Vacuum container inside closure means for the access door

Abstract

A vacuum container compromising a vacuum producing means to create a vacuum within said container, a conduit to vacuum solids or liquids into the vacuum container, an access door and a means to close and/or open the access door from within the vacuum container. The door closure/opening means having door attachment means so as to equalize sealing pressures throughout the door sealing means. The door closure/opening means may be powered by a means disposed within the vacuum container or located external to the vacuum container. A means external to the vacuum container may be used to activate the internal door closure/opening means. Should the internal door closure means fail to open the door, an external fastener or access means may be used to override or remove the internal closure means.

What is claimed  
     
         1 . A vacuum container having an access door and having a means to close the door from within the vacuum container.  
     
     
         2 . The vacuum container as described in a  claim 1  wherein said vacuum container comprises one or more doors.  
     
     
         3 . The vacuum container as described in  claim 1  wherein said vacuum container comprises one or more door closure means disposed within the vacuum container.  
     
     
         4 . The vacuum container as described in  claim 1  wherein said vacuum container comprises one or more means to pull the debris door closed from within the vacuum container and utilizes door attachment means so as to seal the door closed.  
     
     
         5 . The vacuum container as described in  claim 1  wherein said door closure means utilizes a power source external to the vacuum container.  
     
     
         6 . The vacuum container as described in  claim 1  wherein said door closure means utilizes a fastener means external to the vacuum container.  
     
     
         7 . The vacuum container as described in  claim 1  wherein said door closure means also secures the door sealed closed until it is desired to open the door.  
     
     
         8 . The vacuum container as described in  claim 1  wherein said door closure means also has means to open said door.  
     
     
         9 . The vacuum container as described in  claim 1  wherein said door closure means and door opening means are powered.  
     
     
         10 . The vacuum container as described in  claim 1  wherein said door closure means or door opening means are manual.  
     
     
         11 . The vacuum container as described in  claim 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , or  10  wherein said door closure means is a linear actuator, a hydraulic cylinder, an air cylinder, a lever, a winch, a solenoid, a spring, or a gas spring.
