Description

本発明は、特に食品包装用のラップフィルム、アルミホイル、クッキングシート等(以下、ラップフィルムと称す)を巻回したラップフィルム収納箱の開封片に関する。   The present invention particularly relates to an opening piece of a wrap film storage box in which a wrap film for food packaging, an aluminum foil, a cooking sheet or the like (hereinafter referred to as a wrap film) is wound.

ラップフィルムは、通常、紙製の芯体に巻回された巻筒体が、紙製の直方体の箱に収納されており、糊材等でラップフィルム収納箱の前板部分に接着されている開封片8を剥すことで、ラップフィルムの使用に先立ち蓋の開閉が可能になる。ラップフィルムの切断手段としては金属、紙、樹脂製の鋸刃が知られており、上記鋸刃は掩蓋片6の先端部に配置されるのが一般的であるが、底板2の前板1側縁部、前板1の上縁に配置される場合もある。
従来のラップフィルム収納箱に設けられている開封片は、大部分が図4に示した横J型の切り取り線からなり、一方の方向(図4においては右側から左側へ)からのみ開封できる形状となっている。これを他方(図4においては左側から右側へ)から開封片を剥そうとすると、開封片がきれいに剥がれず、剥している途中で開封片がちぎれるといった問題が発生する。これらの開封片には、開封片を剥す方向が矢印等で表示されているものの、ラップフィルム使用者の利き手によっては非常に開封しにくく、開封片に対して左右どちらの方向からも開封片をスムーズに剥せることが望ましい。
A wrap film is usually a wound cylindrical body wound around a paper core, and is stored in a rectangular box made of paper, and is adhered to the front plate portion of the wrap film storage box with glue or the like. By peeling off the opening piece 8, the lid can be opened and closed prior to use of the wrap film. As a wrap film cutting means, a metal, paper, or resin saw blade is known, and the saw blade is generally disposed at the tip of the lid cover piece 6, but the front plate 1 of the bottom plate 2 is used. In some cases, the side edges may be disposed on the upper edge of the front plate 1.
The opening piece provided in the conventional wrap film storage box is mostly composed of a horizontal J-shaped cut line shown in FIG. 4, and can be opened only from one direction (from right to left in FIG. 4). It has become. If the opening piece is peeled off from the other side (from the left side to the right side in FIG. 4), the opening piece is not peeled off properly, and the opening piece is torn off while being peeled off. Although the direction to peel off the opening piece is indicated by an arrow etc. on these opening pieces, it is very difficult to open depending on the dominant hand of the wrap film user, and the opening piece is removed from either the left or right direction with respect to the opening piece. It is desirable to remove it smoothly.

これに対して、どちらの方向からも剥すことが可能である開封片を備えたラップフィルム収納紙箱として切取り線に図3に示した切れ目を採用し、開封片を剥す際の引き裂きが必ず次の切れ目の屈曲した左端部または右端部に捕まって、断続的な切れ目線を次々に確実に左方又は右方から引き裂いて切断することができると開示されている(特許文献1)。しかしながら、開示されている切れ目形状では引き裂きが必ず次の切れ目に捕まるとは言い難く、開封方向、すなわち開封片の引っ張り方向がやや掩蓋片寄りになった場合、掩蓋片の板紙に層間剥離が発生し、外観が悪化する場合がある。また、開封方向がやや底板寄りになった場合、開封片が開封動作の途中でちぎれてしまう場合がある。しかしながら、このようなトラブルは切れ目間の距離を短くする、すなわち掩蓋片と開封片のつなぎ部の長さを短くすることで回避できると推測される。   On the other hand, the cut shown in FIG. 3 is used as a wrap film storage paper box with an open piece that can be peeled from either direction, and the tear when the open piece is peeled is always the following. It is disclosed that an intermittent cut line can be surely torn and cut from the left side or the right side one after another by catching at the bent left end or right end (Patent Document 1). However, with the disclosed cut shape, it is difficult to say that the tear always catches the next cut, and if the opening direction, that is, the pulling direction of the opened piece is slightly closer to the lid piece, delamination occurs on the paperboard of the lid piece In addition, the appearance may deteriorate. Further, when the opening direction is slightly closer to the bottom plate, the opening piece may be broken during the opening operation. However, it is assumed that such trouble can be avoided by shortening the distance between the cuts, that is, by shortening the length of the connecting portion between the lid cover piece and the opening piece.

