特許文献１や特許文献２に記載のサンドイッチ用包装材は、等脚台形の食品収容部を有し、ここに直角三角形のサンドイッチを入れて包装する。すると、サンドイッチの斜辺に沿った面が包装体の正面に表れる。その正面にはカットテープが設けられているので、このカットテープを引き上げることによって開封し、その開口部より、中のサンドイッチを取り出すことができる。 The sandwich packaging material described in Patent Literature 1 and Patent Literature 2 has an isosceles trapezoidal food storage portion, and a right triangle sandwich is placed and packaged therein. Then, the surface along the oblique side of the sandwich appears on the front surface of the package. Since a cut tape is provided in front of the cut tape, the cut tape can be opened to open and the sandwich inside can be taken out from the opening.

しかし、カットテープにより開封できる幅は限られていて、厚みのあるサンドイッチを簡単に取り出すことはできない。そこで、多数のカットテープを平行に設けることが考えられるが、それらのカットテープを一度に引き上げることはできず、広い幅の開口を得るためには、何回も開封作業を行う必要がある。特許文献２のサンドイッチ用包装袋では、三角形サンドイッチの斜辺に沿った面全体を覆うだけの多数のヒートシールを設け、しかも、幅広く簡単に開封できるとされている。しかし、その構造は複雑であり、製造にかかる時間とコストが大きくならざるをえない。 However, the width that can be opened with a cut tape is limited, and a thick sandwich cannot be easily taken out. Therefore, it is conceivable to provide a large number of cut tapes in parallel. However, the cut tapes cannot be pulled up at one time, and it is necessary to perform an opening operation many times in order to obtain a wide opening. In the sandwich packaging bag of Patent Document 2, a large number of heat seals are provided so as to cover the entire surface along the hypotenuse of the triangular sandwich, and it can be opened widely and easily. However, the structure is complicated, and manufacturing time and cost must be large.

この発明は、大きく簡単に開封でき、サンドイッチを容易に取り出すことができる包装袋を提供することを目的とする。 An object of the present invention is to provide a packaging bag that can be opened easily and can be easily taken out.

上記の課題を解決するために、この発明のサンドイッチ包装用袋は、略等脚台形状の食品収容部を有する２枚のプラスチックシートである第１シートおよび第２シートを重ね合わせて形成した本体部と、第２シートに設けられた切り込み部と、切り込み部の上に設けられたプラスチックシートである第３シートを有し、食品収容部である等脚台形状の上辺を一辺とする長方形の内部において切り込み部は設けられていて、その切り込み部は上辺に平行な１本の切り込み線とこれに垂直な２本の切り込み線によって構成されている。さらに、第３シートは、切り込み部を覆うようにして第２シートに接続された覆い部と、覆い部に隣接し第２シートに接続していないつまみ部を有し、切り込み部の内側において第２シートと第３シートが接続されている内側接続部と、切り込み部に沿った第２シートと第３シートが接続されていない非接続部と、切り込み部の外側において第２シートと第３シートが接続されている外側接続部が形成されていることが好ましい。 In order to solve the above-mentioned problem, a sandwich packaging bag according to the present invention is a main body formed by overlapping a first sheet and a second sheet, which are two plastic sheets each having a food container having a substantially isosceles trapezoidal shape. A rectangular sheet with an upper side of an isosceles trapezoidal shape that is a food container, and a third sheet that is a plastic sheet provided on the cut part. A cut portion is provided inside, and the cut portion is constituted by one cut line parallel to the upper side and two cut lines perpendicular to the cut line. Further, the third sheet has a cover part connected to the second sheet so as to cover the cut part, and a knob part adjacent to the cover part and not connected to the second sheet. 2nd sheet and 3rd sheet | seat are connected inside, 2nd sheet | seat along the notch | incision part, 3rd sheet | seat is not connected, 2nd sheet | seat and 3rd sheet | seat outside the notch | incision part It is preferable that an outer connection portion to which is connected is formed.

この発明のサンドイッチ包装用袋は、第３シートを引き剥がすことにより切り込み部に沿った大きな開封口を得ることができ、中のサンドイッチを簡単に取り出すことができる。 The sandwich packaging bag of the present invention can obtain a large opening along the cut portion by peeling off the third sheet, so that the sandwich can be easily taken out.

The rear view is the same as the front view, and the left side view is symmetrical to the right side view.

サンドイッチ包装用袋１は、ほぼ外形が同じ第１シート２と第２シート３の重ね合わせにより形成され、さらに、第２シート３の上に第３シート４が取り付けられている。第１シート２、第２シート３および第３シート４はいずれも薄く透明がプラスチックフィルムであり、サンドイッチ包装用袋１も印刷が施されていなければ全体的に透明である。 The sandwich packaging bag 1 is formed by superimposing a first sheet 2 and a second sheet 3 having substantially the same outer shape, and a third sheet 4 is attached on the second sheet 3. The first sheet 2, the second sheet 3, and the third sheet 4 are all thin and transparent plastic films, and the sandwich packaging bag 1 is also transparent as a whole if it is not printed.

