Description

本発明は、物品を包装する袋に関する。 The present invention relates to a bag for packaging an article.

緩衝材の一つとして、直線状に延びる複数の切れ込み部が千鳥状に設けられたシートが知られている。このシートは、その延在平面において切れ込み部の延びる方向に対して直交する方向に伸長させると、切れ込み部に対応する目が蜂の巣状に開く（このことから「ハニーペーパー」とも称される）。これにより、このシートは、厚み方向の寸法が増大して緩衝代の形成されたマット状に変化する（機能に着目して「クッションペーパー」とも称される）。このようなシートが緩衝部として内装された包装具も提案されている（特許文献１参照）。 As one of the cushioning materials, a sheet in which a plurality of linearly extending notches are provided in a staggered manner is known. When this sheet is extended in a direction orthogonal to the extending direction of the notch in its extending plane, the eyes corresponding to the notch open like a honeycomb (hence the name "honey paper"). As a result, the sheet changes into a mat-like shape in which a cushioning allowance is formed by increasing the dimension in the thickness direction (also referred to as "cushion paper" focusing on its function). A packaging tool in which such a sheet is incorporated as a shock absorber has also been proposed (see Patent Document 1).

緩衝部３をなす内装材３０は、切れ込み部３１の延在する所定方向と交差する方向（以下、単に交差方向ともいう）に引っ張られた場合に、切れ込み部３１に対応する目が開くことで交差方向に伸長する。 [Cushioning unit]
Next, the shock absorber 3 of the packaging bag 1 will be described.
As shown in FIG. 1, the cushioning portion 3 is a sheet-shaped interior material (first) in which a plurality of notches (first notches) 31 extending in a predetermined direction (first predetermined direction) are provided in a staggered manner. It is a cushioning material composed of (interior material) 30, and is also called honey paper or cushion paper.
When the interior material 30 forming the cushioning portion 3 is pulled in a direction intersecting a predetermined direction in which the notch portion 31 extends (hereinafter, also simply referred to as an intersection direction), the eyes corresponding to the notch portion 31 are opened. It extends in the crossing direction.

緩衝部３は、本体袋２の内側の面に取り付けられる。本体袋２が二重構造をなす場合は、緩衝部３が本体袋２の内袋２０に取り付けられる。ここでは、接着剤や粘着剤を介して内袋２０に貼り付けられた緩衝部３を例示する。
緩衝部３は、内装材３０が交差方向に伸長可能な状態又は予め伸長した状態で本体袋２に内装されたものである。本実施形態では、本体袋２の第一面部１１，２１と第二面部１２，２２との間に架け渡された内装材３０が交差方向に伸長可能な状態で設けられた緩衝部３を例示する。 The cushioning portion 3 is attached to the inner surface of the main body bag 2. When the main body bag 2 has a double structure, the shock absorber 3 is attached to the inner bag 20 of the main body bag 2. Here, the cushioning portion 3 attached to the inner bag 20 via an adhesive or an adhesive is exemplified.
The cushioning portion 3 is installed in the main body bag 2 in a state in which the interior material 30 can be extended in the crossing direction or is extended in advance. In the present embodiment, the cushioning portion 3 provided in a state in which the interior material 30 bridged between the first surface portions 11 and 21 and the second surface portions 12 and 22 of the main body bag 2 can be extended in the crossing direction is provided. Illustrate.

図２に示すように、緩衝部３は、切れ込み部３１の延びる所定方向が包装袋１の幅方向に沿う姿勢で、第一内面部２１の上端縁部２３と第二内面部２２の上端縁部２４との間に懸架されている。すなわち、緩衝部３は、所定方向が物品の挿抜方向と交差する姿勢で、本体袋２における第一面部１１，２１の上端縁部１３，２３と第二面部１２，２２の上端縁部１４，２４との間に懸架されている。そして、このように懸架された緩衝部３は、第一内面部２１の上端縁部２３と第二内面部２２の上端縁部２４との各々に貼り付けられている。 As shown in FIG. 2, the cushioning portion 3 has a posture in which a predetermined direction in which the notch portion 31 extends is along the width direction of the packaging bag 1, and the upper end edge portion 23 of the first inner surface portion 21 and the upper end edge of the second inner surface portion 22. It is suspended from the part 24. That is, the cushioning portion 3 is in a posture in which a predetermined direction intersects the insertion / removal direction of the article, and the upper end edges 13 and 23 of the first surface portions 11 and 21 and the upper end edges 14 of the second surface portions 12 and 22 in the main body bag 2. , 24 is suspended. The cushioning portion 3 suspended in this way is attached to each of the upper end edge portion 23 of the first inner surface portion 21 and the upper end edge portion 24 of the second inner surface portion 22.

本実施形態の緩衝部３は、包装する物品と本体袋２との間で複数枚の内装材３０が厚み方向に重ねられた多層部３Ａを全体に有する。換言すると、本実施形態では緩衝部３の全体が多層部３Ａである。ここでは、多層部３Ａで二枚の内装材３０が重ねられており、これらの内装材３０の所定方向が互いに同じ向き（本実施形態では幅方向）に設定された緩衝部３を例示する。
緩衝部３を二重（多重）構造とすることで、緩衝性をより高められる。 The cushioning portion 3 of the present embodiment has a multi-layered portion 3A in which a plurality of interior materials 30 are stacked in the thickness direction between the article to be packaged and the main body bag 2. In other words, in the present embodiment, the entire buffer portion 3 is the multilayer portion 3A. Here, an example is a cushioning portion 3 in which two interior materials 30 are overlapped with each other in the multilayer portion 3A, and the predetermined directions of the interior materials 30 are set to the same orientation (in the present embodiment, the width direction).
By forming the cushioning portion 3 in a double (multiplexed) structure, the cushioning property can be further enhanced.

