Description

本発明は、シート状食品と米飯加工食品とを分離状態で包装し、開封時にシート状食品と米飯加工食品とが一体的になる米飯加工食品用包装材及び米飯加工食品包装体に関する。   The present invention relates to a packaged food for cooked rice food and a packaged rice cooked food product in which a sheet-shaped food and a cooked rice processed food are packaged in a separated state, and the sheet-shaped food and the cooked rice processed food are integrated when opened.

従来から、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る米飯加工食品を包装する米飯加工食品用包装材として、シート状食品と米飯加工食品とを分離状態で包装し、開封時にシート状食品と米飯加工食品とが一体的になるように構成されたものが主流となっている。   Traditionally, as a packaged food for processed cooked rice for packaging processed cooked rice sold at supermarkets and convenience stores, etc., sheet food and cooked cooked food are packaged in a separate state, and when opened, sheeted food and cooked rice processed food are used. The mainstream is the one that is configured to be integrated with each other.

かかる米飯加工食品用包装材は、平面視略長方形状をなすとともに一方向（長手方向）と直交する他方向（幅方向）に分割可能に形成される外フィルムと、シート状食品を介して外フィルムに重ね合わされ、外フィルムと同方向に分離可能な内フィルムとを備え、シート状食品を囲むように外フィルムと内フィルムとがシールされている。   Such a packaged food for cooked rice food has a substantially rectangular shape in plan view and an outer film formed so as to be splittable in another direction (width direction) perpendicular to one direction (longitudinal direction) and the sheet-like food. The outer film and the inner film are sealed so as to surround the sheet-like food. The inner film is superposed on the film and is separated from the outer film in the same direction.

前記外フィルムは、一般的に幅方向の中央部で一方向に切断するための切断手段が設けられており、その切断手段で一方向に切断することで幅方向に二分割できるようになっている。他方、前記内フィルムは、外フィルムの幅方向に並列に配置された二枚のフィルムで構成されており、二枚のフィルムが外フィルムと同方向に分離できるようになっている。   The outer film is generally provided with cutting means for cutting in one direction at the center in the width direction, and can be divided into two in the width direction by cutting in one direction with the cutting means. Yes. On the other hand, the inner film is composed of two films arranged in parallel in the width direction of the outer film, and the two films can be separated in the same direction as the outer film.

上記構成の米飯加工食品用包装材は、内フィルム上に米飯加工食品を載置した状態で、外フィルムの一方向で二つ折りにして対向する端部同士をヒートシールすることで、介在する内フィルムによって米飯加工食品とシート状食品とを分離した状態で包装できるようになっている。   The packaged food for cooked rice food having the above-described structure is a state in which the cooked rice cooked food is placed on the inner film, and is folded in two in one direction of the outer film and heat-sealed opposite ends. The processed rice food and sheet-like food can be packaged in a state separated by a film.

そして、該米飯加工食品用包装材は、外フィルムを切断した上で幅方向に引っ張ることで二分割された外フィルム及び内フィルム（二枚のフィルム）がそれぞれ離間（分離）し、シート状食品と米飯加工食品との間にある内フィルム（二枚のフィルム）が抜き取られるようになっている。これにより、開封に併せてシート状食品と米飯加工食品とを一体的にできるようになっている（例えば、特許文献１参照）。
特開２００６−２６４７５８号公報 Then, the packaged food for cooked rice food is obtained by cutting the outer film and pulling it in the width direction so that the outer film and the inner film (two films) separated from each other are separated (separated). The inner film (two films) between the rice and the cooked rice food is extracted. Thereby, the sheet-like food and the cooked rice processed food can be integrated with the opening (see, for example, Patent Document 1).
JP 2006-264758 A

しかしながら、上記構成の米飯加工食品用包装材は、開封時に外フィルムを切断手段で切断した上で幅方向に引っ張らなければ開封することができず、開封作業が繁雑である。また、かかる米飯加工食品用包装材は、開封後にシート状食品と一体的になった米飯加工食品を直接手掴みしなければならず、該米飯加工食品を食する人の手が汚れているときに不衛生であるといった問題もある。   However, the packaged food for cooked rice processed food having the above structure cannot be opened unless it is pulled in the width direction after the outer film is cut by a cutting means at the time of opening, and the opening operation is complicated. In addition, such packaged food for cooked rice must directly grip the cooked cooked food integrated with the sheet-shaped food after opening, and the hand of the person eating the cooked cooked food is dirty There are also problems such as being unsanitary.

そこで、本発明は、斯かる実情に鑑み、開封時に分断することなく引っ張るだけでシート状食品と米飯加工食品とを一体的にして開封することができ、しかも、シート状食品と一体的になった米飯加工食品を直接手掴みすることなく、衛生的に米飯加工食品を食することのできる米飯加工食品用包装材及び米飯加工食品包装体を提供することを課題とする。   Therefore, in view of such circumstances, the present invention can be integrated to open the sheet-shaped food and the cooked rice food by simply pulling without breaking at the time of opening, and is integrated with the sheet-shaped food. It is an object of the present invention to provide a packaged food for cooked rice food and a packaged rice cooked food product that can eat the cooked cooked food hygienically without directly grasping the cooked cooked rice food.