サンドイッチ包装用袋１は、上辺が下辺より短い等脚台形の形状をした食品収容部６を有する。この食品収容部６において、上辺７および側部の斜辺８では第１シート２と第２シート３が接続されている。一方、下辺９では第１シート２と第２シート３は接続されていない。したがって、食品収容部６は下辺９のみが開いた袋形状になっており、この中にサンドイッチを収容できるようになっている。したがって、食品収容部６の形状は収容されるサンドイッチの形状に対応している。このサンドイッチ包装用袋には、直角三角形のサンドイッチが収容されるが、上辺７はサンドイッチの厚さとほぼ同じか若干広めになっており、斜辺７の垂線に対する角度θはサンドイッチの頂点の角度の半分になっている。 The sandwich packaging bag 1 has a food container 6 having an isosceles trapezoidal shape whose upper side is shorter than the lower side. In the food container 6, the first sheet 2 and the second sheet 3 are connected at the upper side 7 and the oblique side 8 of the side part. On the other hand, at the lower side 9, the first sheet 2 and the second sheet 3 are not connected. Accordingly, the food container 6 has a bag shape in which only the lower side 9 is open, and can accommodate the sandwich therein. Therefore, the shape of the food container 6 corresponds to the shape of the sandwich to be stored. This sandwich packaging bag contains a right triangle sandwich, but the upper side 7 is approximately the same as or slightly wider than the thickness of the sandwich, and the angle θ of the hypotenuse 7 with respect to the perpendicular is half the apex angle of the sandwich. It has become.

食品収容部６の上部には耳部１０が設けられ、下部には折り畳み部１１が設けられている。この耳部１０と折り畳み部１１には特に制限はないが、ここでは長方形状とし、連続シートから効率よく切り出せるようにしている。 An ear part 10 is provided at the upper part of the food storage part 6, and a folding part 11 is provided at the lower part. Although there is no restriction | limiting in particular in this ear | edge part 10 and the folding part 11, It is made rectangular shape here so that it can cut out efficiently from a continuous sheet.

図１０は第１シートを示す正面図、図１１は第２シートを示す正面図、図１２は第３シートを示す正面図である。第１シートと第２シートはほぼ同じ形状であり、食品収容部を形成する等脚台形状の部分と、その上の耳部を形成する長方形状の部分と、下の折り畳み部を形成する長方形状の部分を有する。この第１シートと第２シートにより本体部が形成される。そして、第２シートには、切り込み部１２が形成されている。この切り込み部１２は、等脚台形状の中央部に設けられており、特に等脚台形状の上辺７を一辺とする長方形の内部に収まっている。さらに、この切り込み部１２は、上辺７に平行な１本の切り込み線１２ａと、これに垂直な２本の切り込み線１２ｂによって構成されていている。そして、上辺７に平行な切り込み線１２ａは上辺７に近い位置に設けられており、一方、下辺に近い部分には設けられていない。したがって、下側が開いたコの字状の切り込みになり、この中に囲まれた部分は下辺の近くにおいて第２シートとつながっている。この切り込み部１２は、なるべく大きく形成することが好ましく、中に収容されるサンドイッチを取り出すのに十分な広さにする。 10 is a front view showing the first sheet, FIG. 11 is a front view showing the second sheet, and FIG. 12 is a front view showing the third sheet. The first sheet and the second sheet have substantially the same shape, an isosceles trapezoidal part that forms the food container, a rectangular part that forms the upper ear part, and a rectangular that forms the lower folding part. It has a shaped part. A main body is formed by the first sheet and the second sheet. A cut portion 12 is formed in the second sheet. The cut portion 12 is provided at the center of the isosceles trapezoidal shape, and particularly fits inside a rectangle having the upper side 7 of the isosceles trapezoidal shape as one side. Further, the cut portion 12 is composed of one cut line 12a parallel to the upper side 7 and two cut lines 12b perpendicular to the cut line 12a. The cut line 12a parallel to the upper side 7 is provided at a position close to the upper side 7, and is not provided at a portion close to the lower side. Therefore, the lower side is an open U-shaped cut, and the portion surrounded by the cut is connected to the second sheet near the lower side. The notch 12 is preferably formed as large as possible and is wide enough to take out the sandwich accommodated therein.

第３シート４は、第２シート３の切り込み部１２を覆うための覆い部１３と、その上に設けられるつまみ部１４を有する。覆い部１３は概ね長方形であり、切り込み部１２よりも若干広め、すなわち、切り込み部１２の外側に接続部を形成できるだけの大きさを有する。そして、つまみ部１４は本例では台形になっている。 The 3rd sheet 4 has the cover part 13 for covering the notch part 12 of the 2nd sheet | seat 3, and the knob part 14 provided on it. The cover portion 13 is generally rectangular and is slightly wider than the cut portion 12, that is, has a size sufficient to form a connection portion outside the cut portion 12. And the knob part 14 is trapezoid in this example.

