For example, Japanese Patent Application Laid-Open No. 2005-8248 (Patent Document 1) discloses a package containing a plurality of roll products such as toilet paper as a package to be packaged. In this package, a handle portion is provided on the upper end side of the main body portion in which the roll product is housed, and the handle portion is further provided with two finger hook holes.

Japanese Unexamined Patent Publication No. 2005-8248

However, in the conventional packaging bag disclosed in Patent Document 1, the shape of the finger hook hole changes during carrying depending on the weight of the packaged object, the holding method of the packaging bag containing the packaged object, and the like, and the handle The finger may be strained, for example, the finger may be tightened to the part and the finger may hurt. In addition, since the film that is the material of the packaging bag is managed in a rolled state, it is often compressed and hardened, and it is inserted into the finger hole of the handle part formed of such hardened film. When the finger is hung, if the finger is tightened, the burden on the finger becomes even greater. As described above, in the conventional packaging bag, the fingers are tightened when carrying the bag, which puts a heavy burden on the fingers.

An object of the present invention is to provide a packaging bag capable of suppressing finger tightening and reducing the burden on the fingers.

In order to solve the above problems, the first aspect of the present invention includes a main body portion for accommodating the object to be packaged, a handle portion provided at the upper end of the main body portion, and a finger hook portion provided on the handle portion. It has a pair of slits formed above the finger hook portion, and the pair of slits is inclined from the finger hook portion toward the upper end of the handle portion, and the distance between the pair of slits is the handle portion. A packaging bag that extends in the longitudinal direction.

The main body constitutes the main body of the packaging bag in which the object to be packaged is housed. The main body can be formed of a film such as resin. The packaged body housed in the main body is not particularly limited, and examples thereof include toilet paper, kitchen paper, baby or nursing paper diapers, and menstrual napkins. The form of the packaged body is not particularly limited, and may be a roll shape, a laminated shape, or the like. Further, when the articles constituting the packaged body are accommodated in the main body portion, the number of articles to be accommodated is not limited to one, and may be a plurality.

The handle portion is provided at the upper end of the main body portion and constitutes a part of the package. The handle portion may be made of a film such as resin, and the material of the film may be the same as that of the main body portion. The handle portion is provided with a finger hook portion.

The finger hook portion is a portion on which the purchaser of the article (hereinafter referred to as a user) hangs his / her finger when holding the handle portion. The finger hook portion can be formed by a hole penetrating the handle portion. The finger hook portion provided on the handle portion may be formed of a plurality of holes. Further, the hole penetrating the handle portion may be provided in the handle portion from the beginning, or a notch such as a perforation may be made so that the user can break the notch or the like and open the hole by himself / herself when purchasing the article. You may do it.

The pair of slits is formed above the finger hook. The pair of slits has a configuration that is inclined from the finger hook portion toward the upper end of the handle portion and extends so that the distance between the pair of slits is widened in the longitudinal direction of the handle portion.

In the first aspect, since such a pair of slits is formed above the finger hook portion, the user's finger is tightened while the user puts his / her finger on the finger hook portion of the handle portion. When a force is applied to the finger hook, a part of the handle is torn from the finger hook to the pair of slits, and the finger hook is expanded so as to spread in the longitudinal direction of the handle. Therefore, when the packaging bag containing the packaged body is carried, tightening to the user's finger is suppressed.

Further, after a part of the handle portion is torn, the part of the torn handle portion can serve as a cushioning material between the finger and the finger hook portion. Therefore, when carrying the packaging bag containing the packaged object, the tightening force applied to the user's finger can be reduced.

As described above, according to the first aspect, when the user hangs his / her finger on the finger hook portion of the handle portion and carries the packaging bag containing the object to be packaged, the burden on the user's finger is reduced. Can be done.