一方で、一般的なラップフィルム収納箱は、適度な厚みを持つコートボール紙を木型により図1のような展開状態(カートンブランク)に打ち抜き、その後鋸刃を装着する工程を経る。ラップフィルム収納箱で用いられている鋸刃の多くは金属製であり、金型で適度な厚みの金属板を鋸刃形状に打ち抜くと同時に、カシメによって図1の状態に形成されたカートンブランクに装着される。この工程において、鋸刃を所定の位置に装着させるため、生産ラインを流れてきたカートンブランクを鋸刃装着工程のところで一旦ストッパーに開封片の端8’を衝突させることで、強制的に停止させる方法が主流である。   On the other hand, a general wrap film storage box is subjected to a process of punching coated cardboard having an appropriate thickness into a developed state (carton blank) as shown in FIG. Most of the saw blades used in the wrap film storage box are made of metal, and at the same time as punching a metal plate of an appropriate thickness into a saw blade shape with a die, the carton blank formed in the state of FIG. 1 by caulking Installed. In this process, in order to mount the saw blade at a predetermined position, the carton blank flowing through the production line is forcibly stopped by causing the end 8 'of the opening piece to collide with the stopper once in the saw blade mounting process. The method is mainstream.

図1に示したカートンブランクの切り取り線7に特許文献1で開示された切れ目を付与した場合、隣合う切れ目の端部を結ぶ仮想線がカートンブランクの長手方向と水平であるため、つなぎ部の長さにも影響されるが、鋸刃装着工程のストッパーに開封片の端8’が衝突した際に各切れ目間のつなぎ部の配置位置に沿って開封片8が折れ曲がりが発生する可能性があるため、鋸刃の装着位置がずれて鋸刃の刃先の突出不足が発生したり、鋸刃が斜めに装着されたりする可能性がある。さらに、開封性に優れたどちらの方向からも開封可能な開封片を実現するために、前述のように切れ目間の距離、すなわちつなぎ部の長さを短くした場合は、つなぎ部の強度が弱くなるためストッパーに開封片の端8’が衝突した際に、つなぎ部においてちぎれが発生する可能性がある。   When the cut line disclosed in Patent Document 1 is given to the cut line 7 of the carton blank shown in FIG. 1, the imaginary line connecting the ends of the adjacent cuts is horizontal with the longitudinal direction of the carton blank. Although it is influenced by the length, there is a possibility that the opening piece 8 is bent along the arrangement position of the connecting portion between the cuts when the end 8 'of the opening piece collides with the stopper of the saw blade mounting process. For this reason, there is a possibility that the mounting position of the saw blade is shifted and the cutting edge of the saw blade is insufficiently projected, or the saw blade is mounted obliquely. Furthermore, if the distance between the cuts, that is, the length of the connecting portion is shortened as described above in order to realize an opening piece that can be opened from either direction with excellent opening properties, the strength of the connecting portion is weak. Therefore, when the end 8 'of the unsealed piece collides with the stopper, the tear may occur at the joint portion.

紙製や樹脂製の鋸刃を装着させる場合は、生産ラインにおいて図1の状態に打ち抜いたカートンブランク紙を長手方向に移動させる方法が主流であるため、鋸刃装着工程のストッパーに開封片の端8’が衝突し、開封片8が折れ曲がる問題はないが、カートンブランク紙の移し変えや目視チェック等のハンドリング時に開封片8の折れ曲がりが発生する可能性がある。   When attaching a saw blade made of paper or resin, the main method is to move the carton blank paper punched in the state shown in FIG. 1 in the production line in the longitudinal direction. There is no problem that the edge 8 'collides and the opening piece 8 is bent, but the opening piece 8 may be bent during handling such as transfer of the carton blank paper or visual check.

