Description

この発明は、にぎり飯に海苔等のシート状食品を開封時に巻いて食するようにしたおにぎりを包装するためのおにぎり用包装材に関するものである。 The present invention relates to a rice ball packaging material for wrapping rice balls in which sheet food such as seaweed is rolled and eaten on rice balls.

スーパーマーケットやコンビニエンスストア等で販売されているおにぎりの包装材としては、特許文献1に記載のものがある。この包装材で握り飯を包装したものは、外フィルムを引き裂いてその左右各部分が分離するように引っ張ると、内フィルムも左右各片に分離して、握り飯にシート状食品が巻かれた状態で開封されるようになっており、開封直前までシート状食品が握り飯に接触しないため、パリパリとした食感を楽しむことができる。しかも、包装時、収容される握り飯に比べて大きな四角形状となり、三角形の握り飯の形状に沿わせるようにしたものに比べて高級感がある。   As a rice ball packaging material sold in supermarkets, convenience stores, etc., there is one described in Patent Document 1. In this packaging material, the rice is wrapped so that when the outer film is torn and the left and right parts are separated, the inner film is also separated into the left and right pieces, and the sheet food is wrapped around the rice. Since it is opened and the sheet-like food does not come into contact with the hand-grip rice until just before opening, it is possible to enjoy a crispy texture. In addition, when packaged, it has a larger quadrilateral shape compared to the gripping rice to be accommodated, and there is a sense of quality compared to a shape that follows the shape of the triangular gripping rice.

しかし、握り飯を包装していない状態の四角形の箱状の包装材は、嵩張るため保管や輸送に適したものではなく、また、シート状食品が割れやすいものであった。   However, the rectangular box-shaped packaging material in a state where no nigiri is packaged is bulky and is not suitable for storage or transportation, and the sheet-like food is easily broken.

As shown in FIG. 1, a cut tape 6 is attached to the outer film portion 1 across the short sides of the outer film portion 1 facing each other at the center in the left-right direction, and is guided by the cut tape 6. It can be torn. In addition, you may comprise the outer film part 1 with the film which has tear directionality in a vertical direction (elongate direction) instead of providing the cut tape 6. FIG.

外フィルム部1の1組の互いに対向する辺(短辺)の各中央部には、カットテープ6の外側に、2つの切込みを設けることにより、開封操作片7が形成されている。この食品包装材は、前記のいずれかの短辺の側の開封操作片7を引っ張ることにより、その対向する短辺に至るまで外フィルム部1の左右方向中央部が帯状に引き裂かれ、外フィルム部1を分割できるようになっている。   An opening operation piece 7 is formed by providing two cuts on the outer side of the cut tape 6 at each central portion of a pair of opposing sides (short sides) of the outer film portion 1. In this food packaging material, by pulling the opening operation piece 7 on one of the short sides described above, the central portion in the left-right direction of the outer film portion 1 is torn into a strip shape until reaching the opposite short side, and the outer film Part 1 can be divided.

内フィルム部2は、外フィルム部1に対して剥離可能に接着させられる左片2aと右片2bの2枚のフィルムにより構成される。内フィルム部2の左片2aと右片2bは、それぞれ長辺が外フィルム部1の長辺と同じ長さで、短辺が外フィルム部1の短辺の半分より長くなっており、図2に示したように、中央でそれぞれの自由端部が重なるようにしている。   The inner film part 2 is composed of two films, a left piece 2a and a right piece 2b, which are detachably bonded to the outer film part 1. Each of the left piece 2a and the right piece 2b of the inner film part 2 has the same long side as the long side of the outer film part 1, and the short side is longer than half the short side of the outer film part 1, As shown in FIG. 2, the respective free ends overlap at the center.

外フィルム部1と内フィルム部2との間には、外周縁部の内側にシールされていない領域があり、この部分がシート状食品4を収容する収容部3となっている。シート状食品4は、海苔や、ゼラチンでシート状に形成された鰹節や昆布等であり、適宜選択使用される。シート状食品4の収容部3への収容作業は、手作業で行う方法、機械で自動的に挿入する方法のいずれで行ってもよい。   Between the outer film part 1 and the inner film part 2, there is an unsealed area inside the outer peripheral edge part, and this part serves as a housing part 3 for housing the sheet-like food 4. The sheet-like food 4 is laver, bonito or kelp formed in a sheet shape with gelatin, and is appropriately selected and used. The storing operation of the sheet-like food 4 in the storing unit 3 may be performed by either a manual method or a method of automatically inserting by a machine.

