WIPO Patent Application WO1999049122
Kind Code:
A9
Abstract:
A wash tank (10) adapted for use with a carbon dioxide cleaning medium has a body member (20) having a front opening (22) formed therein, the body member having side walls (23) and a back wall (24) opposite the front opening. The side walls terminate in a front body member edge portion (25) that defines the front opening. A substantially cylindrical basket (30) is disposed within the body member for rotation about a generally horizontal axis. The basket side wall terminates in a front basket edge portion defining the basket front opening. The said basket edge portion (32) is spaced forward from the body member edge portion (25) when the basket is positioned in the body member, serving to prevent loose garments or materials placed within the basket from becoming caught in the seal and interfering with seal integrity. A drive mechanism (50) is included to rotate the basket about the axis. A door (21) is hingeably (26) connected to the body member, with the door having a front wall and side walls, and with the side walls terminating in an inner edge portion (29) configured to abut said body member edge portion. The door inner edge portion (29) and the body member edge portion (25) comprise a seal for sealing the door and body member to form an enclosed pressure vessel. A plug (65) is connected to the door, the plug having a surface portion configured to abut the basket front opening when the door is closed. Methods and systems employing the tank are also disclosed.