これに対し、一方向からのみ開封が可能な従来から採用されている切れ目(図4)の場合、カートンブランクの長手方向に対して水平な切れ目の片方端に蓋板方向に傾斜した切れ目が設けてあり、他方端に長手方向に垂直な切れ目が設けてあるので、鋸刃装着工程のストッパーに開封片の端8’が衝突した際、開封片の端8’が衝撃を受ける方向、すなわち長手方向に水平な方向に対し、上記水平な切れ目の端部に設けられた各切れ目の方向が平行でないため、特許文献1で開示されている切れ目の形状に比較して開封片8が折れ曲がり難い。この切れ目の形状であれば鋸刃装着時における開封片8の折れ曲がりが回避可能であり、カートンブランク紙のハンドリングにも優れているが、前述したように、開封片8の開封方向は一方向からのみに限定される。
特開2003−291960号公報
On the other hand, in the case of the conventionally adopted cut that can be opened only from one direction (FIG. 4), a cut that is inclined in the direction of the cover plate is provided at one end of the cut parallel to the longitudinal direction of the carton blank. Since the other end is provided with a cut perpendicular to the longitudinal direction, when the end 8 ′ of the opening piece collides with the stopper in the saw blade mounting process, the end 8 ′ of the opening piece receives an impact, that is, the longitudinal direction. Since the direction of each cut provided at the end of the horizontal cut is not parallel to the horizontal direction, the opening piece 8 is less likely to be bent compared to the cut shape disclosed in Patent Document 1. With this shape of cut, it is possible to avoid bending of the opening piece 8 when the saw blade is mounted, and the handling of the carton blank paper is excellent, but as described above, the opening direction of the opening piece 8 is from one direction. Limited to only.

本発明について、好ましい実施態様を中心に説明する。
図2は、本発明のラップフィルム収納箱の開封片の切れ目形状を示している。切れ目形状は、基本的に主切れ目13と補助切れ目14から成る左右対称形状を有しており、この左右対称形状の間に傾斜した補助切れ目15を設ける。従って、掩蓋片6と開封片8を繋ぐつなぎ部16は傾斜した補助切れ目15が1箇所につきの両端に2箇所設けられることになる。
The present invention will be described focusing on preferred embodiments.
FIG. 2 shows the cut shape of the opening piece of the wrap film storage box of the present invention. The cut shape basically has a left-right symmetrical shape composed of a main cut 13 and an auxiliary cut 14, and an inclined auxiliary cut 15 is provided between the left-right symmetrical shapes. Therefore, the connecting portion 16 that connects the lid cover piece 6 and the opening piece 8 is provided with two inclined auxiliary cuts 15 at both ends of one place.

本発明のラップフィルム収納箱に採用する切取り線7は上記した3種の切れ目から構成されるが、その役割は次の通りである。すなわち、主切れ目13は掩蓋片6と開封片8との分離を容易にさせるため、長手方向に長い切れ目を有している。主切れ目13の両端に接して設けられた主切れ目の端部とは傾斜の向きが逆である補助切れ目14と傾斜した補助切れ目15は開封の自由度とつなぎ部16の強度を付与するために配置させている。つまり、図3に示した切取り線の場合、開封時のつなぎ部の破れは基本的に収納箱の長手方向と平行な方向しか許容されず(図面の下方向は若干許容される)、各切れ目の端部を結ぶ仮想線Tも収納箱の長手方向と平行なので、つなぎ部の長さの取り方にもよるが、開封片部分(特に先端部)に衝撃を受けるとつなぎ部の部分を起点に折れ曲がりが発生する可能性がある。一方、図4に示した切り取り線の場合、開封の方向は図を正面に見て右側から左側の方向に限定されるが、つなぎ部の破れは、傾斜した切れ目の先端部から縦方向への切れ目のどこかに達すればよいので、開封開始側が限定される問題はあるが、開封の自由度は大きい。加えて、各切れ目の先端部を結ぶ仮想線Uを複数作成できるが、何れの場合でもつなぎ部を通る仮想線が収納箱の長手方向と平行にはならないので、開封片部分に衝撃を受けてもつなぎ部の部分を起点にした折れ曲がりが発生し難い。   The tear line 7 employed in the wrap film storage box of the present invention is composed of the three types of cuts described above, and the role thereof is as follows. That is, the main cut 13 has a long cut in the longitudinal direction so that the lid cover piece 6 and the opening piece 8 can be easily separated. The auxiliary cut 14 and the inclined auxiliary cut 15 that are inclined in opposite directions to the ends of the main cut provided in contact with both ends of the main cut 13 are provided for providing the degree of freedom of opening and the strength of the connecting portion 16. It is arranged. That is, in the case of the cut line shown in FIG. 3, tearing of the joint portion at the time of opening is basically allowed only in the direction parallel to the longitudinal direction of the storage box (the downward direction in the drawing is allowed slightly), Since the imaginary line T that connects the ends of the box is also parallel to the longitudinal direction of the storage box, it depends on how the length of the connecting part is taken, but when the impact is applied to the opening piece (especially the tip), the connecting part starts. There is a possibility that bending will occur. On the other hand, in the case of the cut line shown in FIG. 4, the direction of opening is limited to the direction from the right side to the left side when the figure is viewed from the front, but the break of the joint is from the tip of the inclined cut to the vertical direction. Since it suffices to reach somewhere in the cut, there is a problem that the opening side is limited, but the degree of freedom of opening is large. In addition, it is possible to create a plurality of imaginary lines U connecting the leading ends of each cut, but in any case the imaginary line passing through the connecting portion is not parallel to the longitudinal direction of the storage box. It is difficult for bending to start from the connecting part.

