Description

 本発明は、乾燥食品、特に、熱湯を注いで食することができる乾燥した即席麺等の塊状の食品を収容したり、冷凍品や冷蔵品等の低温のものを収容したりするのに最適な食品用の断熱容器に関する。 The present invention is suitable for storing dry foods, especially bulk foods such as dried instant noodles that can be poured with boiling water, or for storing low-temperature foods such as frozen or refrigerated products. The present invention relates to an insulated container for food.

 従来、インスタント即席麺(乾燥麺、スナック麺、カップ入り味噌汁)等の即席食品や、ホットコーヒーあるいは非常に冷い飲料等の容器は、火傷の危険や持ち易さを考慮して、容器自体に断熱の工夫が施されている。 Conventionally, containers for instant foods such as instant instant noodles (dried noodles, snack noodles, miso soup in cups), hot coffee or very cold beverages, etc., have to be placed on the container itself in consideration of the danger of burns and ease of holding. Insulation is applied.

 例えば、上記断熱容器としては、発泡スチロール等の発泡樹脂成形や射出成形により形成したものが採用されている。特に最近では、環境的に優れたものが社会的に要求されていることから、ポリプロピレンを材料とする射出成形により形成した容器が使用されつつあるのが現状である。 For example, as the above-mentioned heat-insulating container, one formed by foaming resin molding such as styrene foam or injection molding is employed. Particularly, in recent years, containers that are formed by injection molding using polypropylene as a material are being used at present because environmentally superior materials are demanded by society.

 かかる射出成形による容器は、縦リブを容器本体の外周面に放射状に設けることにより、容器内に注がれた熱湯等の熱が容器を把持する指に伝わらないようになっている。 射出 In such a container formed by injection molding, the vertical ribs are provided radially on the outer peripheral surface of the container main body, so that heat such as boiling water poured into the container is not transmitted to the fingers holding the container.

 上記断熱容器は、軽量化を図ること及び高価になるのを避ける必要がある。そのための手段として、容器の肉厚を可及的に薄くして樹脂材料を少なくすることが考えられる。 It is necessary to reduce the weight of the above-mentioned insulated container and to avoid becoming expensive. As a means for achieving this, it is conceivable to reduce the thickness of the container as much as possible to reduce the resin material.

 しかしながら、容器の肉厚を薄くすると、強度が弱くなる欠点がある。しかも、特に熱湯を容器に注いだ場合には、容器自体が軟化して変形しやすくなり、更に強度が低下することとなる。 す る と However, when the thickness of the container is reduced, there is a disadvantage that the strength is weakened. In addition, especially when hot water is poured into the container, the container itself is softened and easily deformed, and the strength is further reduced.

 そこで、本発明は上記問題を解決すべくなされたもので、断熱性に優れ且つ適度な強度が確保できると共に軽量化を図ることができる食品用の断熱容器を提供することを課題とする。 Accordingly, an object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a heat-insulating container for food which has excellent heat insulating properties, can secure appropriate strength, and can be reduced in weight.

 本発明は、上記課題を解決すべく食品用の断熱容器としてなされたものであり、本発明に係る食品用の断熱容器としての特徴は、有底筒状の容器本体3の開口上縁にフランジ部2が形成され、且つ、容器本体3の外周面に、上下方向のリブ7が放射状に突設するように、射出成形により成形されて熱収縮性を有するラベルが外嵌装着される食品用の断熱容器において、容器本体3の底面から開口上縁までの中央位置以上の一カ所に、周壁3aを凹凸状に形成してなる補強手段が容器本体3の周方向に設けられていることにある。 The present invention has been made as a heat-insulating container for food in order to solve the above-mentioned problem, and the feature of the heat-insulating container for food according to the present invention is that a flange is provided on the upper edge of the opening of the bottomed cylindrical container body 3. For a food to which a heat-shrinkable label molded by injection molding is externally fitted so that a portion 2 is formed and a vertical rib 7 protrudes radially on the outer peripheral surface of the container body 3. In the heat-insulating container of (1), reinforcing means formed by forming the peripheral wall 3a in an uneven shape at one or more positions at the center position from the bottom surface of the container body 3 to the upper edge of the opening is provided in the circumferential direction of the container body 3. is there.

