Description

本発明は、略円錐状の内容物を包装するための包装用シートに関する。 The present invention relates to a packaging sheet for packaging a substantially conical contents.

一般に花手巻きと呼ばれる、略円錐状に形成した手巻き寿司を包装するのに、例えば、特許文献１に示されるように、互いに周縁部で固定された外フィルムと内フィルムとの二枚のフィルムから構成される包装用シートであって、外フィルムと内フィルムとの間に海苔を収容する矩形状の包装用シートが用いられている。 In order to wrap hand-rolled sushi formed generally in a conical shape, commonly referred to as Hanamaki, for example, as shown in Patent Document 1, two sheets of an outer film and an inner film fixed at the periphery are mutually attached. A packaging sheet made of a film, which is a rectangular packaging sheet that accommodates seaweed between an outer film and an inner film, is used.

このような包装用シートで手巻き寿司を略円錐状に包装した場合（ここで略円錐状に包装するとは略円錐状の内容物の周面に沿って包装用シートを巻き付けることをいう。略円錐状に巻くというときも同様である。）、円錐の底面に相当する部分で飯が露出することとなる。このため、特許文献１では、露出する部分を包装後に覆うためのカバー部材を包装用シートに設け、略円錐状に成型した寿司を包装したあと、円錐の底面に対応する露出した部分を外側からカバー部材で覆うことが提案されている。 When hand-rolled sushi is wrapped in a substantially conical shape with such a packaging sheet (here, wrapping in a substantially conical shape means winding the packaging sheet along the peripheral surface of the substantially conical content. The same applies when winding in a cone .) Rice is exposed at the portion corresponding to the bottom of the cone. For this reason, in Patent Document 1, a cover member for covering the exposed portion after packaging is provided on the packaging sheet, and after packaging the sushi molded into a substantially conical shape, the exposed portion corresponding to the bottom surface of the cone is externally provided. It has been proposed to cover with a cover member.

また、特許文献２，３には、包装用シートに略円錐状に成型した寿司を設置した後、予めカバー部材で寿司における円錐の底面に相当する部分を覆ってから寿司を包装することが提案されている。 Patent Documents 2 and 3 propose that a sushi molded in a substantially conical shape is placed on a packaging sheet, and then a portion corresponding to the bottom of the cone in the sushi is covered with a cover member in advance before packaging the sushi. Has been.

国際公開第２０１１／０２４５２６号International Publication No. 2011/024526 実開昭６１−１８０９６８号公報Japanese Utility Model Publication No. 61-180968 実公平３−２４０６７号公報Japanese Utility Model Publication 3-24067

包装後に露出する部分を覆うことの目的は、包装用シート内を密閉状態にして外部からの埃や虫などの混入を防ぐことや飯の乾燥を防ぐことにあるところ、特許文献１のように包装後にカバー部材で外側から露出する部分（円錐の底面に対応する部分）を覆って包装用シート内を密閉状態にする場合、カバー部材と包装用シートとの間を塞ぐのにシール等の固定手段を用いる必要があるが、固定手段を用いてカバー部材と包装用シートとの間に隙間が生じないようにするには手間と時間を要するものであった。 The purpose of covering the exposed portion after packaging is to seal the inside of the packaging sheet to prevent the entry of dust, insects, etc. from the outside, and to prevent the drying of rice. Covering the portion exposed from the outside with the cover member after packaging (the portion corresponding to the bottom of the cone) and sealing the inside of the packaging sheet, fixing a seal or the like to close the space between the cover member and the packaging sheet Although it is necessary to use the means, it takes time and effort to use the fixing means to prevent a gap between the cover member and the packaging sheet.

そして、たとえ手間暇かけてカバー部材と包装用シートとの間を塞いだとしても、カバー部材で露出する部分を包装用シートの外側から覆うという手段では、カバー部材と飯との間に余分な空間が生じるためにカバー部材が変形等を起こし、これに伴ってどこかしらに隙間が生じる虞があるとともにその見栄えも悪くなる問題があった。 And even if the cover member and the packaging sheet are closed by taking time and effort, the means for covering the portion exposed by the cover member from the outside of the packaging sheet is an extra space between the cover member and the rice. Since the space is generated, the cover member is deformed, and there is a problem that a gap may be generated somewhere and the appearance of the cover member may be deteriorated.