従って、本発明のラップフィルム収納箱においては、補助切れ目14は開封の自由度(開封時の上下方向の自由度)を高めつつ、左右どちらの方向からでも開封可能とするために主切れ目13の両端にその端部とは傾斜の向きが逆になるように配置している。また、傾斜した補助切れ目15と隣合う補助切れ目14の間に存在する2つのつなぎ部16の仮想線は、互に傾斜が逆向きとなるので、開封片部分に衝撃を受けてもつなぎ部の部分を起点にした折れ曲がりが発生し難くなっている。   Therefore, in the wrap film storage box of the present invention, the auxiliary cut 14 increases the degree of freedom of opening (the degree of freedom in the vertical direction at the time of opening), and the main cut 13 can be opened from either the left or right direction. It arrange | positions so that the direction of an inclination may be reverse to the edge part at both ends. In addition, since the imaginary lines of the two connecting portions 16 existing between the inclined auxiliary cut 15 and the adjacent auxiliary cut 14 are opposite to each other, the opening piece portion receives an impact on the connecting piece portion. Bending starting from the part is less likely to occur.

本発明のラップフィルム収納箱の開封片8は上記各切れ目からなる切り取り線7に沿って引き剥がされるが、傾斜した補助切れ目15の両側に形成されるつなぎ部の数が少ないと、鋸刃装着工程において開封片の端8’がストッパーに衝突した際、開封片が上記つなぎ部の配置位置に沿って折れ曲がる可能性が高まる。一方で、配置するつなぎ部の数が多いと、開封時にちぎらなければならない箇所が多くなり、開封のスムーズさが損なわれる。これらを考慮し、長手方向の長さが約300mmのラップフィルム収納箱に対しては、つなぎ部を16〜24箇所(すなわち、傾斜した補助切れ目15を8〜12箇所)設けることが望ましい。さらに、つなぎ部16の長さに関しては、この長さが短すぎると、つなぎ部16の強度が著しく低下するため、鋸刃装着肯定のストッパーに衝突した際に開封片がつなぎ部の配置位置に沿って折れ曲がりやすい上、僅かな衝撃でちぎれてしまうことが懸念される。一方でこの長さが長いほどつなぎ部がちぎれにくい、すなわち開封片を剥しにくくなる。従って、つなぎ部16の長さは1.0〜1.5mmが望ましく、1.1〜1.3mmとすることがさらに望ましい。また、つなぎ部16の長さは全てのつなぎ目において統一した長さとする必要はなく、つなぎ部を配置させる位置によって長さが異なっていてもかまわない。   The opening piece 8 of the wrap film storage box of the present invention is peeled off along the cut line 7 formed by each of the above cuts, but if the number of connecting portions formed on both sides of the inclined auxiliary cut 15 is small, a saw blade is attached. When the end 8 'of the opening piece collides with the stopper in the process, the possibility that the opening piece bends along the arrangement position of the connecting portion is increased. On the other hand, if the number of connecting portions to be arranged is large, there are many places that must be torn at the time of opening, and the smoothness of opening is impaired. In consideration of these, it is desirable to provide 16 to 24 connecting portions (that is, 8 to 12 inclined auxiliary cuts 15) for a wrap film storage box having a longitudinal length of about 300 mm. Further, regarding the length of the connecting portion 16, if the length is too short, the strength of the connecting portion 16 is significantly reduced. It is easy to bend along, and there is a concern that it may be broken by a slight impact. On the other hand, the longer this length, the harder the tearing portion is torn, that is, the more difficult it is to peel off the opening piece. Therefore, the length of the connecting portion 16 is preferably 1.0 to 1.5 mm, and more preferably 1.1 to 1.3 mm. Further, the length of the connecting portion 16 does not have to be a uniform length in all the connecting portions, and the length may be different depending on the position where the connecting portion is arranged.

