Trash receptacle lid having a pumping apparatus

Abstract

An assembly having a trash receptacle with a lid. The receptacle includes a trash bag or liner attached thereto. The assembly includes a pumping device designed to expand the liner within the inner cavity of the receptacle by either pressuring the area within the liner or by evacuating the air trapped between the liner and the receptacle.

What is claimed is:  
     
         1 . A lid for use with a receptacle comprising: 
 a base, said base having a seal; and    a pumping apparatus for pressurizing the inner cavity of a receptacle.    
     
     
         2 . The lid as recited in  claim 1 , wherein said pumping apparatus is a bellows.  
     
     
         3 . The lid as recited in  claim 1 , wherein said pumping apparatus is an electronic pump.  
     
     
         4 . An assembly comprising: 
 a receptacle having a bottom wall and a side wall extending from said bottom wall defining an inner cavity and terminating at an upper edge;    a lid fitting about the upper edge of the receptacle;    a pumping apparatus for pressurizing the inner cavity of the receptacle.    
     
     
         5 . The assembly as recited in  claim 4 , wherein said pumping apparatus comprises: 
 a bellows; and    at least two valves oriented to pressurize the inner cavity.    
     
     
         6 . The assembly as recited in  claim 5 , wherein each of said valves comprises: 
 a first housing;    a second housing attached to the first housing defining an inner cavity;    a flapper valve located within the inner cavity to permit unidirectional airflow.    
     
     
         7 . The assembly as recited in  claim 5 , wherein at least one of said valves is a flapper valve.  
     
     
         8 . The assembly as recited in  claim 5 , wherein at least one of said valves is a duckbill valve.  
     
     
         9 . The assembly as recited in  claim 4 , wherein said lid further includes a seal.  
     
     
         10 . The assembly as recited in  claim 4 , wherein said receptacle further comprises: 
 a domed portion having at least one hole therethrough;    at least one channel in communication with said domed portion.    
     
     
         11 . The assembly as recited in  claim 4 , wherein said receptacle further comprises: 
 a handle having a scalloped portion terminating at a ledge.    
     
     
         12 . The assembly as recited in  claim 11 , wherein said handle further comprises a hole.  
     
     
         13 . An assembly comprising: 
 a receptacle having a bottom wall and a side wall extending from said bottom wall defining an inner cavity and terminating at an upper edge, said receptacle having an opening;    a lid fitting about the upper edge of the receptacle;    a pumping apparatus; and    a hose interconnecting the pumping apparatus to the opening in the receptacle for evacuating the inner cavity.    
     
     
         14 . The assembly as recited in  claim 13 , wherein said pumping apparatus comprises: 
 a bellows; and    at least two valves oriented to pressurize the inner cavity.    
     
     
         15 . The assembly as recited in  claim 14 , wherein each of said valves comprises: 
 a first housing;    a second housing attached to the first housing defining an inner cavity;    a flapper valve located within the inner cavity to permit unidirectional airflow.    
     
     
         16 . The assembly as recited in  claim 14 , wherein at least one of the valves is a flapper valve.  
     
     
         17 . The assembly as recited in  claim 14 , wherein at least one of the valves is a duckbill valve.  
     
     
         18 . The assembly as recited in  claim 13 , wherein said lid further includes a seal.  
     
     
         19 . The assembly as recited in  claim 13 , wherein said receptacle further comprises: 
 a domed portion having at least one hole therethrough;    at least one channel in communication with said domed portion.    
     
     
         20 . The assembly as recited in  claim 19 , wherein said assembly further includes a valve associated with said hole for permitting unidirectional airflow through said hole in the dome portion.  
     
     
         21 . An assembly comprising: 
 a receptacle having a bottom wall and a side wall extending from said bottom wall defining an inner cavity and terminating at an upper edge, said receptacle having an opening; and    a lid fitting about the upper edge of the receptacle; and    an electronic pumping apparatus for pressurizing the inner cavity.    
     
     
         22 . An assembly comprising: 
 a receptacle having a bottom wall and a side wall extending from said bottom wall defining an inner cavity and terminating at an upper edge, said receptacle having an opening;    a lid fitting about the upper edge of the receptacle;    an electronic pumping apparatus; and    a hose interconnecting the electronic pumping apparatus to the opening in the receptacle for evacuating the inner cavity.    
     
     
         23 . An assembly comprising: 
 a receptacle having a bottom wall and a side wall extending from said bottom wall defining an inner cavity and terminating at an upper edge;    a liner sealing attached to said receptacle and fitted within the inner cavity;    a lid fitting about the upper edge of the receptacle; and    a pumping apparatus in communication with the inner cavity of the receptacle and configured to expand the liner within the receptacle.
