Description

この発明は、ロールペーパー用包装袋に関する。   The present invention relates to a packaging bag for roll paper.

従来、キッチンペーパーやトイレットロールなどのロールペーパーを複数段積み重ねた状態で包装する包装袋として、樹脂ビニール等のフィルムで形成したロールペーパー用包装袋(以下、単に包装袋とも言う。)が広く普及している。   2. Description of the Related Art Conventionally, roll paper packaging bags (hereinafter simply referred to as packaging bags) formed of a film such as resin vinyl have been widely used as packaging bags for packaging roll paper such as kitchen paper and toilet rolls in a plurality of stacked layers. are doing.

このような包装袋の中には、包装袋の上端面中央に形成した開口線部から、その左右の包装袋上端面に沿って二又分岐の破断線を入れて、開口線部を最初に破断した後に、包装袋上端面の二又分岐破断線に沿って続いて破断していくことにより、容易に包装袋の上面を開口して内収容のロールペーパーを取出し可能にしたものがある(例えば、特許文献1及び特許文献2参照。)。   In such a packaging bag, from the opening line formed in the center of the upper end surface of the packaging bag, make a bifurcated branch line along the upper end surfaces of the left and right packaging bags, and place the opening line first. After the rupture, the wrapping bag is successively ruptured along a bifurcated break line on the upper end surface, so that the upper surface of the wrapping bag can be easily opened to take out the roll paper contained therein ( For example, see Patent Literature 1 and Patent Literature 2.)

実開昭60−8260号公報Japanese Utility Model Publication No. 60-8260 特許3153528号公報Japanese Patent No. 3153528

しかし、これらの包装袋上面の二又分岐の破断線では、破断線に沿って包装袋を正確に破れず破断線からはずれて多方向に破れ、結局はロールペーパーの取出しに適合した正確な開口部の形成ができない。   However, at the bifurcated break line on the top of these packaging bags, the packaging bag is not broken exactly along the break line, but breaks from the break line and breaks in multiple directions. No part can be formed.

その理由は次のような破断線の不連続孔の形状と、この破断線に沿ってフィルムを引きちぎっていく開口作業形態にある。包装袋上面に形成された破断線は、線状又は点状の複数の刻設溝を所定幅のつなぎ部分を間に介在させつつ同一線上に配置して貫通形成している。   The reason is the shape of the discontinuous hole of the breaking line as described below and the opening work form of tearing the film along the breaking line. The breaking line formed on the upper surface of the packaging bag is formed by penetrating a plurality of linear or dot-shaped engraving grooves by arranging them on the same line with a connecting portion having a predetermined width interposed therebetween.

すなわち破断線の破断作業は、同破断線に沿って始端部から終端部に沿って引っ張ることにより行われると共に、その破断線の引張り方向は隣接する刻設溝に沿って行われる。   That is, the breaking operation of the breaking line is performed by pulling the starting line from the starting end to the ending portion along the breaking line, and the breaking direction of the breaking line is performed along the adjacent engraved groove.

このように従来の包装袋における破断線に沿った破断作業は、包装袋上端面の二又分岐破断線に囲まれたフィルム面を破断線に沿って引っ張り上げるようにして行うため、破断線の中途部で偏奇した方向への裂け目を生じさせ、正確に破断線に沿って行われずロール取り出し用の開口部を正しく形成できない。   As described above, the breaking operation along the breaking line in the conventional packaging bag is performed by pulling up the film surface surrounded by the bifurcated breaking line on the upper end surface of the packaging bag along the breaking line. A tear in an eccentric direction occurs in the middle part, and it is not performed exactly along the break line, and the roll take-out opening cannot be formed correctly.

力学的には、開封部を袋面から引っ張りあげた際の応力は、フィルム面の面方向に直交する上側方向(袋の外側方向)の応力となる。   Mechanically, the stress when the opening portion is pulled up from the bag surface is a stress in an upper direction (outer direction of the bag) orthogonal to the surface direction of the film surface.

このような上側方向の引張り応力は隣接する刻設溝同士の間のつなぎ部分にかかり、刻設溝からつなぎ部分に該引張り応力が引張り方向の偏奇荷重によりずれてしまい、つなぎ部分から円滑にその次の刻設溝に至らずはみ出し破裂を生起して規定の破断線に沿って破れないため、所定の取出し開口部を形成できないことが多い。   Such an upward tensile stress is applied to a joint portion between adjacent engraved grooves, and the tensile stress is shifted from the engraved groove to the joint portion by an uneven load in the tensile direction, and the tensile stress is smoothly applied from the joint portion. A predetermined extraction opening cannot be formed in many cases because the protrusion does not reach the next engraved groove and does not break along a predetermined breaking line due to a protruding burst.

仮に袋面に過度な上側方向の応力を付与した場合には、該応力は袋の撓み変形やつなぎ部分の伸延変形も相俟って、破断線の刻設溝端部の伸延方向からズレた偏奇ねじれ方向で負荷されることとなる。   If an excessively upward stress is applied to the bag surface, the stress is combined with the bending deformation of the bag and the extension deformation of the joint portion, and the bias is shifted from the extension direction of the cut groove end of the breaking line. Load will be applied in the twisting direction.

その結果、偏奇ねじれ方向の応力が、つなぎ部分に破断線の伸延方向から位置ズレした「偏奇切込み」を発生させ、この「偏奇切込み」をきっかけに破断線から外れた開封部や袋本体に向かう「無用な裂け」を生じさせていた。   As a result, the stress in the eccentric torsion direction generates a “eccentric notch” that is displaced from the direction of extension of the break line at the joint portion, and the “skew notch” triggers the opening portion or the bag body deviating from the break line. Causing "useless tears".

このように従来の包装袋は、袋面に上側方向の応力を付与した場合には、袋本体上面で開封部を破断線に沿って正しく破断できず、包装袋を破損させて袋内に収納している未使用のロールペーパーの保管状態を悪化させていた。   As described above, in the conventional packaging bag, when an upward stress is applied to the bag surface, the opening portion cannot be broken correctly along the breaking line on the upper surface of the bag body, and the packaging bag is damaged and stored in the bag. The storage condition of unused roll paper was worsened.

本発明は、かかる事情に鑑みてなされたものであって、包装袋に「無用な裂け」を生起させることなく破断線の伸延方向に沿って開封部を正しく破断して袋上面にロールペーパーの取り出し用の開口部を形成することができ、包装袋の開封作業を簡単に行うことができ、開封後には収納している未使用のロールペーパーの保管状態を良好にすることができるロールペーパー用包装袋を提供する。   The present invention has been made in view of the above circumstances, and correctly breaks the opening portion along the extension direction of the break line without causing `` unnecessary tearing '' in the packaging bag, and roll paper on the bag upper surface. An opening for taking out can be formed, the opening operation of the packaging bag can be easily performed, and after opening, the stored state of the unused roll paper stored is good for roll paper. Provide packaging bags.

