An apparatus for use with a coffee maker holds the grounds in a cylindrical configuration in the hot water stream for more uniform and efficient extraction. A thin-wall, right cylinder has a slotted lower edge. A thin-wall frustum of a cone also has a smaller diameter, slotted lower edge. Both lower edges are resilient and cooperate with one another to hold the central portion of a filter elastically therebetween. The peripheral portion of the filter is held securely in the annular space between cylinder and frustum. The slots in the cylinder also provide for lateral liquid flow through the grounds as the volume of liquid in the cylinder increases. The frustum may be configured to facilitate use of a flat filter.

Apparatus for use with a coffee maker and a filter for containing coffee grounds from which flavoring components are separated by a vertical hot liquid stream, and permitting the discharge of liquid with extracted components therefrom while blocking the passage of ground coffee along with the extracted components, the apparatus comprising: A) a right cylinder having an upper edge and a lower edge and a thin wall, said lower edge being castellated with a plurality of slots extending upward from said lower edge to provide a resilient edge whose diameter may be elastically reduced by inward pressure thereon, said slots further providing for passage of liquid therethrough; B) a frustum of a cone having an upper margin and a lower margin and a thin wall, said lower margin having a lesser diameter than said upper margin and being castellated with a plurality of slot means extending upward therefrom to provide a resilient edge whose diameter may be elastically altered by pressure thereon; C) said castellated cylinder arranged within said castellated frustum to elastically retain a filter therebetween, said castellated edge elastically engaging an inner surface of a central portion of a filter and said castellated margin elastically engaging an outer surface of said central portion of said filter, whereby a space is provided between said cylinder and said frustum to securely retain a peripheral portion of said filter; and D) said cylinder holding said coffee grounds in a cylindrical configuration for more uniform and efficient extraction thereof.
