Abstract
A propane tank with a valve passage containing a valve has a protection cap with a projecting pin which extends into the passage adjacent the valve to provide a secondary seal. The projecting pin is defined by an annular sleeve surrounding a hollow interior extending up to the upper wall where the sleeve has an outside surface tapered from the upper wall to the remote end and an inside surface tapered from the remote end to the upper wall and the passage carries an O-ring seal arranged so that movement of the upper wall in a direction away from the passage caused by pressure release is insufficient to cause release of the secondary seal between the projecting pin member from the O-ring seal. The projecting element extends into the hollow interior to a position beyond the remote end of an actuating pin of the valve.
