Abstract
A pressure relief cap includes a body engageable with a container and rotatable about an axis to couple or decouple the body from the container, a handle is coupled to the body and rotatable about the axis in a loosening direction and an opposite, tightening direction and, a ring member coupled for co-rotation with the handle in the loosening direction. The cap includes relief valve assembly coupled to the body. The ring member and the body include a lost motion region in which the ring member is rotatable relative to the body in the loosening direction. Rotation of the ring member relative to the body in the loosening direction in the lost motion region opens the relief valve assembly. Rotation of the ring member in the loosening direction beyond the lost motion region causes the body to co-rotate with the ring member in the loosening direction.