また、特許文献２，３のように、予めカバー部材で外側から露出する部分（円錐の底面に対応する部分）を覆ってから包装する方法では、特許文献２の方法は目印等を用いて飯を覆うとともに包装を行っていることから明らかなように、隙間なく飯を覆い且つ包装後の見栄えもよくするためには正確な包装作業が要求され、また、隙間なく飯を覆った後はその状態を保ちながら包装作業を行わなければならず、特許文献１と同様に、カバー部材で飯を覆うのに手間と時間を要するものであった。 Further, as in Patent Documents 2 and 3, in the method of packaging after covering the part exposed from the outside with the cover member in advance (the part corresponding to the bottom surface of the cone), the method of Patent Document 2 uses a mark or the like. As is clear from the fact that it covers and wraps the rice, it is necessary to accurately wrap the rice to cover it without gaps and improve its appearance after packaging. The packaging operation must be performed while maintaining the state, and it takes time and effort to cover the rice with the cover member, as in Patent Document 1.

また、特許文献３の方法は円錐状に巻いた包装用シートの円錐の底辺や内周面の全周に対しカバー部材が隙間なく接着されているわけではないので、カバー部材と包装用シートとの間にある程度の隙間が生じることは避けられないものであった。 Further, the method of Patent Document 3 is not such that the cover member is bonded to the entire bottom of the cone or the entire circumference of the cone of the packaging sheet wound in a conical shape, so that the cover member and the packaging sheet It was inevitable that a certain amount of gap was generated between the two.

つまり、上記特許文献１〜３の包装用シートでは、包装用シート内を密閉しようとするのに手間と時間がかかり容易ではなく、また、カバー部材と包装用シートとの間に隙間が生じ易く、包装用シート内の密閉度が不十分で埃や虫などの混入や飯の乾燥を確実に防ぐには不十分であるという問題があった。 That is, in the packaging sheets of Patent Documents 1 to 3, it is not easy and time-consuming to try to seal the inside of the packaging sheet, and a gap is easily generated between the cover member and the packaging sheet. However, there is a problem that the degree of sealing in the packaging sheet is insufficient and it is insufficient to reliably prevent dust and insects from being mixed and drying of rice.

この実情に鑑み、本発明の主たる課題は、埃や虫などの混入や飯の乾燥を容易に且つ確実に防ぐため、包装用シート内の密閉度を高めた包装用シートを提供することにある。 In view of this situation, the main problem of the present invention is to provide a packaging sheet having a high degree of sealing within the packaging sheet in order to easily and reliably prevent dust and insects from mixing and drying of rice. .

本発明に係る包装用シートの特徴は、
略円錐状の内容物を包装するための包装用シートであって、
略正方形状であり、包装時に前記内容物を対角線に沿って設置し、前記内容物の頂部が向く側の隣り合う２つの頂部側辺部を突き合わせる状態で前記内容物の周面に沿わせて前記内容物に巻き付ける設置部と、
前記設置部における前記頂部側辺部以外の２辺を結合部として前記設置部と結合した略正方形状の蓋用シートと、
前記設置部における前記頂部側辺部のいずれか一方から延び、包装時に前記設置部を前記内容物の周面に沿わせて巻き付けたときにさらに前記設置部の外側面に巻き付ける巻き付け部と、を備え、
前記蓋用シートと前記設置部とで、前記内容物を収容することで前記蓋用シートで前記内容物が蓋されるポケット部を形成する構成にしてある点にある。 The characteristics of the packaging sheet according to the present invention are as follows:
A packaging sheet for packaging a substantially conical contents,
A substantially square shape, the contents were placed along the diagonals during packaging, along a peripheral surface of the content in a state of butting the two top side portion adjacent the side where the top faces of the contents An installation section that wraps around the contents ,
A substantially square lid sheet coupled to the installation portion with two sides other than the top side portion in the installation portion as a coupling portion ;
A winding portion that extends from any one of the top side portions of the installation portion and winds around the outer surface of the installation portion when the installation portion is wound along the peripheral surface of the contents during packaging. Prepared,
The lid sheet and the installation portion are configured to form a pocket portion where the contents are covered with the lid sheet by accommodating the contents.

つまり、包装用シートに上記のようなポケット部を設けることにより、このポケット部に内容物を収容した状態で包装用シートを略円錐状に巻いて内容物を包装すれば、包装後に従来露出されることとなっていた部分を蓋用シートによって（つまり、ポケット部の底部によって）蓋することができる。そして、ポケット部のうち内容物を収容するための開口部については、包装用シートを略円錐状に巻く際に包装用シートの内側面により塞がれることとなる。これにより、内容物を包装用シートによって確実に密閉状態にすることができる。 In other words, by providing the pocket portion as described above in the packaging sheet, if the packaging sheet is wrapped in a substantially conical shape while the contents are accommodated in the pocket portion, the contents are conventionally exposed after packaging. The part to be covered can be covered with a cover sheet (that is, with the bottom of the pocket part). And about the opening part for accommodating the content among pocket parts, when winding a packaging sheet in substantially cone shape, it will be obstruct | occluded by the inner surface of the packaging sheet. Thereby, the contents can be reliably sealed by the packaging sheet.

