A bag is disclosed.

Japanese Patent No. 4856412 JP-A-2004-269010

  However, in the conventional packaging bag, the fingers are tightened or the hands are hurt at the time of carrying, depending on the weight and bulk of the packaged object stored in the packaging bag, the way of holding the packaging bag in which the packaged object is stored, and the like. May be. Further, when the packaging bag is carried, a change in the shape of the finger hook portion may cause the handle portion to stretch or break. For this reason, the packaging bag may be difficult to hold while the packaged object is stored, and the packaging bag may be damaged when being carried.

  An object of the present invention is to provide a packaging bag which is easy to hold and is not easily damaged.

  A first aspect according to the present invention has a main body for housing an object to be packaged, and a handle provided on an upper portion of the main body, and a central portion in a longitudinal direction of the handle, Provided is a packaging bag, wherein two slits extending along a longitudinal direction are formed side by side in a height direction of the handle.

  In this specification, “extending along the longitudinal direction of the handle” includes both cases where the slit is parallel to the longitudinal direction of the handle and cases where the slit is not parallel. The shape of the slit is not particularly limited, and may be any of a straight line, a curved line, a wavy line, and the like. Further, that two slits are arranged in the height direction of the handle portion means that the two slits are arranged to face each other in the height direction of the handle portion.

  In the first aspect, since the two slits extending along the longitudinal direction of the handle portion are formed side by side in the height direction of the handle portion, any one of the two slits is provided. A finger or palm (hereinafter referred to as a finger or the like) can be put into the device. Further, by inserting a finger or the like inserted in the one slit into one of the other slits, a portion formed between the two slits becomes a finger hook portion, and this portion can be grasped with a finger or the like.

  Further, when a portion formed between the two slits (hereinafter, also referred to as a finger hook portion) is gripped by a finger or the like, the finger hook portion can hit the finger or the like in a plane. In other words, it becomes difficult for the finger hook portion to hit a finger or the like as a line. Thereby, even if the grip portion is lifted by grasping the finger hook portion, the finger hook portion hits the finger or the like in a plane (does not hit as a line), and the finger portion or the like is tightened by the hand grip portion or the finger is hurt. Can be suppressed. Therefore, when carrying a packaging bag in the state where the to-be-packaged object was accommodated, it becomes easy to hold a packaging bag.

  Further, in the first aspect, the finger hook portion hits the surface of the finger or the like (it is hard to hit as a line), so that the finger hook portion is not easily deformed when the packaging bag is carried. Thus, when the handle is lifted, the finger hook or a part of the handle excluding the finger hook can be prevented from being stretched or broken. Therefore, when carrying the packaging bag in a state where the packaged object is stored, the packaging bag is less likely to be damaged.

  In a second aspect according to the present invention, the two slits include a first slit disposed at a lower end of the handle, and a second slit disposed at an upper end of the handle. A packaging bag is provided in which the first slit and the second slit are arranged at a predetermined interval in the height direction.

  In this specification, the distance between the first slit and the second slit indicates the distance between the first slit and the second slit. The arrangement of the first slit and the second slit at a predetermined interval means that the distance between the first slit and the second slit has a certain range of distance. The distance between the first slit and the second slit is preferably a distance at which a portion (finger hook) formed between the two slits can be grasped with a finger or the like, and more preferably a finger hook. Is the distance at which the finger hook does not break when is gripped with a finger or the like.

  In the second aspect, since the two slits are arranged at a predetermined interval in the height direction of the handle as described above, it is possible to reliably form the finger hook that hits the finger or the like with a surface. . Therefore, a packaging bag which is easy to hold and is not easily damaged can be reliably obtained.

  A third aspect according to the present invention provides a packaging bag, wherein at least one of the first slit and the second slit curves so as to be away from the other of the first slit and the second slit. I do.

  In this specification, at least one of the first slit and the second slit is curved when only the first slit is curved, when only the second slit is curved, or when the first slit and the second slit are curved. Also mean the case where it is curved. In addition, the term “away from one of the first slit and the second slit” means that when the first slit is curved, the first slit is curved so as to be convex in a direction in which the distance to the second slit becomes longer. In the case where the second slit is curved, it indicates that the second slit is curved so as to be convex in a direction in which the distance from the first slit becomes longer.