緩衝部３をなす内装材３０は、下方に向けて凸のＶ字状となるように二つ折りにされている。緩衝部３では、上記のように二つ折りにされた内装材３０の二つの上端部である貼付端部３３，３４が、第一内面部２１及び第二内面部２２の上端縁部２３，２４にそれぞれ貼り付けられ、貼付端部３３，３４の間で吊り下げられた本体部３５が何れの部位にも貼り付けられずに配置される。なお、多層部３Ａにおいて重ねられた二枚の内装材３０は、貼付端部３３，３４で互いに貼り合わせられている。
以下、緩衝部３の二つの貼付端部３３，３４のうち、第一内面部２１の上端縁部２３に貼り付けられた一方を第一貼付端部３３ともいい、第二内面部２２の上端縁部２４に貼り付けられた他方を第二貼付端部３４ともいう。 The interior material 30 forming the cushioning portion 3 is folded in half so as to form a V-shape that is convex downward. In the cushioning portion 3, the pasted end portions 33, 34, which are the two upper end portions of the interior material 30 folded in half as described above, are the upper end edge portions 23, 24 of the first inner surface portion 21 and the second inner surface portion 22. The main body portion 35, which is attached to each of the attachment ends 33 and 34 and suspended between the attachment end portions 33 and 34, is arranged without being attached to any portion. The two interior materials 30 stacked in the multilayer portion 3A are bonded to each other at the pasting end portions 33 and 34.
Hereinafter, of the two sticking end portions 33 and 34 of the cushioning portion 3, one of the two sticking end portions 33 and 34 attached to the upper end edge portion 23 of the first inner surface portion 21 is also referred to as a first sticking end portion 33, and the upper end of the second inner surface portion 22. The other attached to the edge portion 24 is also referred to as a second affixed end portion 34.

切れ込み部３１は、少なくとも本体部３５に設けられる。図３に示すように、本体部３５は、開口９から包装袋１に入れられた物品８が載せられることで、物品８の重量によって長さ方向に伸長する。つまり、緩衝部３は、物品８が入れられる前（未使用時）の包装袋１では伸長していない状態（未伸長状態）であり、物品８が入れられた後（使用時）の包装袋１では長さ方向に伸長した状態（伸長状態）となる。なお、緩衝部３は、伸長状態となっても本体袋２の下端部と接触しないように構成される。 The notch 31 is provided at least in the main body 35. As shown in FIG. 3, the main body 35 is extended in the length direction by the weight of the article 8 by placing the article 8 put in the packaging bag 1 through the opening 9. That is, the shock absorber 3 is not stretched (unstretched state) in the packaging bag 1 before the article 8 is put in (when not in use), and is in the packaging bag after the article 8 is put in (when in use). In 1, it is in a state of being extended in the length direction (extended state). The cushioning portion 3 is configured so as not to come into contact with the lower end portion of the main body bag 2 even in the extended state.

図４に示すように、未伸長状態の本体部３５では、複数の切れ込み部３１が所定方向（本実施形態では幅方向）に沿って断続的に並設されており、所定方向に隣接する切れ込み部３１どうしの間には、切り込まれていない非切れ込み部３２が設けられている。切れ込み部３１の所定方向の寸法Ｌ１は、非切れ込み部３２の所定方向の寸法Ｌ２よりも大きく設定される（Ｌ１＞Ｌ２）。 As shown in FIG. 4, in the main body portion 35 in the unextended state, a plurality of cut portions 31 are intermittently arranged side by side along a predetermined direction (in the present embodiment, the width direction), and the cuts adjacent to the predetermined direction are arranged side by side. A non-cut portion 32 that is not cut is provided between the portions 31. The dimension L1 in the predetermined direction of the notch portion 31 is set to be larger than the dimension L2 in the predetermined direction of the non-notch portion 32 (L1> L2).

ここで、切れ込み部３１及び非切れ込み部３２が所定方向に沿って交互に並ぶ一行の配置を第一パターンＰ１とする。また、第一パターンＰ１の切れ込み部３１及び非切れ込み部３２とは半ピッチずれた切れ込み部３１′及び非切れ込み部３２′が所定方向に沿って交互に並ぶ他行の配置を第二パターンＰ２とする。これらの第一パターンＰ１及び第二パターンＰ２は、所定方向と直交する方向（本実施形態では長さ方向）において交互に並設される。 Here, the arrangement of one line in which the cut portions 31 and the non-cut portions 32 are alternately arranged along a predetermined direction is defined as the first pattern P1. Further, the arrangement of the other lines in which the notch portion 31'and the non-notch portion 32' that are half pitch-shifted from the notch portion 31 and the non-notch portion 32 of the first pattern P1 are alternately arranged along a predetermined direction is referred to as the second pattern P2. do. These first pattern P1 and second pattern P2 are arranged side by side alternately in a direction orthogonal to a predetermined direction (in the present embodiment, a length direction).

このような切れ込み部３１，３１′及び非切れ込み部３２，３２′が設けられた内装材３０は、切れ込み部３１，３１′に対応した形状の刃部（カッタ）が外周に設けられたロータリダイカッタによって、切れ込まれていないシート材を回転しながら切り込むことで製造される。または、切れ込み部３１，３１′に対応した形状の刃部が設けられた平板ダイカッタによって、切り込まれていないシート材をプレスしながら切り込むことで、内装材３０が製造される。 The interior material 30 provided with such notched portions 31, 31'and non-notched portions 32, 32'is a rotary die provided with a blade portion (cutter) having a shape corresponding to the notched portions 31, 31'. It is manufactured by cutting the uncut sheet material while rotating it with a cutter. Alternatively, the interior material 30 is manufactured by cutting while pressing the uncut sheet material with a flat plate die cutter provided with a blade portion having a shape corresponding to the cut portions 31, 31'.

図５に示すように、伸長状態の本体部３５では、切れ込み部３１の周囲の片部３６が厚み方向に立ち上がることで立体状の緩衝セル３７が形成される。このように、伸長状態の本体部３５では、一つの切れ込み部３１に対し、その周囲の片部３６が立ち上がることで一つの緩衝セル３７が出現する。
したがって、緩衝部３は、本体部３５が図２に示すような未伸長状態である場合にはシート状をなすのに対し、本体部３５が図３に示すような伸長状態である場合にはシート状よりも厚みが増したマット状をなす。マット状の緩衝部３には、緩衝用の変形代（緩衝代）が設けられることから緩衝性が確保される。なお、交差方向に伸長することでシート状からマット状に変化した緩衝部３は、復元力で僅かに復元する（片部３６の立ち上がりが戻る）ことはあっても、基本的には再びシート状となることはない。 As shown in FIG. 5, in the main body portion 35 in the extended state, the three-dimensional buffer cell 37 is formed by the one portion 36 around the notch portion 31 rising in the thickness direction. As described above, in the main body portion 35 in the extended state, one buffer cell 37 appears when the one portion 36 around the notch portion 31 stands up.
Therefore, the cushioning portion 3 has a sheet shape when the main body portion 35 is in the unextended state as shown in FIG. 2, whereas the main body portion 35 is in the extended state as shown in FIG. It has a matte shape that is thicker than a sheet. Since the mat-shaped cushioning portion 3 is provided with a deformation allowance (buffering allowance) for cushioning, cushioning property is ensured. The cushioning portion 3 which has changed from a sheet shape to a mat shape by extending in the crossing direction may be slightly restored by the restoring force (the rising edge of one portion 36 returns), but basically the sheet is again. It does not become a state.

