## Abstract

An appliance comprising a unitary, atmospheric pressure, equilization chamber and drying chamber in the form of a sealed, flexible walled container with open cell elastomeric material providing communication between the interior of the chamber and the zone between facing surfaces of adjacent panes of glass.

## Claims

### Claim 1

A multiple-glazed window structure comprising:
at least two substantially parallel and spaced apart panes having an outer periphery defined by the outer marginal edges of said panes;
an impervious gasket means disposed between the facing surfaces of said panes, said impervious gasket means extending along only a portion of the outer periphery of said panes and having spaced apart end portions defining the remaining portion of the outer periphery;
a pervious gasket means disposed between the facing surfaces of said panes and extending between the ends of said impervious gasket means along the remaining portion of the outer periphery of said panes, said pervious gasket means and said impervious gasket means cooperating to define a chamber between said panes;
an impervious flexing container positioned along the outer periphery of said panes adjacent said pervious gasket means, said container having an interior in fluid communication with said chamber through said pervious gasket means;
a desiccant within the interior of said flexible container; and
frame members supporting said panes and compressing said impervious and said pervious gasket means between said panes; said impervious gasket means, said container, and said panes defining a closed zone generally impervious to the ambient atmosphere.

### Claim 2 (depends on 1)

The invention defined in claim 1 wherein said impervious gasket means comprises an elongate strip of closed cell elastomeric material, said pervious gasket means comprises a short strip of open cell elastomeric material and said flexible container is formed of impervious plastic sheet material.
