And a packaging bag having a part.

本明細書において、弾性部材とは、外力を加えると変形し、外力を除くと元の状態に戻ることが可能な部材を示す。弾性部材の形態は、特に限定されず、プレート、シート、フィルム、フィルムまたはシートを複数枚積層したもの等が挙げられる。 In the present specification, the elastic member refers to a member that is deformable when an external force is applied and can return to the original state when the external force is removed. The form of the elastic member is not particularly limited, and examples thereof include a plate, a sheet, a film, and a laminate of a plurality of films or sheets.

弾性部材の材質は、特に限定されず、ポリエチレンエラストマー、ポリイソブチレンエラストマー等の熱可塑性エラストマー、スチレン−ブタジエンゴム、ブタジエンゴム、イソプレンゴム、クロロプレンゴム等の汎用ゴム、ウレタンゴム、シリコーンゴム等が挙げられる。 The material of the elastic member is not particularly limited, and examples thereof include thermoplastic elastomers such as polyethylene elastomer and polyisobutylene elastomer, general-purpose rubbers such as styrene-butadiene rubber, butadiene rubber, isoprene rubber, chloroprene rubber, urethane rubber, and silicone rubber. ..

また、持手部の中央領域とは、持手部の略中央で持手部全体の３分の１程度を占める部分を示す。なお、少なくとも持手部の中央領域に形成されるとは、弾性部材が持手部の中央領域のみに形成される場合、弾性部材が持手部の中央領域と中央領域以外の領域に形成されている場合のいずれでもよいことを示す。 In addition, the central region of the handle portion indicates a portion which is approximately the center of the handle portion and occupies about one third of the entire handle portion. Note that at least in the central region of the handle part means that when the elastic member is formed only in the central region of the handle part, the elastic member is formed in the central region of the handle part and regions other than the central region. It indicates that any of the above is acceptable.

また、第２開口部が第１開口部に重なるとは、第２開口部の全部が第１開口部の全部と重なる場合、第２開口部の全部が第１開口部の一部と重なる場合、第２開口部の一部が第１開口部の全部と重なる場合、第２開口部の一部が第１開口部の一部と重なる場合のいずれでもよいことを示す。 In addition, when the second opening overlaps the first opening, it means that the second opening entirely overlaps the first opening, or the second opening partially overlaps the first opening. , Where a part of the second opening overlaps with the entire first opening and a part of the second opening overlaps with the first opening.

第１開口部および第２開口部の各形態は、限定されず、スリット、貫通孔等で形成することができる。また、第１開口部または第２開口部を構成するスリット、貫通孔等は、持手部に形成されたミシン目を破ることで形成してもよい。 Each form of the first opening and the second opening is not limited and can be formed by a slit, a through hole, or the like. Further, the slits, the through holes, etc. forming the first opening portion or the second opening portion may be formed by breaking the perforations formed in the handle portion.

第１の態様では、持手部の中央領域に弾性部材が形成され、該中央領域に形成された第１開口部に対して弾性部材に形成された第２開口部が重なることで、第１開口部および第２開口部に手指または掌（以下、手指等という）を挿入する（通すまたは入れる）ことができる。そして、該挿入した手指等で持手部を掴む（または握る）ことができる。そのため、第１開口部および第２開口部は、持手部の指掛部を構成することができる。 In the first aspect, the elastic member is formed in the central region of the handle portion, and the second opening formed in the elastic member overlaps the first opening formed in the central region, whereby the first member is formed. Fingers or palms (hereinafter referred to as fingers) can be inserted (passed or inserted) into the openings and the second openings. Then, the holding portion can be grasped (or grasped) by the inserted fingers or the like. Therefore, the first opening portion and the second opening portion can form a finger hook portion of the handle portion.

また、第１の態様では、第１開口部および第２開口部（指掛部）に該手指等を入れて持手部を掴む（または握る）と、第２開口部が形成された弾性部材の一部（第２開口部の上方部分）を掴むことができる。そして、持手部に形成された弾性部材は、持手部を掴んだときに生じた外力により変形し、手指等にかかる圧力を吸収することができる。 Further, in the first aspect, when the fingers and the like are put into the first opening portion and the second opening portion (finger hooking portion) and the holding portion is grasped (or grasped), the elastic member having the second opening portion is formed. It is possible to grasp a part (upper part of the second opening) of the. Then, the elastic member formed on the handle portion is deformed by the external force generated when the handle portion is gripped, and the pressure applied to the finger or the like can be absorbed.

また、第１の態様では、弾性部材が持手部を掴んだ手指等の状態に合わせて形状が変化する（または弾性部材が伸び縮みする）。言い換えると、弾性部材は、持手部を掴んだ（または握った）ときに手指等に馴染んだ形で当たる（フィットする）。そのため、持手部の中央領域に弾性部材が形成された持手部は、安定した状態で掴む（または握る）ことができる。 In addition, in the first aspect, the shape of the elastic member changes (or the elastic member expands and contracts) in accordance with the state of the finger or the like holding the grip portion. In other words, the elastic member hits (fits) in a form that is familiar to fingers and the like when gripping (or gripping) the handle portion. Therefore, the grip portion having the elastic member formed in the central region of the grip portion can be gripped (or gripped) in a stable state.

また、弾性部材は保形性を有するため、持手部を掴んだときに持手部に形成された弾性部材の一部（上方部分）が、手指等に対して面状に当たりやすくなる。言い換えると、持手部に設けられた弾性部材の一部分は、手指等に対して線状に当たりにくくなる。 In addition, since the elastic member has a shape-retaining property, a part (upper part) of the elastic member formed on the holding portion when the holding portion is gripped is likely to hit a finger or the like in a planar manner. In other words, it is difficult for a part of the elastic member provided on the handle portion to linearly contact a finger or the like.

このような構成により、第１の態様では、持手部を掴んだ際に手指等にかかる負荷を和らげる（または緩和する）ことができる。そのため、持手部によって手指等が締め付けられたり、手指等が痛くなるのを抑制することができる。これにより、第１の態様では、持手部が掴みやすく（または握りやすく）なり、包装袋の持ち運びが容易になる。 With such a configuration, in the first aspect, it is possible to alleviate (or alleviate) the load applied to the fingers and the like when gripping the handle portion. Therefore, it is possible to prevent the fingers and the like from being tightened by the handle portion and the fingers and the like from being hurt. Accordingly, in the first aspect, the handle portion is easily grasped (or easily grasped), and the packaging bag is easily carried.

また、第１の態様では、第１開口部を覆う弾性部材が持手部の中央領域に形成されているため、弾性部材が持手部の中央領域（持手部の指掛部が構成される部分）を補強することができる。また、このような弾性部材により、上述のように手指等にかかる圧力が吸収され、また、持手部を安定した状態で掴める（または握れる）ことで、持手部が伸びたり、破断するのを抑制することができる。これにより、第１の態様では、被包装体が収容された状態で包装袋を持ち運ぶ場合に、包装袋が破損しにくくなる。 Further, in the first aspect, since the elastic member that covers the first opening is formed in the central region of the handle part, the elastic member forms the central region of the handle part (the finger hook part of the handle part is configured. Part) can be reinforced. In addition, the elastic member absorbs the pressure applied to the fingers and the like as described above, and by gripping (or grasping) the handle part in a stable state, the handle part is extended or broken. Can be suppressed. Accordingly, in the first aspect, when the packaging bag is carried while the packaged object is accommodated, the packaging bag is less likely to be damaged.