本発明のラップフィルム収納箱に採用する主切れ目13の両端部および補助切れ目14のそれぞれの傾斜角度に関しては、開封片を剥す際の操作のスムーズさを考慮し、主切れ目13両端部の傾斜角度θ1は10〜60°、補助切れ目14の傾斜角度θ2は30〜70°とするのが望ましい。尚、主切れ目13の全長については、収納箱の長さや必要とするつなぎ目の個数、内容物の重量等を考慮して適宜選択すればよいが、概ね10〜35mmの範囲から選択することが望ましい。補助切れ目14の全長についても収納箱や開封片の幅等を考慮して適宜選択すればよいが、概ね3〜5mmの範囲から選択することが望ましい。   Regarding the inclination angles of the both ends of the main cut 13 and the auxiliary cut 14 employed in the wrap film storage box of the present invention, the inclination angles of the both ends of the main cut 13 are taken into consideration in consideration of the smooth operation when peeling the unsealed piece. It is desirable that θ1 is 10 to 60 ° and the inclination angle θ2 of the auxiliary cut 14 is 30 to 70 °. The total length of the main cut 13 may be appropriately selected in consideration of the length of the storage box, the number of joints required, the weight of the contents, etc., but is preferably selected from a range of approximately 10 to 35 mm. . The total length of the auxiliary cut 14 may be selected as appropriate in consideration of the width of the storage box or the opening piece, but is preferably selected from a range of approximately 3 to 5 mm.

本発明のラップフィルム収納箱に採用する傾斜した補助切れ目15は鋸刃装着工程やハンドリング時の開封片の折れ曲がりを防止するために、ラップフィルム収納箱の長手方向に対して傾斜させる必要がある。その傾斜角度が小さいと傾斜した補助切れ目15が水平である場合との差異が殆どなくなり、ストッパーに衝突した際の耐衝撃性が失われる。反対に傾斜角度を大きくすると、補助切れ目14から傾斜した補助切れ目15への開封操作の不連続性が高まる上に、補助切れ目14の端部と傾斜した補助切れ目15の端部を直線的に結ぶ距離が長くなり、つなぎ部16がちぎれにくくなる、すなわち開封片をスムーズに剥せない。従って、傾斜した補助切れ目15の傾斜角度θ3は5〜30°とすることが望ましい。また、その傾斜の向きは、開封片のスムーズな開封性を実現させるため、開封片8を正面から見て、向かって左端の傾斜した補助切れ目15から順に第1、第2、・・・、第n−1、第nと番号をつけた場合、傾斜した補助切れ目15の傾斜の向きが交互に逆になるよう配置させることが望ましい。   The inclined auxiliary cut 15 employed in the wrap film storage box of the present invention needs to be inclined with respect to the longitudinal direction of the wrap film storage box in order to prevent the opening piece from being bent during the saw blade mounting process and handling. If the inclination angle is small, there is almost no difference from the case where the inclined auxiliary cut 15 is horizontal, and the impact resistance when colliding with the stopper is lost. On the contrary, when the inclination angle is increased, the discontinuity of the opening operation from the auxiliary cut 14 to the inclined auxiliary cut 15 is increased, and the end of the auxiliary cut 14 and the end of the inclined auxiliary cut 15 are linearly connected. The distance becomes longer and the connecting portion 16 becomes difficult to tear, that is, the unsealed piece cannot be peeled off smoothly. Accordingly, the inclination angle θ3 of the inclined auxiliary cut 15 is preferably 5 to 30 °. In addition, the direction of the inclination is the first, second,... In order from the auxiliary cut 15 inclined to the left end when the opening piece 8 is viewed from the front in order to realize smooth opening of the opening piece. When the numbers are assigned to the (n-1) th and the nth, it is desirable to arrange the inclined auxiliary cuts 15 so that the inclination directions are alternately reversed.

