Description

本件は、物品を包装する袋およびこの包装袋を用いた物品の収納方法に関する。 This case relates to a bag for packaging articles and a method for storing articles using this packaging bag.

包装資材として、複数の空気室が設けられたエアクッションや発泡性のフォームクッション，片面段ボールなどの厚み方向に変形するシート状の緩衝材が用いられている。このような緩衝材で包装された物品は、輸送時や保管時に、包装袋に入れられることがある。
そこで、緩衝材を有する包装袋が開発されている。たとえば、複数の空気室が設けられた一対のシートの端縁どうしが封止された包装袋が提案されている（特許文献１参照）。 As packaging materials, sheet-like cushioning materials that deform in the thickness direction, such as air cushions with multiple air chambers, foam cushions, and single-sided corrugated cardboard, are used. Articles packaged with such cushioning materials are sometimes placed in packaging bags during transportation or storage.
Therefore, packaging bags having a cushioning material have been developed. For example, a packaging bag has been proposed in which the edges of a pair of sheets each having a plurality of air chambers are sealed (see Patent Document 1).

環境負荷の観点から、本体袋１とシート状緩衝部２の両方が紙製であることが好ましい。 (sheet-like buffer)
It is preferable that the sheet-like buffer section 2 be made of the same material as the main bag 1 in order to recycle the packaging bag. Further, it is preferable that the sheet-like buffer section 2 is made of a stretchable material.
From the viewpoint of environmental load, it is preferable that both the main body bag 1 and the sheet-like buffer section 2 are made of paper.

図１に示すように、矩形状のシート状緩衝部２（緩衝シート材）の１つの端部には、本体袋１との貼付領域３ｂ（シート状緩衝部側接着部）を有し、貼付領域３ｂは本体袋１の貼付領域３ａ（本体袋側接着部）と接合してシート状緩衝部２を本体袋１に接着（固定）する。 As shown in FIG. 1, one end of the rectangular sheet-like buffer section 2 (buffer sheet material) has an attachment area 3b (adhering section on the sheet-like buffer section side) with the main body bag 1. The region 3b is joined to the attachment region 3a (main body bag side adhesive portion) of the main body bag 1 to adhere (fix) the sheet-like buffer portion 2 to the main body bag 1.

シート状緩衝部２は、貼付領域３ｂから対向する端部４（シート状緩衝部巻き付け端部）へ向かう方向（伸張方向）に伸縮性を有すること（伸張可能であること）が好ましい。伸縮性を有するシート状緩衝部２としては、軟質樹脂シート、折り畳まれたシート、所定 の延在方向（伸張方向に交差する方向）に延びる複数の切れ込み部が千鳥状に設けられた シート等が好ましい。 It is preferable that the sheet-like buffering section 2 has elasticity (stretchability) in the direction (stretching direction) from the pasting region 3b toward the opposing end 4 (the wrapping end of the sheet-like buffering section). As the elastic sheet-like buffer section 2, a soft resin sheet, a folded sheet, a sheet with a plurality of notches extending in a predetermined extension direction (a direction intersecting the extension direction) in a staggered manner, etc. can be used. preferable.

これらシートの中でも特に複数の切れ込み部が千鳥状に設けられたシートが好ましい。 Among these sheets, a sheet in which a plurality of notches are provided in a staggered manner is particularly preferred.

図１５を参照して、未伸張状態のシート状緩衝部２を説明する。
シート状緩衝部２には、多数の切れ込み部２３ａが切り込まれて形成されている。これらの切れ込み部２３ａは、シート状緩衝部２の少なくとも一部に設けられている。
切れ込み部２３ａは、懸架方向（ここでは上下方向）に対して直交する方向（以下「幅 方向」という）に延びている。 Referring to FIG. 15, the sheet-like buffer section 2 in an unstretched state will be described.
The sheet-like buffer section 2 is formed with a large number of notches 23a. These cut portions 23 a are provided in at least a portion of the sheet-like buffer portion 2 .
The cut portion 23a extends in a direction (hereinafter referred to as the "width direction") orthogonal to the suspension direction (in this case, the vertical direction).

