Abstract
A vented funnel for a closed head hazardous waste container. The container is of the type having side walls and opposed upper and lower end walls. The side walls and end walls of the container border and define a cavity which opens at an opening at the upper end wall. The funnel has a housing with a passage running through the housing. A lid is movably connected to the funnel housing through open and closed positions, in which the lid is configured to create a liquid and airtight seal within the funnel housing when in the closed position. One or more vent lines having openings at opposite ends thereof are disposed within the funnel housing passage. A drum coupling is then connected to the funnel housing and is connectable to the drum. The coupling has an interior surface bordering and defining a passage, wherein the coupling passage connects to the housing passage. One or more vent passages are disposed through the coupling, in which each such vent passage is connected at one end to a vent line, and open at an opposite end along an exterior surface of the coupling.