本発明に係る第２の態様は、前記第２開口部の幅が、前記第１開口部の幅より短い、包装袋である。本明細書において、第１開口部の幅は、持手部の長手方向における第１開口部の長さ（横幅）を示し、第２開口部の幅は、該長手方向における第２開口部の長さ（横幅）を示す。なお、第２開口部が第１開口部に重なる部分は、持手部の指掛部を構成する観点から、第１開口部の幅の約３０％以上を占める部分となることが好ましい。 A second aspect according to the present invention is a packaging bag in which the width of the second opening is shorter than the width of the first opening. In the present specification, the width of the first opening indicates the length (lateral width) of the first opening in the longitudinal direction of the handle portion, and the width of the second opening is the width of the second opening in the longitudinal direction. Indicates the length (width). It is preferable that the portion where the second opening overlaps the first opening is a portion that occupies about 30% or more of the width of the first opening from the viewpoint of forming the finger hook of the handle.

第２の態様では、弾性部材に形成された第２開口部の幅が、持手部（中央領域）に形成された第１開口部の幅より短いため、第１開口部と第２開口部に挿入した手指等が、持手部の長手方向において弾性部材に形成された第２開口部の両端の少なくとも一端に当たりやすくなる。すなわち、該挿入した手指等は、持手部に形成された第１開口部の両端の少なくとも一端に当たりにくくなる。 In the second aspect, since the width of the second opening formed in the elastic member is shorter than the width of the first opening formed in the handle portion (central region), the first opening and the second opening are formed. The fingers or the like inserted into the grip can easily contact at least one end of both ends of the second opening formed in the elastic member in the longitudinal direction of the handle. That is, the inserted fingers or the like are less likely to hit at least one of both ends of the first opening formed in the handle.

これにより、第２の態様では、持手部を掴んだ際に手指等にかかる負荷をさらに和らげる（または緩和する）ことができる。そのため、第２の態様によれば、持手部によって手指等が締め付けられたり、手指等が痛くなるのを抑制する（持手部が掴みやすくなり、包装袋の持ち運びが容易になる）効果を高めることができる。 Accordingly, in the second aspect, it is possible to further reduce (or reduce) the load applied to the fingers and the like when the grip portion is grasped. Therefore, according to the second aspect, it is possible to prevent the fingers and the like from being tightened by the holding portion and the fingers and the like from being hurt (the holding portion can be easily grasped and the packaging bag can be easily carried). Can be increased.

また、第２の態様では、上述のように、挿入した手指等が弾性部材の第２開口部に当たりやすくなる（持手部の第１開口部に当たりにくくなる）ことで、持手部が伸びたり破断するのをさらに抑制することができる。そのため、第２の態様によれば、被包装体が収容された状態で包装袋を持ち運ぶ場合に、包装袋が破損しにくくなる効果を高めることができる。 In addition, in the second aspect, as described above, the inserted finger or the like easily hits the second opening of the elastic member (it becomes hard to hit the first opening of the handle), so that the handle extends or extends. It is possible to further suppress breakage. Therefore, according to the second aspect, it is possible to enhance the effect that the packaging bag is less likely to be damaged when the packaging bag is carried while the packaged object is accommodated.

さらに、第２の態様では、弾性部材に形成された第２開口部の幅を、持手部（中央領域）に形成された第１開口部の幅より短くしても、第２開口部に挿入された手指等に合わせて弾性部材が変形する（伸びる）ことができる。そのため、第１開口部と第２開口部に手指等を挿入して持手部を掴んだ（握った）際に、第２開口部の幅は第１開口部の幅に近くなる。これにより、第２の態様でも、安定した状態で包装袋の持手部を掴む（または握る）ことができる。 Further, in the second aspect, even if the width of the second opening formed in the elastic member is shorter than the width of the first opening formed in the handle portion (central region), the second opening portion is formed. The elastic member can be deformed (stretched) according to the inserted finger or the like. Therefore, when fingers or the like are inserted into the first opening and the second opening and the holding portion is gripped (grasped), the width of the second opening becomes close to the width of the first opening. Thereby, also in the second aspect, it is possible to grasp (or grasp) the handle portion of the packaging bag in a stable state.

なお、持手部に形成される指掛部は、一般に人の手のひらの寸法に合わせて形成されるため、手のひらよりも寸法が小さいフック等の手段に、包装袋の持手部を安定して掛けることができない傾向がある。これに対して、第２の態様では、弾性部材に形成された第２開口部の幅を持手部（中央領域）に形成された第１開口部の幅よりも短くすることで、手のひら以外の手段に対しても、包装袋の持手部を安定して掛けることが可能になる。 Since the finger hook portion formed on the handle portion is generally formed in accordance with the size of the palm of a person, the handle portion of the packaging bag can be stably attached to a means such as a hook having a size smaller than the palm. It tends to hang. On the other hand, in the second aspect, the width of the second opening formed in the elastic member is made shorter than the width of the first opening formed in the hand portion (central region), so that the width other than the palm is reduced. Even with this means, it is possible to stably hang the handle portion of the packaging bag.

In the present specification, the height of the first opening portion indicates the length (vertical width) of the first opening portion in the height direction of the handle portion, and the height of the second opening portion is the height of the handle portion. The length (vertical width) of the second opening in the depth direction is shown.

第３の態様では、弾性部材に形成された第２開口部の高さが、持手部（中央領域）に形成された第１開口部の高さと同じまたは低いため、第１開口部と第２開口部に挿入した手指等が、持手部の高さ方向において弾性部材に形成された第２開口部の上端に当たりやすくなる。すなわち、該挿入した手指等は、持手部に形成された第１開口部の上端に当たりにくくなる。 In the third aspect, since the height of the second opening formed in the elastic member is the same as or lower than the height of the first opening formed in the handle portion (central region), the first opening and the first opening The fingers or the like inserted into the two openings easily come into contact with the upper ends of the second openings formed in the elastic member in the height direction of the handle. That is, the inserted finger or the like is less likely to hit the upper end of the first opening formed in the handle portion.

これにより、第３の態様では、持手部を掴んだ際に手指等にかかる負荷をさらに和らげる（または緩和する）ことができる。そのため、第３の態様によれば、持手部によって手指等が締め付けられたり、手指等が痛くなるのを抑制する（持手部が掴みやすくなり、包装袋の持ち運びが容易になる）効果をより高めることができる。 Accordingly, in the third aspect, it is possible to further alleviate (or alleviate) the load applied to the fingers and the like when gripping the holding portion. Therefore, according to the third aspect, it is possible to prevent the fingers and the like from being tightened by the holding part and to prevent the fingers and the like from being hurt (the holding part is easy to grasp and the packaging bag is easy to carry). It can be increased.

また、第３の態様では、上述のように、挿入した手指等が弾性部材の第２開口部の上端に当たりやすくなる（持手部の第１開口部の上端に当たりにくくなる）ことで、持手部が伸びたり破断するのをさらに抑制することができる。そのため、第３の態様によれば、被包装体が収容された状態で包装袋を持ち運ぶ場合に、包装袋が破損しにくくなる効果をより高めることができる。 In addition, in the third aspect, as described above, the inserted finger or the like easily hits the upper end of the second opening portion of the elastic member (it becomes hard to hit the upper end of the first opening portion of the handle portion). It is possible to further prevent the portion from extending or breaking. Therefore, according to the third aspect, it is possible to further enhance the effect that the packaging bag is less likely to be damaged when the packaging bag is carried while the packaged object is accommodated.

さらに、第３の態様では、弾性部材に形成された第２開口部の高さを、持手部（中央領域）に形成された第１開口部の高さより低くても、第２開口部に挿入された手指等に合わせて弾性部材が変形する（伸びる）ことができる。そのため、第１開口部と第２開口部に手指等を挿入して持手部を掴んだ（握った）際に、第２開口部の高さは第１開口部の高さに近くなる。これにより、第３の態様でも、安定した状態で包装袋の持手部を掴む（または握る）ことができる。 Furthermore, in the third aspect, even if the height of the second opening formed in the elastic member is lower than the height of the first opening formed in the handle portion (central region), the second opening is formed in the second opening. The elastic member can be deformed (stretched) according to the inserted finger or the like. Therefore, when a finger or the like is inserted into the first opening and the second opening and the holding portion is gripped (gripped), the height of the second opening becomes close to the height of the first opening. Thereby, also in the third aspect, the handle portion of the packaging bag can be grasped (or grasped) in a stable state.

