    • The present invention herein provides an oxygen-absorbing resin composition which is excellent in the oxygen-absorbability and which can inhibit any deterioration through oxidation during the molding operations of the composition and does not accordingly undergo any coloration during the molding operations. The present invention thus provides an oxygen-absorbing resin composition characterized in that it comprises (A) a hydrogenated styrene-diene copolymer; (B) a thermoplastic resin including ethylenic structural units in its molecular structure; and (C) a transition metal catalyst, wherein the oxidation of the thermoplastic resin (B) proceeds while the copolymer (A) serves as a trigger and the composition thus absorbs oxygen. In this respect, the copolymer (A) comprises carbon-carbon double bonds derived from the diene in an amount ranging from 1×10.5 to 1×10.2 eq/g.

    • A thickness-reduced deep-draw-formed can obtained by using, as the substrate, a cold-rolled steel plate having a carbon content in the steel of 0.02 to 0.15% by weight, a manganese content in the steel of 0.2 to 1.0% by weight, a mean diameter of crystal grain of smaller than 6.0 .mu.m, a tensile strength over a range of from 35 to 55 kg/mm.sup.2, and a thickness of 0.17 to 0.30 mm in a step of subjecting an organic resin-coated structure of the surface-treated steel plate to the thickness-reducing deep-draw forming. This makes it possible to suppress the generation and accumulation of heat in the organic resin-coated steel plate to a level lower than the conventional levels. Therefore, the organic resin coating is prevented from being peeled off or damaged and, as a result, the corrosion resistance can be markedly improved. Moreover, wrinkles can be effectively prevented from developing at the time of reducing the thickness, and the forming can be continuously carried out at a high speed without being substantially affected by the generation or accumulation of heat. It is further possible to easily carry out the post treatments such as necking, flanging and multi-beading after the forming. The thickness-reduced deep-draw-formed can of the invention is effective particularly for preserving various kinds of juices, coffee, oolong tea and any other beverages after it is hermetically sealed, retort-sterilized and reduced for its internal pressure.
    • 使用钢中碳含量为0.02〜0.15重量%,钢中的锰含量为0.2〜1.0%的冷轧钢板作为基材,可以得到厚度减薄的深拉成形物, ,在有机树脂被覆结构体的工序中,平均粒径小于6.0μm,拉伸强度为35〜55kg / mm 2,厚度为0.17〜0.30mm 的表面处理钢板进行厚度减薄深拉成形。 这使得可以将有机树脂涂覆钢板中的热的产生和积聚抑制到低于常规水平的水平。 因此,防止有机树脂涂层被剥离或损坏,结果可以显着提高耐腐蚀性。 此外,在减小厚度的同时可以有效地防止褶皱的发展,并且可以高速连续地进行成形,而不会受到热的产生或积累的显着影响。 还可以容易地进行后处理,例如成型后的颈缩,翻边和多重着色。 本发明的厚度减薄的深拉制罐尤其适用于在气密密封,蒸煮灭菌和内压降低后保存各种果汁,咖啡,乌龙茶和任何其他饮料。
