意匠登録第１２０３５４０号公報Design Registration No. 1203540 Gazette 意匠登録第１２０４０１１号公報Design Registration No. 1204011 Gazette

特許文献１や特許文献２などに記載されたおにぎり用外包フィルムの開封補助テープは細いものである。同文献には幅寸法は明記されていないが、このような外包フィルムの開封補助テープの幅は通常は１０ｍｍ以下である。また、フィルム本体や開封補助テープの厚さ寸法も明記されていないが、このような外包フィルムの場合、厚さは２０μｍ以下である。このような従来の外包フィルムでおにぎりを包装した場合、外包フィルムは薄い膜としておにぎりを包み、包装体としてはおにぎり自体の形状のままである。おにぎり用外包フィルム自体には構造材としての強度はない。特許文献１や特許文献２の使用状態を示す参考図に示されるように、包装されたおにぎりは広い面を水平にした状態で置かれることになる。 The opening auxiliary tape of the outer capsule film for rice balls described in Patent Document 1 and Patent Document 2 is thin. Although the width dimension is not specified in the document, the width of the opening auxiliary tape of such an outer film is usually 10 mm or less. Further, although the thickness dimensions of the film body and the opening auxiliary tape are not specified, the thickness of such an outer film is 20 μm or less. When the rice ball is wrapped with such a conventional outer packaging film, the outer packaging film wraps the rice ball as a thin film, and the package remains in the shape of the rice ball itself. The outer capsule film for rice balls itself does not have the strength as a structural material. As shown in the reference drawings showing the usage states of Patent Document 1 and Patent Document 2, the packaged rice balls are placed with a wide surface horizontal.

しかし、包装握り飯は店頭においては広い面を垂直にした状態で陳列されることが好ましい。その方が多数を狭い場所に並べることができ、また広い面に記載された商品名や説明を消費者が見ることができる。従来の包装部材は握り飯を立てた状態で支持するような強度を有しないため、そのような陳列は行いにくい。この発明は、握り飯を立った状態で支持しやすく、しかも簡単に広い開口を得ることができる握り飯用包装材および握り飯用包装材原反を提供することを目的とする。 However, it is preferable that the packaged rice balls are displayed in a store with the wide surface vertical. That way, many can be arranged in a narrow space, and consumers can see the product names and descriptions written on the wide surface. Since conventional packaging members do not have the strength to support rice balls in an upright position, such display is difficult. It is an object of the present invention to provide a rice ball wrapping material and a rice ball wrapping material raw fabric which can easily support a rice ball in a standing position and can easily obtain a wide opening.

上述の課題を解決するため、この発明の握り飯用包装材は、プラスチックフィルムを素材とする長方形状の包装シートと、包装シートに設けられた開封補助テープと、開封補助テープに沿ったいずれかの位置で包装シートに形成された切込み線と、切込み線を覆うカバーシートを有し、包装シートと開封補助テープの厚さが２０μｍ以上であり、開封補助テープの幅が２０ｍｍ以上かつ包装対象の握り飯の幅の８０％以下である。 In order to solve the above-mentioned problems, the wrapping material for rice balls of the present invention is either a rectangular wrapping sheet made of a plastic film, an opening auxiliary tape provided on the wrapping sheet, or an opening auxiliary tape. It has a notch line formed on the wrapping sheet at the position and a cover sheet that covers the notch line, the thickness of the wrapping sheet and the opening auxiliary tape is 20 μm or more, the width of the opening auxiliary tape is 20 mm or more, and the rice ball to be packaged. It is 80% or less of the width of.

また、この発明の握り飯用包装材原反は、連続した帯状のプラスチックフィルムを素材とする包装シートと、包装シートの長さ方向に沿って設けられた開封補助テープと、開封補助テープに沿って所定の周期で包装シートに形成された切込み線と、切込み線を覆うカバーシートを有し、包装シートと開封補助テープの厚さが２０μｍ以上であり、開封補助テープの幅が２０ｍｍ以上かつ包装対象の握り飯の幅の８０％以下である。 Further, the original wrapping material for rice balls of the present invention includes a wrapping sheet made of a continuous strip-shaped plastic film, an opening assist tape provided along the length direction of the wrapping sheet, and an opening assist tape. It has a notch line formed on the packaging sheet at a predetermined cycle and a cover sheet covering the notch line, the thickness of the packaging sheet and the opening auxiliary tape is 20 μm or more, the width of the opening auxiliary tape is 20 mm or more, and the object to be packaged. It is 80% or less of the width of rice balls.