本発明に係る米飯加工食品用包装材は、シート状食品と米飯加工食品とを分離状態で包装可能に構成されるとともに、包装したシート状食品と米飯加工食品とを一体的にして開封可能に構成された米飯加工食品用包装材において、平面視略四角形状をなす外フィルム部と、外フィルム部の一方向に対して直交する他方向に並列をなして互いの先端部を付き合わすとともに各基端が外フィルム部の両側端に分離可能に接続された一対の第一内フィルム部と、各第一内フィルム部の先端から延出し、第一内フィルム部との境界に折曲稜線を形成するように先端を外側にして折り返された一対の第二内フィルム部とを備え、外フィルム部と第一内フィルム部との間にシート状食品が介設され、外フィルム部及び第一内フィルム部は、外フィルム部の一方向の両端部同士が剥離可能にシールされてなり、米飯加工食品を包み込むように第二内フィルム部を内側にして外フィルム部の一方向で二つ折りにするとともに対向する第二内フィルム部の端部同士をシールすることで米飯加工食品を包装するように構成されていることを特徴とする。なお、ここで「先端部を付き合わす」とは、先端同士が接触状態で対向することは勿論のこと、先端部分が重ね合わさることも含む概念で、「シール」とは、ヒートシールや超音波シールによる溶着は勿論のこと、接着剤を介しての接着も含むものである。   The packaging material for cooked rice processed food according to the present invention is configured so that the sheet-shaped food and the cooked rice processed food can be packaged in a separated state, and the packaged sheet-shaped food and the cooked rice processed food can be opened integrally. In the configured cooked rice food packaging material, each of the outer film part having a substantially square shape in plan view and the other film part in parallel with each other perpendicular to one direction of the outer film part are attached to each other and attached to each other. A pair of first inner film portions whose base ends are separably connected to both side ends of the outer film portion, and the first inner film portions extend from the distal ends, and a bent ridge line is formed at the boundary between the first inner film portions. A pair of second inner film portions that are folded back with the leading ends outward, and a sheet-like food is interposed between the outer film portion and the first inner film portion. The inner film part is the outer film part. Both ends of the direction are sealed so as to be peelable, and the second inner film part is folded in half in one direction of the outer film part with the second inner film part inside so as to wrap the cooked rice processed food. It is characterized by packaging the cooked rice processed food by sealing the ends. Here, “attaching the tip” means not only that the tips are opposed to each other in contact, but also that the tips are overlapped. “Seal” means heat sealing or ultrasonic This includes not only welding by a seal but also adhesion via an adhesive.

上記構成の米飯加工食品用包装材によれば、米飯加工食品を包装した状態で第一内フィルム部及び第二内フィルム部がシート状食品と米飯加工食品との間に介在することになるので、シート状食品と米飯加工食品とを分離させた状態にすることができ、米飯加工食品の水分がシート状食品に到達して味や食感などを低下させてしまうのを防止することができる。   According to the packaging material for cooked rice processed food having the above configuration, the first inner film portion and the second inner film portion are interposed between the sheet-like food and the cooked rice processed food in a state where the cooked rice processed food is packaged. The sheet-like food and the cooked rice processed food can be separated from each other, and the moisture of the cooked rice processed food can be prevented from reaching the sheet-like food and deteriorating the taste and texture. .

そして、該米飯加工食品用包装材は、米飯加工食品を包装した状態で各第二内フィルム部の先端側を互いに離間する方向に引っ張ると、第一内フィルム部と第二内フィルム部との境界にある折曲稜線が第一内フィルム部の先端側から基端側に移行する。すなわち、一対の第二内フィルム部の先端部を引っ張ると、第一内フィルム部と第二内フィルム部との境界に形成されていた折曲稜線が第一内フィルム部内で先端側から基端側に移行し、互いに付き合わせた各第一内フィルム部の先端側が第二内フィルム部の移動（引っ張り）に追従して外側に引き出されることになる。   And when this rice cooked food packaging material is pulled in the direction which mutually separates the tip side of each 2nd inner film part in the state which packed the cooked rice processed food, it is the 1st inner film part and the 2nd inner film part. The bent ridge line at the boundary moves from the distal end side to the proximal end side of the first inner film portion. That is, when the distal end portions of the pair of second inner film portions are pulled, the bent ridge line formed at the boundary between the first inner film portion and the second inner film portion is the proximal end from the distal end side in the first inner film portion. The leading end sides of the first inner film portions that are attached to each other follow the movement (pulling) of the second inner film portion and are pulled out to the outside.

これにより、一対の第一内フィルム部及び一対の第二内フィルム部によって、米飯加工食品と分離していたシート状食品が一対の第一内フィルム部（第二内フィルム部）間から露呈して米飯加工食品と一体化することになる。   Thereby, the sheet-like food separated from the cooked rice processed food is exposed between the pair of first inner film portions (second inner film portions) by the pair of first inner film portions and the pair of second inner film portions. Will be integrated with processed rice food.

そして、シート状食品と米飯加工食品との一体化に合わせて、一対の第二内フィルム部に対する引っ張り作用で、剥離可能にシールされた外フィルム部、及び第一内フィルム部の両端部が剥離した後、最終的に外フィルム部の側端から一対の第一フィルム部の基端が分離し、第一内フィルム部及び第二内フィルム部が外フィルム部から切り離されることになる。そうすると、シート状食品と一体的になった米飯加工食品周りに略二つ折りの外フィルム部だけが残ることになる。これにより、外フィルム部を介してシート状食品と一体化した米飯加工食品を手掴みすることができる。   And in accordance with the integration of the sheet-like food and the cooked rice processed food, the outer film part that is peelably sealed by the pulling action on the pair of second inner film parts, and both ends of the first inner film part are peeled off. After that, the base ends of the pair of first film portions are finally separated from the side ends of the outer film portion, and the first inner film portion and the second inner film portion are separated from the outer film portion. If it does so, only the substantially two-fold outer film part will remain around the cooked rice processed food united with the sheet-like food. Thereby, the cooked rice processed food integrated with the sheet-like food can be grasped by hand through the outer film portion.

