Description

本発明は、米袋に関する。   The present invention relates to a rice bag.

従来、米袋を開封するには、鋏を用いていた(例えば、特許文献1参照)。
しかし、別途鋏を用意しておく必要があり、手間がかかり、また、所望の形状に正確に米袋を裂くのは難しいという欠点があった。
そこで、本出願人は鋏を用いずに開封しやすく、他にも、多くの利点を有する米袋として、既に実用新案登録出願にて提案した(特許文献2参照)。
特開2003−221044号公報 実用新案登録第3120596号公報
Conventionally, a bag has been used to open a rice bag (see, for example, Patent Document 1).
However, it is necessary to prepare a separate paddy, which is troublesome, and it is difficult to accurately tear the rice bag into a desired shape.
Accordingly, the present applicant has already proposed a utility model registration application as a rice bag having many advantages in addition to easy opening without using a bag (see Patent Document 2).
JP 2003-221044 A Utility Model Registration No. 3120596

しかしながら、(重量の)重い米袋を手で持ち運びするには、従来の米袋では、丸抱えするか、上記特許文献2のものでは、指が痛くなるという問題があった。また、プラスチック製の米袋が指を掛けた箇所から引き裂ける虞もあった。
そこで、本発明は、重い米袋を容易に手にて持ち上げることが可能であり、不意に落下させずに、指も痛くなることなく、運ぶことができる米袋を提供することを目的とし、また、米袋の各部が引き裂けることもなく、丈夫なものを提供することを他の目的とする。
However, in order to carry a heavy (heavy) rice bag by hand, there is a problem that the conventional rice bag is rounded or the finger of the above-mentioned Patent Document 2 becomes painful. In addition, the plastic rice bag may be torn from the place where the finger is hung.
Therefore, the present invention aims to provide a rice bag that can easily lift a heavy rice bag by hand, can be carried without accidentally dropping, and without causing finger pain, Another object is to provide a durable one without tearing each part of the rice bag.

そこで、本発明は、プラスチック製の表てシート体・裏シート体の4辺を融着して米粒を封入する米袋に於て、1辺にはプラスチック製不織帯布が上記表てシート体と裏シート体にサンドイッチ状に配設され、しかも、該不織帯布はその中間部位を除いて、上記表てシート体・裏シート体に融着一体化し、かつ、上記不織帯布の上記中間部位は上記表てシート体・裏シート体の間に取っ手として、引出可能に介設されている。
また、上記不織帯布が上記中間部位を除いて上記表てシート体・裏シート体に融着一体化される融着部が上記中間部位の近傍域で、左右方向中央に向って上方傾斜状に所定傾斜角をもって配設されている。
Accordingly, the present invention provides a rice bag in which four sides of a plastic display sheet body / back sheet body are fused to enclose rice grains, and a plastic non-woven band cloth is displayed on one side of the sheet body. And the non-woven band cloth is fused and integrated with the above-mentioned sheet body / back sheet body except for the intermediate portion thereof, and the non-woven band cloth The intermediate portion is interposed as a handle between the above-described sheet body and back sheet body so that it can be pulled out.
In addition, the non-woven band fabric is fused and integrated with the sheet body and the back sheet body excluding the intermediate part, and the fusion part is inclined upward toward the center in the left-right direction in the vicinity of the intermediate part. Are arranged with a predetermined inclination angle.

本発明に係る米袋によれば、米粒がこぼれることを防ぎつつ、エアー抜きをすることができる。さらに、取っ手は、販売前の流通過程では邪魔とならず、お客が買った後に、取っ手を容易に引き出して、持ち運びが容易である。しかも、取っ手が外れてしまうこともなく、強度も十分に高く保つことができる。   According to the rice bag concerning the present invention, air can be vented while preventing rice grains from spilling. Furthermore, the handle does not get in the way in the distribution process before sale, and after the customer has bought it, the handle can be easily pulled out and carried easily. In addition, the strength can be kept sufficiently high without removing the handle.

以下、図示の実施の形態に基づき本発明を詳説する。
図1に於て、米袋20には米粒Kが封入(収納)された状態を例示する。図2は米袋20の上辺部1とその近傍域を示す拡大図であり、図5は米粒Kを吐出させるために上辺部1の一部を切り取った(取り去った)開封使用状態を示す要部拡大図である。
Hereinafter, the present invention will be described in detail based on the illustrated embodiment.
In FIG. 1, an example is shown in which rice grains K are enclosed (stored) in the rice bag 20. FIG. 2 is an enlarged view showing the upper side 1 of the rice bag 20 and the vicinity thereof, and FIG. 5 is a main part showing an unsealed use state in which a part of the upper side 1 is cut out (removed) in order to discharge the rice grains K. It is an enlarged view.

