Pressure relief assemblies and methods

A venting system, comprising:

• a container comprising a sidewall and defining a central longitudinal axis, and a line segment that is measured from the central longitudinal axis to an outermost surface of the container,
• a lid that is coupled with the container at an open end thereof;
• and
• a pressure relief feature that is disposed within a sidewall of the container,
• wherein the pressure relief feature includes a thinned region that defines a minimum thickness that is less than 40% of a maximum thickness of the sidewall of the container,
• wherein the pressure relief feature extends at least 180 degrees about the central longitudinal axis, and
• wherein the pressure relief feature is located at a radial distance from the central longitudinal axis of more than 95% of the line segment.

A venting system, comprising:

• a wall of a lid or a container, the lid or container defining a central longitudinal axis, and a line segment that is measured from the central longitudinal axis to an outermost surface of the lid or container;
• and
• a pressure relief feature that is disposed along the lid or container,
• wherein the pressure relief feature includes a thinned region of the lid or container that defines a minimum thickness that is less than 40% of a maximum thickness of the wall of the respective lid or container, and
• wherein the thinned region is defined by a curved surface and at least one flat surface on opposing sides thereof.