In the second aspect, each slit is composed of a notch having a predetermined length or a plurality of notches having a length shorter than the predetermined length. By forming the slit with a notch having a predetermined length, when a tightening force is applied to the user's finger and a part of the finger hook is torn, the handle is torn from the finger hook toward the pair of slits. Since it is easy, the handle portion is easily expanded so as to spread in the longitudinal direction. In addition, by forming the slit with a plurality of cuts having a length shorter than a predetermined length, the weight of the packaged object housed in the packaging bag, how to hold the packaging bag, the physique of the user (hand size), etc. The size (expansion range) of the opening of the finger hook to be expanded can be gradually changed according to the above.

In the third aspect, the angle between the pair of slits is 90 ° to 150 °. By setting the angle between the pair of slits in such an angle range, tightening on the user's finger can be reliably suppressed, and moreover, a force sufficient to tighten the user's finger is applied to the finger hook portion. Occasionally, the handle portion is torn from the finger hook portion along the pair of slits, so that the finger hook portion can be reliably expanded.

If the angle between the pair of slits is less than 90 °, even if the tightening force on the finger is small, a part of the handle part will be torn and the finger hook part will be expanded, so the handle part will rather hold it. It becomes difficult. Further, when the angle between the pair of slits exceeds 150 °, even if a tightening force is applied to the finger, a part of the handle portion may not be torn and the finger hook portion may not be expanded.

In the fourth aspect, the closest contact distance between the pair of slits and the finger hook portion is set to 3 mm to 10 mm. Here, the closest distance indicates the closest distance between the pair of slits and the finger hook. By setting the closest contact distance to such a distance range, even when a tightening force is applied to the finger, when the tightening force is small, a part of the handle is not torn and when the tightening force is large. tear. Therefore, when a tightening force that causes the finger to hurt is applied to the finger, a part of the handle portion is torn from the finger hook portion to the slit, and the finger hook portion can be expanded. If the closest contact distance between the pair of slits and the finger hook is less than 3 mm, the handle will be torn even when a slight tightening force is applied to the finger, and if it exceeds 10 mm, a large tightening force will be applied. There is a risk that the handle will not tear even when it touches your finger.

In the fifth aspect, the pair of slits is composed of a pair of first slits and a pair of second slits. By forming the pair of slits with such two types of slits, when a tightening force is applied to the finger, a part of the handle portion can be torn in two stages from the finger hook portion to the pair of slits. Therefore, even if the tightening force applied to the finger differs depending on the weight of the packaged object housed in the packaging bag, how to hold the packaging bag, the user's physique (hand size, finger length), etc., the tightening force is applied. Depending on the size of the opening of the finger rest to be expanded, the size of the opening can be changed.

In the sixth aspect, the end portion of the first slit on the side close to the second slit is formed in a convex shape toward the upper end of the handle portion. By forming the first slit in such a form, when a part of the handle portion is torn from the finger hook portion to the first slit, the torn momentum can be absorbed by the end portion of the first slit. .. Therefore, only when a large tightening force is applied to the finger so that a part of the handle part is torn from the finger hook part to the second slit, the part of the handle part is torn up to the position where the second slit is provided. Can be.

In the seventh aspect, when the notches constituting each slit are a plurality of notches having a length shorter than a predetermined length, the notches are formed by perforations. By forming the pair of slits with such perforations, the perforations are gradually cut according to the tightening force applied to the finger. Therefore, by forming the cuts in each slit with such perforations, the weight of the object to be packaged contained in the packaging bag, how to hold the packaging bag, the physique of the user (the size of the hand), and the like can be determined. The size (expansion range) of the opening of the finger rest to be expanded can be gradually changed.

In the eighth aspect, the finger hook portion is located below the center in the height direction of the handle portion. The center in the height direction of the handle portion is a position L / 2 away from the upper end of the handle portion in the height direction with respect to the width L in the height direction of the handle portion. With this configuration, it is possible to secure an area where the pair of slits is provided above the finger hook portion, so that the formation of the pair of slits becomes easy.