即ち、ポケット部に内容物を収容した状態で包装用シートを略円錐状に巻いて内容物を包装することにより、単にポケット部に内容物を収容するという動作のみで、上記従来の包装用シートのように包装用シート内を密閉しようとするのに手間と時間を要することなく、容易且つ確実に包装用シート内を密閉状態とすることができる。 That is, the conventional packaging sheet can be obtained simply by storing the contents in the pocket portion by wrapping the packaging sheet in a substantially conical shape while the contents are accommodated in the pocket portion. Thus, the inside of the packaging sheet can be easily and reliably sealed without requiring time and effort to seal the inside of the packaging sheet.

また、包装用シートを略円錐状に巻いて内容物を包装したときに、略円錐状の包装用シートの底辺となる設置部の周縁（包装時に前記設置部の対角線に沿って前記設置部に前記内容物を設置するときに、前記内容物の底面が向く側の隣り合う２辺）を結合部として蓋用シートが設置部と結合しているため、円錐状に巻いた包装用シートの円錐の底辺（内容物を包装したときに略円錐状の内容物における底面周縁に沿う辺を意味する）の全周に対し蓋用シートが隙間なく結合されている状態となる。また、ポケット部に内容物を収容するに伴って、蓋用シートと内容物との間に余分な空間を生じさせず、包装後に蓋用シートが内容物に隙間なく接触した状態を現出することができる。これにより、カバー部材と包装用シートとの間に隙間が生じやすかった上記従来の包装用シートに比べ、包装用シート内の密閉度を極めて高い状態とすることができる。 In addition, when the packaging sheet is wrapped in a substantially conical shape and the contents are packaged, the peripheral edge of the installation portion that becomes the bottom of the substantially conical packaging sheet (at the installation portion along the diagonal line of the installation portion during packaging) When the contents are installed, the lid sheet is coupled to the installation section using the two adjacent sides facing the bottom of the contents as the coupling portion, so the cone of the packaging sheet wound in a conical shape The cover sheet is in a state of being joined to the entire circumference of the bottom side (meaning the side along the bottom edge of the substantially conical content when the content is packaged) without any gap. In addition, as the contents are stored in the pocket portion, no extra space is created between the lid sheet and the contents, and the lid sheet comes into contact with the contents without any gaps after packaging. be able to. Thereby, the sealing degree in a packaging sheet can be made into a very high state compared with the said conventional packaging sheet in which the clearance gap was easy to produce between a cover member and a packaging sheet.

さらに、包装後に蓋用シートが内容物に隙間なく接触した状態となるため、包装後の状態においてスッキリした印象を与え、また、蓋用シートが内容物に隙間なく接触しているので内容物の表面をきれいに目視できる状態にでき、意匠的にも優れた包装用シートとすることができる。 Furthermore, since the lid sheet is in contact with the contents without any gaps after packaging, it gives a clean impression after the packaging, and since the lid sheet is in contact with the contents without gaps, The surface can be clearly seen, and a packaging sheet excellent in design can be obtained.

本発明に係る包装用シートにおいて、前記設置部とする内側半面と、折り返し辺において折り返して前記内側半面に接着し前記蓋用シートとする外側半面と、を備える折り返しシートを有し、前記外側半面を前記折り返し辺において折り返し、前記内側半面の周縁のうち、前記折り返し辺を前記結合部の１辺とするときの残りの１辺において前記外側半面の周縁を前記内側半面に接合することにより、前記内側半面と前記外側半面とで前記ポケット部を形成してあると好適である。 The packaging sheet according to the present invention has a folded sheet comprising an inner half surface serving as the installation portion, and an outer half surface folded at a folded side and bonded to the inner half surface to serve as the lid sheet. The outer half surface is joined to the inner half surface in the remaining one side when the folded side is one side of the coupling portion among the peripheral edges of the inner half surface. It is preferable that the pocket portion is formed by the inner half surface and the outer half surface.

この構成によれば、本発明に係るポケット部を一体形成した包装用シートを一から開発・製造することなく、従来品である包装用シートを利用して、従来品に対して上記構成における折り返し用シートを用いることにより、容易に本発明の特徴であるポケット部を形成することができる。 According to this configuration, the packaging sheet integrally formed with the pocket portion according to the present invention is not developed and manufactured from scratch, and the conventional packaging sheet is used to fold back the conventional configuration in the above configuration. By using the sheet for use, the pocket portion that is a feature of the present invention can be easily formed.

