It is arranged at a position along BL (FIG. 7). In other words, the local joint 29 is arranged near the boundary line BL. The distance between the position of the local joint 29 and the boundary line BL is preferably within 30 mm, more preferably within 15 mm.
As a result, in the container body 20, the bending deformability in the portion along the boundary line BL (or the portion in the vicinity thereof) can be appropriately secured, so that the structure in which the handle portion 12 is bent in a desired direction with respect to the body portion 11 can be obtained. realizable. Moreover, since the continuity between the first portion and the third portion can be sufficiently ensured, the mechanical strength of the portion of the container body 20 where the first portion and the third portion are formed can be sufficiently ensured. .

In the case of this embodiment, the opposing portion 67a is formed to have a larger diameter than the vertically extending filling portion 66 of the body portion. This further improves the shape retention of the body portion 11 when the user grips the handle portion 12 to hold the container 100 .
More specifically, the upwardly extending portion 67b is formed to have a larger diameter than the body vertically extending filling portion 66, and the inclined filling portion 65 is formed to have a larger diameter than the inclined filling portion 64. As shown in FIG. These structures also improve the shape retention of the body portion 11 when the user grips the handle portion 12 to hold the container 100, and the body portion vertically extending filling portion 66 and the inclined filling portion 64 are further improved. By reducing the diameter, the volume of the inner bag 40 can be increased, and the filling amount of the contents can be increased. .

In addition, since the vertically extending filling portion 67 of the body portion has the upwardly extending portion 67 b extending upward from the communicating portion between the vertically extending filling portion 67 of the body portion and the cross filling portion 69 , the communication in the body portion 11 is The shape retention is improved in the portion above the part. Therefore, it is possible to store the contents 18 to a higher position within the storage area 17 inside the body portion 11 .

In the case of this embodiment, the container 100 includes an outside air introducing portion 73 (FIGS. 1 and 8) that introduces outside air between the outer surface of the inner bag 40 (inner container) and the inner surface of the container body 20 .
As shown in FIG. 8 , the outside air introduction portion 73 is formed by, for example, a gap between a portion of the body portion 11 facing the through portion 19 and a portion of the inner bag 40 facing the through portion 19 . Of course, the installation position of the outside air introduction part 73 may be formed anywhere as long as outside air can be introduced.
Since the container 100 is provided with the outside air introduction part 73, the inner bag 40 can be easily shrunk independently of the container body 20 when the contents 18 are discharged from the container 100. improves the excretion of

As shown in FIG. 2 , the container 100 includes a main body forming sheet material 21 forming a container main body 20 and an inner bag forming sheet material 41 forming an inner bag 40 .
As shown in FIG. 9, the body-constituting sheet material 21 is formed by mutually laminating and joining an outer film 22 that forms the outer surface side of the container body 20 and an inner film 23 that forms the inner surface side of the container body 20. It is composed of That is, as an example, in the case of the present embodiment, the body-constituting sheet material 21 is composed of two film layers, an outer film 22 and an inner film 23 . However, the present invention is not limited to this example, and the body-constituting sheet material 21 may have film layers other than the outer film 22 and the inner film 23 .
The body-constituting sheet material 21 is formed with a non-bonded portion 24 in which the outer film 22 and the inner film 23 are partially non-bonded. For example, in one or both of the outer film 22 and the inner film 23, the surface facing the other is partially non-bonded. The non-bonding treatment can be easily formed by applying a non-bonding agent (so-called desizing agent) to create a desizing state. Any antisizing agent can be used as long as it can prevent the bonding of the outer film 22 and the inner film 23 . As the desizing agent, for example, printing inks, medium inks, desizing inks, and the like used in offset printing, flexographic printing, and letterpress printing (relief printing) can be preferably used. In addition, thermosetting and UV-curable inks can be preferably used.
The non-joining portion 24 is the range to which the non-joining treatment has been applied. A filling portion 60 is formed by enclosing a filling material in the non-bonded portion 24 .
The filling portion 60 is not necessarily formed in the entire non-joint portion 24 , and may be formed in a part of the plurality of non-joint portions 24 .
The entire surface of the inner film 23, except for the non-bonded portion 24, preferably has a bonded portion bonded to one surface of the outer film 22, which is the case in this embodiment.
As a technique for bonding the outer film 22 and the inner film 23, heat sealing, ultrasonic sealing, bonding with an adhesive, or the like can be used as an example.
In addition, for example, at the stage where the main body constituting sheet material 21 is formed, a local joint portion 29 is formed in which the outer film 22 and the inner film 23 are locally joined. As for the method of forming the local joint portion 29, in addition to the same method as that for joining the outer film 22 and the inner film 23 described above, a method effective for joining in a minute area such as an ultrasonic spot welder or an adhesive seal can be used. .