図1,図2,図5、及び、図3と図4に於て、この米袋20は、プラスチック製の矩形状の表てシート体5と裏シート体6を有し、その上辺部1・下辺部2・左辺部3・右辺部4を、高周波加熱やニクロム線加熱等のヒーティングにて融着して、図1のように、米粒Kを封入するのに用いられる。
(図示省略したが、)下辺部2は米粒Kを投入する前の状態───即ち米未投入状態───では、未融着開口状であり、(後述の)図14に於て矢印C−C間を切断して分離した状態(但し、上下は逆に描かれている)である。
そして、上辺部1には、幅寸法Wが13mm〜25mmのプラスチック製不織帯布7が、表てシート体5と裏シート体6にサンドイッチ状に配設され(図4参照)、しかも、この不織帯布7は長手方向(左右方向)の中間部位Aを除いた残部───即ち、左右両側8,8が、散点状に小融着部9を多数配設して、表てシート体5と裏シート体6に融着一体化した構造である。
この多数の小融着部9の相互間は、米粒排出(こぼれ)阻止のための小寸法の間隔Mの(小寸法)通気路10を多数形成する。
1, 2, 5, 3, and 4, the rice bag 20 has a rectangular sheet-like sheet body 5 and a back sheet body 6 made of plastic. The lower side 2, the left side 3, and the right side 4 are fused by heating such as high frequency heating or nichrome wire heating, and used to enclose rice grains K as shown in FIG.
In the state before the rice grain K is introduced (that is, the rice is not yet introduced), the lower side 2 has an unfused opening shape (not shown), and an arrow in FIG. It is the state which cut | disconnected CC and isolate | separated (however, the upper and lower sides are drawn reversely).
A plastic non-woven band cloth 7 having a width W of 13 mm to 25 mm is disposed on the upper side portion 1 in a sandwich form between the sheet body 5 and the back sheet body 6 (see FIG. 4). This non-woven fabric 7 has a remaining portion excluding the intermediate portion A in the longitudinal direction (left and right direction), that is, the left and right sides 8 and 8 are provided with a number of small fused portions 9 arranged in the form of dots. The sheet body 5 and the back sheet body 6 are fused and integrated.
A large number of (small dimension) air passages 10 having a small distance M for preventing rice grain discharge (spilling) are formed between the large number of small fused portions 9.

図6には、図2の要部拡大図を示すが、この図6中の矢印Eの如く、隣り合った小融着部9,9の間に形成される小寸法通気路10を、米袋20内の空気が排出可能である。このように、脱気口としての上記小寸法通気路10が形成されていることによって、米を封入した米袋20を積上げた際に、内部の空気がスムーズに吐出(排出)して、崩れることなく複数段に積上げ可能である。このように、不織帯布7をサンドイッチ状に挟んだ構造として、小寸法の間隔Mでは、未融着状態の不織帯布7の繊維間を通過して、空気が図6の矢印Eのように排出(吐出)する。なお、小寸法の上記間隔Mは1mm〜6mmに設定し、好ましくは、2mm〜5mmとする。上限値を越すと内部の米粒Kが外部へ出てくる(排出する)虞があり、逆に、下限値未満であると、(後述の)融着が不十分となり易く、又は、治具として余りに小さな加熱用突出子を多数形成する必要があり、製作が面倒で、また、使用時期が短いのに摩耗するような問題が生ずる。   FIG. 6 shows an enlarged view of the main part of FIG. 2. As shown by an arrow E in FIG. 6, a small-sized air passage 10 formed between the adjacent small fused parts 9, 9 is replaced with a rice bag. The air in 20 can be discharged. Thus, by forming the small-sized air passage 10 as a degassing port, when the rice bag 20 enclosing the rice is stacked, the air inside is smoothly discharged (discharged) and collapses. Can be stacked in multiple stages. As described above, the nonwoven fabric cloth 7 is sandwiched between the fibers of the non-fused nonwoven fabric cloth 7 at a small interval M, and the air passes through the arrow E in FIG. It discharges (discharges) like this. The small distance M is set to 1 mm to 6 mm, preferably 2 mm to 5 mm. If the upper limit is exceeded, internal rice grains K may come out (discharge), and conversely, if it is less than the lower limit, fusion (described later) tends to be insufficient, or as a jig It is necessary to form a large number of heating protrusions that are too small, which is troublesome to manufacture and wears even though the period of use is short.

