【発明の属する技術分野】
本発明は、弁当箱の蓋体と弁当箱本体の上部と下部に凹と凸の突起を付けて飯の片寄りを無くし、また、密閉したおかず入れ部を一体化して装着したことで持ち運ぶ角度及び状態によらず、飯の片寄りがなく、自由な持ち運びができる弁当箱に関するものである。
【０００２】
【従来の技術】
従来の弁当箱は、横（水平）に持ち運ぶ物で、その幅以上に手を広げて運ぶ物であり手の疲れがひどく、また人通りの多い所では、他人に迷惑を掛けるのを気にして動きにくいので不便である。
そして、弁当箱の持ち運び方によっては、飯が片側に片寄り人前では開けずらく、誰もが苦笑した経験があり、この解決策として考え出されたのが水平２段式弁当箱であるが、持ち広げ幅が半分に成っただけで、飯が片寄る問題は解消されていない。その上、この水平２段式弁当箱は、長方形角型でカバンに入らず外姿が悪く女性や会社員等に嫌われた弁当箱である点がデメリットとして付加された。
次に考え出されたのが、飯に圧力を掛けて該飯を押し固めた弁当箱であるが、食べる時は、該飯が餅風に成り飯の感覚がしない。すなわち、この押し固めた弁当箱の飯は適度の固さ以上となってしまうので飯の感覚がせず、日本古来の主食から掛け離れたものとなっている。したがって、各メーカーは、弁当箱に対して膨大な研究費や試作費をついやして研究したが解決しなかった。
【０００３】
【本発明が解決しょうとする課題】
そこで、本発明は、上記に鑑みてなされたもので、その課題は弁当箱の飯が適度の硬さを保ち、飯の片寄りのない弁当箱を提供することである。付言すると、本発明は弁当を作る人、食べる人達の強い要望に答えることを、課題とするものである。具体的な課題は、以下の通りである。
（イ）持ち運びが縦（垂直）持ち、横（水平）持ち、又は自由な角度で運搬しても弁当箱の飯の片寄りが発生しない事。
（ロ）書物と同様に薄いカバンに収納できる事。
（ハ）弁当箱の特性として、味と味覚を失わずに食欲を誘う弁当箱である事。
（ニ）弁当箱に飯を詰めるのに特別な時間を必要としない事。
（ホ）飯の詰め込み硬さが良好で、美味しい弁当箱の飯である事。
（ヘ）弁当箱の製作者の真心が食する人に伝わる弁当箱である事。
【０００４】