Each of the outer film 22 and the inner film 23 also has a multi-layer structure. The inner bag-constituting sheet material 41 also has a multi-layer structure.

The outer film 22 has, for example, a four-layer structure in which a first layer, a second layer, a third layer and a fourth layer are laminated in this order.
Among them, the first layer is made of, for example, polyethylene terephthalate (PET) or oriented nylon (ONy). The primary function of the first layer is to provide the container body 20 with glossiness and printability and to ensure the rigidity of the container body 20 .
The second layer is, for example, a layer of transparent vapor-deposited PET made of polyethylene terephthalate in which silica and/or alumina is vapor-deposited on the surface of the second layer on the first layer side. A main function of the second layer is to provide gas barrier properties to the container body 20 .
The third layer is made of stretched nylon, for example. A main function of the third layer is to ensure pinhole resistance of the container body 20 .
The fourth layer is made of, for example, linear low density polyethylene (LLDPE). The main function of the fourth layer is to secure heat sealability with the inner film 23 , heat sealability between the outer films 22 , and heat sealability with the inner bag-constituting sheet material 41 .

As the layer structure of the inner film 23, a layer structure similar to that of the outer film 22 can be adopted. However, the material of each layer constituting the outer film 22 and the inner film 23 is not limited to the above examples. Also, the inner film 23 may have a layer structure different from that of the outer film 22 .

The body-constituting sheet material 21 comprises, for example, a first sheet portion 31 that constitutes the first main surface portion 20a, a second sheet portion 32 that constitutes the second main surface portion 20b, and a bottom gusset 13. A bottom gusset-constituting sheet portion 38 that is a portion that forms a bottom gusset, a first handle-constituting sheet portion 33 that constitutes the front side of the handle portion 12, and a second handle-constituting sheet that constitutes the back side of the handle portion 12. a top gusset-constituting sheet portion 39 that constitutes the top gusset 14; and a tubular extending portion 25. The extending portion 25 extends outward from the second handle-constituting sheet portion 34, for example.
Penetration portions 19 and corresponding penetration portions 35 are formed between the first sheet portion 31 and the first handle-constituting sheet portion 33 and between the second sheet portion 32 and the second handle-constituting sheet portion 34, respectively. It is
The top gusset-constituting sheet portion 39 is formed with an insertion hole 21a through which the ejection cylinder portion 15a of the spout 15 is inserted.
A portion of the body-constituting sheet material 21 excluding the top gusset-constituting sheet portion 39 and the extension portion 25 is referred to as a sheet body portion 28 .
In the case of this embodiment, the non-joint portion 24 is formed in a shape corresponding to the shape of the filling portion 60 of the container 100 . The non-joint portion 24 communicates with the outside, for example, only at the open end 24a at the tip of the extending portion 25 .

