Abstract
A high pressure gas container hermetically confining therein a high pressure gas for inflating instantaneously a safety air bag to protect occupants in a vehicle is provided with an improved discharge valve for blowing out the gas from the container. The discharge valve comprises a sealing disk disposed at a blocking cock portion, which disk has a thick center portion and thin peripheral portion so that the whole disk may be utterly ruptured upon explosion of a detonator disposed adjacent to the thicker portion of the sealing disk. Such complete destruction of the sealing disk will result in a formation of a large opening for blowing out the high pressure gas and hence allows a rapid inflation of the safety air bag due to increased flow rate of the jetted high pressure gas from the container.