さらに、開封の最終端側の傾斜した補助切れ目15が底板3方向に傾斜している場合は(例えば第1番方向から開封を開始し、第n番が右下がりの傾斜となる場合)、開封最終端側のつなぎ部から小さな帯状、又はひも状の紙片残りが発生して概観を悪化させる場合が稀に発生するので、第1、第2の傾斜した補助切れ目15においては左上がり、第3〜第n−2の傾斜した補助切れ目15においては傾斜の向きが交互になるように配置し、第n−1、第nの傾斜した補助切れ目15においては右上がりとすることが更に望ましい。さらに、傾斜した補助切れ目15の長さに関しては、上述したつなぎ部の個数を考慮し、2〜8mmが望ましい。また、傾斜した補助切れ目15の位置に関しては、傾斜した補助切れ目15を極端に蓋板5寄りに設けると、主切れ目13の位置と離れるため、開封片を剥す際に不連続性が高まりスムーズに開封片を剥せない可能性がある上、開封片を剥した後に現れる鋸刃の露出部分が大きくなり、外観が損なわれるという問題がある。   Further, when the auxiliary cut 15 inclined toward the final end side of the opening is inclined in the direction of the bottom plate 3 (for example, when opening is started from the first direction and the nth is inclined downward to the right), the opening is performed. Since there are rare cases where a small strip or string-like piece of paper remains from the connecting portion on the final end side and deteriorates the appearance, the first and second inclined auxiliary cuts 15 rise to the left, and the third It is more preferable that the directions of inclination are alternately arranged in the (n-2) -thinned auxiliary cuts 15 and the n-1st and n-th inclined auxiliary cuts 15 are raised to the right. Further, the length of the inclined auxiliary cut 15 is preferably 2 to 8 mm in consideration of the number of the connecting portions described above. In addition, regarding the position of the inclined auxiliary cut 15, if the inclined auxiliary cut 15 is provided extremely close to the cover plate 5, it is separated from the position of the main cut 13, so discontinuity increases when the unsealed piece is peeled off and smoothly There is a possibility that the unsealed piece cannot be peeled off, and the exposed portion of the saw blade that appears after the unsealed piece is peeled off becomes large, and there is a problem that the appearance is impaired.

一方、傾斜した補助切れ目15を主切れ目13の水平部分よりも下方(開封片の端8’寄り)に設けると、開封片を剥した後にその部分の鋸刃が露出せず、ラップフィルムのカット性を阻害するという問題がある。従って、傾斜した補助切れ目15の位置は、補助切れ目14の蓋板5側端を結ぶ仮想線Pと、主切れ目13の水平部分を延長した仮想線Qで定められる範囲内に設けることが望ましい。   On the other hand, if the inclined auxiliary cut 15 is provided below the horizontal portion of the main cut 13 (closer to the end 8 ′ of the opening piece), the saw blade of the portion is not exposed after the opening piece is peeled off, and the wrap film is cut. There is a problem of inhibiting sex. Therefore, the position of the inclined auxiliary cut 15 is preferably provided within a range defined by a virtual line P connecting the end of the auxiliary cut 14 on the cover plate 5 side and a virtual line Q extending the horizontal portion of the main cut 13.

本発明のラップフィルム収納箱において、使用開始前まで開封片8は前記収納箱の前板1に糊材等で接着されているが、この接着方法は開封片と重なる前板部分に糊材と強く接着させるための円形状や楕円形状等のニス非塗布部分Sを複数箇所設け、開封後に開封片の裏面側表層が前板上のニス非塗布部分周辺に残る方法(点付け法)、左記ニス非塗布部分周囲に剥離用の半切れを付与し、開封後に半切れ付与部が剥離する方法(玉抜け法)、又はニス非塗布部と重なる開封片にニス非塗布部と相似拡大形状のミシン目等で囲まれた刳り貫き部10を付与し、開封後にそのミシン目等で囲まれた部分がそのまま前板上に残る方法(刳り抜き法)など、公知の方法を採用すれば良いが、どちらの方向からも開封可能とするため、左右対称形状を採用することが望ましい。   In the wrap film storage box of the present invention, the opening piece 8 is bonded to the front plate 1 of the storage box with a paste material or the like until the start of use, but this bonding method uses a paste material on the front plate portion overlapping the opening piece. A method in which a plurality of varnish non-applied portions S having a circular shape or an elliptical shape for strong adhesion are provided, and the back surface side layer of the unsealed piece remains around the varnish non-applied portion on the front plate after opening (spot method) A method of applying a half-cut for peeling around the varnish non-applied part and peeling off the half-cut application part after opening (ball drop method), or an open piece overlapping with the varnish non-applied part, A well-known method may be employed, such as a method in which a perforated portion 10 surrounded by perforations or the like is provided, and a portion surrounded by the perforations or the like remains on the front plate (opening method) after opening. In order to be able to open from either direction, a symmetrical shape is used. It is desirable to use.

