Abstract
A device for assisting extraction of a material contained in a cartridge for preparation of a beverage has a wall which forms a hollowed enclosure which has an interior surface which defines a frustoconically shaped cavity for containing the cartridge. A rim intersects and extends laterally from the interior surface of the wall to form a peripheral rim base surface which intersects the wall for supporting a cartridge contained by the interior wall surface. A plurality of fins integral with the rim extend from the rim laterally, with respect to the interior wall surface, to converge and connect at an area which 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 and rim base surfaces so that the area of convergence is displaced away from a cartridge contained and supported by the wall and rim base surfaces. A finger is disposed centrally in the area of convergence of the fine and extends towards the plane.