ここで図２を参照し、本体袋２をなす外袋１０及び内袋２０と、緩衝部３をなす内装材３０との関係について詳述する。
上記のとおり、本実施形態の内袋２０は、第一内面部２１及び第二内面部２２の各上端縁部２３，２４において緩衝部３に貼り付けられているとともに、各上端縁部２３，２４よりも下方に位置する下端部において外袋１０に貼り付けられている。すなわち、内袋２０は、外袋１０への貼付位置が下端部であるのに対し、緩衝部３への貼付位置が第一内面部２１及び第二内面部２２の各上端縁部２３，２４である。したがって、内袋２０は、厚み方向視において、外袋１０に対する貼付位置と緩衝部３に対する貼付位置とが異なっている。 Here, with reference to FIG. 2, the relationship between the outer bag 10 and the inner bag 20 forming the main body bag 2 and the interior material 30 forming the cushioning portion 3 will be described in detail.
As described above, the inner bag 20 of the present embodiment is attached to the cushioning portion 3 at the upper end edge portions 23 and 24 of the first inner surface portion 21 and the second inner surface portion 22, and the upper end edge portions 23, respectively. It is attached to the outer bag 10 at the lower end portion located below 24. That is, the inner bag 20 is attached to the outer bag 10 at the lower end, whereas the inner bag 20 is attached to the cushioning portion 3 at the upper end edges 23 and 24 of the first inner surface portion 21 and the second inner surface portion 22. Is. Therefore, the inner bag 20 has a different attachment position with respect to the outer bag 10 and an attachment position with respect to the cushioning portion 3 in the thickness direction.

〔外フラップ〕
図１〜３に示すように、外フラップ４は、本体袋２の第一面部１１，２１から上方へ突設される。ここでは、第一外面部１１から上方へ突設された外フラップ４を例示する。外フラップ４は、第一外面部１１の上端縁部１３と連設されている。
外フラップ４は、本体袋２の第一面部１１，２１から第二面部１２，２２側へと折り返され、本体袋２の第二面部１２，２２よりも外側に配置されて開口９を覆う。包装袋１は、このように開口９を覆う外フラップ４が本体袋２の外側の面（本実施形態では第二外面部１２）に固定されることにより封緘状態となる。なお、内フラップ５が設けられた包装袋１の封緘状態では、外フラップ４が内フラップ５よりも外側に配置される。 [Outer flap]
As shown in FIGS. 1 to 3, the outer flap 4 is projected upward from the first surface portions 11 and 21 of the main body bag 2. Here, an outer flap 4 projecting upward from the first outer surface portion 11 is illustrated. The outer flap 4 is connected to the upper end edge portion 13 of the first outer surface portion 11.
The outer flap 4 is folded back from the first surface portions 11 and 21 of the main body bag 2 to the second surface portions 12 and 22 sides, and is arranged outside the second surface portions 12 and 22 of the main body bag 2 to cover the opening 9. .. The packaging bag 1 is in a sealed state when the outer flap 4 covering the opening 9 is fixed to the outer surface of the main body bag 2 (second outer surface portion 12 in the present embodiment). In the sealed state of the packaging bag 1 provided with the inner flap 5, the outer flap 4 is arranged outside the inner flap 5.

〔内フラップ〕
必要に応じて設けられる内フラップ５は、所定方向（第二所定方向）に延在する複数の切れ込み部５１（第二切れ込み部）が千鳥状に設けられたシート状の内装材（第二内装材）５０で構成された緩衝材であってもよい。このような緩衝材である内フラップ５をなす内装材５０は、緩衝部３をなす内装材３０と同様に構成されており、ハニーペーパーやクッションペーパーなどとも称される。内装材５０は、切れ込み部５１の延在する所定方向と交差する交差方向に引っ張られた場合に、切れ込み部５１に対応する目が開くことで伸長する。 [Inner flap]
The inner flap 5 provided as needed is a sheet-shaped interior material (second interior) in which a plurality of notches 51 (second notches) extending in a predetermined direction (second predetermined direction) are provided in a staggered manner. Material) It may be a cushioning material composed of 50. The interior material 50 forming the inner flap 5 which is such a cushioning material has the same structure as the interior material 30 forming the cushioning portion 3, and is also referred to as honey paper or cushion paper. When the interior material 50 is pulled in an intersecting direction intersecting a predetermined direction in which the notch 51 extends, the interior material 50 extends by opening the eyes corresponding to the notch 51.

図１〜３に示す内フラップ５は、一枚のシート状の内装材５０が交差方向（第二所定方向と交差する方向）に伸長可能な状態予め伸長した状態で設けられたものである。本実施形態では、緩衝部３から揺動自在に突設された未伸長状態の内装材５０が交差方向に伸長可能な状態で設けられた内フラップ５を例示する。
このように未伸長状態で設けられた内装材５０は、例えばユーザによって交差方向に引っ張られることで伸長状態となる。これにより、内フラップ５は、シート状からマット状に変形する。マット状の内フラップ５には、マット状の緩衝部３と同様に、緩衝用の変形代（緩衝代）が設けられることから緩衝性が確保される。 The inner flaps 5 shown in FIGS. 1 to 3 are provided in a state in which one sheet-shaped interior material 50 is stretchable in a crossing direction (direction intersecting with a second predetermined direction) and is stretched in advance. In the present embodiment, the inner flap 5 provided in a state in which the unextended interior material 50 projecting from the cushioning portion 3 so as to be able to extend in the crossing direction is exemplified.
The interior material 50 provided in the unstretched state is brought into the stretched state by being pulled in the crossing direction by, for example, the user. As a result, the inner flap 5 is deformed from a sheet shape to a mat shape. Similar to the mat-shaped cushioning portion 3, the mat-shaped inner flap 5 is provided with a deformation allowance (buffering allowance) for cushioning, so that cushioning property is ensured.