この切れ込み部２３ａは、幅方向に沿って断続的に並んで設けられている。すなわち、幅方向に隣接する切れ込み部２３ａどうしの間には、切り込まれていない非切れ込み部２３ｂが設けられている。
切れ込み部２３ａの寸法を「Ｌ1」とし、非切れ込み部２３ｂの寸法を「Ｌ2」とすれば、不等式１「Ｌ1＞Ｌ2」が満たされる。 The notches 23a are arranged intermittently in the width direction. That is, a non-cut portion 23b that is not cut is provided between the cut portions 23a that are adjacent to each other in the width direction.
If the dimension of the cut portion 23a is “L 1 ” and the dimension of the non-cut portion 23b is “L 2 ”, inequality 1 “L 1 >L 2 ” is satisfied.

ここで、切れ込み部２３ａおよび非切れ込み部２３ｂが幅方向に沿って交互に並んで設けられた一行の配向を第一パターンＰ1とする。また、第一パターンＰ1の切れ込み部２３ａおよび非切れ込み部２３ｂとは半ピッチずらされて配置された切れ込み部２３ａ′および非切れ込み部２３ｂ′が幅方向に沿って交互に並んで設けられた他行の配向を第二パターンＰ2とする。これらの第一パターンＰ1および第二パターンＰ2は、懸架方向に沿って交互に並んで設けられる。 Here, the orientation of one row in which the cut portions 23a and the non-cut portions 23b are arranged alternately along the width direction is defined as a first pattern P1 . Further, cut portions 23a' and non-cut portions 23b', which are arranged to be shifted by half a pitch from the cut portions 23a and non-cut portions 23b of the first pattern P1 , are arranged alternately along the width direction. The row orientation is a second pattern P2 . These first patterns P 1 and second patterns P 2 are arranged alternately along the suspension direction.

詳細に言えば、第一パターンＰ1における切れ込み部２３ａの幅方向中心Ｃaと第二パターンＰ2における非切れ込み部２３ｂ′の幅方向中心Ｃb′とが懸架方向に沿って並んで配置される。同様に、第一パターンＰ1における非切れ込み部２３ｂの幅方向中心Ｃbと第二パターンＰ2における切れ込み部２３ａ′の幅方向中心Ｃa′とが懸架方向に沿って並んで配置される。 Specifically, the width direction center C a of the cut portion 23a in the first pattern P 1 and the width direction center C b′ of the non-cut portion 23 b′ in the second pattern P 2 are arranged side by side along the suspension direction. Ru. Similarly, the widthwise center C b of the non-cut portion 23b in the first pattern P 1 and the widthwise center C a′ of the cut portion 23a' in the second pattern P 2 are arranged side by side along the suspension direction.

このような切れ込み部２３ａ，２３ａ′および非切れ込み部２３ｂ，２３ｂ′が設けられた本体部２３を有する緩衝部２０は、切れ込み部２３ａ，２３ａ′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２３ａ，２３ａ′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、シート状緩衝部２が製造される。 The buffer section 20 has a main body section 23 provided with such cut portions 23a, 23a' and non-cut portions 23b, 23b'. It is manufactured by cutting an uncut sheet material while rotating it using a rotary die cutter. Alternatively, the sheet-like buffer section 2 is manufactured by cutting the uncut sheet material while pressing it using a flat plate die cutter provided with a blade section having a shape corresponding to the notches 23a and 23a'.

第一パターンＰ1の切れ込み部２３ａに対して懸架方向のうち一方（図１６では上方）のシート片は、第二パターンＰ2の切れ込み部２３ａ′および非切れ込み部２３ｂ′に対する位置によって第一片部３１，第二片部３２および第三片部３３に大別される。
第一片部３１は、第一パターンＰ1の切れ込み部２３ａのうち幅方向一方（図１６では左方）と第二パターンＰ2の切れ込み部２３ａ′のうち幅方向他方（図１６では右方）とで挟まれる部位である。第二片部３２は、第一パターンＰ1の切れ込み部２３ａの幅方向中央と第二パターンＰ2の非切れ込み部２３ｂ′とで挟まれる部位である。第三片部３３は、第一パターンＰ1の切れ込み部２３ａのうち幅方向他方と第二パターンＰ2の切れ込み部２３ａ′のうち幅方向一方とで挟まれる部位である。 The sheet piece on one side (upper side in FIG. 16) of the suspension direction with respect to the notch 23a of the first pattern P1 is determined by the position of the first sheet piece with respect to the notch 23a' and the non-notch part 23b' of the second pattern P2 . It is roughly divided into a portion 31, a second piece portion 32, and a third piece portion 33.
The first piece portion 31 has one side in the width direction (the left side in FIG. 16 ) of the notches 23a of the first pattern P1 and the other side in the width direction (the right side in FIG. 16) of the notches 23a' of the second pattern P2. ) is the part sandwiched between. The second piece portion 32 is a portion sandwiched between the widthwise center of the cut portion 23a of the first pattern P1 and the non-cut portion 23b ' of the second pattern P2. The third piece 33 is a portion sandwiched between the other of the notches 23a of the first pattern P1 in the width direction and one of the notches 23a' of the second pattern P2 in the width direction.

