<p>The electrical heater, water reservoir, syphon tube, jug and hotplate are similar to those used in previous coffee machines. The novel feature is that the ground coffee is contained in a disposable porous sachet, which is designed to allow max. surface area. The sachet (7), which is placed in a tray above the jug funnel, is sealed (8) at each end and has folds (9) along each side. As the water soaks into the ground coffee, the coffee expands, causing the sachet to swell and expose the folds along its edges. @(8pp Dwg.No.2/4)@.</p> |
