In addition, the dimensional ratios in the drawings are changed for convenience of explanation and may be different from the actual ratios.

《Conventional bag with flexible handle》
One form of the conventional bag with a flexible handle is shown in FIG. In FIG. 16, the bag 1 with a flexible handle is the bag part 2, the 1st handle part 3 attached to the bag part 2, and the spout part 4 (FIG. 16 has shown the state with which the cap was mounted | worn. The first handle portion 3 includes the first handle portion 5 and the first suspension portion 6 that connects the first handle portion 5 and the bag portion 2. The first suspension part 6 includes two or more first columnar suspension parts 6a; the first handle part 5 extends from the first handle part 5 toward the bag part 2, and the first handle part 6a. A first fold portion 7 formed so as to be folded so as to overlap the first handle portion 5 when the handle portion 5 is gripped; A gripping opening 8 surrounded by four sides by one handle 5 and two or more first columnar suspensions 6 a is provided; the spout 4 is formed in the gripping opening 8. In FIG. 16, the first folding part 7 is separated from the first columnar suspension part 6a by a notch 9 between the first folding part 7 and the first columnar suspension part 6a.

  The flexible handle-equipped bag 1 stores a liquid, powder, or the like having a predetermined weight, holds the first handle 5 while folding the first fold 7, and the flexible handle. When the bag 1 is lifted, the load concentrates on the end of the notch 9 on the first handle 5 side. That is, a downward force (force due to gravity applied to the mass of the bag portion) acts on the first columnar suspension portion 6a, and the first handle portion 5 and the first folding portion 7 have an upward direction. Force (the force that lifts the bag, that is, the force acting on the opposite side of the direction of gravity applied to the mass of the bag portion) acts, and this causes the end of the notch 9 on the first handle portion 5 side. The tension is concentrated. From this, the present inventors have found that the first handle 5 is torn from the end of the notch 9, and as a result, the first handle 3, particularly the first handle 5 may be damaged. It was.

<< Bag with Flexible Handle of the Present Invention >>
The flexible handle-equipped bag of the present invention includes a bag part, a first handle part attached to the bag part, and a spout part; the first handle part includes a first handle part and a first handle part. A first suspension part connecting the handle part and the bag part; the first suspension part is two or more first columnar suspension parts, or two or more first columnar suspension parts and two or more A first planar suspension connected to the first column suspension; the first handle extends from the first handle toward the bag and grips the first handle A first folded portion formed to be folded so as to overlap with the first handle portion; a corner portion between the first handle portion and the two or more first columnar suspension portions The bag is curved; the bag shows at least one of the following (a) to (e):
(A) The length D between one first columnar suspension part and the other one first columnar suspension part is 85 mm or more, and the curved curve processing r is 13.0 mm or more. ,
(B) The length D between one first columnar suspension part and the other one first columnar suspension part is 90 mm or more, and the curved curve processing r is 10.0 mm or more. ,
(C) The length D between one first columnar suspension part and the other one first columnar suspension part is 110 mm or more, and the curved curve processing r is 5.0 mm or more. ,
(D) The length D between one first columnar suspended portion and the other one first columnar suspended portion is 130 mm or more, and the curved curve processing r is 2.0 mm or more. ,
(E) The relationship between the length D (mm) between one first columnar suspension and the other one first columnar suspension and the curved curve r (mm) is as follows: Represented by the formula (I):
r ≧ −0.2375D + 33.000 (I)
[Where D ≧ 85 mm].

  In the bag with a flexible handle of the present invention, the shape of the corner between the first handle portion and the two or more first columnar suspension portions is curved, so when the bag is lifted with the handle portion In addition, the upward force applied to the first handle portion and the downward force applied to the first columnar suspension portion can be dispersed by the curve.

  Moreover, it is preferable that the curved curve r at the corner is large. In this case, it is not bound by any logic, but since the curve is a gentle shape, the upward force applied to the first handle and the downward force applied to the first column suspension And can be more efficiently distributed along the curve. Therefore, the value of the curve processing r is not particularly limited, but is 2.0 mm or more, 3.0 mm or more, 5.0 mm or more, 8.0 mm or more, 10.0 mm or more, 13.0 mm or more, or 15.0 mm or more. It's okay. Note that the upper limit of the value of r is not particularly limited. This is because the larger the value of r, the more the shape of the curve becomes substantially linear, and there is a structural limitation of the first handle part that forms the corner on the curve. This is because a person skilled in the art can adjust appropriately.