In the ninth aspect, a reinforcing portion is provided above the end portion on the upper end side of the handle portion of the pair of slits. The reinforcing portion can be composed of a fused portion such as a heat seal. By providing such a reinforcing portion, the end portion on the upper end side of the handle portion of the pair of slits is torn, the expansion range of the finger hook portion becomes too large, and the handle portion is broken. Can be prevented.

In the tenth aspect, the reinforcing portion is formed in a convex shape toward the upper end of the handle portion. That is, the reinforcing portion is formed so as to be concave with respect to the slit. When the reinforcing portion has such a shape, it is possible to prevent the handle portion from further breaking from the end portion of the slit along the end portion of the reinforcing portion.

In the eleventh aspect, the reinforcing portion is formed in a straight line extending in the longitudinal direction of the handle portion. With such a configuration, the reinforcing portion can be reliably provided above the end portion on the upper end side of the handle portion of the pair of slits.

In the twelfth aspect, the reinforcing portion is composed of a first reinforcing portion close to the pair of slits and a second reinforcing portion provided at a predetermined distance from the first reinforcing portion. The reinforcing portion composed of such two types of reinforcing portions is in any case of the reinforcing portion formed in a convex shape (9th aspect) and the reinforcing portion formed in a straight line (10th aspect). Can also be adopted. By forming the reinforcing portion with such two reinforcing portions, even if the handle portion is broken at the portion where the first reinforcing portion is formed, the second reinforcing portion prevents the handle portion from further breaking. be able to. Therefore, it is possible to prevent the handle portion from being broken so that the finger cannot be put on the finger hook portion.

According to one aspect of the present invention, it is possible to provide a packaging bag capable of suppressing finger tightening and reducing the burden on the fingers.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a packaging bag according to an example (first embodiment) of the embodiment of the present invention. FIG. 2 is a diagram showing a handle portion of the packaging bag according to the first embodiment. In the description shown below, the parts common to each figure may be designated by the same reference numerals and the description thereof may be omitted.

In FIGS. 1 and 2, the packaging bag 100 includes a bag body 10, a handle 20, a finger hook, and a slit 40. The packaging bag 100 is an example of the packaging bag of the present invention.

As an example of the bag to be packaged, the bag body 10 can accommodate 12 roll-shaped toilet papers T. The bag body 10 is formed of a resin film such as polyethylene or a resin film of a laminate obtained by laminating polyethylene or the like and another resin. The bag body 10 has a structure in which the resin film is formed into a bag shape by a side seal, and the bag-shaped resin film is folded into a gusset shape (see FIG. 1). The bag main body 10 is an example of a main body portion constituting the main body of the packaging bag of the present invention.

The handle 20 constitutes a part of the packaging bag 100 and is made of a resin film or the like like the bag main body 10. The handle 20 is formed at the upper end of the bag body 10 by embossing the resin film folded into the gusset shape with a heat plate for hand molding. The handle 20 has four layers of resin film folded in a gusset shape at both ends in the longitudinal direction of the handle 20 (left-right direction in FIG. 2), and two layers near the center of the handle 20, respectively. It is adhered with a heat seal 50. Further, the handle 20 has an air hole 60 (see FIGS. 6 to 8) communicating with the bag body 10 so that the bag body 10 to which the handle 20 is attached does not explode during the manufacturing or distribution of the packaging bag 100. It is provided. The handle 20 is an example of a handle portion that constitutes a part of the packaging bag of the present invention.

The handle 20 is provided with a finger hook portion 30 for the user P to hook a finger when holding the handle 20 (see FIG. 3). As shown in FIG. 2, the finger hook portion 30 is composed of two finger hook portions 31 and 32 having a shape similar to an elliptical shape or a rectangular shape. The two finger hooks 31 and 32 are located substantially at the center of the handle 20 in the height direction, and are arranged at predetermined intervals in the length direction of the handle 20. The finger hooks 30 (two finger hooks 31, 32) are formed so that the finger of the user P can be hooked when the user P holds the handle 20. The finger hook portion 30 is an example of the finger hook portion provided on the handle portion in the packaging bag of the present invention.

