Description

この発明は、手提げ孔が設けられたラミネートフィルム製の米袋において、袋の前後面を形成する前パネルと後パネルの間に、ポリエチレン製フィルム又は不織布シートからなる補強シートを挟み込むことによって、手提げ孔部における強度を向上させるとともに、手触りを優しくした手提げ孔付き米袋に関する。   The present invention relates to a laminating film rice bag provided with handbag holes, by sandwiching a reinforcing sheet made of a polyethylene film or a non-woven sheet between the front panel and the rear panel forming the front and rear surfaces of the bag, The present invention relates to a rice bag with a handbag hole that improves the strength at the section and makes the feel gentle.

一般的な米袋の材質は、プラスチック製ラミネートフィルムが主流であり、スーパーマーケットや米販売店で購入して持ち帰るために、手提げ用の孔が設けられたものがある。
ラミネートフィルム製で手提げ孔が設けられた米袋の一例として、特許３４８７３１７号の公報に記載されたものが知られている。
特許３４８７３１７号公報 A common material for rice bags is a plastic laminate film, and there are those provided with holes for handbags for purchase at supermarkets and rice stores.
As an example of a rice bag made of a laminate film and provided with a hand hole, one described in Japanese Patent No. 3487317 is known.
Japanese Patent No. 3487317

前記特許３４８７３１７号公報に記載された米袋５１は、ラミネートフィルムからなり、図７に示すように前パネル５２と後パネル５３の一端に把手５４が形成され、口元シール５５と把手シール５６の間に手提げ孔５７が設けられている。この米袋５１は、手提げ孔５７が設けられているので手提げして持ち帰ることができる。しかし、この米袋５１の手提げ部は、手提げしたときに５ｋｇ〜１０ｋｇもある米の重量により発生する応力を手指で支えるため図８に示すように手提げ孔５７が変形し、手提げ孔５７の上部周縁における手指の人差し指近辺のＸ部及び小指近辺のＹ部に集中するため、その部分が延びて変形し易く、フィルムに亀裂Ｚが入って裂けやすくなる欠点があった。   The rice bag 51 described in the Japanese Patent No. 3487317 is made of a laminate film, and as shown in FIG. 7, a handle 54 is formed at one end of the front panel 52 and the rear panel 53, and between the mouth seal 55 and the handle seal 56. A hand hole 57 is provided. Since this rice bag 51 is provided with a hand hole 57, it can be handed and taken home. However, the handbag portion of the rice bag 51 is deformed as shown in FIG. 8 to support the stress generated by the weight of rice of 5 kg to 10 kg with the fingers, and the upper peripheral edge of the handbag hole 57 is formed. In this case, there is a defect that the portion extends and deforms easily, and the film is easily cracked due to a crack Z.

また、上記手提げ孔５７周辺のフィルムが延びることを防止するために、図９に示すように手提げ孔５７の周囲を５〜１０ｍｍ幅で熱シールして強化する方法も試みられているが、フィルムが熱シールされるとその熱シール部分５８が硬化するため、重い米袋を手提げして歩くときに熱シール部分５８が手指に直接強く当たり、痛くなることがあった。   Further, in order to prevent the film around the hand hole 57 from extending, an attempt has been made to reinforce the periphery of the hand hole 57 with a width of 5 to 10 mm as shown in FIG. Since the heat-sealed portion 58 is cured when it is heat-sealed, the heat-sealed portion 58 may hit the fingers directly and hurt when walking with a heavy rice bag.

この発明は、上述の課題を解決するためになされたもので、その目的は、米が充填された重い袋を手提げして歩いても、手提げ孔部の変形が少なく強度に優れ、しかも手に優しく痛くならない米袋を提供することにある。   The present invention has been made to solve the above-mentioned problems, and its purpose is to have a small strength of the handbag hole and to have a high strength even when walking with a heavy bag filled with rice. The purpose is to provide rice bags that do not hurt gently.

