Description
本発明は、外箱内に並べた際に小分容器間の隙間を塞ぐことができ、更に運搬時の衝撃等による小分容器の浮き上がりも防止できる食品用小分容器、及びそれを用いた食品容器セットに関するものである。 The present invention relates to food portion containers that can seal gaps between the containers when arranged inside an outer box and can also prevent the containers from floating up due to shocks during transport, and to a food container set that uses the same.
弁当やおせち等に使用される食品容器としては、外箱の内側に外箱と一体に、または外箱と別体の仕切りを設けて、仕切りで区切られた各スペースにご飯や主菜、副菜などを収容するものが一般的に知られている。また従来においては、各食品を小分容器に入れてから外箱に詰められるようにしたものも知られている(例えば、特許文献１～４参照)。 As food containers used for bento lunches, osechi dishes, etc., a commonly known type has partitions inside an outer box, either integrated with the outer box or separate from the outer box, and rice, a main dish, a side dish, etc. are stored in each space separated by the partitions. Conventionally, there are also known containers in which each food item is placed in a small container and then packed into the outer box (see, for example, Patent Documents 1 to 4).
しかしながら、特許文献１・２に記載されているような外箱に凹部を形成して、この凹部の位置や形状に合わせて小分容器を配置する構造では、小分容器の形状が凹部によって限定されてしまう。しかも、凹部を備えた外箱が必要となるため、既存の重箱等をそのまま使用できず、複雑な形状の外箱の製造により製品コストも高く付き易い。 However, in the structure described in Patent Documents 1 and 2, in which a recess is formed in the outer box and the portion containers are arranged according to the position and shape of this recess, the shape of the portion container is limited by the recess. Moreover, because an outer box with a recess is required, existing stacked boxes and the like cannot be used as is, and the production costs tend to be high due to the manufacturing of outer boxes with complex shapes.
また特許文献３・４に記載されている食品容器では、外箱に凹部を形成する必要はないものの、外箱内に複数の小分容器を並べるだけの構造であるため、弁当等を持ち運ぶ際に衝撃等で小分容器が浮き上がり、小分容器が斜めに大きく傾いて容器内の食品が隣の小分容器に食み出したり、食品のタレ等が隣の小分容器に流れ出る問題も生じ易い。 In addition, the food containers described in Patent Documents 3 and 4 do not require the formation of a recess in the outer box, but are structured to simply line up multiple small containers inside the outer box. This means that when carrying a lunch box or the like, the small containers can easily be lifted up by impact, causing the container to tilt significantly at an angle, causing food inside the container to spill over into adjacent small containers, or food sauces, etc. to flow into adjacent small containers.
また上記従来技術では、小分容器間に隙間が生じ易いため、その隙間から外箱の底面が露出して弁当等の見た目が損なわれ易い(例えば、金色の食品容器を並べたときに外箱の底面が隙間から露出して高級感が損なわれる等)。更に小分容器間に隙間が生じることで、その隙間から水分やタレ等が外箱の底面に液だれする問題も起き易い。 In addition, with the above-mentioned conventional technology, gaps tend to form between the small containers, which can expose the bottom of the outer box and ruin the appearance of the lunch box or the like (for example, when a gold-colored food container is placed next to it, the bottom of the outer box is exposed through the gap, ruining the luxurious look). Furthermore, the formation of gaps between the small containers can easily cause problems such as water or sauces dripping from the gap onto the bottom of the outer box.
本発明は、上記従来技術の問題を解決することを課題としており、要約すると容器形状の多様化が可能で、更に外箱内に並べた際に小分容器間の隙間を塞いで外観や液垂れの問題も解消でき、しかも、運搬時の衝撃等による小分容器の浮き上がりも防止できる食品用小分容器、及びそれを用いた食品容器セットを提供することにある。 The present invention aims to solve the problems of the prior art described above, and in summary, to provide a food portion container that allows for a variety of container shapes, can seal gaps between the portion containers when lined up inside an outer box to eliminate problems with appearance and dripping, and can prevent the portion containers from floating up due to shocks during transport, and a food container set using the same.
