摘要： A can container, wherein an easily breakable part broken when an internal pressure in the can container abnormally rises and the can container is deformed so that a dome part is projected to the outside of the can container is formed on the outer surface side of the dome part positioned just near the outer peripheral edge part of the dome part continued to caulking parts. For example, when the internal pressure in the can container is abnormally raised by heating, and the dome part is inverted from the outer peripheral edge part of the dome part of a bottom cover and deformed so as to be projected to the outside of the can container, the easily breakable part is broken, and the contents in the can container is released from the can container. Thus, even if the internal pressure abnormally rises, degassing can be performed without allowing a part of the can container to be blown off.

摘要： An easily rupturable portion, which is ruptured when an inner pressure of a can container is raised extraordinary and the domed portion is thereby deformed to protrude outwardly of the can container, is formed on an outer face side of the domed portion and situated in the close vicinity of an outer circumferential portion of the domed portion continuing into a seamed portion. For example, the easily rupturable portion is ruptured to release the contents of the can container when an inner pressure of a can container is raised extraordinary by heat or the like to deform the domed portion of a bottom lid to protrude outwardly within the outer circumferential portion of the domed portion. Therefore, a gas can be released without blowing off a portion of the can container
摘要翻译： 当罐形容器的内部压力异常升高并且圆顶部分由此变形为向罐形容器的外部突出时，破裂的易破裂部分形成在穹顶形部分的外表面侧上并且位于靠近 该圆顶部分的外周部分的附近延续到接缝部分中。 例如，当通过加热等使罐容器的内部压力异常升高以使底盖的圆顶部分变形以在外周部分内向外突出时，易破裂部分破裂以释放罐容器的内容物 的圆顶部分。 因此，可以释放气体而不会吹掉罐容器的一部分