上記従来の課題を解決するために、本発明に係るロールペーパー用包装袋では、略方形状に保形したビニール筒体の上部開口端縁において、筒体開口端左右に略三角形折込部を形成して、この略三角形折込部上に重複する状態で先端部合せ溶着形状の前後カバー体を折曲形成し、しかも前後カバー体は、先端合せ部を引上げ緊張した際に傾斜状に緊張変態すべく構成し、また、前後カバー体の先端合せ部には、指用孔を形成し、先端合せ部から前後カバー体にかけて二又に分岐した破断線を刻設し、破断線は、各刻設溝を円弧状又は山型状の拡開溝に形成して、かつ一定間隔で連続して設け、緊張変態化した前後カバー体表面への手掌による下方押圧力により破断線に沿って破断を可能に構成したことを特徴を有する。   In order to solve the above-mentioned conventional problems, in the roll paper packaging bag according to the present invention, substantially triangular folds are formed on the left and right sides of the opening end of the cylindrical body at the upper opening edge of the vinyl cylinder maintained in a substantially square shape. Then, the front and rear cover bodies having the front end welded shape are bent and formed in an overlapping state on the substantially triangular folded portion, and the front and rear cover bodies are inclinedly transformed when the front end joint is pulled up and tightened. In addition, a finger hole is formed in the front end of the front and rear cover body, and a bifurcated break line is engraved from the front end of the front body to the front and rear cover body. Grooves are formed in arc-shaped or mountain-shaped widening grooves and are provided continuously at regular intervals, and can be broken along the breaking line by the downward pressing force of the palm on the front and rear cover bodies that have been transformed into tension. It has the feature of having comprised to it.

本発明によれば、略方形状に保形したビニール筒体の上部開口端縁において、筒体開口端左右に略三角形折込部を形成して、この略三角形折込部上に重複する状態で先端部合せ溶着形状の前後カバー体を折曲形成し、しかも前後カバー体は、先端合せ部を引上げ緊張した際に傾斜状に緊張変態すべく構成し、また、前後カバー体の先端合せ部には、指用孔を形成し、先端合せ部から前後カバー体にかけて二又に分岐した破断線を刻設し、破断線は、各刻設溝を円弧状又は山型状の拡開溝に形成して、かつ一定間隔で連続して設け、緊張変態化した前後カバー体表面への手掌による下方押圧力により破断線に沿って破断を可能に構成したため、予め先端合せ部を引上げて前後カバー体を斜めに緊張させ、緊張したフィルム面の面方向に対して下側の押圧応力をかけると、刻設溝端部に下方押圧応力を効果的に集中させることができる。   According to the present invention, substantially triangular folds are formed on the left and right sides of the open end of the cylindrical body at the upper opening edge of the substantially cylindrically shaped vinyl cylindrical body, and the front end is overlapped on the substantially triangular fold. The front and rear cover body is formed by bending the front and rear cover body, and the front and rear cover body is configured to be inclined and transformed when the front end is pulled up and tightened. , A finger hole is formed, a bifurcated break line is engraved from the front end fitting part to the front and rear cover body, and the break line is formed by forming each engraved groove into an arc-shaped or mountain-shaped expanded groove. And, it is provided continuously at a constant interval, and it is configured to be able to break along the breaking line by the downward pressing force by the palm on the front and rear cover body which has been transformed into tension, so that the front and rear cover parts are pulled up in advance and the front and rear cover bodies are pulled up. Tension obliquely, and lower the film direction When applying a pressing stress, lower pressing stress in time 設溝 end can be effectively concentrated.

その結果、つなぎ部分に刻設溝の拡開端部の伸延方向を裂け方向とした「切込線」を生起することができ、隣接する刻設溝の端部から伸延してきた切込線同士が互いに交差合流することにより刻設溝同士の間に介在するつなぎ部分を正確に裂断することができる。   As a result, it is possible to generate a “cut line” in which the extension direction of the enlarging end of the engraved groove is a tearing direction at the joint portion, and the cut lines extending from the ends of the adjacent engraved grooves can be generated. By intersecting with each other, the connecting portion interposed between the engraved grooves can be accurately torn.

すなわち、包装袋に「無用な裂け」を生起させることなく破断線の伸延方向に沿って開封部を正しく破断して袋上面にロールペーパーの取り出し用の開口部を形成することができ、包装袋の開封作業を簡単に行うことができ、開封後には収納している未使用のロールペーパーの保管状態を良好にすることができる効果がある。   That is, the opening portion for taking out the roll paper can be formed on the upper surface of the bag by properly breaking the opening portion along the extension direction of the breaking line without causing “unnecessary tearing” in the packaging bag. Can easily be opened, and after opening, there is an effect that the stored state of unused roll paper can be improved.

また、前記先端合せ部は、包装袋の幅方向に沿って溶着形成したシール部と、前記シール部上方で人手で把持するための把持部と、で構成し、前記シール部は、間欠的に溶着形成しているため、ロールペーパーの包装作業において、袋本体部の下方開口から上方に向けてロールペーパーを袋本体部内へ挿入収納する際に流入した空気がシール部同士の間にある隙間から外部へ排気されて、袋本体部上部における内圧の異常な高まりを抑制してシール部や破断線を袋本体部の内側から破損することを防止できる効果がある。   Further, the front end fitting portion is composed of a seal portion formed by welding along the width direction of the packaging bag, and a grip portion for manually gripping the seal portion, and the seal portion is intermittently formed. Due to the formation of the welding, in the roll paper packaging operation, the air that has flowed in when the roll paper is inserted upward from the lower opening of the bag body into the bag body is stored in the gap between the seal portions. When the air is exhausted to the outside, an abnormal increase in the internal pressure in the upper portion of the bag body is suppressed, and there is an effect that the seal portion and the break line can be prevented from being damaged from the inside of the bag body.

また、前記把持部には、前記把持部の上縁から上下方向に伸延し、その先端で前記破断線の拡開頂部と連結する点状又は直線状の複数の刻設溝からなる第2の破断線を形成したため、第2の破断線を中心に把持部を幅方向左右側に引っ張ることにより、把持部中央に第2の破断線に沿った切れ込みを生起して把持部を左右に分割することができるともに、第2の破断線の終端で分岐する下方拡開状の破断線に沿って切込みを延長させて開封部を中央に残しつつ袋本体部の上部を左右に分割することができ、ロールペーパーの取り出し用開口部を大きく形成することができる効果がある。   Further, the grip portion includes a plurality of point-like or linear engraving grooves extending vertically from an upper edge of the grip portion and connected to an expanded top portion of the break line at a tip thereof. Since the break line is formed, the grip portion is pulled left and right around the second break line, thereby generating a cut along the second break line at the center of the grip portion and dividing the grip portion into right and left. The upper part of the bag body can be divided into left and right parts while extending the cut along the downwardly expanding breaking line that branches off at the end of the second breaking line, leaving the opening part in the center. This has the effect that the opening for taking out the roll paper can be made large.

また、前記第2の破断線は、前記把持部の表裏面において互いに左右方向にずらして形成しているため、持ち運び時に加わる引っ張り荷重を分散させ、把持部が不用意に左右分割することを防止できる効果がある。   Further, since the second breaking line is formed so as to be shifted in the left-right direction on the front and back surfaces of the grip portion, the tensile load applied at the time of carrying is dispersed, thereby preventing the grip portion from being inadvertently split right and left. There is an effect that can be done.

The width of the pores 30b and 31b is wider than the width of the pores 30b, thereby improving the efficiency of exhausting the internal air during the work of inserting the roll paper R.

