening side of the front film and the back film, and a manufacturing method of a package using the same. (For example, refer to Patent Document 1).

  More specifically, an article to be packaged is automatically filled by sucking with a suction disk that operates on the front film side and the back film side, respectively, and pulling outward to open each storage unit. The front-side suction hole and the back-side suction hole of the multi-chamber packaging bag are designed to prevent two filling parts from being opened separately at the time of automatic filling and to prevent erroneous filling at the time of automatic filling. is there. For example, the suction disk on the front film side is pressed against the position of the suction hole on the front surface side to suck the divided film, and the suction disk on the back film side is pressed to the position shifted from the suction hole on the back side to suck the back film. When each is pulled outward, the storage part on the back film side can be opened. Contrary to this, the suction film on the front film side is pressed against the position shifted from the suction hole on the front side to suck the front film, and the suction board on the back film side is pressed against the position of the suction hole on the back side to divide. When the film is sucked and pulled outward, the storage portion on the surface film side can be opened.

Japanese Patent No. 3413506

  However, the conventional multi-chamber packaging bag for automatic filling needs to form suction holes in both the front film and the back film in order to selectively open the two storage portions. For this reason, both the suction holes formed in the front film and the suction holes formed in the back film must be adjusted to be in a predetermined position, which increases the number of processes during bag making, such as pitch adjustment of both films. There is. In addition, the suction holes are usually formed in the original film, but the strength of the original film is lowered by the formation of the suction holes, and both the front film and the back film are produced at the time of bag making. There is also a problem that the handleability is lowered.

  Furthermore, after filling the package, the edges on the opening side of both storage parts are sealed by heat fusion, but suction holes are formed in both the front and back films, so sealant material etc. There is a problem that it is easy to adhere and deposit. In addition, the heat fusion is performed so that the suction hole is included in the heat fusion part, but the trace remains as the concave part on both the front and back sides, and there is a problem that the appearance of the obtained package is deteriorated. .

  In the present invention, the suction hole for selectively opening the two storage portions is required only at either one of the front and back sides, and it is necessary to adjust the pitch between the front and back films, and at the time of bag making accompanying the formation of the suction holes. The purpose is to alleviate the deterioration of the handling due to the anti-film, the adhesion and deposition of the sealant material on the seal bar, and the deterioration of the appearance due to the traces of the suction holes left in the heat-sealing part for sealing. .

In order to achieve the above object, the present invention bisects the opening between one film and the other film between one film located on either side of the front and the other film located on the other side. The split film is sandwiched, and the left and right side edges of one film, the split film, and the other film are overlapped and joined at the side edge fusion part, so that one film side is separated from the split film. And the other film side, each of which has a bag shape with a storage part formed,
In one or both of the left and right side edge fused portions, at least part of the opening side, one film from the three-layer fused portion joining the three of the one film, the divided film, and the other film. And the two-layer fusion part joining the two of the divided films enter the inside of the bag, at least in part of the opening side, compared to the opening width of the storage part on the one film side The opening width of the storage part on the other film side is widened,
Of one film a split film and other film, only the other film, and characterized in that the edge of the opening side, the suction hole for sucking the split film from the other film side is formed A multi-chamber packaging bag for automatic filling is provided.

In the present invention, a split film is sandwiched between one film located on either side of the front and the other film and the other film located on the other side by dividing the opening between the one film and the other film, The right and left side edges of the film, the split film and the other film are overlapped and joined at the side edge fusion part, so that the split film is the boundary, and one film side and the other film side, respectively. A bag with a storage part is formed,
In one or both of the left and right side edge fused portions, from the three-layer fused portion joining the three of the one film, the divided film and the other film over the entire length, the one film and the divided film Since the two-layer fusion part joining the two members enters the inside of the bag, the opening width of the storage part on the other film side is wider than the opening width of the storage part on the one film side. As well as
Of the one film, the divided film, and the other film, only the other film is formed with suction holes for sucking the divided film from the other film side at the edge on the opening side. It also provides a multi-chamber packaging bag for automatic filling.