The periphery of the portion of the outer film 22 that constitutes the sheet body portion 28 includes, for example, a portion adjacent to the penetration portion 35 in the first sheet portion 31, a portion adjacent to the penetration portion 35 in the second sheet portion 32, and a second sheet portion 32. Exposed portions 26 are not covered with the inner film 23 except for portions corresponding to the base ends of the extending portions 25 in the two-handle-constituting sheet portion 34 .
In the case of this embodiment, the top gusset-constituting sheet portion 39 as a whole is composed of, for example, the outer film 22 and does not include the inner film 23 . Therefore, the entire portion of the outer film 22 that constitutes the top gusset-forming sheet portion 39 is an exposed portion 26 that is not covered with the inner film 23 . However, the present invention is not limited to this example, and the top gusset-constituting sheet portion 39 may also have a laminated structure of the outer film 22 and the inner film 23 .
In the extending portion 25, the outline of the outer film 22 and the outline of the inner film 23 match each other in plan view.
The exposed portion 26 serves as a joining portion (inner/outer sealing portion 43) between the main body forming sheet material 21 and the inner bag forming sheet material 41, and a joining portion (main body sealing portion 48) between the main body forming sheet members 21. FIG.

The inner bag forming sheet material 41 forming the inner bag 40 has, for example, a three-layer structure formed by laminating a first layer, a second layer and a third layer in this order.
Among them, the first layer is made of, for example, linear low-density polyethylene. A main function of the first layer is to ensure heat-sealing properties with the main body-constituting sheet material 21 (heat-sealing properties with the outer film 22).
The second layer is, for example, a layer of transparent vapor-deposited stretched nylon composed of stretched nylon in which silica and/or alumina is vapor-deposited on the surface of the second layer on the first layer side. Main functions of the second layer include ensuring gas barrier properties and pinhole resistance.
The third layer is made of, for example, linear low-density polyethylene. A main function of the third layer is to secure the heat-sealing property between the inner bag-constituting sheet materials 41 .
Note that the layer structure of the inner bag-constituting sheet material 41 is not limited to the structure described here.

As shown in FIG. 10 , the inner bag-constituting sheet material 41 is laminated on the main body-constituting sheet material 21 , and the exposed portion 26 of the outer film 22 and the peripheral edge portion of the inner bag-constituting sheet material 41 are joined to each other to form an inner and outer shell. By forming the sealing portion 43 (see FIG. 2), the container-constituting sheet material 51 is constituted by the main body-constituting sheet material 21 and the inner bag-constituting sheet material 41 .
In the case of this embodiment, the inner bag-constituting sheet material 41 includes a portion having the same shape as the first sheet portion 31, a portion having the same shape as the second sheet portion 32, a portion having the same shape as the bottom gusset-constituting sheet portion 38, and a top gusset. It has portions of the same shape as the constituent sheet portion 39, and these portions are superimposed on the first sheet portion 31, the second sheet portion 32, the bottom gusset constituent sheet portion 38, and the top gusset constituent sheet portion 39, respectively. ing. The inner bag-constituting sheet material 41 further has a portion that is one size smaller than the first handle-constituting sheet portion 33 and a portion that is one size smaller than the second handle-constituting sheet portion 34 . are superimposed on the first handle-constituting sheet portion 33 and the second handle-constituting sheet portion 34, respectively.
Through-holes 45 that are one size larger than the through-holes 35 are formed in the inner bag-constituting sheet material 41 at portions corresponding to the through-holes 35 .
In FIG. 10, the seal boundary line 41a of the inner bag-constituting sheet material 41 constituting the inner bag 40 is indicated by a solid line for the sake of convenience. The seal boundary line 41a is a region where the inner bag-constituting sheet members 41 are joined (sealed) to each other when the container 100 is formed using the container-constituting sheet members 51, and another region of the inner bag-constituting sheet member 41. and the boundary between

An insertion hole 41b through which the pouring tube portion 15a of the spout 15 is inserted is formed in a portion of the inner bag-constituting sheet material 41 that overlaps the top gusset-constituting sheet portion 39. As shown in FIG.
The plate-like portion 15 b of the spout 15 is provided, for example, on the inner surface of a portion of the inner bag-constituting sheet material 41 that overlaps the top gusset-constituting sheet portion 39 . The pouring tube portion 15a protrudes through the insertion hole 41b of the inner bag-constituting sheet material 41 and the insertion hole 21a of the top gusset-constituting sheet portion 39 to the outer surface side of these sheets.