  Moreover, in the bag with a flexible handle of this invention, the length between one 1st columnar suspension part and another 1st columnar suspension part may be comparatively long. Here, since the width of the back of the hand of an adult male is about 8.3 cm on average, when the center of the first handle is gripped, the length between the first columnar suspensions is relatively By being long, for example, 85 mm or more, a gap is formed between the hand and the first columnar suspension. Therefore, although not bound by any logic, according to the bag with a flexible handle of the present invention, the position of the force application point in the direction from the first handle to the bag, The distance between the application point positions of the forces in the direction to the handle of the handle is relatively long, thereby concentrating these forces on the corners between the first handle and the first column suspension It is thought that it can be dispersed.

  The length D between one first columnar suspension and the other first columnar suspension may be 85 mm or more, 90 mm or more, 100 mm or more, 110 mm or more, 120 mm or more, or 130 mm or more. The upper limit of the length is not particularly limited. This is because the longer the length, the longer the length of the first handle, and considering the subject that handles this flexible handle bag, those skilled in the art who are in contact with the present invention This is because it can be adjusted appropriately.

Further, as described above, there is a correlation between the curved curve processing r at the corner and the length D between one first columnar suspension and the other first columnar suspension. A relationship may exist. Specifically, in order to suppress breakage of the handle portion of the bag with a flexible handle, when the length D is long, the curve processing r may be relatively small and when the length D is short. The curve processing r may be relatively large. For example, a relationship represented by the following formula (I) may exist between the length D and the curve processing r:
r ≧ −0.2375D + 33.000 (I)
[Where D ≧ 85 mm].

  The value of the r-intercept is not particularly limited, but may be 33.000, 35.000, 38.000, or 40.000.

Therefore, the length D between one first columnar suspended portion and the other one first columnar suspended portion and the curved curve processing r of the corner portion satisfy the above values, respectively. For example, it is preferable to satisfy at least one of the following (a) to (e):
(A) The length D is 85 mm or more and the curve processing r is 13.0 mm or more.
(B) The length D is 90 mm or more and the curve processing r is 10.0 mm or more.
(C) The length D is 110 mm or more and the curve processing r is 5.0 mm or more,
(D) The length D is 130 mm or more and the curve processing r is 2.0 mm or more.
(E) The relationship between the length D (mm) and the curved curve processing r (mm) is represented by the following formula (I):
r ≧ −0.2375D + 33.000 (I)
[Where D ≧ 85 mm].

  As a result, it is possible to provide a flexible handle-attached bag having improved durability against a load applied to the first handle portion and the first columnar suspension portion connected to the first handle portion.

FIG. 1 is a schematic front view showing a first embodiment of a bag with a flexible handle of the present invention. In FIG. 1, a bag 100 with a flexible handle includes a bag part 102, a first handle part 103 attached to the bag part 102, and a spout part 104 (FIG. 1 shows a state where a cap is attached. The first handle portion 103 has a first handle portion 105 and a first suspension portion 106 connecting the first handle portion 105 and the bag portion 102. The first suspension part 106 includes two or more first columnar suspension parts 106a and a first planar suspension part 106b connected thereto; the first handle part 105 is a first handle part. There is a first folding portion 107 that extends from the portion 105 toward the bag portion 102 and that is folded so as to overlap the first handle portion 105 when the first handle portion 105 is gripped. doing. Further, the shape of the corner 101 between the first handle 105 and the two or more first columnar suspensions 106a is curved; one first columnar suspension 106a and one other first columnar suspension 106a. The relationship between the length D (mm) between the columnar suspended portions 106a and the curved curve processing r (mm) is expressed by the following formula (I):
r ≧ −0.2375D + 33.000 (I)
[Where D ≧ 85 mm].