  In the third aspect, when the first slit and / or the second slit curves away from the second slit and / or the first slit in this manner, when viewed in the height direction of the handle portion, The width at the center of the finger hook is larger than the width at both ends of the finger hook. Accordingly, in the third aspect, the area of the finger hook portion that comes into contact with the finger or the like can be increased, so that the packaging bag can be more easily held.

  A fourth aspect according to the present invention provides a packaging bag, wherein at least one of the first slit and the second slit curves so as to approach one of the other of the first slit and the second slit. I do. In the present specification, the term “close to one of the first slit and the second slit” means that when the first slit is curved, the first slit is convex in a direction in which the distance from the second slit becomes shorter. When the second slit is curved, it indicates that the second slit is curved so as to be convex in a direction in which the distance from the first slit becomes shorter.

  In the fourth aspect, when the first slit and / or the second slit curves in such a manner as to approach the second slit and / or the first slit, when viewed in the height direction of the handle portion, In addition, the width of both ends of the finger hook is larger than the width of the center of the finger hook. In addition, since both end portions of the finger hook portion constitute a connecting portion with the handle portion, the finger hook portion tends to be easily broken. On the other hand, in the fourth aspect, since the finger hooks whose widths at both ends are larger than the width at the center are thus formed, both ends of the finger hooks are not easily broken. . For this reason, a packaging bag that is harder to break can be obtained.

  A fifth aspect according to the present invention provides a packaging bag, wherein at least one of the first slit and the second slit has an elliptical shape. In the present specification, having an elliptical shape means that the contour shape of the first slit and / or the second slit when viewed in the thickness direction of the handle portion is an elliptical shape.

  In the fifth aspect, by forming the first slit and / or the second slit into an elliptical shape in this manner, it becomes easy for a finger or the like to enter the first slit and / or the second slit formed into an elliptical shape. In addition, when viewed in the height direction of the handle, the width of the both ends of the finger hook is larger than the width of the center of the finger hook that hits the surface of the finger, etc. A packaging bag that is hard to break is obtained.

  According to a sixth aspect of the present invention, there is provided a packaging bag, wherein the second slit is disposed at a central portion in the height direction. In this specification, the central portion in the height direction of the handle portion indicates a region including the center in the height direction of the handle portion and the vicinity or periphery of the center.

  In the sixth aspect, by arranging the second slit at the center in the height direction of such a handle, a portion (finger hook) formed between the first slit and the second slit is formed. The lower end of the handle portion can be formed. In addition, the handle portion tends to be easily cut upward from the finger hook portion. On the other hand, in the sixth aspect, since the margin of the handle portion (portion where the slit of the handle portion is not formed) is sufficiently (or in a wide range) above the finger hook portion, the finger hook is provided. Breaking of the handle portion from the portion toward the upper end of the handle portion can be prevented.

  A seventh aspect according to the present invention provides a packaging bag, wherein the two slits are surrounded by a seal portion formed on the handle portion. Here, the seal portion may be a reinforcing portion for reinforcing the handle portion. Therefore, the finger hook formed on the handle is surrounded by the seal (reinforcement). In the seventh aspect, by surrounding the two slits with such a reinforcing portion, it is possible to reliably prevent the handle portion from being broken starting from the finger hook portion.

  According to one embodiment of the present invention, a packaging bag which is easy to hold and is not easily damaged can be provided.

  FIG. 1 shows a packaging bag 100 according to an embodiment of the present invention. FIG. 2 shows a handle portion 20 of the packaging bag 100 according to the present embodiment (first embodiment). 1 and 2, the packaging bag 100 includes a main body 10 and a handle 20. Note that the packaging bag 100 is an example of the packaging bag of the present invention, and the main body 10 and the handle 20 are examples of the main body and the handle constituting the packaging bag of the present invention.