Moreover, the present invention uses the above-described multi-chamber packaging bag for automatic filling,
The edge of one film and the other film on the opening side is sucked with a suction disk facing the one film and a suction disk facing the other film, respectively, and pulled outward, so that the other film side A process of opening only the storage part and filling a packaged item,
While sucking the edge on the opening side of one film with the suction disk facing the one film, the suction disk facing the other film through the suction hole at the edge on the opening side of the divided film And a method of manufacturing a package, characterized by having a step of opening only the storage part on one film side and filling the packaged object by pulling outward and pulling outward respectively. is there.

  The manufacturing method of the packaging body of the present invention described above is to fill the package in the other film-side storage part and one film-side storage part, and then fuse the edge part on the opening side to form the suction hole. It is preferable to form a single through hole including a suction hole as a hanging hole in the sealed fused part after forming the encapsulated sealed fused part.

  In addition, in the manufacturing method of the package according to the present invention, the step of opening the other film-side storage portion and filling the object to be packaged, and the one film-side storage portion being opened and filling the object to be packaged It is sufficient to select which of the processes is performed first according to the package. In the method for manufacturing a package according to the present invention, having both the above steps means that at least both steps are performed, and the order thereof is not limited.

  According to the present invention, the storage part on one film side sucks the edge part on the opening part side of one film, and the edge part on the opening part side of the divided film from the other film side via the suction hole. It can be released by sucking and pulling.

  On the other hand, the opening on the other film side can be opened by sucking and pulling the edge on the opening side of one film and the edge on the opening side of the other film. The opening on the other film side is performed in a state where the divided film is not sucked to either side. However, the opening width of the other film-side storage portion is wider than the opening width of one film side, and the other film-side storage portion is easier to open than the one film-side storage portion. It is possible to preferentially open the storage part on the other film side without opening the storage part on the one film side.

  As described above, according to the present invention, by providing the suction hole only on the other film side, the storage part on one film side and the storage part on the other film side can be selectively opened. Therefore, it takes time and effort to adjust the pitch of both the front and back films, a decrease in handling properties of the original film due to the formation of suction holes, the adhesion and deposition of the sealant material on the seal bar, and the heat-sealing part for sealing. Any deterioration in the appearance due to the traces of the suction holes can be reduced by half compared to the conventional case where two suction holes are required.

  Hereinafter, the present invention will be further described with reference to the drawings. In addition, in drawing demonstrated below, the same code | symbol shows the same member or site | part.

  First, based on FIGS. 1-8, an example of the manufacturing method of the multi-chamber packaging bag which concerns on the 1st example of this invention, and the package of this invention using this is demonstrated.

  FIG. 1 is an explanatory view of a combined state of films constituting the multi-chamber packaging bag according to the first example of the present invention, FIG. 2 is a perspective view of the multi-chamber packaging bag according to the first example of the present invention, and FIG. The perspective view of the state which set the multi-chamber packaging bag which concerns on the 1st example of this invention to the holding | gripping tool, FIG. 4 is shown to the accommodating part of the other film side of the multi-chamber packaging bag which concerns on the 1st example of this invention. FIG. 5 is an explanatory view when filling an object to be packaged, FIG. 5 is an explanatory view of an action when the other film side storage portion of the multi-chamber packaging bag according to the first example of the present invention is opened, and FIG. FIG. 7 is a plan view showing an example of a manufactured package, and FIG. 8 is a manufactured package. FIG. 7 is an explanatory view of a multi-chamber packaging bag according to an example of FIG. It is a top view which shows the other example of a body.

  As shown in FIG. 1 and FIG. 2, the multi-chamber packaging bag 4 of this example is composed of three films: one film 1, a divided film 2, and the other film 3. One film 1 and the other film 3 are located on the front and back sides of the multi-chamber packaging bag 4, which may be either the front surface or the back surface, but for convenience of explanation, the one film 1 is located on the front surface side of the bag. A film and the other film 3 are demonstrated as a back film located in the back surface side of a bag.

  The surface film 1, the split film 2, and the back film 3 in this example are the same shape and the same size composed of the same type of film. The multi-chamber packaging bag 4 has the surface film 1, the divided film 2, and the back film 3 stacked with the divided film 2 sandwiched between the surface film 1 and the back film 3, leaving an opening 7 that is divided by the divided film 2. Thus, it forms a bag shape in which three sides of the overlapped peripheral edge portions are heat-sealed. Reference numerals 5 and 5 denote left and right side edge fusion portions, and reference numeral 6 denotes a bottom edge fusion portion.