本発明者は、上記課題を解決する手段として、小分容器本体１を、多角形状の底面部11と、この底面部11の外周から上方に向けて外側にテーパ状に広がった胴部12とを有し、かつ、前記胴部12の開口部側には、底面部11側の下側部位12aよりも勾配が大きい上側部位12bが開口部側に受け口として形成し、更に前記小分容器本体１に、前記胴部12上端の口縁部12cが下方に折り返された垂下部13、並びにこの垂下部13の下端から外側に突き出したフランジ部14を形成する構成を採用した(図１参照)。 As a means for solving the above problems, the inventor has adopted a configuration in which the small-portion container body 1 has a polygonal bottom surface 11 and a body portion 12 that tapers outward from the outer periphery of the bottom surface 11 toward the top, and an upper portion 12b that has a steeper slope than the lower portion 12a on the bottom surface 11 side is formed as a receiving port on the opening side of the body portion 12, and further, the small-portion container body 1 is formed with a hanging portion 13 formed by folding back the rim portion 12c at the upper end of the body portion 12 downward, and a flange portion 14 that protrudes outward from the lower end of the hanging portion 13 (see Figure 1).
また本発明では、上記垂下部13を外側に向けて外側に広がったテーパ状に形成し、かつ、この垂下部13の勾配を胴部12の勾配よりも小さくすることで、小分容器本体１の平面視のサイズを抑えつつ垂下部13の変形を抑制することができる。 In addition, in the present invention, the hanging portion 13 is tapered outward and the slope of the hanging portion 13 is made smaller than the slope of the body portion 12, thereby suppressing deformation of the hanging portion 13 while reducing the size of the small-portion container body 1 in a plan view.
また本発明では、上記フランジ部14の出幅を1.0mm～3.0mmの範囲内で形成することによって、小分容器本体１の平面視のサイズを抑えつつフランジ部14同士を重なり易くすることができる。 In addition, in the present invention, the flange portions 14 are formed to have a protruding width within the range of 1.0 mm to 3.0 mm, which makes it easier for the flange portions 14 to overlap while keeping the size of the small-portion container body 1 in a plan view small.
また本発明では、少なくとも上記胴部12の上側部位12bおよび口縁部12cに光沢感のある色または柄を付すことにより、フランジ部14を目立ち難くすることができる。 In addition, in the present invention, by applying a glossy color or pattern to at least the upper portion 12b and the rim portion 12c of the body portion 12, the flange portion 14 can be made less noticeable.
また本発明では、上記食品用小分容器の小分容器本体１を外箱２内に敷き詰めて食品容器セットを構成することができ、その場合には、隣接する小分容器本体１・１のフランジ部14・14同士を上下に重なった状態で配置することができる。 In addition, in the present invention, the food container bodies 1 of the above-mentioned food containers can be arranged inside the outer box 2 to form a food container set, and in this case, the flange portions 14, 14 of adjacent food container bodies 1, 1 can be arranged in a vertically overlapping state.
本発明においては、多角形状の底面部を有する食品用小分容器において、胴部上端の口縁部が下方に折り返された垂下部、並びにこの垂下部の下端から外側に突き出したフランジ部を形成することにより、外箱内に小分容器を詰めた際に、隣り合う小分容器のフランジ部同士が重なり合うことで容器間の隙間を塞ぐことができる。 In the present invention, in a food portion container having a polygonal bottom surface, a hanging portion is formed in which the rim of the upper end of the body is folded downward, and a flange portion is formed that protrudes outward from the lower end of this hanging portion. When the portion containers are packed into the outer box, the flange portions of adjacent portion containers overlap with each other, thereby sealing the gap between the containers.
これにより、小分容器間の隙間から外箱の底面が露出して外観が損なわれる問題や、小分容器間の隙間から外箱の底面にタレ等が液だれする問題を解消できる。またフランジ部同士が重なり合うことで、フランジ部が下側に配置された小分容器の浮き上がりも防止できるため、弁当等を持ち運ぶ際も小分容器が大きく傾くような心配もない。 This eliminates the problem of the bottom of the outer box being exposed through the gaps between the small containers, spoiling the appearance, and the problem of sauces dripping onto the bottom of the outer box through the gaps between the small containers. In addition, because the flanges overlap, the small containers with the flanges on the bottom are prevented from floating up, so there is no need to worry about the containers tipping significantly when carrying lunch boxes, etc.