  The main body 10 constitutes a main body (bag main body) of the packaging bag 100 in which the packaged object T is stored. The main body 10 can be formed of a resin film or the like. The main 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 material of the resin film forming the main body 10 is arbitrary. As such a resin film, for example, a resin film such as a polyethylene (PE) or a laminate of PE-ethylene vinyl alcohol copolymer (EVOH) -PE (PE / EVOH / PE) can be used. Further, the thickness of the resin film is arbitrary. For example, when PE or PE / EVOH / PE is used as the resin film, the thickness of the resin film can be 10 to 70 μm, preferably 15 to 60 μm, and more preferably 20 to 50 μm.

  The main body 10 accommodates twelve roll-shaped toilet papers as an example of the packaged object T (see FIG. 1). The form of the packaged body is not limited to a roll shape, and may be accommodated in another form such as a laminated shape. Further, the packaged body accommodated in the main body 10 is not limited to toilet paper, but can accommodate articles such as kitchen paper, baby or nursing disposable diapers, and sanitary napkins.

  Furthermore, the number of articles stored in the main body 10 is not limited. That is, the number of articles to be stored may be one, or may be plural as shown in FIG. In the example shown in FIG. 1, 12 roll-shaped toilet papers (packaged objects T) are accommodated in the main body 10 in a state where four rolls are arranged in one row and stacked in three rows. However, the arrangement of the packages to be accommodated in the main body 10 is not limited to this arrangement. For example, the body 10 is arranged in a state where twelve toilet papers (packs T) are arranged in one step. May be accommodated.

  As shown in FIG. 1, the handle portion 20 is provided on the upper portion 11 of the main body portion 10 and constitutes a portion for gripping the packaging bag 100 with fingers or the like. The shape of the handle portion 20 is not particularly limited. For example, the contour shape of the handle portion 20 when viewed in the thickness direction (Z direction) can be a rectangle such as a rectangle.

  The size of the handle portion 20 is not particularly limited, and can be determined by the size of the main body portion 10, the size of a slit described later, and the like. When the shape of the handle portion 20 is rectangular, the size of the handle portion 20 can be, for example, 150 to 500 mm in the longitudinal direction (X direction) of the handle portion 20, and preferably 160 to 500 mm. It is 400 mm, more preferably 170 to 300 mm. In addition, the dimension of the handle portion 20 in the height direction (Y direction) can be 35 to 150 mm, preferably 40 to 130 mm, and more preferably 45 to 100 mm.

  The handle portion 20 can be formed of a resin film or the like, similarly to the main body portion 10. The handle 20 is formed on the upper portion 11 of the main body 10 by heat sealing (heat sealing). The position where the handle portion 20 is provided is not limited to the upper portion 11 of the main body portion 10, and may be a side surface of the main body portion 10. For the heat sealing (heat sealing), for example, a method (stamp method) of embossing the above-mentioned gusset-shaped resin film with a hot plate for holding molding can be used.

  The handle portion 20 is formed by stacking four folded resin films at both ends 23 and 24 in the longitudinal direction (X direction) of the handle portion 20, and at the center of the handle portion 20 in the longitudinal direction (X direction). In the vicinity of the portion 25, two sheets are stacked and bonded by a seal portion 50 formed by heat sealing (heat fusion). Note that the seal portion 50 is not limited to the heat fusion, and may be formed by applying an adhesive, an adhesive, or the like.

  As shown in FIG. 2, the seal portion 50 includes an upper end seal 51, a lower end seal 52, a side end seal 53, and a side end seal 54. The upper end seal 51 is provided on the upper end 22 of the handle 20. The lower end seal 52 is provided at the lower end 21 of the handle 20. The side end seal 53 is provided on the end 23 side of the handle portion 20 in the longitudinal direction (X direction). The side end seal 54 is provided on the end 24 side of the handle portion 20 in the longitudinal direction (X direction).