また、この実施形態において、各おにぎり用包装材Aは、左右の長尺方向のシール部5a,5bと5c,5dにより中央の収容部3と左右側部A4,A5となる領域とに区画されており、この左右側部A4,A5となる領域において、長尺方向の中央付近には、それぞれ2本の短尺方向の切れ目8a〜8dが形成されている。この切れ目8a〜8dは、後述の箱状に形成する際に付けられる、正面側部A1、底部A2、及び背面側部A3を形成するための平行な2本の短尺方向の折り目の延長線上に位置する。   Moreover, in this embodiment, each packaging material A for rice balls is divided into a region that becomes a central housing portion 3 and left and right side portions A4, A5 by left and right longitudinal seal portions 5a, 5b, 5c, 5d. In the regions to be the left and right side portions A4 and A5, two short cuts 8a to 8d are formed near the center in the long direction. The cuts 8a to 8d are formed on the extension lines of two parallel short folds for forming the front side part A1, the bottom part A2, and the back side part A3, which are attached when forming a box shape to be described later. To position.

左右の長尺方向の各2本のシール部5a,5bと5c,5dは、それぞれ平行に設けられており、シール部5a,5b間と5c,5d間の各シールされていない部分で、容易に折り曲げられるようにしている。   Each of the two seal portions 5a, 5b and 5c, 5d in the longitudinal direction on the left and right is provided in parallel to each other, and is easy between the seal portions 5a, 5b and the unsealed portions between 5c, 5d. It can be bent.

おにぎり用包装材Aは、以下のように図3に示した型材9を利用して箱状に形成される。型材9は、プラスチック、板紙、金属製のもの等とすることができる。まず、おにぎり用包装材Aを、長尺方向の一端が型材9の正面9aに接し、他端が型材9の背面9cに接するように型材9に沿わせる。おにぎり用包装材Aは、底部A2となる長尺方向の中央が型材9の底面9bの真下に位置するようにする。   The rice ball packaging material A is formed in a box shape using the mold material 9 shown in FIG. 3 as follows. The mold material 9 can be made of plastic, paperboard, metal or the like. First, the rice ball packaging material A is placed along the mold material 9 so that one end in the longitudinal direction is in contact with the front surface 9 a of the mold material 9 and the other end is in contact with the back surface 9 c of the mold material 9. The rice ball packaging material A is set so that the center in the longitudinal direction, which is the bottom portion A <b> 2, is located directly below the bottom surface 9 b of the mold material 9.

そして、型材9の底面9bと正面9aとのなす角、及び型材9の底面9bと背面9cとのなす角を利用して、おにぎり用包装材Aに短尺方向(横方向)の折り目を付けることにより、正面側部A1、底部A2、及び背面側部A3を形成する。   Then, using the angle formed between the bottom surface 9b of the mold material 9 and the front surface 9a and the angle formed between the bottom surface 9b and the back surface 9c of the mold material 9, the rice ball packaging material A is creased in the short direction (lateral direction). Thus, the front side portion A1, the bottom portion A2, and the back side portion A3 are formed.

さらに、型材9の正面9と左右各側面9d、9eとのなす角、型材9の底面9bと左右各側面9d、9eとのなす角、及び型材9の背面9cと左右各側面9d、9eとのなす角を利用して、おにぎり用包装材Aに長尺方向(縦方向)の折り目を付けることにより、左右側部A4,A5を形成する。   Furthermore, the angle formed by the front surface 9 of the mold material 9 and the left and right side surfaces 9d and 9e, the angle formed by the bottom surface 9b of the mold material 9 and the left and right side surfaces 9d and 9e, and the back surface 9c of the mold material 9 and the left and right side surfaces 9d and 9e The left and right side portions A4 and A5 are formed by applying a crease in the longitudinal direction (vertical direction) to the rice ball packaging material A using the angle formed by

左右側部A4,A5は、前記切れ目8a〜8dによって分割された、正面側部A1に隣接する分割片A41,A51、底部A2に隣接する分割片A42,A52、及び背面側部A3に隣接する分割片A43,A53から構成される。
この実施形態では、まず底部A2に隣接する分割片A42,A52を前記短尺方向の折り目で折り曲げ、続いて正面側部A1に隣接する分割片A41,A51、背面側部A3に隣接する分割片A43,A53を前記長尺方向の折り目で折り曲げ、セロハンテープ10等で固定するようにしている。各片が互いに重なった箇所を接着してもよい。前記短尺方向、長尺方向の各折り目は、型材9の角を利用して無理なく折り曲げることができるので、シート状食品4の割れを防止することができる。
The left and right portions A4 and A5 are divided by the cuts 8a to 8d, and are adjacent to the divided pieces A41 and A51 adjacent to the front side A1, the divided pieces A42 and A52 adjacent to the bottom A2, and the rear side A3. It consists of divided pieces A43 and A53.
In this embodiment, first, the divided pieces A42 and A52 adjacent to the bottom A2 are bent at the fold in the short direction, and then the divided pieces A41 and A51 adjacent to the front side A1 and the divided piece A43 adjacent to the back side A3. , A53 is bent at the fold in the longitudinal direction and fixed with cellophane tape 10 or the like. You may adhere | attach the location where each piece overlapped mutually. Since the folds in the short direction and the long direction can be bent without difficulty using the corners of the mold material 9, the sheet-like food 4 can be prevented from cracking.

