摘要： A can container having a screw where a joint step of a joined can barrel is formed, wherein opening torque of the cap of the container is reduced. The can container has a hollow cylindrical container body section with an overlap joint (16) on a side face of which the step (15) is formed, and also has a container mouth portion (5) with a screw thread and a curl portion that are formed at the opening end of the container body section. A bottom lid is tightly wound around the lower end of the body section, the cap having a resin sealing liner attached to the inner surface side at the top plate portion of the cap is put on the container opening, and the cap is tightly wound around the container mouth portion to form a screw groove in a skirt portion of the cap so as to match the screw thread. The screw thread is formed, relative to the joint (16), from the upper side to lower side of the overlapped step, in the direction where the cap (7) is opened.

摘要： To ensure sealing ability of a resealable can container formed of a welded can body between a curled portion of container mouth and a resin sealing liner, without degrading productivity and easiness to open the closure.
The can body 2 is prepared by rolling a steel sheet and welding overlapped longitudinal edges of the steel sheet. In order to achieve the above-mentioned objective, a level difference of a welded portion 2a on the surface of a curled portion 21a is reduced smaller than that on the trunk portion 22, specifically, kept within the range of 15 to 100 µm, and a durometer hardness of the resin sealing liner is kept within the range of HDA 30 to 70 according to ISO 868 (or JIS-K7215).摘要翻译： 为了确保在容器口部的卷边部与树脂密封衬垫之间由焊接罐体形成的可再密封罐容器的密封性，而不降低生产率并容易打开封闭件。 罐体2通过轧制钢板并焊接钢板的重叠纵向边缘来制备。 为了实现上述目的，卷曲部分21a的表面上的焊接部分2a的水平差比主体部分22上的水平差小，特别是保持在15至100μm的范围内，以及 根据ISO 868（或JIS-K7215），树脂密封衬里的硬度计硬度保持在HDA 30至70的范围内。

摘要： To reduce a torque to open a closure of a can container having a step of a lap side seam on a thread.
A threaded can container of the invention comprises: a cylindrical can body having a lap side seam 16 where longitudinal edges of a metal sheet forms a step portion; a container mouth 5 formed on an opening end of the can body where a thread ridge and a curled portion are formed thereon; a bottom lid seamed to a lower end of the can body; and a resealable closure, which is applied to the container mouth, and which has a resin sealing liner affixed to an inner face of a top panel thereof, and a thread groove rolled on a skirt portion thereof in conformity with the thread ridge; wherein the thread ridge is formed to rotate the closure in a direction from an outer edge of the lap side seam toward an inner layer of the lap side seam to open the closure.摘要翻译： 为了减少打开具有在线上的搭接侧接缝的步骤的罐容器的封闭的扭矩。 本发明的螺纹罐容器包括：圆筒形罐体，其具有搭接侧接缝16，金属片的纵向边缘形成台阶部分; 形成在罐主体的开口端上的容器口5，其上形成有螺纹脊和卷曲部分; 底盖接合到罐体的下端; 以及适用于容器口部的可再密封的封闭件，其具有固定在其顶板的内面上的树脂密封衬垫和在其与裙边部分一致的螺纹槽; 其中，所述螺纹脊形成为使所述封闭件沿着所述搭接侧接缝的外边缘朝向所述搭接侧接缝的内层的方向旋转以打开所述封闭件。