  As a result, the seal portion 50 (seals 51 to 54) is formed inside the handle portion 20. The portion surrounded by the seals 51 to 54 constitutes a central portion 25 of the handle portion 20 in the longitudinal direction (X direction). It should be noted that the handle portion 20 has an air hole (not shown) that allows the body portion 10 and the outside of the packaging bag 100 to communicate with each other so that the body portion 10 to which the handle portion 20 is attached does not burst during manufacturing or distribution of the packaging bag 100. (Not shown) is preferably provided.

  As shown in FIGS. 1 and 2, two slits 30 and 40 are formed in a central portion 25 of the handle portion 20 in the longitudinal direction (X direction). Each of the two slits 30 and 40 extends along the longitudinal direction (X direction) of the handle portion 20 and is arranged side by side in the height direction (Y direction) of the handle portion 20. The form of the slit is not particularly limited. For example, the slit can be formed at a perforation, and the slit can be formed by breaking the perforation.

  Here, as an aspect extending along the longitudinal direction (X direction) of the handle part 20, there are cases where the slits 30 and 40 are parallel to the longitudinal direction (X direction) of the handle part 20 and cases where they are not parallel. obtain. The shape of the slits 30 and 40 is not particularly limited, and may be any of a straight line, a curved line, a wavy line, and the like. Further, that the two slits 30 and 40 are arranged in the height direction (Y direction) of the handle portion 20 means that the two slits 30 and 40 face each other in the height direction (Y direction) of the handle portion 20. Indicates that it is.

  In the present embodiment, as shown in FIGS. 1 and 2, the two slits 30 and 40 are formed on the first slit 30 disposed on the lower end 21 side of the handle 20 and on the upper end 22 side of the handle 20. The second slit 40 is arranged. The first slit 30 and the second slit 40 extend linearly in the longitudinal direction (X direction) of the handle portion 20 and are formed in parallel with the height direction (Y direction) of the handle portion 20. . The first slit 30 and the second slit 40 are arranged at a predetermined interval in the height direction (Y direction).

  Here, the distance between the first slit 30 and the second slit 40 indicates a distance d between the first slit 30 and the second slit 40 (see FIG. 2). Further, that the first slit 30 and the second slit 40 are arranged at a predetermined interval means that the distance d between the first slit 30 and the second slit 40 has a certain range of distance. means.

  Note that the distance d is preferably a distance by which a portion (finger hook portion FH) formed between the two slits 30 and 40 can be gripped by a finger or the like, and when the finger hook portion FH is gripped by a finger or the like. It is more preferable that the distance is such that the finger hook does not break. Such a distance d is preferably 10 to 35 mm, more preferably 12 to 30 mm, and still more preferably 13 to 20 mm.

  In the present embodiment, as shown in FIGS. 1 and 2, the second slit 40 is disposed at the central portion 26 in the height direction (Y direction). Here, the central portion 26 in the height direction (Y direction) of the handle portion 20 refers to a region including the center of the handle portion 20 in the height direction (Y direction) and the vicinity or periphery of the center. By arranging the second slit 40 in the central portion 26 in the height direction (Y direction) of the handle portion 20 in this manner, a portion (finger) formed between the first slit 30 and the second slit 40 is formed. The hook portion FH) is formed near the lower end 21 of the handle portion 20.

  In the present embodiment, as shown in FIG. 2, the two slits 30 and 40 are surrounded by a seal portion 50 formed on the handle portion 20. Specifically, the central portion 25 in the longitudinal direction (X direction) of the handle portion 20 in which the first slit 30 and the second slit 40 are formed is a part of the upper end seal 51, a part of the lower end seal 52, It is surrounded by end seals 53 and 54.

  Further, the handle portion 20 may be provided with a reinforcing film (not shown). This reinforcing film can be formed of a resin film. The material of the reinforcing film is arbitrary, and may be the same as or different from the material of the resin film constituting the handle portion 20. As such a resin film, for example, a laminate (PE / EVOH / PE) of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and PE-ethylene vinyl alcohol copolymer (EVOH) -PE And the like. By providing such a reinforcing film, it is possible to reinforce the central portion 25 in the longitudinal direction (X direction) of the handle portion 20 where the first slit 30 and the second slit 40 are formed.