要するに、シール部は、一定方向に連続的に溶着形成した所定箇所でロールペーパーRの内挿作業時における内部空気を排気するための通気孔を形成していればよい。例えば、把持部20両端部のみに通気孔30b、31bを形成することともしてもよい。また、各シール部30を形成するシールスポット30aの形状は、方形状に限定されることはなく、例えば、線状、円状、三角状であってもよい。   In short, the seal portion only needs to form a ventilation hole for exhausting the internal air at the time of the insertion operation of the roll paper R at a predetermined location continuously formed by welding in a certain direction. For example, the ventilation holes 30b and 31b may be formed only at both ends of the grip portion 20. Further, the shape of the seal spot 30a forming each seal portion 30 is not limited to a square shape, and may be, for example, a linear shape, a circular shape, or a triangular shape.

また、前後カバー体10b、10b’の先端合せ部2には、指用孔23を形成している。具体的には、把持部20の中央部における補強片21の左半部と右半部にはそれぞれ、2つの半円弧状刻設溝を左右方向で対向させて略円形となるように貫通して指挿入部22、22’を形成して指用孔23をなしている。   A finger hole 23 is formed in the front end fitting portion 2 of the front and rear cover bodies 10b and 10b '. Specifically, in the left half portion and the right half portion of the reinforcing piece 21 at the center portion of the grip portion 20, two semicircular engraved grooves are formed so as to face each other in the left-right direction so as to form a substantially circular shape. The finger insertion portions 22 and 22 ′ are formed to form finger holes 23.

また、先端合せ部2から前後カバー体10b、10b’にかけて二又に分岐した破断線40を刻設している。   Further, a bifurcated break line 40 is engraved from the front end fitting portion 2 to the front and rear cover bodies 10b and 10b '.

具体的には、前後カバー体10b、10b’の中央部で、図2及び図3に示すように下方拡開状に伸延形成した開封用の破断線40と、破断線40により囲まれた内側の開封部50と、を形成している。   Specifically, at the center of the front and rear cover bodies 10b and 10b ', as shown in FIGS. 2 and 3, an opening breaking line 40 extending downward and expanding, and the inside surrounded by the breaking line 40, are shown. And the unsealing portion 50 are formed.

前後カバー体10b、10b’における破断線40の伸延形状は、図3に示すように正面視において袋本体部10(包装袋A)の幅方向中央位置を縦断する中央縦断線C1を中心に左右対象となる下方拡開の山形状としている。   As shown in FIG. 3, the elongate shape of the breaking line 40 in the front and rear cover bodies 10b and 10b 'is right and left around a center vertical cutting line C1 which vertically crosses the widthwise center position of the bag body 10 (packaging bag A) in a front view. The target is a mountain shape with a downward expansion.

具体的には、破断線40は、拡開頂部40aを袋本体部10の中央縦断線C1上に位置づけるとともに、中央縦断線C1を中心に線対称となるように、拡開頂部40aからそれぞれ左右外方傾斜する2つの左右傾斜部40b、40b’と、左右傾斜部40b、40b’の終端で屈曲して袋本体部10の上下方向に沿う左右側部40c、40c’と、により構成している。   More specifically, the break line 40 is positioned on the central vertical section line C1 of the bag main body 10 at the expanded top section 40a, and is also symmetrical with respect to the central vertical section line C1 from the expanded top section 40a. It is constituted by two left and right inclined portions 40b and 40b 'that incline outward, and left and right side portions 40c and 40c' that are bent at the ends of the left and right inclined portions 40b and 40b 'and extend in the vertical direction of the bag body 10. I have.

このような破断線40の伸延形状は、下方拡開状であれば特に限定されることはなく、例えば、下方拡開する湾曲山形状や屈曲山形状、コ字形状、角形状であってもよい。なお、破断線40の左右側部40c、40c’の終端には裂け防止用の止穴を形成することとしてもよい。   The extension shape of the breaking line 40 is not particularly limited as long as it is a downwardly expanding shape. For example, a curved mountain shape, a bent mountain shape, a U-shaped shape, or a square shape that expands downward. Good. It should be noted that a stop hole for preventing tearing may be formed at the end of the left and right side portions 40c and 40c 'of the breaking line 40.

開封部50は、前後カバー体10b、10b’(袋本体部10の上部)の中央部において、その下端縁を前後カバー体10b、10b’と一体とし、それ以外の周縁を破断線40により囲まれた略山形状の部位であり、破断線40に沿って破断することにより取り出し用開口部の形成を可能としている。   The opening portion 50 has a lower end edge integrated with the front and rear cover members 10b and 10b 'at the center of the front and rear cover members 10b and 10b' (upper part of the bag body 10), and the other peripheral edge is surrounded by a break line 40. It is a substantially mountain-shaped portion that has been broken, and can be formed along the breaking line 40 to form a takeout opening.

また、開封部50は、袋本体部10に収納したロールペーパーRを取り出し可能な取り出し用開口部を形成できる面積で形成している。すなわち、開封部50の面積は、少なくともロールペーパーRの円柱形状における円面積よりも大きくなるようにしている。   The opening portion 50 has an area capable of forming a takeout opening through which the roll paper R stored in the bag body 10 can be taken out. That is, the area of the unsealing portion 50 is set to be at least larger than the circular area of the cylindrical shape of the roll paper R.

また、破断線40の拡開頂部40aは、図3乃至図5に示すように先端合せ部2においてシール部30を越えた把持部20の中央部の上下方向下部に配置している。   The expanded top portion 40a of the breaking line 40 is disposed vertically below the central portion of the grip portion 20 beyond the seal portion 30 in the front end fitting portion 2 as shown in FIGS.

換言すれば、開封部50は、頂部50aにシール部30の一部である頂部シール部30cを有するように構成している。   In other words, the unsealing portion 50 is configured to have a top seal portion 30c which is a part of the seal portion 30 on the top portion 50a.

このような構成により、把持部20を介して包装袋Aを持ち上げた際に、シール部30を境として下方の破断線40に不用意な荷重応力を伝えることなく開封部50の不用意な破断を防止している。   With such a configuration, when the packaging bag A is lifted via the grip portion 20, careless rupture of the opening portion 50 without transmitting inadvertent load stress to the breaking line 40 below the seal portion 30 is performed. Has been prevented.

なお、破断線40は、拡開頂部40aを前後カバー体10b、10b’内におさまるように形成すれば、袋本体部10の表裏における開封部50、50’同士が溶着連結しておらずフリー状態にあるため、包装袋Aの開封作業を容易にすることができる。   In addition, if the breaking line 40 is formed so that the expanded top portion 40a is contained within the front and rear cover members 10b and 10b ', the opening portions 50 and 50' on the front and back of the bag body 10 are not welded and connected to each other, and are free. Since it is in the state, the opening operation of the packaging bag A can be facilitated.

また、破断線40は、図5及び図6に示すように、各刻設溝41を円弧状又は山型状の拡開溝であって、同一方向に開口するように一定間隔を保持して連続して設けている。   Further, as shown in FIGS. 5 and 6, the breaking line 40 is an arc-shaped or chevron-shaped expanding groove for each engraving groove 41, and is maintained at a constant interval so as to open in the same direction. It is provided continuously.