さらに、開封補助テープの幅が包装対象の握り飯の幅の４０％以上８０％以下であり、開封補助テープの幅中心が包装シート幅中心とずれた位置に設けることもできる。 Further, the width of the opening auxiliary tape is 40% or more and 80% or less of the width of the rice ball to be packaged, and the center of the width of the opening auxiliary tape may be provided at a position deviated from the center of the width of the packaging sheet.

この発明において、厚くて幅広い開封補助テープが包装された握り飯を支え、握り飯を立った状態で支持することができる。 In the present invention, a thick and wide opening auxiliary tape can support the packaged rice balls, and the rice balls can be supported in a standing position.

この発明を実施するための形態について図面に基づいて説明する。まず、第１の実施形態について説明する。図１は握り飯用包装材原反の第１の例を示す斜視図である。プラスチックフィルムを素材とする長方形状の包装シート２は一定の幅の連続シートである。この包装シート２上には、その長さ方向に沿って開封補助テープ３が設けられている。そして、開封補助テープ３に沿って所定の周期Ｌで包装シート２と開封補助テープ３に切込み線４が形成されている。この周期Ｌが１枚の握り飯用包装材を構成する単位長さとなる。そして、切込み線４のある位置において、切込み線４を覆うカバーシート５が設けられている。 A mode for carrying out the present invention will be described with reference to the drawings. First, the first embodiment will be described. FIG. 1 is a perspective view showing a first example of a raw material for a packaging material for rice balls. The rectangular packaging sheet 2 made of a plastic film is a continuous sheet having a constant width. An opening auxiliary tape 3 is provided on the packaging sheet 2 along the length direction thereof. Then, a cut line 4 is formed in the packaging sheet 2 and the opening auxiliary tape 3 at a predetermined cycle L along the opening auxiliary tape 3. This cycle L is the unit length constituting one piece of rice ball packaging material. Then, at a position where the cut line 4 is located, a cover sheet 5 that covers the cut line 4 is provided.

このような開封補助テープはカットテープなどと呼ばれ、これを備えた食品包装材はすでに普及している。しかし、本発明においては、包装シート２は通常の握り飯用包装材よりも厚く、また開封補助テープ３は通常の握り飯用包装材より厚く幅広い。本例においては、包装シート２は厚さが４０μｍであり、開封補助テープ３は厚さが４０μｍで幅が２０ｍｍである。そして、開封補助テープ３は包装シート２の幅中央に沿って設けられている。また、包装シート２の幅は２００ｍｍ、繰返し周期は２２０ｍｍである。これは、幅８５ｍｍ程度で厚さ３０ｍｍ程度の円盤状の握り飯の包装用として選択した。 Such opening auxiliary tapes are called cut tapes, and food packaging materials equipped with them are already widespread. However, in the present invention, the packaging sheet 2 is thicker than the ordinary packaging material for rice balls, and the opening auxiliary tape 3 is thicker and wider than the ordinary packaging material for rice balls. In this example, the packaging sheet 2 has a thickness of 40 μm, and the opening auxiliary tape 3 has a thickness of 40 μm and a width of 20 mm. The opening auxiliary tape 3 is provided along the center of the width of the packaging sheet 2. The width of the packaging sheet 2 is 200 mm, and the repetition period is 220 mm. This was selected for packaging disc-shaped rice balls with a width of about 85 mm and a thickness of about 30 mm.