Further, the handle 20 may be provided with a reinforcing film (not shown) that covers the finger hook portion 30. This reinforcing film can be formed of a resin film such as polyethylene. By providing such a reinforcing film, it is possible to reinforce the portion of the handle 20 where the finger hook portion 30 is provided.

Further, the handle 20 is provided with a notch (perforation M1) in advance so that the user P can break the perforation M1 and open it by himself / herself when purchasing the toilet paper T (see FIG. 6). .. After the perforation M1 is broken, the finger hook portion 30 becomes a hole penetrating the handle 20. As shown in FIG. 2, the perforation M1 is not included in a part of the upper end of the periphery of the finger hook portion 30. In this way, the separated portion remains partially connected to the handle 20. When it is completely separated from the handle 20, it is necessary to dispose of the separated part by discarding it, but if the part is kept connected in this way, there is no need to dispose of it.

A slit 40 is formed above the finger hook portion 30. In the first embodiment, as shown in FIG. 2, a pair of slits 41 and 42 are formed as slits 40 above the finger hooks 31 and 32, respectively. The pair of slits 41 and 42 extend from the finger hook portion 30 toward the upper end 21 of the handle 20 so as to extend in the longitudinal direction of the handle 20 (left-right direction in FIG. 2). That is, the pair of slits 41 and 42 extend radially from the finger hook portion 30 toward the upper end 21 of the handle 20.

In the first embodiment shown in FIG. 2, since the slit 40 (a pair of slits 41, 42) is formed above the finger hook portion 30, the user P puts his finger on the finger hook portion 30 of the handle 20. In this state, when the finger of the user P is tightened by the weight of the toilet paper T, a force leading to breakage acts on the portion of the resin film in contact with the finger. As a result, the handle 20 is torn from the finger hook 30 along the pair of slits 41 and 42, and the finger hook 30 is expanded only by the torn handle 20. As a result, when the packaging bag 100 containing the object to be packaged such as toilet paper T is carried, the tightening of the user P to the finger is suppressed (see FIG. 3).

Further, after the handle 20 is torn from the finger hook portion 30 along the pair of slits 41 and 42, a part of the torn handle 20 is interposed between the finger of the user P and the finger hook portion 30. It can function as a cushioning material. Therefore, when the packaging bag is carried in a state where a plurality of roll-shaped toilet paper T or the like is housed, the tightening force (pressure) applied to the finger of the user P can be reduced.

Thus, in the first embodiment shown in FIG. 2, the pressure on the finger of the user P can be relieved. Therefore, when the user P hangs his / her finger on the finger hook portion of the handle 20 and carries the packaging bag in which the object to be packaged is housed, the burden on the finger of the user P can be reduced.

The angle between the pair of slits 41 and 42 is preferably 90 ° to 150 °, more preferably 115 ° to 135 °. By setting the angle between the pair of slits 41 and 42 in such an angle range, it is possible to reliably suppress the tightening of the user P to the finger. Further, when a force enough to strongly tighten the user's finger is applied to the finger hook portion 30, the handle 20 is torn from the finger hook portion 30 along the pair of slits 41 and 42, so that the finger hook portion 30 is reliable. Is extended to.

If the angle between the pair of slits 41 and 42 is less than 90 °, even if the tightening force on the finger is small, a part of the handle part will be torn and the finger hook part will be expanded. It becomes difficult to hold the part. Further, when the angle between the pair of slits 41 and 42 exceeds 150 °, even if a tightening force is applied to the finger, a part of the handle portion may not be torn and the finger hook portion may not be expanded.

In the first embodiment, the closest contact distance between the pair of slits 41 and 42 and the finger hook portion 30 is preferably 3 mm to 10 mm, more preferably 4 mm to 8 mm. By setting the closest distance between the pair of slits 41, 42 and the finger hook portion 30 in such a distance range, when a tightening force is applied to the finger, when the tightening force is small, one of the handle portions is used. The part does not tear and tears when the tightening force increases. Therefore, only when a large tightening force that causes the finger to hurt is applied to the finger, a part of the handle 20 is broken from the finger hook portion 30 to the pair of slits 41 and 42, and the finger hook portion 30 can be expanded. ..