The container-constituting sheet material 51 is valley-folded along the folding lines 81, 82, and 84 shown in FIG. are joined together, the container-constituting sheet material 51 is formed into a bag-like double structure. 10. Here, the valley fold is a way of folding convexly toward the back side in FIG. 10, and the mountain fold is a way of folding convexly toward the front side in FIG.
That is, the inner bag 40 is formed by the inner bag-constituting sheet material 41 by joining the edges of the inner bag-constituting sheet material 41 to form the inner bag sealing portion 42 (see FIG. 2). In addition, in the body-constituting sheet material 21, the outer films 22 are joined to each other in the portion constituting the bottom portion of the container body 20 and the portion constituting the handle portion 12, respectively, so that the body sealing portion 48 (see FIG. 2) is formed. By forming, the body-constituting sheet material 21 is formed into a bag shape.
As methods for joining the inner bag-constituting sheet materials 41 together and joining the outer films 22 together, for example, heat sealing, ultrasonic sealing, bonding with an adhesive, or the like can be used.

After the container-constituting sheet material 51 is formed in the shape of a double bag, the filler is injected from the open end 24a of the extending portion 25 into the non-joining portion 24, and is connected to the base end side of the extending portion 25, for example. The non-bonded portion 24 is sealed at the site. As a result, the filling material is enclosed in the non-bonded portion 24 to form the filling portion 60 . Although the pressure inside the filling part 60 is not particularly limited, it is preferably higher than the atmospheric pressure, and can be, for example, 10 kPa or more and 500 kPa or less (gauge pressure). After forming the filling portion 60, for example, the extending portion 25 is cut off.
Thus, the container 100 is obtained. However, the extending portion 25 may remain even in the state of the container 100 .

After the container 100 is manufactured, the contents 18 are filled in the containing area 17 through the ejection tube portion 15a of the spout 15, and then the contents 18 are enclosed in the containing area 17 by attaching the cap 16 to the spout 15. A filled container 200 is obtained.

In this manner, the body portion 11 has the first main surface portion 20a and the second main surface portion 20b facing each other with the accommodation area 17 interposed therebetween, and the body-constituting sheet material 21 has the first main surface portion 20a. A first sheet portion 31 that constitutes a part, a second sheet portion 32 that constitutes the second main surface portion 20b, a first handle-constituting sheet portion 33 that is continuous with the first sheet portion 31, and a second sheet portion 32 that is continuous The first handle-constituting sheet portion 33 and the second handle-constituting sheet portion 34 extend in the facing direction (front-rear direction) between the first main surface portion 20a and the second main surface portion 20b. are overlapped on each other to form the handle portion 12 .
Further, a first filling portion 61 is formed in each of the first sheet portion 31 and the second sheet portion 32, and a second filling portion 61 is formed in each of the first handle-constituting sheet portion 33 and the second handle-constituting sheet portion 34. A portion 62 is formed.
The container body 20 has a first communication portion where a first filling portion 61 formed in the first sheet portion 31 and a communication filling portion in a second filling portion 62 formed in the first handle-constituting sheet portion 33 communicate with each other. and a second communicating portion in which the first filling portion 61 formed in the second sheet portion 32 and the communicating filling portion in the second filling portion 62 formed in the second handle-constituting sheet portion 34 communicate with each other. .
The first communicating portion and the second communicating portion overlap each other in the facing direction of the first main surface portion 20a and the second main surface portion 20b.
In other words, in the container 100 according to the present embodiment, the first communication portion and the second communication portion, which are communication portions between the filling portions extending in mutually different directions, are arranged in the facing direction of the first main surface portion 20a and the second main surface portion 20b. Since the structure overlaps with each other in the first communication portion and the second communication portion, the filling portion with a large cross-sectional area is locally concentrated, and the filling portion on the front side and the back side In this configuration, the force of pushing the side filling portion against each other in the front-rear direction tends to increase locally.
However, as described above, the local joints 29 are formed in the vicinity of the communicating portions of the filling portions extending in mutually different directions. As a result, the cross-sectional area of the filling portion can be locally reduced at the communicating portion, so that the front-side filling portion and the rear-side filling portion press against each other in the front-rear direction. As a result, as described above, a structure in which the handle portion 12 is bent in a desired direction with respect to the body portion 11 can be easily realized.