この握り飯用包装材原反１０は紙管１１に巻かれた状態で食品製造業者等に提供される。食品製造業者等はこの握り飯用包装材原反１０を使用して握り飯を包装し、包装握り飯を得る。紙管１１から引き出していき、先端にある部分に握り飯を載せ、所定の切断位置で一枚分の握り飯用包装材を切り出しながら、その握り飯用包装材で握り飯を包む。このとき、握り飯を立てたときに頂点となる位置に切込み線４を合わせる。そして、握り飯の裏側となる面に握り飯用包装材の折り畳み端が集まるように包み、その面に粘着テープやシールを貼って封止する。この包装作業は自動化された包装装置を用いて通常は実施される。 The raw rice ball packaging material 10 is provided to a food manufacturer or the like in a state of being wrapped around a paper tube 11. A food manufacturer or the like wraps rice balls using the raw rice ball packaging material 10 to obtain packaged rice balls. It is pulled out from the paper tube 11, the rice ball is placed on the tip portion, and one piece of the rice ball wrapping material is cut out at a predetermined cutting position, and the rice ball wrapping material is wrapped with the rice ball wrapping material. At this time, the cut line 4 is aligned with the position that becomes the apex when the rice ball is erected. Then, wrap the rice ball so that the folded ends of the rice ball packaging material gather on the back surface of the rice ball, and attach an adhesive tape or a seal to the surface to seal the rice ball. This packaging operation is usually performed using an automated packaging device.

図２は握り飯用包装材の第１の例を示す正面図であり、１周期分の握り飯用包装材原反１０を所定の切断位置で切り出した状態を示している。図３は同平面図、図４は同左側面図、図５は同右側面図、図６は同拡大Ａ－Ａ断面図である。なお、本例では握り飯用包装材はすべて透明な素材で構成されており、背面図は正面図と同一に表れ、底面図は平面図と対称に表れる。 FIG. 2 is a front view showing the first example of the rice ball packaging material, and shows a state in which the rice ball packaging material raw fabric 10 for one cycle is cut out at a predetermined cutting position. 3 is a plan view, FIG. 4 is a left side view, FIG. 5 is a right side view, and FIG. 6 is an enlarged AA sectional view. In this example, all the packaging materials for rice balls are made of a transparent material, the rear view appears in the same manner as the front view, and the bottom view appears symmetrically with the plan view.

得られた握り飯用包装材１はプラスチックフィルムを素材とする長方形状の包装シート２と、包装シート２に設けられた開封補助テープ３と、開封補助テープ３に沿ったいずれかの位置で包装シート２に形成された切込み線４と、切込み線４を覆うカバーシート５を有している。本例では幅２００ｍｍ、長さ２２０ｍｍであり、包装シート２は厚さが４０μｍ、開封補助テープ３は厚さが４０μｍで幅が２０ｍｍとなる。 The obtained packaging material 1 for rice balls is a rectangular packaging sheet 2 made of a plastic film, an opening assist tape 3 provided on the packaging sheet 2, and a packaging sheet at any position along the opening assist tape 3. It has a cut line 4 formed in 2 and a cover sheet 5 that covers the cut line 4. In this example, the width is 200 mm and the length is 220 mm, the packaging sheet 2 has a thickness of 40 μm, and the opening auxiliary tape 3 has a thickness of 40 μm and a width of 20 mm.

図７は包装握り飯の第１の例を示す斜視図であり、本例の握り飯用包装材原反１０および握り飯用包装材１の使用状態を示す。前述の包装方法によって握り飯ｘを本例の握り飯用包装材１で包装することによって図７のような包装握り飯２０が得られる。握り飯ｘは、円や楕円、あるいは三角形などの形状である広い面ｘ１を２面有する柱状である。包んでいる包装シート２は十分な厚みがあるので、握り飯用包装材自体が握り飯ｘを包んでいる状態でその形状を維持しようとするような構造体としての作用を有する。 FIG. 7 is a perspective view showing a first example of the packaged rice ball, and shows the usage state of the rice ball packaging material raw fabric 10 and the rice ball packaging material 1 of this example. By packaging the rice ball x with the rice ball packaging material 1 of this example by the above-mentioned packaging method, the packaged rice ball 20 as shown in FIG. 7 can be obtained. The rice ball x is a columnar shape having two wide faces x1 having a shape such as a circle, an ellipse, or a triangle. Since the wrapping sheet 2 has a sufficient thickness, the wrapping material for rice balls itself has an action as a structure that tries to maintain its shape while wrapping the rice balls x.

