Description
【０００１】[0001]
本考案は、角底プラスチックフイルム製包装袋に関する。 The present invention relates to a rectangular bottom plastic film packaging bag.
【０００２】[0002]
従来より、プラスチックフイルム製包装袋であって、側縁を融着して角底構造 を有し、手提部がある手提袋は、広く製造されていた。 これらの袋では、図７で示すように角底構造によって幅の広い直方体形状の品 物Ｘを収納しようとした場合に、底部の長方形にぴったりと一致する品物をプラ スチックフイルム製包装袋に入れようとすると、薄い軟質フイルムのため袋の開 口部のフイルムに直方体の４箇所の尖った角Ｋが引っ掛かり挿入するのが困難と なる。すなわち、包装袋の袋体部を直方体形状にしながら、品物を正確に垂直に 維持しながら、挿入するという面倒な操作になる。 例えば、弁当又は寿司などを昼食時の混雑する販売において、収納に手間取る ことはこれら弁当等の売上に密接に影響する重要な問題となる。 また、収納する品物より十分に余裕のある大きい寸法にすると、少し角底を大 きくするだけで、袋フイルムに大きな皺が生じて、品物を入れて吊り下げたとき にぶかぶかの包装体となり体裁が著しく悪くなる。 2. Description of the Related Art Conventionally, a handbag bag made of a plastic film, which has a corner bottom structure in which side edges are fused and has a handbag portion, has been widely manufactured. In these bags, if you want to store a wide rectangular parallelepiped-shaped product X with a square bottom structure as shown in FIG. 7, put the product that exactly matches the bottom rectangle into the plastic film packaging bag. In this case, the thin soft film makes it difficult to insert the four sharp corners K of the rectangular parallelepiped into the film at the opening of the bag. That is, it is a troublesome operation to insert the article while keeping the bag body portion of the packaging bag in a rectangular parallelepiped shape and maintaining the article accurately vertically. For example, in the case of packed lunches or sushi, which is crowded at lunchtime, it is an important problem that the time and effort required to store the bentoes affect the sales of these bento boxes. In addition, if the size of the bag is large enough to accommodate the items to be stored, a slight wrinkle will be created on the bag film, and a large wrinkle will be created on the bag film. Becomes significantly worse.

本考案は、角底の寸法を収納する品物の寸法に合わせたときにおいても、品物 を収納するのが容易な包装袋を提供することを目的とするものである。 It is an object of the present invention to provide a packaging bag that can easily store an item even when the size of the corner bottom is adjusted to the size of the item to be stored.
【０００４】[0004]
本考案者は、前記の角底の寸法を収納物の寸法に合わせて品物を入れ易くする には、図７の開口部の周縁Ｌの長さを長くすることが必須であり、そのために、 周縁に凹状の打ち欠きを設けると、角底の寸法はそのままで、開口周縁の長さが 増加して品物を挿入し易くなることを見出した。すなわち、最初に開口部縁に直 方体の品物が入ると後は、手提部をもって吊り下げると円滑に角底に直方体の角 が収まる。 そして、その凹状打ち欠きの位置を、折り畳み状態で袋体側縁部から手提部に かけて凹状に打ち欠きを設けると左右側縁融着線の両側に２対の打ち欠きが形成 されて、このような位置に打ち欠きを合計４個設けたときが、打ち欠き部分に重 力がかからないので袋が打ち欠き部分から裂ける恐れがないことを見出した。 本考案は、この知見に基づき完成されたものである。 すなわち、本考案は、次の(１)項、(２)項、(３)項、(４)項及び(５)項の考案 よりなる。 （１）プラスチックフイルムからなる包装袋であって、折り畳み状態において、 袋体底部は内部にガゼット折りの折り込み部を断面Ｗ字型に設けて４重構造を形 成してなり、左右側縁部は、底部の４重構造フイルムから側部の２重構造フイル ムにかけて融着して固定し、該折り込み部の４重構造を形成する２対の２重フイ ルム部の総ての左右隅合計４箇所に側縁から底部にかけて傾斜する約４５度の角 底傾斜融着線を設けることにより角底構造とし、袋体部の上部に袋体の上縁フイ ルムから延設してその中央部に指孔を明けた手提部を設けた包装袋であって、手 提部と側縁部との間に凹状の打ち欠き部を設けたことを特徴とする包装袋。 （２）プラスチックフイルムからなる包装袋であって、折り畳み状態において、 袋体底部は内部にガゼット折りの折り込み部を断面Ｗ字型に設けて４重構造を形 成してなり、左右側縁部は、底部の４重構造フイルムから側部の２重構造フイル ムにかけて融着して固定し、該折り込み部の４重構造を形成する２対の２重フイ ルム部の総ての左右隅合計４箇所に側縁から底部にかけて傾斜する約４５度の角 底傾斜融着線を設けることにより角底構造とし、袋体部の上部に袋体の上縁フイ ルムから内側にフイルムを折り返して２対の２重構造を形成し、各２重構造の左 右隅を上縁から約４５度の角度で左右に広がる合計４個の手提傾斜融着線で融着 し、手提傾斜融着線の間の２重構造の上縁折り目を切り離して２対の２重フイル ムの内側フイルムを外側フイルムから分離して、該内側フイルムを手提部フイル ムテープとして形成した包装袋であって、手提傾斜融着線と側縁部との間に凹状 の打ち欠き部を設けたことを特徴とする包装袋。 （３）凹部が袋体を折り畳んだ状態で側縁の近くから中央部方向に、幅１０〜６ ０mmで、開口縁から５〜４０mmの深さの打ち欠きである(１)項又は(２)項記載の 包装袋。 （４）角底傾斜融着線から２〜１０mm離れた外側の平行線上でフイルムを切除し た(１)項、(２)項又は(３)項記載の包装袋。 （５）手提傾斜融着線から２〜１０mm離れた外側の平行線上でフイルムを切除し た(２)項記載の包装袋。 本考案は、手提部の構造が１重フイルムか２重フイルムかによって、態様が上 記(１)項及び(２)項の２種あるが、その凹状打ち欠き部によって、品物を挿入し 易くする技術的思想は同一である。 本考案の凹部の打ち欠きは、袋体の大きさ形状に応じて適宜決定されるが、折 り畳んだ状態で袋体側縁の上部のすぐ近くから袋体中央方向に、幅１０〜６０mm で、かつ、開口縁の縁から下方に５〜４０mmの深さで設ける(３)項の態様が望ま しい。 凹部の深さが小さいと開口縁の長さが伸びる距離が小さくなり本考案の効果が なくなり、大きすぎると開口縁の強度が弱くなる。また、凹部の幅が狭いと強度 が低下し、長すぎると手差部の幅が狭くなる。 The present inventor must elongate the length of the peripheral edge L of the opening shown in FIG. 7 in order to make it easier to put an item in such a manner that the size of the corner bottom matches the size of the stored item. It has been found that if a concave notch is provided on the peripheral edge, the size of the corner bottom remains the same and the length of the peripheral edge of the opening increases to facilitate insertion of the product. That is, when a rectangular parallelepiped item first enters the edge of the opening, the rectangular corner of the rectangular parallelepiped can be smoothly set in the corner bottom by hanging it with the handhold. Then, when the recessed notch is folded and the recessed notch is provided from the bag side edge portion to the handbag portion, two pairs of notch are formed on both sides of the left and right side edge fusion line. We found that when a total of four notches were provided at such positions, the bag was not torn from the notches because no weight was applied to the notches. The present invention has been completed based on this finding. That is, the present invention comprises the following items (1), (2), (3), (4) and (5). (1) A packaging bag made of a plastic film, and in the folded state, the bottom of the bag body has a fold-in portion for gusset folding in a W-shaped cross section to form a quadruple structure. Is the total of all the right and left corners of the two pairs of double film parts that form the quadruple structure of the folded part by fusion-bonding and fixing from the bottom quadruple structure film to the side double structure film. A corner bottom structure is created by providing 45-degree angled bottom fusion welding lines that incline from the side edge to the bottom at four locations, and extend from the top edge film of the bag at the upper part of the bag body and the center part What is claimed is: 1. A packaging bag having a handbag portion having a finger hole formed in the front portion, wherein a concave notch is provided between the handbag portion and a side edge portion. (2) A packaging bag made of a plastic film, and in a folded state, the bottom of the bag body has a fold-in portion for gusset fold in a W-shaped cross section to form a quadruple structure. Is the total of all the right and left corners of the two pairs of double film parts that form the quadruple structure of the folded part by fusion-bonding and fixing from the bottom quadruple structure film to the side double structure film. A square bottom structure is created by providing 45-degree angled bottom fusion welding lines that incline from the side edge to the bottom at four locations, and the film is folded back from the top edge