Description

本発明は、発泡樹脂や紙製等の各種断熱構造を有する断熱容器に関しての紙製の包装体であって、特に即席麺等の御椀形状の発泡樹脂等の断熱容器の外周を包装する紙製の包装体に関する。   The present invention relates to a paper package relating to a heat insulating container having various heat insulating structures such as foamed resin and paper, and in particular, paper that wraps the outer periphery of a heat insulating container such as a bowl-shaped foamed resin such as instant noodles. It relates to a packaging body made.

従来より、ポリスチレン樹脂系発泡シート等を用いて即席麺等の御椀形状に容器を形成し、これを断熱容器として用いて多用しているものである。
この場合、例えば該容器の表面における印刷等はよりキレイに行なうために他の樹脂フィルムを用いて、該容器の外周を該樹脂フィルムで覆うものが用いられてきている。
Conventionally, a container is formed in a bowl shape such as instant noodles using a polystyrene resin foam sheet or the like, and this is often used as a heat insulating container.
In this case, for example, in order to perform printing on the surface of the container more clearly, another resin film is used and the outer periphery of the container is covered with the resin film.

例えば、特開平6−33999号(特許文献1) や特開2001−175179号(特許文献2)等が存在する。
更に、断熱性を高めるために不織布との重積等によってラベルを構成する特開平8−126663号(特許文献3)や特開2005−97772号(特許文献4)、特開2005−338304号(特許文献5)が存在する。

以上の様に、ポリスチレン樹脂系発泡シート等を用いた御椀形状の即席麺等の断熱容器は、その外周に対して印刷可能な層を設けるために例えば熱収縮性フィルムを該容器の外周に位置させるものである。
この場合、特に御椀形状である開口部が広縁からなり、ほぼ該容器の中央部までは若干量該開口口径を少しずつだけ狭めるが、底部近傍で急に口径を狭く構成して大容量の内容量を確保する略御椀形状である丼形の容器にあっては、該容器の底部を除く外周面に該包装材できっちりと覆うためには、低温で収縮性のある樹脂フィルムを用いてきっちりと密着して配置するか、或いはそもそも発泡樹脂シートを積層シートとして構成して、一体にて成形することが必要であった。
As described above, a heat-insulating container such as a bowl-shaped instant noodle using a polystyrene resin foam sheet or the like is provided with a heat-shrinkable film on the outer periphery of the container in order to provide a printable layer on the outer periphery. It is to be positioned.
In this case, the opening in the shape of a granite has a wide edge, and the opening diameter is slightly narrowed little by little to almost the center of the container. In the case of a bowl-shaped container having a substantially bowl shape that secures the inner volume, a resin film that is shrinkable at a low temperature is used to cover the outer peripheral surface of the container excluding the bottom part with the packaging material. It has been necessary to arrange them in close contact with each other or to form a foamed resin sheet as a laminated sheet and mold it integrally.

従って、このように構成した場合、例えば予め印刷した樹脂フィルムにおいては、断熱容器に熱収縮によって密着成形する場合や多層シートでの一体成形の場合には、どうしても収縮や成形に伴うズレ等が生ずるものであり、印刷状態の高品質化は図りにくいものであった。
更に、従来は、容器自体の形状が略御椀形状である丼形の容器であることから、概容器の外周が円弧形状であって、底部方向において急に幅是間に狭まる形状であることから該形状の外周にキレイに包装材を配置するためには、該形状に合致するような伸縮性を有する樹脂材が用いられてきたものであり、係るためにどうしても樹脂材が多用されるものであった。
Therefore, in the case of such a configuration, for example, in the case of a resin film printed in advance, when it is formed by close contact with a heat-insulating container by heat shrinkage or when it is integrally formed with a multilayer sheet, there is inevitably shrinkage or misalignment associated with forming. Therefore, it was difficult to improve the quality of the printed state.
Furthermore, conventionally, since the container itself is a bowl-shaped container having a substantially bowl shape, the outer periphery of the container is generally arc-shaped and has a shape that suddenly narrows in the width direction in the bottom direction. In order to arrange the packaging material neatly on the outer periphery of the shape, a resin material having elasticity that matches the shape has been used, and for this reason, a resin material is inevitably used frequently. Met.