そして、この型材9に接した箱状のおにぎり用包装材Aの外側から、別のおにぎり用包装材Aを重ねて前述と同様に折り曲げて箱状にして、先に箱状にしたおにぎり用包装材Aを収容した状態にし、さらに別のおにぎり用包装材Aを同様に箱状にして順次重ねていく。箱状のおにぎり用包装材Aは、10枚程度積層されたものとするとよい。型材9はおにぎり用包装材Aの内側に収容された状態のままとすることができる。   Then, from the outside of the box-shaped rice ball packaging material A in contact with the mold material 9, another rice ball packaging material A is stacked and bent in the same manner as described above to form a box shape. The material A is accommodated, and another rice ball packaging material A is similarly boxed and sequentially stacked. About 10 box-shaped rice ball packaging materials A may be laminated. The mold material 9 can be kept in the state of being accommodated inside the onigiri packaging material A.

このようにして嵩低く積層されたおにぎり用包装材の積層体は、保管や輸送の際に場所をとらない。また、積層されていない単体のおにぎり用包装材Aに比べて箱状の形状が損なわれにくく、シート状食品4の割れも防止できる。   Thus, the laminated body of the packaging material for rice balls laminated | stacked low in bulk does not take a space in the case of storage or transportation. In addition, the box-like shape is less likely to be damaged than the single rice ball packaging material A that is not laminated, and the sheet-like food 4 can be prevented from cracking.

このおにぎり用包装材の積層体は、ポリエチレン製等の外袋に収容して保管、輸送することができる。外袋の内部には、おにぎり用包装材Aの底部付近を正面側から背面側にかけて囲むように折れ目を付けたボール紙製等の型材を入れておき、おにぎり用包装材Aが保形されるようにするとよい。このようにすれば、さらにシート状食品4の割れを効果的に防止することができる。
おにぎり用包装材Aは、積層された状態から個別に分離され、その開口部から内部に握り飯が挿入され、正面側部A1及び背面側部A3の互いの上端縁がヒートシール等により接着されることにより、図6に示したようなおにぎり包装体として、コンビニエンスストア等の店舗で販売できる状態となる。この食品包装材を開封するには、まず開封操作片7を指でつまんで引っ張って、外フィルム部1が、その引裂方向に開封操作片7と同一幅で引き裂かれ、中央を境にして左右各部分に分割した状態にする。
This onigiri packaging material laminate can be stored and transported in an outer bag made of polyethylene or the like. Inside the outer bag, a mold material such as a cardboard made of a crease is placed so as to surround the bottom of the onigiri packaging material A from the front side to the back side, and the onigiri packaging material A is shaped. It is good to do so. If it does in this way, the crack of the sheet-like food 4 can be prevented effectively.
The rice ball packaging material A is individually separated from the stacked state, and the rice is inserted into the inside from the opening, and the upper end edges of the front side portion A1 and the back side portion A3 are bonded by heat sealing or the like. By this, as a rice ball package as shown in FIG. 6, it will be in the state which can be sold in stores, such as a convenience store. In order to open the food packaging material, the opening operation piece 7 is first pinched with a finger and pulled, and the outer film portion 1 is torn in the tearing direction in the same width as the opening operation piece 7, and left and right with the center as a boundary. Divide each part.

そして外フィルム部1の左右各部分をそれぞれ外方に引っ張って分離する。この際、包装体の底部A2の左右端部をつまんで引っ張るとよい。すると、内フィルム部2も左右各片2a,2bに分離して、握り飯にシート状食品4が付着した状態のおにぎりがあらわれる。   Then, the left and right portions of the outer film portion 1 are pulled outward to separate them. At this time, the left and right ends of the bottom A2 of the package may be pinched and pulled. Then, the inner film part 2 is also separated into the left and right pieces 2a and 2b, and a rice ball with the sheet-like food 4 attached to the noodles appears.

以上がこの発明の好適な実施形態であるが、この考案は上述の実施形態の構成に限定されるものではなく、形状、寸法、材質等を適宜変更して実施することができる。   The above is the preferred embodiment of the present invention, but the present invention is not limited to the configuration of the above-described embodiment, and can be implemented by appropriately changing the shape, dimensions, material, and the like.