  Further, the thickness dimension of the reinforcing film is arbitrary. For example, the thickness of the reinforcing film can be 20 μm or more, preferably 30 μm to 150 μm, more preferably 50 μm to 130 μm. By setting the thickness dimension of the reinforcing film in such a range, the handle portion 20 can be prevented from being stretched or broken. In addition, the reinforcing film can be bonded to the handle portion 20 at the time of forming the seal portion 50 by the above-described heat welding or the like.

  FIG. 3 to FIG. 5 are views showing a usage mode of the packaging bag 100 according to the present embodiment. Here, the effects of the present embodiment will be described with reference to FIGS. In the first embodiment, as described above, the two slits 30 and 40 extending along the longitudinal direction (X direction) of the handle 20 are formed side by side in the height direction (Y direction) of the handle 20. Have been. Therefore, a finger or a palm (hereinafter referred to as a finger or the like P) can be inserted into one of the two slits 30 and 40.

  Specifically, as shown in FIGS. 3 and 4, the finger P or the like can be inserted through the second slit 40, and the finger P or the like inserted into the second slit 40 can be further inserted into the first slit 30. Then, as shown in FIG. 5, a portion formed between the two slits 30 and 40 can be a finger hook FH. The finger hook FH can be grasped with a finger P or the like (see FIG. 5).

  In this state, a portion formed between the two slits 30 and 40 (hereinafter, may be abbreviated as a finger hook FH) can hit the finger P or the like in a plane. That is, it becomes difficult for the finger hooking portion to hit a finger or the like as a line. As a result, even if the grip portion FH is grasped and the handle portion 20 is lifted, the finger portion FH hits the finger or the like P in a plane (does not hit as a line). It can be suppressed that the finger P or the like becomes painful (see FIG. 5). Therefore, when carrying the packaging bag 100 in a state where the packaged object T is stored, the packaging bag 100 becomes easy to hold.

  In addition, in the examples shown in FIGS. 3 to 5, the mode in which the finger or the like P is inserted from the second slit 40 has been described, but the present invention is not limited to this mode. Therefore, by inserting a finger or the like P from the first slit 30 and further into the second slit 40, a portion formed between the two slits 30 and 40 may be grasped as the finger hook FH.

  Further, in the present embodiment, a finger or the like P is inserted into only one of the first slit 30 and the second slit 40 without putting the finger or the like P into both the first slit 30 and the second slit 40 and the hand is held. The part 20 can also be grasped. In this case, if a finger or the like P is inserted only into the first slit 30 disposed on the lower end 21 side of the handle 20 and the handle 20 is grasped, the finger hook FH strikes the finger or the like P as a line. Due to the presence of the second slit 40 formed on the upper end 22 side of the handle portion 20, the handle portion 20 is deformed and softened while being gripped by the finger P or the like.

  Therefore, even if the finger P is not put in both the first slit 30 and the second slit 40 as in the examples shown in FIGS. Thus, from the viewpoint of the packaging bag 100 of the present embodiment, it can be said that the way of holding the handle portion 20 is not limited.

  Further, in the present embodiment, the finger hook FH is easy to hit the surface of the finger P or the like (hard to hit as a line), so that the finger hook FH is not easily deformed when the packaging bag 100 is carried. Thus, when the handle portion 20 is lifted, the finger hook portion FH or a part of the handle portion 20 excluding the finger hook portion FH can be prevented from being stretched or broken (see FIG. 5). . Therefore, when carrying the packaging bag 100 in a state where the packaged object T is accommodated, the packaging bag 100 is less likely to be damaged.

  Further, in the present embodiment, as described above, the two slits 30 and 40 are arranged at predetermined intervals in the height direction (Y direction) of the handle 20. That is, the distance d between the first slit 30 and the second slit 40 has a certain range of distance. Therefore, it is possible to reliably form the finger hooking portion FH which is in contact with the finger P or the like. Therefore, the packaging bag 100 which is easy to hold and hard to break can be reliably obtained.