The present invention is not limited to this example, and the handle portion 12 may be configured by only the first handle-constituting sheet portion 33 (constituted without including the second handle-constituting sheet portion 34).

In the case of this embodiment, a local joint portion 29 is formed in each of the first sheet portion 31 and the second sheet portion 32 (see FIGS. 3, 9 and 10). More specifically, a local joint portion 29 is formed in each of the vicinity of the first communication portion and the vicinity of the second communication portion. Therefore, a good balance of rigidity of the filling portion can be achieved between the first communication portion and the second communication portion (that is, between the front side and the rear side of the container body 20). Therefore, a structure in which the handle portion 12 extends straight laterally (to the right) from the body portion 11 can be realized more easily.

In this embodiment, the local joint portion 29 of the first sheet portion 31 and the local joint portion 29 of the second sheet portion 32 have the same shape. However, the present invention is not limited to this example, and the local joint portion 29 of the first sheet portion 31 and the local joint portion 29 of the second sheet portion 32 may have different shapes.

In the case of this embodiment, the local joint portion 29 of the first sheet portion 31 and the local joint portion 29 of the second sheet portion 32 overlap each other in the front-rear direction. More specifically, substantially the entire local joint portion 29 of the first sheet portion 31 and substantially the entire local joint portion 29 of the second sheet portion 32 overlap in the front-rear direction.

Therefore, when the container 100 is viewed in the facing direction of the first main surface portion 20a and the second main surface portion 20b, the local joint portion 29 of the first sheet portion 31, the local joint portion 29 of the second sheet portion 32, overlap at least partially.
For this reason, it is possible to realize a good balance of rigidity of the filling portion between the first communication portion and the second communication portion, and the structure in which the handle portion 12 extends straight laterally (to the right) from the body portion 11 more easily. can be realized.

Here, as described above, in the case of the present embodiment, both ends of the second filling portion 62 communicate with the first filling portion 61, and the second filling portion 62 and the first filling portion 61 communicate with each other. A local joint portion 29 is formed in the vicinity of the communicating portion on the upper side of the portions, that is, near the spout 15 . That is, the local joint portion 29 is formed at the intersection of the facing portion 67a, the cross-filling portion 69 and the upwardly extending portion 67b, not the intersection of the facing portion 67a, the cross-filling portion 70 and the inclined filling portion 65.

As described above, the container 100 according to the present embodiment includes a discharge portion (spout 15) capable of discharging the content 18 from the containing area 17, and the filling portion 60 is arranged in the body portion 11, as shown in FIG. and a first filling portion 61 including a first portion (opposing portion 67a) and a second filling portion 62 disposed in the handle portion 12 and including a second portion (cross filling portion 69), The second filling portion 62 is formed in a semi-annular shape, and communicating filling portions (intersecting filling portions 69, 70), and a communicating filling portion (intersecting filling portion 69) at a communicating portion corresponding to one of the one end portion and the other end portion of the second filling portion 62 that is disposed near the discharge portion. The local joint portion 29 is formed so that the cross-sectional area of the filling portion 60 perpendicular to the extending direction of the joint portion 29 is locally reduced.
This realizes a structure in which a portion of the handle portion 12 near the discharge portion (spout 15) is bent in a desired direction with respect to the body portion 11 (a structure extending straight laterally (rightward) from the body portion 11). can do. Therefore, when the user grips the handle portion 12 to hold the container 100 and eject the contents 18 from the discharge portion, the body portion 11 can be prevented from wobbling with respect to the handle portion 12, so that the contents 18 can be discharged. becomes easier.

