    Abstract: FILM-WISE MANNER. VAPOR IS FORMED IN THE SPACES BETWEENTHE VERTICAL SURFACES AND IS REMOVED IN A DIRECTION SUBSTANTIALLY TRANSVERSE TO THE DOWNWARD FALLING FILM FLOW. THE VAPOR SO PRODUCED EXHIBITS A VERY LOW ENTRAINMENT LEVEL.

    A LIQUID SUCH AS WATER ENTERS A CHAMBER MAINTAINED AT A PRESSURE BELOW ITS SATURATION PRESSURE SO THAT A PORTION OF THE FEED LIQUID IS FLASH EVAPORATED AND A PORTION DISCHARGED AT A REDUCED TEMPERATURE. THE EVAPORTION IS EFFECTED BY DISTRIBUTING THE FEED LIQUID OVER A PLURALITY OF PARALLEL, CLOSELY SPACED AND SUBSTANTIALLY VERTICAL SURFACES UPON WHICH THE LIQUID FLOWS DOWNWARDLY IN FALLING

    Abstract: An outer closure member having a top panel and depending skirt portion. An inner closure member composed of a different material having an annular vertical wall disposed within the outer closure member and a radially outwardly directed flange integrally formed with the lower marginal edge of the annular vertical wall. An upstanding wall segment on the flange cooperating the flange and the annular vertical wall to define an upwardly open channel. The marginal end of the outer member skirt portion resiliently retained within the channel to prevent accidental relative separation of the outer and inner members but permitting intentional mechanical separation. The outer closure member may be a metal closure having an integral opening device and the inner closure member may be a molded resilient plastic material and adapted to serve both as a gasket and reclosure.