If the closest contact distance between the pair of slits 41, 42 and the finger hook portion 30 is less than 3 mm, the handle 20 is torn even when a slight tightening force is applied to the finger, and if it exceeds 10 mm, the handle 20 is broken. The handle 20 may not be torn even when a large tightening force is applied to the finger.

Further, the pair of slits 41 and 42 are composed of cuts (perforations M2), similarly to the finger hook portion 30. The pair of slits 41, 42 configured by such cuts are cut according to the tightening force applied to the finger of the user P. In the present embodiment, since the notch is particularly composed of the perforation M2, the notch is gradually cut by the tightening force applied to the finger. Therefore, the size of the opening of the finger hook portion 30 depends on the weight of the object to be packaged such as toilet paper T housed in the packaging bag 100, how to hold the packaging bag 100, the physique (hand size) of the user P, and the like. The bag (extension range) changes gradually.

FIG. 4 is a diagram showing a handle portion of a packaging bag according to another example (second embodiment) of the present embodiment. In the second embodiment, the fused portion 70 is provided above the end portions 41a, 42a (the end portion on the upper end 21 side of the handle 20) of the pair of slits 41, 42. The fused portion 70 is arranged as a pair of fused portions 70, 70 with respect to one finger hook portion 30. The fused portion 70 is composed of the same heat seal as the heat seal 50. The fused portion 70 is an example of a reinforcing portion formed on the handle portion of the packaging bag according to the present invention.

Due to the presence of such a fused portion 70, even if the end portions 41a, 42a of the pair of slits 41, 42 are torn when a tightening force is applied to the finger of the user P, the fused portion 70 further breaks. Can be stopped. Therefore, it is possible to prevent the handle 20 from becoming difficult to hold because the expansion range of the finger hook portion 30 becomes too large. Further, when a large tightening force is applied to the finger of the user P, it is possible to prevent the handle 20 from breaking from the end portions 41a, 42a of the pair of slits 41, 42 to the upper end 21 of the handle 20.

Further, the shape of the fused portion 70 is convex toward the upper end 21 of the handle 20. In other words, the fused portion 70 is formed so as to be a recess with respect to the pair of slits 41 and 42. Due to the presence of the fused portion 70 having such a shape, if the tip of the progressive fracture is inside the recess, the tip of the fracture will be the fused portion of the recess even if the traveling direction of the fracture changes slightly. Since they collide with each other, it is possible to prevent the handle 20 from further breaking from the end portions 41a, 42a of the pair of slits 41, 42 along the inner end portion 70a of the fused portion 70.

FIG. 5 is a diagram showing a handle portion of a packaging bag according to another example (third embodiment) of the present embodiment. In the third embodiment, the finger hook portion 30 is arranged below the center of the handle 20 in the height direction (vertical direction in FIG. 5). Further, the fused portion 70 is also arranged lower in accordance with the arrangement position of the finger hook portion 30 as compared with the second embodiment of FIG. By forming the finger hook portion 30 at such a position, it is possible to sufficiently secure a region in which the slit 40 (a pair of slits 41, 42) and the fused portion 70 are provided above the finger hook portion 30. Therefore, the slits 40 (a pair of slits 41, 42) and the fused portion 70 can be easily formed.

FIG. 6 is a diagram showing a handle portion of a packaging bag according to another example (fourth embodiment) of the present embodiment. In the fourth embodiment, the finger hook portion 30 is composed of two finger hook portions having a shape similar to an elliptical shape. Further, the two finger hooks 30 and 30 are arranged so as to be inclined so that the ellipse is substantially symmetrical. In the fourth embodiment, an air hole 60 communicating with the bag body 10 is provided.