また、上記構成に代えて、前記設置部における前記結合部とする２辺に前記設置部と略同型の前記蓋用シートの周縁を接着することにより前記ポケット部を形成しても好適である。 In addition, instead of the above configuration, it is preferable that the pocket portion is formed by adhering the periphery of the lid sheet substantially the same type as the installation portion to the two sides serving as the coupling portion in the installation portion.

この構成によれば、本発明に係るポケット部を一体形成した包装用シートを一から開発・製造することなく、従来品である包装用シートを利用して、従来品における設置部に対して追加的に蓋用シートを接着して、容易に本発明の特徴であるポケット部を形成することができる。 According to this configuration, the packaging sheet integrally formed with the pocket portion according to the present invention is added to the installation part in the conventional product by using the packaging sheet which is the conventional product without developing and manufacturing from scratch. In addition, the pocket sheet, which is a feature of the present invention, can be easily formed by bonding the lid sheet.

また、本発明に係る包装用シートにおいて、２つの前記頂部側辺部のうち前記巻き付け部が延びていない前記頂部側辺部に、折り返して内容物を覆うシート片を設けてもよい。 Moreover, the sheet | seat for packaging which concerns on this invention WHEREIN : You may provide the sheet | seat piece which folds and covers the content in the said top part side part in which the said winding part does not extend among two said top part side parts .

包装用シートを略円錐状に巻いて内容物を包装する場合に、略円錐状の包装用シートの頂部において隙間が生じる虞があり、これにより、包装用シート内の密閉度が不十分となる虞があるが、上記構成によれば、シート片を折り返してシート片により内容物を覆った状態で包装用シートを略円錐状に巻いて内容物を包装することにより、シート片により内容物における円錐の頂部に対応する部分が蓋されるから、より確実に内容物を包装用シートによって密閉状態にすることができる。 When a packaging sheet is wound in a substantially conical shape and the contents are packaged, there is a risk that a gap will be formed at the top of the substantially conical packaging sheet, which results in an insufficient degree of sealing in the packaging sheet. Although there is a possibility, according to the above configuration, by folding the sheet piece and covering the content with the sheet piece, the packaging sheet is wrapped in a substantially conical shape, and the content is wrapped with the sheet piece. Since the portion corresponding to the top of the cone is covered, the contents can be more securely sealed by the packaging sheet.

図１，２は、略円錐状の寿司やおにぎり等の飯を包装する包装用シート１の説明斜視図であり、海苔６を収容するための海苔収容シート２と寿司飯や米飯等を収容するための米飯収容シート３（折り返しシートに相当）とで構成される。 1 and 2 are explanatory perspective views of a packaging sheet 1 for packaging rice such as substantially conical sushi and rice balls, which accommodates a laver containing sheet 2 for containing laver 6 and sushi rice, cooked rice, and the like. And the cooked rice containing sheet 3 (corresponding to a folded sheet).

図１（ａ）に示すように、海苔収容シート２は、飯の包装後に外側に位置する矩形の外フィルム４と、飯の包装後に内側に位置する２枚の内フィルム（図１（ａ）中左側に位置し略正方形の第１内フィルム５ａと図中右側に位置する矩形の第２内フィルム５ｂ）とから構成される。 As shown in FIG. 1 (a), the laver-containing sheet 2 includes a rectangular outer film 4 positioned outside after the packaging of the rice and two inner films positioned inside after the packaging of the rice (FIG. 1 (a)). The first inner film 5a having a substantially square shape located on the left side in the middle and the second inner film 5b having a rectangular shape located on the right side in the figure.

外フィルム４の２つの長辺の中央付近にはそれぞれ２つの切込み７ａ，７ｂ（図１（ａ）中左側が切込み７ａ、右側が切込み７ｂ）を形成してある。詳しくは後述するが、外フィルム４の４つの切込み７ａ，７ｂ，７ｂ，７ａで囲まれる部分（図１（ａ）中の点線の領域）をシート開封部７として、包装後にこのシート開封部７を切り取ることで包装用シート１の開封を行う。また、このシート開封部７における切込み７ｂ，７ｂ側の周縁には、外フィルムの短辺方向の全長にわたって、外フィルム４における海苔６を載置する側に、切り取り作業を案内するためのカットテープ８を熱融着により接着してある。 Two cuts 7a and 7b (the cut 7a on the left side and the cut 7b on the right side in FIG. 1A) are formed near the center of the two long sides of the outer film 4, respectively. As will be described in detail later, a portion surrounded by the four cuts 7a, 7b, 7b, 7a of the outer film 4 (a dotted line region in FIG. 1A) is used as a sheet opening portion 7, and this sheet opening portion 7 after packaging. The packaging sheet 1 is opened by cutting the sheet. Further, a cut tape for guiding the cutting operation to the side on which the laver 6 in the outer film 4 is placed over the entire length in the short side direction of the outer film at the periphery of the cuts 7b and 7b in the sheet opening portion 7 8 is bonded by heat fusion.