すなわち、破断線40は、所定間隔を隔てて同一線上に配置され、同一方向に開口するように拡開状に貫通形成した複数の刻設溝41と、複数の刻設溝41同士の間に介在するつなぎ部分42と、を備える。   That is, the break lines 40 are arranged on the same line at a predetermined interval, and are formed between a plurality of engraving grooves 41 formed in an expanded shape so as to open in the same direction. And a connecting portion 42 interposed therebetween.

なお、つなぎ部分42の幅員D1は刻設溝41の幅員D2(刻設溝両端部の間を繋ぐ仮想弦線の長さ)の1〜1.5倍の長さとし、本実施形態ではつなぎ部分42の幅員D1を約4mm〜6mm、刻設溝41の幅員D2を約2mm〜4mmとしている。   The width D1 of the connecting portion 42 is 1 to 1.5 times the width D2 of the engraved groove 41 (the length of a virtual chord connecting between both ends of the engraved groove). The width D1 is about 4 mm to 6 mm, and the width D2 of the engraving groove 41 is about 2 mm to 4 mm.

また、拡開状の複数の刻設溝41は、図5及び図6に示すように袋本体部10上部の中央部においてそれぞれ、刻設溝の拡開両端部の間を繋ぐ仮想弦線を開封部50の仮想輪郭線M1上に配置するとともに拡開方向を開封部50の内側又は外側に向けて拡開するように形成している。   Further, as shown in FIGS. 5 and 6, the plurality of engraved grooves 41 each have an imaginary chord line connecting between the expanded ends of the engraved grooves at the center of the upper portion of the bag body 10. It is arranged on the virtual outline M <b> 1 of the unsealing part 50 and is formed so as to expand in the expanding direction toward the inside or outside of the unsealing part 50.

また、各刻設溝41は、図6に示すように隣接する刻設溝41、41’、、、の端部41a、41a’、、、から伸延形成される切込線43、43’が互いに交差合流するように拡開形成している。   As shown in FIG. 6, each of the engraving grooves 41 has a cutting line 43, 43 'extending from an end 41a, 41a' of an adjacent engraving groove 41, 41 '. The openings are formed so as to cross each other.

すなわち、各刻設溝41は、隣接する刻設溝41、41’、、、の端部41a、41a’の仮想延長直線(切込線43、43’)が互いに交差合流するように拡開している。   That is, each of the engraving grooves 41 is expanded so that the virtual extension straight lines (cut lines 43, 43 ') of the ends 41a, 41a' of the adjacent engraving grooves 41, 41 ',. are doing.

刻設溝41の形状は、円弧状又は山型状とすることにより刻設溝端部41a、41a’の伸延方向に沿ってつなぎ部分42に生起する切込線43同士が交差合流することを確実としている。なお、「円弧状」や「山型状」とは同形状における端部同士が互いに離反して外方拡開傾斜する形状を意図する。   The shape of the engraved groove 41 is formed in an arc shape or a mountain shape, so that the cut lines 43 generated in the connecting portion 42 along the extension direction of the engraved groove ends 41a, 41a 'are surely cross-flowed. And In addition, the term “arc-shaped” or “crest-shaped” refers to a shape in which ends of the same shape are separated from each other and outwardly inclined.

また、刻設溝41の内側には、図5及び図6に示すように円弧状又は略角形状のフラップ片44が形成されている。換言すれば、開封部50又は取り出し開口部の周縁には、複数の刻設溝41に応じて複数のフラップ片44が所定間隔を隔てて形成される。   5 and 6, an arc-shaped or substantially square-shaped flap piece 44 is formed inside the cut groove 41. As shown in FIG. In other words, a plurality of flap pieces 44 are formed at predetermined intervals on the periphery of the unsealing portion 50 or the take-out opening in accordance with the plurality of engraving grooves 41.

フラップ片44は、図7に示すように緊張したフィルム面の面方向に対して下側の押圧応力を負荷した際にフラップ片44の外側のフィルム面位置から変位して刻設溝端部41a、41a’に下方押圧応力を効果的に集中させる。   As shown in FIG. 7, the flap piece 44 is displaced from the film surface position outside the flap piece 44 when a downward pressing stress is applied to the surface direction of the tensioned film surface as shown in FIG. The downward pressing stress is effectively concentrated on 41a '.

その結果、つなぎ部分42に刻設溝41、41’の刻設溝端部41a、41a’の伸延方向を裂け方向とした「切込線」を生起することができ、隣接する刻設溝41、41’の端部41a、41a’から伸延してきた切込線同士が互いに交差合流することにより刻設溝同士の間に介在するつなぎ部分42を正確に裂断することができる。   As a result, it is possible to generate a “cut line” in the joint portion 42 in which the extension direction of the engraved groove ends 41a, 41a ′ of the engraved grooves 41, 41 ′ is a tearing direction, and the adjacent engraved groove 41, When the cut lines extending from the ends 41a, 41a 'of the 41' intersect with each other, the connecting portion 42 interposed between the engraved grooves can be accurately torn.

なお、破断線40の内側又は外側で、同破断線40と相似形の別の破断線を設けることにより、例えば2段、3段の破断線といった多段的な複数の破断線を形成することもできる。   In addition, by providing another break line similar to the break line 40 inside or outside the break line 40, it is also possible to form a multi-stage plural break line such as a two-stage or three-stage break line. it can.

すなわち、破断線40の内側及び/又は外側には、破断線40の輪郭形状に沿うように破断線40の複数の刻設溝41、41’の間且つ端部41a、41a’の伸延方向の先端位置に刻設溝を配置した他の破断線を設けることとしてもよい。   That is, on the inside and / or outside of the break line 40, between the plurality of engraved grooves 41, 41 ′ of the break line 40 and along the extension direction of the end portions 41 a, 41 a ′ along the contour shape of the break line 40. Another breaking line in which the engraving groove is arranged at the tip position may be provided.

具体的には、破断線40における隣接刻設溝41、41’、、、の端部41a、41a’から伸延する仮想延長直線(切込線43、43’)上に、刻設溝を配置する破断線40の内側又は外側で他の破断線を形成する。なお、他の破断線を構成する刻設溝の形状は特に限定されることはなく、線状、円弧状であってもよい。   Specifically, the engraved grooves are arranged on virtual extension straight lines (cut lines 43, 43 ') extending from the ends 41a, 41a' of the adjacent engraved grooves 41, 41 ',. Another break line is formed inside or outside the break line 40 to be formed. It should be noted that the shape of the engraved groove forming another break line is not particularly limited, and may be linear or arcuate.

このような構成により破断線40の刻設溝41、41’、、、の端部41a、41a’から伸延してきた切込線が他の破断線の刻設溝で合流するため、他の破断線における刻設溝が切込線同士の交差合流の補助線として機能し、破断線40の刻設溝41、41’同士の間に介在するつなぎ部分42の裂断を確実に行うことができる。   With such a configuration, the cut lines extending from the end portions 41a, 41a 'of the cut grooves 41, 41' of the break line 40 merge at the cut grooves of the other break lines. The cut groove in the line functions as an auxiliary line for the intersection and merging of the cut lines, and it is possible to surely break the joint portion 42 interposed between the cut grooves 41 and 41 ′ of the break line 40. .

次に、包装袋Aの製造方法の一例について簡単に説明する。まず、ビニール筒体1を繰り出しながら、これに一定間隔ごとに破断線カッタにより破断線40を形成する。   Next, an example of a method for manufacturing the packaging bag A will be briefly described. First, a break line 40 is formed on the vinyl cylinder 1 at regular intervals by a break line cutter while the vinyl cylinder 1 is being fed.