本実施形態の内フラップ５は、緩衝部３と連設されている。すなわち、内フラップ５と緩衝部３とは、一体であって互いに連続している（離間していない）。ここでは、緩衝部３において厚み方向に重なる複数の内装材３０のうち、最も外側に配置された内装材３０と内フラップ５とが単一の部材で形成された例を示す。
内フラップ５は、緩衝部３と同様に、切れ込み部５１の延びる所定方向が包装袋１の幅方向に沿う（所定方向が物品の挿抜方向と交差する）姿勢で設けられている。ただし、緩衝部３の切れ込み部３１が延びる所定方向と、内フラップ５の切れ込み部５１が延びる所定方向とは、包装袋１の幅方向と交差していてもよいし、互いに異なっていてもよい。なお、包装袋１に設けられる内フラップ５の個数は特に限定されないが、ここでは一つの内フラップ５が設けられた包装袋１を示す。 The inner flap 5 of the present embodiment is connected to the shock absorber 3. That is, the inner flap 5 and the cushioning portion 3 are integrated and continuous with each other (not separated from each other). Here, an example is shown in which the interior material 30 and the inner flap 5 arranged on the outermost side of the plurality of interior materials 30 overlapping in the thickness direction in the cushioning portion 3 are formed of a single member.
Like the cushioning portion 3, the inner flap 5 is provided in a posture in which a predetermined direction in which the notch portion 51 extends is along the width direction of the packaging bag 1 (the predetermined direction intersects the insertion / removal direction of the article). However, the predetermined direction in which the notch 31 of the cushioning portion 3 extends and the predetermined direction in which the notch 51 of the inner flap 5 extends may intersect with the width direction of the packaging bag 1 or may be different from each other. .. The number of inner flaps 5 provided in the packaging bag 1 is not particularly limited, but here, the packaging bag 1 provided with one inner flap 5 is shown.

本実施形態の内フラップ５は、本体袋２における第一面部１１，２１の上端縁部１３，２３と第二面部１２，２２の上端縁部１４，２４とのうち、外フラップ４が突設された一方とは反対側の他方に貼り付けられた対向フラップ５Ｃである。対向フラップ５Ｃは、緩衝部３の第二貼付端部３４から突設されている。このように、本実施形態では、第一外面部１１の上端縁部１３から突設された外フラップ４に対し、対向フラップ５Ｃである内フラップ５が第二内面部２２の上端縁部２４に貼り付けられている。 In the inner flap 5 of the present embodiment, the outer flap 4 protrudes from the upper end edges 13 and 23 of the first surface portions 11 and 21 and the upper end edges 14 and 24 of the second surface portions 12 and 22 in the main body bag 2. It is an opposed flap 5C attached to the other side opposite to the one provided. The opposed flap 5C is projected from the second sticking end portion 34 of the cushioning portion 3. As described above, in the present embodiment, the inner flap 5 which is the facing flap 5C is attached to the upper end edge portion 24 of the second inner surface portion 22 with respect to the outer flap 4 projecting from the upper end edge portion 13 of the first outer surface portion 11. It is pasted.

図３に示すように、内フラップ５は、包装袋１の封緘前に交差方向に伸長させられる。これによりマット状に変形した内フラップ５は、緩衝部３から本体袋２の第一面部１１，２１側へと折り返され、緩衝部３の第一貼付端部３３の内側に配置されて物品８を上側（開口９側）から覆う。内フラップ５は、包装袋１の封緘状態では、物品８と外フラップ４との間に配置され、物品８の上側の緩衝機能を担う。
なお、必要に応じて設けられる内フラップ５は、外フラップ４よりも内側で物品８を開口９側から覆う構造であれば特に限定されない。内フラップ５は、本体袋２の第二面部１２，２２の上端縁部１４，２４に繋がっていてもよいし、緩衝部３の第一貼付端部３３に繋がっていてもよい。 As shown in FIG. 3, the inner flap 5 is extended in the crossing direction before sealing the packaging bag 1. The inner flap 5 deformed into a mat shape is folded back from the cushioning portion 3 toward the first surface portions 11 and 21 of the main body bag 2, and is arranged inside the first sticking end portion 33 of the cushioning portion 3 to be an article. 8 is covered from the upper side (opening 9 side). The inner flap 5 is arranged between the article 8 and the outer flap 4 in the sealed state of the packaging bag 1 and serves as a cushioning function on the upper side of the article 8.
The inner flap 5 provided as needed is not particularly limited as long as it has a structure that covers the article 8 from the opening 9 side inside the outer flap 4. The inner flap 5 may be connected to the upper end edges 14 and 24 of the second surface portions 12 and 22 of the main body bag 2, or may be connected to the first sticking end portion 33 of the cushioning portion 3.

［２．作用及び効果］
（１）緩衝部３は、物品８と本体袋２との間で複数枚の内装材３０が厚み方向に重ねられた多層部３Ａを少なくとも一部に有するため、多層部３Ａを有しない場合と比べて、少なくとも一部で緩衝性を高められる。これにより、緩衝部３の一部に荷重が集中するような場合であっても、緩衝部３が耐えられることから物品８の保護性を向上させられる。よって、包装袋１の信頼性を高められる。 [2. Action and effect]
(1) Since the cushioning portion 3 has a multilayer portion 3A in which a plurality of interior materials 30 are stacked in the thickness direction between the article 8 and the main body bag 2, the cushioning portion 3 does not have the multilayer portion 3A. In comparison, the cushioning property can be enhanced at least in part. As a result, even when the load is concentrated on a part of the cushioning portion 3, the cushioning portion 3 can withstand the load, so that the protection property of the article 8 can be improved. Therefore, the reliability of the packaging bag 1 can be enhanced.

（２）緩衝部３がその全体に多層部３Ａを有するため、緩衝部３の全体において緩衝性を高められる。これにより、物品８の保護性が緩衝部３の全体で向上することから、包装袋１の信頼性をより高められる。 (2) Since the buffer portion 3 has the multilayer portion 3A as a whole, the cushioning property can be enhanced in the entire buffer portion 3. As a result, the protection of the article 8 is improved in the entire cushioning portion 3, so that the reliability of the packaging bag 1 can be further enhanced.

（３）多層部３Ａで重ねられた複数枚の内装材３０は所定方向が互いに同じ向きに設定されているため、これらの内装材３０を一体的に交差方向に引っ張ることで多層部３Ａを一斉に伸長させることが可能となる。よって、シート状の緩衝部３を伸長させてマット状に変形させる作業が容易となる。
したがって、内装材３０が交差方向に伸長可能な状態で設けられる緩衝部３を備えた包装袋１の使用性を高められる。また、内装材３０が交差方向に予め伸長した状態で設けられる緩衝部３を備えた包装袋１の製造容易性を高められる。 (3) Since the predetermined directions of the plurality of interior materials 30 stacked in the multilayer portion 3A are set to be the same as each other, the multilayer portions 3A are simultaneously pulled by pulling the interior materials 30 integrally in the crossing direction. Can be extended to. Therefore, the work of extending the sheet-shaped cushioning portion 3 and deforming it into a mat-like shape becomes easy.
Therefore, the usability of the packaging bag 1 provided with the cushioning portion 3 provided so that the interior material 30 can be extended in the crossing direction can be enhanced. Further, it is possible to improve the ease of manufacturing the packaging bag 1 provided with the cushioning portion 3 provided in the state where the interior material 30 is preliminarily extended in the crossing direction.