また、第一パターンＰ1の切れ込み部２３ａに対して懸架方向のうち他方のシート片は、上記の片部３１，３２，３３と同様に、第四片部３４，第五片部３５および第六片部３６に大別される。
第四片部３４は、第一パターンＰ1の切れ込み部２３ａのうち幅方向一方と第二パターンＰ2の切れ込み部２３ａ′の幅方向他方とで挟まれる。第五片部３５は、第一パターンＰ1の切れ込み部２３ａの幅方向中央と第二パターンＰ2の非切れ込み部２３ａ′とで挟まれる。第六片部３６は、第一パターンＰ1の切れ込み部２３ａのうち幅方向他方と第二パターンＰ2の切れ込み部２３ａ′のうち幅方向一方とで挟まれる。 Further, the other sheet piece in the suspension direction with respect to the notch 23a of the first pattern P1 is the fourth piece 34, the fifth piece 35, and the It is roughly divided into six pieces 36.
The fourth piece 34 is sandwiched between one of the notches 23a of the first pattern P 1 in the width direction and the other of the notches 23a' of the second pattern P 2 in the width direction. The fifth piece portion 35 is sandwiched between the widthwise center of the cut portion 23a of the first pattern P 1 and the non-cut portion 23a′ of the second pattern P 2 . The sixth piece 36 is sandwiched between the other of the notches 23a of the first pattern P 1 in the width direction and one of the notches 23a' of the second pattern P 2 in the width direction.

つづいて、図１６および図１７を参照して、伸張状態のシート状緩衝部２を説明する。
図１６に示すように、伸張状態のシート状緩衝部２は、非伸張状態のシート状緩衝部２と比較して、懸架方向（図１６の上下方向）に伸びている。このときのシート状緩衝部２では、非伸張状態におけるシート状緩衝部２の厚み方向へ片部３１～３６が立ち上がり、立ち上がった片部３１～３６によって立体状の緩衝セル４０が形成される。言い換えれば、一つの切れ込み部２３ａに対して周囲に配置された片部３１～３６が立ち上がることで、一つの緩衝セル４０が出現する。 Next, the sheet-like buffer section 2 in the expanded state will be described with reference to FIGS. 16 and 17.
As shown in FIG. 16, the sheet-like buffer section 2 in the stretched state extends in the suspension direction (vertical direction in FIG. 16) compared to the sheet-like buffer section 2 in the non-stretched state. In the sheet-like buffering section 2 at this time, the pieces 31 to 36 stand up in the thickness direction of the sheet-like buffering section 2 in the non-stretched state, and the three-dimensional buffer cells 40 are formed by the rising pieces 31 to 36. In other words, one buffer cell 40 appears when the pieces 31 to 36 arranged around one notch 23a stand up.

詳細に言えば、図１６に示すように、第一片部３１に対応する第一壁部４１，第二片部３２に対応する第二壁部４２，第三片部３３に対応する第三壁部４３，第四片部３４に対応する第四壁部４４，第五片部３５に対応する第五壁部４５および第六片部３６に対応する第六壁部４６が、六角筒の各側壁をなすように緩衝セル４０において立設される。 Specifically, as shown in FIG. The wall 43, the fourth wall 44 corresponding to the fourth piece 34, the fifth wall 45 corresponding to the fifth piece 35, and the sixth wall 46 corresponding to the sixth piece 36 are of a hexagonal tube. The buffer cells 40 are erected to form each side wall.

