PROBLEM TO BE SOLVED: To facilitate assembly and article storing work, prevent unlocking of locks for shape retention and secure an effect of preventing piling deviation.SOLUTION: In a cardboard-made tray, a side wall 2 and an end wall 3 are provided around a bottom wall 1 with a corner part between them, and the double end wall 3 and a retaining wall 7 connected to the side end of the end wall 3 are bent by folding in a mutually rolled state. The end of the side wall 2 is sandwiched with retaining plates 8 and 9 of the retaining wall 7 to keep a standing state of the side wall 2 and the end wall 3. An insertion piece 14 provided in the lower part, on the tip side, of the outer retaining plate 8 through a bent part 16 is inserted into an insertion hole 15 provided in a ridge part between the bottom wall 1 and the side wall 2 to lock. The engagement edge 15a of the insertion hole 15 is inclined in the direction in which the end wall 3 side rises, relative to the end side of the bottom wall 1 which is to become horizontal in an assembled state. To prevent piling deviation, a part between two crease lines 16b and 16c of the bent part 16 is folded obliquely relative to the insertion piece 14. 【課題】組立及び物品収納作業の容易化を図ると共に、保形用ロックの外れを防止し、また、積みずれ防止効果が確実に得られるようにする。【解決手段】底壁１の周囲にコーナー部を挟んで側壁２及び端壁３を連設し、二重の端壁３とその側端に繋がる抱持壁７とを共に巻き込むように折り曲げて屈曲させ、抱持壁７の抱板８，９の間に側壁２の端部を挟み込んで、側壁２及び端壁３の起立状態を維持する厚紙製トレイにおいて、外側の抱板８の先端側下部に折曲部１６を介して設けた差込片１４を、底壁１と側壁２の稜部に設けた差込穴１５に差し込んでロックするものとし、差込穴１５の係止縁１５ａを、組立状態で水平となる底壁１の端辺に対して、端壁３側が上がる方向へ傾斜させる。積みずれ防止のため、折曲部１６の２本の折目線１６ｂ、１６ｃに挟まれた部分が差込片１４に対して斜めに折れ曲がるようにする。【選択図】図３