上記目的を達成するために、米が充填された袋を持ち下げた時に作用する力を一ヶ所又は二ヶ所に集中させず、手提げ部分全体に分散させるための補強シートを袋の前パネルと後パネルの間に挟み込み、補強シートのほぼ全域にわたり熱シールして前パネルと後パネルに一体的に融着させ、かつその補強シートには前パネルと後パネルに設けられた手提げ孔よりも小さく形成された手提げ孔を設けたことを特徴とするものである。
さらに具体的には、
プラスチック製ラミネートフィルムからなり、かつ袋を構成する前パネルと後パネルに共通の第一の手提げ孔が形成された米袋であって、
前パネルと後パネルとの間に、ポリエチレン製フィルム又は不織布シートからなる補強シートが第一の手提げ孔を塞ぐ大きさに切断されて挿入されており、
その補強シートには第一の手提げ孔よりも小さな第二の手提げ孔が形成され、その手提げ孔は第一の手提げ孔の内側に配置され、
第一の手提げ孔の外側において、補強シートのほぼ全域にわたって複数列の直線状あるいは曲線状のシール又は全面にベタシールがが行われることにより補強シートが前パネルと後パネルの間に一体的に融着されていることを特徴とする手提げ孔付米袋である。
また、前パネルと後パネルに形成された第一の手提げ孔の内周の上縁部と、補強シートに形成された第二の手提げ孔の内周の上縁部との距離が５ないし２０ｍｍ程度離れるように第二の手提げ孔が第一の手提げ孔よりも小さく形成されて配置されていることを特徴とする手提げ孔付米袋である。
前パネルと後パネルに形成された第一の手提げ孔の外側において、補強シートのほぼ全域にわたって直線状又は曲線状に形成された複数列のシール線を有する熱シール、あるいは補強シートのほぼ全域にわたってベタシールが行わが行われて補強シートが前パネルと後パネルの間に一体的に融着されていることを特徴とする手提げ孔付米袋である。 In order to achieve the above-mentioned purpose, the reinforcing sheet for distributing the entire hand-carrying part is not concentrated on one or two places when the bag filled with rice is lowered, but the front panel and the rear of the bag. It is sandwiched between the panels, heat-sealed over almost the entire area of the reinforcing sheet, and fused integrally to the front panel and the rear panel, and the reinforcing sheet is formed smaller than the hand holes provided in the front panel and the rear panel It is characterized by providing a hand-made hole.
More specifically,
A rice bag made of a laminated film made of plastic and having a common first hand hole formed in the front panel and the rear panel constituting the bag,
Between the front panel and the rear panel, a reinforcing sheet made of a polyethylene film or non-woven sheet is cut and inserted into a size that closes the first handbag hole,
The reinforcing sheet is formed with a second hand hole smaller than the first hand hole, and the hand hole is disposed inside the first hand hole.
Outside the first hand hole, a plurality of lines of linear or curved seals or a solid seal is applied over the entire surface of the reinforcing sheet, so that the reinforcing sheet is fused integrally between the front panel and the rear panel. It is a rice bag with a handbag hole characterized by being worn.
The distance between the upper edge of the inner periphery of the first hand hole formed in the front panel and the rear panel and the upper edge of the inner periphery of the second hand hole formed in the reinforcing sheet is 5 to 20 mm. A rice bag with a hand hole, wherein the second hand hole is formed so as to be smaller than the first hand hole so as to be separated from each other.
Outside the first hand hole formed in the front panel and the rear panel, a heat seal having a plurality of rows of sealing lines formed linearly or curvedly over almost the entire area of the reinforcing sheet, or over almost the entire area of the reinforcing sheet It is a rice bag with a hand hole, characterized in that solid sealing is performed and the reinforcing sheet is integrally fused between the front panel and the rear panel.

上記の構成とすることにより、米が充填された袋の手提げ孔に手を挿入して持ち下げた時、補強シートの手提げ孔の内周の上縁部は掌と反対側、即ち指先側へＬ字状に折れ曲がって手指に当たることとなる。この時、前パネルと後パネルの手提げ孔の上縁には米の重量による応力は直接作用しないため手提げ孔の内周の上縁部のいずれも手指あるいは掌に強く当たらない。
補強シートが前後のパネルの間に介在することにより、米の重量による応力は補強シートを熱シールした全体に分散し、パネルの手提げ孔の人差し指側と小指側の二ヶ所に集中しない。よって手提げ孔部の破損を防ぐ米袋となる。
補強シートの手提げ孔を前後のパネルの手提げ孔よりも５ｍｍないし２０ｍｍ小さく形成することにより、補強シートが折れ曲がって手の指腹に所定の幅を持って接触することにより手に優しい米袋とすることができる。 With the above configuration, when the hand is inserted into the handbag hole of the bag filled with rice and lifted, the upper edge of the inner periphery of the handbag hole of the reinforcing sheet is on the side opposite to the palm, that is, the fingertip side. It will be bent in an L shape and hit your fingers. At this time, since the stress due to the weight of the rice does not directly act on the upper edge of the handbag hole in the front panel and the rear panel, neither the upper edge of the inner periphery of the handhole hits the finger or palm strongly.
Since the reinforcing sheet is interposed between the front and back panels, the stress due to the weight of the rice is dispersed throughout the heat-sealed reinforcing sheet, and does not concentrate on the index finger side and the little finger side of the handbag hole of the panel. Therefore, it becomes the rice bag which prevents the breakage of the hand hole.
By making the handbag holes of the reinforcing sheet 5mm to 20mm smaller than the handbag holes of the front and rear panels, the reinforcing sheet bends to make it a hand-friendly rice bag by contacting the finger pad with a predetermined width. Can do.

