<p>A breakable safety valve installed to a metal-made container so as to add an explosion-proof function to the container. This valve is installed to a small-sized battery container, etc. When the internal pressure of the container abnormally rises due to overcharging etc., and reaches a specific value, the pressure is quickly released so as to prevent the danger to human bodies or damages to devices and machines caused by the blasting or deformation of the container, while the valve maintains the sealing of the container. The metal foil safety valve is manufactured by cold-welding metal foil to a metal-made container so as to block the vent hole of the container. When the internal pressure of the container reaches the specific value, the metal foil breaks, an opening is made in the container, and the internal pressure of the container is released.</p> |