film of the bag to the inside of the bag at the upper part of the bag body. A pair of double structures are formed, and the left and right corners of each double structure are fused with a total of four hand-held slant fusion lines that spread to the left and right at an angle of about 45 degrees from the upper edge. The upper edge fold of the double structure between them is cut off, and the inner film of the two pairs of double films is separated. A packaging bag in which the inner film is separated from the outer film, and the inner film is formed as a film tape for the handhold portion, wherein a concave notch is provided between the handheld slant fusion line and the side edge portion. And a packaging bag. (3) The recess is a notch having a width of 10 to 60 mm and a depth of 5 to 40 mm from the opening edge from the vicinity of the side edge toward the center portion in a state where the bag body is folded (1) or (2). ) Described in the packaging bag. (4) The packaging bag according to item (1), (2), or (3), wherein the film is cut on parallel outer lines 2 to 10 mm away from the angled bottom fusion line. (5) The packaging bag according to the item (2), in which the film is cut on a parallel outer line 2 to 10 mm away from the hand-held slant fusion line. The present invention has two modes, (1) and (2) above, depending on whether the structure of the handbag is a single film or a double film. The concave notch makes it easier to insert an item. The technical idea to do is the same. The notch of the concave portion of the present invention is appropriately determined according to the size and shape of the bag body, but in the folded state, the width is 10 to 60 mm from near the upper part of the side edge of the bag body toward the center of the bag body. Further, it is desirable that the embodiment of the item (3) is provided below the edge of the opening at a depth of 5 to 40 mm. If the depth of the recess is small, the length by which the length of the opening edge extends will be small, and the effect of the present invention will be lost, and if it is too large, the strength of the opening edge will be weakened. Further, if the width of the concave portion is narrow, the strength is lowered, and if it is too long, the width of the manual portion is narrowed.
【０００５】[0005]
本考案を図面によって説明する。 図１及び図２は、プラスチックフイルムを図２の断面図（簡明のために薄いプ ラスチックフイルムの厚さは１本の線で表現してある）のように底部３のＷ字型 のガゼット折りして、底部のＷ字型４重構造を形成する一対の２重構造６、７の 両隅を４個のヒートシールＮ、Ｎ'及びＲ、Ｒ'（Ｎ'及びＲ'は図１の裏面にあっ て見えない。これらはそれぞれＲ'及びＮと重なっている）によって、約４５度 の傾斜で側縁の中折り目１１の高さＨから２重構造６、７の折り目１２、１３に かけて融着し公知の角底構造を形成して、側縁は熔断によって、側縁融着Ｌ、Ｍ を形成して、角底袋体部分を設けている。そして、袋体部のフイルム１及び２か らそれぞれ手提部フイルム４、５が上方に延設されていて、その手提部フイルム ４及び５の中央部に吊り下げるための指孔１０が設けてある。 図１の折り畳み状態で、側縁融着Ｌ、Ｍの上端Ｐ、Ｓからそれぞれ下方に凹状 にへこみ、次いで上方に上がる凹状曲線に沿って、２重のフイルムを同時に打ち 欠いて、本考案の特徴である打ち欠き凹部８が左右側部の開口部縁上に設けてあ る。 この打ち欠き凹部８があるために、側縁融着Ｍを中心にフイルムを展開すると 、図３のように、ＡＳ間及びＳＢ間に凹部分が２箇所に形成される。 その結果ＡＢ間の開口周縁の長さが長くなる分だけ品物を収納し易くなる。 また、この包装袋を吊り下げたときに、この凹部８に力がかかってもこの凹部 分の先端が曲線的な凹状であるので緩衝作用を果し、フイルムが裂けるのを防止 する。 このような凹部分の先端を側縁融着Ｍの真上に設けた場合は二つの手提部から 力がかかるので、凹部分から裂けるおそれがある。 次に、図４及び図５の包装袋は、図１及び図２の手提部４、５がさらに延設さ れて先端１４、１５を内側に折り返されて２重構造となり、その左右隅に約４５ 度の傾斜の融着線Ｃ、Ｄでフイルム４と１４及び５と１５をヒートシールにより 融着して、該ヒートシール融着線から５mm程度離れた平行線Ｔ上で直角三角形部 分を切り離した。