補強片21となる帯状ロールフイルムをビニール筒体1の中央部分に重なるようにシール機まで延長させ、該シール機によって各シール部30、31、、、を形成するとともに帯状ロールフイルムから補強片21を切断することで把持部20を形成する。   The strip-shaped roll film serving as the reinforcing piece 21 is extended to the sealing machine so as to overlap the central portion of the vinyl cylinder 1, and the sealing machines form the respective seal portions 30, 31,. Is cut to form the gripping portion 20.

このようなビニール筒体1が、最終的にロールペーパーRを収納して袋本体部10の下部開口を折り畳み閉塞できる所定長さで切断されることにより包装袋Aとなる。   Such a vinyl tubular body 1 is finally cut into a predetermined length capable of storing the roll paper R and folding and closing the lower opening of the bag body 10 to form the packaging bag A.

次に、包装袋Aへのロールペーパー収納方法について説明する。図8及び図9は、包装袋Aにロールペーパーを収納する過程を示す説明図である。   Next, a method of storing roll paper in the packaging bag A will be described. 8 and 9 are explanatory diagrams showing a process of storing roll paper in the packaging bag A.

包装袋Aには、図8に示すように複数のロールペーパーRを並列段組した略方形状のロールペーパー群R1が、袋本体部10の下部開口10cから袋本体部10内部へ、各ロールペーパーRの筒軸方向を袋本体部10の長手方向に沿うように押し込み内挿される。   As shown in FIG. 8, the packaging bag A has a substantially rectangular roll paper group R1 formed by arranging a plurality of roll papers R in parallel, from the lower opening 10c of the bag body 10 to the inside of the bag body 10. The paper R is inserted by being pushed in such a manner that the cylindrical axis direction of the paper R is along the longitudinal direction of the bag body 10.

なお、本実施形態で包装袋Aに収納するロールペーパー群R1は、袋本体部10の幅方向に2個、奥行き方向に2個、長手方向に3個の合計12個のロールペーパーRにより方形状に構成している。   In this embodiment, the roll paper group R1 stored in the packaging bag A is composed of two roll papers R, two in the width direction of the bag body 10, two in the depth direction, and three in the longitudinal direction. It has a shape.

ロールペーパー群R1は、図1で示したようにその先端外周縁が袋本体部10上端面を構成する左右の三角形折込部3、3’に突き当たるまで、袋本体部10内部に進入させる。   As shown in FIG. 1, the roll paper group R <b> 1 is made to enter the inside of the bag main body 10 until the outer peripheral edge of the roll paper abuts the left and right triangular folds 3 and 3 ′ constituting the upper end surface of the bag main body 10.

このロールペーパー群R1の進入に伴い、扁平状の袋本体部10は、左右のガゼット1a、1a’を押し広げられて、袋本体部10内部に空気を流入させることになる。   As the roll paper group R1 enters, the flat bag main body 10 is pushed and spread out the left and right gussets 1a and 1a ', and air flows into the bag main body 10.

かかる流入空気は、ロールペーパー群R1先端面により袋本体部10上部まで移動し、袋本体部10の各シール部30、31、、、の複数の通気孔30b、31b、、、により外部へ排気される。   The inflow air moves to the upper portion of the bag main body 10 by the front end face of the roll paper group R1, and is exhausted to the outside through the plurality of ventilation holes 30b, 31b, of the seal portions 30, 31,. Is done.

すなわち、各シール部30、31、、、の通気孔30b、31b、、、により流入空気を排気することで袋本体部10内部で圧縮空気が形成されることを抑制し、圧縮空気による袋本体部10の内側からのシール部30及び破断線40の破損を防止可能としている。   In other words, by suppressing the formation of compressed air inside the bag body 10 by exhausting the inflow air through the ventilation holes 30b, 31b, of the respective seal portions 30, 31,. The breakage of the seal portion 30 and the break line 40 from inside the portion 10 can be prevented.

このようにロールペーパー群R1が内挿された袋本体部10が、その下部開口10cを溶着閉塞することにより、図1に示したロールペーパーRを収納した包装袋Aとなる。   The bag main body 10 in which the roll paper group R1 is inserted as described above becomes a packaging bag A containing the roll paper R shown in FIG. 1 by welding and closing the lower opening 10c.

次に、ロールペーパーRを収納した状態の包装袋Aの開封方法について説明する。図10乃至図13は、ロールペーパーRを収納した状態の包装袋Aにおける開封過程を示す説明図である。   Next, a method of opening the packaging bag A in which the roll paper R is stored will be described. FIG. 10 to FIG. 13 are explanatory views showing the opening process of the packaging bag A in which the roll paper R is stored.

まず、未開封状態の包装袋Aを床面に載置立設させ、先端合せ部2の把持部20を上方に引っ張り上げ、その下方の前後カバー体10b、10b’にテンションをかけて前後カバー体10b、10b’を緊張変態させる。   First, the unopened packaging bag A is placed and erected on the floor surface, the grip portion 20 of the front end fitting portion 2 is pulled upward, and tension is applied to the front and rear cover members 10b and 10b 'below the front and rear cover members. The body 10b, 10b 'is nervous.

このような前後カバー体10b、10b’の緊張変態状態において、ロールペーパー群R1の上方には袋本体部10の上部周壁、すなわち略三角形折込部3、3’と前カバー体10b及び後カバー体10b’とによりなす略三角柱形状の内部空間Sが形成される。   In such a tensioned state of the front and rear cover bodies 10b and 10b ', the upper peripheral wall of the bag body 10, that is, the substantially triangular folded portions 3, 3', the front cover body 10b, and the rear cover body are provided above the roll paper group R1. 10b 'forms a substantially triangular prism-shaped internal space S formed by the inner space S.

この内部空間Sは、開封部50を袋本体部10の外側から内側に押し込み破断するための余裕空間として機能し、袋本体部10上部の周壁フィルムの緊張に伴って図3及び図4で示したように各シール部30、31、、、の通気孔30b、31b、、、により袋本体部10の外部から取り込まれた空気により形成する。   This internal space S functions as a spare space for pushing the opening portion 50 inward from the outside of the bag main body 10 and breaking it, and is shown in FIGS. 3 and 4 with the tension of the peripheral wall film on the upper part of the bag main body 10. As described above, the air holes 30 b, 31 b, of the seal portions 30, 31, are formed by air taken in from the outside of the bag body 10.

次いで、図11に示すように前後カバー体10b、10b’の緊張変態状態で前後カバー体10b、10b’面を手掌で押圧することにより刻設溝41、41’、、、を介して破断する。   Then, as shown in FIG. 11, the front and rear cover bodies 10b and 10b 'are pressed by the palms of the front and rear cover bodies 10b and 10b' in the tensioned state of the front and rear cover bodies 10b and 10b 'to break through the engraved grooves 41 and 41'. .

具体的には、開封部50を掌面等で内部空間Sに向けて下方傾斜するように押し込み、前後カバー体10b、10b’中央部で破断する。   Specifically, the unsealing portion 50 is pushed in such a manner as to incline downward on the palm surface or the like toward the internal space S, and is broken at the center of the front and rear cover bodies 10b and 10b '.

