    • PROBLEM TO BE SOLVED: To provide a can container equipped with an easily breakable part which is surely broken to vent inner gas when the inner pressure in the can is abnormally elevated, and has no possibility of breaking on other cases. SOLUTION: The easily breakable part 5 which is to be broken when the inner pressure of the can container is abnormally elevated and a dome part 3A is deformed so as to project to the outside of the can container, is formed on the outer face side of the dome part 3A just closely positioned at the outer peripheral edge part 3C of the dome part 3A continuous to a caulking part 3D. For example, when the inner pressure of the can container is abnormally elevated by heating or the like, and the dome part is turned reversely by the outer peripheral edge part of the dome part of a bottom lid as a base point and it is deformed so as to be projected outside of the can container, as the easily breakable part is broken to discharge a content in the can container, even if the inner pressure is abnormally elevated, there exists no possibility of blowing off a part of the can container and the gas can be vented.

    • 要解决的问题:提供一种罐容器,该容器装有容易断裂的部件,当容器内部的内部压力异常升高时,该容器可靠地断裂以排出内部气体,并且在其他情况下不可能发生破裂。 解决方案:当容器容器的内部压力异常升高并且圆顶部分3A变形以便突出到容器容器的外部时将被破坏的容易断裂部分5形成在外部 穹顶部3A的正面紧贴在与铆接部3D连续的圆顶部3A的外周缘部3C处。 例如,当罐式容器的内部压力通过加热等异常升高时,通过底盖的圆顶部的外周缘部作为基点而使穹顶部反向转动并变形为 为了突出到容器容器的外部,即使容易破损的部分被破坏,从而排出罐容器中的内容物,即使内部压力异常升高,也不可能吹出罐头容器的一部分, 气体可以排出。 版权所有(C)2006,JPO&NCIPI
