る。In the tray shown in FIG. 1, a corrugated cardboard sheet is drawn to form a pair of side walls 2 and an end wall 3 around a bottom wall 1, and a flange 4 is formed on the peripheral portion of the bottom wall to form a bottom. A rib 5 is provided on the wall 1 so as to intersect the step.
【０００９】この成形に際しては、まず、材料となる段
ボールシートを打ち抜いて、図２に示すようなブランク

時の押圧や、軽い絞り加工により形成する。なお、補助
押部７として罫線を入れてもよい。In this molding, first, a corrugated cardboard sheet as a material is punched out to form a blank 6 as shown in FIG. The blank 6 is formed with an auxiliary pushing portion 7 at a position corresponding to the rib 5. The auxiliary pressing portion 7 is formed by pressing at the time of punching or light drawing. A ruled line may be provided as the auxiliary pushing portion 7.
【００１０】次に、図３に示すように、ブランク６を下
型８と上型９の間に挟んで、加熱プレスすると、補助押
部７の部分がさらに押し出され、図１に示すように、底
壁１にリブ５を備えたトレーが形成される。Next, as shown in FIG. 3, when the blank 6 is sandwiched between the lower mold 8 and the upper mold 9 and heated and pressed, the auxiliary pressing portion 7 is further pushed out, and as shown in FIG. A tray having ribs 5 on the bottom wall 1 is formed.
【００１１】このように、ブランク６に予め補助押部７
を形成しておくと、その部分が容易に押し出され、リブ
５が無理なく形成される。In this way, the blank 6 is previously provided with the auxiliary pushing portion 7
When the rib is formed, that portion is easily extruded, and the rib 5 is formed without difficulty.
【００１２】そして、このように成形したトレーは、段
ボールシートの折れ曲がりやすい方向がリブ５で補強さ
れるので、例えば、一方の側壁２を掴んで持ち上げて
も、底壁１が変形しにくいものとなる。In the thus-formed tray, the direction in which the corrugated cardboard sheet is easily bent is reinforced by the ribs 5, so that even if one side wall 2 is gripped and lifted, the bottom wall 1 is unlikely to be deformed. Become.
【００１３】なお、リブ５は、段目に対し３０°〜９０
°の角度で設けるのがよい。また、底壁１だけでなく、
側壁２にリブ５を設けるようにしてもよい。The rib 5 has a step angle of 30 ° to 90 °.
It is better to set it at an angle of °. In addition to the bottom wall 1,
A rib 5 may be provided on the side wall 2.
【００１４】ここで、図４に示すように、補助押部７の

ブ５の高さｈ2及び幅ｄ2を設定すれば、段ボールシート
の破断を生じることなくリブ５を形成できる。Here, as shown in FIG. 4, the height h 1 of the auxiliary pushing portion 7 is set to 1 to 20 times the thickness t of the corrugated board sheet, and the width d 1 is set to 1 time or more the height h 1 . If the height h 2 and the width d 2 of the rib 5 are set so that the width becomes 0.2 to 1 times and the height becomes 1 to 50 times with the drawing process, the corrugated board sheet is broken. Without forming the rib 5.