（４）緩衝部３は、所定方向が物品８の挿抜方向と交差する姿勢で第一内面部２１の上端縁部２３と第二内面部２２の上端縁部２４との間に懸架されているため、内装材３０が包装袋１への物品８の挿入に伴って伸長可能となる。よって、物品８の挿入前（包装袋１の使用前）には内装材３０がシート状をなすことで包装袋１の厚みを抑制できるとともに、物品８の挿入後（包装袋１の使用時）には内装材３０が伸長してマット状をなすことで緩衝部３の緩衝性を確保できる。 (4) The cushioning portion 3 is suspended between the upper end edge portion 23 of the first inner surface portion 21 and the upper end edge portion 24 of the second inner surface portion 22 in a posture in which a predetermined direction intersects the insertion / removal direction of the article 8. Therefore, the interior material 30 can be extended with the insertion of the article 8 into the packaging bag 1. Therefore, before the article 8 is inserted (before the packaging bag 1 is used), the interior material 30 forms a sheet shape, so that the thickness of the packaging bag 1 can be suppressed and after the article 8 is inserted (when the packaging bag 1 is used). The cushioning property of the cushioning portion 3 can be ensured by extending the interior material 30 to form a mat shape.

［３．変形例］
以下、包装袋の変形例について説明する。変形例の説明では、上記の実施形態や他の変形例で説明した要素と同一又は対応する要素に同一の符号を付し、重複する説明を省略する。 [3. Modification example]
Hereinafter, a modified example of the packaging bag will be described. In the description of the modified example, the same or corresponding elements as those described in the above-described embodiment and other modified examples are designated by the same reference numerals, and duplicate description will be omitted.

［３−１．第一変形例］
図６に示すように、第一変形例に係る包装袋１Ａは、上記の実施形態に係る包装袋１に対し、緩衝部３′の内装材３０が交差方向に予め伸長した状態で本体袋２に内装されている点と、内フラップ５′が緩衝部３′とは別の部材で形成されている点とが異なる。
本変形例の緩衝部３′は、包装袋１Ａの製造過程で内装材３０が交差方向に引っ張られたうえで本体袋２に取り付けられたものである。緩衝部３′は、包装袋１Ａの使用時だけでなく使用前にもマット状をなす。 [3-1. First modification]
As shown in FIG. 6, the packaging bag 1A according to the first modification is a main body bag 2 in a state in which the interior material 30 of the cushioning portion 3'is preliminarily extended in the crossing direction with respect to the packaging bag 1 according to the above embodiment. The difference is that the inner flap 5'is made of a member different from the cushioning portion 3'.
The cushioning portion 3'of this modification is attached to the main body bag 2 after the interior material 30 is pulled in the crossing direction in the manufacturing process of the packaging bag 1A. The cushioning portion 3'forms a mat shape not only when the packaging bag 1A is used but also before use.

ここでは、第一内面部２１のほぼ全域と第二内面部２２のほぼ全域とのそれぞれに重ね合わされた緩衝部３′を例示する。緩衝部３′は、その全体に多層部３Ａを有する。なお、緩衝部３′は、伸長状態をより適切に維持するために、貼付端部３３，３４に加えて下端部３８も内袋２０に取り付けられていてもよい。
本変形例の緩衝部３′は、上記のとおり内装材３０が予め伸長した状態で設けられることから、切れ込み部３１の延在する所定方向が物品の挿抜方向と交差する姿勢で設けられなくてもよい。例えば、緩衝部３′は、所定方向が包装袋１Ａの長さ方向に沿った姿勢で設けられてもよい。 Here, a cushioning portion 3'overlaid on each of almost the entire area of the first inner surface portion 21 and the substantially entire area of the second inner surface portion 22 will be illustrated. The buffer portion 3'has a multilayer portion 3A as a whole. In addition, the lower end portion 38 of the cushioning portion 3'may be attached to the inner bag 20 in addition to the sticking end portions 33 and 34 in order to maintain the extended state more appropriately.
Since the cushioning portion 3'of this modification is provided in a state in which the interior material 30 is pre-extended as described above, the cushioning portion 3'is not provided in a posture in which the extending predetermined direction of the notch portion 31 intersects the insertion / removal direction of the article. May be good. For example, the cushioning portion 3'may be provided in a posture in which a predetermined direction is along the length direction of the packaging bag 1A.

本変形例では、内フラップ５′と緩衝部３′をなす少なくとも一枚の内装材３０とが、単一の部材で形成されておらず、包装袋１Ａの製造過程で例えば接着剤や粘着剤により互いに貼り合わせられている。ここでは、緩衝部３′の第二貼付端部３４の内側に配置されて第二貼付端部３４に貼り付けられた内フラップ５′を例示する。このように、別体であって互いに連続していない。連続している別単一の部材で形成されていない。なお、本変形例の内フラップ５′も対向フラップ５Ｃである。 In this modification, the inner flap 5'and at least one interior material 30 forming the cushioning portion 3'are not formed of a single member, and for example, an adhesive or an adhesive is used in the manufacturing process of the packaging bag 1A. Are pasted together by. Here, the inner flap 5'arranged inside the second sticking end portion 34 of the cushioning portion 3'and attached to the second sticking end portion 34 is exemplified. In this way, they are separate bodies and are not continuous with each other. It is not formed of a single continuous member. The inner flap 5'of this modification is also the opposed flap 5C.