  Note that the handle portion 20 tends to be easily cut upward from the finger hook portion FH. On the other hand, in the present embodiment, as described above, the portion (finger hook FH) formed between the first slit 30 and the second slit 40 may be formed near the lower end 21 of the handle 20. it can. Thus, in the present embodiment, since the portion of the handle portion 20 where the slit is not formed (the margin M of the handle portion 20) is sufficiently (or in a wide range) above the finger hook portion FH, the finger is Breakage of the handle portion 20 from the hook portion FH toward the upper end 22 of the handle portion 20 can be prevented.

  In the present embodiment, as described above, the two slits 30 and 40 are surrounded by the seal portion 50 (part of the upper end seal 51, part of the lower end seal 52, and side end seals 53 and 54). Since the seal portion 50 can be a reinforcing portion for reinforcing the handle portion, the finger hook portion FH formed on the handle portion is surrounded by the seal portion 50 (reinforcement portion). Thereby, it is possible to reliably prevent the handle portion 20 from breaking from the finger hook portion FH in the central portion 25 in the longitudinal direction (X direction) of the handle portion 20.

  Note that the handle portion 20 may be provided with another seal portion (not shown) in addition to the seal portion 50. Such another seal portion is preferably formed, for example, above the second slit 40, and specifically, between the upper end 22 (or upper end seal 51) of the handle portion 20 and the second slit 40. It is preferable to form so as to extend continuously from the side end seal 53 to the side end seal 54. By providing such another seal portion, it is possible to reliably prevent the handle portion 20 from breaking from the finger hook portion FH toward the upper end 22 of the handle portion 20.

  Further, such another seal portion (not shown) is provided in addition to the case where it is formed above the second slit 40 described above, or in place of the case where it is formed above the second slit 40, and It may be formed between 30 and the second slit 40. Specifically, it is preferable to form between the first slit 30 and the second slit 40 so as to extend continuously from the side end seal 53 to the side end seal 54.

  By providing another seal portion between the first slit 30 and the second slit 40 in this manner, the finger hook portion FH formed between the first slit 30 and the second slit 40 is made a stable surface. It can be grasped with fingers P or the like. Further, another seal portion provided between the first slit 30 and the second slit 40 can reinforce the finger hook portion FH itself, so that the finger hook portion FH is more difficult to be broken.

  FIG. 6 shows the handle 20 of the packaging bag 100 according to the present embodiment (second embodiment). In the second embodiment, at least one of the first slit 30 and the second slit 40 is curved away from the other of the first slit 30 and the second slit 40. Here, the mode in which at least one of the first slit 30 and the second slit 40 is curved includes a case where only the first slit 30 is curved, a case where only the second slit 40 is curved, or a case where the first slit 30 is curved. Each of the second slits 40 may be curved.

  In addition, the term “away from one of the first slit 30 and the second slit 40” means that when the first slit 30 is curved, the first slit 30 becomes convex in a direction in which the distance d to the second slit 40 becomes longer. This shows that the slit 30 is curved. Further, when the second slit 40 is curved, it indicates that the second slit 40 is curved so as to be convex in a direction in which the distance d from the first slit 30 becomes longer.

  In the packaging bag 100 of the second embodiment, as shown in FIG. 6, both the first slit 30 and the second slit 40 are curved. The first slit 30 is curved so as to be convex in a direction in which the distance d with the second slit 40 is long, and the second slit 40 is convex in a direction in which the distance d with the first slit 30 is long. It is curved to become. Specifically, when viewed in the height direction (Y direction) of the handle portion 20, the width dimension d1 of the central portion C of the finger hook portion FH is equal to the end portion E1 and the end portion E2 of the finger hook portion FH. (See FIG. 6).

  Here, the central portion C of the finger hook portion FH is a portion between the central portion 31 of the first slit 30 and the central portion 41 of the second slit 40. The end E1 of the finger hook FH is a portion between the end 32 of the first slit 30 and the end 42 of the second slit 40. The end E2 of the finger hook FH is a portion between the end 33 of the first slit 30 and the end 43 of the second slit 40.