In the fourth embodiment, the fused portion 70 is composed of two types of fused portions including a first fused portion 71 and a second fused portion 72. The first fused portion 71 is arranged at a position close to the slits 40 (a pair of slits 41, 42), and the second fused portion 72 sandwiches the first fused portion 71 with the finger hook portion 30. As described above, they are arranged at a predetermined interval with respect to the first fused portion 71. The first fused portion 71 and the second fused portion 72 are examples of the first reinforcing portion and the second reinforcing portion formed on the handle 20 of the packaging bag of the present invention.

By providing such two types of fused portions, even if the handle 20 is broken at the portion where the first fused portion 71 is formed, the handle 20 is further broken by the second fused portion 72. Can be prevented. Therefore, it is possible to prevent the handle 20 from being severely broken so that the handle 20 is difficult to hold or the handle 20 cannot be held.

FIG. 7 is a diagram showing a handle portion of a packaging bag according to another example (fifth embodiment) of the present embodiment. In the fifth embodiment, the finger hook portion 30 is composed of one finger hook portion. Then, in the fifth embodiment, the fused portion 70 is formed in a straight line extending in the longitudinal direction of the handle 20. By arranging the fused portion 70 in such a linear shape, the fused portion 70 serving as a reinforcing portion can be reliably arranged above the ends 41a and 42a of the pair of slits 41 and 42.

FIG. 8 is a diagram showing a handle portion of a packaging bag according to another example (sixth embodiment) of the present embodiment. In the sixth embodiment, the finger hook portion 30 is composed of one finger hook portion, and the finger hook portion 30 is further composed of a linear finger hook portion 30 extending in the longitudinal direction of the handle 20. The linear finger hook portion 30 is also formed by a notch (perforation M1).

In the sixth embodiment, the slit 40 is composed of a pair of slits 41 and 42 (a pair of first slits) and a pair of slits 43 and 44 (a pair of second slits). The pair of first slits 41 and 42 and the pair of second slits 43 and 44 are arranged at predetermined intervals. Specifically, the pair of first slits 41 and 42 are arranged directly above the finger hook portion 30, and the pair of second slits 43 and 44 are above the pair of first slits 41 and 42 (a pair). (In the direction of extension of the notch direction of the first slits 41 and 42). By configuring the slit 40 with such two types of slits (a pair of first slits 41, 42 and a pair of second slits 43, 44), when a tightening force is applied to the finger of the user P, a finger hook is applied. A part of the handle part is torn in two stages from the part to the pair of slits.

For example, when the tightening force to the finger is relatively small, a part of the handle 20 is torn from the finger hook portion 30 to the pair of first slits 41 and 42, and the tightening force to the finger is relatively large. The handle 20 is further torn through the pair of second slits 43 and 44. Therefore, the tightening force applied to the finger depends on the weight of the object to be packaged such as the toilet paper T housed in the packaging bag 100, how to hold the packaging bag 100, the physique of the user P (hand size, finger length), and the like. Even at different times, the size of the opening of the finger rest to be expanded can be changed according to the tightening force.

Further, in the sixth embodiment, the ends 41a, 42a of the pair of first slits 41, 42 (the ends on the side close to the pair of second slits 43, 44) are directed toward the upper end 21 of the handle 20. It is formed in a convex shape. When the ends 41a and 42a of the pair of first slits 41 and 42 are shaped like this, the handle 20 is torn when a part of the handle 20 is torn from the finger hook portion 30 to the pair of first slits 41 and 42. The momentum is absorbed by the ends 41a, 42a of the first slits 41, 42.

That is, in the sixth embodiment, when a tightening force enough to break the handle 20 is applied to the finger from the finger hook portion 30 to the pair of first slits 41, 42, the finger hook portion 30 to the first slits 41, 42 It is possible to prevent the handle 20 from being torn at once up to the position where the pair of second slits 43 and 44 are provided due to the momentum that a part of the handle 20 is torn. Therefore, only when a large tightening force enough to break the handle 20 is applied to the finger from the finger hook portion 30 to the pair of second slits 43, 44, the pair can be held up to the position where the second slits 43, 44 are provided. A part of the hand 20 can be torn.