本発明の一態様として、第二内フィルム部の先端部が、第一内フィルム部の基端よりも外側に延出していることが好ましい。かかる米飯加工食品用包装材は、米飯加工食品を包装した状態で、各第二内フィルム部が外フィルム部及び第一内フィルム部の内側で二つ折りにされた状態になるので、上述のように第二内フィルム部の先端部が、第一内フィルム部の基端よりも外側に延出していると、開封時に第二内フィルム部の端部を把持し易くなり、開封時の操作性がより向上する。   As one aspect of the present invention, it is preferable that the distal end portion of the second inner film portion extends outward from the proximal end of the first inner film portion. Such a packaged food for cooked rice food is in a state in which the cooked rice cooked food is packaged, and each second inner film portion is folded in half inside the outer film portion and the first inner film portion. If the tip of the second inner film part extends outside the base end of the first inner film part, it becomes easier to grip the end part of the second inner film part during opening, and operability during opening Will be improved.

本発明の他態様として、外フィルム部の側端部に第一内フィルム部の基端部が剥離可能にシールされることで、第一内フィルム部の基端が外フィルム部の側端に分離可能に接続されていることが好ましい。このようにすれば、開封時における他方向への引っ張り力で外フィルム部の側端部から第一フィルム部の基端部が剥離されるので、これらを円滑に分離させることができる。   As another aspect of the present invention, the base end portion of the first inner film portion is peelably sealed to the side end portion of the outer film portion so that the base end of the first inner film portion is at the side end of the outer film portion. It is preferable that they are connected in a separable manner. If it does in this way, since the base end part of the 1st film part will peel from the side edge part of an outer film part by the pulling force to the other direction at the time of opening, these can be separated smoothly.

また、一対の第一内フィルム部の先端部同士が剥離可能に一方向にシールされていることが好ましい。このようにすれば、一対の第一内フィルム部間が閉塞されるので、米飯加工食品を包装した状態で、その水分が第一内フィルム部間を介してシート状食品に到達してしまうのを確実に防止することができる。これにより、シート状食品の味や食感などを低下させてしまうことをより確実に防止することができる。   Moreover, it is preferable that the front-end | tip parts of a pair of 1st inner film part are sealed in one direction so that peeling is possible. If it does in this way, between a pair of 1st inner film parts will be obstruct | occluded, In the state which packed the cooked rice processed food, the water | moisture content will reach | attain a sheet-like food via between 1st inner film parts. Can be reliably prevented. Thereby, it can prevent more reliably that the taste, food texture, etc. of a sheet-like food are reduced.

そして、第二内フィルム部は、少なくとも米飯加工食品と対向する面にエンボス加工が施されていることが好ましい。このようにすれば、開封時に生じる第二内フィルム部と米飯加工食品との間の抵抗が小さくなり、米飯加工食品を型くずれさせることなく容易に開封することができる。   And as for the 2nd inner film part, it is preferable that the embossing is given to the surface facing at least cooked rice processed food. If it does in this way, the resistance between the 2nd inner film part produced at the time of opening and the cooked rice processed food will become small, and it can open easily, without making the cooked rice processed food out of shape.

そして、本発明に係る米飯加工食品包装体は、米飯加工食品が上記何れかの米飯加工食品用包装材で包装されていることを特徴とする。かかる米飯加工食品包装体は、上記何れかの米飯加工食品用包装材を用いて米飯加工食品が包装されているので、上述の如く、第二内フィルム部を引っ張ることでシート状食品と米飯加工食品とを一体的にして開封することができる上に、開封状態において外フィルムを介して米飯加工食品を手掴みできる状態にすることができる。   The cooked rice processed food package according to the present invention is characterized in that the cooked rice processed food is packaged with any one of the above-described cooked rice processed food packaging materials. Since the cooked rice processed food package is packaged with any of the above-described cooked rice processed food packaging materials, the sheet-like food and cooked rice processed by pulling the second inner film portion as described above. The food can be opened integrally with the food, and the cooked rice processed food can be grasped by hand through the outer film in the opened state.

以上のように、本発明に係る米飯加工食品用包装材及び米飯加工食品包装体によれば、開封時に分断することなく引っ張るだけでシート状食品と米飯加工食品とを一体的にして開封することができ、しかも、シート状食品と一体的になった米飯加工食品を直接手掴みすることなく、衛生的に米飯加工食品を食することができるという優れた効果を奏し得る。   As described above, according to the cooked rice processed food packaging material and the cooked rice processed food packaging body according to the present invention, the sheet-like food and the cooked rice processed food can be opened together by simply pulling without breaking during opening. In addition, it is possible to produce an excellent effect that the cooked rice processed food can be eaten hygienically without directly grasping the cooked rice processed food integrated with the sheet-like food.

以下、本発明の一実施形態に係る米飯加工食品用包装材及び米飯加工食品包装体について、添付図面を参照しつつ説明する。   Hereinafter, the cooked rice processed food packaging material and the cooked rice processed food package according to an embodiment of the present invention will be described with reference to the accompanying drawings.

The length is set to be longer than the protruding amount, and the end portions extend outward from the base ends of the first inner film portions 20 and 20.