 そして、容器本体3の被把持部分となる周壁3aは、凹凸状の補強手段が形成されていることから、凹凸状部分はリブ7と共に周壁3aの強度を向上させることができる。しかも、周壁3aは、表裏面を凹凸状に形成することにより、把持強度が高められることから樹脂材料を少なくでき、コストの低減及び軽量化を期待できる。 Since the peripheral wall 3a serving as the gripped portion of the container body 3 is formed with the uneven reinforcing means, the uneven portion can improve the strength of the peripheral wall 3a together with the ribs 7. In addition, since the peripheral wall 3a is formed with irregularities on the front and back surfaces, gripping strength is enhanced, so that the resin material can be reduced, and cost reduction and weight reduction can be expected.

 しかも、前記周壁3aは、環状の上部周壁部9aと下部周壁部9bとが水平環状の接続部10を介して階段状に連続するように形成されてなるのが好ましい。 In addition, it is preferable that the peripheral wall 3a is formed such that the annular upper peripheral wall 9a and the lower peripheral wall 9b are connected in a stepwise manner via the horizontal annular connecting portion 10.

 更に、前記上部周壁部9aの下端には、補助片14が、前記下部周壁部9bとの間で所定の間隔を有するように、下方に延設され、各補助片14の両端は各リブ7に連結され、前記接続部10と補助片14とで補強手段を構成してなるのが好ましい。 Further, at the lower end of the upper peripheral wall portion 9a, an auxiliary piece 14 is extended downward so as to have a predetermined space between the lower peripheral wall portion 9b and both ends of each auxiliary piece 14 It is preferable that the connecting portion 10 and the auxiliary piece 14 constitute reinforcing means.

 かかる場合には、周壁3aと補助片14とにより二重壁構造とすることができ、更に容器本体3の強度を向上させることができる。しかも、補助片14と周壁3aとの間には空間17が形成されているため、例えば容器本体3に熱湯を注いだ場合であっても、補助片14には熱が伝わり難い。 In such a case, the peripheral wall 3a and the auxiliary piece 14 can form a double wall structure, and the strength of the container body 3 can be further improved. Moreover, since the space 17 is formed between the auxiliary piece 14 and the peripheral wall 3a, even when hot water is poured into the container body 3, for example, heat is hardly transmitted to the auxiliary piece 14.

 また、前記補強手段は、底面3bから開口上縁までの50〜70%の高さ位置に設けられているのが好ましい。 The reinforcing means is preferably provided at a height of 50 to 70% from the bottom surface 3b to the upper edge of the opening.

 以上のように本発明は、容器本体の底面から開口上縁までの中央位置以上の一カ所に、周壁部を凹凸状に形成してなる補強手段が容器本体の周方向に設けられているので、断熱性に優れ且つ適度な強度が確保できると共に、強度確保のための厚肉部分を設ける場合に比し軽量化を図ることができる。 As described above, according to the present invention, at one location or more from the center position from the bottom surface of the container body to the upper edge of the opening, the reinforcing means formed by forming the peripheral wall portion in an uneven shape is provided in the circumferential direction of the container body. In addition, excellent heat insulating properties and appropriate strength can be secured, and the weight can be reduced as compared with the case where a thick portion for securing strength is provided.

 以下、本発明の実施の形態について図面を参照しながら説明する。
 図1〜図3は本発明の第一実施の形態を示し、本実施形態の容器は、乾燥食品の例としての即席カップ麺の塊(乾燥麺)を収容するものを例示する。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIGS. 1 to 3 show a first embodiment of the present invention, and the container of the present embodiment exemplifies a container for holding a mass of instant cup noodles (dry noodles) as an example of dry food.

 前記容器1は、ポリプロピレン、高密度ポリエチレン等のプラスチック材料から形成された耐熱性を有するカップ形(有底筒状)の容器本体3を備え、その開口上縁には、断面コの字状のフランジ部2が設けられ、該フランジ部2はアルミ箔と合成樹脂フィルムや紙等のラミネート材等からなるシール蓋(図示省略)により剥離自在に密封される。 The container 1 is provided with a heat-resistant cup-shaped (bottomed cylindrical) container body 3 made of a plastic material such as polypropylene or high-density polyethylene, and has a U-shaped cross section at the opening upper edge. A flange portion 2 is provided, and the flange portion 2 is peelably sealed by a sealing lid (not shown) made of a laminated material such as aluminum foil and a synthetic resin film or paper.