開封部50に付与された下方押圧力に応じて破断線40(開封部50の周縁)のフラップ片44が、図7で示したようにその両端のつなぎ部分42を支点に袋面の上下方向に変位する。   In accordance with the downward pressing force applied to the opening portion 50, the flap pieces 44 of the breaking line 40 (peripheral edge of the opening portion 50) are, as shown in FIG. Is displaced.

この際、刻設溝端部41a(つなぎ部分42始端)に押圧応力が集中して、刻設溝端部41aの伸延方向に沿った切込線43が生起する。   At this time, the pressing stress concentrates on the cut groove end 41a (the start end of the joint portion 42), and a cut line 43 is generated along the extension direction of the cut groove end 41a.

さらに開封部50を内部空間S側へ押し込むと、刻設溝端部41aからの切込線43が伸長し、図6で示したように隣接する刻設溝41、41’、、、の刻設溝端部41a、41a’、、、からそれぞれ伸長してきた切込線43、43’、、、同士が合流し、図12に示すようにそれぞれの刻設溝41、41’、、、同士の間に介在するつなぎ部分42を裂断する。   When the opening portion 50 is further pushed into the internal space S side, the cut line 43 from the engraved groove end 41a is elongated, and as shown in FIG. 6, the engraved grooves 41, 41 'are formed. The cutting lines 43, 43 ', extending from the groove ends 41a, 41a', respectively, merge with each other, and as shown in FIG. 12, between the engraved grooves 41, 41 ',. Is cut off at the connecting portion 42 interposed between them.

なお、正面側の開封部50は、背面側の開封部50’と頂部シール部30cを介して連結しているが、この押し込み開封作業時の下方傾斜の応力を受けて背面側の開封部50’の頂部から離れる。   The front opening portion 50 is connected to the rear opening portion 50 ′ via the top seal portion 30c. However, the front opening portion 50 receives the stress of the downward inclination during the push-in opening operation, and the rear opening portion 50 ′. 'Leave from the top.

このようにして開封部50を、図12に示すよう破断線40に沿って完全に破断し、最終的に、図13に示すように前後カバー体10b、10b’の中央位置にロールペーパーRの取り出し用開口部60が形成した包装袋Aの開封形態とする。   In this manner, the opening portion 50 is completely broken along the breaking line 40 as shown in FIG. 12, and finally, the roll paper R is positioned at the center of the front and rear cover bodies 10b and 10b 'as shown in FIG. It is assumed that the packaging bag A formed with the opening 60 for taking out is opened.

この開封形態の包装袋Aにおいて、開封部50の外周縁や取り出し用開口部60の内周縁にはフラップ片44やつなぎ部分42が残ることとなり、図13に示すように開封部50の外周縁や取り出し用開口部60の内周縁は破断線40の裂断形状に由来するギザギザの凹凸状となる。   In this openable packaging bag A, the flap pieces 44 and the connecting portion 42 remain on the outer peripheral edge of the unsealing portion 50 and the inner peripheral edge of the take-out opening 60, and as shown in FIG. In addition, the inner peripheral edge of the take-out opening 60 has a jagged uneven shape derived from the cut shape of the break line 40.

このように本実施形態に係る包装袋Aによれば、袋本体部10上部において開封部50をワンタッチで押し込み破断して取り出し用開口部60を形成でき、包装袋Aの開封作業を簡単にすることができる。なお、この開封部50を袋本体部10の外部へ引っ張り上げた際にも、袋本体部10上部に取り出し用開口部60を形成できることは勿論である。   As described above, according to the packaging bag A according to the present embodiment, the opening portion 50 can be formed by pushing the opening portion 50 at the upper portion of the bag main body 10 with a single touch and breaking the opening portion 60, thereby simplifying the opening operation of the packaging bag A. be able to. In addition, even when the opening portion 50 is pulled up to the outside of the bag main body portion 10, it is needless to say that the opening 60 for taking out can be formed in the upper portion of the bag main body portion 10.

すなわち、フィルムの面方向に直交する応力を負荷した場合であっても、開封部50や袋本体部10に「無用な裂け」を生起させることなく破断線40に沿って開封部50を正しく破断して包装袋Aの破損を可及的防止するとともに袋本体部10上部に小口の取り出し用開口部60を正しく形成することができる。   That is, even when a stress perpendicular to the plane direction of the film is applied, the opening portion 50 is correctly broken along the breaking line 40 without causing “unnecessary tearing” in the opening portion 50 or the bag body 10. As a result, the packaging bag A can be prevented from being damaged as much as possible, and the opening 60 for taking out the fore edge can be correctly formed in the upper portion of the bag main body 10.

しかも、開封形態の包装袋Aにおいて、開封部50は袋本体部10と下端縁で一体となっていることから、取り出し用開口部60を閉塞して未使用状態の残りのロールペーパーの埃よけを可能とするする蓋体として機能する。   Moreover, in the unsealed packaging bag A, the unsealing portion 50 is integrated with the bag body 10 at the lower end edge, so that the opening 60 for taking out is closed to remove dust from the remaining unused roll paper. It functions as a cover that allows for protection.

特に、開封部50の外周縁や取り出し用開口部60の内周縁のギザギザの凹凸状を形成するフラップ片44やつなぎ部分42同士が互いにズレて重なりあうことで、取り出し用開口部60に開封部50が掛合し、取り出し用開口部60の閉塞を可能とする。   In particular, the flap pieces 44 and the connecting portions 42 forming the jagged irregularities on the outer peripheral edge of the opening portion 50 and the inner peripheral edge of the opening portion 60 are shifted from each other and overlap each other. 50 engages to allow the removal opening 60 to be closed.

さらには、上記破断線40により包装袋Aの破損を防止しつつ破断箇所を開封部50に限定していることから、袋本体部10の収納機能を確実に保持することができ、ロールペーパーRを全て取り出した後には包装袋Aをゴミ袋等の袋体として転用することができる。   Further, since the break point is limited to the unsealing portion 50 while preventing the packaging bag A from being broken by the break line 40, the storage function of the bag body portion 10 can be reliably held, and the roll paper R Can be diverted as a bag such as a garbage bag.

Next, a packaging bag B according to a second embodiment will be described. FIG. 14 is an enlarged front view showing the packaging bag according to the present embodiment, FIG. 15 is a cross-sectional view taken along the line A-A of the gripper according to the present embodiment, and FIGS. 16 and 17 show an opening form of the packaging bag according to the present embodiment. FIG. In addition, below, about the structure similar to the above-mentioned packaging bag A, the same code | symbol is attached | subjected and description is abbreviate | omitted.

本実施形態に係る包装袋Bは、図14に示すように把持部20の第2の破断線と袋本体部10の破断線とを包装袋Dの上部で組み合わせてなる仮想裂断線が正面視略逆Y字形状となるように形成している。   In the packaging bag B according to the present embodiment, as shown in FIG. 14, a virtual tear line formed by combining the second break line of the gripper 20 and the break line of the bag body 10 at the top of the packaging bag D is viewed from the front. It is formed so as to have a substantially inverted Y-shape.

包装袋Bは、包装袋Aと異なり、把持部20の幅方向中央位置で把持部20を縦断するための第2の破断線70を形成している。   The packaging bag B, unlike the packaging bag A, forms a second break line 70 for vertically cutting the grip portion 20 at the center position in the width direction of the grip portion 20.