また、不織帯布7の上記中間部位Aは、図3のように、Z字状に折畳み状態で、表てシート体5・裏シート体6の間に、引出可能に介設されている。このように、Z字状に折畳まれた中間部位Aは、図2中の矢印Fのように、引出して、取っ手11を、図2の仮想線、及び図1と図5のように、(倒立U字型に)形成できる。
なお、折畳み状態の不織帯布7に掛からないように、その中間部位Aの下縁に沿って、(不織帯布7を外して)表てシート体5と裏シート体6とを円形散点状に融着した散点融着列12を有している。図例では、多数個の円形のスポット部13を一列に並べて、散点融着列12が形成されている。なお、スポット部13としては、丸味のある形状であれば、楕円型や長円型とするも好ましく、また、散点融着列12としては、2列や3列とすることも可能である。
Moreover, the said intermediate part A of the nonwoven fabric cloth 7 is inserted in the Z-shaped folded state as shown in FIG. 3 so that it can be pulled out between the sheet body 5 and the back sheet body 6. . Thus, the intermediate portion A folded in a Z-shape is pulled out as indicated by an arrow F in FIG. 2, and the handle 11 is drawn as shown by the phantom line in FIG. 2 and FIGS. (Inverted U-shaped) can be formed.
The sheet body 5 and the back sheet body 6 are circularly formed along the lower edge of the intermediate portion A so as not to hang on the folded nonwoven fabric cloth 7 (with the nonwoven fabric cloth 7 removed). It has a dotted fusion line 12 fused in a dotted manner. In the illustrated example, a large number of circular spot portions 13 are arranged in a line to form a scattered dot fusion line 12. In addition, as long as the spot part 13 is a round shape, it is preferable that it is an elliptical shape or an oval shape, and the scattered point fusion row 12 may be 2 rows or 3 rows. .

追加説明すると、図1と図2と図5に示すように、上辺部1に於て、表てシート5と裏シート6は、散点融着列12よりも上方位置に、上方向(矢印F参照)に開口する収納袋部14を形成し、この収納袋部14の内部に、折畳状の不織帯布7の中間部位Aが、上方引出自在として収納されている。
なお、不意に折畳状の不織帯布7が矢印F方向に飛び出さないように、表てシート体5と裏シート体6を僅かに最上端縁にて融着するも好ましい。
In additional explanation, as shown in FIGS. 1, 2, and 5, the upper sheet 1 has the upper sheet 1 and the rear sheet 6 at an upper position (arrow) A storage bag portion 14 that opens to the center of the folding bag 7 is housed in the storage bag portion 14 so that it can be pulled out upward.
In addition, it is also preferable that the sheet body 5 and the back sheet body 6 are slightly fused at the uppermost end edge so that the unfolded nonwoven band fabric 7 does not jump out in the direction of the arrow F.

なお、前記収納袋部14は、左右両側8,8の小融着部9の各最内端列のものと、散点融着列12によって、左辺・右辺・下辺(底辺)を包囲した、上方開口状袋状であるといえる。
また、不織帯布7の中間部位Aは、図3(A)のようにZ字状に折畳まれる場合に限らず、Z字状とS字状とを組み合わせたり、長手方向にZ字状を複数形成する等の他の折畳み形状とするも自由である(図示省略)。
The storage bag portion 14 encloses the left side, the right side, and the lower side (bottom side) with the innermost end row of each of the small fused portions 9 on both the left and right sides 8 and 8 and the scattered point fused row 12. It can be said that it is an upper opening bag shape.
Further, the intermediate portion A of the nonwoven fabric cloth 7 is not limited to the case where it is folded in a Z shape as shown in FIG. Other folding shapes such as forming a plurality of character shapes are also free (not shown).