Here, as can be seen from the above description, the body portion 11 has a bottom portion (bottom gusset 13), and the discharge portion (spout 15) is arranged on the opposite side of the bottom portion, that is, on the upper portion of the body portion 11, The handle portion 12 protrudes laterally from the body portion 11, and the one end portion of the second filling portion 62 is arranged above the other end portion of the second filling portion 62. The local joint portion 29 is formed so that the cross-sectional area of the filling portion 60 orthogonal to the extending direction of the communicating filling portion (intersecting filling portion 69) is locally reduced at the communicating portion corresponding to the one end portion of the ing.
Since the body portion 11 has the bottom gusset 13, as shown in FIG. The inclined filling portion 65 formed in 20b is gradually spaced downward from each other.
For this reason, the connecting portion of the facing portion 67a, the cross-filling portion 70 and the inclined filling portion 65 on the first main surface portion 20a and the connecting portion of the facing portion 67a, the cross-filling portion 70 and the inclined filling portion 65 on the second main surface portion 20b. pushes each other back and forth between the facing portion 67a, the cross-filling portion 69 and the upper extending portion 67b on the first main surface portion 20a and the connecting portion of the facing portion 67a, the cross-filling portion 69 and the upper extending portion 67b on the first main surface portion 20a and the facing portion 67a on the second main surface portion 20b It tends to be weaker than the force of pushing forward and backward between the communicating portion of the extension portion 67b.
Further, since the local joint portion 29 is formed in the vicinity of the communication portion on the upper side (the intersection of the facing portion 67a, the cross filling portion 69, and the upwardly extending portion 67b), the container 100 is held by gripping the handle portion 12. Then, when discharging the contents 18 from the spout 15, the spout 15 can be easily operated in the intended direction.
For this reason, from the viewpoint of sufficiently ensuring the structural strength of the boundary portion between the body portion 11 and the handle portion 12, the upper communication portion (the intersection portion of the facing portion 67a, the cross filling portion 69, and the upward extending portion 67b) and the When the local joint 29 is formed only at one of the lower communication points (the intersections of the opposing portion 67a, the cross-filling portion 70, and the inclined filling portion 65), the local joints are formed only near the upper communication portion. It can be said that forming 29 is reasonable. In particular, when the container 100 has a large capacity, the holding of the container 100 is improved by forming the local joints 29 only at the upper communicating portion and not forming the local joints 29 at the lower communicating portion. is superior.
However, the present invention is not limited to this example, and the local joints 29 may be formed at both the upper crossing portion and the lower crossing portion, for example, when the container is not a large-capacity size container.

[Second embodiment]
Next, a second embodiment will be described with reference to FIGS. 11 and 12. FIG.
The container 100 according to the present embodiment differs from the container 100 according to the first embodiment in the points described below, and is otherwise the same as the container 100 according to the second embodiment. It is configured.

In the case of the present embodiment, as shown in FIGS. 11 and 12, when the container 100 is viewed in the opposing direction (front-rear direction) between the first main surface portion 20a and the second main surface portion 20b, the first sheet portion 31 is The local joint portion 29 and the local joint portion 29 of the second sheet portion 32 are arranged at positions shifted from each other. As a result, as shown in FIG. 12, the size balance between the communication portion 111 and the communication portion 112 on the front side (first sheet portion 31) and communication with the communication portion 111 on the back side (second sheet portion 32) are achieved. The size balance with the portion 112 can be different from each other. For this reason, although depending on conditions such as the shape of the filling portion 60, the force between the communicating portions 111 and 112 on the front side and the communicating portions 111 and 112 on the back side push each other more than in the first embodiment. can be expected to be reduced. Therefore, it can be expected that the stability of the orientation of the handle portion 12 with respect to the body portion 11 is improved.

Also in this embodiment, both of the local joints 29 are arranged along the boundary line BL (FIG. 11). Therefore, in this embodiment as well, a structure in which the handle portion 12 is bent in a desired direction with respect to the body portion 11 can be realized, and the first portion (facing portion 67a) and the third portion (upwardly extending portion) of the container body 20 can be formed. It is possible to sufficiently secure the mechanical strength of the portion where the projecting portion 67b) is formed.

In the case of this embodiment as well, it is possible to provide the container 100 having a structure that is easy to hold by the user, and to easily realize a structure in which the handle portion 12 is bent in a desired direction with respect to the body portion 11. can be done.