  When the width d1 of the center C of the finger hook FH is larger than the width d2 of the ends E1 and E2 of the finger hook FH, the width d1 of the center C of the finger hook FH is , Preferably 12 to 40 mm, more preferably 14 to 35 mm, and still more preferably 15 to 30 mm. Further, the width dimension d2 of the end E1 and the end E2 of the finger hook FH is preferably 10 to 35 mm, more preferably 12 to 30 mm, and further preferably 13 to 25 mm.

  In the second embodiment, the first slit 30 and the first slit 30 are formed such that the width dimension d1 of the central portion C of the finger hook portion FH is larger than the width dimension d2 of the end portion E1 and the end portion E2 of the finger hook portion FH. A second slit 40 is formed in the handle portion 20. Thus, the area of the finger hook FH that comes into contact with the finger P or the like can be increased, so that the packaging bag 100 can be more easily held.

  FIG. 7 shows the handle 20 of the packaging bag 100 according to the present embodiment (third embodiment). In the third embodiment, at least one of the first slit 30 and the second slit 40 is curved so as to approach one of the other of the first slit 30 and the second slit 40.

  Here, approaching either one of the first slit 30 and the second slit 40 means that when the first slit 30 is curved, the first slit 30 is convex in the direction in which the distance d from the second slit 40 becomes shorter. This shows that one slit 30 is curved. Also, when the second slit 40 is curved, it indicates that the second slit 40 is curved so as to be convex in a direction in which the distance d from the first slit 30 becomes shorter.

  In the packaging bag 100 of the third embodiment, as shown in FIG. 7, both the first slit 30 and the second slit 40 are curved.

Further, the width dimension d2 of the end E1 and the end E2 of the finger hook FH is preferably 12 to 40 mm, more preferably 14 to 35 mm, and still more preferably 15 to 30 mm.

  In addition, since both ends E1 and E2 of the finger hook portion FH formed in this way constitute a connecting portion with the handle portion 20, they tend to be easily broken. On the other hand, in the third embodiment, since the finger hooks FH in which the width d2 of the both ends E1 and E2 are larger than the width d1 of the center C are formed, the both ends E1 and E2 of the finger hook FH are formed. E2 is less likely to break. Therefore, the packaging bag 100 which is harder to break can be obtained.

  FIG. 8 shows the handle 20 of the packaging bag 100 according to the present embodiment (fourth embodiment). In the fourth embodiment, at least one of the first slit 30 and the second slit 40 has an elliptical shape.

For example, the first slit 30 and the second slit 40 have a major axis (length of the major axis of the ellipse) in the longitudinal direction (X direction) of the handle portion 20. It is preferable that the handle portion 20 has an elongated elliptical shape having a minor axis (the length of the minor axis of the ellipse) in the height direction (Y direction).

  Here, the dimension of the major axis of the elliptical shape of the first slit 30 and the second slit 40 is preferably 70 to 90 mm, more preferably 72 to 88 mm, and still more preferably 75 to 85 mm. Further, the dimension of the minor axis of the elliptical shape of the first slit 30 and the second slit 40 is preferably 1 to 7 mm, more preferably 2 to 6 mm, and still more preferably 3 to 5 mm.

  When the first slit 30 and the second slit 40 have an elliptical shape, the width dimension d1 of the central portion C of the finger hook FH is preferably 10 to 35 mm, more preferably 12 to 30 mm, and furthermore Preferably it is 13 to 25 mm. Further, the width dimension d2 of the end E1 and the end E2 of the finger hook FH is preferably 12 to 40 mm, more preferably 14 to 35 mm, and still more preferably 15 to 30 mm.

  In the fourth embodiment, by forming the first slit 30 and / or the second slit 40 into an elliptical shape in this way, the first slit 30 and / or the second slit 40 formed into an elliptical shape have fingers P or the like. Can be easily inserted. In addition, when viewed in the height direction (Y direction) of the handle portion 20, both ends of the finger hook portion FH correspond to the width dimension d1 of the center portion C of the finger hook portion FH which hits the surface of the finger P or the like. Since the width dimension d2 of the portions E1 and E2 is increased, the packaging bag 100 that is harder to break can be obtained.