包装袋１Ａによれば、内装材３０が交差方向に予め伸長した状態で本体袋２に内装された緩衝部３′を備えるため、使用前後にかかわらずマット状をなす緩衝部３′により緩衝性を適切に確保できる。
また、緩衝部３′とは別の部材で形成された内フラップ５′によれば、内フラップ５′の配置の自由度を高められる。具体的には、内フラップ５′を緩衝部３′とは独立して配置できるため、内フラップ５′の所定方向を緩衝部３′の所定方向と異ならせたり、内フラップ５′を緩衝部３′から離して配置したりすることが容易となる。よって、様々な形態の内フラップ５′を設けることが容易となる。
そのほか、本変形例の包装袋１Ａによれば、上記の実施形態の包装袋１と同様の構成からは、同様の作用及び効果が得られる。 According to the packaging bag 1A, since the interior material 30 is provided with the cushioning portion 3'interiored in the main body bag 2 in a state of being pre-extended in the crossing direction, the cushioning portion 3'which has a mat-like shape before and after use provides cushioning properties. Can be properly secured.
Further, according to the inner flap 5'formed by a member different from the cushioning portion 3', the degree of freedom in the arrangement of the inner flap 5'can be increased. Specifically, since the inner flap 5'can be arranged independently of the cushioning portion 3', the predetermined direction of the inner flap 5'is different from the predetermined direction of the cushioning portion 3', or the inner flap 5'is used as the cushioning portion. It becomes easy to arrange it away from 3'. Therefore, it becomes easy to provide the inner flaps 5'in various forms.
In addition, according to the packaging bag 1A of the present modification, the same operation and effect can be obtained from the same configuration as the packaging bag 1 of the above embodiment.

［３−２．第二変形例］
図７に示すように、第二変形例に係る包装袋１Ｂは、上記の第一変形例に係る包装袋１Ａに対し、緩衝部３′がその一部のみに多層部３Ａを有する点が異なる。より具体的に言えば、本変形例の緩衝部３′は、多層部３Ａの設けられた一部を除く他部に、物品と本体袋２との間で一枚の内装材３０が配置された単層部３Ｂを有する。ここでは、緩衝部３′の下半部（長さ方向の中間部よりも下側部分）に多層部３Ａが設定され、緩衝部３′の上半部（長さ方向の中間部よりも下側部分）に単層部３Ｂが設定された例を示す。 [3-2. Second variant]
As shown in FIG. 7, the packaging bag 1B according to the second modification is different from the packaging bag 1A according to the first modification in that the cushioning portion 3'has a multilayer portion 3A only in a part thereof. .. More specifically, in the cushioning portion 3'of this modification, one interior material 30 is arranged between the article and the main body bag 2 in other portions except for a part provided with the multilayer portion 3A. It has a single layer portion 3B. Here, the multilayer portion 3A is set in the lower half portion of the cushioning portion 3'(the portion below the middle portion in the length direction), and the upper half portion of the cushioning portion 3'(the portion below the middle portion in the length direction). An example in which the single layer portion 3B is set on the side portion) is shown.

ただし、多層部３Ａ及び単層部３Ｂの配置の設定はこれに限定されない。多層部３Ａは、緩衝部３′において緩衝性が相対的に（他部よりも）求められる一部に設定されればよい。換言すれば、単層部３Ｂは、緩衝部３′において緩衝性が相対的に（一部よりも）求められない他部に設定されればよい。多層部３Ａ及び単層部３Ｂの配置は、例えば、包装袋１Ｂが包装する物品の形状や、包装袋１Ｂの形状や、輸送時の包装袋１Ｂの姿勢などを勘案して設定されてもよい。 However, the setting of the arrangement of the multilayer portion 3A and the single layer portion 3B is not limited to this. The multilayer portion 3A may be set to a part of the cushioning portion 3'where the cushioning property is relatively required (compared to other portions). In other words, the single-layer portion 3B may be set in the other portion where the cushioning property is relatively (more than a part) not required in the cushioning portion 3'. The arrangement of the multi-layer portion 3A and the single-layer portion 3B may be set in consideration of, for example, the shape of the article to be packaged by the packaging bag 1B, the shape of the packaging bag 1B, the posture of the packaging bag 1B during transportation, and the like. ..

包装袋１Ｂによれば、緩衝部３′のうち、多層部３Ａを有する一部においてピンポイントに緩衝性を高められるとともに、単層部３Ｂを有する他部において材料及び重量を抑制できる。このため、多層部３Ａで物品の保護性を高めつつも、単層部３Ｂで材料コストを抑制できるとともに軽量化を図れる。
また、下半部に多層部３Ａが設定された緩衝部３′によれば、例えば重力により緩衝部３′の下端部３８側へ引っ張られる物品の緩衝性を高められる。このため、開口９が上向きの姿勢の包装袋１Ｂにおいて、物品の保護性を良好に確保できる。
そのほか、本変形例の包装袋１Ｂによれば、上記の第一変形例の包装袋１Ａと同様の構成からは、同様の作用及び効果が得られる。 According to the packaging bag 1B, the cushioning property can be pinpointly enhanced in a part of the cushioning portion 3'having the multilayer portion 3A, and the material and weight can be suppressed in the other portion having the single layer portion 3B. Therefore, while the multi-layered portion 3A enhances the protection of the article, the single-layered portion 3B can suppress the material cost and reduce the weight.
Further, according to the cushioning portion 3'in which the multilayer portion 3A is set in the lower half portion, for example, the cushioning property of the article pulled toward the lower end portion 38 side of the cushioning portion 3'by gravity can be enhanced. Therefore, in the packaging bag 1B in which the opening 9 is in an upward posture, the protection of the article can be sufficiently ensured.
In addition, according to the packaging bag 1B of the present modification, the same operation and effect can be obtained from the same configuration as the packaging bag 1A of the first modification.

［３−３．第三変形例］
図８に示すように、第三変形例に係る包装袋１Ｃは、上記の実施形態に係る包装袋１に対し、複数の内フラップ５を備える点が異なる。ここでは、開口９の両側にそれぞれ配置された二つの内フラップ５を備えた包装袋１Ｃを例示する。 [3-3. Third variant]
As shown in FIG. 8, the packaging bag 1C according to the third modification is different from the packaging bag 1 according to the above embodiment in that it is provided with a plurality of inner flaps 5. Here, a packaging bag 1C provided with two inner flaps 5 arranged on both sides of the opening 9 is illustrated.

本変形例の内フラップ５はいずれも、緩衝部３と連設されている。ここでは、緩衝部３において厚み方向に重なる複数の内装材３０のうち最も外側に配置された内装材３０と二つの内フラップ５とが、単一の部材で形成された例を示す。各々の内フラップ５は、上記の実施形態と同様に、内装材５０が交差方向に伸長可能な状態で設けられたものである。
以下、二つの内フラップ５のうち、開口９の一側（図８では右側）に配置された一方を第一内フラップ５Ａともいい、開口９の他側（図８では左側）に配置された他方を第二内フラップ５Ｂともいう。 The inner flaps 5 of this modification are all connected to the cushioning portion 3. Here, an example is shown in which the interior material 30 and the two inner flaps 5 arranged on the outermost side of the plurality of interior materials 30 overlapping in the thickness direction in the cushioning portion 3 are formed of a single member. Each inner flap 5 is provided in a state in which the interior material 50 can be extended in the crossing direction, as in the above embodiment.
Hereinafter, of the two inner flaps 5, one of the two inner flaps 5 arranged on one side of the opening 9 (right side in FIG. 8) is also referred to as a first inner flap 5A, and is arranged on the other side of the opening 9 (left side in FIG. 8). The other is also referred to as the second inner flap 5B.