 前記容器本体3は、下方に行くにしたがって直径が小さくなるように、射出成形により成形されている。容器本体3の周壁3aの外周面には、多数のリブ7が放射状に突設され、各リブ7は、容器本体3の上下方向に連続して設けられている。容器本体3の上部には、円筒状で且つ表面が凹凸のない平坦なリブの設けられていない部分(大径部)5が形成され、該大径部5に各リブ7の上端が接続され、各リブ7の上端と大径部5の表面5aは面一となっている。 容器 The container body 3 is formed by injection molding so that the diameter decreases as going downward. On the outer peripheral surface of the peripheral wall 3 a of the container main body 3, a number of ribs 7 are protruded radially, and each rib 7 is provided continuously in the vertical direction of the container main body 3. At the upper part of the container body 3, a portion (large-diameter portion) 5 which is cylindrical and has no flat ribs with no uneven surface is formed, and the upper end of each rib 7 is connected to the large-diameter portion 5. The upper end of each rib 7 and the surface 5a of the large diameter portion 5 are flush.

 各リブ7間の容器本体3の周壁3aは表裏面が凹凸状に形成されている。即ち、周壁3aは、複数(本実施の形態では2段)の環状の周壁部9a,9bが階段状に連続するように形成されている。 周 The peripheral wall 3a of the container main body 3 between the ribs 7 is formed with uneven front and back surfaces. That is, the peripheral wall 3a is formed so that a plurality of (two steps in the present embodiment) annular peripheral wall portions 9a and 9b are continuous in a stepwise manner.

 上部周壁部9aは、前記大径部5よりも小径で且つ水平環状の第一接続部13を介して大径部5と接続されたテーパー状の上部テーパー部11aと、該上部テーパー部11aから下方に延設された略同一直径のストレート部11bとから構成されている。そして、該ストレート部11bの下端が、水平環状の第二接続部10を介して下部周壁部9bの上端に接続されている。尚、前記第一接続部13の上面が、例えば乾燥食品を食する際に容器本体3内に入れる熱湯の位置を示す入り目線となり、該入り目線13aは、前記開口上縁の近傍に設けられている。 The upper peripheral wall portion 9a has a tapered upper tapered portion 11a having a smaller diameter than the large diameter portion 5 and connected to the large diameter portion 5 via the horizontal annular first connection portion 13, and from the upper tapered portion 11a. And a straight portion 11b of substantially the same diameter extending downward. Then, the lower end of the straight portion 11b is connected to the upper end of the lower peripheral wall portion 9b via the horizontal annular second connection portion 10. The upper surface of the first connection portion 13 serves as a score line indicating the position of hot water to be put into the container body 3 when eating dry food, for example, and the score line 13a is provided near the upper edge of the opening. ing.

 また、ストレート部11bの下端には、下向きの補助片14が、前記下部周壁部9bとの間で所定の間隔を有し、且つ、両端が各リブ7に連結されるように、容器本体3の周方向に形成されている。ここで、前記第二接続部10と補助片14とで補強手段が構成され、補強手段を構成する補助片14の下端は、前記入り目線13aよりも下方で且つ容器本体の底面3bから開口縁までの中央位以上の一カ所に設けられている。更には、補強手段は、底面3bから開口上縁までの50乃至70%の範囲の高さにあるのが好ましい。また、リブ7の先端部は、前記補助片14よりも突設され、しかも、前記下部周壁部9bのテーパー角度と略平行に傾斜している。 At the lower end of the straight portion 11b, a downwardly-facing auxiliary piece 14 is provided at a predetermined distance from the lower peripheral wall portion 9b, and both ends are connected to the respective ribs 7 so as to be connected. Are formed in the circumferential direction. Here, the second connecting portion 10 and the auxiliary piece 14 constitute a reinforcing means, and the lower end of the auxiliary piece 14 constituting the reinforcing means is located below the line of sight 13a and from the bottom surface 3b of the container body to the opening edge. It is located in one place above the central position. Furthermore, the reinforcing means is preferably at a height in the range of 50 to 70% from the bottom surface 3b to the upper edge of the opening. The tip of the rib 7 protrudes from the auxiliary piece 14 and is inclined substantially parallel to the taper angle of the lower peripheral wall 9b.