これは紙材を用いた場合には、容器の外周に巻きつけた場合には底部方向に皺が生じてしまうものであるか、或いは底部方向が容器から離れて浮いた状態となるか或いは幅狭の帯状の巻き付けだけしかできないものであり、実用性に欠けていたものである。
特に印刷の容易性や見栄えのよさ等と共に、資源としてのリサイクル性或いは使用者側の要請等各種の面で現在紙の活用が望まれているが、前記の点でこのような御椀形の断熱容器には用いられてはいなかったものである。
係るため、このようなポリスチレン樹脂系発泡シート等を用いた即席麺等の御椀形状の断熱容器の底部を除く外周面に該容器に合致した形状で該外周面を覆うことのできる紙製包装材の提供を課題とするものである。
If paper is used, this will cause wrinkles in the bottom direction when wrapped around the outer periphery of the container, or the bottom direction will float away from the container, or the width It can only be wound in a narrow band, and lacks practicality.
In particular, it is desired to use paper in various aspects such as recyclability as a resource or user's request in addition to ease of printing and appearance, etc. It was not used for an insulated container.
Therefore, a paper packaging that can cover the outer peripheral surface with a shape matching the container on the outer peripheral surface excluding the bottom of a bowl-shaped heat insulating container such as instant noodles using such a polystyrene resin foam sheet or the like The issue is to provide materials.

図1乃至図3は、本発明に係る断熱容器の外周を包装する紙製の包装体の製造工程の一例を示す図である。
先ず図1に示す構成は、略扇状の紙製のシート1と、これを巻き込むための成形芯金2であるマンドレルからなるものである。
先ず成形芯金2は、ポリスチレン樹脂系発泡シート等を用いた御椀形状の即席麺等の断熱容器の外周形を模った形状であって、上縁部20は広縁であって、該容器の中央部21までは若干量該開口口径を少しずつだけ狭めるが、底部近傍23で急に口径を狭く構成した略御椀形状である丼形の容器をかたどった形状よりなるものである。
1 to 3 are views showing an example of a manufacturing process of a paper package for packaging the outer periphery of a heat insulating container according to the present invention.
First, the structure shown in FIG. 1 consists of a substantially fan-shaped paper sheet 1 and a mandrel which is a cored bar 2 for winding the sheet.
First, the molded core 2 has a shape imitating the outer peripheral shape of a heat-insulating container such as a bowl of instant noodles using a polystyrene resin foam sheet or the like, and the upper edge portion 20 has a wide edge. The opening diameter is slightly narrowed little by little up to the central portion 21 of the container, but it has a shape shaped like a bowl-shaped container having a substantially bowl shape in which the diameter is suddenly narrowed in the vicinity of the bottom 23.

この成形芯金2に対して配置した紙製のシート1を、更に例えば両側からアーム状のフラップによって成形芯金2に巻きつけて容器形状に成形するものである。
この場合、シート1は略扇状よりなり、この短円弧辺部方向に向かって多数の切り欠き部を有するものである。
この切り欠きは、シート1の任意の位置を頂点13として短円弧辺部11に向かって略三角形状に切り広がった切り欠きであり、該略三角形の切り欠きを構成するシート地1の切り欠き辺部12が鋭角を挟んで連設形成されているものである。
The paper sheet 1 disposed with respect to the molding core 2 is further wound around the molding core 2 by arm-shaped flaps from both sides, for example, and molded into a container shape.
In this case, the sheet 1 is substantially fan-shaped and has a large number of notches in the direction of the side of the short arc.
This notch is a notch that is cut out and spreads in a substantially triangular shape toward the short arc side portion 11 with an arbitrary position of the sheet 1 as a vertex 13, and the notch of the sheet base 1 constituting the substantially triangular notch. The side part 12 is continuously formed with an acute angle in between.