  Note that the term “two or more column suspensions” includes two or more column suspensions on both sides of the folding portion and other column suspensions that overlap these column suspensions, if any. It is. For example, in a gusset bag or the like, two columnar suspension parts connected via a handle part are respectively provided on the handle part on the front side and the back side of the bag, and a total of four columnar suspension parts may exist. . Further, for example, in a flat bag or the like, two columnar suspension portions connected to each other via a handle portion may be provided in the handle portion of the bag, and there may be two columnar suspension portions in total.

  In particular, the corner portion 101 is cut into a hook shape, and the hook portion of the hook shape forms an arcuate curve. Note that the hook tip of the hook-shaped hook part and the end of the hook-shaped handle part face the bag part 102, and the apex of the arc of the hook-shaped hook part faces the first handle part 105. ing. In addition, there are a total of two scissors-shaped cuts on both sides of the first folding part 107, and these scissors are arranged so that their scissors portions face each other. Further, in the two scissors-shaped cuts, there are two ends opposite to the scissors portion, that is, two scissors-shaped handle portions, and an intermediate portion between these ends is linearly cut, As a result, the ends are connected. In this way, the contour of the first folding part 107 is configured.

The configuration of the bag with a flexible handle in FIG. 2 is the same as the configuration of the bag with a flexible handle in FIG. 1 except that the corner-shaped cuts at the corners are different from those in FIG. Therefore, the description of the configuration other than the notch-shaped cut at the corner is omitted.

  Specifically, the corner 201 of the bag with the flexible handle in FIG. 2 is substantially the same as the bowl-shaped cut in the corner 101 in FIG. These differences are the ridge portions of the ridge-shaped cut. That is, the ridge portion of the corner portion 201 has a rounded half-square shape.

  Further, in the configuration of the bag with a flexible handle in FIG. 3, the opening of the bag is formed by extending the cut-out of the ridge shape at the corners and cutting out a part of the first handle portion. 1 is the same as the configuration of the bag with a flexible handle in FIG. Therefore, the description of the configuration other than the notch-shaped cut at the corner is omitted.

  Specifically, the shape of the corner portion 301 of the flexible handle bag shown in FIG. 3 is substantially the same as the shape of the collar portion of the corner portion 101 shown in FIG. However, the corner portion 301 is not a saddle-shaped cut, but this portion is punched out. Specifically, an intermediate portion between two heel-shaped tips is cut linearly, thereby connecting the tips; at the ends of the two heel-shaped handle portions, The middle part of the two parts is cut in a straight line, thereby connecting the ends to each other; as a result, the opening of the shape punched by the two scissors-shaped cuts and the straight cuts of the two middle parts Is formed on the first handle portion of the flexible handle-equipped bag of FIG.

  Moreover, in the bag with a flexible handle of this invention, the 2nd handle part may be attached to the bag part.

  Therefore, for example, it is possible to use such as gripping these handle portions with both hands and easily taking out the contents from the bag portion.

r ≧ −0.2375D + 33.000 (I)
[Where D ≧ 85 mm].

  Therefore, it is possible to provide a flexible handle-attached bag in which durability against a load applied to the second handle portion and the second suspension portion connected thereto is further improved.

  FIG. 4 is a schematic front view showing a second embodiment of the flexible handle-equipped bag of the present invention. The configuration of the flexible handle-equipped bag 400 of FIG. 4 is the same as that of the flexible handle-attached bag of FIG. 1 except that the second handle portion is formed on the flexible handle-attached bag 100 of FIG. Is the same. Therefore, description of structures other than the said 2nd handle part is abbreviate | omitted.

  The second handle portion 413 of the flexible handle-equipped bag 400 of FIG. 4 is formed on the opposite side of the bag portion 402 from the first handle portion 403. The second handle portion 413 of the bag with flexible handle 400 of FIG. 4 has a second handle portion 415 and a second suspension portion 416 that connects the second handle portion 415 and the bag portion 402. The second suspension part 416 includes two or more second columnar suspension parts 416a and a second planar suspension part 416b connected to the two or more second columnar suspension parts 416a. The second handle 415 extends from the second handle 415 toward the bag 402 and is folded so as to overlap the second handle 415 when the second handle 415 is gripped. The second folding part 417 is formed as described above, and on the lateral side of the second folding part 417, the corner between the second handle part 415 and the two or more second columnar suspension parts 416a. The shape of the part 411 is curved.