また本発明では、小分容器の胴部を、底面部の外周から上方に向けて外側にテーパ状に広がった形状とし、更にこの胴部に、底面部側の下側部位よりも勾配が大きい上側部位を開口部側に受け口として形成しているため、上側から見た小分容器の受け口の視認面積が大きくなって、相対的に視認面積の小さいフランジ部を目立ち難くすることができる。 In addition, in this invention, the body of the portion-portion container is shaped to taper outward from the outer periphery of the bottom surface toward the top, and the body is formed with an upper section that has a steeper slope than the lower section on the bottom surface side as a receiving port on the opening side, so the visible area of the receiving port of the portion-portion container when viewed from above is larger, making the flange, which has a relatively small visible area, less noticeable.
『第一実施形態』
本発明の第一実施形態を図１～図５に基づいて説明する。なお図中、符号１で指示するものは、小分容器本体であり、符号２で指示するものは、外箱である。また符号Ｓで指示するものは、食品容器セットである。
"First embodiment"
A first embodiment of the present invention will be described with reference to Figures 1 to 5. In the figures, reference numeral 1 denotes a small-portion container body, reference numeral 2 denotes an outer box, and reference numeral S denotes a food container set.
「食品容器セット」
[１]基本構成について
本実施形態においては、図１に示すように、平面視の形状が正方形型と長方形型の食品用小分容器の小分容器本体１・１’を外箱２の内側に敷き詰めて食品容器セットＳを構成している。また二種の小分容器本体１・１’は、図２～図４に示すように正方形または長方形の底面部11と、この底面部11の外周から上方に向けて外側にテーパ状に広がった胴部12とを有し、この胴部12には、底面部11側の下側部位12aよりも勾配の大きい上側部位12bを開口部側に受け口として形成している。
Food container set
[1] Basic Structure In this embodiment, as shown in Fig. 1, food container sets S are constructed by arranging food container bodies 1, 1', which are square and rectangular in plan view, inside an outer box 2. As shown in Figs. 2 to 4, the two types of food container bodies 1, 1' have a square or rectangular bottom surface 11 and a body 12 that tapers outward from the outer periphery of the bottom surface 11 toward the top, and the body 12 has an upper portion 12b, which has a steeper slope than the lower portion 12a on the bottom surface 11 side, formed as a receiving port on the opening side.
更に上記小分容器本体１・１’には、図５(a)に示すように胴部12上端の口縁部12cが下方に折り返された垂下部13を形成すると共に、この垂下部13の下端から外側に張り出したフランジ部14を形成して、外箱２内に敷き詰めたとき、図５(b)に示すように隣接する小分容器本体１・１’のフランジ部14・14同士が上下に重なった状態となっている。これにより小分容器本体１・１’の変形や浮き上がりを防止できるだけでなく、小分容器本体１・１’同士の隙間を隠すことができる。 Furthermore, in the above-mentioned small portion container bodies 1, 1', as shown in Fig. 5(a), the rim portion 12c at the upper end of the body portion 12 is folded downward to form a hanging portion 13, and a flange portion 14 is formed that projects outward from the lower end of this hanging portion 13, so that when they are laid out inside the outer box 2, the flange portions 14, 14 of adjacent small portion container bodies 1, 1' are stacked one on top of the other as shown in Fig. 5(b). This not only prevents the small portion container bodies 1, 1' from deforming or floating up, but also hides the gaps between the small portion container bodies 1, 1'.
[２]小分容器本体について
[2-1]材料
次に上記食品容器セットの各構成要素について説明する。まず小分容器本体１・１’の材料に関しては、本実施形態ではポリプロピレンを使用しているが、他の合成樹脂材料を使用することもでき、例えば、食品容器として汎用されているポリエチレンテレフタレート(ＰＥＴ樹脂)やポリエチレン、ポリアセタールなどを使用することもできる。また小分容器本体１の材料としては、真空成形が可能な熱可塑性樹脂の使用が好ましいが、熱硬化性樹脂や金属材料等を使用することもできる。
[2] About the small container
[2-1] Materials Next, each component of the food container set will be described. First, regarding the material of the small container body 1, 1', polypropylene is used in this embodiment, but other synthetic resin materials can also be used, such as polyethylene terephthalate (PET resin), polyethylene, polyacetal, etc., which are widely used as food containers. In addition, as the material of the small container body 1, it is preferable to use a thermoplastic resin that can be vacuum molded, but thermosetting resins, metal materials, etc. can also be used.