また、厚く幅広い開封補助テープ３も握り飯ｘを支持する構造材として機能する。握り飯ｘの下側に接する部分は支持台として、また、握り飯ｘの広い面ｘ１に沿った部分は支柱として作用し、握り飯ｘの広い面ｘ１が垂直に立つように支持することができる。 Further, the thick and wide opening auxiliary tape 3 also functions as a structural material for supporting the rice ball x. The portion in contact with the lower side of the rice ball x acts as a support base, and the portion along the wide surface x1 of the rice ball x acts as a support, so that the wide surface x1 of the rice ball x can be supported so as to stand vertically.

握り飯ｘの面ｘ１は広いので、大きなラベルを貼り、ブランドや商品説明、たとえば中の具材の説明などを効果的に示すことができる。本例では握り飯用包装材１は透明な部材で構成しているが、握り飯ｘの広い面ｘ１に当たる部分に印刷を施して、情報表示してもよい。この包装握り飯を店頭の陳列棚に立てた状態で置くことにより、広い面ｘ１に付した表示を消費者に見やすく提示することができる。また、このように立てて置くことにより、狭いスペースでも多くの商品を並べることができる。 Since the surface x1 of the rice ball x is wide, a large label can be attached to effectively indicate the brand and product description, for example, the description of the ingredients inside. In this example, the rice ball packaging material 1 is made of a transparent member, but information may be displayed by printing on the portion of the rice ball x that corresponds to the wide surface x1. By placing this packaged rice ball upright on the display shelf in the store, it is possible to present the display attached to the wide surface x1 to the consumer in an easy-to-see manner. In addition, by placing them upright in this way, many products can be lined up even in a narrow space.

この握り飯用包装材は頂部の切込み線４の部分をつまんで開封補助テープ３を引くことによって簡単に開封することができる。この発明の開封補助テープ３は幅が広いので、大きな開口を形成することができる。開封補助テープ３の幅を広くすることによってより大きな開口を得ることができるが、あまり広すぎると握り飯の広い面ｘ１に残る部分が少なくなり、持ちにくくなる。したがって、開封補助テープ３の幅は握り飯ｘの幅の８０％以下にすることが好ましい。 This rice ball packaging material can be easily opened by pinching the portion of the notch line 4 at the top and pulling the opening auxiliary tape 3. Since the opening auxiliary tape 3 of the present invention is wide, a large opening can be formed. A larger opening can be obtained by widening the width of the opening auxiliary tape 3, but if it is too wide, the portion remaining on the wide surface x1 of the rice ball becomes small and it becomes difficult to hold it. Therefore, the width of the opening auxiliary tape 3 is preferably 80% or less of the width of the rice ball x.

次に、この発明の第２の実施形態について説明する。図８は握り飯用包装材原反の第２の例を示す斜視図である。図９は握り飯用包装材の第２の例を示す正面図であり、図１０は同平面図、図１１は同左側面図、図１２は同右側面図、図１３は同拡大Ａ－Ａ断面図である。なお、本例でも握り飯用包装材１はすべて透明な素材で構成されており、背面図は正面図と対称に表れ、底面図は平面図と対称に表れる。 Next, a second embodiment of the present invention will be described. FIG. 8 is a perspective view showing a second example of the raw material of the packaging material for rice balls. 9 is a front view showing a second example of a packaging material for rice balls, FIG. 10 is a plan view, FIG. 11 is a left side view, FIG. 12 is a right side view, and FIG. 13 is an enlarged AA cross section. It is a figure. In this example as well, the packaging material 1 for rice balls is all made of a transparent material, and the rear view appears symmetrically with the front view and the bottom view appears symmetrically with the plan view.