本実施形態に係る米飯加工食品用包装材１は、図３（ａ）〜図３（ｅ）に示す如く、外フィルム部１０、第一内フィルム部２０，２０、及び第二内フィルム部３０，３０が一枚の樹脂フィルムＦに対して曲げ加工、シール加工、切断加工を行うことで形成されている。より具体的に説明すると、米飯加工食品用包装材１を形成するための樹脂フィルムＦは、平面視略長方形状に形成されており、図３（ａ）に示す如く、長手方向の長さが、外フィルム部１０の幅方向の長さ、一対の第一内フィルム部２０，２０の合計延出量、一対の第二内フィルム部３０，３０の合計延出量、後述する一対の切除領域（切除代）１０ａ’の合計長さを合計した長さに設定され、長手方向と直交する短手方向の長さが外フィルム部１０の長手方向の長さに設定されている。   The cooked rice processed food packaging material 1 according to the present embodiment includes an outer film part 10, first inner film parts 20, 20, and a second inner film part 30, as shown in FIGS. 3 (a) to 3 (e). , 30 are formed by bending, sealing, and cutting a single resin film F. More specifically, the resin film F for forming the packaging material 1 for cooked rice processed food is formed in a substantially rectangular shape in plan view, and has a length in the longitudinal direction as shown in FIG. , The length in the width direction of the outer film part 10, the total extension amount of the pair of first inner film parts 20, 20, the total extension amount of the pair of second inner film parts 30, 30, a pair of cut areas described later (Removal allowance) The total length of 10 a ′ is set to the total length, and the length in the short direction perpendicular to the longitudinal direction is set to the length in the longitudinal direction of the outer film portion 10.

そして、該樹脂フィルムＦは、短手方向の延びる中心線を含む中央の領域（樹脂フィルムＦの長手方向で外フィルム部１０の幅方向の長さに設定された領域）が、前記外フィルム部１０となる第一領域１０’に設定されるとともに、第一領域１０’の両側で隣接する所定幅の領域が後の工程で第一領域１０’と後述の第二領域２０’，２０’とを分離するための切除領域１０ａ’，１０ａ’に設定され、各切除領域１０ａ’，１０ａ’の両側で隣接する所定領域（樹脂フィルムＦの長手方向で第一内フィルム部２０，２０の延出量に相当する長さに設定された領域）が第一内フィルム部２０，２０となる第二領域２０’，２０’に設定され、各二領域２０’，２０’に隣接する該樹脂フィルムＦの両端の所定領域（樹脂フィルムＦの長手方向で第二内フィルム部３０，３０の延出量に相当する長さに設定された領域）が第二内フィルム部３０，３０となる第三領域３０’，３０’に設定されている。すなわち、該樹脂フィルムＦは、外フィルム部１０となる第一領域１０’を挟んで第一内フィルム部２０，２０となる一対の第二領域２０’，２０’、一対の切除領域２０ａ’，２０ａ及び第二内フィルム部３０，３０となる一対の第三領域３０’，３０’が対称的に設定されている。なお、以下の説明において、第一領域１０’と切除領域１０ａ’との境界を第一境界Ｌ１といい、切除領域１０ａ’と第二領域２０’との境界を第二境界Ｌ２といい、第二領域２０’と第三領域３０’との境界を第三境界Ｌ３ということとする。   And as for this resin film F, the center area | region (area | region set to the length of the width direction of the outer film part 10 in the longitudinal direction of the resin film F) including the centerline extended in a transversal direction is the said outer film part. The first region 10 ′ is set to 10 and a region having a predetermined width adjacent to both sides of the first region 10 ′ is a first region 10 ′ and later-described second regions 20 ′ and 20 ′. The predetermined regions (extensions of the first inner film portions 20 and 20 in the longitudinal direction of the resin film F) that are set in the excision regions 10a ′ and 10a ′ and are separated on both sides of the excision regions 10a ′ and 10a ′. The resin film F adjacent to each of the two regions 20 ′ and 20 ′ is set in the second regions 20 ′ and 20 ′ which are the first inner film portions 20 and 20. Predetermined regions at both ends (the longitudinal direction of the resin film F) Third region 30 second in extension is set to a length corresponding to the amount of area of the film 30, 30) is the second inner film 30, 30 ', 30' are set to. That is, the resin film F includes a pair of second regions 20 ′, 20 ′, a pair of cut regions 20a ′, which become the first inner film portions 20, 20 across the first region 10 ′, which becomes the outer film portion 10. A pair of third regions 30 ′ and 30 ′ to be 20 a and the second inner film portions 30 and 30 are set symmetrically. In the following description, the boundary between the first region 10 ′ and the excision region 10a ′ is referred to as a first boundary L1, the boundary between the excision region 10a ′ and the second region 20 ′ is referred to as a second boundary L2, The boundary between the two regions 20 ′ and the third region 30 ′ is referred to as a third boundary L3.

そして、本実施形態に係る樹脂フィルムＦは、一方の面Ｅにエンボス加工が施されるとともにイージーピール性（剥離容易性）が付与されている（以下、このイージーピール性の付与された面をイージーピール面という）。ここでイージーピール性とは、ヒートシールや超音波シールによる溶着や、接着剤を介しての接着によって接合させた部位の接続強度を弱めて剥離し易くした特性をいい、本実施形態においては、ヒートシールを前提にしてイージーピール性が付与されている。   And the resin film F which concerns on this embodiment is embossed on one surface E, and the easy peel property (easiness of peeling) is provided (henceforth this surface provided with the easy peel property). Easy peel side). Here, the easy peel property refers to the property of facilitating peeling by weakening the connection strength of the part joined by welding through heat sealing or ultrasonic sealing, or adhesion through an adhesive, and in this embodiment, Easy peel properties are provided on the premise of heat sealing.

そして、樹脂フィルムＦに対するイージーピール性の付与は、少なくとも一方の面Ｅにシールに対するイージーピール性（剥離性）に優れたイージーピール層が形成されたイージーピールフィルムで樹脂フィルムＦを構成したり、樹脂フィルムＦの表面にパートコートを施したり、樹脂フィルムＦの表面を粗面にしたりすることで行うことができる。   And the provision of the easy peel property to the resin film F is to constitute the resin film F with an easy peel film in which an easy peel layer excellent in the easy peel property (peelability) to the seal is formed on at least one surface E. The surface of the resin film F can be part-coated, or the surface of the resin film F can be roughened.