このように、傾斜融着線を熔断で行わないで、ヒートシールと その外側の平行線Ｔ上の切断することによって、熔断よりも強度が大きい手提に することができる。 次に４、５の上縁折り目を融着線Ｃ及びＤの中央部Ｅで打ち欠いてフイルム４ と１４及び５と１５を切り離して、手提テープとして、フイルム１４及びフイル ム１５の内側から指を打ち欠きに差し入れて、フイルム１４及びフイルム１５を 形成し、図６のようにフイルム１４を及び１５を持って吊り下げることができる 。 この図４の包装袋も、本考案の特徴である凹状打ち欠き凹部８が側縁の上端Ｐ 及びＳから融着線Ｃ及びＤにかけて設けてある。 この場合の凹状打ち欠き８の作用効果は図１と同様である。 本考案は、折り目１１の高さＨの２倍の寸法が角底の横幅となり、図１及び図 ２の横幅の長さＦから２×Ｈの長さを差し引いた（Ｆ−２Ｈ）が、角底の縦の長 さとなる。本考案の袋により弁当等の直方体を収納する場合、正方形の角底では 、（Ｆ−２Ｈ）＝２Ｈとなる。本考案の収納すべき直方体は、縦長の場合が多く 、実際には、その結果、（Ｆ−２Ｈ）は２Ｈの１〜３倍程度となり、その場合は 、ＦはＨの８倍になる。従って、本考案の寸法Ｆは、Ｈの４〜８倍好ましくは、 ５〜７倍となる。 本考案は、図４の平面図の袋から、袋体側縁を短くして、手提部を長くした態 様の図８の平面図の袋にすることができる。 このように袋体側縁を低くする態様は、図１の袋にも同様に適用することがで きる。 また、図９の袋のように、図４の角底融着線の外側を節棚により切除したもの も、商品の収納が容易になるので好ましい。すなわち、図４のように切除しない 袋の場合よりも角底が広がり易く、結果として、ぴったりとした寸法でも商品を 挿入し易くなる。この場合も、角底を通常の熔断工程にしないで、一旦融着して から、その角底融着線に平行線Ｔ上で切断しているので、角底の強度が飛躍的に 増大する。このような角底の傾斜融着線の外側の平行線Ｔ上の切断は、図１の包 装袋にも適用することができる。 The present invention will be described with reference to the drawings. 1 and 2 show a plastic film with a W-shaped gusset fold at the bottom 3 as in the cross-sectional view of FIG. 2 (thickness of thin plastic film is represented by a single line for clarity). Then, four heat seals N, N'and R, R '(N' and R'are shown in FIG. 1) are formed at both corners of the pair of double structures 6 and 7 forming the bottom W-shaped quadruple structure. It is on the back side and is not visible. These overlap with R'and N respectively), so that from the height H of the middle fold 11 of the side edge to the folds 12 and 13 of the double structures 6 and 7 at an inclination of about 45 degrees. Then, the side edges are fused to form a known square bottom structure, and the side edges are fused to form side edge fusions L and M to provide a square bottom bag portion. Then, handbag films 4 and 5 are extended upward from the films 1 and 2 of the bag body, respectively, and a finger hole 10 for hanging the handbag films 4 and 5 is provided at the center thereof. . In the folded state shown in FIG. 1, the side edge fusions L and M are indented downwardly from the upper ends P and S, respectively, and then double upwardly cut along the concave curve, and the double films are simultaneously punched out. A characteristic notch recess 8 is provided on the edge of the opening on the left and right sides. Due to the presence of the notched concave portion 8, when the film is developed around the side edge fusion M, two concave portions are formed between AS and SB as shown in FIG. As a result, the length of the peripheral edge of the opening between AB becomes longer, so that it becomes easier to store the product. Further, even when a force is applied to the concave portion 8 when the packaging bag is suspended, the tip of the concave portion has a curved concave shape, which serves as a cushioning function and prevents the film from tearing. When the tip of such a concave portion is provided directly above the side edge fusion M, force is applied from the two hand parts, so there is a risk of tearing from the concave portion. Next, in the packaging bag of FIGS. 4 and 5, the handbags 4 and 5 of FIGS. 1 and 2 are further extended and the tips 14 and 15 are folded back inward to form a double structure. Films 4 and 14 and 5 and 15 are fused by heat sealing at