次に、図1〜図7に示すように、散点状の上記小融着部9は、楕円状乃至長円形状である。しかも、左右方向中央に向かって上方傾斜状に所定傾斜角θをもって、全ての楕円状乃至長円形状の小融着部9は配設されている。
なお、多数の小融着部9の内で、少なくとも中間部位Aの近傍域───つまり、収納袋部14の左辺・右辺を形成する小融着部9───では、左右中央に向かって上方傾斜状に傾斜角θをもって配設する。上記傾斜角θとしては、30°〜60°とするのが好ましく、特に、40°〜50°が、望ましい。その理由は、図1と図5のように、取っ手11として、引き出した不織帯布7を上方へ引き上げる力が作用した際に、取っ手11の左右の下端部に作用する上方向の外力に沿った方向に、小融着部9が傾斜していて、強度上有利となるからである。
Next, as shown in FIGS. 1 to 7, the dotted small fused part 9 has an elliptical shape or an oval shape. In addition, all the elliptical or oval small fused portions 9 are disposed with a predetermined inclination angle θ in an upward inclination toward the center in the left-right direction.
Of the large number of small fused portions 9, at least in the vicinity of the intermediate portion A--that is, in the small fused portions 9 forming the left and right sides of the storage bag portion 14--toward the left and right center. Are arranged in an upwardly inclined shape with an inclination angle θ. The inclination angle θ is preferably 30 ° to 60 °, and particularly preferably 40 ° to 50 °. The reason for this is that, as shown in FIGS. 1 and 5, when a pulling force is applied to the pulled-out nonwoven fabric 7 as the handle 11, the upward external force acting on the left and right lower ends of the handle 11 is applied. This is because the small fused portion 9 is inclined in the direction along which it is advantageous in strength.

図2と図7と図8に於て、不織帯布7の左右両側8,8の内の一方───図例では左側───と、中間部位Aとの境界域Zにおいて、切り取り線部15が形成されている。つまり、この切り取り線部15は、不織帯布7を上下方向(幅方向)に、横切るように、表てシート体5と不織帯布7と裏シート体6とを、上下帯状(上下線状)に融着して形成されている。
即ち、図7及び(そのD−D断面を示す)図8に示す如く、手でもって破断が難しいプラスチック不織布から成る不織帯布7を、上下方向の帯状(線状)に一旦融かすことで、裂け易くしており、切り取り線部15に沿って手で容易に引き裂くことが可能となる。そして、この切り取り線部15の下端から、左方向に水平状に切り取り線部16を連結形成する。これによって、図1と図2から、図5のような、切り取りが可能となる。即ち、不織帯布7の左側8の部位は、切り取られて、そこが、米吐出口17を形成する。
なお、図7のように、小さなV型ノッチ18や引裂き開始短線切り目を、切り取り線部15の最上端に形成するのが好ましい。また、図7のように、ミシン目19を付加形成しても好ましい。
2, 7, and 8, cut out at one of the left and right sides 8, 8 of the nonwoven fabric cloth 7, the left side in the example, and the boundary zone Z between the intermediate portion A. A line portion 15 is formed. That is, the cut line portion 15 represents the sheet body 5, the nonwoven band cloth 7, and the back sheet body 6 so as to cross the nonwoven fabric cloth 7 in the vertical direction (width direction). Linearly).
That is, as shown in FIG. 7 and FIG. 8 (showing its DD cross section), the non-woven belt fabric 7 made of a plastic nonwoven fabric that is difficult to break by hand is once melted into a belt shape (linear shape) in the vertical direction. Therefore, it can be easily torn and can be easily torn along the cut line portion 15 by hand. Then, from the lower end of the cut line portion 15, the cut line portion 16 is connected and formed horizontally in the left direction. Thereby, from FIG. 1 and FIG. 2, it becomes possible to cut out as shown in FIG. That is, the left side 8 portion of the nonwoven fabric 7 is cut out to form a rice discharge port 17.
As shown in FIG. 7, it is preferable to form a small V-shaped notch 18 and a tear start short cut at the uppermost end of the cut line portion 15. Further, as shown in FIG. 7, a perforation 19 may be additionally formed.

次に、図1と図15(A)に示すように、表てシート体5と裏シート体6の左辺部3・右辺部4を、相互に融着する融着帯部23, 24は、上下中間位置が幅広として、米収納部21の上下中間位置に絞り部(くびれ部)25が形成される。このように構成すれば、内部の米粒Kが下へ移動するのを防ぎ、安定した美しい外観・姿勢に、立てることができる。つまり、図15(B)は従来の米袋40であり、米粒が下方へ移動して、美しい外観とは言えない。これに対して、本発明のものは、図15(A)に示す如く、腰がくびれて米がいっぱい収納されているように美しく見え、かつ、美しい姿勢で立てることができる。   Next, as shown in FIG. 1 and FIG. 15 (A), the fusion band portions 23 and 24 for fusing the left side portion 3 and the right side portion 4 of the sheet body 5 and the back sheet body 6 to each other, A narrowed portion (constricted portion) 25 is formed at the upper and lower intermediate positions of the rice storage portion 21 with the upper and lower intermediate positions being wide. If comprised in this way, it can prevent that the internal rice grain K moves below, and can stand in the stable beautiful external appearance and attitude | position. That is, FIG. 15 (B) is a conventional rice bag 40, and the rice grains move downward, and it cannot be said that the appearance is beautiful. On the other hand, as shown in FIG. 15 (A), the present invention can be stood in a beautiful posture and looks beautiful as if the waist is constricted and a lot of rice is stored.