この実施形態においても、第１の実施形態と同様に、握り飯用包装材１および握り飯用包装材原反１０は、包装シート２と、包装シート２に設けられた開封補助テープ３と、開封補助テープ３に沿ったいずれかの位置で包装シート２に形成された切込み線４と、切込み線を覆うカバーシート５を有する。包装シート２は厚く、また開封補助テープ３は厚く幅広い。包装シート２の厚さ、および開封補助テープ３の厚さと幅は第１の実施形態で示したものと同じにしている。 Also in this embodiment, as in the first embodiment, the rice ball packaging material 1 and the rice ball packaging material raw fabric 10 are the packaging sheet 2, the opening assist tape 3 provided on the packaging sheet 2, and the opening assist. It has a notch line 4 formed on the packaging sheet 2 at any position along the tape 3 and a cover sheet 5 covering the notch line. The packaging sheet 2 is thick, and the opening auxiliary tape 3 is thick and wide. The thickness of the packaging sheet 2 and the thickness and width of the opening auxiliary tape 3 are the same as those shown in the first embodiment.

第１の実施形態では開封補助テープ３は包装シート２の幅中央に沿って設けられているが、この実施形態では開封補助テープ３の幅中央は包装シート２の幅中央に対してずれた位置に設けられる。開封補助テープ３の一方の側辺は、包装時に握り飯の一側部に近い位置に設けられることが好ましい。本例ではより幅の広い開封補助テープ３が好ましく、包装対象の握り飯の幅の４０％以上８０％以下とすることができる。 In the first embodiment, the opening auxiliary tape 3 is provided along the center of the width of the packaging sheet 2, but in this embodiment, the center of the width of the opening auxiliary tape 3 is displaced from the center of the width of the packaging sheet 2. It is provided in. It is preferable that one side of the opening auxiliary tape 3 is provided at a position close to one side of the rice ball at the time of packaging. In this example, the wider opening auxiliary tape 3 is preferable, and the width of the rice ball to be packaged can be 40% or more and 80% or less.

開封補助テープ３を引いて開封すると開封補助テープ３があった部分は開口となり、その左右の部分の包装シートが握り飯の広い面ｘ１に残る。ここで、開封補助テープ３の幅を広くすると握り飯の広い面ｘ１に残る包装シートが小さくなる。そうなると、握り飯に直接触れないようにして握り飯を把持することが難しくなる。この実施形態では開封補助テープ３を包装シート２の幅中央に対してずらすことにより、開口部のどちらか一方の側部には包装シート２が幅広く残る。この広く残った包装シート２をつまめば、握り飯ｘに直接触れないようにして握り飯ｘを持つことができる。特に本例では握り飯の広い面ｘ１の左側に包装シート２が幅広く残るようになっている。左手で広い面ｘ１の左側をつまんで握り飯ｘを保持し、右手で開封補助テープ３を引くことにより開封することができる。 When the opening assist tape 3 is pulled and opened, the portion where the opening assist tape 3 is located becomes an opening, and the wrapping sheets on the left and right portions remain on the wide surface x1 of the rice ball. Here, if the width of the opening auxiliary tape 3 is widened, the wrapping sheet remaining on the wide surface x1 of the rice ball becomes small. In that case, it becomes difficult to grasp the rice balls without directly touching them. In this embodiment, by shifting the opening auxiliary tape 3 with respect to the center of the width of the packaging sheet 2, the packaging sheet 2 remains widely on either side of the opening. By pinching the wide remaining packaging sheet 2, the rice ball x can be held without directly touching the rice ball x. In particular, in this example, the packaging sheet 2 remains widely on the left side of the wide surface x1 of the rice ball. It can be opened by pinching the left side of the wide surface x1 with the left hand to hold the rice ball x and pulling the opening auxiliary tape 3 with the right hand.

このように開封補助テープ３を包装シート２の幅中央に対してずらして設ける握り飯用包装材や握り飯用包装材原反は例がなく、新規な外観を有し、意匠性が高い。この握り飯用包装材で包装された包装握り飯も、新規な外観を有し、開封時においてもさらに特徴のある外観となる。 As described above, there is no example of a rice ball wrapping material or a rice ball wrapping material raw fabric in which the opening auxiliary tape 3 is provided so as to be offset from the center of the width of the wrapping sheet 2, and it has a new appearance and high design. The packaged rice balls wrapped with this rice ball packaging material also have a new appearance, and even when opened, the appearance is even more distinctive.
