    • A closed battery container having walls defining an interior which is subjected to one of a first and a second pressure, the first pressure much lower than the second pressure. The closed container includes a highly rigid panel at least partially forming one of the container walls, the panel having an interior surface exposed to the interior of the container, and an opposite, exterior surface. One of the interior and exterior panel surfaces is provided with a groove having substantially parallel first and second groove segments, the first and second groove segments laterally spaced, and a third groove segment extending between the first and second groove segments. The panel has a first portion which lies on one side of the third groove segment, and a second portion which lies on the opposite side of the third groove segment, the first and second panel portions integrally connected across the third groove segment at the first container interior pressure, whereby the panel is in an unruptured state. The first and second panel portions are integrally disconnected across the third groove segment in response to the container interior being at the second container interior pressure, whereby the panel is in a ruptured state.
    • 一种封闭的电池容器,其具有限定内部的壁,所述内部经受第一和第二压力之一,所述第一压力远低于所述第二压力。 密封容器包括至少部分地形成容器壁之一的高度刚性的面板,该面板具有暴露于容器内部的内表面和相对的外表面。 内部和外部面板表面中的一个设置有具有基本上平行的第一和第二凹槽部分的凹槽,第一和第二凹槽部分横向隔开,以及在第一和第二凹槽部分之间延伸的第三凹槽部分。 面板具有位于第三槽段一侧的第一部分和位于第三槽段相对侧上的第二部分,第一和第二面板部分在第一容器 内部压力,由此面板处于未破裂的状态。 响应于容器内部处于第二容器内部压力,第一和第二面板部分跨越第三凹槽段整体断开,由此面板处于破裂状态。
