Description

この発明は、食品を包装するためのプラスチックフィルム製の食品包装体に関する。 The present invention relates to a food package made of a plastic film for packaging food.

海苔が巻かれないお握りや、すでに海苔が巻かれた状態のお握りなどの調理米飯食品は、特許文献１～特許文献３などに示すようなシート状のプラスチックフィルムで包装されている。また、封筒状のピロー包装体によって包装される場合もある。 Cooked rice balls such as rice balls that are not wrapped with seaweed and rice balls that are already wrapped with seaweed are wrapped in a sheet-shaped plastic film as shown in Patent Documents 1 to 3. It may also be wrapped in an envelope-shaped pillow package.

特許文献１～特許文献３などに示すシート状のプラスチックフィルムの場合、シートを折り畳みながら包装するので、作業に手間がかかる。専用の包装装置を使用すれば短時間で包装できるが、調理米飯食品の提供者の中には小規模な企業体の多く、そのような専用設備の導入は大きな負担となる。また、新しく普及しつつある調味米飯でさまざまな具材を米飯で包み、さらに外に海苔を巻いて、全体を平たく仕上げたものがある。このような調味米飯では具材の異なる多種類の商品を少数ずつ作る場合が多く、自動化された設備を使用するよりも手作業で包装するのが適している。 In the case of the sheet-shaped plastic film shown in Patent Documents 1 to 3, etc., the sheet is wrapped while being folded, so that the work is troublesome. Although it can be packaged in a short time by using a dedicated packaging device, many small companies are small companies among the providers of cooked rice foods, and the introduction of such dedicated equipment is a heavy burden. In addition, there is a new and popular seasoned cooked rice that is made by wrapping various ingredients in cooked rice and then wrapping seaweed on the outside to make the whole flat. In such seasoned cooked rice, many kinds of products with different ingredients are often made in small numbers, and it is more suitable to wrap them by hand rather than using automated equipment.

しかし、上述の通り、シート状のプラスチックフィルムによる包装を手作業で行うには手間がかかる。また、封筒状のピロー包装体でも口部を開いて食品を中に投入するのは面倒な作業である。 However, as described above, it is troublesome to manually wrap the sheet-shaped plastic film. Also, even with an envelope-shaped pillow package, it is a troublesome task to open the mouth and put food inside.

この発明は、中へ食品を投入するのが容易であり、包装に手間がかからず、開封時には簡単に開封できる食品包装袋を提供することを目的とする。 It is an object of the present invention to provide a food packaging bag in which it is easy to put food into it, it does not take time to package it, and it can be easily opened at the time of opening.

上記の課題を解決するために、この発明の食品包装袋は、略正方形状の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おり、第１辺およびこれに隣接する第２辺において辺に沿って第１シートと第２シートが接続されている辺部接続部と、第１辺と第２辺が交わる第１角部において頂部よりも内側で第１シートと第２シートが接続されている角部接続部と、第１角部の頂部において第１シートと第２シートが接続されていない非接続部と、第３辺およびこれに隣接する第４辺において第１シートと第２シートが接続されていない開口部とが設けられている。さらに、角部接続部は辺部接続部の端部につながりシートの外に向いて凸な凸部と、凸部の端部から頂部へ向かって形成されたシートの内に向いて凸な凹部とを有し、第１辺または第２辺のいずれかには第１シートまたは第２シートのいずれかが辺部の外に突き出た単層部を有することが好ましい。。 In order to solve the above problems, the food packaging bag of the present invention has two substantially square plastic sheets, the first sheet and the second sheet, which are overlapped with each other, and the first side and the adjacent first sheet thereof are overlapped with each other. The first sheet and the second sheet are inside the top at the side connection portion where the first sheet and the second sheet are connected along the two sides and the first corner portion where the first side and the second side intersect. The corner connection part to which the sheets are connected, the non-connection part to which the first sheet and the second sheet are not connected at the top of the first corner part, and the first on the third side and the fourth side adjacent thereto. An opening is provided in which the sheet and the second sheet are not connected. Further, the corner connection portion is connected to the end portion of the side connection portion and has a convex portion that is convex outward of the sheet and a concave portion that is convex toward the inside of the sheet formed from the end portion of the convex portion toward the top portion. It is preferable that either the first side or the second side has a single-layer portion in which either the first sheet or the second sheet protrudes from the side portion. ..