次に、図9〜図14は、上述の米袋20を製作するための連続シート26の製造方法を示す。即ち、図9に示すように、帯状(長尺)の第1プラスチックシート31と、帯状(長尺)の第2プラスチックシート32を、相互間隔Hがしだいに接近するように間欠的に送りGを与える。このとき、巻設ロール33, 34から、第1・第2プラスチックシート31, 32が間欠的に送り出される(繰出される)。
他方、別のロール35には、帯状(長尺)のプラスチック不織布36が予め巻設されており、しかも、図10に示す如く、このプラスチック不織布36は、横断面Z字状等に予め(幅方向に)折畳まれて、不織布ロール35に(ロール状に)巻設されている。折畳みの横断面形状は、Z字状以外に、Z字状とS字状を組み合わせた形状、あるいは、2つ以上のZ字状又はS字状としたもの等、最終の図3等に示した折畳形状に対応して、予め折畳まれて不織布ロール35に巻設されている。この不織布ロール35から、長尺の不織布36を繰出しつつ、送りJを与える。この長尺帯状の不織布36の送りJは間欠的であり、かつ、第1・第2プラスチックシート31, 32の送りGと同一方向である。
Next, FIGS. 9 to 14 show a manufacturing method of the continuous sheet 26 for manufacturing the rice bag 20 described above. That is, as shown in FIG. 9, the belt-like (long) first plastic sheet 31 and the belt-like (long) second plastic sheet 32 are intermittently fed so that the mutual distance H gradually approaches G. give. At this time, the first and second plastic sheets 31 and 32 are intermittently fed out (wound out) from the winding rolls 33 and 34.
On the other hand, a belt-like (long) plastic nonwoven fabric 36 is wound around another roll 35 in advance, and as shown in FIG. It is folded (in the direction) and wound around the non-woven roll 35 (in a roll). The cross-sectional shape of the folding is shown in the final FIG. 3, etc., such as a Z-shaped and S-shaped combination, or two or more Z-shaped or S-shaped, in addition to the Z-shaped Corresponding to the folded shape, it is folded in advance and wound around the nonwoven fabric roll 35. Feed J is given from the nonwoven fabric roll 35 while feeding the long nonwoven fabric 36. The feed J of the long belt-like nonwoven fabric 36 is intermittent and is in the same direction as the feed G of the first and second plastic sheets 31 and 32.

図9と図11, 図12に示すように、第1・第2プラスチックシート31, 32の間に、その幅方向に多角筒型の受けローラ37が設置されており、例えば、六角形や八角形の筒型であり、その内部37Aは、バキューム手段に連通連結されて、真空に保持され、かつ、この受けローラ37の外壁には、多数の吸込孔が開設されていて、矢印J方向に間欠的に送られてくる不織布36は、吸込孔からの空気の吸込みにて、吸着されて、図9と図11のように、多角形の一辺に吸い着く。しかも、この多角筒型の受けローラ37は第1プラスチックシート31にも接近するように、配置されており、この図9と図11の状態でヒーティングされた仮付け用加熱押し具38を矢印N方向に押圧して、スポット状に第1プラスチックシート31に不織布36の先端を、仮付け41する。つまり、まな板の如き作用を、受けローラ37が果たす。   As shown in FIGS. 9, 11, and 12, a polygonal cylindrical receiving roller 37 is installed in the width direction between the first and second plastic sheets 31, 32. The inner cylinder 37A is connected to the vacuum means and is held in a vacuum, and a number of suction holes are formed in the outer wall of the receiving roller 37 in the direction of arrow J. The nonwoven fabric 36 sent intermittently is adsorbed by the suction of air from the suction holes, and is attracted to one side of the polygon as shown in FIGS. In addition, the polygonal cylindrical receiving roller 37 is arranged so as to be close to the first plastic sheet 31, and the heating pressing tool 38 for temporary attachment heated in the state of FIGS. The tip of the nonwoven fabric 36 is temporarily attached 41 to the first plastic sheet 31 by pressing in the N direction. That is, the receiving roller 37 performs an action like a cutting board.