  In particular, the corner 411 is cut in an arc shape, and this arc-shaped arc portion forms a curve. Note that the two ends of the arc portion face the bag portion 402, and at the apex of the arc portion, that is, at the two ends of the arc portion, the protrusion of the middle point of the line from one end to the other end The direction is toward the second handle 415.

In particular, in the first handle portion 503 of the flexible handle-equipped bag 500, the length between one first columnar suspension portion 506a and the other one first columnar suspension portion 506a is relatively long. The movable range of the spout portion 504 is relatively wide.

  FIG. 6 is a schematic view showing a state in which the contents are taken out from the flexible handle-equipped bag of FIG. In this flexible handle-equipped bag 600, since the length between the spout portion and the first columnar suspension portion is relatively long, it is possible to adjust the movement of the spout portion with an appropriate margin.

  FIGS. 7-9 is a schematic front view which shows another form of the bag with a flexible handle of FIG. The configuration of the bag 700 with the flexible handle in FIG. 7 is the same as the configuration of the bag with the flexible handle in FIG. 5 except that the shape of the second handle portion is different from that in FIG. is there. 8 and 9 is the same as that shown in FIG. 5, except that the shape of the first handle portion is different from that shown in FIG. Is the same. Therefore, regarding the description of the configuration of the flexible handle-attached bag of FIGS. 7 to 9, the description of the components of FIGS. 7 to 9 that are the same as the components of FIG. 5 is omitted.

  Since the shape of the second handle portion 713 in FIG. 7 is substantially the same as the shape of the first handle portion 301 in FIG. 3, this description is omitted. Moreover, since the shape of the 1st handle part of FIG.8 and 9 and especially the corner | angular parts 801 and 901 of the both sides of a 1st folding part are respectively substantially equivalent to the thing of FIG.1 and 2, respectively, these description is carried out. Omitted. The difference between the corners in FIGS. 9 and 2 is whether the corner is not punched or punched.

  FIG. 10 is a schematic view showing a state in which contents are put in the flexible handle-equipped bag of FIG. In FIG. 10, the spout 504 (FIG. 5 shows a state in which no cap is attached) is formed in the grip opening 508, and two first columnar suspensions are formed on the front and back surfaces of the bag 502. 506a is provided, and there are a total of four first column suspensions 506a.

  In addition, the second handle part is formed also in the conventional bag with a flexible handle. For example, in FIG. 16, the flexible handle-equipped bag 1 has a second handle portion 13. Therefore, it is possible to perform an operation of grasping the first handle portion 3 and the second handle portion 13 and taking out the contents stored in the bag portion. However, in the first handle portion 3 of this conventional bag 1 with flexible handle, the length between one first columnar suspension portion 6a and the other one first columnar suspension portion 6a is short. The range of motion of the spout is relatively narrow. Therefore, when the content contained in the bag portion is taken out from the spout portion, it may be difficult to accurately control the arrival position of the content. In addition, since the length between the spout portion and the first columnar suspension portion is relatively short, it may be relatively difficult to adjust the movement of the spout portion.

  FIG. 17 is a schematic view showing a state in which the contents are taken out from the flexible handle-equipped bag of FIG. In this conventional bag with a flexible handle, since the length between the spout portion and the first columnar suspension portion is relatively short, it may be relatively difficult to adjust the movement of the spout portion. is there.

  Moreover, in the bag with a flexible handle of the present invention, in one aspect, at least a part of the first fold line between the first fold portion and the first handle portion may not be sealed; Both sides of the first fold line may be at least partially sealed; and the first fold line is folded when the first fold line is gripped by the first handle. It may be a convenient line between one folding part.

