Abstract
This disclosure relates to a rupture disk (400), which may include a flange portion (401), a reverse-buckling dome portion (403), and a transition portion (402) joining the flange portion to the reverse-buckling dome portion. The dome portion may define an apex. The dome portion may further define an indentation (404) at the apex and/or a line of weakness (405), which may be proximate to the transition portion and/or may include a relatively weak segment configured to initiate rupture. An integral stress concentrating feature may be provided. A line of weakness and/or a base of a domed portion may be non-circular. The disclosure also relates to a rupture disk crimped into a holder (410). The disclosure also relates to a container having a wall that defines a rupturable portion.
Claims23
A rupture disk, comprising:
- a flange portion;
- a reverse-buckling dome portion;
- and
- a transition portion joining the flange portion to the reverse-buckling dome portion;
- wherein the dome portion defines an apex, and wherein the dome portion further defines an indentation at the apex;
- wherein the rupture disk includes a line of weakness configured to tear upon reversal of the dome portion;
- and
- wherein the line of weakness is a laser-ablated line of weakness imparted into the rupture disk at an angle other than normal to the disk surface.
A rupture disk, comprising:
- a flange portion;
- a reverse-buckling dome portion;
- and
- a transition portion joining the flange portion to the reverse-buckling dome portion;
- wherein the dome portion defines at least one laser-ablated line of weakness imparted into the dome portion at two or more oblique angles to the disk surface;
- and,
- wherein the at least one laser-ablated line of weakness is non-circular, eccentric to a diameter of the rupture disk, angular, or a combination of curved and angular.