すなわち、把持部20には、把持部20の上縁から下方向に伸延し、その先端で開封用の破断線40の拡開頂部40aと連結する点状又は直線状の複数の刻設溝からなる第2の破断線70を形成している。   In other words, the gripping portion 20 extends from the upper edge of the gripping portion 20 in a downward direction, and a plurality of point-shaped or linear engraved grooves connected to the expanded top portion 40a of the breaking line 40 for opening at the tip thereof. A second break line 70 is formed.

なお、第2の破断線70はビニール筒体1の上部表裏面を貫通するように形成し、第2の破断線70と連結する破断線40の拡開頂部40aは下方拡開する幅広の半円弧状刻設溝80として形成している。   The second break line 70 is formed so as to penetrate the upper and lower surfaces of the vinyl cylinder 1, and the expanded top 40 a of the break line 40 connected to the second break line 70 has a wide half that expands downward. It is formed as an arc-shaped engraving groove 80.

さらに、把持部20に設けられた補強片21には、補強片21の上縁から下方向に伸延し、その先端で破断線40の拡開頂部40aと連結する点状又は直線状の複数の刻設溝からなる第3の破断線71が設けられている。   Further, the reinforcing piece 21 provided on the grip portion 20 has a plurality of point-like or straight-like pieces extending downward from the upper edge of the reinforcing piece 21 and connected to the expanded top 40a of the breaking line 40 at the tip. A third break line 71 composed of an engraved groove is provided.

しかも、把持部20の第2の破断線70と補強片21の第3の破断線71とは、図15に示すように互いに左右方向にずらして形成している。   Moreover, the second breaking line 70 of the grip 20 and the third breaking line 71 of the reinforcing piece 21 are formed so as to be shifted from each other in the left-right direction as shown in FIG.

すなわち、2つの破断線70、71は、把持部20の中央縦断線C1を中心に互いに左右近傍位置で縦方向に伸延形成し、持ち運び時に加わる引っ張り荷重を分散させて不用意な把持部20の左右分離を防止している。   That is, the two break lines 70 and 71 are formed to extend vertically in the vicinity of the left and right sides around the central longitudinal line C1 of the gripper 20 and disperse the tensile load applied when being carried. Left and right separation is prevented.

かかる構成の包装袋Bは、ロールペーパーRを取り出すに際し、破断線40と第2の破断線70及び第3の破断線71を切り開くものであり、補強片21を含めて把持部20が左右分離するとともに、これに連続して袋本体部10上部の破断線40に切込みを形成する。   The packaging bag B having such a configuration cuts the breaking line 40, the second breaking line 70, and the third breaking line 71 when the roll paper R is taken out, and the gripping portion 20 including the reinforcing piece 21 is separated into right and left. At the same time, a cut is formed in the break line 40 on the upper part of the bag body 10 continuously.

すなわち、把持部20の両端部を引っ張ると、第2の破断線70及び第3の破断線71に沿って把持部20が、図16に示すように左右把持部片24、24’に分離するとともに前後カバー体10b、10b’が左右上壁片10d、10d’として分離し、袋本体部10の左右側に小口の取り出し用開口部61、61’を形成できる。   That is, when the both ends of the gripper 20 are pulled, the gripper 20 separates into the left and right gripper pieces 24 and 24 ′ as shown in FIG. 16 along the second break line 70 and the third break line 71. At the same time, the front and rear cover bodies 10b and 10b 'are separated as left and right upper wall pieces 10d and 10d', so that small opening openings 61 and 61 'can be formed on the left and right sides of the bag body 10.

具体的には、把持部20の第2の破断線70及び第3の破断線71を裂断していくと、その先端の破断線40の拡開頂部40aに相当する半円弧状刻設溝80に突き当たり、同刻設溝80の左右端で伸延する破断線40の左右傾斜部40bに沿った裂断が連続的に行われる。   Specifically, when the second break line 70 and the third break line 71 of the grip portion 20 are torn, a semi-arc-shaped engraved groove corresponding to the expanded top portion 40a of the break line 40 at the tip end. The breaking line 40 extending at the left and right ends of the engraved groove 80 at the right and left ends of the groove 80 is continuously broken along the left and right inclined portions 40b.

この際、袋本体部10の表裏2つの開封部50、50’は頂部シール部30cを介して連結状態にあるため、開封部50、50’を袋本体部10上部の中央で残しつつ、開封部50の左右側の袋本体部10のフィルムが左右上壁片10d、10d’として分離する。   At this time, since the two front and rear unsealing portions 50 and 50 ′ of the bag body 10 are connected via the top seal portion 30 c, the unsealing portions 50 and 50 ′ are opened at the center of the upper portion of the bag body 10 while being opened. The films of the bag body 10 on the left and right sides of the part 50 are separated as left and right upper wall pieces 10d and 10d '.

その結果、前後カバー体10b、10b’の左右側に、図16に示すように小口の取り出し用開口部61、61’を形成することができる。   As a result, as shown in FIG. 16, the small opening portions 61 and 61 'can be formed on the left and right sides of the front and rear cover bodies 10b and 10b'.

また、頂部シール部30cを介して連結した表裏の開封部50、50’は、袋本体部10に収納したロールペーパーR上面に効果的に覆いかぶさり、ロールペーパーRを全部取り出してしまうまでの保管時の埃除けとして機能する。   Further, the front and back opening portions 50 and 50 ′ connected via the top seal portion 30 c effectively cover over the upper surface of the roll paper R stored in the bag body 10, and are stored until the entire roll paper R is taken out. Functions as a dust remover.

このような構成により、包装袋Cの開封作業をした際には、袋本体部10の開封部50、50’やその上方の把持部20中央部を中央位置に残して、把持部20の第2の破断線73、73’に連なるように袋本体部10における破断線80の左右側部80b、80b’を裂断し、袋本体部10上部の両側に小口の取り出し用開口部61、61’を2つ形成することができる。   With such a configuration, when the packaging bag C is opened, the opening portions 50 and 50 ′ of the bag body 10 and the central portion of the gripping portion 20 above the bagging portion 20 are left at the center position, and the The right and left side portions 80b, 80b 'of the break line 80 in the bag body 10 are torn so as to be continuous with the break lines 73, 73' of FIG. 'Can be formed twice.

また、把持部20の一部を開封部50から破断線80の水平部80aで切り離すことにより、簡単に大口の取り出し用開口部62を形成することができる。   In addition, a large opening 62 can be easily formed by separating a part of the grip 20 from the opening 50 at the horizontal portion 80a of the breaking line 80.

〔第4の実施形態〕
次に、第4の実施形態に係る包装袋Eについて説明する。図19は本実施形態に係る包装袋を示す拡大正面図である。
[Fourth embodiment]
Next, a packaging bag E according to a fourth embodiment will be described. FIG. 19 is an enlarged front view showing the packaging bag according to the present embodiment.

本実施形態に係る包装袋Dは、図19に示すように把持部20の第2の破断線と袋本体部10の破断線とを包装袋Dの上部で組み合わせてなる仮想裂断線が正面視三角形状となるように形成している。   As shown in FIG. 19, the packaging bag D according to the present embodiment has a virtual tear line formed by combining the second breaking line of the gripper 20 and the breaking line of the bag body 10 at the top of the packaging bag D as viewed from the front. It is formed so as to have a triangular shape.

