Latching Drum Lid With Integral Exhaust Hood

Abstract

An apparatus for attaching to an opening of a drum that includes a lid, a base for attaching to the opening of the drum, a circular inner wall formed on the base, a circular outer wall formed on the base and extending between the base and the lid, the circular outer wall being circumferentially spaced about the circular inner wall and defining an open space therebetween, and an exhaust opening formed on an outer surface of the circular outer wall.

1 . An apparatus for attaching to an opening of a drum, comprising:
 a lid;   a base for attaching to the opening of the drum;   a circular inner wall formed on the base;   a circular outer wall formed on the base and extending between the base and the lid, the circular outer wall being circumferentially spaced about the circular inner wall and defining an open space therebetween; and   an exhaust opening formed on an outer surface of the circular outer wall.   
     
     
         2 . The apparatus of  claim 1 , wherein the base attaches to a periphery of the opening of the drum. 
     
     
         3 . The apparatus of  claim 2 , wherein the base includes a circular ring defining a base opening, the base opening positionable adjacent the opening of the drum. 
     
     
         4 . The apparatus of  claim 1 , wherein the lid is hinged to the circular outer wall. 
     
     
         5 . The apparatus of  claim 1 , wherein the lid includes a latch assembly for securing the lid to the circular outer wall. 
     
     
         6 . The apparatus of  claim 1 , wherein the lid includes a gasket for engaging a top portion of the circular outer wall to create a seal therebetween. 
     
     
         7 . The apparatus of  claim 1 , wherein the base includes a gasket for engaging the opening of the drum to create a seal therebetween. 
     
     
         8 . The apparatus of  claim 1 , wherein the circular inner wall and the circular outer wall are structured and arranged to establish air flow from the opening of the drum to the exhaust opening. 
     
     
         9 . The apparatus of  claim 1 , further including means for latching the base to the opening of the drum. 
     
     
         10 . A latching drum lid with an integral exhaust, comprising:
 a lid;   a base opposing the lid;   a circular inner wall formed on the base;   a circular outer wall formed on the base and extending between the base and the lid, the circular outer wall being circumferentially spaced about the circular inner wall and defining an open space therebetween; and   an exhaust opening formed on an outer surface of the circular outer wall.   
     
     
         11 . The latching drum lid with an integral exhaust of  claim 10 , wherein the base attaches to a periphery of an opening of a drum. 
     
     
         12 . The latching drum lid with an integral exhaust of  claim 11 , wherein the base includes a circular ring defining a base opening, the base opening positionable adjacent the opening of the drum. 
     
     
         13 . The latching drum lid with an integral exhaust of  claim 10 , wherein the lid is hinged to the circular outer wall. 
     
     
         14 . The latching drum lid with an integral exhaust of  claim 10 , wherein the lid includes a latch assembly for securing the lid to the circular outer wall. 
     
     
         15 . The latching drum lid with an integral exhaust of  claim 10  wherein the lid includes a gasket for engaging a top portion of the circular outer wall to create a seal therebetween. 
     
     
         16 . The latching drum lid with an integral exhaust of  claim 11 , wherein the base includes a gasket for engaging the opening of the drum to create a seal therebetween. 
     
     
         17 . The latching drum lid with an integral exhaust of  claim 11 , wherein the circular inner wall and the circular outer wall are structured and arranged to establish air flow from the opening of the drum to the exhaust opening. 
     
     
         18 . The latching drum lid with an integral exhaust of  claim 11 , further including means for latching the base to the opening of the drum. 
     
     
         19 . A latching drum lid with an integral exhaust, comprising:
 a lid;   a base opposing the lid;   a circular inner wall formed on the base;   a circular outer wall formed on the base and extending between the base and the lid, the circular outer wall being circumferentially spaced about the circular inner wall and defining an open space therebetween; and   exhaust means for establishing an airflow from the inside of the latching drum lid to the outside of the latching drum lid.   
     
     
         20 . The latching drum lid of  claim 19 , wherein the exhaust means includes an exhaust duct formed on an exterior surface of the latching drum lid.
