Description

本発明は、固形食品用包装容器、さらに詳しくは、カレールウ、シチュールウ等の固形食品を溶融状態で注ぎ込み、冷却固化した状態で物流等に供する固形食品用包装容器に関する。   The present invention relates to a solid food packaging container, and more particularly to a solid food packaging container in which solid food such as curry roux and stew is poured in a melted state and cooled and solidified for distribution.

固形食品用包装容器は、カレールウやシチュールウ等の固形ルウに代表される固形食品用の容器である。容器入り固形ルウの製造方法は、例えば次の二つの方法が実施されている。第１は、加熱調理されたルウを固形食品用包装容器に充填し密封した後、冷却して固形化する方法である。第２は、加熱調理したルウを固形食品用包装容器に充填した後、冷却して固形化し、その後に蓋をして密封する方法である。   The solid food packaging container is a container for solid food represented by solid roux such as curry roux and stew roux. For example, the following two methods are carried out as a method for producing the solid roux contained in the container. The first is a method in which heat-cooked roux is filled in a solid food packaging container and sealed, and then cooled and solidified. The second is a method of filling cooked roux into a solid food packaging container, cooling and solidifying, and then sealing with a lid.

このような固形食品用包装容器に充填された固形ルウを使用する場合、調理時のルウの溶解性を良くする目的で、適当な大きさにルウを容易に割ることができるように、固形ルウの底面等にクビレすなわち溝状凹みを形成している。この溝状凹みを形成するために、固形食品用包装容器の底部に稜線凸部を形成している。   When using solid roux filled in such a solid food packaging container, solid roux can be easily divided into appropriate sizes for the purpose of improving the solubility of roux during cooking. Constrictions, that is, groove-shaped recesses are formed on the bottom surface of the plate. In order to form this groove-shaped dent, a ridge line convex portion is formed at the bottom of the solid food packaging container.

固形食品用包装容器の成形材料としては、ポリエチレンテレフタレート、ポリカーボネート、ポリプロピレン等の合成樹脂の単層シート、ポリプロピレン／エチレン−ビニルアルコール共重合体／ポリプロピレン等の合成樹脂製多層シートが使用されている。これらの成形材料は、真空成形あるいは圧空成形等によって成形される。   As a molding material for a solid food packaging container, a single-layer sheet of a synthetic resin such as polyethylene terephthalate, polycarbonate, or polypropylene, or a multilayer sheet made of a synthetic resin such as polypropylene / ethylene-vinyl alcohol copolymer / polypropylene is used. These molding materials are molded by vacuum molding or pressure molding.

従来の固形食品用包装容器の形状として、全周囲部のほぼ全域を実質上同一高さとし、内部に少なくとも２個の大凹部を設け、該大凹部内が複数の小凹部に分割されている、薄板製の固形食品用容器において、上記大凹部の境界部が、上記全周囲部から下降し、上記２個の大凹部の略中心を結ぶ線と平行な斜面部を有することを特徴とする固形食品用容器が提案されている（例えば、特許文献１参照）。
また、他の固形食品用包装容器の形状として、容器の底部を、長手方向と直交する幅方向の中心に長手方向に延びた長手方向稜線を一本設け、長手方向を３等分するように幅方向に延びた幅方向稜線を２本設け、さらに、底部形状を前記両稜線によって区切られた区画をかまぼこ状にしたものが提案されている（例えば、特許文献２参照）。 As the shape of the conventional solid food packaging container, the substantially entire area of the entire peripheral portion is substantially the same height, at least two large recesses are provided inside, the inside of the large recess is divided into a plurality of small recesses, A solid food container made of a thin plate, wherein a boundary portion of the large concave portion has a slope portion that descends from the entire peripheral portion and is parallel to a line connecting substantially the centers of the two large concave portions. Food containers have been proposed (see, for example, Patent Document 1).
As another shape of the solid food packaging container, the bottom of the container is provided with one longitudinal ridge line extending in the longitudinal direction at the center in the width direction orthogonal to the longitudinal direction, and the longitudinal direction is divided into three equal parts. Two widthwise ridgelines extending in the widthwise direction are provided, and the bottom portion of the section divided by the two ridgelines is shaped like a semi-cylindrical shape (see, for example, Patent Document 2).

特許文献２の固形食品用包装容器を、厚さ２８０μｍの上記合成樹脂製多層シートによって形成して、実験した結果は以下のとおりである。固形食品用包装容器１１０は、図６に示すように、水平に延びた長手稜線１０２が、緩やかな角度で上広がりに傾斜した幅側面１０４に突き当たるように形成されている。そのため、突き当たり領域１０６は、形状的に極端な薄肉部が生じ易い部位であり、上記突き当たり領域１０６の最小厚みを測定すると、
平均厚さ７９．３μｍ
最小厚さ６０μｍ
標準偏差９．０
であった。この厚さの樹脂シートを使用する場合は、突き当たり領域１０６において、成形時の穴あき等の成型不良が発生することはなく、製品として使用可能である。また、落下試験においても固形食品用包装容器の微小な破れは発生しなかった。引用文献１に記載された固形食品用包装容器についても、容器形状が異なれば、厚みも異なってくるが、成形性や落下試験において、ほぼ同一の結果になるものと推定される。固形食品用包装容器１１０に充填されたカレールウの割れ容易性は良好であった。 The experiment result of forming the packaging container for solid food of Patent Document 2 with the above-mentioned synthetic resin multilayer sheet having a thickness of 280 μm is as follows. As shown in FIG. 6, the solid food packaging container 110 is formed such that a horizontally extending longitudinal ridgeline 102 abuts against a wide side surface 104 inclined upwardly at a gentle angle. Therefore, the contact area 106 is a part where an extremely thin portion is easily formed in shape, and when the minimum thickness of the contact area 106 is measured,
Average thickness 79.3μm
Minimum thickness 60μm
Standard deviation 9.0
Met. When a resin sheet having this thickness is used, in the abutting region 106, there is no occurrence of molding defects such as perforation during molding, and the product can be used as a product. In the drop test, the solid food packaging container did not break. Regarding the solid food packaging container described in Cited Document 1, if the container shape is different, the thickness is also different, but it is presumed that almost the same result is obtained in the moldability and drop test. The ease of cracking of curry roux filled in the solid food packaging container 110 was good.

