Abstract
A rectangular rupture disk comprising sheet metal includes an edge region with which the rupture disk is fastenable to an opening of a container or of a conduit. In the edge region, the rupture disk has a fold-over including a first folded over part of the sheet metal and a second part of the sheet metal to which the first folded over part is parallel or predominantly parallel. The rupture disk further includes a central region with which the opening is sealable until the container or conduit reaches a bursting pressure, and predetermined breaking lines along which the rupture disk ruptures to at least partially open the central region in response to the container or conduit reaching the bursting pressure.

A rectangular rupture disk, comprising:
- a sheet metal comprising:
- an edge region with which the rupture disk is fastenable to an opening of a container or of a conduit, the rupture disk comprising in the edge region a fold-over including a first folded over part of the sheet metal and a second part of the sheet metal to which the first folded over part is parallel;
- a first shoulder area located in the second part of the sheet metal;
- a central region with which the opening is sealable until the container or conduit reaches a bursting pressure;
- and
- predetermined breaking lines along which the rupture disk ruptures to at least partially open the central region in response to the container or conduit reaching the bursting pressure, wherein:
- in a region between an outer edge of the rupture disk and the first shoulder area, either a space lies between the first folded over part and the second part, or the first folded over part and the second part lie against each other, and
- inboard of the first shoulder area, the first folded over part and the second part lie against each other.
A rectangular rupture disk, comprising:
- a sheet metal comprising:
- an edge region with which the rupture disk is fastenable to an opening of a container or of a conduit, the rupture disk comprising in the edge region a fold-over including a first folded over part of the sheet metal and a second part of the sheet metal to which the first folded over part is parallel, wherein the fold-over includes holes to receive screws to secure the rupture disk to an edge of the opening;
- a first shoulder area located in the second part of the sheet metal;
- a central region with which the opening is sealable until the container or conduit reaches a bursting pressure;
- and
- predetermined breaking lines along which the rupture disk ruptures to at least partially open the central region in response to the container or conduit reaching the bursting pressure,
- wherein a space lies between the first folded over part and the second part in a region between an outer edge of the rupture disk and the first shoulder area, and the first folded over part and the second part lie against each other inboard of the first shoulder area.