  The divided film 2 bisects the opening 7 between the front film 1 and the back film 3 formed at one edge where the heat fusion is not performed, and the divided film 2 serves as a boundary for the surface film. Storage portions 9a and 9b are formed on the 1 side and the back film 3 side, respectively. The storage portions 9a and 9b have openings 7a and 7b, which are one and the other of the openings 7 divided into two parts by the divided film 2, respectively. At the center of the edge of the back film 3 on the opening 7 (7b) side, a suction hole 8 penetrating only through the back film 3 is formed so that the split film 2 can be sucked from the back film 3 side. Has been.

  By the way, the side edge fusion parts 5 and 5 are the three-layer fusion parts 5b and 5b obtained by joining the surface film 1, the divided film 2 and the back film 3, and the surface film 1 and the divided film 2. It is comprised by the two-layer melt | fusion part 5a, 5a which joined. And the multi-chamber packaging bag 4 of this example is such that the two-layer fused portions 5a, 5a are inside the bag from the three-layer fused portions 5b, 5b over the entire length at the left and right side edge fused portions 5, 5. I'm stuck in. As a result, the opening width of the storage portion 9b on the back film 3 side is wider than the opening width of the storage portion 9a on the front film 1 side. With such an opening width, as will be described later, when opening the storage portion 9b on the back film 3 side, the storage portion on the surface film 1 side can be used without sucking the divided film 2 from the surface film 1 side. The storage portion 9b on the back film 3 side can be preferentially opened without opening 9a.

  In this example, in the left and right side edge fused portions 5 and 5, the two-layer fused portions 5a and 5a enter the inside of the bag from the three-layer fused portions 5b and 5b. Only in the bonding part 5, the two-layer fusion part 5a may enter the inside of the bag from the three-layer fusion part 5b.

  As the front film 1, the split film 2, and the back film 3 constituting the multi-chamber packaging bag 4 of the present invention, a single layer or a laminated film of a synthetic resin can be used. As a laminated film, in addition to a laminate of synthetic resin layers, a laminate of a synthetic resin layer and a metal or other inorganic layer or a paper layer may be used.

  The multi-chamber packaging bag 4 of this example is obtained by stacking the surface film 1 and the divided film 2, the two-layer fusion portions 5 a and 5 a, and the three-layer fusion portions 5 b and 5 b adjacent to the two-layer fusion portions 5 a and 5 a. After heat-sealing a part of the film or a part corresponding to the whole of the three-layer fusion part 5b, 5b, the back film 3 is further overlapped, and a region corresponding to the three-layer fusion part 5b, 5b is thermally fused. It can be manufactured easily.

  The multi-chamber packaging bag 4 includes a storage portion 9a on the surface film 1 side formed between the surface film 1 and the split film 2, and a storage portion 9b on the back film 3 side formed between the back film 3 and the split film 2. And can be filled with two types of articles to be packaged. The package is automatically opened without opening the storage portion 9a on the front film 1 side and the storage portion 9b on the back film 3 side separately (opening portions 7a and 7b are opened separately) without mistakes in the filling location. Can be filled.

  Next, an example of a method for manufacturing a package using the multi-chamber packaging bag 4 will be described.

  The packaging body using the multi-chamber packaging bag 4 can be produced by holding the multi-chamber packaging body 4 in a state where the multi-chamber packaging body 4 is erected with gripping tools 11 and 11 as shown in FIG. 3, for example.

  First, as shown in FIG. 3, the multi-chamber packaging bag 4 is suspended by gripping the upper portions of the left and right side edge fused portions 5, 5 with the gripping tools 11, 11, and the surface film 1 and the back film 3. It is located between a pair of suction disks 10a and 10b that can advance and retract toward the outer surface. As the gripping tools 11, 11, clip-shaped ones that sandwich and hold the left and right side edge fused portions 5, 5 can be used. In addition, the gripping tools 11 and 11 are elastic in the opposing direction so that the storage portions 9a and 9b can be opened largely and an excessive force is not applied to the multi-chamber packaging bag 4 due to the opening. It is preferable to be able to advance and retreat.