第一内フラップ５Ａは、緩衝部３の第一貼付端部３３から突設されており、外フラップ４の内側に重なっている。第一内フラップ５Ａは、第一内面部２１の上端縁部２３（第一端縁部及び第二端縁部の一方）に貼り付けられている。
一方、第二内フラップ５Ｂは、上記の実施形態で説明した対向フラップ５Ｃであり、緩衝部３の第二貼付端部３４から突設されている。第二内フラップ５Ｂは、第二内面部２２の上端縁部２４（第一端縁部及び第二端縁部の他方）に貼り付けられている。 The first inner flap 5A projects from the first sticking end 33 of the cushioning portion 3 and overlaps the inside of the outer flap 4. The first inner flap 5A is attached to the upper end edge portion 23 (one of the first end edge portion and the second end edge portion) of the first inner surface portion 21.
On the other hand, the second inner flap 5B is the opposed flap 5C described in the above embodiment, and is projected from the second sticking end portion 34 of the cushioning portion 3. The second inner flap 5B is attached to the upper end edge portion 24 (the other end of the first end edge portion and the second end edge portion) of the second inner surface portion 22.

内フラップ５はいずれも、包装袋１Ｃの封緘前に交差方向に伸長させられる。これによりシート状からマット状に変形した第一内フラップ５Ａは、緩衝部３の第一貼付端部３３から本体袋２の第二面部１２，２２側へと折り返される。同様に、シート状からマット状に変形した第二内フラップ５Ｂは、緩衝部３の第二貼付端部３４から本体袋２の第一面部１１，２１側へと折り返される。そして、第一内フラップ５Ａ及び第二内フラップ５Ｂは、物品の外側で互いに重ねられ、物品を上側（開口９側）から覆う。 All of the inner flaps 5 are extended in the crossing direction before sealing the packaging bag 1C. As a result, the first inner flap 5A deformed from the sheet shape to the mat shape is folded back from the first sticking end portion 33 of the cushioning portion 3 to the second surface portions 12 and 22 sides of the main body bag 2. Similarly, the second inner flap 5B deformed from the sheet shape to the mat shape is folded back from the second sticking end portion 34 of the cushioning portion 3 to the first surface portions 11 and 21 sides of the main body bag 2. Then, the first inner flap 5A and the second inner flap 5B are overlapped with each other on the outer side of the article and cover the article from the upper side (opening 9 side).

包装袋１Ｃによれば、複数の内フラップ５が設けられるため、一つの内フラップ５が設けられる場合と比べて、物品８の開口９側における緩衝性を一層高められる。
また、第一内フラップ５Ａ及び第二内フラップ５Ｂが第一内面部２１の上端縁部２３と第二内面部２２の上端縁部２４とにそれぞれに貼り付けられるため、開口９の両側で互いに対向する二つの内フラップ５により、物品を開口９側から更に適切に覆うことができる。また、二つの内フラップ５が開口９に対して同一側に配置される場合と比べて、内フラップ５どうしが離間することで互いに干渉しにくくなる。これにより、各々の内フラップ５を物品８の開口９側に被せる作業が容易となるため、包装袋１Ｃの封緘作業性を高められる。
そのほか、本変形例の包装袋１Ｃによれば、上記の第一変形例の包装袋１Ａと同様の構成からは、同様の作用及び効果が得られる。 According to the packaging bag 1C, since the plurality of inner flaps 5 are provided, the cushioning property on the opening 9 side of the article 8 can be further enhanced as compared with the case where one inner flap 5 is provided.
Further, since the first inner flap 5A and the second inner flap 5B are attached to the upper end edge portion 23 of the first inner surface portion 21 and the upper end edge portion 24 of the second inner surface portion 22, respectively, they are attached to each other on both sides of the opening 9. The two opposing inner flaps 5 can more appropriately cover the article from the opening 9 side. Further, as compared with the case where the two inner flaps 5 are arranged on the same side with respect to the opening 9, the inner flaps 5 are separated from each other so that they are less likely to interfere with each other. This facilitates the work of covering each inner flap 5 on the opening 9 side of the article 8, so that the sealing workability of the packaging bag 1C can be improved.
In addition, according to the packaging bag 1C of the present modification, the same operation and effect can be obtained from the same configuration as the packaging bag 1A of the first modification.

［３−４．第四変形例］
図９に示すように、第四変形例に係る包装袋１Ｄは、上記の第三変形例に係る包装袋１Ｃに対し、第二内フラップ５Ｂが第一内フラップ５Ａに貼り付けられた点が異なる。すなわち、本変形例の包装袋１Ｄでは、二つの内フラップ５が開口９に対して同一側に配置され、互いに重ね合わされている。 [3-4. Fourth variant]
As shown in FIG. 9, in the packaging bag 1D according to the fourth modification, the second inner flap 5B is attached to the first inner flap 5A with respect to the packaging bag 1C according to the third modification. different. That is, in the packaging bag 1D of the present modification, the two inner flaps 5 are arranged on the same side with respect to the opening 9 and are overlapped with each other.

包装袋１Ｄによれば、第一内フラップ５Ａ及び第二内フラップ５Ｂを一体的に（一動作で）緩衝部３の第一貼付端部３３から本体袋２の第二面部１２，２２側へと折り返せることから、封緘作業性を高められる。また、複数の内フラップ５を開口９の一側のみに配置することで、物品の保護性を高めつつも、開口９に対する物品の挿抜作業性を高められる。よって、包装袋１Ｄの信頼性と使用性とを共に高められる。
そのほか、本変形例の包装袋１Ｄによれば、上記の第三変形例の包装袋１Ｃと同様の構成からは、同様の作用及び効果が得られる。 According to the packaging bag 1D, the first inner flap 5A and the second inner flap 5B are integrally (in one operation) from the first sticking end 33 of the cushioning portion 3 to the second surface portions 12 and 22 of the main body bag 2. Because it can be folded back, the sealing workability can be improved. Further, by arranging the plurality of inner flaps 5 only on one side of the opening 9, it is possible to improve the workability of inserting and removing the article into the opening 9 while improving the protection of the article. Therefore, both the reliability and usability of the packaging bag 1D can be enhanced.
In addition, according to the packaging bag 1D of the present modification, the same operation and effect can be obtained from the same configuration as the packaging bag 1C of the third modification.