上記条件の樹脂フィルムＦから米飯加工食品用包装材１を作製するには、まず、図３（ｂ）に示す如く、樹脂フィルムＦの両端にある第三領域３０’、３０’を第三境界Ｌ３でイージーピール面Ｅとは反対側に折り返す。しかる後、図３（ｃ）に示す如く、第一領域１０’のイージーピール面Ｅ側にシート状食品Ａを配置する。   In order to produce the cooked rice food packaging material 1 from the resin film F under the above conditions, first, as shown in FIG. 3B, the third regions 30 ′ and 30 ′ at both ends of the resin film F are separated from the third boundary. At L3, it is folded back to the opposite side from the easy peel surface E. Thereafter, as shown in FIG. 3C, the sheet-like food A is disposed on the easy peel surface E side of the first region 10 '.

そして、図３（ｄ）に示す如く、第一境界Ｌ１と第二境界Ｌ２が重なるように切断領域１０ａ’を二つ折りにして、第二領域２０’、２０’をイージーピール面Ｅ側に折返し、第三境界Ｌ３（折曲稜線Ｌ）を互いに付き合わせた状態にする。この状態で、第一領域１０’のイージーピール面Ｅと第二領域２０’，２０’のイージーピール面Ｅとが対向し、付き合わせた第三境界Ｌ３，Ｌ３同士もイージーピール面Ｅが対向した状態となる。また、第二領域２０’，２０’のイージーピール面Ｅの反対面と第三領域３０’，３０’のイージーピール面Ｅの反対面とが対向した状態、すなわち、第三領域３０’，３０’のイージーピール面Ｅが外側に向いた状態となる。   Then, as shown in FIG. 3D, the cut region 10a ′ is folded in half so that the first boundary L1 and the second boundary L2 overlap, and the second regions 20 ′ and 20 ′ are folded back to the easy peel surface E side. The third boundary L3 (the bent ridge line L) is brought into a state of being attached to each other. In this state, the easy peel surface E of the first region 10 ′ and the easy peel surface E of the second regions 20 ′ and 20 ′ are opposed to each other, and the easy peel surface E is also opposed to the third boundaries L3 and L3. It will be in the state. Further, the opposite surface of the easy peel surface E of the second regions 20 ′, 20 ′ and the opposite surface of the easy peel surface E of the third regions 30 ′, 30 ′ face each other, that is, the third regions 30 ′, 30. 'Easy peel surface E' faces outward.

そして、図３（ｅ）に示す如く、二つ折りにされた切除領域１０ａ’近傍で第一領域１０’と第二領域２０’とを所定幅で剥離可能にヒートシールした後、切除領域１０ａ’を第一境界Ｌ１及び第二境界Ｌ２に沿って切除する。これによって分断された第一領域１０’と第二領域２０’、２０’とがシールによって接続された状態になる。そして、樹脂フィルムＦの短手方向である第一領域１０’の両端部と各第二領域２０’，２０’の両端部とを所定幅でヒートシールし、シート状食品Ａを包囲した所定幅のシールラインＳを形成するとともに、互いに付き合わせた第三境界Ｌ３をその境界Ｌ３に沿ってヒートシールして線状のシールラインＳＬを形成し、第三境界Ｌ３を剥離可能に接合させる。   Then, as shown in FIG. 3 (e), the first region 10 ′ and the second region 20 ′ are heat-sealed with a predetermined width in the vicinity of the half-cut resection region 10a ′, and then the resection region 10a ′. Are cut along the first boundary L1 and the second boundary L2. As a result, the divided first region 10 ′ and second regions 20 ′ and 20 ′ are connected by a seal. And the both ends of 1st area | region 10 'which is the transversal direction of the resin film F, and the both ends of each 2nd area | region 20' and 20 'are heat-sealed by predetermined width, and the predetermined width which surrounded the sheet-like food A In addition, the third boundary L3 attached to each other is heat-sealed along the boundary L3 to form a linear seal line SL, and the third boundary L3 is detachably joined.

これにより、第一領域１０’が外フィルム部１０になり、各第二領域２０’，２０’が各第一内フィルム部２０，２０になり、各第三領域３０’，３０’が第二内フィルム部３０，３０になる。また、外フィルム部１０の長手方向の両端部とこれに対向する第一内フィルム部２０，２０の両端部とが剥離可能にシールされた状態にもなる。   Thereby, 1st area | region 10 'becomes the outer film part 10, each 2nd area | region 20', 20 'becomes each 1st inner film part 20, 20, and each 3rd area | region 30', 30 'becomes 2nd. It becomes the inner film part 30,30. Moreover, it will also be in the state by which the both ends of the longitudinal direction of the outer film part 10 and the both ends of the 1st inner film parts 20 and 20 facing this were peeled and sealed.