外フィルム４と第１内フィルム５ａと第２内フィルム５ｂとは海苔６を収容した状態で外周縁部の所定位置で熱融着することにより接着してある（図１（ａ）中の外周縁部の斜線部分が熱融着部分９である）。より詳しくは、外フィルム４の切込み７ａ，７ｂの間（つまりシート開封部７）を除く外周縁部については、その全周について第１内フィルム５ａ及び第２内フィルム５ｂの外周縁部と接着し、外フィルム４の切込み７ａ，７ｂの間（つまりシート開封部７）については中央付近の一点においてのみ第１内フィルム５ａの外周縁部と接着してある。 The outer film 4, the first inner film 5 a, and the second inner film 5 b are bonded together by heat-sealing at a predetermined position on the outer peripheral edge with the laver 6 accommodated (outside in FIG. 1 (a)). The hatched portion of the peripheral portion is the heat fusion portion 9). More specifically, with respect to the outer peripheral edge excluding the space between the cuts 7a and 7b of the outer film 4 (that is, the sheet unsealing part 7), the outer periphery is bonded to the outer peripheral edges of the first inner film 5a and the second inner film 5b. In addition, between the cuts 7a and 7b of the outer film 4 (that is, the sheet opening portion 7) is bonded to the outer peripheral edge portion of the first inner film 5a only at one point near the center.

外フィルム４の長辺方向における第１内フィルム５ａの長さは、外フィルム４の長辺における切込み７ａ側の一端から切込み７ｂまでの長さと略同一にし、第２内フィルム５ｂの外フィルム４の長辺方向の長さは、外フィルム４の長辺における切込み７ｂ側の他端からカットテープ８を覆う程度の長さとし、図１（ｂ）に示すように、第１内フィルム５ａと第２内フィルム５ｂとの一部が重なるようにしてある。これにより、海苔６が表面に露出することなく収容されて、内容物たる寿司１４を海苔収容シート２に載置して包装しても寿司１４と海苔６とが直接触れることがない。 The length of the first inner film 5a in the long side direction of the outer film 4 is substantially the same as the length from one end on the cut 7a side to the cut 7b on the long side of the outer film 4, and the outer film 4 of the second inner film 5b. The length in the long side direction of the outer film 4 is such a length that covers the cut tape 8 from the other end on the side of the cut 7b in the long side of the outer film 4, and as shown in FIG. A part of the inner 2 film 5b overlaps. Thereby, even if the nori 6 is accommodated without being exposed on the surface, the sushi 14 and the nori 6 are not directly touched even if the content sushi 14 is placed on the nori accommodation sheet 2 and packaged.

また、第１内フィルム５ａと第２内フィルム５ｂとは直接つながっていないため、図４（ｃ）に示すように、シート開封部７を切り離すことにより、海苔収容シート２は、第１内フィルム５ａを有する第１部分２ａと、第２内フィルム５ｂを有する第２部分２ｂとに分離される。 Moreover, since the 1st inner film 5a and the 2nd inner film 5b are not connected directly, as shown in FIG.4 (c), the nori accommodation sheet | seat 2 is separated into the 1st inner film by separating the sheet | seat opening part 7. As shown in FIG. The first portion 2a having 5a and the second portion 2b having second inner film 5b are separated.

図２（ａ）に示すように、米飯収容シート３は長辺と短辺の比率がおよそ２：１の矩形であり、その半面（内側半面）３ａを第１内フィルム５ａに重ねて、他の半面（外側半面）３ｂが外フィルム４における長辺の外側からはみ出す状態で配置してある。 As shown in FIG. 2 (a), the cooked rice containing sheet 3 is a rectangle having a ratio of the long side to the short side of about 2: 1, and its half surface (inner half surface) 3a is overlaid on the first inner film 5a. The half surface (outer half surface) 3b of the outer film 4 is arranged so as to protrude from the outer side of the long side.

そして、外フィルム４の長辺方向における第１内フィルム５ａの外周縁部のうちシート開封部７に対応する部分を除く外周縁部を熱融着部分１０として、この熱融着部分１０において米飯収容シート３における内側半面３ａを海苔収容シート２に熱融着により接着してある。 And the outer peripheral edge part except the part corresponding to the sheet | seat opening part 7 among the outer peripheral edge parts of the 1st inner film 5a in the long side direction of the outer film 4 is made into the heat sealing | fusion part 10, and in this heat sealing | fusion part 10, the cooked rice The inner half surface 3a of the accommodation sheet 3 is bonded to the seaweed accommodation sheet 2 by heat fusion.

