Claim:
A vacuum-operated trash receptacle comprising: a container having a tubular wall and an upper opening thereto through a rim of said wall; a rigid liner having a tubular wall, a top opening at a rim of said wall, and a closed bottom and disposed for placement in said container through the opening of the container so as to places the container and liner rims in sealing contact at upper portions thereof when the liner is inserted in the container; said liner adapted for receiving a trash bag through the opening of said liner; said liner dimensioned for insertion within said container with said liner opening in a fixed relation to said container opening and to thereby form an annular space between said liner wall and said container wall, the annular space terminating and sealed at the upper portions in contact; said liner wall having a plurality of apertures around and down its tubular wall from a location proximate said opening to a location proximate said closed bottom, said apertures communicating from the interior of said liner to said annular space when said liner is inserted into said container; an exhaust aperture through the container; and air blower means for withdrawing air from said annular space solely through the liner apertures through said container exhaust aperture wherein air pressure is reduced in said annular space and the trash bag is simultaneously held against and deployed progressively down said liner wall solely responsive to operation of said air withdrawing means whereby the deployment of said bag against said liner wall retains upper portions of said bag proximate said liner rim as said bag is deployed down said liner wall.