上記構成の米飯加工食品用包装材１は、図４〜図７に示す如く、第二内フィルム部３０，３０が内側にして米飯加工食品Ｂを包み込むように外フィルム部１０の長手方向で二つ折りにし、これによって対向する第二内フィルム部３０，３０の端部同士をシールすることで米飯加工食品Ｂを包装するようになっている。すなわち、該米飯加工食品用包装材１は、一対の第二内フィルム部３０，３０上に米飯加工食品Ｂを載置した上で、一対の第二内フィルム部３０，３０を内側にして外フィルム部１０の長手方向で二つ折りにし、第二内フィルム部３０，３０の対向する端部同士を所定幅のシールラインＳ’を形成するようにヒートシールすることで、シート状食品Ａと米飯加工食品Ｂとが分離した状態で包装するようになっている。このように米飯加工食品Ｂを包装することで、米飯加工食品Ｂが上記構成の米飯加工食品用包装材１で包装された米飯加工食品包装体Ｘとなる。   As shown in FIGS. 4 to 7, the packaged food 1 for cooked rice food having the above-described configuration is arranged in the longitudinal direction of the outer film portion 10 so that the second inner film portions 30, 30 wrap the cooked rice processed food B inside. The rice cooked food B is packaged by folding it and sealing the ends of the opposing second inner film portions 30 and 30 with each other. That is, the cooked rice processed food packaging material 1 is placed on the pair of second inner film portions 30, 30 with the cooked rice processed food B placed on the pair of second inner film portions 30, 30. The sheet-like food A and cooked rice are folded in half in the longitudinal direction of the film part 10 and heat-sealed so that the opposing ends of the second inner film parts 30 and 30 form a seal line S ′ having a predetermined width. The processed food B is packaged in a separated state. By packaging the cooked rice processed food B in this way, the cooked rice processed food B is packaged with the cooked cooked food packaging material 1 having the above-described configuration.

そして、米飯加工食品包装体Ｘを開封する場合、米飯加工食品用包装材１の両側端となる一対の第二内フィルム部３０，３０の先端部を離間させるように引っ張ると、その引っ張り力が第二内フィルム部３０，３０を介して第一内フィルム部２０，２０の先端側に作用し、図８（ａ）に示す如く、ヒートシールされた一対の第一内フィルム部２０，２０の先端が剥離することになる。また、これに併せて、図９（ａ）に示す如く、外フィルム部１０にシールされた一対の第一内フィルム部２０，２０の長手方向の両端部についても、該外フィルム部１０の中央側から剥離することになる。   And when opening the cooked rice processed food packaging body X, if it pulls so that the front-end | tip part of a pair of 2nd inner film parts 30 and 30 used as the both ends of the packaging material 1 for cooked rice processed foods may be separated, the tensile force will be It acts on the front end side of the first inner film part 20, 20 via the second inner film part 30, 30, and as shown in FIG. 8A, the heat-sealed pair of first inner film parts 20, 20 The tip will peel off. In addition to this, as shown in FIG. 9A, the longitudinal ends of the pair of first inner film portions 20 and 20 sealed by the outer film portion 10 are also centered on the outer film portion 10. It will peel from the side.

そして、第二内フィルム部３０，３０に対する引っ張り作用で、図８（ｂ）、及び図９（ｂ）に示す如く、第一内フィルム部２０，２０と第二内フィルム部３０，３０との境界にある折曲稜線Ｌが第一内フィルム部２０，２０の先端側から基端側に移行しつつ、第一内フィルム部２０，２０の先端側が第二内フィルム部３０，３０に引かれて外側に引き出されることになる。   And, as shown in FIG. 8 (b) and FIG. 9 (b), the first inner film portions 20, 20 and the second inner film portions 30, 30 are pulled by the pulling action on the second inner film portions 30, 30. While the bent ridge line L at the boundary is shifted from the distal end side of the first inner film portion 20, 20 to the proximal end side, the distal end side of the first inner film portion 20, 20 is drawn to the second inner film portion 30, 30. Will be pulled out.

このように一対の第一内フィルム部２０，２０が外側に引き出されることで、一対の第一内フィルム部２０，２０間の間隔が広がって、米飯加工食品Ｂの収容された領域にシート状食品Ａが露呈することになる。そして、図８（ｃ）、図９（ｃ）及び図１０（ａ）に示す如く、米飯加工食品Ｂとシート状食品Ａとの間から第一内フィルム部２０，２０が基端部近傍まで引き出されると、シート状食品Ａと米飯加工食品Ｂとが一体化し、さらに、引っ張ることで第一内フィルム部２０，２０の基端部が外フィルム部１０の側端部から剥離することになる。   Thus, a space | interval between a pair of 1st inner film parts 20 and 20 spreads by drawing a pair of 1st inner film parts 20 and 20 outside, and it is a sheet form in the area | region in which the cooked rice processed food B was accommodated. Food A will be exposed. And as shown in Drawing 8 (c), Drawing 9 (c), and Drawing 10 (a), between the cooked rice processed food B and sheet-like food A to the 1st inner film parts 20 and 20 near the base end part When pulled out, the sheet-shaped food A and the cooked rice processed food B are integrated, and further, the base end portions of the first inner film portions 20 and 20 are peeled off from the side end portions of the outer film portion 10 by pulling. .

そうすると、図１０（ｂ）に示す如く、第一内フィルム部２０，２０及び第二内フィルム部３０，３０が外フィルム部１０から分離され、図１０（ｃ）に示す如く、残った外フィルム部１０が二つ折りになった状態でシート状食品Ａと一体的になった米飯加工食品Ｂを包み込んだ状態になる。これにより、外フィルム部１０を介してシート状食品Ｂと一体的になった米飯加工食品Ａを手掴みすることができ、手が汚れていても衛生的に米飯加工食品Ａを食することができる。   Then, as shown in FIG. 10 (b), the first inner film portions 20, 20 and the second inner film portions 30, 30 are separated from the outer film portion 10, and the remaining outer film as shown in FIG. 10 (c). It will be in the state which wrapped the cooked rice processed food B integrated with the sheet-like food A in the state in which the part 10 was folded in half. Thereby, the cooked rice processed food A integrated with the sheet-like food B can be grasped by hand through the outer film part 10, and the cooked cooked rice A can be eaten hygienically even if the hands are dirty. it can.