そして、図２（ｂ）に示すように、外フィルム４からはみ出した状態の外側半面３ｂを、内側半面３ａと外側半面３ｂとが重なるように折り返し辺部１２において折り返し、第１内フィルム５ａにおける外フィルム４の短辺に対応する外周縁部とこの外周縁部に対応する内側半面３ａと外側半面３ｂとの両方の外周縁部とを熱融着部分１１として熱融着して、米飯収容シート３と外フィルム４とを接着してある。なお、この場合、折り返し辺部１２は、内側半面３ａと外側半面３ｂとが折り返し辺部１２を対称軸として線対称な形状となる位置に設定してある。 And as shown in FIG.2 (b), the outer side half surface 3b of the state which protruded from the outer film 4 is folded in the folding | turning edge part 12 so that the inner side half surface 3a and the outer side half surface 3b may overlap, and in the 1st inner film 5a The outer peripheral edge portion corresponding to the short side of the outer film 4 and the outer peripheral edge portions of both the inner half surface 3a and the outer half surface 3b corresponding to the outer peripheral edge portion are heat-sealed as the heat-welding portion 11 to accommodate the cooked rice The sheet 3 and the outer film 4 are bonded. In this case, the folded side portion 12 is set at a position where the inner half surface 3a and the outer half surface 3b have a line-symmetric shape with the folded side portion 12 as an axis of symmetry.

このようにして海苔収容シート２に米飯収容シート３を接着することにより、米飯収容シート３は、内側半面３ａ（設置部に相当）と外側半面３ｂ（蓋用シートに相当）とで、略正方形状に折りたたんだ米飯収容シート３における熱融着部分１１と折り返し辺部１２に対応する２辺（結合部に相当）を閉部１３ａとし他の２辺（頂部側辺部に相当）を開部１３ｂとするポケット部１３を形成する。 By bonding the cooked rice containing sheet 3 to the laver containing sheet 2 in this way, the cooked rice containing sheet 3 has an inner half surface 3a (corresponding to the installation portion) and an outer half surface 3b (corresponding to the lid sheet), which is substantially square. The two sides (corresponding to the connecting portion) corresponding to the heat-sealed portion 11 and the folded-back side portion 12 of the cooked rice containing sheet 3 folded in a shape are the closed portion 13a and the other two sides (corresponding to the top side portion) are the open portions A pocket portion 13 is formed as 13b.

この場合、熱融着部分１１と折り返し辺部１２に対応する２辺は、図３（ａ）〜（ｄ）で示すようにして包装用シート１を略円錐状に巻いて寿司１４を包装したときに、略円錐状の包装用シート１の底辺となるようにしてある。なお、図示は省略するが、外側半面３ｂが外フィルム４の短辺の外側からはみ出す状態にして、図２（ｂ）における熱融着部分１１に相当する部分が折り返し辺部となるとともに、図２（ｂ）における折り返し辺部１２に相当する部分が熱融着部分となる状態でポケット部１３を形成してもよい。 In this case, the two sides corresponding to the heat fusion part 11 and the folded side part 12 wrapped the sushi 14 by winding the packaging sheet 1 in a substantially conical shape as shown in FIGS. Sometimes, it becomes the bottom of the substantially conical packaging sheet 1. Although illustration is omitted, the outer half surface 3b protrudes from the outer side of the short side of the outer film 4, and the portion corresponding to the heat fusion portion 11 in FIG. The pocket portion 13 may be formed in a state where the portion corresponding to the folded side portion 12 in 2 (b) is a heat-sealed portion.

上記のようにして包装用シート１は構成される。次に、包装用シート１を用いた略円錐状の寿司１４の包装について説明する。 The packaging sheet 1 is configured as described above. Next, the packaging of the substantially conical sushi 14 using the packaging sheet 1 will be described.

まず、図３（ａ）に示すように、寿司１４は具材１４ａを詰めて略円錐状に成型してある。そして、この寿司１４における略円錐状の底面１４ｂがポケット部１３の閉部１３ａの側を向く状態（寿司１４における略円錐状の頂部１４ｃがポケット部１３の開部１３ｂを向く状態）で、寿司１４をポケット部１３内に収容する。 First, as shown in FIG. 3A, the sushi 14 is filled with ingredients 14a and formed into a substantially conical shape. Then, in a state where the substantially conical bottom surface 14b of the sushi 14 faces the closed portion 13a side of the pocket portion 13 (a state where the substantially conical top portion 14c of the sushi 14 faces the open portion 13b of the pocket portion 13), the sushi 14 is accommodated in the pocket portion 13.