なお本実施形態では、熱可塑性樹脂フィルムを真空成形して小分容器本体１・１’を作製しているが、シート成形等の方法を採用することもできる。また熱可塑性樹脂フィルムの厚さに関しては、真空成形に好適な0.5mm～2.0mmの範囲とするのが好ましい。 In this embodiment, the small container bodies 1 and 1' are produced by vacuum forming a thermoplastic resin film, but methods such as sheet forming can also be used. The thickness of the thermoplastic resin film is preferably in the range of 0.5 mm to 2.0 mm, which is suitable for vacuum forming.
また本実施形態では、上記小分容器本体１・１’の材料に、容器間の隙間が目立たないように光沢感のある金色(黄色＋金属光沢)に着色した熱可塑性樹脂フィルムを使用しているが、黒色や赤色、白色等(不透明色)に着色したものを採用することもでき、また銀色(白＋金属光沢)などの金属光沢を有する他の色に着色することもできる。また単一色である必要もなく、例えば小分容器本体１・１’の底部11や胴部12に複数の色で柄を形成することもできる。また容器間の隙間が目立たないように胴部12の上側部位12bおよび口縁部12cのみに光沢感のある色または柄を付すこともできる。 In this embodiment, the material of the small container body 1/1' is a thermoplastic resin film colored in a glossy gold color (yellow + metallic luster) so that the gaps between the containers are not noticeable, but it can also be colored in black, red, white, etc. (opaque colors), or it can be colored in other colors with metallic luster, such as silver (white + metallic luster). It does not have to be a single color, and for example, a pattern can be formed in multiple colors on the bottom 11 and body 12 of the small container body 1/1'. Also, a glossy color or pattern can be applied only to the upper part 12b and the rim 12c of the body 12 so that the gaps between the containers are not noticeable.
[2-2]底部の形状
上記小分容器本体１・１’の底部11の形状に関しては、本実施形態では図３(a)(b)に示すように底面部11を正方形または長方形としているが、容器に収容する食品の種類に応じて三角形や五角形、台形または平行四辺形などの他の多角形状を採用することもできる。また本実施形態では、図３(a)(b)及び図４(a)(b)に示すように底部12の中央部位に上側に凸の隆起部を形成して食品を入れた際の底部12の変形を抑制している。また底部12には、材料名やリサイクルマーク、会社名、製品番号等の文字を凹凸により形成できる。
[2-2] Shape of Bottom In this embodiment, the bottom 11 of the above-mentioned small container body 1, 1' is a square or rectangular shape as shown in Figures 3(a) and (b), but other polygonal shapes such as a triangle, pentagon, trapezoid, or parallelogram can be used depending on the type of food to be stored in the container. In this embodiment, a convex protrusion is formed on the center of the bottom 12 as shown in Figures 3(a) and 4(a) and 4(b) to suppress deformation of the bottom 12 when food is placed in it. In addition, the bottom 12 can be formed with letters such as the name of the material, a recycling mark, a company name, and a product number by using protrusions and recesses.
[2-3]胴部の形状
上記小分容器本体１・１’の胴部12の形状に関しては、本実施形態では図２(a)(b)及び図４(a)(b)に示すように下側部位12aを勾配αが5度～20度の範囲内となるように形成し、上側部位12bを勾配βが20度～50度の範囲内となるように形成している。また胴部12の全高における下側部位12aと上側部位12bの上下比率については、６：１～２：１の範囲内となるようにしている。これにより小分容器本体１・１’の容積を確保しつつ胴部12の上側部位12bを開口部の受け口として利用できる。
[2-3] Shape of the Body With regard to the shape of the body 12 of the above-mentioned portioned container body 1.1', in this embodiment, as shown in Figures 2(a)(b) and 4(a)(b), the lower portion 12a is formed so that the gradient α is within the range of 5 degrees to 20 degrees, and the upper portion 12b is formed so that the gradient β is within the range of 20 degrees to 50 degrees. Furthermore, the vertical ratio of the lower portion 12a to the upper portion 12b in the overall height of the body 12 is set to be within the range of 6:1 to 2:1. This allows the upper portion 12b of the body 12 to be used as a receptacle for the opening while ensuring the volume of the portioned container body 1.1'.
