Device for making coffee

Abstract

The present invention is directed to a portable device for making coffee. The portable device includes a vessel for holding a mixture of solid particles and liquid. The vessel has a bottom end and a side wall extending from the bottom end. The side wall terminates and defines a top opening for receiving the solid particles and liquid. The device includes a plunger assembly that has a filter unit and a rod extending from the unit. The filter unit has a hub for receiving the rod and a plurality of spokes extending substantially normal to the rod and radially from the hub to a peripheral base member. A filter extends between the hub and the peripheral base member. The peripheral base member has a plurality of fingers extending from the perimeter of the peripheral base member. The fingers each have a first phalange and a second phalange. The first phalange extends upwardly and outwardly from the peripheral base member and joins the second phalange at an angular intersection. The second phalange extends from the angular intersection upwardly and inwardly. The angular intersection sufficiently contacts the side wall of the vessel to form intimate contact between the vessel and filter unit.
