Abstract
Device and method for making beverage from flavor-containing materials comprises a body connected to a container for allowing the formation of a dispersion of flavor-containing materials in liquid and the extraction of the flavor-containing materials to produce a beverage, a porous filter connected to the body and having a first surface for contacting the dispersion, filtration openings for allowing the beverage in the dispersion to pass through but blocking the flavor-containing materials and a second surface in communication with a beverage outlet from which the beverage may be poured or drunk, and a cling-on chamber on the body adapted to form a vacuum therein to suck to the interior surface of the container, thereby allowing the container to be tilted to generate a liquid head to drive the beverage out of the container through the filtration openings. The device may further include a blending/mixing mechanism to stir or break the flavor-containing materials and liquid for generating a visually appealing crema layer on the dispersion and/or facilitating the extraction of the flavor-containing materials by the liquid, and a flow facilitator having a selective opening for increasing the beverage flow through the filtration openings and preventing the flavor-containing materials in the dispersion from getting out of the container in the event that the dispersion covers the selective opening under a liquid head or force.