[Evaluation methods]
In the process of attaching a metal saw blade to the carton blank shown in each of the examples and comparative examples, when the end 8 'of the opening piece collides with the stopper in the process, the opening piece 8 is bent or joined to be broken. When the frequency is less than 5 out of 1000 sheets, the evaluation is “◯”, and when 5 or more occur, the evaluation is “x”.
Next, the carton blank shown in each example and comparative example is assembled into a rectangular parallelepiped storage box, opened 50 times each from the left and right directions, in an operation that keeps the opening piece substantially perpendicular to the front plate, The case where no tearing occurred in the middle of the opening piece or the delamination of the lid piece was evaluated as “◯”, and the case where the left-handed occurrence occurred even once was evaluated as “x”. The results are shown in Table 1.

Figure 2008174284

実施例1〜3のラップフィルム収納箱では、鋸刃装着時の折れ曲がりや開封片の途中ちぎれが全く発生せず、生産性や使い勝手性に全く影響のないものであった。これに対し、比較例1では傾斜した補助切れ目15が傾斜していないので、鋸刃装着時に開封片の折れ曲がりが発生し易く、つなぎ部の長さが短い比較例2では鋸刃装着時につなぎ部のちぎれも多く発生した。比較例3ではつなぎ部の長さを長くしたので、鋸刃装着時のトラブルは解消できたが、開封片と掩蓋片の繋ぎが強固であるため、開封時に開封片のちぎれが発生した。比較例4の設計では傾斜した補助切れ目15が存在するので、鋸刃装着時のトラブルは発生しなかったが、補助切れ目14が存在せず、開封方向の自由度が小さくなったので、開封片の途中ちぎれが発生した。比較例5の設計では、つなぎ部の強度は弱く、開封方向の自由度も小さいので、鋸刃装着時の折れ曲がりや開封片の途中ちぎれの両方が発生した。   In the wrap film storage boxes of Examples 1 to 3, bending at the time of mounting the saw blade and tearing of the opened piece were not generated at all, and the productivity and usability were not affected at all. In contrast, in Comparative Example 1, since the inclined auxiliary cut 15 is not inclined, the opening piece is likely to bend when the saw blade is mounted, and in Comparative Example 2 where the length of the connecting portion is short, the connecting portion is attached when the saw blade is mounted. Many tears occurred. In Comparative Example 3, since the length of the connecting portion was increased, the trouble when the saw blade was mounted could be solved. However, since the opening piece and the lid cover piece were firmly connected, the opening piece was broken at the time of opening. In the design of Comparative Example 4, there is an inclined auxiliary cut 15 so that no trouble occurs when the saw blade is mounted. However, the auxiliary cut 14 does not exist and the degree of freedom in the opening direction is reduced. A tear occurred on the way. In the design of Comparative Example 5, since the strength of the joint portion was weak and the degree of freedom in the opening direction was small, both the bending when the saw blade was mounted and the tearing of the opening piece occurred.

尚、評価結果には表していないが、実施例2のように開封片8を正面に見て左端の傾斜した補助切れ目15が右上がりで、右端が左上がりの場合、開封終了側の端部つなぎ目に帯状又はひも状の紙片が残る場合がある。この紙片はラップのカット等の使い勝手性に何ら影響を及ぼさないが、見た目の問題もあるので、傾斜した補助切れ目15の傾斜は実施例1や3のように、左端側では左上がり1個又は2個、右端側では右上がりが1個又は2個設置することがさらに望ましい。     Although not shown in the evaluation results, as shown in Example 2, when the opening piece 8 is viewed from the front and the auxiliary cut 15 inclined at the left end rises to the right and the right end rises to the left, the end on the opening end side In some cases, strips or strings of paper strips remain at the joints. Although this piece of paper does not affect the usability of wrap cutting or the like, there is also a problem in appearance. Therefore, the inclined auxiliary cut 15 is inclined at the left end as shown in the first and third examples. It is more desirable to install two or one or two ascending to the right end.
