Abstract
A closure 20 for a pressurized container having a plate with a top side 24 and a bottom side 28, a first notch 22 that extends about a first axis A1 along the top side, and a second notch 26 that extends about the first axis along the bottom side. The first and second notch form a membrane 62 that is capable of being ruptured when a maximum pressure causes the membrane to rupture.
Claims19
A closure for a pressurized container, comprising:
- a plate with a top side and a bottom side;
- a first notch that extends about a first axis along the top side;
- and
- a second notch that extends about the first axis along the bottom side,
- wherein the first and second notch form a membrane therebetween that is capable of being ruptured when a maximum pressure causes the membrane to rupture,
- wherein at a first location the first notch defines a first minimum width measured parallel to a second axis that extends perpendicular to the first axis and the second notch defines a second minimum width measured parallel to the second axis,
- wherein at a second location, disposed radially opposite the first location relative to the first axis, the first notch defines a third minimum width measured parallel to the second axis and the second notch defines a fourth minimum width measured parallel to the second axis,
- wherein the first minimum width is larger than the second minimum width, and the third minimum width is different than the fourth minimum width,
- wherein the first notch defines a first maximum depth measured parallel to the first axis and the second notch defines a second maximum depth measured parallel to the first axis, and
- wherein the first maximum depth is greater than the second maximum depth.

A closure for a pressurized container, comprising:
- a plate with a top side and a bottom side, the top side defining a first diameter;
- p1 a first notch that extends about a first axis along the top side, the first notch defining an inner surface, an outer surface, and a bottom surface disposed between the inner surface and the outer surface, the inner surface being closer to the first axis than the outer surface, the first notch further defining a second diameter;
- and
- a second notch that extends about the first axis along the bottom side,
- wherein the inner surface defines a first plane that is tangent to a first point along the inner surface and the outer surface defines a second plane that is tangent to a second point along the outer surface,
- wherein a line between the first point and the second point is orthogonal with respect to the first axis,
- wherein the first plane and the second plane intersect to define a first angle of between 65.000 degrees and 180.000 degrees,
- wherein a ratio of the second diameter to the first diameter is between about 0.700 and about 0.990,
- wherein a first maximum depth of the first notch is greater than a second maximum depth of the second notch, and
- wherein a first minimum width of the first notch is greater than a second minimum width of the second notch.

- a second notch that extends about the first axis along the bottom side,
- wherein a ratio of the second diameter to the first diameter is between 0.700 and about 0.990,
- wherein the first notch defines a first minimum width measured parallel to a second axis that extends perpendicular to the first axis and the second notch defines a second minimum width measured parallel to the second axis,
- wherein the first minimum width is larger than the second minimum width,
- wherein the first notch defines a first maximum depth measured parallel to the first axis and the second notch defines a second maximum depth measured parallel to the first axis, and
- wherein the first maximum depth is greater than the second maximum depth.