なお、シート状緩衝部２が破損しない範囲で幾何学的に最も伸張した状態（以下「最大伸張状態」という）では、第一壁部４１および第四壁部４４が同一平面に沿うとともに、第三壁部４３および第六壁部４６が他の同一平面に沿って第一壁部４１および第四壁部４４と対向する。そのため、最大伸張状態の緩衝セル４０では、四角筒の各側壁をなすように壁部４１～４６が立設される。 Note that in the state where the sheet-like buffer section 2 is geometrically stretched the most without being damaged (hereinafter referred to as the "maximum stretch state"), the first wall section 41 and the fourth wall section 44 lie along the same plane, and the fourth wall section 44 extends along the same plane. The third wall portion 43 and the sixth wall portion 46 face the first wall portion 41 and the fourth wall portion 44 along the other same plane. Therefore, in the buffer cell 40 in the maximum expanded state, the wall portions 41 to 46 are erected to form each side wall of the square tube.

シート状緩衝部２を物品に巻き付けたとき、立体状の緩衝セル４０によって形成されるシート状緩衝部２の凹凸同士が噛み合わさりシート状緩衝部２が巻き戻されることを防止し、物品を固定し衝撃から保護する効果を高めることができる。 When the sheet-like buffer section 2 is wrapped around an article, the unevenness of the sheet-like buffer section 2 formed by the three-dimensional buffer cells 40 engage with each other, preventing the sheet-like buffer section 2 from being rewound and fixing the article. This can increase the effect of protecting against impact.

［２．包装袋の使用手順］
つぎに、包装袋の使用方法（包装袋を用いた物品の収納方法）を説明する。
図２および図３に示すように、はじめにシート状緩衝部２を広げた上に、内包する物品５を置く。
次に、図４および図５に示すように、物品５にシート状緩衝部２をたとえば一周以上巻きつけていく。このときシート状緩衝部２を適度に伸張した状態で巻き付けることが好ましい。
図６および図７に示すように、（シート状緩衝部２の物品５に巻き付けていない部分の物品５の懸架方向の最大伸張長さ）－（シート状緩衝部２の物品５に巻き付けていない部分の懸架方向の未伸張時長さ）が、物品５を本体袋１に収納したときの本体袋１の底から物品５までの長さ以上とすることが好ましい。
最後に図８および図９に示すように、フラップ１ａを閉じて物品５の収納を完了する。このようにして包装袋の内部（包装袋内部）へ物品５を収容する。 [2. Instructions for using packaging bags]
Next, a method of using the packaging bag (a method of storing articles using the packaging bag) will be explained.
As shown in FIGS. 2 and 3, first, the sheet-like buffer section 2 is spread out, and then the article 5 to be contained therein is placed.
Next, as shown in FIGS. 4 and 5, the sheet-like buffer section 2 is wrapped around the article 5, for example, once or more. At this time, it is preferable to wrap the sheet-like buffer section 2 in a moderately stretched state.
As shown in FIGS. 6 and 7, (maximum extension length in the suspension direction of the article 5 of the part of the sheet-like buffer section 2 that is not wrapped around the article 5) - (maximum extension length in the suspension direction of the section of the sheet-like buffer section 2 that is not wrapped around the article 5) It is preferable that the length (unstretched length of the part in the suspension direction) is equal to or longer than the length from the bottom of the main body bag 1 to the article 5 when the article 5 is stored in the main body bag 1.
Finally, as shown in FIGS. 8 and 9, the flap 1a is closed to complete storage of the article 5. In this way, the article 5 is accommodated inside the packaging bag (inside the packaging bag).

上記のように巻き付ける方法を採用することによって、包装袋が本体袋の底部を下にして落下したときに、物品５に巻き付いたシート状緩衝部２の物品５に巻き付けていない部分が延びて衝撃を和らげ、物品５を保護することができる。 By adopting the wrapping method as described above, when the packaging bag falls with the bottom of the main bag facing down, the portion of the sheet-like buffer 2 that is not wrapped around the item 5 stretches and causes an impact. can be softened and the article 5 can be protected.
