Abstract
A pressure vessel including a lid with integral fixed lock tabs engageable with notches in the housing side wall to secure the lid to the housing. The housing includes a vent opening formed through the side wall. The lower edge of the lid is substantially bevelled and has a flattened portion to seal the vent when the lid is in its closed position. On opening of the lid, the seal between the vent and lid is broken before the fingers disengage the housing to vent residual pressure from within the housing.
