摘要：
A safety pressure relief device comprises an annular flange portion (22), a concave/convex dome portion (24) and a transition portion (26) between the flange portion (22) and the dome portion (24), the transition portion (26) comprising a linear extent (28) extending from the annular flange portion (22) at a first acute angle (theta1) to the plane of the flange portion (22), a tangent to the dome portion (24) at its junction with the transition portion (26) making a second acute angle (theta2) with the plane of the flange portion (22) which is greater than said first angle (theta1), a line of weakness being formed in and around part at least of the linear extent (28) of the transition portion (26).