また、第３の態様では、弾性部材に形成された第２開口部の高さを持手部（中央領域）に形成された第１開口部の高さ以下にすることで、手のひら以外の手段に対しても、包装袋の持手部を安定して掛けることが可能になる。 Further, in the third aspect, the height of the second opening formed in the elastic member is set to be equal to or lower than the height of the first opening formed in the hand portion (central region), so that means other than the palm is provided.

Since the central area of the handle portion is surrounded by such a seal portion, the first opening portion formed in the handle portion (central area) and the second opening portion formed in the elastic member are also surrounded by the seal portion. It becomes a thing. Accordingly, in the seventh aspect, the central portion of the handle portion (finger hanging portion formed of the first opening portion and the second opening portion) can be reinforced by the seal portion, and the first opening portion and/or Alternatively, it is possible to prevent the handle portion from breaking from the second opening.

また、第７の態様では、弾性部材がシール部により持手部に接着されていることで、弾性部材を持手部の中央領域に対して確実に形成することができる。さらに、弾性部材の第２開口部を持手部（中央領域）の第１開口部に確実に重ねることができる。 Further, in the seventh aspect, since the elastic member is bonded to the handle portion by the seal portion, the elastic member can be reliably formed in the central region of the handle portion. Further, the second opening of the elastic member can be reliably overlapped with the first opening of the hand portion (central region).

本発明に係る第８の態様は、前記持手部に形成され、前記弾性部材を覆う可撓性部材を有し、前記可撓性部材の厚み方向に貫通し、前記第２開口部に重なる第３開口部が形成されている、包装袋である。本明細書において、可撓性部材とは、柔軟性があり、折り曲げることが可能な部材を示す。可撓性部材の形態は、特に限定されず、シート、フィルム、フィルムまたはシートを複数枚積層したもの等が挙げられる。 An eighth aspect according to the present invention has a flexible member that is formed on the handle portion and covers the elastic member, penetrates in the thickness direction of the flexible member, and overlaps the second opening portion. It is a packaging bag in which the 3rd opening is formed. In this specification, the flexible member refers to a member that is flexible and can be bent. The form of the flexible member is not particularly limited, and examples thereof include a sheet, a film, and a laminate of a plurality of films or sheets.

可撓性部材の材質は、特に限定されず、ポリエチレン（ＰＥ）、ポリプロピレン（ＰＰ）、ポリエチレンテレフタレート（ＰＥＴ）、およびＰＥ−エチレンビニルアルコール共重合体（ＥＶＯＨ）−ＰＥの積層体（ＰＥ／ＥＶＯＨ／ＰＥ）、ポリ塩化ビニリデン（ＰＶＤＣ）、等が挙げられる。また、可撓性部材の材質は、上述の弾性部材（熱可塑性エラストマー等）と同じ材質を用いても良い。 The material of the flexible member is not particularly limited, and a laminated body (PE/EVOH) of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and PE-ethylene vinyl alcohol copolymer (EVOH)-PE. /PE), polyvinylidene chloride (PVDC), and the like. The material of the flexible member may be the same as that of the elastic member (thermoplastic elastomer or the like) described above.

また、第３開口部が第２開口部に重なるとは、第３開口部の全部が第２開口部の全部と重なる場合、第３開口部の全部が第２開口部の一部と重なる場合、第３開口部の一部が第２開口部の全部と重なる場合、第３開口部の一部が第２開口部の一部と重なる場合のいずれでもよいことを示す。なお、第３開口部の形態は、限定されず、第１開口部、第２開口部と同様に、スリット、貫通孔等で形成することができる。また、第３開口部を構成するスリット、貫通孔等は、持手部に形成されたミシン目を破ることで形成してもよい。 Further, the term “the third opening overlaps with the second opening” means that all of the third opening overlaps with all of the second opening, and all of the third opening overlaps with part of the second opening. , That part of the third opening overlaps all of the second opening, and part of the third opening overlaps part of the second opening. The form of the third opening is not limited, and the third opening can be formed by a slit, a through hole, or the like, like the first opening and the second opening. Further, the slits, the through holes, and the like that form the third opening may be formed by breaking the perforations formed in the handle portion.

第８の態様では、弾性部材を蓋う可撓性部材が持手部に形成され、弾性部材に形成された第２開口部に対して可撓性部材に形成された第３開口部が重なることで、第３開口部にも手指等を挿入することができ、該手指等で持手部を掴む（または握る）ことができる。そのため、第３開口部は、第１開口部および第２開口部とともに持手部の指掛部を構成することができる。 In the eighth aspect, a flexible member that covers the elastic member is formed in the handle portion, and the third opening formed in the flexible member overlaps the second opening formed in the elastic member. Thus, the fingers and the like can be inserted into the third opening, and the holding portion can be gripped (or grasped) by the fingers and the like. Therefore, the third opening can form a finger hook of the handle with the first opening and the second opening.

また、第８の態様では、弾性部材を蓋う可撓性部材が持手部に形成されているため、可撓性部材が持手部に構成される指掛部を補強することができる。また、弾性部材は、可撓性部材と持手部の中央領域との間に挟み込まれているため、持手部を掴んだ（または握った）ときに弾性部材の一部のみが手指等に当たる。そのため、第８の態様では、可撓性部材によって弾性部材を保護することができる。 Further, in the eighth aspect, since the flexible member that covers the elastic member is formed in the handle portion, it is possible to reinforce the finger hook portion in which the flexible member is included in the handle portion. Further, since the elastic member is sandwiched between the flexible member and the central region of the handle portion, only a part of the elastic member hits a finger or the like when gripping (or grasping) the handle portion. .. Therefore, in the eighth aspect, the elastic member can be protected by the flexible member.

本発明に係る第９の態様は、前記第３開口部の幅が、前記第１開口部の幅と同じである、包装袋である。本明細書において、第３開口部の幅は、持手部の長手方向における第３開口部の長さ（横幅）を示す。また、第３開口部の幅が第１開口部の幅と同じであるとは、第３開口部の幅と第１開口部の幅とが、略同一であればよく、全くの同一である必要はないことを示す。なお、第３開口部が第１開口部に重なる部分は、持手部の指掛部を構成する観点から、第１開口部の幅の約８０％以上を占める部分となることが好ましい。 A ninth aspect according to the present invention is a packaging bag in which the width of the third opening is the same as the width of the first opening. In the present specification, the width of the third opening indicates the length (width) of the third opening in the longitudinal direction of the handle. The width of the third opening being the same as the width of the first opening means that the width of the third opening and the width of the first opening are substantially the same, and are exactly the same. Indicates that there is no need. The portion where the third opening overlaps the first opening is preferably a portion that occupies about 80% or more of the width of the first opening from the viewpoint of forming the finger hook of the handle.

第９の態様では、可撓性部材に形成された第３開口部の幅が持手部（中央領域）に形成された第１開口部の幅と同じであるため、該第３開口部の幅は、弾性部材に形成された第２開口部の幅より長いものとなる。これにより、第９の態様では、持手部に可撓性部材を形成した場合でも、第３開口部への手指等の挿入が妨げられるのを防ぐことができる。 In the ninth aspect, since the width of the third opening formed in the flexible member is the same as the width of the first opening formed in the handle portion (central region), the third opening of the third opening The width is longer than the width of the second opening formed in the elastic member. Accordingly, in the ninth aspect, even when the flexible member is formed on the handle portion, it is possible to prevent the insertion of the finger or the like from being inserted into the third opening.

