Abstract A method for quickly releasing fluid from a container adapted to contain high pressure fluid which includes a frangible diaphragm. The method utilizes a pressure release mechanism which includes a guide removably attached to the outside of the container adjacent the diaphragm for guiding a sharpened member into piercing engagement with an edge portion of the diaphragm under the urging of a spring whence the diaphragm bends about its remaining edge portion to allow egress of fluid from the container. The spring can be held in cocked position by means of a movable tapered pin in which position it applied no force to the sharpened member and this pin may be released manually or by other means to allow rupture of said diaphragm. The spring may also be housed in a separate housing along with a metal slug while the cutter may be mounted within a cap adjacent to the diaphragm with its piercing edge engaging the diaphragm. The spring may then be released to drive the slug into the cutter which, in turn, pierces the diaphragm.
A method for quickly releasing fluid under high pressure from a container thereof through an aperture having a diaphragm covering the aperture and sealed around its periphery to the container, said method comprising urging a pointed piercing means through the diaphragm at a location immediately adjacent the periphery of the aperture to form a flap having a free edge portion and an opposite supported portion which is integral with the remainder of the flap; and ripping out the flap from the sealed circumferential edge supported portion of the diaphragm by means of the pressure of the fluid in the container acting againsT the flap and creating a moment of force which bends the flap about its remaining supported portion.