  Since there is an unsealed portion in the first fold line between the first fold and the first handle, the first fold can be easily folded. Further, since both sides of the first planned folding line are at least partially sealed, the folding position is clear and it is difficult to bend in the direction perpendicular to the planned folding line. Furthermore, when the flexible handle-attached bag is formed by stacking a plurality of films or the like, since both sides of the first fold line are at least partially sealed, The film does not have to be individually deformed at the first handle or the first folding part.

  Therefore, the ratio of the sealed length of the first fold line may be 50% or less, 45% or less, 40% or less, or 30% or less.

  Moreover, regarding the ratio of the sealed length of the second fold line, the description of the ratio of the sealed length of the first fold line can be referred to.

  FIG. 11: is a schematic front view which shows 4th embodiment of the bag with a flexible handle of this invention. The configuration of the flexible handle-equipped bag 1100 in FIG. 11 is the same as the configuration of the flexible handle-equipped bag 100 in FIG. 1 except that a seal 1110 is provided, as compared to the configuration in FIG. . Therefore, description of components other than the seal 1110 is omitted.

  The seal 1110 of the flexible handle-equipped bag 1100 in FIG. 11 includes four substantially linear seals 1110a, b, and c, which are arranged in this order. Specifically, the seals 1110 a and b are present on the first folding part 1107, and the seal 1110 c is present on the first handle part 1105. The longitudinal direction of these seals is the same as the direction from one first columnar suspension 1106a to the other first columnar suspension 1106a. In addition, the first planned folding line 1111 exists between the seals 1110b and 1110c, so that the first folding planned line 1111 extends along the first planned folding line 1111 and overlaps the first handle 1105. One folding part 1107 is folded.

  The first planned bending line 1111 is a convenient line that may be bent, and the bending is not necessarily strictly performed along this line. However, it should be understood that the folding position can be substantially determined by the boundary between the first fold and the first handle, that is, the position of the corner of the first handle and the position of the seal. That is, those skilled in the art who are in contact with the present invention can accurately determine the position of the seal so that the present invention can be implemented.

  12 is a schematic front view showing another embodiment of the flexible handle-equipped bag of FIG. 11. The configuration of the bag with flexible handle 1200 of FIG. 12 is the same as that of the bag with flexible handle 1100 of FIG. 11 except that the shape of the seal is different from that of FIG. Therefore, the description of the configuration other than the seal, that is, the seal 1210 is omitted.

  The seal 1210 of the flexible handle-equipped bag 1200 of FIG. 12 is composed of four substantially linear seals 1210a, b, and c. The seal 1210a is present on the first folding part 1207, and the seal 1210c is present on the first handle 1205. The longitudinal directions of these seals 1210a and c are the same as the direction from one first columnar suspension portion 1206a to the other first columnar suspension portion 1206a. Further, two seals 1210b exist on both sides of the seal 1210a, that is, sandwiching the seal 1210a, are formed so as to be orthogonal to the first fold line 1211, and the first folding portion 1207 and the first handle are formed. It is formed on the portion 1205. The longitudinal direction of these two seals 1210b is the same as the direction from the first folding part 1207 to the first handle part 1205.

  In FIG. 12, the seal 1210 b is formed on the first planned bending line 1211. However, the region of the first planned bending line 1211 to which the seal 1210b is applied is a part, and the first bending planned line 1211 does not have to be difficult to bend.

  FIG. 13 is a diagram showing an example of a seal applied to the flexible handle-equipped bag of FIG. The other structure of the bag 1300 with a flexible handle in FIG. 13 is the same as the structure of the bag with a flexible handle in FIG.

  The components of the flexible handle-equipped bag of the present invention will be described below.

<Bag part>
Although a bag part is not specifically limited, A bag part is a part which accommodates a stored item, for example, a liquid and / or powder. The formation of the bag portion is not particularly limited. For example, a plurality of films are overlapped, and the periphery of the portion forming the bag portion is excluded except for the spout portion, or a plurality of films are overlapped to overlap the bag portion. This can be done by sealing the periphery of the part to be formed.

<Toride part>
A handle part is a part which lifts a bag part by grasping this, or a part which carries a bag part. The shape of the handle part is not particularly limited when the handle part has a handle part and a suspension part connecting the handle part and the bag part. The dimensions of the handle are not particularly limited as long as the flexible handle-equipped bag of the present invention can be implemented.