また、第９の態様では、弾性部材に形成された第２開口部の幅は、持手部（中央領域）に形成された第１開口部の幅および可撓性部材に形成された第３開口部の幅のいずれに対しても短いものとなる。そのため、第１開口部、第２開口部、及び第３開口部に挿入した手指等が、弾性部材に形成された第２開口部に当たりやすくなる。すなわち、該挿入した手指等は、持手部（中央領域）に形成された第１開口部および可撓性部材に形成された第３開口部のいずれにも当たりにくくなる。 Further, in the ninth aspect, the width of the second opening formed in the elastic member is the width of the first opening formed in the handle portion (central region) and the width of the third opening formed in the flexible member. It will be short for any of the widths of the openings. Therefore, fingers and the like inserted into the first opening, the second opening, and the third opening are likely to hit the second opening formed in the elastic member. That is, the inserted finger or the like is unlikely to hit either the first opening formed in the handle portion (central region) or the third opening formed in the flexible member.

これにより、第９の態様では、持手部に可撓性部材を形成した場合でも、持手部を掴んだ際に手指等にかかる負荷をさらに和らげる（または緩和する）ことができる。そのため、第９の態様によれば、持手部に形成された可撓性部材によって手指等が締め付けられたり、手指等が痛くなるのを抑制する（持手部が掴みやすくなり、包装袋の持ち運びが容易になる）効果を高めることができる。 Accordingly, in the ninth aspect, even when the flexible member is formed on the handle portion, it is possible to further reduce (or reduce) the load applied to the fingers and the like when the handle portion is gripped. Therefore, according to the ninth aspect, it is possible to prevent the fingers or the like from being tightened or the fingers or the like from being hurt by the flexible member formed in the handle portion (the handle portion can be easily grasped, (Easy to carry) It can improve the effect.

本発明に係る第１０の態様は、前記中央領域は、前記持手部に形成されたシール部に囲まれており、前記可撓性部材は、前記シール部により前記持手部に接着されている、包装袋である。持手部の中央領域がこのようなシール部で囲まれることにより、持手部（中央領域）に形成された第１開口部および弾性部材に形成された第２開口部とともに、可撓性部材に形成された第３開口部もシール部に囲まれたものとなる。これにより、第１０の態様では、シール部によって、持手部の中央領域（第１開口部および第２開口部とともに第３開口部で構成される指掛部）持手部の指掛部を補強することができ、第３開口部を起点に持手部が破断するのを抑制することができる。 In a tenth aspect according to the present invention, the central region is surrounded by a seal portion formed on the handle portion, and the flexible member is bonded to the handle portion by the seal portion. It is a packaging bag. By surrounding the central region of the handle part with such a seal part, the flexible member is provided with the first opening formed in the handle part (central region) and the second opening formed in the elastic member. The third opening formed in is also surrounded by the seal portion. With this, in the tenth aspect, the central portion of the handle portion (the finger hook portion configured by the third opening portion together with the first opening portion and the second opening portion) causes the seal portion to move the finger hook portion of the handle portion. It is possible to reinforce, and it is possible to prevent the handle portion from breaking from the third opening.

また、第１０の態様では、可撓性部材がシール部により持手部に接着されていることで、可撓性部材を持手部に対して確実に形成することができる。さらに、可撓性部材の第３開口部を、弾性部材の第２開口部に確実に重ねることができる。 Further, in the tenth aspect, since the flexible member is bonded to the handle portion by the seal portion, the flexible member can be reliably formed on the handle portion. Furthermore, the third opening of the flexible member can be reliably overlapped with the second opening of the elastic member.

図５〜図７は、本実施形態に係る包装袋１００の使用態様を示す図である。ここでは、本実施形態による本発明の効果について説明する。 5 to 7 are views showing a usage mode of the packaging bag 100 according to the present embodiment. Here, the effects of the present invention according to the present embodiment will be described.

本実施形態では、上述のように持手部２０の中央領域２５に弾性部材４０が形成され、該中央領域２５に形成された第１開口部３１に対して弾性部材４０に形成された第２開口部４１が重なっている（図１〜図４参照）。このような構成により、第１開口部３１および第２開口部４１に手指または手のひら（以下、手指等という）Ｐを通すことができる（図５、図６）。そして、該挿入した手指等Ｐで持手部２０を掴む（または握る）ことができる（図７参照）。このように、本実施形態では、第１開口部３１および第２開口部４１が、持手部２０の指掛部３０を構成することができる。 In the present embodiment, the elastic member 40 is formed in the central region 25 of the handle portion 20 as described above, and the second member formed in the elastic member 40 with respect to the first opening 31 formed in the central region 25. The openings 41 overlap (see FIGS. 1 to 4 ). With such a configuration, a finger or a palm (hereinafter referred to as a finger) P can be passed through the first opening 31 and the second opening 41 (FIGS. 5 and 6). Then, the holding hand 20 can be grasped (or grasped) by the inserted fingers or the like P (see FIG. 7). As described above, in the present embodiment, the first opening 31 and the second opening 41 can form the finger hook 30 of the handle 20.

また、本実施形態では、第１開口部３１および第２開口部４１（指掛部３０）に該手指等Ｐを挿入し持手部２０を掴む（または握る）と、第２開口部４１が形成された弾性部材４０の一部（第２開口部４１の上方部分４２）を掴むことができる。そして、持手部２０に形成された弾性部材４０は、持手部２０を掴んだときに生じた外力により変形し、手指等Ｐにかかる圧力を吸収することができる。（図７参照） In addition, in the present embodiment, when the fingers P etc. are inserted into the first opening 31 and the second opening 41 (finger hooking portion 30) and the holding portion 20 is gripped (or gripped), the second opening 41 is opened. It is possible to grasp a part of the formed elastic member 40 (the upper portion 42 of the second opening 41). Then, the elastic member 40 formed on the holding portion 20 is deformed by an external force generated when the holding portion 20 is gripped, and can absorb the pressure applied to the fingers P or the like. (See Figure 7)

また、本実施形態では、弾性部材４０が持手部２０を掴んだ手指等Ｐの状態に合わせて形状が変化する（または弾性部材４０が伸び縮みする）。具体的には、弾性部材４０は、持手部２０を掴んだ（または握った）ときに手指等Ｐに馴染んだ形で当たる（フィットする）。そのため、持手部２０の中央領域２５に弾性部材４０が形成された持手部２０は、安定した状態で掴む（または握る）ことができる。 Further, in the present embodiment, the shape of the elastic member 40 changes (or the elastic member 40 expands and contracts) according to the state of the finger or the like P that grips the holding portion 20. Specifically, the elastic member 40 hits (fits) in a form familiar to the finger P when the grip 20 is (or is) gripped. Therefore, the grip 20 having the elastic member 40 formed in the central region 25 of the grip 20 can be gripped (or gripped) in a stable state.

また、本実施形態では、弾性部材４０は保形性を有するため、持手部２０を掴んだときに持手部２０に形成された弾性部材４０の一部（上方部分４２）が、手指等Ｐに対して面状に当たりやすくなる。すなわち、持手部２０に設けられた弾性部材４０の一部分は、手指等Ｐに対して線状に当たりにくくなる。 Further, in the present embodiment, since the elastic member 40 has the shape-retaining property, a part (upper part 42) of the elastic member 40 formed on the holding portion 20 when the holding portion 20 is gripped is a finger or the like. It becomes easy to hit P in a planar manner. That is, a part of the elastic member 40 provided on the handle portion 20 is less likely to linearly contact the finger P or the like.