  The selective opening of the storage portion 9a (see FIG. 2) on the front film 1 side and the storage portion 9b (see FIG. 2) on the back film 3 side is performed by advancing and retracting the suction disks 10a and 10b. Although the suction position by the suction disks 10a and 10b will be described later, the adjustment of the suction position can be performed by adjusting the position of the multi-chamber packaging bag 4 between the suction disks 10a and 10b. However, in order to facilitate the adjustment of the suction position, the suction disks 10a and 10b are preferably movable up and down and left and right along the opposing front film 1 or back film 3.

  A method for opening the storage portion 9b on the back film 3 side and filling the article to be packaged will be described.

  As shown in FIG. 4, both suction discs 10 a and 10 b are advanced toward the front film 1 and the back film 3, and the central portion of the edge on the opening 7 side of the front film 1 and the back film 3 The suction is performed by contacting each edge of the opening 6 that is displaced from the suction hole 8. With the front film 1 and the back film 3 being adsorbed by the suction disks 10a and 10b, the suction disks 10a and 10b are moved backward. Thereby, the surface film 1 and the back film 3 are pulled outward, and are each curved outward and convex.

  By the way, as described above, since the opening width of the storage portion 9b on the back film 3 side is wider than the storage portion 9a on the front film 1 side (see FIG. 2) and is easily opened, the back film 3 Is curved away from the divided film 2 so as to protrude outward, and the storage portion 9b on the back film 3 side is opened. Further, since the opening width of the storage portion 9a on the front film 1 side is narrower than the storage portion 9b on the back film 3 side and is difficult to be opened, even if the storage portion 9b on the back film 3 side is opened. The storage portion 9a on the surface film side is kept open without being opened. Therefore, only the storage portion 9b on the back film 3 side is opened, and the packaged product can be surely automatically filled into the storage portion 9b on the back film 3 side while preventing erroneous insertion.

  In particular, as shown in FIG. 5, when the two-layer fused portions 5 a and 5 a have entered the inside of the bag from the three-layer fused portions 5 b and 5 b in the left and right side edge fused portions 5 and 5 as in this example. As described above, by pulling the surface film 1 outward, a force F that pulls the divided film 2 in the same direction as the surface film 1 acts on the inner end portions of the two-layer fused portions 5a and 5a. For this reason, the division | segmentation film 2 follows the surface film 1, and curves to the surface film 1 side convexly, and the accommodating part 9a (refer FIG. 2) by the side of the surface film 1 remains in the closed state.

  The amount of the two-layer fusion part 5a, 5a entering the inside of the bag from the three-layer fusion part 5b, 5b makes a difference in the ease of opening between the storage parts 9a, 9b and makes the force F easy to act. Therefore, it is preferably 1 mm or more, particularly preferably 2 to 5 mm. The upper limit differs depending on the size of the bag, but is generally up to 20 mm.

  When the suction plates 10a and 10b are retracted and the front film 1 and the back film 3 are pulled outward to open the storage part 9b on the back film 3 side, the gripping tools 11 and 11 are elastically advanced in the opposite direction. Then, excessive tension is prevented from acting on the multi-chamber packaging bag 4. As described above, after the storage portion 9b on the back film 3 side is filled with the article to be packaged, when both suction disks 10a and 10b are advanced, both gripping tools 11 and 11 are elastically retracted. The opening 7b of the storage portion 9b returns to the closed state.

  Next, a method for selectively opening the storage portion 9a (see FIG. 2) on the surface film 1 side will be described.

  As shown in FIG. 6, the suction disks 10a and 10b are brought into contact with the central portion of the edge on the opening 7 side of the front film 1 and the suction hole 8 portion of the back film 3, respectively, and sucked, The surface film 1 is adsorbed by the suction disk 10a, and the divided film 2 is adsorbed by the suction disk 10b through the suction hole 8. When the suction disks 10a and 10b are retracted in this state, as shown in FIG. 6, the surface film 1 is pulled outward, and the split film 2 is pulled outward together with the back film 3, so that the surface film The opening 7a of the storage part 9a on the 1 side is widened. At this time, since the divided film 2 is adsorbed to the suction disk 10b through the suction hole 8, the divided film 2 and the back film 3 are in close contact with each other, and the storage portion 9b on the back film 3 side (see FIG. 2). The opening 7b is closed. Therefore, only the storage portion 9a on the surface film 1 side is opened, and an object to be packaged can be automatically filled into the storage portion 9a on the surface film 1 side reliably while preventing erroneous insertion.