次に、図３（ｂ）に示すように、ポケット部１３における閉部１３ａの一端１５ａから閉部１３ａの他端１５ｂに向かって包装用シート１を折り返すようにして、寿司１４における略円錐状の周面１４ｄに沿わせながら、包装用シート１の一方側１ａを寿司１４に対し巻き付ける。続けて、図３（ｃ）に示すように、包装用シート１の他方側１ｂの一端１５ｃから包装用シート１を折り返すようにして、寿司１４における略円錐状の周面１４ｄに沿わせながら、包略正方形状に折りたたんだ米飯収容シート３の対角線１６上にカットテープ８が位置するように、装用シート１の他方側１ｂを寿司１４に対し巻き付ける。 Next, as shown in FIG. 3 (b), the packaging sheet 1 is folded back from the one end 15a of the closed portion 13a to the other end 15b of the closed portion 13a in the pocket portion 13, so that the substantially conical shape in the sushi 14 is obtained. The one side 1a of the packaging sheet 1 is wound around the sushi 14 along the peripheral surface 14d. Subsequently, as shown in FIG. 3 (c), the wrapping sheet 1 is folded from one end 15c on the other side 1b of the wrapping sheet 1, and along the substantially conical circumferential surface 14d of the sushi 14, The other side 1b of the wearing sheet 1 is wound around the sushi 14 so that the cut tape 8 is positioned on the diagonal line 16 of the cooked rice containing sheet 3 folded in a substantially square shape.

最後に、図３（ｃ）における包装用シート１の残余部分１７（巻き付け部に相当）を寿司１４に対しさらに巻き付けていき、図３（ｄ）に示すように、残余部分１７の端部１７ａがカットテープ８に重ならない状態で、固定用シール１８により残余部分１７の端部を包装用シート１に接着する。この際、固定用シール１８はシート開封部７を超えて包装用シート１と接着しているが、固定用シール１８がカットテープ８に重なった状態となっているため、後述するように、包装用シート１からシート開封部７を取り去るに伴い、カットテープ８により固定用シール１８が破れることとなり、固定用シール１８がシート開封部７の除去の弊害とはならない。 Finally, the remaining portion 17 (corresponding to the winding portion ) of the packaging sheet 1 in FIG. 3 (c) is further wound around the sushi 14, and as shown in FIG. 3 (d), the end portion 17a of the remaining portion 17 The end of the remaining portion 17 is adhered to the packaging sheet 1 by the fixing seal 18 in a state where the sheet does not overlap the cut tape 8. At this time, the fixing seal 18 is bonded to the packaging sheet 1 beyond the sheet opening portion 7, but the fixing seal 18 is in a state of being overlapped with the cut tape 8. As the sheet opening portion 7 is removed from the sheet 1, the fixing seal 18 is broken by the cut tape 8, and the fixing seal 18 does not cause an adverse effect of removing the sheet opening portion 7.

上記のように、ポケット部１３に寿司１４を収容した状態で包装用シート１を略円錐状に巻いて寿司１４を包装すれば、図３（ｄ）のように、包装後に従来露出されることとなっていた寿司１４の底面１４ｂを米飯収容シート３の外側半面３ｂ（蓋用シートに相当）によって蓋した状態にすることができ、さらに、ポケット部１３の開部１３ｂについては、包装用シート１を略円錐状に巻く際に包装用シート１の内側面により塞がれることとなる。これにより、寿司１４を包んだ包装用シート１内が密閉状態となる。 As described above, if the sushi 14 is wrapped around the packaging sheet 1 in a state where the sushi 14 is accommodated in the pocket portion 13 to wrap the sushi 14, the sushi 14 is conventionally exposed after packaging as shown in FIG. The bottom surface 14b of the sushi 14 can be covered with the outer half surface 3b (corresponding to a lid sheet) of the cooked rice containing sheet 3, and the opening 13b of the pocket portion 13 has a packaging sheet. When 1 is wound in a substantially conical shape, it is blocked by the inner surface of the packaging sheet 1. Thereby, the inside of the packaging sheet 1 wrapping the sushi 14 is in a sealed state.

即ち、ポケット部１３に寿司１４を収容した状態で包装用シート１を略円錐状に巻いて寿司１４を包装することにより、容易且つ確実に包装用シート１内を密閉状態とすることができる。 That is, when the packaging sheet 1 is wound in a substantially conical shape and the sushi 14 is packaged while the sushi 14 is accommodated in the pocket portion 13, the inside of the packaging sheet 1 can be easily and reliably sealed.