以下、この発明の実施例を図１ないし図５に示す図面に基づいて説明する。 Embodiments of the present invention will be described below with reference to the drawings shown in FIGS.

図１に示す米袋１は２枚のシートが重ね合わされており、前パネル２に米の銘柄、後パネル３に精米所名等々が印刷されている。重ね合わされた前パネル２と後パネル３のそれぞれの上端部の所定位置に、第一の手提げ孔４と手提げ孔５を刃物で打ち抜いて同時加工する。この手提げ孔４、５は従来の手提げ孔よりも若干大きく形成されるものである。   The rice bag 1 shown in FIG. 1 has two sheets superimposed on each other. A rice brand is printed on the front panel 2, a rice mill name is printed on the rear panel 3, and the like. The first hand hole 4 and the hand hole 5 are punched with a blade at predetermined positions on the upper ends of the overlapped front panel 2 and rear panel 3 and processed simultaneously. The hand holes 4 and 5 are formed slightly larger than the conventional hand holes.

前パネル２と後パネル３を一旦上下に分離して空間を作り、その間へ第一の手提げ孔４、５を塞ぐ大きさに切断された補強シート６を挿入して下側に配置されている後パネル３の内面に重ねた後、位置ズレを防ぐための仮止めを行う。仮止めの方法は、熱によるポイントシール、接着等々あまり強度を必要としない手段でよい。補強シート６の材質は、手に直接触れても痛さを感じにくいポリエチレンや不織布からなる。   The front panel 2 and the rear panel 3 are once vertically separated to create a space, and a reinforcing sheet 6 cut to a size for closing the first handbag holes 4 and 5 is inserted between them to be disposed on the lower side. After superimposing on the inner surface of the rear panel 3, temporary fixing is performed to prevent displacement. The temporary fixing method may be a means that does not require much strength, such as point sealing by heat and adhesion. The material of the reinforcing sheet 6 is made of polyethylene or non-woven fabric that does not feel pain even if it is in direct contact with the hand.

手提げ孔４、５が合致するように前パネル２と後パネル３を再び重ね合わせ、続いて前記前パネル２と後パネル３に加工された手提げ孔４、５よりも一回り小さく形成された第二の手提げ孔７を補強シート６に刃物で打ち抜く。この第二の手提げ孔７の上部周縁７ａは第一の手提げ孔４、５の上部周縁４ａ、５ａから所定距離だけ下方へ離れた内側に位置している。補強シート６における手提げ孔７の上部周縁７ａと前後のパネル２、３における手提げ孔４、５の上部周縁４ａ、５ａとの距離Ｘは、５ｍｍから２０ｍｍぐらいが好ましい。
上記距離Ｘが小さいと、袋１が米の重量で変形したときに前後のパネル２、３における手提げ孔４、５の上部周縁４ａ、５ａが手指の腹に直接当たって痛さを感ずるようになる。 The front panel 2 and the rear panel 3 are overlapped again so that the hand holes 4 and 5 are aligned with each other. Subsequently, the first panel 2 is formed to be slightly smaller than the hand holes 4 and 5 formed in the front panel 2 and the rear panel 3. The second hand hole 7 is punched into the reinforcing sheet 6 with a blade. The upper peripheral edge 7a of the second hand-carrying hole 7 is located on the inner side of the first hand-carrying holes 4 and 5 with a predetermined distance downward from the upper peripheral edges 4a and 5a. The distance X between the upper peripheral edge 7a of the hand hole 7 in the reinforcing sheet 6 and the upper peripheral edges 4a and 5a of the hand holes 4 and 5 in the front and rear panels 2 and 3 is preferably about 5 mm to 20 mm.
When the distance X is small, when the bag 1 is deformed by the weight of rice, the upper peripheral edges 4a and 5a of the hand holes 4 and 5 in the front and rear panels 2 and 3 directly hit the belly of the fingers and feel pain. Become.

次に、前パネル２と後パネル３に形成された第一の手提げ孔４，５の外側において、補強シート６のほぼ全域にわたって直線状又は曲線状に形成された複数列のシール線８を有する熱シールを行う。   Next, a plurality of rows of seal lines 8 are formed in a linear or curved shape over almost the entire area of the reinforcing sheet 6 outside the first hand holes 4 and 5 formed in the front panel 2 and the rear panel 3. Perform a heat seal.

前記シール線８は、補強シート６の外形線より内側で、かつ第一の手提げ孔４、５の外側にぴったり形成されるのが望ましいが、距離Ｘが大きければ第一の手提げ孔４、５から第二の手提げ孔７側へ多少はみ出しても良いし、補強シート６の外側へはみ出しても良い。第二の手提げ孔７側へはみ出す場合、米袋を手にぶら下げたときシール線８が
手指に直接当たらないような位置までとすることが必要である。 The seal line 8 is preferably formed on the inner side of the outer shape line of the reinforcing sheet 6 and on the outer side of the first hand-carrying holes 4 and 5, but if the distance X is large, the first hand-carrying holes 4 and 5 are formed. To the second hand-carrying hole 7 side, or may protrude to the outside of the reinforcing sheet 6. When it protrudes to the 2nd handbag hole 7 side, it is necessary to make it the position which the seal line 8 does not touch a finger | toe directly, when a rice bag is hung on a hand.