  When the suction films 10a and 10b are retracted and the front film 1, the split film 2 and the back film 3 are pulled outward to open the storage portion 8a on the front film 1 side, the gripping tools 11 and 11 are elastic. Accordingly, the multi-chamber packaging bag 4 is prevented from excessive tension. When the storage portion 9a on the surface film 1 side is filled with an object to be packaged as described above, when both suction discs 10a and 10b are advanced, both gripping tools 11 and 11 are elastically retracted. The opening 7a of the storage portion 9a returns to the closed state.

  As described above, the corresponding packaged items are automatically filled in the storage part 9a on the front film 1 side and the storage part 9b on the back film 3 side, respectively, and then the edge part on the opening part 7 side is heat-sealed. Then, as shown in FIG. 7, a sealed fusion part 12 that encloses the suction hole 8 is formed, and the opening 7 is sealed to complete the production of the package. The heat sealing of the edge portion on the opening 7 side is performed by sandwiching the edge portion on the opening portion 7 side with a seal bar in a state where the multi-chamber packaging bag 4 containing the article to be packaged is suspended by the gripping tools 11 and 11. Can be done.

  By the way, in the package shown in FIG. 7, the trace of the suction hole 8 remains in the sealed fusion part 12 as a recess, although only on the back film 3 side. Therefore, as shown in FIG. 8, after forming the sealing fused portion 12, the suction hole 8 portion is punched out to form a single through hole including the suction hole 8 as the hanging hole 13. preferable. This suspension hole 13 is for hanging and displaying the manufactured package at a shop front. By removing the trace of the suction hole 8 with this suspension hole 13, the uncomfortable feeling can be eliminated. The suspension hole 13 is formed as a through-hole that is the same as or larger than the suction hole 8, and has an elliptical shape, a gourd shape, an egg shape, a rice ball shape, etc. in addition to the circular hole shown in the figure. You can also.

  In the above description, the packing material is filled in the storage portion 9b on the back film 3 side and the packing material is filled in the storage portion 9a on the surface film 1 side, but on the contrary, It can also carry out in the order of filling of the article to be packaged in the storage section 9a on the front film 1 side and filling of the article to be packaged in the storage section 9b on the back film 3 side. Moreover, although the method using the holding tools 11 and 11 was demonstrated, it can also carry out without using the holding tools 11 and 11. For example, the suction disk 10a on the surface film 1 side is fixed at a fixed position, the edge on the opening 7 side of the surface film 1 is adsorbed to the suction disk 10a, and the multi-chamber packaging bag 4 is held upright, The storage unit 9a, 9b can also be selected by moving the suction disk 10b on the back film 3 side forward and backward by changing the suction position and pulling only the back film 3 or both the back film 3 and the split film 2 outward. Thus, the package can be manufactured by filling the article to be packaged while being opened.

  Next, based on FIG. 9, the multi-chamber packaging bag which concerns on the 2nd example of this invention is demonstrated.

  FIG. 9 is a perspective view of a multi-chamber packaging bag according to a second example of the present invention.

  As shown in FIG. 9, the multi-chamber packaging bag 4 of the present example is basically the same as the multi-chamber packaging bag 4 according to the first example described above, but the two-layer fused portions 5a and 5a are The portion of the inner side of the bag that enters the inner side of the three-layer fused portions 5b and 5b does not extend over the entire length of the side edge fused portions 5 and 5, but the opening 7 side of the side edge fused portions 5 and 5 It is only a part of. In particular, if the two-layer fusion parts 5a and 5a that protrude beyond the three-layer fusion parts 5b and 5b are provided within the range where the sealing fusion part 12 shown in FIGS. After stopping, the presence of the two-layer fused portions 5a, 5a is not known. Further, when the storage portions 9a and 9b of the multi-chamber packaging bag 4 of this example are opened by the suction plates 10a and 10b as described in FIGS. 4 and 6, the suction plate 10a on the surface film 1 side is In order to facilitate the application of the force F described in 5, it is preferable to suck the region between the two-layer fused portions 5a and 5a.