(Pattern)
The handle portion may be a gripping portion, and has a folding portion that extends from the handle portion toward the bag portion and is folded so as to be overlapped with the handle portion when the handle portion is gripped. .

(Suspension part)
The suspension part is a part that connects the handle part and the bag part, two or more column-like suspension parts existing on both sides of the folding part, and an optional planar shape connected to the column-like suspension part. Has a suspension. The width of the column suspension is not particularly limited as long as it has durability and handleability to carry the bag. You may determine the width | variety of a column-shaped suspension part by considering the object which handles this flexible handle bag, the contents put into the said bag, its volume, and mass, for example.

<Outlet section>
The spout portion is a portion used to take out and / or put an object such as a liquid or powder from the bag portion. As long as the bag with a flexible handle according to the present invention can be implemented, a channel, such as a pipe, may be formed between the spout part and the bag part. Examples of the form of the spout part include a spout form and a form in which a seal dedicated to the spout is applied to a part of the bag part. Among these, in the form in which a seal dedicated to the spout is applied to a part of the bag portion, a notch for opening may be made beside the seal.

<Others>
In addition to the above-described spout portion, another spout portion may be attached to the bag portion. In this case, one spout part may be used to put an object, for example, liquid or powder, and the other spout part may be used to take out the object. For example, regarding a spout part in a form in which a seal dedicated to the spout is provided on a part of the bag part, this may be used to take out the object.

  Moreover, the structure of the bag with a flexible handle of this invention will not be specifically limited if it is the structure which can provide flexibility to the said bag. The bag with a flexible handle of the present invention may be formed of a resin film, for example, a thermoplastic resin film. Examples of the film include linear low density polyethylene (LLDPE), ionomer film (IO film), polyethylene. Film (PE film), polyvinyl chloride film (PVC film), polyvinylidene chloride film (PVDC film), polyvinyl alcohol film (PVA film), polypropylene film (PP film), polyester film, polycarbonate film (PC film), polystyrene Film (PS film), Polyacrylonitrile film (PAN film), Ethylene vinyl acetate copolymer film (EVA film), Linear low density polyethylene film (LL film) Ethylene - vinyl alcohol copolymer film (EVOH film), an ethylene - methacrylic acid copolymer film (EMAA film), nylon film (NY film), and the like can be cited polyamide (PA) film. Although it does not specifically limit as an example of a structure of the bag with a flexible handle of this invention, PET / AL / PET / L-LDPE, OPP / PE, OPP / EVA, NY / L-LDPE, and OPP / L- LDPE etc. can be mentioned. The thickness of the film is not particularly limited, but may be 10 μm, 15 μm, 20 μm, 50 μm, 100 μm, or 130 μm, and / or 500 μm, 300 μm, or 150 μm. .

  In consideration of characteristics such as durability, sealability, portability, transportability, stretchability, corrosivity, heat retention, etc., a material constituting the flexible handle-equipped bag of the present invention, for example, a film , Adhesives, and / or materials such as foils may be determined.

  The present invention will be described in more detail with reference to the following examples, but it goes without saying that the scope of the present invention is not limited by these examples.

<< Examples 1 to 21 >>
A bag with a flexible handle of 600 mm × 250 mm including a bag part and a handle part attached to the bag part was prepared. For the production of the bag, four films having a laminated structure of NY (15 μ) / LLDPE (20 μ) / LLDPE (130 μ) are prepared, and these films are directed to the innermost surface, that is, the inner side, And it performed by giving a heat seal. The handle part of the created bag with a flexible handle includes a handle part and a suspension part that connects the handle part and the bag part, and the suspension part includes four column-like suspension parts. Further, the handle portion has a folding portion formed so as to extend from the handle portion toward the bag portion and to be folded so as to overlap the handle portion when the handle portion is gripped. Furthermore, the shape of the corner portion between the handle portion and the four columnar suspension portions is a curved shape, and the corner portion is specifically subjected to curve processing (r). In addition, the number of columnar suspension parts is the total number of the two columnar suspension parts on the front surface of the bag part and the two columnar suspension parts on the back surface of the bag part.

