Abstract
The combined relief valve and lid is for pre-mix beverage and syrup containers, having a tubular body enclosing a relief port in the lid. An annular valve seat surface about the relief port is raised higher than the lid surface and drain ports extend from the valve seat surface down to the lid surface to enhance drainage of the entire internal portion of the valve body. The relief port is closed by a spring biased poppet and has a biasing spring held in place in the top of the tubular body by a one-way detent and retainer clip which must be destroyed to remove it from the valve body to gain access to the relief valve poppet. The valve cannot be tampered with unless this retainer clip for the valve spring is destroyed.