この発明の食品包装袋は、正方形の４辺のうち２辺が開口したラップ状であるために、内部への食品の投入が容易である。包装した時に、頂点部には第１シートおよび第２シートが接続されていない非接続部が形成されているので、ここから第１シートと第２シートを引きはがして簡単に大きく開封することができる。 Since the food packaging bag of the present invention has a wrap shape in which two of the four sides of the square are open, it is easy to put food into the inside. At the time of packaging, a non-connecting part to which the first sheet and the second sheet are not connected is formed at the apex, so that the first sheet and the second sheet can be peeled off from here and opened easily and greatly. can.

The left side view, FIG. 8 is the AA end view, and FIG. 9 is the BB end view.

食品包装袋１では第１シート２および第２シート３を重ね合わせている。第１シート２と第２シート３は食品包装用の薄いプラスチックシートであり、熱溶着により易剥離性の接着が行えるイージーピールフィルムよりなる。ほぼ同形の正方形であるが、本例においては正面図における手前側の第１シート２の右側が第２シート３よりも３～５ｍｍ程度広がっている。 In the food packaging bag 1, the first sheet 2 and the second sheet 3 are superposed. The first sheet 2 and the second sheet 3 are thin plastic sheets for food packaging, and are made of an easy peel film that can be easily peeled off by heat welding. Although it is a square having almost the same shape, in this example, the right side of the first sheet 2 on the front side in the front view is wider than the second sheet 3 by about 3 to 5 mm.

正方形の角部の一つを第１角部４とすると、その第１角部４で接する２つの辺をそれぞれ第１辺５、第２辺６とする。この第１辺５と第２辺６には第１シート２と第２シート３が接着された接続部が設けられている。一方、それ以外の２辺である第３辺７と第４辺８では第１シート２と第２シート３は接続されておらず、開口している。この構造はハンバーガー等の調理パンを包装するバーガーラップと呼ばれる紙製の包装材と共通する。 Assuming that one of the corners of the square is the first corner 4, the two sides in contact with the first corner 4 are the first side 5 and the second side 6, respectively. The first side 5 and the second side 6 are provided with a connecting portion to which the first sheet 2 and the second sheet 3 are adhered. On the other hand, in the other two sides, the third side 7 and the fourth side 8, the first sheet 2 and the second sheet 3 are not connected and are open. This structure is common to a paper packaging material called burger wrap that wraps cooking bread such as hamburgers.

第１シート２と第２シート３の接続についてさらに説明する。第１辺５および第２辺６において第１角部４の反対側の端部から辺に沿って帯状に辺部接続部９が形成されている。この辺部接続部９は第１角部４の手前で終わっている。そして、辺部接続部９の終点部に続いて角部接続部１０が設けられている。この角部接続部１０は第１角部４の頂部よりも内側に形成されている。そして、第１角部の頂部において角部接続部１０の外側には第１シート２と第２シート３が接続されていない非接続部１１が設けられている。 The connection between the first sheet 2 and the second sheet 3 will be further described. On the first side 5 and the second side 6, the side connecting portion 9 is formed in a band shape along the side from the opposite end of the first corner portion 4. This side connection portion 9 ends in front of the first corner portion 4. A corner connection portion 10 is provided following the end point portion of the side connection portion 9. The corner connecting portion 10 is formed inside the top of the first corner portion 4. A non-connecting portion 11 to which the first sheet 2 and the second sheet 3 are not connected is provided outside the corner connecting portion 10 at the top of the first corner portion.

辺部接続部９および角部接続部１０は易剥離性接着となっている。イージーピールシールとも呼ばれる接続であり、ある程度以上の力が加わらない時には剥離しないが、開封しようとして引き剥がそうとする力が加われば簡単に隔離するような接着状態である。イージーピールフィルムと呼ばれるプラスチックシート同士を重ねて熱圧着すれば、このような接続をすることができる。また、イージーピール性の接着剤によってもそのような接続をすることができる。 The side connection portion 9 and the corner connection portion 10 are easily peelable and bonded. It is a connection also called an easy peel seal, and it does not peel off when a certain amount of force is not applied, but it is in an adhesive state where it can be easily separated when a force to peel it off when trying to open it is applied. Such a connection can be made by stacking plastic sheets called easy peel films and thermocompression bonding them. Such a connection can also be made with an easy-peel adhesive.