補強シート６のシールが終わった後、重ね合わされた前パネル２と後パネル３のフィルムの流れ方向の両側縁に直線状の側縁シール９を行い、両側縁を閉塞する。   After the sealing of the reinforcing sheet 6 is finished, straight side edge seals 9 are provided on both side edges of the overlapped front panel 2 and rear panel 3 in the film flow direction to close both side edges.

続いて、フィルムの流れ方向に直角方向に前記手提げ孔４，５，７を挟んで直線状の下口元シール１０と上口元シール１１を行い、袋上部を閉塞する。下口元シール１０と上口元シール１１が行われた袋体は、側縁シール９に沿ってギロチンカッターで一枚ずつカットして単葉の米袋１に仕上げるか、もしくは連続してロール状に巻取る。
単葉の米袋１の場合は、米を充填した後で底シールを行って密封し、ロール状に巻き取られたものでは、米を充填する際にカットして米を充填し、底シールを行って密封する。 Subsequently, a linear lower mouth seal 10 and upper mouth seal 11 are performed across the hand holes 4, 5 and 7 in a direction perpendicular to the film flow direction to close the upper portion of the bag. The bag body in which the lower end seal 10 and the upper end seal 11 are performed is cut one by one with a guillotine cutter along the side edge seal 9 and finished into a single-leaf rice bag 1 or continuously wound into a roll. .
In the case of the single-leaf rice bag 1, the bottom sealing is performed after filling the rice and the bottom is sealed, and in the case of the roll wound up, the rice is cut and filled when the rice is filled, and the bottom sealing is performed. And seal.

米が充填された米袋１において、手提げ孔４、５、７に手指を通してぶら下げると（図５）、補強シート６の手提げ孔７の上部周縁７ａが掌と反対側へほぼＬ字状に折れ曲って、その部分が手指Ｈに当たり、前後のパネル２、３の手提げ孔４、５の上部周縁４ａ、５ａが直接手指Ｈに当たることはない。   In the rice bag 1 filled with rice, when the fingers are suspended through the hand holes 4, 5 and 7 (FIG. 5), the upper peripheral edge 7a of the hand hole 7 of the reinforcing sheet 6 is bent in an almost L shape to the opposite side of the palm. Thus, the portion hits the finger H, and the upper peripheral edges 4 a and 5 a of the hand-holding holes 4 and 5 of the front and rear panels 2 and 3 do not directly hit the finger H.

前記補強シート６を前パネル２と後パネル３の間に一体的に融着するためのシールは、直線状又は曲線状に形成された複数列のシール線８（図３）に限定されるものではなく、所定の角度で交差させた格子模様のものでも良いし、図６の米袋２１に示すように第一の手提げ孔２４，２５の外側と補強シート２６の外形線との間を全面的にシールしてベタシール２８としたものでも良い。第二の手提げ孔２７は、第一の手提げ孔２４，２５よりも小さく形成されることは実施例１と同様である。   The seal for fusing the reinforcing sheet 6 integrally between the front panel 2 and the rear panel 3 is limited to a plurality of rows of seal lines 8 (FIG. 3) formed linearly or curvedly. Instead, a lattice pattern intersecting at a predetermined angle may be used, and as shown in the rice bag 21 in FIG. 6, the entire area between the outside of the first hand holes 24 and 25 and the outline of the reinforcing sheet 26 may be used. Alternatively, a solid seal 28 may be used. The second hand hole 27 is formed to be smaller than the first hand holes 24 and 25 as in the first embodiment.

補強シート６に不織布を採用した場合、不織布には小さな空隙が内在しているので、袋内の空間の米収容部１２（図５）と手提げ孔７との間に下口元シール９を行っても空気は流通可能であり、空気抜きの通路として利用することができる。米袋を平らに積み重ねるとき、袋内に空気が充満していると積み重ねたときに不安定となるが、手提げ孔４、５を通して空気抜きができれば安定した状態で積み重ねることが出来る。   When a nonwoven fabric is used for the reinforcing sheet 6, since a small gap is inherent in the nonwoven fabric, a lower mouth seal 9 is provided between the rice container 12 (FIG. 5) and the handbag hole 7 in the space in the bag. Also, air can be circulated and used as an air vent passage. When the rice bags are stacked flatly, if the bags are filled with air, the bags become unstable when stacked, but if the air can be vented through the hand holes 4 and 5, they can be stacked in a stable state.