 前記下部周壁部9bの内周面で且つ前記補強手段の下方には、係止用リブ15が周方向に突設されている。従って、図3に示す如く複数の容器1を重ね合わせた際に、該係止用リブ15に上方の容器1のリブ7等が係止されるようになっている。尚、17は前記底壁3bから下方に一体成形された筒状の脚部である。 A locking rib 15 is provided on the inner peripheral surface of the lower peripheral wall portion 9b and below the reinforcing means in a circumferential direction. Therefore, when a plurality of containers 1 are overlapped as shown in FIG. 3, the ribs 7 and the like of the upper container 1 are locked by the locking ribs 15. Reference numeral 17 denotes a cylindrical leg integrally formed downward from the bottom wall 3b.

 前記容器本体3の周壁3aの外周には、熱収縮性を有する筒状のラベル18が外嵌装着されている。該ラベル18の内面には、ラベル18の熱収縮時の熱で活性化して接着性を発揮する感熱接着剤が塗布されており、ラベル18の上部が、感熱接着剤を介して容器本体3の大径部5の表面5aに接着されている。従って、ラベル18はリブ7に沿ってテーパー状になるが、容器本体3から下方にずれ落ちることはなく保持される。また、ラベル18によって美しい印刷表示が得られる。 熱 A heat-shrinkable cylindrical label 18 is fitted around the outer periphery of the peripheral wall 3a of the container body 3. The inner surface of the label 18 is coated with a heat-sensitive adhesive which is activated by heat at the time of heat shrinkage of the label 18 and exhibits adhesiveness, and the upper portion of the label 18 is attached to the container body 3 via the heat-sensitive adhesive. It is adhered to the surface 5a of the large diameter portion 5. Therefore, the label 18 is tapered along the rib 7, but is held without falling down from the container body 3. Also, a beautiful printed display can be obtained by the label 18.

 上記構成からなる容器1内に、例えば熱湯を注いだ場合に、容器本体3の把持部分に相当する周壁3aが熱くなっても、リブ7は放熱効果を有するため、リブ7先端面は比較的温度が低いと共に把持する指との接触面積が小さいことから、格別の熱さを感じることはない。 For example, when hot water is poured into the container 1 having the above configuration, even if the peripheral wall 3a corresponding to the gripping portion of the container body 3 becomes hot, the rib 7 has a heat radiation effect, so the tip end surface of the rib 7 is relatively small. Since the temperature is low and the contact area with the gripping finger is small, the user does not feel any particular heat.

 しかも、容器本体3を比較的強固に把持しても、容器本体3の周壁3aの略中央位置(変形しやすい位置)には補強手段(第二接続部10と補助片14)が形成されていることから、周壁3aが平坦面である場合に比し、直径方向の強度が向上し、容器本体を把持した際に変形し難くなる。また、一般的に合成樹脂は加熱されることにより、若干軟化して剛性が低下する傾向にあるが、仮に、容器本体と共に補助片14が加熱された場合であっても、各リブ7は、補助片14よりも突出していることから、リブ7は加熱されがたく、リブ7の強度が低下するのを防止できる。しかも、入り目線13aよりも上方に熱湯に直接接しないフランジ部2が設けられていることから、該フランジ部2は前記リブ7と共に熱湯が入れられているにもかかわらず、容器本体3の剛性を維持することが可能である。 Moreover, even if the container main body 3 is relatively firmly gripped, reinforcing means (the second connecting portion 10 and the auxiliary piece 14) are formed at a substantially central position (a position where it is easily deformed) of the peripheral wall 3a of the container main body 3. As a result, the strength in the diametrical direction is improved as compared with the case where the peripheral wall 3a is a flat surface, and it is difficult to deform when the container body is gripped. In general, when the synthetic resin is heated, it tends to be slightly softened and its rigidity tends to be reduced. However, even if the auxiliary piece 14 is heated together with the container body, each rib 7 is Since the ribs 7 protrude from the auxiliary pieces 14, the ribs 7 are hardly heated, so that the strength of the ribs 7 can be prevented from lowering. Moreover, since the flange portion 2 which is not directly in contact with the hot water is provided above the score line 13a, the flange portion 2 has the rigidity of the container body 3 despite the hot water being put together with the ribs 7. It is possible to maintain