具体的には、2つの第2の破断線73、73’は、指挿入部22、22’よりも内側で把持部20の上縁中央から互いに左右外方へ傾斜するようにシール部30を越えて、前後カバー体10b、10b’中途部まで伸延するように形成している。   Specifically, the two second breaking lines 73 and 73 'are arranged such that the seal portions 30 are inclined to the right and left outward from the center of the upper edge of the grip portion 20 inside the finger insertion portions 22 and 22'. The front and rear cover members 10b and 10b 'are formed so as to extend to the middle part.

また、袋本体部10の破断線81は、正面視で下方拡開の台形状に形成しており、左右外方に向けて傾斜する左右傾斜側部81b、81b’と、左右側部81b、81b’の始端同士の間で左右伸延する水平部81aとにより構成している。   In addition, the break line 81 of the bag body 10 is formed in a trapezoidal shape that expands downward as viewed from the front, and includes left and right inclined side portions 81b and 81b ′ that are inclined left and right outward, and left and right side portions 81b and 81b.

すなわち、第2の破断線73、73’と破断線80の左右側部81b、81b’とが、把持部20や袋本体部10で同一線上で連結するように構成している。   That is, the second break lines 73 and 73 ′ and the left and right side portions 81 b and 81 b ′ of the break line 80 are connected to each other on the same line by the grip 20 and the bag body 10.

このような構成により、包装袋Eの開封作業をした際には、包装袋Dと同様に、袋本体部10の開封部50、50’やその上方の把持部20中央部を中央位置に残して、把持部20の第2の破断線73、73’に連なるように袋本体部10における破断線81の左右側部81b、81b’を裂断し、図16に示したように袋本体部10上部の両側に小口の取り出し用開口部61、61’を2つ形成することができる。   With such a configuration, when the packaging bag E is opened, similarly to the packaging bag D, the opening portions 50 and 50 ′ of the bag body 10 and the central portion of the grip portion 20 above the bag body 10 are left at the central position. Then, the left and right sides 81b and 81b 'of the break line 81 in the bag body 10 are torn so as to be continuous with the second break lines 73 and 73' of the grip portion 20, and as shown in FIG. Two small opening portions 61, 61 'can be formed on both sides of the upper portion of the upper portion 10.

また、把持部20の一部を開封部50から破断線81の水平部81aで切り離すことにより、図17に示したように簡単に大口の取り出し用開口部62を形成することができる。   In addition, by separating a part of the gripping portion 20 from the opening portion 50 by the horizontal portion 81a of the breaking line 81, the large opening 62 can be easily formed as shown in FIG.

また、把持部20の指挿入部22、22’を貫通して把持した際には、その内側の2つの第2の破断線73、73’を手掌内に握り込んで把持することとなるため、同第2の破断線73、73’に不用意な引っ張り応力を負荷することなく、持ち運び時の把持部20の不用意な破断を防止することができる効果がある。   In addition, when the gripper 20 is gripped by penetrating the finger insertion portions 22 and 22 ′, the two second break lines 73 and 73 ′ inside the gripper 20 are gripped in the palm. Thus, there is an effect that it is possible to prevent the gripping portion 20 from being inadvertently broken during carrying without applying careless tensile stress to the second breaking lines 73 and 73 '.

以上、説明してきたように、本発明に係るロールペーパー用包装袋によれば、「無用な裂け」を生起させることなく破断線の伸延方向に沿って開封部を正しく破断して袋本体部上部に取り出し用の開口部を形成することができ、包装袋の開封作業を簡単に行うことができ、開封後には収納している未使用のロールペーパーの保管状態を良好にすることができる。   As described above, according to the roll paper packaging bag according to the present invention, the opening portion is correctly broken along the extension direction of the breaking line without causing “unnecessary tearing” and the upper portion of the bag body portion An opening for taking out can be formed in the opening, the opening operation of the packaging bag can be easily performed, and the stored state of unused roll paper can be improved after opening.

すなわち、本発明によれば、略方形状に保形したビニール筒体の上部開口端縁において、筒体開口端左右に略三角形折込部を形成して、この略三角形折込部上に重複する状態で先端部合せ溶着形状の前後カバー体を折曲形成し、しかも前後カバー体は、先端合せ部を引上げ緊張した際に傾斜状に緊張変態すべく構成し、また、前後カバー体の先端合せ部には、指用孔を形成し、先端合せ部から前後カバー体にかけて二又に分岐した破断線を刻設し、破断線は、各刻設溝を円弧状又は山型状の拡開溝に形成して、かつ一定間隔で連続して設け、前後カバー体の緊張変態した状態で前後カバー体面を手掌で押圧することにより刻設溝を介して破断可能に構成したため、袋面の面方向の直交する上下方向の応力をかけた際には、拡開状の刻設溝に囲まれた内側のフラップ片を袋面の上下方向にせり出し変位させて刻設溝端部に応力を効果的に集中させることができる。   That is, according to the present invention, a substantially triangular fold is formed on the left and right ends of the cylindrical opening at the upper opening edge of the substantially cylindrically shaped vinyl cylindrical body, and the vinyl triangular fold overlaps the substantially triangular fold. The front and rear cover body is bent to form a welded shape at the tip end, and the front and rear cover body is configured to be inclined and transformed when the front end is pulled up and tensioned. The finger hole is formed, and a break line is bifurcated from the front end fitting part to the front and rear cover body, and the break line is formed by turning each engraved groove into an arc-shaped or mountain-shaped expanded groove. Formed and provided continuously at a constant interval, the front and rear cover body is configured to be ruptured through the engraved groove by pressing the front and rear cover body surface with the palm in a state of tension transformation, so that the bag surface surface direction When perpendicular vertical stress is applied, it is surrounded by The inner flap pieces can be concentrated stresses in time 設溝 end by protruding vertically displaced in the bag surfaces effectively.

その結果、つなぎ部分に刻設溝の拡開端部伸延方向を裂け方向とした「切込線」を生起することができ、隣接する刻設溝端部から伸延する切込線同士が互いに交差合流することにより刻設溝同士の間に介在するつなぎ部分を正確に裂断することができる。   As a result, it is possible to generate a “cut line” in which the extension direction of the engraved groove extends in the joining portion at the extending end direction, and the cut lines extending from the adjacent engraved groove ends cross each other. As a result, the connecting portion interposed between the engraved grooves can be accurately torn.

すなわち、袋面の面方向に沿う応力を負荷した場合だけなく面方向に直交する応力を負荷した場合にも、包装袋に「無用な裂け」を生起させることなく破断線の伸延方向に沿って開封部を正しく破断して袋上面にロールペーパーの取り出し用の開口部を形成することができ、包装袋の開封作業を簡単に行うことができ、開封後には収納している未使用のロールペーパーの保管状態を良好にすることができる効果がある。   That is, not only when a stress is applied along the plane direction of the bag surface but also when a stress perpendicular to the plane direction is applied, along the extension direction of the breaking line without causing `` useless tearing '' to the packaging bag. The opening part can be cut off correctly to form an opening for taking out the roll paper on the top of the bag, making it easy to open the packaging bag. This has the effect of improving the storage state of the device.