以上のように、本実施形態に係る米飯加工食品用包装材１は、米飯加工食品Ｂを包装した状態から第二内フィルム部３０，３０の両端を互いに離間する方向に引っ張るだけで、米飯加工食品Ｂと分離していたシート状食品Ａと米飯加工食品Ｂとを一体化することができ、さらに、外フィルム部１０を介し、シート状食品Ａと一体化した米飯加工食品Ｂを手掴みできる状態にすることができる。   As described above, the rice cooked food packaging material 1 according to the present embodiment is simply processed by pulling both ends of the second inner film portions 30 and 30 away from the state in which the cooked rice processed food B is packaged. The sheet-like food A and the cooked rice processed food B separated from the food B can be integrated, and further, the cooked rice processed food B integrated with the sheet-like food A can be grasped by the outer film portion 10. Can be in a state.

そして、第二内フィルム部３０，３０の先端部を第一内フィルム部２０，２０の基端よりも外側に延出させることで、開封時に第二内フィルム部３０，３０の端部が把持しやすく、開封がより簡単である。   And the edge part of the 2nd inner film part 30 and 30 hold | grips at the time of opening by extending the front-end | tip part of the 2nd inner film part 30 and 30 outside the base end of the 1st inner film part 20 and 20 Easy to open and easier to open.

さらに、一対の第二内フィルム部３０，３０の米飯加工食品Ｂと対向する面にエンボス加工を施したので、開封時に生じる第二内フィルム部３０，３０と米飯加工食品Ｂとの間の抵抗が小さくなり、米飯加工食品Ｂを型くずれさせることなく容易に開封することができる。   Furthermore, since the embossing was performed on the surface of the pair of second inner film portions 30 and 30 facing the cooked rice processed food B, the resistance between the second inner film portions 30 and 30 and the cooked rice processed food B generated at the time of opening. Can be easily opened without causing the cooked rice processed food B to lose its shape.

また、一対の第一内フィルム部２０，２０の先端部同士が剥離可能にヒートシールされているので、米飯加工食品Ｂを包装した状態で、米飯加工食品Ｂの水分が第一内フィルム部２０，２０間を介してシート状食品Ａに到達してしまうのを防止することができる。これにより、シート状食品Ａの食感を害することなく包装することができる。   Moreover, since the front-end | tip parts of a pair of 1st inner film parts 20 and 20 are heat-sealed so that peeling is possible, the water | moisture content of the cooked rice processed food B is the 1st inner film part 20 in the state which packaged the cooked rice processed food B. , 20 can be prevented from reaching the sheet-like food A. Thereby, it can package, without harming the food texture of the sheet-like food A.

そして、一枚の樹脂フィルムＦに対して曲げ加工、シール加工、切断加工を行うことで外フィルム部１０、第一内フィルム部２０，２０、及び、第二内フィルム部３０，３０を形成するようにしているので、簡単に製造することができる。   And the outer film part 10, the 1st inner film parts 20 and 20, and the 2nd inner film parts 30 and 30 are formed by performing a bending process, a sealing process, and a cutting process with respect to the resin film F of 1 sheet. Therefore, it can be manufactured easily.

尚、本発明の米飯加工食品用包装材は、上記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。   In addition, the packaging material for cooked rice processed foods of this invention is not limited to the said embodiment, Of course, a various change can be added in the range which does not deviate from the summary of this invention.

上記実施形態において、一枚の樹脂フィルムＦから外フィルム部１０、一対の第一内フィルム部２０，２０、及び第二内フィルム部３０，３０を形成するようにしたが、これに限定されるものではなく、例えば、枚葉状をなす複数枚のフィルム片を接続して外フィルム部１０等を形成するようにしてもよい。   In the above embodiment, the outer film part 10, the pair of first inner film parts 20, 20, and the second inner film parts 30, 30 are formed from a single resin film F. However, the present invention is not limited to this. For example, the outer film portion 10 or the like may be formed by connecting a plurality of film pieces having a sheet shape.

具体的には、図１１に示す如く、折曲稜線Ｌを介して接続された第一内フィルム部２０と第二内フィルム部３０とを形成するように二つ折りにした樹脂フィルムＦａ，Ｆｂを二枚作製し、その二枚の樹脂フィルムＦａ，Ｆｂをそれぞれの折曲稜線Ｌを付き合わせるように配置するとともに、各樹脂フィルムＦａ，Ｆｂの一方の片（第一内フィルム部２０に相当）にシート状食品Ａを介して外フィルム部１０となる長方形状の樹脂フィルムＦｃを重ね合わせ、シート状食品Ａを包囲するように一方の片と外フィルム部１０となる樹脂フィルムＦｃとを剥離可能にヒートシールするようにしてもよい。この種の米飯加工食品用包装材は、一般的に外フィルム部１０に対して商品名や商品イメージ等の印刷が施されるものであるが、商品仕様の変更（例えば、米飯加工食品Ｂ内の具の変更）や価格の変更等に伴って印刷内容が変更されることがあり、印刷内容の変更を行うに際して変更前の内容を印刷した米飯加工食品用包装材全体を廃棄しなければならない場合がある。しかしながら、上述の如く、印刷の対象となる外フィルム部１０を別個独立に構成しておけば、印刷の変更があっても外フィルム部１０のみに対する印刷作業や廃棄だけでよく、印刷内容の変更に伴う無駄を最小限に抑えることができる。   Specifically, as shown in FIG. 11, resin films Fa and Fb folded in two so as to form a first inner film portion 20 and a second inner film portion 30 connected via a bent ridge line L are formed. Two sheets are produced, and the two resin films Fa and Fb are arranged so that the respective bent ridge lines L are associated with each other, and one piece of each resin film Fa and Fb (corresponding to the first inner film portion 20). A rectangular resin film Fc that becomes the outer film portion 10 is overlaid on the sheet-like food A, and one piece and the resin film Fc that becomes the outer film portion 10 can be peeled so as to surround the sheet-like food A You may make it heat-seal. This kind of packaged food for cooked rice is generally printed on the outer film part 10 with a product name, product image, etc., but the product specifications are changed (for example, in the cooked rice processed food B). The contents of the printing may be changed due to changes in price and price, etc., and when changing the contents of printing, the entire cooked rice packaging material printed with the contents before the change must be discarded. There is a case. However, as described above, if the outer film unit 10 to be printed is configured separately and independently, it is only necessary to print or discard only the outer film unit 10 even if the printing is changed. Can be minimized.

