Abstract
Abstract A brewer assembly which is particularly useful for preparing small quantities of coffee or the like in a microwave oven, comprised of a cup for accepting the charge of ground coffee and water, and a lid in the configuration of an inverted basket with a plurality of screen-covered openings for filtering the brewed beverage as it is poured from the cup. A stem-shaped tube extends above the top surface of the lid forming a lid handle whose interior provides a channel for venting the steam generated during the heating process. The tube extends below the top surface of the lid to prevent the discharge of the unfiltered brewing mixture through the vent opening when the device is tipped for discharging the finished beverage.
