A conic funnel integrally connected to a supporting planar platform in combination with an essentially flat disposable filter that is transformed into a three-dimensional conic configuration disposed to be inserted into the conic funnel. The apex of the conic funnel is truncated and projected through a first circular orifice at the approximate center of the supporting planar platform such that an effluent is focused into a receiving vessel upon which the supporting planar platform is placed. A second orifice vents air displaced by the effluent. A tab-like member and/or handle are used to hold or hang the apparatus. The apparatus has special applications for brewing beverages such as coffee by using nonproprietary nonpreformed low-cost generic circular paper filters such as those used in consumer coffeemakers as well as eliminating auxiliary laboratory equipment needed to vertically hold Buchner type funnels.

I claim: 1. A conic funnel rigidly and fixedly integrally connected to a supporting planar platform in combination with a disposable filter means adapted to be reconfigured to a conic shape comprising:a conic funnel having an internal surface, external surface, upper rim, and truncated apex having a circular cross-section,a supporting planar platform having an upper surface and under surface perpendicularly oriented to the vertical axis of said conic funnel and a first circular orifice at the approximate center of said supporting planar platform at which orifice said truncated apex of said conic funnel is rigidly and fixedly integrally joined to said supporting planar platform and downwardly projected therethrough a sufficient distance below said under surface of said supporting planar platform to act as a means to prevent said supporting planar platform from slipping from the surface of a receiving vessel adapted to receive an effluent focused through said truncated apex of said conic funnel into the receiving vessel, said planar platform being adapted to a size to be supported by a supporting surface of a receiving vessel upon which said supporting planar platform has been placed and at which juncture between said first orifice in said supporting platform and external surface of said conic funnel additional extrusions of material have been placed to further support and stabilize said conic funnel to said supporting planar platform and a second circular orifice located at approximately one half the distance between the center of said first circular orifice and the downward projection of said rim of the said conic funnel disposed to vent the air displaced by an effluent delivered into a receiving vessel, andan essentially flat disposable filter means of such a size adapted to be formed by origami-like foldings into a conic configuration to conform, to said internal surface of said conic funnel and when opened to entirely cover said internal surface of said conic funnel and to be projected downwardly through said truncated apex of said conic funnel a suitable distance therebelow to focus an effluent into a receiving vessel and to be protected against rupture by said projecting truncated apex of said conic funnel.