[2-4]垂下部の形状
上記小分容器本体１・１’の垂下部13の形状に関しては、本実施形態では図２(a)(b)及び図４(a)(b)に示すように垂下部13が外側に向けて外側に広がったテーパ状に形成して垂下部13に対して内側方向の力が加わった場合でも変形が抑えられる。またこの垂下部13のテーパ形状に関しては、図５(a)に示すように勾配γが胴部12の勾配よりも小さくなるように形成することにより小分容器本体１・１’のサイズ(平面視における面積)が大きくなり過ぎないようにしている。また本実施形態では、垂下部13を胴部12の上側部位12aの上下高さの範囲内で形成している。
[2-4] Shape of the Hanging Part In this embodiment, the hanging part 13 of the above-mentioned small-portion container body 1.1' is formed in a tapered shape that widens outward as shown in Figures 2(a)(b) and 4(a)(b), so that deformation is suppressed even when an inward force is applied to the hanging part 13. In addition, the tapered shape of the hanging part 13 is formed so that the gradient γ is smaller than the gradient of the body part 12 as shown in Figure 5(a), so that the size (area in a plan view) of the small-portion container body 1.1' is not too large. In this embodiment, the hanging part 13 is formed within the range of the vertical height of the upper part 12a of the body part 12.
[2-5]フランジ部の形状
上記小分容器本体１・１’のフランジ部14の形状に関しては、本実施形態では図２(a)(b)、図４(a)(b)及び図５(a)に示すように垂下部13の下端から外側に向けて水平方向(真横方向)に張り出した形状となっている。また本実施形態では、フランジ部14の出幅を1.0mm～3.0mmの範囲内で形成することにより、小分容器本体１・１’のサイズ(平面視における面積)が大きくなり過ぎないようにしている。なおフランジ部14の出幅を1.0mm未満とする場合、隣り合う小分容器本体１・１’の重なり合う面積が小さくなり過ぎて容器間の隙間、浮き上がりが生じ易くなる
[2-5] Shape of the flange portion With regard to the shape of the flange portion 14 of the above-mentioned small portion container body 1.1', in this embodiment, it is a shape that protrudes horizontally (straight across) outward from the lower end of the hanging portion 13, as shown in Figures 2(a)(b), 4(a)(b), and 5(a). Also, in this embodiment, the protruding width of the flange portion 14 is formed within the range of 1.0 mm to 3.0 mm, thereby preventing the size (area in a plan view) of the small portion container body 1.1' from becoming too large. Note that if the protruding width of the flange portion 14 is less than 1.0 mm, the overlapping area of adjacent small portion container bodies 1.1' becomes too small, making it easier for gaps and floating to occur between the containers.
また上記フランジ部14は、小分容器本体１・１’を外箱２に敷き詰めた状態で、図５(b)に示すようにフランジ部14・14同士が上下に重なった状態となり、上側のフランジ部14が隣の小分容器本体１’の垂下部13に当接した状態となる。そのため、小分容器本体１・１’に食品を入れたとき、上側のフランジ部14が下側のフランジ部14を抑えつけた状態となる。また食品を収容した食品容器セットＳを持ち運ぶ際、振動や傾きで横方向の力が加わり隣接する小分容器本体１・１’同士が押し合う状態となるが、フランジ部14が垂下部の下端に当接していることで、押し合う力を垂下部13で吸収して小分容器本体１・１の変形を防止できる。 When the portion container bodies 1, 1' are laid out in the outer box 2, the flange portions 14 are stacked vertically as shown in FIG. 5(b), with the upper flange portion 14 abutting the hanging portion 13 of the adjacent portion container body 1'. Therefore, when food is placed in the portion container body 1, 1', the upper flange portion 14 presses down the lower flange portion 14. When carrying the food container set S containing food, a lateral force is applied due to vibration or tilt, causing the adjacent portion container bodies 1, 1' to push against each other, but because the flange portion 14 abuts against the lower end of the hanging portion, the pushing force is absorbed by the hanging portion 13, preventing deformation of the portion container body 1, 1.