さらに、六角筒型の受けローラ37の角部(稜線部)39には、溶断刃(又は機械的切断刃)42が付設されており、従って、図11の状態で、不織布36は、この溶断刃(又は切断刃)42にて、幅方向の切断も同時に行われて、不織帯布7を形成する。即ち、切断にて不織帯布7を形成すると共に、第1プラスチックシート31に仮付けする。
ところで、図11における溶断刃42を用いた場合、溶断の熱によって、図3に示した中間部位(折畳み部)Aの幅方向両端縁(同図の上辺と下辺)が相互に融着して、折畳み部に外力を与えなければ、展開せず、従って、図2の矢印F方向に、不意に折畳み部が飛び出すことを防止できる。
第1プラスチックシート31の前記送りGに伴って、仮付けされた不織帯布7は下流へ送られ、図9に示す融着装置43によって、第1・第2プラスチックシート31, 32の間にサンドイッチ状として、不織帯布7を融着一体化する。このとき、同時に、左右辺部3,4も融着する。
Further, a fusing blade (or mechanical cutting blade) 42 is attached to the corner (ridge line portion) 39 of the hexagonal cylindrical receiving roller 37. Therefore, in the state of FIG. The blade (or cutting blade) 42 is also cut in the width direction at the same time to form the nonwoven fabric cloth 7. That is, the non-woven fabric 7 is formed by cutting and temporarily attached to the first plastic sheet 31.
When the fusing blade 42 in FIG. 11 is used, both ends in the width direction (upper side and lower side) of the intermediate portion (folded portion) A shown in FIG. If an external force is not applied to the folding part, the folding part is not unfolded. Therefore, it is possible to prevent the folding part from unexpectedly popping out in the direction of arrow F in FIG.
Along with the feeding G of the first plastic sheet 31, the temporarily attached nonwoven fabric 7 is fed downstream, and is fused between the first and second plastic sheets 31 and 32 by a fusing device 43 shown in FIG. The nonwoven fabric cloth 7 is fused and integrated as a sandwich. At the same time, the left and right side portions 3 and 4 are also fused.

図12と前述の図1とを比較すれば、分かるように、下辺部2の融着は未だ行われておらず、上辺部1の融着、及び、左辺部3・右辺部4の融着は、この時に、既に行われていることとなる。そして、図9と図12に符号Pにて示した1ピッチ分が、その後の図14と図13で示した切断工程にて切断されて、1個の米袋20を構成する。   As can be seen from a comparison between FIG. 12 and FIG. 1 described above, the lower side portion 2 has not been fused yet, the upper side portion 1 is fused, and the left side portion 3 and the right side portion 4 are fused. This is already done at this time. 9 and FIG. 12 is cut by one pitch indicated by the reference symbol P in the subsequent cutting step shown in FIGS. 14 and 13 to form one rice bag 20.

図9と図12のように、未切断(非分離の連続帯状)の米袋用連続シート26は、通常は、一旦、ロール状に巻設して、保管される。
その後、米投入機45にて米粒Kを投入するには、図13及び図14に示すように、図1とは上下逆として、送りQを与え、上端としての下辺部2を、吸盤46, 46にて吸引47, 47して開口状として、ホッパー48から米粒Kの投入を行うと共に、直後に、上端としての下辺部2を、図外の融着機(超音波又は熱融着)にて融着して、米粒Kを封入し、さらに、矢印C,Cのように、切断する。
この切断によって、図1に於て、取っ手11が、引き出される前の状態───収納袋部14に収納された状態───のものが、得られる。
本発明に於て、表てシート体5・裏シート体6は、例えば、ナイロン製の外層と、ポリエチレン又はポリプロピレン製の内層を装着一体化したものから成る。また、不織帯布7は、ナイロン、ポリエチレン、又は、ポロプロピレン等のプラスチックとする。
As shown in FIG. 9 and FIG. 12, the uncut (non-separated continuous belt-shaped) rice bag continuous sheet 26 is usually wound once in a roll and stored.
Thereafter, in order to put rice grains K in the rice thrower 45, as shown in FIG. 13 and FIG. 14, the feed Q is given upside down from FIG. At 46, suction 47, 47 is made into an opening, and rice grains K are introduced from the hopper 48. Immediately after that, the lower side 2 as the upper end is attached to a fusion machine (ultrasonic or heat fusion) not shown. Then, the rice grains K are sealed and further cut as indicated by arrows C and C.
By this cutting, a state in which the handle 11 is in a state before being pulled out--a state in which the handle 11 is stored in the storage bag portion 14--is obtained in FIG.
In the present invention, the sheet body 5 and the back sheet body 6 are composed of, for example, a nylon outer layer and a polyethylene or polypropylene inner layer mounted and integrated. Moreover, the nonwoven fabric cloth 7 is made of plastics such as nylon, polyethylene, or polypropylene.