また、上記実施形態において、外フィルム部１０と第一フィルム部２０，２０とを所定幅で剥離可能にシールし、開封時に外フィルム部１０から第一フィルム部２０，２０を分離できるようにしたが、例えば、一枚のフィルムを曲げ加工して外フィルム部１０、第一内フィルム部２０，２０及び第二内フィルム部３０，３０を連続的に形成するとともに、外フィルム部１０と第一内フィルム部２０，２０との境界に切断補助線（例えば、ミシン目やハーフカット等）を設け、開封時に切断補助線で破断することで外フィルム部１０と第一内フィルム部２０，２０とを分離できるようにしてもよい。   Moreover, in the said embodiment, the outer film part 10 and the 1st film part 20 and 20 were sealed so that peeling was possible by predetermined width, and it enabled it to isolate | separate the 1st film part 20 and 20 from the outer film part 10 at the time of opening. However, for example, the outer film part 10, the first inner film parts 20 and 20, and the second inner film parts 30 and 30 are continuously formed by bending a single film, and the outer film part 10 and the first film A cutting auxiliary line (for example, a perforation or a half cut) is provided at the boundary between the inner film parts 20 and 20, and the outer film part 10 and the first inner film parts 20 and 20 May be separable.

このようにしても、第一内フィルム部２０，２０を外フィルム部１０から分離させることができ、上記実施形態と同様の作用及び効果を奏することができる。なお、この場合においては、切断補助線で円滑に切断できるようにするために、外フィルム部１０の一方向の少なくとも何れか一方の端部（切断補助線の端部）において、外フィルム部１０と第一フィルム部２０，２０との境界上にノッチや切欠き等を設けておくことが好ましい。また、この場合、外フィルム部１０及び第一内フィルム部２０，２０は、既に接続された態様となるので、必ずしも外フィルム部１０の側端部と第一内フィルム部２０，２０の基端部とを所定幅でヒートシールする必要はないことは言うまでもない。   Even if it does in this way, the 1st inner film parts 20 and 20 can be separated from the outer film part 10, and there can exist an effect | action and effect similar to the said embodiment. In this case, in order to enable smooth cutting with the auxiliary cutting line, the outer film part 10 is at least at one end (one end of the auxiliary cutting line) in one direction of the outer film part 10. It is preferable to provide a notch or a notch on the boundary between the first film portion 20 and the first film portion 20. In this case, since the outer film portion 10 and the first inner film portions 20 and 20 are already connected, the side end portions of the outer film portion 10 and the proximal ends of the first inner film portions 20 and 20 are not necessarily provided. Needless to say, it is not necessary to heat-seal the parts with a predetermined width.

また、外フィルム部１０の側端部に第一内フィルム部２０の基端部を強固にシールし、上述のような切断補助線を外フィルム部１０又は第一内フィルム部２０におけるシール部分近傍に設けてもよい。このようにしても、開封時に外フィルム部１０に対して第一内フィルム部２０が切断補助線で分断（分離）させることができるので、上記実施形態と同様の効果を奏することができる。但し、このようにすると、フィルムに対するシールやフィルムに対する切断補助線の加工等によって製造コストが高騰する傾向にあるため、外フィルム部１０と第一フィルム部２０，２０とを所定幅で剥離可能にシールするようにしたり、上述のように一枚のフィルムを曲げ加工して外フィルム部１０、第一内フィルム部２０，２０及び第二内フィルム部３０，３０を形成し、外フィルム部１０と第一内フィルム部２０，２０との境界に切断補助線（例えば、ミシン目やハーフカット等）を設けたりすることが好ましい。さらに、開封の容易性（外フィルム部１０に対する第一内フィルム部２０の分離性）を考慮すれば、外フィルム部１０の側端部と第一フィルム部２０，２０の基端部とを所定幅で剥離可能にシールすることがより好ましい。   Further, the base end portion of the first inner film portion 20 is firmly sealed to the side end portion of the outer film portion 10, and the cutting auxiliary line as described above is provided near the seal portion in the outer film portion 10 or the first inner film portion 20. May be provided. Even if it does in this way, since the 1st inner film part 20 can be parted (separated) with an auxiliary cutting line with respect to the outer film part 10 at the time of opening, there can exist an effect similar to the said embodiment. However, in this case, since the manufacturing cost tends to increase due to the sealing of the film and the processing of the auxiliary cutting line for the film, the outer film portion 10 and the first film portions 20 and 20 can be peeled with a predetermined width. The outer film part 10, the first inner film part 20, 20 and the second inner film part 30, 30 are formed by bending a single film as described above to form the outer film part 10, It is preferable to provide a cutting auxiliary line (for example, perforation or half cut) at the boundary between the first inner film portions 20 and 20. Further, considering the ease of opening (separability of the first inner film portion 20 with respect to the outer film portion 10), the side end portion of the outer film portion 10 and the base end portions of the first film portions 20 and 20 are predetermined.