  FIG. 14 is a schematic diagram showing a part of the handle part of the bag with the flexible handle of the example. In FIG. 14, the curve processing r of the corner portion and the length D between one columnar suspension portion and the other one columnar suspension portion in the two columnar suspension portions on both sides of the folding portion are shown.

<Evaluation>
About the bag with a flexible handle of Examples 1-21, durability with respect to the load concerning a handle | pattern part and the columnar suspension part connected with this was evaluated. Specifically, 10 L of water was filled in the bag portion of the bag with a flexible handle, the handle portion of the bag was gripped, and the bag was vibrated up and down. The up-and-down movement was made to vibrate once, and the bag was vibrated 10 times. Curved corner r, length D between one column suspension and the other column suspension in the two column suspensions on both sides of the fold, and breakage of the handle and / or column suspension The presence or absence of is shown in Tables 1 to 4 below.

  Table 4 summarizes Tables 1 to 3.

  From Table 1, it can be seen that when the length D is 90 mm, only the bag with the flexible handle of Example 1 is not damaged. This is not bound by any logic, but because the r of the corner curve processing (r) of Example 1 is larger than that of Examples 2 to 7, the upward force applied to the handle and the columnar shape This is probably because the downward force applied to the suspension part was efficiently dispersed along the curve.

  From Table 2, when length D is 110 mm, it turns out that the handle part of the bag with a flexible handle of Examples 8-10 is not damaged. Further, the length D of Example 8 is longer than that of Example 1, while the curve processing r at the corners of Example 8 is equivalent to that of Example 1. Therefore, it is considered that breakage of the handle portion of the flexible handle-equipped bag of Example 8 could be avoided in the same manner as the logic of Example 1 above.

  Further, the length D of the flexible handle bag of Examples 9 and 10 is longer than that of Examples 2 and 3, respectively, while the curve processing r of Examples 9 and 10 is equivalent to that of Examples 2 and 3, respectively. . Also, the flexible handle-equipped bags of Examples 2 and 3 are damaged, while those of Examples 9 and 10 are not damaged. This is not bound by any logic, but because the length D of Examples 9 and 10 is relatively long, the point of action of the upward force on the handle and the downward force on the column suspension This is probably because the distance from the position of the force application point is increased, and as a result, these forces are not concentrated on the corner between the handle and the column suspension.

  From Table 3, when length D is 130 mm, it turns out that the handle part of the bag with a flexible handle of Examples 15-19 is not damaged. That is, the length D of Examples 15-19 is longer than that of Examples 1 and 8-10, so that the handle and the column-like suspension connected to it even when the curving r is relatively small. It is understood that the durability against the load applied to the surface is improved.

  Lengths D (mm) and curve processing for Examples 1, 10, and 19, which are examples of boundaries where breakage of the handle part can be suppressed, and Examples 2, 11, and 20, which are examples of boundaries where damage of the handle part occurs The relationship between r (mm) is shown in FIG. FIG. 15 shows that the length D correlates with the curve processing r. Specifically, in order to suppress breakage of the handle portion of the bag with a flexible handle, when the length D is long, the curve processing r may be relatively small and when the length D is short. It is understood that the curve processing r should be relatively large.

Moreover, the approximate straight lines of Examples 1, 10 and 19 in FIG. 15 clarify the above correlation, and are represented by the following formula (II).
r = −0.2375D + 33.958 (II)

In addition, between the curve processing r in Examples 1, 10, and 19, which are boundary examples that can suppress the breakage of the handle part, and Examples 2, 11, and 20 that are boundary examples in which the handle part is damaged There is a difference of at least 1.5 mm. Therefore, the length D which can suppress the damage of a handle part, and the curve process r may exist during this time. Accordingly, at least when the curve processing r exists in the range of the following value represented by the following formula (I), the durability against the load applied to the handle portion and the columnar suspension portion connected to the handle portion. It is thought that the nature improves more.
r ≧ −0.2375D + 33.000 (I)

  It should be understood that the above formula (I) is also a relational expression of the length D.