従って、この部分が切り取られていることから、アーム状のフラップによってこのシート1を巻きつけた場合に、シート地1の部分の夫々一の三角形の該切り欠きを構成する切り欠き辺部12同士が接し又は一部重なって形成され、底部方向の形状をすぼめた形状に形成できる。
この場合、略三角形状として図面上明示するがこれに限らず切り欠き辺部12が夫々円弧形状に形成し、二等辺三角形や正三角形ではなく、弧状辺よりなる略三角形の形状をもって構成したものであってもよい。
尚、長円弧辺部10は、本図構成においては弧状に形成されているものである。
Accordingly, since this portion is cut off, when the sheet 1 is wound by the arm-shaped flap, the cutout side portions 12 constituting the cutouts of the triangles of the respective portions of the sheet base 1 are mutually connected. Are in contact with each other or partly overlapped, and the shape in the bottom direction can be reduced.
In this case, it is clearly shown on the drawing as a substantially triangular shape, but the present invention is not limited to this, and the cut-out side portions 12 are each formed in a circular arc shape, and are configured with a substantially triangular shape composed of arc-shaped sides instead of an isosceles triangle or regular triangle. It may be.
In addition, the long circular arc side part 10 is formed in the arc shape in the structure of this figure.

図2は、アーム状のフラップによってこの紙製のシート1を成形芯金2に巻きつけた一例を示す図である。
このように成形芯金2に巻きつけたシート1は、略御椀形状である略丼形状の容器をかたどった形状となり、該シート1は紙製の包装体を構成するものであって、特に外表面はきれいな曲面構成で形成できるものである。
この場合シート1の切り欠き辺部12はきれいに接して形成されるものの他一部重なるものであってももちろんよい。
FIG. 2 is a view showing an example in which the paper sheet 1 is wound around the cored bar 2 by an arm-shaped flap.
In this way, the sheet 1 wound around the cored bar 2 is shaped like a substantially bowl-shaped container that is substantially bowl-shaped, and the sheet 1 constitutes a paper package, and in particular, The outer surface can be formed with a clean curved surface configuration.
In this case, the cut-out side portion 12 of the sheet 1 may of course be partly overlapped in addition to what is formed in good contact.

尚、この場合成形芯金2の底部において、特段シート1は巻き付かれてはいないものである。
更に必要に応じて糊代部等を設けて巻きつけたシート1をこの形状で接着成形してもよい。
更に切り欠き辺部12においても同様に接着部材を用いて接着成型してもよい。
もとよりフラップできっちりと成形するものであってもよい。

FIG. 4 is a diagram showing an example of a paper sheet base, and has a number of notches in the direction of the short arc side 11 of the substantially fan-shaped sheet 1 in the direction of the end side. .

この切り欠きは、シート1の任意の位置を頂点13として短円弧辺部11に向かって略三角形状に切り広がった切り欠きであり、該略三角形の切り欠きを構成するシート地の切り欠き辺部12が鋭角をもって連設形成されているものである。
この切り欠きは、前記のように一例であり、例えば切り欠き辺部12が弧状辺からなるものであっても、或いは角度を任意に変化させた辺であってもよく、又切り欠きの頂点13部分が任意位置よりなるものであっても、又夫々の切り欠きの頂点位置が異なるものであってもいずれでもよい。
This notch is a notch that extends in an approximately triangular shape toward the short arc side portion 11 with an arbitrary position of the sheet 1 as the apex 13, and the notch side of the sheet ground that constitutes the approximately triangular notch The part 12 is formed continuously with an acute angle.
This notch is an example as described above. For example, the notch side portion 12 may be an arcuate side, or may be a side whose angle is arbitrarily changed, or the apex of the notch. Even if 13 parts consist of arbitrary positions, and the vertex position of each notch may differ, either may be sufficient.

又、この略扇状のシート1の形態は、一例であり、必要に応じて幅や高さ或いは曲線の程度を定めればよいものである。
尚、該シートに予め印刷などを施し、これを更に成形芯金に巻き込んで成形するものであってももちろんよい。
これらの場合、該紙製シートは薄手の紙製シートが最もよいが、これに限らず、巻き込み可能な厚手の紙製のシートをもって構成してもよい。
更に、紙を用いた複合シート或いは多層シート等であってもよいのはもちろんである。
従って、少なくとも紙製シートからなるものであるが、これに樹脂シートをラミネート等した紙製のシートでもよいものである。
Moreover, the form of this substantially fan-shaped sheet | seat 1 is an example, and what is necessary is just to define the width | variety, height, or the extent of a curve as needed.