このような構成により、本実施形態では、持手部２０を掴んだ際に手指等Ｐにかかる負荷を和らげる（または緩和する）ことができる。そのため、持手部２０によって手指等Ｐが締め付けられたり、手指等Ｐが痛くなるのを抑制することができる。そのため、本実施形態によれば、持手部２０が掴みやすく（または握りやすく）なり、包装袋１００の持ち運びが容易になる。 With this configuration, in the present embodiment, it is possible to reduce (or reduce) the load applied to the fingers P and the like when gripping the holding portion 20. Therefore, it is possible to prevent the fingers P and the like from being tightened by the holding portion 20 and the fingers P and the like from being hurt. Therefore, according to the present embodiment, the handle portion 20 is easily gripped (or easily gripped), and the packaging bag 100 is easily carried.

また、本実施形態では、第１開口部３１を覆う弾性部材４０が持手部２０の中央領域２５に形成されているため、弾性部材４０が持手部２０の中央領域２５（持手部２０の指掛部３０が構成される部分）を補強することができる。また、このような弾性部材４０により、上述のように手指等Ｐにかかる圧力が吸収され、また、持手部２０を安定した状態で掴める（または握れる）ことで、持手部２０が伸びたり、破断するのを抑制することができる。そのため、本実施形態によれば、被包装体Ｔが収容された状態で包装袋１００を持ち運ぶ場合に、包装袋１００が破損しにくくなる。 In addition, in the present embodiment, since the elastic member 40 that covers the first opening 31 is formed in the central region 25 of the handle portion 20, the elastic member 40 is disposed in the central region 25 of the handle portion 20 (the handle portion 20. Can be reinforced. Further, the elastic member 40 absorbs the pressure applied to the fingers P as described above, and the grip 20 can be grasped (or grasped) in a stable state, whereby the grip 20 can be stretched. It is possible to suppress the breakage. Therefore, according to the present embodiment, the packaging bag 100 is less likely to be damaged when the packaging bag 100 is carried while the packaged object T is accommodated.

第１実施形態では、上述のように、弾性部材４０に形成された第２開口部４１の幅Ｌ２が、持手部２０（中央領域２５）に形成された第１開口部３１の幅Ｌ１より短いため、第１開口部３１と第２開口部４１に挿入した手指等Ｐが、持手部２０の長手方向（Ｘ方向）において弾性部材４０に形成された第２開口部４１の両端４１Ａ、４１Ｂの少なくとも一端に当たりやすくなる。すなわち、該挿入した手指等Ｐは、持手部２０に形成された第１開口部３１の両端３１Ａ、３１Ｂの少なくとも一端に当たりにくくなる（図３、図７参照）。 In the first embodiment, as described above, the width L2 of the second opening portion 41 formed in the elastic member 40 is larger than the width L1 of the first opening portion 31 formed in the handle portion 20 (central region 25). Since the length is short, the fingers or the like P inserted in the first opening 31 and the second opening 41 have both ends 41A of the second opening 41 formed in the elastic member 40 in the longitudinal direction (X direction) of the holding portion 20, It becomes easy to hit at least one end of 41B. That is, it is difficult for the inserted finger or the like P to hit at least one end of both ends 31A and 31B of the first opening 31 formed in the holding portion 20 (see FIGS. 3 and 7).

これにより、本実施形態では、持手部２０を掴んだ際に手指等Ｐにかかる負荷をさらに和らげる（または緩和する）ことができる。そのため、本実施形態では、持手部２０によって手指等Ｐが締め付けられたり、手指等Ｐが痛くなるのを抑制する（持手部２０が掴みやすくなり、包装袋１００の持ち運びが容易になる）効果を高めることができる。 As a result, in the present embodiment, it is possible to further alleviate (or alleviate) the load applied to the fingers P and the like when gripping the holding portion 20. Therefore, in the present embodiment, it is possible to prevent the fingers 20 and the like P from being tightened by the holding portion 20 and the fingers and the like P from being hurt (the holding portion 20 can be easily grasped and the packaging bag 100 can be easily carried). The effect can be enhanced.

また、本実施形態では、上述のように、挿入した手指等Ｐが弾性部材４０の第２開口部４１に当たりやすくなる（持手部２０の第１開口部３１に当たりにくくなる）ことで、持手部２０が伸びたり破断するのをさらに抑制することができる。そのため、本実施形態によれば、被包装体Ｔが収容された状態で包装袋１００を持ち運ぶ場合に、包装袋１００が破損しにくくなる効果を高めることができる。 In addition, in the present embodiment, as described above, the inserted finger P or the like easily hits the second opening 41 of the elastic member 40 (it becomes hard to hit the first opening 31 of the holding part 20), and thus the holding hand. It is possible to further prevent the portion 20 from extending or breaking. Therefore, according to the present embodiment, when carrying the packaging bag 100 in a state where the body T to be packaged is accommodated, the effect that the packaging bag 100 is less likely to be damaged can be enhanced.

さらに、本実施形態では、上述のように弾性部材４０に形成された第２開口部４１の幅Ｌ２を、持手部２０（中央領域２５）に形成された第１開口部３１の幅Ｌ１より短くてしても、第２開口部４１に挿入された手指等Ｐに合わせて弾性部材４０が変形する（伸びる）ことができる。そのため、第１開口部３１と第２開口部４１に手指等Ｐを挿入して持手部２０を掴んだ（握った）際に、第２開口部４１の幅Ｌ２は第１開口部３１の幅Ｌ１に近くなる。これにより、本実施形態では、安定した状態で包装袋１００の持手部２０を掴む（または握る）ことができる。 Further, in the present embodiment, the width L2 of the second opening 41 formed in the elastic member 40 as described above is larger than the width L1 of the first opening 31 formed in the handle portion 20 (central region 25). Even if the length is short, the elastic member 40 can be deformed (stretched) according to the finger P or the like inserted into the second opening 41. Therefore, when the fingers P etc. are inserted into the first opening portion 31 and the second opening portion 41 and the holding portion 20 is gripped (grasped), the width L2 of the second opening portion 41 is equal to that of the first opening portion 31. It is close to the width L1. Thereby, in the present embodiment, the handle portion 20 of the packaging bag 100 can be grasped (or grasped) in a stable state.

なお、持手部に形成される指掛部は、一般に人の手のひらの寸法に合わせて形成されるため、手のひらよりも寸法が小さいフック等の手段に、包装袋の持手部を安定して掛けることができない傾向がある。これに対して、本実施形態では、弾性部材４０に形成された第２開口部４１の幅Ｌ２を持手部２０（中央領域２５）に形成された第１開口部３１の幅Ｌ１よりも短くすることで、手のひら以外の手段に対しても、包装袋１００の持手部２０を安定して掛けることが可能になる。 Since the finger hook portion formed on the handle portion is generally formed in accordance with the size of the palm of a person, the handle portion of the packaging bag can be stably attached to a means such as a hook having a size smaller than the palm. It tends to hang. On the other hand, in the present embodiment, the width L2 of the second opening 41 formed in the elastic member 40 is shorter than the width L1 of the first opening 31 formed in the hand portion 20 (central region 25). By doing so, the handle 20 of the packaging bag 100 can be stably hung on a means other than the palm.

第１実施形態では、上述のように、弾性部材４０に形成された第２開口部４１の高さＨ２が、持手部２０（中央領域２５）に形成された第１開口部３１の高さＨ１以下である（本実施形態では、高さＨ１より低い）ため、第１開口部３１と第２開口部４１に挿入した手指等Ｐが、持手部２０の高さ方向（Ｙ方向）において弾性部材４０に形成された第２開口部４１の上端４１Ｃに当たりやすくなる。すなわち、該挿入した手指等Ｐは、持手部２０に形成された第１開口部３１の上端３１Ｃに当たりにくくなる（図３、図７参照）。 In the first embodiment, as described above, the height H2 of the second opening portion 41 formed in the elastic member 40 is the height of the first opening portion 31 formed in the handle portion 20 (central region 25). Since it is equal to or less than H1 (lower than the height H1 in the present embodiment), the fingers P or the like inserted into the first opening 31 and the second opening 41 in the height direction (Y direction) of the handle portion 20. The upper end 41C of the second opening 41 formed in the elastic member 40 is easily hit. That is, the inserted finger P or the like is less likely to hit the upper end 31C of the first opening 31 formed in the holding portion 20 (see FIGS. 3 and 7).