また、包装用シート１を円錐状に巻いたときに円錐の底辺となる熱融着部分１１と折り返し辺部１２に対応する２辺が塞がれた状態となっているため、円錐状に巻いた包装用シート１の円錐の底辺の全周に対し外側半面３ｂが隙間なく結合されている状態となり、そして、ポケット部１３に寿司１４を収容するに伴って、図３（ｄ）のように、包装後に米飯収容シート３の外側半面３ｂと寿司１４との間に余分な空間が生じることなく、外側半面３ｂが寿司１４に隙間なく接触した状態を現出することができ、これにより、外側半面３ｂと寿司１４との間の空間に起因して米飯収容シート３の外側半面３ｂが変形して隙間が生じてしまうという問題を回避することができる。 Further, since the packaging sheet 1 is wound in a conical shape, the two sides corresponding to the heat-sealed portion 11 and the folded-back side portion 12 that are the bottom sides of the cone are closed, so that the conical shape is wound. As shown in FIG. 3 (d), the outer half surface 3 b is joined to the entire circumference of the bottom of the cone of the wrapping sheet 1 without gaps, and the sushi 14 is accommodated in the pocket portion 13. In addition, after packaging, the outer half surface 3b can be brought into contact with the sushi 14 without any gaps between the outer half surface 3b of the cooked rice containing sheet 3 and the sushi 14, so that the outer side can be revealed. Due to the space between the half surface 3 b and the sushi 14, the problem that the outer half surface 3 b of the cooked rice containing sheet 3 is deformed to cause a gap can be avoided.

さらに、包装後に米飯収容シート３の外側半面３ｂが寿司１４に隙間なく接触した状態となるため、包装後の状態においてスッキリした印象を与え、また、米飯収容シート３の外側半面３ｂが寿司１４に隙間なく接触しているので寿司１４の表面がきれいに目視できる状態にでき、意匠的にも優れた包装用シートとすることができる。 Furthermore, since the outer half surface 3b of the cooked rice containing sheet 3 is in contact with the sushi 14 after the packaging without any gaps, a refreshing impression is given in the state after packaging, and the outer half surface 3b of the cooked rice containing sheet 3 is applied to the sushi 14. Since they are in contact with no gap, the surface of the sushi 14 can be clearly seen, and a packaging sheet that is excellent in design can be obtained.

最後に、略円錐状の寿司１４を包装した包装用シート１の開封について説明する。 Finally, the opening of the packaging sheet 1 in which the substantially conical sushi 14 is packaged will be described.

まず、図４（ａ）に示すように、包装用シート１からシート開封部７を取り去るため、切込み７ａ，７ｂからシート開封部７を下方に引っ張る。なお、この際、カットテープ８により固定用シール１８が破れることとなり、固定用シール１８が邪魔になることなく包装用シート１からシート開封部７が取り去られる。そして、これに伴い、包装用シート１の残余部分１７が包装用シート１から剥がれ、続けて、図４（ｂ）に示すように、寿司１４に巻き付けた状態の包装用シート１を開いていく。 First, as shown to Fig.4 (a), in order to remove the sheet opening part 7 from the packaging sheet 1, the sheet opening part 7 is pulled down from the notches 7a and 7b. At this time, the fixing seal 18 is broken by the cut tape 8, and the sheet opening portion 7 is removed from the packaging sheet 1 without the fixing seal 18 interfering. Accordingly, the remaining portion 17 of the packaging sheet 1 is peeled off from the packaging sheet 1, and then the packaging sheet 1 wound around the sushi 14 is opened as shown in FIG. 4 (b). .

次に、図４（ｃ）に示すように、包装用シート１を開封した後、シート開封部７を取り去ることにより第１部分２ａと第２部分２ｂとに分離した海苔収容シート２の第２部分２ｂを取り去り、海苔６を露出させ、また、略正方形状に折りたたんだ米飯収容シート３における熱融着部分１１を剥がして寿司１４を露出させる。 Next, as shown in FIG.4 (c), after opening the packaging sheet 1, the 2nd of the laver containing sheet | seat 2 isolate | separated into the 1st part 2a and the 2nd part 2b by removing the sheet | seat opening part 7 is shown. The part 2b is removed, the seaweed 6 is exposed, and the sushi 14 is exposed by peeling off the heat-sealed part 11 of the cooked rice-containing sheet 3 folded into a substantially square shape.

そして、図４（ｄ）に示すように、露出させた海苔６を寿司１４における略円錐状の周面１４ｄに沿わせて、海苔収容シート２の第１部分２ａから海苔６を引き抜きながら海苔６を寿司１４に巻き付けて、花手巻きの手巻き寿司１９を完成させる。 Then, as shown in FIG. 4 (d), the exposed laver 6 is placed along the substantially conical circumferential surface 14 d of the sushi 14, and the laver 6 is pulled out from the first portion 2 a of the laver containing sheet 2. Is wrapped around sushi 14 to complete hand-rolled sushi 19 of Hanatemaki.