第２シート３と第３シート４は熱溶着等により接続されている。切り込み部１２の内側において第２シート３と第３シート４が接続されている内側接続部１５が設けられている。そして、その外側には、切り込み部１２に沿った第２シート３と第３シート４が接続されていない非接続部１６が設けられ、さらに、切り込み部１２の外側において第２シート３と第３シート４が接続されている外側接続部１７が形成されている。この外側接続部１７は切り込み部１２を囲むように長方形状に形成されており、これによって、切り込み部１２の周囲を閉鎖しており、切り込み部１２を通って空気が出入りできないようになっている。また、第３シート４の上部のつまみ部１４は第２シート３に接続されていない。 The second sheet 3 and the third sheet 4 are connected by heat welding or the like. An inner connection portion 15 to which the second sheet 3 and the third sheet 4 are connected is provided inside the cut portion 12. And the non-connecting part 16 to which the 2nd sheet | seat 3 and the 3rd sheet | seat 4 along the notch part 12 are not connected is provided in the outer side, and also the 2nd sheet | seat 3 and 3rd in the outer side of the notch part 12 are provided. An outer connection portion 17 to which the sheet 4 is connected is formed. The outer connection portion 17 is formed in a rectangular shape so as to surround the notch portion 12, thereby closing the periphery of the notch portion 12 so that air cannot enter and exit through the notch portion 12. . Further, the upper knob portion 14 of the third sheet 4 is not connected to the second sheet 3.

ついで、このサンドイッチ包装用袋の使用方法について説明する。サンドイッチ包装用袋の下部は開いているので、ここからサンドイッチｘを挿入する。サンドイッチｘの直角三角形の頂点側から挿入し、奥まで入れる。このとき、サンドイッチｘの斜辺に沿った面が第２シート３に当たるような向きで入れる。そして、サンドイッチ包装用袋の下部の余った部分をキャラメル折りのようにして折り畳み、粘着テープやシールなどで止めれば包装が完了する。図１３はサンドイッチ包装用袋の使用状態を示す斜視図である。 Next, a method of using this sandwich packaging bag will be described. Since the lower part of the sandwich packaging bag is open, the sandwich x is inserted from here. Insert from the apex side of the right triangle of sandwich x and insert it all the way. At this time, it is inserted in such a direction that the surface along the hypotenuse of the sandwich x hits the second sheet 3. Then, the remaining portion of the lower part of the sandwich packaging bag is folded like a caramel fold, and the packaging is completed by stopping with an adhesive tape or a seal. FIG. 13 is a perspective view showing the usage state of the sandwich packaging bag.

三角サンドイッチは、通常は正方形または長方形の２枚またはそれ以上のパンの間に具材を挟みこむことによって作られ、その後、対角線に沿って２つに切断される。こうして、直角三角形のサンドイッチができる。斜辺に沿った面が切断面であり、この面ではサンドイッチの具材がよく見えるようになっている。包装したときに、この切断面は第３シート４が設けられた位置に表れる。そして、第２シート３と第３シート４は透明であるので、この包装体を店頭に陳列したときに、外から具材がよく観察できる。 Triangular sandwiches are made by sandwiching ingredients between two or more breads, usually square or rectangular, and then cut into two along a diagonal. In this way, a right triangle sandwich is made. The surface along the hypotenuse is the cut surface, and on this surface the sandwich ingredients are clearly visible. When packaged, this cut surface appears at the position where the third sheet 4 is provided. And since the 2nd sheet | seat 3 and the 3rd sheet | seat 4 are transparent, when this packaging body is displayed in a shop front, ingredients can be observed well from the outside.

このサンドイッチ包装用袋は、つまみ部１４を指でつまんで第３シート４を第２シート２から引きはがすことによって簡単に行うことができる。第２シート３と第３シート４は熱溶着などによって接続されているだけなので、簡単に引きはがすことができる。そして、第２シート３の切り込み部１２の内側の部分は内側接続部１５により第３シート４に接続されているので、第３シート４とともにサンドイッチ包装用袋から引きはがされる。こうして、大きな開口が得られる。この開口部より中のサンドイッチを簡単に取り出すことができる。 This sandwich packaging bag can be easily obtained by pinching the knob portion 14 with a finger and peeling the third sheet 4 from the second sheet 2. Since the second sheet 3 and the third sheet 4 are merely connected by thermal welding or the like, they can be easily peeled off. And since the inner part of the notch part 12 of the 2nd sheet | seat 3 is connected to the 3rd sheet | seat 4 by the inner side connection part 15, it peels from the bag for sandwich packaging with the 3rd sheet | seat 4. FIG. A large opening is thus obtained. The sandwich in the opening can be easily taken out.