これにより、本実施形態では、持手部２０を掴んだ際に手指等Ｐにかかる負荷をさらに和らげる（または緩和する）ことができる。そのため、本実施形態によれば、持手部２０によって手指等Ｐが締め付けられたり、手指等Ｐが痛くなるのを抑制する（持手部２０が掴みやすくなり、包装袋１００の持ち運びが容易になる）効果をより高めることができる。 As a result, in the present embodiment, it is possible to further alleviate (or alleviate) the load applied to the fingers P and the like when gripping the holding portion 20. Therefore, according to the present embodiment, it is possible to prevent the fingers P and the like from being tightened by the holding portion 20 and the fingers P and the like from being hurt (the holding portion 20 can be easily grasped and the packaging bag 100 can be easily carried. Can be more effective.

また、本実施形態では、上述のように、挿入した手指等Ｐが弾性部材４０の第２開口部４１の上端４１Ｃに当たりやすくなる（持手部２０の第１開口部３１の上端３１Ｃに当たりにくくなる）ことで、持手部２０が伸びたり破断するのをさらに抑制することができる。そのため、本実施形態によれば、被包装体Ｔが収容された状態で包装袋１００を持ち運ぶ場合に、包装袋１００が破損しにくくなる効果をより高めることができる。 Further, in the present embodiment, as described above, the inserted finger or the like P easily hits the upper end 41C of the second opening 41 of the elastic member 40 (it becomes hard to hit the upper end 31C of the first opening 31 of the handle 20). Therefore, it is possible to further prevent the handle portion 20 from extending or breaking. Therefore, according to the present embodiment, when carrying the packaging bag 100 in a state where the packaged object T is housed, the effect of making the packaging bag 100 less likely to be damaged can be further enhanced.

さらに、本実施形態では、弾性部材４０に形成された第２開口部４１の高さＨ２を、持手部２０（中央領域２５）に形成された第１開口部３１の高さＨ１より低くても、第２開口部４１に挿入された手指等Ｐに合わせて弾性部材４０が変形する（伸びる）ことができる。そのため、第１開口部３１と第２開口部４１に手指等を挿入して持手部を掴んだ（握った）際に、第２開口部４１の高さＨ２は第１開口部３１の高さＨ１に近くなる。これにより、本実施形態でも、安定した状態で持手部を掴む（または握る）ことができる。 Further, in the present embodiment, the height H2 of the second opening 41 formed in the elastic member 40 is set lower than the height H1 of the first opening 31 formed in the handle portion 20 (central region 25). Also, the elastic member 40 can be deformed (stretched) according to the finger P or the like inserted in the second opening 41. Therefore, when a finger or the like is inserted into the first opening portion 31 and the second opening portion 41 to grasp (grip) the holding portion, the height H2 of the second opening portion 41 is equal to the height of the first opening portion 31. It will be close to H1. As a result, also in the present embodiment, it is possible to grasp (or grasp) the handle portion in a stable state.

また、本実施形態では、弾性部材４０に形成された第２開口部４１の高さＨ２を持手部２０（中央領域２５）に形成された第１開口部３１の高さＨ１以下にする（本実施形態では、高さＨ１より低くする）ことで、手のひら以外の手段に対しても、包装袋１００の持手部２０を安定して掛けることが可能になる。 Further, in the present embodiment, the height H2 of the second opening 41 formed in the elastic member 40 is set to be equal to or lower than the height H1 of the first opening 31 formed in the hand portion 20 (central region 25) ( In the present embodiment, the height H1 is lower than the height H1), so that the handle portion 20 of the packaging bag 100 can be stably hung on means other than the palm.

第１実施形態では、伸長率が上述の範囲の弾性部材４０を用いることにより、持手部２０を掴んだ（または握った）ときの手指等Ｐにかかる圧力を弾性部材４０が吸収する効果を高めることができる。また、持手部２０を掴んだ（または握った）手指等Ｐの状態に合わせて、弾性部材４０の形状が変化する（または弾性部材４０が伸び縮みする）効果を高めることができる。 In the first embodiment, by using the elastic member 40 having the extension rate in the above range, the effect that the elastic member 40 absorbs the pressure applied to the finger P when the grip 20 is (or is) gripped is obtained. Can be increased. In addition, the effect that the shape of the elastic member 40 changes (or the elastic member 40 expands and contracts) can be enhanced in accordance with the state of the finger or the like P that holds (or holds) the holding portion 20.

第１実施形態では、ヤング率が上述の範囲の弾性部材４０を用いることにより、持手部２０を掴んだときの手指等Ｐにかかる圧力を弾性部材４０が吸収する効果をさらに高めることができる。また、弾性部材４０が持手部２０を掴んだ（または握った）手指等Ｐの状態に合わせて形状が変化する（または弾性部材４０が伸び縮みする）効果をさらに高めることができる。 In the first embodiment, by using the elastic member 40 having the Young's modulus in the above range, the effect of the elastic member 40 absorbing the pressure exerted on the finger P or the like when the grip 20 is gripped can be further enhanced. .. Further, it is possible to further enhance the effect that the elastic member 40 changes its shape (or the elastic member 40 expands and contracts) according to the state of the finger P or the like that grips (or grips) the holding portion 20.

第１実施形態では、ＪＩＳ Ｋ ６２５３（２０１２）に準拠する硬度がこのような範囲の弾性部材４０を用いることにより、持手部２０を掴んだ（または握った）ときに、弾性部材４０と手指等Ｐとの間にグリップ力が生じ、より安定した状態で持手部２０を掴む（または握る）ことができる。また、このようなグリップ力により、持手部２０を掴んだ（または握った）ときに、弾性部材４０が手指等Ｐに馴染んだ形で当たる（フィットする）効果を高めることができる。 In the first embodiment, by using the elastic member 40 having a hardness according to JIS K 6253 (2012) in such a range, the elastic member 40 and the fingers are grasped when the grip 20 is (or is) gripped. Grip force is generated between the handle P and the like P, and the grip 20 can be gripped (or gripped) in a more stable state. Further, such gripping force can enhance the effect of the elastic member 40 hitting (fitting) in a form familiar to the finger P when the grip 20 is gripped (or gripped).

第１実施形態では、持手部２０の中央領域２５がこのようなシール部５０で囲まれることにより、持手部２０（中央領域２５）に形成された第１開口部３１および弾性部材４０に形成された第２開口部４１もシール部５０に囲まれたものとなる。これにより、本実施形態では、シール部５０によって、持手部２０の中央領域２５（第１開口部３１および第２開口部４１で構成される指掛部３０）を補強することができ、第１開口部３１および／または第２開口部４１を起点に持手部２０が破断するのを抑制することができる。 In the first embodiment, the central region 25 of the handle portion 20 is surrounded by the seal portion 50, so that the first opening portion 31 and the elastic member 40 formed in the handle portion 20 (central region 25) are provided. The formed second opening 41 is also surrounded by the seal portion 50. As a result, in the present embodiment, the central portion 25 (the finger hook portion 30 configured by the first opening portion 31 and the second opening portion 41) of the handle portion 20 can be reinforced by the seal portion 50. It is possible to prevent the handle portion 20 from breaking from the first opening portion 31 and/or the second opening portion 41 as a starting point.

