摘要： An easy opening can end is provided whose can end panel is made of steel sheet having both sides coated with resin layers which each include at least one type of thermoplastic resin and which have elongation after break of 100% or more, tensile strength of 10 kg/mm2 or more, Young modulus of 100 kg/mm2 or more and a thickness in range of 10 to 100 &mgr;m. A score is formed on at least one of a front or a back side of the can end panel so as to be capable of breakage for opening the can end. The score has a bottom cross-section in a shape of an arc having a radius in a range of 0.10 to 1.0 mm, and a thinnest section of the score has a thickness t in a range of 0.025 to 0.080 mm. The easy opening can end has no problem of resin layer damage when the score is formed and has excellent can openability to such an extent that children and the aged may easily open the can end, so that the easy opening can end is most suitable for a can end of a beverage can and a food can.
摘要翻译：提供容易的开口端，其端面板由两面涂有树脂层的钢板制成，每个树脂层各自包括至少一种热塑性树脂，断裂伸长率为100％以上，拉伸强度为10kg / mm 2以上，杨氏模量为100kg / mm 2以上，厚度为10〜100μm的范围。在罐端板的前侧或后侧中的至少一个处形成刻痕，以便能够破坏罐端部的开口。得分具有半径在0.10至1.0mm范围内的圆弧形状的底部横截面，得分的最薄部分的厚度t在0.025至0.080mm的范围内。容易开口可以结束，当分数形成时没有树脂层损伤的问题，并且具有优异的可开放性，使得儿童和老年人可以容易地打开罐端，使得容易开口可以结束最适合于可以结束饮料罐和食物罐。

摘要： This invention is intended for providing a soft magnetic steel material having excellent DC magnetization properties and corrosion resistance, and capable of being manufactured at a low cost, and a method of manufacturing the same.The soft magnetic steel material of this invention contains 0.8 to 3.5% by weight of soluble aluminum, as well as limited amounts of C, total nitrogen, Si, Mn, P, S and total oxygen, and has an average ferrite crystal diameter of which the minimum has a specific relation to the thickness or diameter of the material. The material has a surface covered densely with aluminum oxide particles having a diameter of 0.01 to 5 microns. It exhibits a coercive force not exceeding 0.4 Oe in the absence of any strain and a magnetic flux density of 15,000 G or more at a magnetomotive force of 25 Oe. The aluminum oxide particles formed on the surface of the material are preferably formed with a density of 1.times.10.sup.12 to 1.times.10.sup.16 particles, or more preferably 1.times.10.sup.13 to 1.times.10.sup.16 particles, per square meter to achieve its excellent corrosion resistance.The material is manufactured by the final heat treatment of a steel material having the composition stated above at a temperature of 850.degree. C. to 1300.degree. C. in an atmosphere having an oxygen partial pressure of 10.sup.-6 to 10.sup.-2 preferably 10.sup.-6 to 10.sup.-3 or more preferably 10.sup.-5 to 10.sup.-3 atmosphere.