［３−５．その他］
内装材３０，５０において切れ込み部３１，５１の延在する所定方向は、包装袋の幅方向に限定されない。例えば、内装材３０，５０は、所定方向が包装袋の長さ方向に沿う姿勢で設けられてもよい。 [3-5. others]
The predetermined direction in which the notches 31 and 51 extend in the interior materials 30 and 50 is not limited to the width direction of the packaging bag. For example, the interior materials 30 and 50 may be provided in a posture in which a predetermined direction is along the length direction of the packaging bag.

また、緩衝部３，３′の多層部３Ａで重ねられた複数枚の内装材３０は、所定方向が互いに異なる向きに設定されてもよい。例えば図１０に示すように、多層部３Ａで重ねられる二枚の内装材３０は、所定方向が包装袋の幅方向に対して傾斜するとともに、その傾斜方向が互いに反対となる（幅方向に対する傾斜角度の正負が反対となる）ように設けられてもよい。 Further, the plurality of interior materials 30 stacked in the multilayer portion 3A of the cushioning portions 3 and 3'may be set so that the predetermined directions are different from each other. For example, as shown in FIG. 10, the two interior materials 30 stacked in the multilayer portion 3A are inclined in a predetermined direction with respect to the width direction of the packaging bag, and the inclination directions are opposite to each other (inclination with respect to the width direction). It may be provided so that the positive and negative of the angle are opposite to each other).

所定方向が互いに異なる向きに設定された複数枚の内装材３０で構成される多層部３Ａも、所定方向が包装袋の長さ方向に交差していれば、長さ方向に伸長可能である。したがって、このような多層部３Ａを有する緩衝部も、上記の実施形態と同様に懸架された場合には、開口９から包装袋に入れられた物品の重量によって長さ方向に伸長可能である。 The multilayer portion 3A composed of a plurality of interior materials 30 whose predetermined directions are set to be different from each other can also be extended in the length direction as long as the predetermined directions intersect the length direction of the packaging bag. Therefore, the cushioning portion having such a multilayer portion 3A can also be extended in the length direction from the opening 9 by the weight of the article placed in the packaging bag when suspended in the same manner as in the above embodiment.

内装材３０の所定方向が互いに異なる向きに設定された多層部３Ａでは、各々の内装材３０が伸長した場合に切れ込み部３１の周囲が様々な方向に立ち上がるため、厚みをより適切に確保できる。これにより緩衝性が高まるため、包装袋の信頼性を更に高められる。
なお、多層部３Ａでは、三枚以上の内装材３０が厚み方向に重ねられてもよい。内フラップ５についても緩衝部３と同様であり、内フラップ５は交差方向に予め伸長した状態で設けられてもよいし、複数の内フラップ５で所定方向が互いに異なる向きに設定されてもよいし、三つ以上の内フラップ５が包装袋に設けられてもよい。 In the multilayer portion 3A in which the predetermined directions of the interior material 30 are set to be different from each other, the circumference of the notch portion 31 rises in various directions when each interior material 30 is extended, so that the thickness can be more appropriately secured. As a result, the cushioning property is enhanced, so that the reliability of the packaging bag can be further enhanced.
In the multilayer portion 3A, three or more interior materials 30 may be stacked in the thickness direction. The inner flap 5 is the same as the shock absorber 3, and the inner flap 5 may be provided in a state of being extended in advance in the crossing direction, or the plurality of inner flaps 5 may be set in different predetermined directions. However, three or more inner flaps 5 may be provided in the packaging bag.

内袋２０に対する緩衝部３の取付手法は、接着剤や粘着剤を用いた貼付に限定されない。また、外袋１０及び内装材３に対する内袋２０の各貼付位置も上記の位置に限定されない。内袋２０は、厚み方向視において、外袋１０に対する貼付位置と緩衝部３に対する貼付位置とが重なっていてもよい。
内袋２０は、外袋１０に固定されていなくてもよい。換言すれば、内袋２０は、外袋１０から離脱自在に設けられてもよい。内袋２０が外袋１０に固定されていない場合には、外袋１０と内袋２０との間で力の伝達が抑制されるとともに応力集中が生じにくくなるため、内袋２０と緩衝部３との取付部分に応力集中が生じたとしても、外袋１０の破損をより確実に抑えられる。よって、包装袋の信頼性を更に高められる。 The method of attaching the cushioning portion 3 to the inner bag 20 is not limited to the attachment using an adhesive or an adhesive. Further, the sticking position of the inner bag 20 with respect to the outer bag 10 and the interior material 3 is not limited to the above position. In the thickness direction of the inner bag 20, the attachment position with respect to the outer bag 10 and the attachment position with respect to the cushioning portion 3 may overlap.
The inner bag 20 does not have to be fixed to the outer bag 10. In other words, the inner bag 20 may be provided so as to be detachable from the outer bag 10. When the inner bag 20 is not fixed to the outer bag 10, the transmission of force between the outer bag 10 and the inner bag 20 is suppressed and stress concentration is less likely to occur. Therefore, the inner bag 20 and the cushioning portion 3 Even if stress concentration occurs in the mounting portion of the outer bag 10, damage to the outer bag 10 can be suppressed more reliably. Therefore, the reliability of the packaging bag can be further enhanced.

なお、図示は省略するが、本体袋２は、第一面部１１，２１の上端縁部１３，２３の少なくとも一方と、第二面部１２，２２の上端縁部１４，２４の少なくとも一方とに持ち手を設けて、手提げ紙袋とすることもできる。
外袋１０、内袋２０及び緩衝部３（内装材３０）に関し、上記の実施形態で挙げた貼付力の関係は一例である。
本体袋２は一重構造であってもよい。また、外フラップ４及び内フラップ５は、一方又は両方が省略されてもよい。 Although not shown, the main body bag 2 is provided on at least one of the upper end edges 13 and 23 of the first surface portions 11 and 21 and at least one of the upper end edges 14 and 24 of the second surface portions 12 and 22. It can also be used as a handbag by providing a handle.
With respect to the outer bag 10, the inner bag 20, and the cushioning portion 3 (interior material 30), the relationship of the sticking force mentioned in the above embodiment is an example.
The main body bag 2 may have a single structure. Further, one or both of the outer flap 4 and the inner flap 5 may be omitted.