また、本実施形態では、弾性部材４０がシール部５０により持手部２０に接着されていることで、弾性部材４０を持手部２０の中央領域２５に対して確実に形成することができる。さらに、弾性部材４０の第２開口部４１を持手部２０（中央領域２５）の第１開口部３１に確実に重ねることができる。 Further, in the present embodiment, since the elastic member 40 is bonded to the handle portion 20 by the seal portion 50, the elastic member 40 can be reliably formed in the central region 25 of the handle portion 20. Furthermore, the second opening 41 of the elastic member 40 can be reliably overlapped with the first opening 31 of the hand portion 20 (central region 25).

図８は、本実施形態（第２実施形態）に係る包装袋１００の持手部２０を示す。図９は、図８のＢ−Ｂ線断面図である。なお、図８、図９において、第１実施形態と共通する部分は、同一の符号を付して説明を省略する。 FIG. 8 shows the handle portion 20 of the packaging bag 100 according to the present embodiment (second embodiment). FIG. 9 is a sectional view taken along line BB of FIG. 8 and 9, the same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

第２実施形態に係る包装袋１００では、持手部２０に弾性部材４０を覆う可撓性部材６０が形成されている。可撓性部材６０は、柔軟性があり、折り曲げることが可能な部材である。可撓性部材６０の形態は、特に限定されず、シート、フィルム、フィルムまたはシートを複数枚積層したもの等が挙げられる。 In the packaging bag 100 according to the second embodiment, a flexible member 60 that covers the elastic member 40 is formed on the handle portion 20. The flexible member 60 is a member that is flexible and can be bent. The form of the flexible member 60 is not particularly limited, and examples thereof include a sheet, a film, and a laminate of a plurality of films or sheets.

可撓性部材６０の材質は、特に限定されず、ポリエチレン（ＰＥ）、ポリプロピレン（ＰＰ）、ポリエチレンテレフタレート（ＰＥＴ）、およびＰＥ−エチレンビニルアルコール共重合体（ＥＶＯＨ）−ＰＥの積層体（ＰＥ／ＥＶＯＨ／ＰＥ）、ポリ塩化ビニリデン（ＰＶＤＣ）等が挙げられる。また、可撓性部材６０の材質は、上述の弾性部材４０と同じ材質（熱可塑性エラストマー等）を用いても良い。第２実施形態では、可撓性部材６０として、ポリエチレン（ＰＥ）のシートが用いられている。 The material of the flexible member 60 is not particularly limited, and is a laminate (PE/PE) of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and PE-ethylene vinyl alcohol copolymer (EVOH)-PE. EVOH/PE), polyvinylidene chloride (PVDC) and the like. The material of the flexible member 60 may be the same as that of the elastic member 40 described above (such as thermoplastic elastomer). In the second embodiment, a polyethylene (PE) sheet is used as the flexible member 60.

また、可撓性部材６０の厚み寸法は、特に限定されず、例えば、２０μｍ以上にすることができ、好ましくは３０μｍ以上１５０μｍ以下、より好ましくは５０μｍ以下１３０μｍ以下である。可撓性部材６０の厚み寸法をこのような範囲にすることにより、持手部２０が伸びたり、破断するのを防ぐことができる。また、可撓性部材は、上述の熱溶着等により、シール部５０の形成時に、持手部２０に接着することができる。 The thickness dimension of the flexible member 60 is not particularly limited and may be, for example, 20 μm or more, preferably 30 μm or more and 150 μm or less, and more preferably 50 μm or less and 130 μm or less. By setting the thickness dimension of the flexible member 60 in such a range, it is possible to prevent the handle portion 20 from extending or breaking. Further, the flexible member can be adhered to the handle portion 20 when the seal portion 50 is formed by the above-described heat welding or the like.

可撓性部材６０は、さらに第３開口部６１を有する。第３開口部６１は、可撓性部材６０を厚み方向（Ｚ方向）に貫通するように形成されている。第２実施形態では、第３開口部６１は、持手部２０の長手方向（Ｘ方向）に延びる直線状のスリットで形成されている。なお、可撓性部材６０に形成された第３開口部６１は、本発明に係る包装袋において可撓性部材の厚み方向（Ｚ方向）に貫通する第３開口部の一例である。 The flexible member 60 further has a third opening 61. The third opening 61 is formed so as to penetrate the flexible member 60 in the thickness direction (Z direction). In the second embodiment, the third opening 61 is formed by a linear slit extending in the longitudinal direction (X direction) of the handle 20. The third opening 61 formed in the flexible member 60 is an example of a third opening that penetrates in the thickness direction (Z direction) of the flexible member in the packaging bag according to the present invention.

第３開口部６１の形態は、スリットに限定されず、例えば、持手部２０の長手方向（Ｘ方向）が長軸となる楕円状の貫通孔等で形成することができる。また、第３開口部６１を構成するスリット、貫通孔等は、第１開口部３１と同様に、持手部２０に形成されたミシン目を破ることで形成してもよい。 The form of the third opening 61 is not limited to the slit, and can be formed by, for example, an elliptical through hole having the major axis in the longitudinal direction (X direction) of the handle portion 20. In addition, the slits, the through holes, and the like that form the third opening 61 may be formed by breaking the perforations formed in the handle 20 as in the case of the first opening 31.

第３開口部６１の形状は、図８に示すような直線状に限定されず、曲線状、波線状、円形、楕円形、四角形等の形状やこれらに類似する形状等のいずれであってもよい。また、第２実施形態では、第３開口部６１が１つのスリットで形成されているが（図８参照）、スリットの個数は限定されない。したがって、第３開口部６１は、２つ以上のスリットまたは貫通孔等で形成してもよく、例えば、持手部２０の長手方向（Ｘ方向）に所定の間隔をあけて配置された２つのスリットで形成することができる。 The shape of the third opening 61 is not limited to the linear shape as shown in FIG. 8, and may be a curved shape, a wavy shape, a circular shape, an elliptical shape, a quadrangular shape or the like, or a shape similar thereto. Good. Further, in the second embodiment, the third opening 61 is formed by one slit (see FIG. 8), but the number of slits is not limited. Therefore, the third opening 61 may be formed by two or more slits or through holes or the like, and for example, two third openings 61 arranged at a predetermined interval in the longitudinal direction (X direction) of the handle portion 20. It can be formed with a slit.

第３開口部６１は、弾性部材４０に形成された第２開口部４１に重なるように、可撓性部材６０に形成されている。第２実施形態では、第３開口部６１の一部が第２開口部４１の全部と重なっている（図８、図９参照）。なお、第３開口部６１が第２開口部４１に重なる態様は、第２実施形態に限定されず、第３開口部６１の全部が第２開口部４１の全部と重なる場合、第３開口部６１の全部が第２開口部４１の一部と重なる場合、または第３開口部６１の一部が第２開口部４１の一部と重なる場合でもよい。 The third opening 61 is formed in the flexible member 60 so as to overlap the second opening 41 formed in the elastic member 40. In the second embodiment, a part of the third opening 61 overlaps the entire second opening 41 (see FIGS. 8 and 9). The aspect in which the third opening 61 overlaps the second opening 41 is not limited to the second embodiment, and when the third opening 61 entirely overlaps the second opening 41, the third opening 61 overlaps. The whole 61 may overlap with a part of the second opening 41, or the part of the third opening 61 may overlap with a part of the second opening 41.