前記落下実験は、固形食品用包装容器の物流状況を想定し、カレールウを充填した固形食品用包装容器１２０個を紙箱に入れ、さらに段ボール箱に梱包し、それを５°Ｃに調温した冷蔵環境で２４時間以上保管した。その後、冷蔵した前記段ボール箱を、高さ３５ｃｍより落下させた。落下させた方向は、前記ダンボール箱の６面を各々下面すなわち衝突面とする落下方向の落下、及び正立落下すなわち前記段ボール箱の天地面を正しい向きにした状態で落下を行い、合計７回の落下試験を行った。その後、固形食品用包装容器の微小な破れの有無等を検査するものである。   In the drop experiment, assuming the physical distribution of solid food packaging containers, 120 solid food packaging containers filled with curry roux are placed in a paper box, further packed in a cardboard box, and refrigerated at 5 ° C. Stored in the environment for more than 24 hours. Thereafter, the refrigerated cardboard box was dropped from a height of 35 cm. The dropped direction is a drop in the drop direction with each of the six surfaces of the cardboard box as a lower surface, that is, a collision surface, and an upright drop, that is, with the top and bottom of the corrugated cardboard box in the correct orientation. A drop test was conducted. Then, the presence or absence of minute tearing of the solid food packaging container is inspected.

樹脂シートの使用量を削減するため、厚さ２４０μｍの前記合成樹脂製多層シートによって成形して、前記実験とまったく同一の実験を行った。
固形食品用包装容器１１０の突き当たり領域１０６は、形状的に極端な薄肉部が生じ易い部位であり、上記突き当たり領域１０６の最小厚みを測定すると、
平均厚さ７３．４μｍ
最小厚さ４５μｍ
標準偏差９．３
であった。この厚さ２４０μｍの合成樹脂製多層シートを使用した場合、成形時に突き当たり領域１０６において穴あき等の成型不良が発生しなかった。しかし、落下試験においては固形食品用包装容器の突き当たり領域１０６に微小な破れが発生した。固形食品用包装容器１１０に充填されたカレールウの割れ容易性は良好であった。 In order to reduce the amount of the resin sheet used, the same experiment as the above experiment was performed by molding with the synthetic resin multilayer sheet having a thickness of 240 μm.
The abutting area 106 of the solid food packaging container 110 is a part where an extremely thin portion is easily formed in shape, and when the minimum thickness of the abutting area 106 is measured,
Average thickness 73.4μm
Minimum thickness 45μm
Standard deviation 9.3
Met. When this synthetic resin multilayer sheet having a thickness of 240 μm was used, molding defects such as perforations did not occur in the abutting region 106 during molding. However, in the drop test, a minute tear occurred in the abutting area 106 of the solid food packaging container. The ease of cracking of curry roux filled in the solid food packaging container 110 was good.

上記問題点を解決する方法として、容器形状の角や稜線が丸みを帯びた形状にする方法がある。この方法を用いて樹脂量の削減を行うと、成形時に極端な薄肉部が生じるのを避けるために、容器形状の角や稜線の丸みを、より緩やかにする必要があり、容器の内側にさらに入り込むような容器形状となり、容器容量が減少することになる。その結果、同じ体積の内容物を充填するためには、より大きな容器が必要になるので、輸送効率の面から好ましくない。さらに、稜線先端の鋭利さが失われることになり、固形食品の割れ容易性が低下することになることも好ましくない。   As a method for solving the above problems, there is a method in which the corners and ridgelines of the container shape are rounded. If this method is used to reduce the amount of resin, it is necessary to make the corners of the container shape and the roundness of the ridge lines more gentle in order to avoid the formation of extremely thin parts during molding. The container shape enters and the container capacity is reduced. As a result, in order to fill the same volume of contents, a larger container is required, which is not preferable in terms of transport efficiency. Furthermore, it is not preferable that the sharpness of the edge of the ridge line is lost, and the ease of cracking of the solid food is reduced.

（発明の目的）
本発明は、従来技術の固形食品用包装容器の上述した問題点に鑑みてなされたものであって、割れ容易性の高い形状で固形食品が収納されており、従来よりも１割以上、樹脂の使用量を削減したポリエチレンテレフタレート、ポリカーボネート、ポリプロピレン等の合成樹脂の単層シート、ポリプロピレン／エチレン−ビニルアルコール共重合体／ポリプロピレン等の合成樹脂製多層シートを使用して成形しても、成形時の穴あき等の成形不良がなく、試験時の微小な破れが発生するおそれもない固形食品用包装容器を提供することを目的とする。 (Object of invention)