本発明は、上述のように、プラスチック製の表てシート体5と裏シート体6の上辺部1・下辺部2・左辺部3・右辺部4を融着して米粒Kを封入する米袋に於て、上記下辺部2は米未投入状態では未融着開口状であると共に、上記上辺部1はプラスチック製不織帯布7が上記表てシート体5と裏シート体6にサンドイッチ状に配設され、しかも、該不織帯布7はその中間部位Aを除いて、左右両側8,8が米粒排出阻止のための小寸法通気路10を多数形成するように散点状に小融着部9を多数配設して上記表てシート体5・裏シート体6に融着一体化し、かつ、上記不織帯布7の上記中間部位Aは折畳み状態で上記表てシート体5・裏シート体6の間に取っ手11として、引出可能に介設されているので、不織帯布7は、流通過程では収納状態で邪魔とならず、しかも、消費者に於ては、簡単に引き出して、取っ手11として、重い米を持ち運びが容易であって、至便である。また、取っ手11の付け根に相当する部分───散点状の小融着部9が多数配設した部分───は、応力が分散して、応力集中を生じないので、引き裂き等の強度上の問題が生じない利点もある。 さらに、米袋を積上げたときに、内部の空気がスムーズに排出されて、コンパクトに積上げ得る。   As described above, the present invention provides a rice bag that encloses rice grains K by fusing the upper side 1, the lower side 2, the left side 3, and the right side 4 of the plastic front sheet body 5 and back sheet body 6. In this case, the lower side portion 2 has an unfused opening shape when no rice is introduced, and the upper side portion 1 is sandwiched between the sheet body 5 and the back sheet body 6 by the plastic non-woven fabric cloth 7 appearing above. Furthermore, the nonwoven fabric cloth 7 is small in the form of dots so that the left and right sides 8 and 8 form a large number of small-sized air passages 10 for preventing rice grain discharge except for the intermediate portion A. A large number of attachment portions 9 are arranged and fused and integrated with the above-described sheet body 5 and the back sheet body 6, and the intermediate portion A of the nonwoven fabric cloth 7 is folded and the above-described sheet body 5. As the handle 11 is interposed between the back sheet body 6 so as to be able to be pulled out, the nonwoven fabric cloth 7 is stored in the distribution process. It is not in the way, and it is convenient for the consumer to easily pull out and carry heavy rice as the handle 11. In addition, the portion corresponding to the base of the handle 11--the portion where a large number of scattered small fused portions 9 are arranged--is dispersed in the stress and does not cause stress concentration. There is also an advantage that the above problems do not occur. Further, when the rice bags are stacked, the air inside is smoothly discharged, and the rice bags can be stacked compactly.

また、折畳み状態の上記不織帯布7の中間部位Aの下縁に沿って、上記表てシート体5と上記裏シート体6とを円形散点状に融着した散点融着列12を有しているので、内部の空気を一層スムーズに排出でき、かつ、円形散点状の融着であるので、(四角形散点状に比して)亀裂を生じず、強度的に有利である。   Further, a scattered dot fusion line 12 in which the above-mentioned sheet body 5 and the back sheet body 6 are fused in a circular dotted shape along the lower edge of the intermediate portion A of the nonwoven fabric cloth 7 in the folded state. Therefore, the inner air can be discharged more smoothly and fused in the form of circular scattered dots. is there.

また、散点状の上記小融着部9が楕円状乃至長円形状であって、少なくとも上記中間部位Aの近傍域では、左右方向中央に向かって上方傾斜状に所定傾斜角θをもって配設されているので、取っ手11を手で持った状態で、取っ手11の付け根部を介して作用する上方向の外力に沿って、楕円状乃至長円形状の小融着部9が配置されていることとなり、無理なく、表てシート体5・裏シート体6から取っ手11へ力が伝達され、引き裂かれるような問題を防止できる。   In addition, the scattered small fusing portions 9 are elliptical or oval in shape, and at least in the vicinity of the intermediate portion A, are arranged with a predetermined inclination angle θ in an upward inclination toward the center in the left-right direction. Since the handle 11 is held by hand, an elliptical or oval small fused portion 9 is arranged along the upward external force acting via the base portion of the handle 11. Thus, it is possible to prevent a problem that the force is transmitted from the sheet body 5 and the back sheet body 6 to the handle 11 and is torn.