また、第２実施形態の包装袋１００では、第３開口部６１の幅Ｌ３が、第１開口部３１の幅Ｌ１と同じである。ここで、第３開口部６１の幅Ｌ３は、持手部２０の長手方向（Ｘ方向）における第３開口部６１の長さ（横幅）である。なお、第３開口部６１の幅Ｌ３が第１開口部３１の幅Ｌ１と同じであること、第３開口部６１の幅Ｌ３と第１開口部３１の幅Ｌ１とが、略同一であればよく、全くの同一でなくてもよい。なお、第３開口部６１が第１開口部３１に重なる部分は、持手部２０の指掛部３０を構成する観点から、第１開口部３１の幅Ｌ１の約８０％以上を占める部分となることが好ましい。 In addition, in the packaging bag 100 of the second embodiment, the width L3 of the third opening 61 is the same as the width L1 of the first opening 31. Here, the width L3 of the third opening 61 is the length (width) of the third opening 61 in the longitudinal direction (X direction) of the handle portion 20. If the width L3 of the third opening 61 is the same as the width L1 of the first opening 31, and the width L3 of the third opening 61 and the width L1 of the first opening 31 are substantially the same. Well, it doesn't have to be exactly the same. The portion where the third opening 61 overlaps the first opening 31 is a portion that occupies about 80% or more of the width L1 of the first opening 31 from the viewpoint of configuring the finger hook 30 of the handle portion 20. It is preferable that

第２実施形態では、可撓性部材６０は、持手部２０に接着されている。具体的には、上述のようにシール部５０に囲まれた持手部２０中央領域２５に、可撓性部材６０がシール部５０により接着されている。 In the second embodiment, the flexible member 60 is adhered to the handle portion 20. Specifically, the flexible member 60 is bonded to the central region 25 of the handle portion 20 surrounded by the seal portion 50 as described above by the seal portion 50.

より具体的には、図８、図９に示すように、可撓性部材６０の周端を、シール部５０の一部（上端シール５１、下端シール５２、側端シール５３、側端シール５４、及び中間シール５５）で持手部２０の一方の面２０Ａに融着する（図９参照）。 More specifically, as shown in FIG. 8 and FIG. 9, the peripheral end of the flexible member 60 is provided at a part of the seal portion 50 (upper end seal 51, lower end seal 52, side end seal 53, side end seal 54). , And an intermediate seal 55) on the one surface 20A of the handle portion 20 (see FIG. 9).

なお、持手部２０に可撓性部材６０を接着する態様は、第２実施形態に限定されない。例えば、持手部２０の一方の面２０Ａに可撓性部材６０を接着する代わりに、持手部２０の他方の面２０Ｂに可撓性部材６０を接着してもよい。また、持手部２０の両面２０Ａ、２０Ｂにそれぞれ可撓性部材６０を接着してもよい。 The manner in which the flexible member 60 is bonded to the handle portion 20 is not limited to the second embodiment. For example, instead of bonding the flexible member 60 to the one surface 20A of the handle portion 20, the flexible member 60 may be bonded to the other surface 20B of the handle portion 20. Further, the flexible members 60 may be adhered to both surfaces 20A and 20B of the handle portion 20, respectively.

第２実施形態では、上述のように弾性部材４０を蓋う可撓性部材６０が持手部２０に形成され、弾性部材４０に形成された第２開口部４１に対して可撓性部材６０に形成された第３開口部６１が重なっている（図８、図９参照）。このような構成により、第３開口部６１にも手指等Ｐを通すことができる。そして、該手指等Ｐで持手部２０を掴む（または握る）ことができる。このように、第２実施形態では、第３開口部６１は、第１開口部３１および第２開口部４１とともに持手部２０の指掛部３０を構成することができる。 In the second embodiment, the flexible member 60 that covers the elastic member 40 is formed in the handle portion 20 as described above, and the flexible member 60 is provided with respect to the second opening portion 41 formed in the elastic member 40. The third opening 61 formed in the upper part overlaps (see FIGS. 8 and 9). With such a configuration, the fingers or the like P can be passed through the third opening 61. Then, the holding portion 20 can be grasped (or grasped) by the fingers P or the like. As described above, in the second embodiment, the third opening 61 can form the finger hook 30 of the handle portion 20 together with the first opening 31 and the second opening 41.

また、第２実施形態では、弾性部材４０を蓋う可撓性部材６０が持手部２０に形成されているため、可撓性部材６０が持手部２０に構成される指掛部３０を補強することができる。また、弾性部材４０は、可撓性部材６０と持手部２０の中央領域２５との間に挟み込まれているため、持手部２０を掴んだ（または握った）ときに弾性部材４０の一部のみが手指等Ｐに当たる。そのため、第２実施形態によれば、可撓性部材６０によって弾性部材４０を保護することができる。 In addition, in the second embodiment, since the flexible member 60 that covers the elastic member 40 is formed in the handle portion 20, the flexible member 60 is provided in the handle portion 20. Can be reinforced. In addition, since the elastic member 40 is sandwiched between the flexible member 60 and the central region 25 of the handle portion 20, when the handle portion 20 is gripped (or grasped), the elastic member 40 does not move. Only the part hits the finger or the like P. Therefore, according to the second embodiment, the elastic member 40 can be protected by the flexible member 60.

また、第２実施形態では、可撓性部材６０に形成された第３開口部６１の幅Ｌ３が持手部２０（中央領域２５）に形成された第１開口部３１の幅Ｌ１と同じであるため、該第３開口部６１の幅Ｌ３は、弾性部材４０に形成された第２開口部４１の幅Ｌ２より長いものとなる。そのため、第２実施形態によれば、持手部２０に可撓性部材６０を形成した場合でも、第３開口部６１への手指等Ｐの挿入が妨げられるのを防ぐことができる。 Further, in the second embodiment, the width L3 of the third opening 61 formed in the flexible member 60 is the same as the width L1 of the first opening 31 formed in the handle portion 20 (central region 25). Therefore, the width L3 of the third opening 61 is longer than the width L2 of the second opening 41 formed in the elastic member 40. Therefore, according to the second embodiment, even when the flexible member 60 is formed on the handle portion 20, it is possible to prevent the insertion of the finger P or the like from being inserted into the third opening 61.

また、第２実施形態では、弾性部材４０に形成された第２開口部４１の幅Ｌ２は、持手部２０（中央領域２５）に形成された第１開口部３１の幅Ｌ１および可撓性部材６０に形成された第３開口部６１の幅Ｌ３のいずれに対しても短いものとなる。そのため、第１開口部３１、第２開口部４１、及び第３開口部６１に挿入した手指等Ｐが、弾性部材４０に形成された第２開口部４１に当たりやすくなる。すなわち、該挿入した手指等Ｐは、持手部２０（中央領域２５）に形成された第１開口部３１および可撓性部材６０に形成された第３開口部６１のいずれにも当たりにくくなる。 Further, in the second embodiment, the width L2 of the second opening 41 formed in the elastic member 40 is equal to the width L1 of the first opening 31 formed in the handle portion 20 (central region 25) and the flexibility. The width is shorter than the width L3 of the third opening 61 formed in the member 60. Therefore, the fingers or the like P inserted into the first opening 31, the second opening 41, and the third opening 61 easily come into contact with the second opening 41 formed in the elastic member 40. That is, the inserted finger P or the like is less likely to hit either the first opening 31 formed in the handle portion 20 (center region 25) or the third opening 61 formed in the flexible member 60. ..

このように、第２実施形態では、持手部２０に可撓性部材６０を形成した場合でも、持手部２０を掴んだ際に手指等Ｐにかかる負荷をさらに和らげる（または緩和する）ことができる。そのため、第２実施形態によれば、持手部２０に形成された可撓性部材６０によって手指等Ｐが締め付けられたり、手指等Ｐが痛くなるのを抑制する（持手部２０が掴みやすくなり、包装袋１００の持ち運びが容易になる）効果を高めることができる。 As described above, in the second embodiment, even when the flexible member 60 is formed on the handle portion 20, it is possible to further reduce (or reduce) the load applied to the fingers P when the handle portion 20 is gripped.