本例では角部接続部１０はさらに２つの部分に分けられる。第１辺５および第２辺６の辺部接続部９の端部につながっている部分は、シートの外に向いて凸な曲線になっている凸部１０ａである。そして、凸部１０ａに続いて頂部へ向かった曲線である凹部１０ｂが形成されている。この凹部１０ｂはシートの内に向いて凸な曲線である。この構成により、頂部に最も近いところでは凹部１０ｂの端部同士が頂部に向いて突き出した形状になっている。頂部の非接続部１１より第１シート２と第２シート３を引き剥がそうとすると、この角部接続部１０の形状により角部接続部１０は確実に剥離し、剥離は第１辺５および第２辺６の辺部接続部９に進行していく。 In this example, the corner connection portion 10 is further divided into two portions. The portion of the first side 5 and the second side 6 connected to the end of the side connection portion 9 is a convex portion 10a having a convex curve toward the outside of the sheet. Then, a concave portion 10b, which is a curved line toward the top, is formed following the convex portion 10a. The recess 10b is a curved line that is convex toward the inside of the sheet. With this configuration, the ends of the recesses 10b project toward the top at the position closest to the top. When the first sheet 2 and the second sheet 3 are to be peeled off from the non-connecting portion 11 on the top, the corner connecting portion 10 is surely peeled off due to the shape of the corner connecting portion 10, and the peeling is performed on the first side 5 and the first side. Proceed to the side connection portion 9 of the second side 6.

また、本例では第１辺または第２辺のいずれかには第１シートまたは第２シートのいずれかが辺部の外に突き出た単層部１２が形成される。図２では第２辺６の外側に３～５ｍｍ程度の幅で第１シートが突き出している。このように単層部を設けることにより、開封時に非接続部１１において第１シート２と第２シート３を開きやすくなる。 Further, in this example, a single layer portion 12 in which either the first sheet or the second sheet protrudes outside the side portion is formed on either the first side or the second side. In FIG. 2, the first sheet protrudes to the outside of the second side 6 with a width of about 3 to 5 mm. By providing the single layer portion in this way, it becomes easy to open the first sheet 2 and the second sheet 3 in the non-connecting portion 11 at the time of opening.

第１シート２および第２シート３はいずれも薄く透明なプラスチックフィルムである。辺部接続部９と角部接続部１０は接着の仕方によって若干半透明になる場合もあるが、おおむね透明と見てよい。したがって、食品包装袋１も印刷が施されていなければ全体的に透明である。 Both the first sheet 2 and the second sheet 3 are thin and transparent plastic films. The side connection portion 9 and the corner connection portion 10 may be slightly translucent depending on the method of adhesion, but can be regarded as generally transparent. Therefore, the food packaging bag 1 is also transparent as a whole if it is not printed.

図２から図７に示す形態は、食品包装袋という物品においては新しいものであり、特に調理米飯食品用の包装袋としては斬新であり、意匠性が高い。 The form shown in FIGS. 2 to 7 is new in an article called a food packaging bag, and is particularly novel as a packaging bag for cooked rice food, and has a high design.

図１０は食品包装袋を束ねた状態を示す斜視図である。食品包装袋１は大きな連続シートから切り出して製造することができるが、切り出すときに第３辺７または第４辺８の外側まで第１シート２および第２シート３の延長部１３を設け、第３辺７または第４辺８に沿ってミシン目などの切断補助線を設けることができる。そして、延長部１３が上側になるようにそろえて複数の食品包装袋１を重ね、延長部１３の上辺を接着剤などで接続することによって食品包装袋１の集合体を得ることができる。また、延長部１３には吊り下げ用穴１４を設けている。 FIG. 10 is a perspective view showing a state in which food packaging bags are bundled. The food packaging bag 1 can be manufactured by cutting out from a large continuous sheet, but when cutting out, the first sheet 2 and the extension portion 13 of the second sheet 3 are provided to the outside of the third side 7 or the fourth side 8, and the second sheet is provided. A cutting auxiliary line such as a perforation can be provided along the 3rd side 7 or the 4th side 8. Then, by aligning the extension portions 13 so as to be on the upper side, stacking the plurality of food packaging bags 1 and connecting the upper sides of the extension portions 13 with an adhesive or the like, an aggregate of the food packaging bags 1 can be obtained. Further, the extension portion 13 is provided with a hanging hole 14.