 更に、容器本体3の周壁3aの内周面側にも外周面に対応する階段状に形成していることから、補強のための厚肉部を設けることなく周壁部の肉厚を薄くすることができ、樹脂材料を少なくして材料コストを低減できる共に、軽量化も図ることができる。 Furthermore, since the inner peripheral surface of the peripheral wall 3a of the container body 3 is also formed in a stepped shape corresponding to the outer peripheral surface, the thickness of the peripheral wall portion can be reduced without providing a thick portion for reinforcement. Therefore, the material cost can be reduced by reducing the resin material, and the weight can be reduced.

 また、容器本体3は、上記の如くリブ7を傾斜状態に設け、且つ周壁3aを略鉛直またはリブ7と同方向に少し傾斜させ、補助片14を所定の力で弾性変形可能な一カ所に設けていることから、成形型から型抜き(容器本体の上下方向の型開き)を容易に行える。また、本実施の形態は、最小限の補強手段(容器本体3の内周面の段差の数を少なくしている)により、必要な強度を確保すると共に箸等が引っかかるのを防止している。 Further, the container body 3 is provided with the ribs 7 in the inclined state as described above, and the peripheral wall 3a is substantially vertically or slightly inclined in the same direction as the ribs 7, so that the auxiliary piece 14 can be elastically deformed by a predetermined force in one place. Since it is provided, the mold can be easily removed from the mold (opening of the container body in the vertical direction). In this embodiment, the necessary strength is ensured and the chopsticks are prevented from being caught by the minimum reinforcing means (the number of steps on the inner peripheral surface of the container body 3 is reduced). .

 図4は本発明の第二実施の形態を示す。本実施の形態の容器本体3は、周壁3aが上部周壁部9aと下部周壁部9bとから構成され、第二接続部10と補助片14とから補強手段を構成しているのは、前記第一実施の形態と同様である。前記フランジ部2が、水平部のみから構成されている。また、前記大径部5の下端には、補助片14aが、前記上部壁部の上部テーパー部11aとの間で所定の間隔を有し且つ両端は両側のリブ7に連結するように、下方に突設されている。また、補助片14aを入り目線13aと同一又はその付近の高さに設置することにより、断面コの字状のフランジ部と同様の強度を維持したフラットなフランジ部12を実現できる。フランジ部12をフラットにすることにより、蓋のシール加工性を上げ、フランジ部12の幅を小さくすることが可能になる。尚、本実施の形態においても、前記第一実施の形態と同様に熱収縮性ラベル18を装着することもできる。 FIG. 4 shows a second embodiment of the present invention. In the container main body 3 of the present embodiment, the peripheral wall 3a is composed of an upper peripheral wall 9a and a lower peripheral wall 9b, and the second connecting portion 10 and the auxiliary piece 14 constitute reinforcing means. This is the same as in one embodiment. The flange portion 2 is composed of only a horizontal portion. At the lower end of the large-diameter portion 5, an auxiliary piece 14a is provided with a predetermined space between the upper tapered portion 11a of the upper wall and a lower end so that both ends are connected to the ribs 7 on both sides. It is protruded. In addition, by installing the auxiliary piece 14a at the same height as or near the entry line 13a, it is possible to realize the flat flange portion 12 maintaining the same strength as the U-shaped cross-section flange portion. By making the flange portion 12 flat, the sealing processability of the lid can be increased, and the width of the flange portion 12 can be reduced. In this embodiment, the heat-shrinkable label 18 can be attached similarly to the first embodiment.

 本発明は上記の実施の形態に限定されるものではなく、例えば、容器は熱湯で調理する乾燥麺を収容するもの以外に、ホットコーヒーあるいは非常に冷い飲料等用の容器であっても良い。更に、容器本体3の形状も平面視円形に限らず、矩形状や楕円状の任意の形状であっても良い。 The present invention is not limited to the above-described embodiment. For example, the container may be a container for hot coffee or a very cold beverage, etc., in addition to a container for storing dried noodles cooked with hot water. . Further, the shape of the container body 3 is not limited to a circular shape in a plan view, but may be any rectangular shape or an elliptical shape.