また図５(b)に示すようにフランジ部14・14同士が重なり合うことで、小分容器本体１・１’同士の間に隙間が生じないため、食品容器セットＳを上側から見たとき、小分容器本体１・１’の隙間から外箱２の底面が見えることがなく、食品容器セットＳの外観を改善できる。また小分容器本体１・１’同士の間に隙間が生じないことで、外箱２の底面に食品が落ち込んだり液漏れしたりする問題も防止できる。 In addition, as shown in Figure 5(b), by overlapping the flanges 14, 14, no gaps are created between the portioned container bodies 1, 1', so when the food container set S is viewed from above, the bottom of the outer box 2 cannot be seen through the gaps between the portioned container bodies 1, 1', improving the appearance of the food container set S. In addition, by eliminating gaps between the portioned container bodies 1, 1', problems such as food falling onto the bottom of the outer box 2 or liquid leaking can be prevented.
[2-6]仕切部を備えた変更例
本実施形態では、小分容器本体１・１’に仕切部を設けない形状を採用しているが、小分容器本体１・１’の内側に長さ方向、幅方向または対角線方向の仕切部を一体または別体で設けることもでき(図示せず)、その場合には、小分容器本体１・１’の数以上の種類の食品を食品容器セットＳに収容することができる。
[2-6] Modification with a partition In this embodiment, a shape is adopted in which the small-portion container body 1.1' does not have a partition, but a partition in the lengthwise, widthwise or diagonal direction can be provided integrally or separately on the inside of the small-portion container body 1.1' (not shown), in which case more types of food can be stored in the food container set S than the number of small-portion container bodies 1.1'.
[2-7]蓋部材を備えた変更例
本実施形態では、小分容器本体１・１’を蓋なしの形状としているが、小分容器本体１・１’に蓋部材を別体または一体に設けることもでき(図示せず)、その場合には、小分容器本体１・１’に水分が多い食品や液状のタレで味付けした食品を収容する場合でも小分容器本体１・１’からの液漏れを防ぐことができる。
[2-7] Modification with a lid member In this embodiment, the portion container body 1.1' is shaped without a lid, but a lid member can be provided separately or integrally with the portion container body 1.1' (not shown). In that case, leakage of liquid from the portion container body 1.1' can be prevented even when the portion container body 1.1' contains foods with a high moisture content or foods seasoned with a liquid sauce.
[2-8]受け台を備えた変更例
本実施形態では、小分容器本体１・１’を全て同じ高さに形成しているが、異なる高さのもの(例えば、醤油等を入れるための底が浅いもの)を使用することもできる。その場合、高さが小さい小分容器本体１を載せる受け台を別体または一体に設けて、高さが大きい小分容器本体１の上面に合わせることもできる(図示せず)。
[2-8] Modification with a pedestal In this embodiment, the small portion container bodies 1, 1' are all formed to the same height, but those of different heights (for example, those with a shallow bottom for putting soy sauce, etc.) can also be used. In that case, a pedestal for placing the small portion container body 1 with a smaller height can be provided separately or integrally, and can be aligned with the upper surface of the large portion container body 1 (not shown).

[3] About the outer box
[3-1] Material and shape of outer box With regard to the material of the outer box 2, in this embodiment, a box body made of a plastic material is used, but wood materials (paulownia wood box) and metal materials other than plastic materials can also be used as long as they are more rigid than the small-portion container body 1. With regard to the shape of the outer box 2, a folding box or a stacked box can be appropriately adopted depending on the purpose of the food container set S (New Year's feast, a cherry blossom viewing lunch box, a train station lunch box, etc.). The shape of the outer box 2 in a plan view is preferably polygonal, and in particular, is preferably rectangular or octagonal (e.g., an octagonal stacked box).