fusion lines C and D inclined at about 45 degrees, and a right-angled triangle portion is formed on a parallel line T separated by about 5 mm from the heat sealing fusion line. Separated. As described above, by cutting the heat-seal and the parallel lines T on the outer side of the heat-sealing line without melting the inclined fusion-bonding line, it is possible to obtain a handpiece having a higher strength than the fusing. Next, the upper edge folds 4 and 5 are punched out at the central portion E of the fusion lines C and D to separate the films 4 and 14 and 5 and 15, and a finger tape is used from the inside of the films 14 and 15 as a handy tape. Can be inserted into the notch to form the film 14 and the film 15, and the film 14 and the film 15 can be hung and held as shown in FIG. The packaging bag shown in FIG. 4 is also provided with the concave notch 8 which is a feature of the present invention from the upper ends P 1 and S 2 of the side edges to the fusion lines C and D. The function and effect of the concave notch 8 in this case are the same as those in FIG. In the present invention, the width of the corner bottom is twice the height H of the fold line 11, and the length F of the width is subtracted from the length F of FIG. 1 and FIG. 2 (F-2H). The vertical length of the corner bottom. When a rectangular parallelepiped such as a bento is stored in the bag of the present invention, (F-2H) = 2H at the square corner bottom. The rectangular parallelepiped to be stored in the present invention is often vertically long, and as a result, (F-2H) is about 1 to 3 times 2H, and in that case, F is 8 times H. Therefore, the dimension F of the present invention is 4 to 8 times H, preferably 5 to 7 times. According to the present invention, the bag shown in the plan view of FIG. 8 can be changed from the bag shown in the plan view of FIG. Such a mode in which the side edge of the bag body is lowered can be similarly applied to the bag of FIG. Also, it is preferable that the outer side of the corner bottom fusion line of FIG. 4 is cut off by a node shelf like the bag of FIG. 9 because the product can be stored easily. That is, as compared with the case where the bag is not cut as shown in FIG. 4, the corner bottom is more easily spread, and as a result, it is easier to insert the product even with a tight size. Also in this case, since the corner bottom is not subjected to the usual fusing process, it is once fused and then cut on the parallel line T to the corner bottom fusion line, so that the strength of the corner bottom is dramatically increased. . The cutting on the parallel line T outside the inclined fusion-bonded line of the square bottom can also be applied to the packaging bag of FIG.

本考案の側縁上部から手提部にかけての凹状曲線に沿った打ち欠き凹部８によ って、袋体角底寸法とほぼ一致した商品を素早く収納でき、しかも、側縁融着線 の両側に凹部が二つあるので、凹部によって、開口部周縁が裂け易くなることは ない。 The notched concave portion 8 along the concave curve from the upper side edge to the handbag of the present invention allows quick storage of products having a bag bottom corner size substantially equal to each other, and on both sides of the side edge fusion line. Since there are two concave portions, the concave portions do not easily tear the peripheral edge of the opening.