  In this example, the two-layer fused portions 5a, 5a are formed on both the left and right side edge fused portions 5, 5, but are formed only on either one of the side edge fused portions 5. You can also. In addition, a space is provided between the two-layer fused portions 5a and 5a and the opening 7 (7a) in this example, but the two-layer fused portion continuous from the opening 7a without any gap. In addition, it is possible to widen an area where it is preferable to perform suction with the suction board 10a.

  Next, based on FIG. 10, a multi-room packaging bag according to a third example of the present invention will be described.

  FIG. 10 is a perspective view of a multi-chamber packaging bag according to a third example of the present invention.

  As shown in FIG. 10, the multi-chamber packaging bag 4 of this example is basically the same as the multi-chamber packaging bag 4 according to the first example described above, but the front film 1 is divided into the back film 3 and the divided film. It is shorter than film 2. In the side edge seal portion 5, the lower two-layer fused portion 5 x joins the back side film 3 and the divided film 2, and in the bottom edge seal portion 6, the lower two-layer fused portion. The part 6x joins the back film 3 and the split film 2, and the middle two-layer fusion part 6y joins the surface film 1 and the split film 2.

  In the multi-chamber packaging bag 4 of this example, since the front film 1 is shorter than the back film 3 and the split film 2, the depth of the storage part 9a on the back film 3 side is deep, and the storage part 9b on the front film 1 side is deep. The depth is shallow. For this reason, it can respond to the case where the quantity of the package to be stored in the storage unit 9a is small or small compared to the package to be stored in the storage unit 9b.

  In the present invention, the storage portion 9a is sandwiched between the surface film 1 and the split film 2 and / or between the back film 3 and the split film outside the bag having the storage portions 9a and 9b having different sizes. And / or 9b can also be applied to a multi-chamber packaging bag having a gusset-type bag shape.

Example 1
A laminated film with a layer structure of LL (40 μm) / PET (12 μm) / Al (9 μm) / LL (40 μm). After the part was heat-sealed with a width of 10 mm, another sheet of the same film was placed in a horizontally long shape and the left and right short side edges were heat-sealed with a width of 9 mm to create a cylindrical simulated multi-chamber packaging bag. . That is, a simulated multi-chamber packaging bag was created in which the two-layer fused portion at the side edge fused portion entered the inside of the bag by 1 mm from the three-layer fused portion.

  The simulated multi-chamber packaging bag was manually positioned between a pair of suction plates with the unsealed edge portion in the vertical direction, and both suction plates were advanced and adsorbed on the front and back surfaces, respectively. The suction position by the suction disk was set to a position approximately 5 mm below the upper edge at both the left and right central parts of the upper unsealed edge.

  The operation of observing the open state of the storage part was repeated five times by releasing the hands after adsorbing to the simulated multi-chamber packaging bag suction board and moving both suction boards backward. The results are shown in Table 1. In Table 1, the amount of protrusion of the two-layer fusion part from the three-layer fusion part is “seal width difference”, the storage part with a small opening width is “first chamber”, and the storage part with a large opening width is “ The second room.

Example 2
The same two films as in Example 1 were stacked horizontally and heat-sealed at the short side edges of the left and right sides with a width of 20 mm, and then the other same film was also stacked horizontally and stacked on the left and right short sides. The edge was heat-sealed with a width of 10 mm to create a cylindrical simulated multi-chamber packaging bag. That is, a simulated multi-chamber packaging bag was created in which the two-layer fused portion at the side edge fused portion entered the inside of the bag by 10 mm from the three-layer fused portion.

  About the said simulation multiple bag, it carried out similarly to Example 1, and observed the opening state of the accommodating part. The results are shown in Table 1.

Comparative Example 1
Three sheets of the same film as in Example 1 were stacked horizontally, and the left and right short side edges were heat-sealed with a width of 10 mm to produce a cylindrical simulated multi-chamber packaging bag. That is, a simulated multi-chamber packaging bag having no two-layer fusion part protruding from the three-layer fusion part at the side edge fusion part to the inside of the bag was prepared.

  About the said simulation multiple bag, it carried out similarly to Example 1, and observed the opening state of the accommodating part. The results are shown in Table 1.