フックなどを吊り下げ用穴１４に通すことによって、食品包装袋の集合体を吊り下げることができる。使用時には、手前側の食品包装袋をつかみ、切断補助線に沿って切り外せば、図２などに示す食品包装袋１を一つ取り出すことができる。 By passing a hook or the like through the hanging hole 14, the aggregate of food packaging bags can be hung. At the time of use, if the food packaging bag on the front side is grasped and cut off along the cutting auxiliary line, one food packaging bag 1 shown in FIG. 2 or the like can be taken out.

ついで、この食品包装袋を使用方法および食品包装袋を用いた包装食品について説明する。第３辺７および第４辺８は第１シート２と第２シート３が接続されていない開口部になっているので、ここを開いて包装対象の食品ｘを中に入れる。食品としては、調理パンや菓子でもよいが調理米飯が特に適している。図１０の例では、「おにぎらず」とよばれる海苔に包まれた具材入りの米飯を包装している。三角おにぎりよりも幅が広く、正面から見て略長方形の形状になっている。下側の２辺が開口するため、簡単に開くことができ、さらに食品の投入も容易である。開口が広いのでべたつきやすい米飯食品でも問題なく投入できる。 Next, a method of using this food packaging bag and a packaged food using the food packaging bag will be described. Since the third side 7 and the fourth side 8 are openings to which the first sheet 2 and the second sheet 3 are not connected, they are opened and the food x to be packaged is put inside. As the food, cooked bread and confectionery may be used, but cooked rice is particularly suitable. In the example of FIG. 10, cooked rice containing ingredients wrapped in seaweed called "Onigiri" is wrapped. It is wider than a triangular rice ball and has a substantially rectangular shape when viewed from the front. Since the lower two sides are open, it can be easily opened and food can be easily added. Since the opening is wide, even cooked rice foods that are easily sticky can be put in without problems.

そして、開口部を閉じるようにしながら左右及び下側の余ったシート部分を折り畳んでいき、折り畳み端を粘着テープやシールで固定することにより、図１１に示す包装食品が得られる。店舗の棚に陳列するときも、図１１に示すように第１角部４を上に向けておけば、中の食品がよく見えるようになる。 Then, the left and right and lower surplus sheet portions are folded while closing the opening, and the folded ends are fixed with an adhesive tape or a seal to obtain the packaged food shown in FIG. 11. Even when displaying on the shelves of a store, if the first corner 4 is turned up as shown in FIG. 11, the food inside can be clearly seen.

さらに、包装食品の開封について説明する。頂部の非接続部１１は第１シート２と第２シート３が接続されていないので、それぞれのシートの角を指でつまむことができる。そして、第１シート２と第２シート３を相互に引き剥がすことにより、食品包装袋１の上部を開封する。頂部から始まる剥離は、角部接続部１０の凹部１０ｂにより左右に分かれて進行し、それぞれの剥離は凹部１０ａおよび辺部接続部に沿って進行して、大きな開口を形成する。易剥離性の接着であるため、簡単に開封することができ、シートの途中が破れるような不規則な開封もおこらない。 Further, the opening of the packaged food will be described. Since the first sheet 2 and the second sheet 3 are not connected to the non-connecting portion 11 at the top, the corners of the respective sheets can be pinched with fingers. Then, the upper part of the food packaging bag 1 is opened by peeling the first sheet 2 and the second sheet 3 from each other. The peeling starting from the top progresses separately to the left and right by the recess 10b of the corner connecting portion 10, and each peeling proceeds along the recess 10a and the side connecting portion to form a large opening. Since it is an easily peelable adhesive, it can be easily opened, and irregular opening such as tearing in the middle of the sheet does not occur.

上部に形成された大きな開封口から中の食品を取り出してもよい。あるいは、下部のまだ開封されていない部分をつかみ、上部に表れた食品を食べてもよい。従来のラップで包装されたハンバーガー等の場合、食品を投入した開口部を再び開いて、この側から食品を食べるが、本発明の包装食品の場合は、その反対で上部側から食べることになる。開封した状態も従来のバーガーラップとは全く異なる外観となる。折り畳み端を固定しているシールをはがしたり折り畳み部を開いたりする必要はない。 The food inside may be taken out from the large opening formed at the top. Alternatively, you may grab the unopened portion of the lower part and eat the food that appears in the upper part. In the case of a hamburger or the like wrapped in a conventional wrap, the opening in which the food is put is opened again and the food is eaten from this side, but in the case of the packaged food of the present invention, the opposite is true and the food is eaten from the upper side. .. The opened state also has a completely different appearance from the conventional burger wrap. There is no need to remove the seal that secures the folded end or open the folded part.
