Device to assist extraction of beverage material in cartridges

A device for assisting extraction of a material contained in a cartridge for preparation of a beverage consisting of a wall, a flange connected to an upper portion of the wall, a rim, a plurality of fins, an area of fin convergence and a finger wherein:

• the wall forms a hollowed enclosure and has an interior wall surface which defines a frustoconically-shaped cavity having an opening surrounded by the flange for containing a cartridge containing a material to be extracted for preparation of a beverage;
• the flange intersects and extends laterally from the wall about and away from the opening;
• the rim intersects and extends laterally from the interior wall surface to form a peripheral rim base surface for supporting a cartridge contained by the interior wall surface;
• the fins are integral with the rim and extend from the rim laterally, with respect to the interior wall surface, and have edges facing the cavity which extend from the rim base surface and converge and connect at the area of fin convergence so that the area of fin convergence is centrally disposed with respect to the interior wall surface and rim and displaced at a distance away from a plane defined by the intersection of the interior wall surface and rim base surface;
• and
• the finger extends from the area of fin convergence towards the plane to a finger surface located below the plane and being displaced a distance away from a portion of the fin edges adjacent the area of fin convergence.