Hereinafter, embodiments of the present invention will be described with reference to Examples and Comparative Examples.
[Example 1]
As Example 1, the packaging bag 100 of the fourth embodiment shown in FIG. 6 was used. In Example 1, the packaging bag 100 was made of a polyethylene film having a thickness of 25 μm by a bag making machine. In the first embodiment, the finger hooks are composed of two finger hooks 30 and 30 having a shape similar to an elliptical shape. Each finger hook 30 is arranged below the center of the handle 20 in the height direction. A perforation M1 was inserted in each finger hook 30 so as to leave a part of the upper end of the periphery of the finger hook 30. The two finger hooks 30 and 30 are arranged so as to be inclined so that the shape similar to the elliptical shape is substantially symmetrical. Slits 40 (a pair of slits 41 and 42) were formed above the two finger hooks 30, respectively. A fused portion 70 was formed above the ends 41a, 42a (the end on the upper end 21 side of the handle 20) of the pair of slits 41, 42. The fused portion 70 is composed of two types of fused portions (first fused portion 71 and second fused portion 72), and each fused portion 70 is formed so as to be concave with respect to the slit 40. .. In Example 1, the angle between the pair of slits 41 and 42 was set to about 125 °. The closest contact distance between the slits 40 (a pair of slits 41 and 42) and the finger hook portion 30 was set to about 5 mm. The dimensions (in mm units) of each part of the packaging bag 100 of Example 1 are shown in FIG.
[Example 2]

These Examples and Comparative Examples were evaluated by the following test methods.
[Pendulum test]
User P holds two fingers of one hand on the finger hook 30 of the packaging bag 100 containing 12 rolls of toilet paper T (“Eliere Toilet Tissue (single)” manufactured by Daio Paper Corporation). It was moved 10 times back and forth like a pendulum within a range of 180 °. At this time, the durability of the packaging bag 100 was evaluated according to the following criteria. The pendulum test was performed 5 times for each Example and Comparative Example.

◯: No damage was confirmed even once in 5 times ×: Damage was confirmed at least once in 5 times [Finger hook test]
After performing the above pendulum test once, the degree of finger tightening in one user P was evaluated in the following five stages. In this case, the results of the test conducted by 10 people in each of the examples and comparative examples were scored, and the ease of holding was evaluated from the average value according to the following criteria.

5 points: No tightening on fingers 4 points: Very small tightening on fingers 3 points: Small tightening on fingers,
2 points: Tightening to fingers is large 1 point: Tightening to fingers is very large

表１より、指掛部３０の上方に、スリット４０（一対のスリット４１、４２）を設け、一対のスリット４１、４２の端部４１ａ、４２ａの上方に融着部７０を配置した場合（実施例１～実施例３）、持ち易さの試験ではいずれも平均値が３以上となり、ユーザＰの指への締め付けが抑制され、結果となった。また、振り子試験では、いずれも包装袋が破れなかった。

From Table 1, when the slits 40 (a pair of slits 41, 42) are provided above the finger hook portion 30, and the fused portion 70 is arranged above the end portions 41a, 42a of the pair of slits 41, 42 (implementation). In each of Examples 1 to 3) and the ease of holding test, the average value was 3 or more, and the tightening of the user P on the finger was suppressed, resulting in the result. In the pendulum test, the packaging bag was not torn.

On the other hand, in the case where the slits 40 (pair of slits 41, 42) and the fused portion 70 are not arranged above the finger hook portion 30 (Comparative Example 1 and Comparative Example 2), in the easy-to-hold test. In each case, the average value was less than 3, resulting in a large tightening of the user P on the finger. Moreover, in each of the pendulum tests, the handle 20 of the packaging bag 100 was torn.

From these results, the packaging bag 100 provided with a pair of slits 41, 42 extending in the longitudinal direction of the handle 20 from the finger hook portion 30 toward the upper end 21 of the handle 20 is the finger of the user P.