In this embodiment, when the container 100 is viewed in the front-rear direction, the outline of the local joint 29 of the first sheet portion 31 and the outline of the local joint 29 of the second sheet 32 overlap each other. . That is, when the container 100 is viewed in the direction in which the first main surface portion 20a and the second main surface portion 20b face each other, although it is faint, the local joint portion 29 of the first sheet portion 31 and the local portion of the second sheet portion 32 At least a part of the joint portion 29 overlaps.
Therefore, in the case of the present embodiment as well, it is possible to realize a good balance of rigidity of the filling portion between the first communicating portion and the second communicating portion, and the handle portion 12 can be more easily moved straight sideways ( to the right) can be realized.

[Third embodiment]
Next, a third embodiment will be described with reference to FIGS. 13 and 14. FIG.
The container 100 according to the present embodiment differs from the container 100 according to each of the above embodiments in the points described below, and in other respects, is configured in the same manner as the container 100 according to each of the above embodiments. ing.

In each of the embodiments described above, an example in which the local joint portion 29 is formed in an island shape in the non-joint portion 24 has been described. On the other hand, in the present embodiment, as shown in FIGS. 13 and 14, the local joint portion 29 is a joint portion between the outer film 22 and the inner film 23 of the main body constituting sheet material 21, and the non-joint portion 24 is formed. It is formed continuously with the surrounding part.
More specifically, the local joint portion 29 is a joint portion between the outer film 22 and the inner film 23 of the main body constituting sheet material 21 and extends from the portion surrounding the non-joint portion 24 toward the inside of the non-joint portion 24. It is formed in a projecting shape. In other words, the local joint 29 is shaped like a peninsula.

In the example of FIGS. 13 and 14, the local joint portion 29 of the first sheet portion 31 and the local joint portion 29 of the second sheet portion 32 extend in opposite directions and are arranged so as not to overlap each other in the front-rear direction. It's becoming
However, also in this embodiment, the local joint portion 29 of the first sheet portion 31 and the local joint portion 29 of the second sheet portion 32 may overlap each other in the front-rear direction. When these local joints 29 overlap each other in the front-rear direction, the entire local joints 29 may overlap (as in the first embodiment), or the local joints 29 may overlap (as in the second embodiment). may overlap.

Also in this embodiment, both of the local joints 29 are arranged along the boundary line BL (FIG. 13). Therefore, in the present embodiment as well, the cross-sectional area of the filling portion 60 at the first communication portion and the second communication portion can be locally reduced. A bent structure can be realized, and the mechanical strength of the portion of the container body 20 where the first portion (facing portion 67a) and the third portion (upwardly extending portion 67b) are formed can be sufficiently ensured. .

In the case of this embodiment as well, it is possible to provide the container 100 having a structure that is easy to hold by the user, and to easily realize a structure in which the handle portion 12 is bent in a desired direction with respect to the body portion 11. can be done.

The present invention is not limited to the above-described embodiments and modifications, and includes various modifications and improvements as long as the object of the invention is achieved.

For example, although an example in which the third portion is formed on the body portion 11 has been described above, the third portion may be formed on the handle portion 12 .

Further, the container 100 does not have to be formed with the penetrating portion 19 . That is, the portion of the handle portion 12 surrounded by the second filling portion 62 may be closed by a membrane formed of the main body forming sheet material 21 or the inner bag forming sheet material 41, for example.

For example, the communication region 49 may not be formed in the handle portion 12 . That is, the accommodation area 17 may be a closed area within the body portion 11 . Also, the inner container (for example, the inner bag 40) may not be arranged inside the handle portion 12 (the inner container may be arranged only inside the body portion 11).

Further, the outer film 22 and the inner film 23 of the main body-constituting sheet material 21 may be formed in the same shape, and may be superimposed so that their outlines match each other.
Furthermore, the main body-constituting sheet material 21 and the inner bag-constituting sheet material 41 may be formed in the same shape, and may be superimposed so that their outlines match each other.
Moreover, in the above description, an example in which the container 100 includes the inner bag 40 (inner container) has been described, but the container 100 may be configured without the inner bag 40 .
In the above-described embodiment, the local joint portion 29 is arranged along the boundary line BL. may be located at a distance from the