また、上記不織帯布7の上記左右両側8,8の内の一方と、上記中間部位Aとの境界域Zにおいて、該不織帯布7と上記表てシート体5と上記裏シート体6とを、該不織帯布7を上下方向に横切るように融着した切り取り線部15を形成したので、切り取り線部15に沿って、(引き裂き難い不織帯布7を横切って)容易に引き裂いて、(切り取って、)米の吐出口を形成できる。   Further, in the boundary zone Z between one of the left and right sides 8 and 8 of the nonwoven fabric cloth 7 and the intermediate portion A, the nonwoven fabric cloth 7, the display sheet body 5 and the back sheet body. 6 is formed so that the non-woven band cloth 7 is welded so as to cross the non-woven band cloth 7 in the vertical direction. Torn (cut out) to form a rice outlet.

また、上記表シート体5と裏シート体6の上記左辺部3・右辺部4を、相互に融着する融着帯部23,24は、上下中間位置が幅広として、米収納部21の上下中間位置に絞り部25を形成したので、図15(B)に示した従来の米袋40のように、米粒が過分に下へ集まって、米粒が十分に充満していないような感じを与えることを防止し、図15(A)に示すように、美しい姿勢で、立てることができ、かつ、米粒も下へ移動し過ぎないようにできる。   Further, the fusion band portions 23 and 24 for fusing the left side portion 3 and the right side portion 4 of the front sheet body 5 and the back sheet body 6 to each other are wide at the upper and lower intermediate positions, so Because the squeezed portion 25 is formed in the middle position, the rice grains are excessively gathered down like the conventional rice bag 40 shown in FIG. 15 (B), giving the feeling that the rice grains are not fully filled As shown in FIG. 15A, it is possible to stand in a beautiful posture and prevent the rice grains from moving too much downward.

次に、本発明の米袋用連続シートの製造方法によれば、帯状の第1プラスチックシート31と帯状の第2プラスチックシート32を、相互間隔Hがしだいに接近するように送りGを与えつつ、帯状のプラスチック不織布36を該送りGと同一の方向に送りJを与えつつ、該プラスチック不織布36を幅方向に切断して、不織帯布7を形成すると共に、該不織帯布7を上記第1・第2プラスチックシート31,32のいずれか一方に仮付け41して、前記送りGにて下流へ送り、上記第1・第2プラスチックシート31,32の間にサンドイッチ状として上記不織帯布7を融着一体化すると同時に、左右辺部3,4を融着する幅寸法Wの小さい不織帯布7を、巧妙にシート幅方向に設けることができる。しかも、一般の米投入機45を、図13のように、そのまま、使用できる。   Next, according to the method for producing a continuous sheet for rice bags of the present invention, while feeding the belt-shaped first plastic sheet 31 and the belt-shaped second plastic sheet 32 so that the mutual distance H gradually approaches, While the belt-shaped plastic nonwoven fabric 36 is fed in the same direction as the feed G, the plastic nonwoven fabric 36 is cut in the width direction to form the nonwoven fabric cloth 7, and the nonwoven fabric cloth 7 is Temporarily attach 41 to one of the first and second plastic sheets 31 and 32, and feed downstream with the feed G. The nonwoven fabric is sandwiched between the first and second plastic sheets 31 and 32. At the same time as the band cloth 7 is fused and integrated, the non-woven band cloth 7 having a small width W for fusing the left and right side portions 3 and 4 can be skillfully provided in the sheet width direction. Moreover, a general rice feeder 45 can be used as it is as shown in FIG.

さらに、上記プラスチック不織布36は、横断面Z字状となるように、予め折畳まれてロール状に巻設され、このロール状に巻設された不織布ロール35から繰出しつつ送りJを与えることによって、幅寸法Wの小さい不織帯布7を巧妙に折畳み状に、第1・第2プラスチックシート31, 32間に介設できる。   Further, the plastic nonwoven fabric 36 is folded in advance so as to have a Z-shaped cross section and wound in a roll shape, and by feeding out the nonwoven fabric roll 35 wound in this roll shape, the feed J is given. The nonwoven fabric cloth 7 having a small width dimension W can be cleverly folded between the first and second plastic sheets 31 and 32.
