Abstract
Abstract A device for brewing a beverage into container, such as a cup, which includes an enclosure adapted to fit over the rim of a receiver such as a cup with a space between the bottom of the device and the receiver and where a reservoir is provided to receive granular or particulate material to be used in the brewing process. A removeable water apertured distributor plate is provided to be located above the reservoir with foot members provided to generally center the apertured plate and to provide an annular space around a part of the plate between the edge of the plate and the chamber defined by the enclosure. A filter is provided in the bottom of the reservoir to prevent loss of the particulate material which is being extracted into the receptical.

A device for brewing a beverage into receiver means having a bottom with upwardly extending wall means terminating at a rim defining a receiver opening to said receiver means; brewing shell means having a frusto conical mid section a longitudinal axis and having a base with a mean diameter greater than the diameter of said receiver opening, and outlet with mean diameter smaller than said receiver opening to be received within said receiver means and where the outer surface of said frusto conical mid section includes outwardly extending spacer means along a portion of the length thereof where said spacer means are received on said rim of said receiver means to define annular space between the frusto conical mid section and the receiver, means first wall means extending generally downwardly from the outlet of said frusto conical mid section defining a second opening; first perforated plate means extending across said second opening to define an extractant reservoir to receive particulate material to be used in a brewing process; second wall means extending upwardly from said base of said frusto conical mid section to define a water receptical to receive water, groove means extending around at least a portion of a defined joint between the base of the frusto conical mid section and said second wall means, and second perforated plate means having foot members which extend outwardly from the second perforated plate means with outwardly extending detents to be received in said groove means to hold said second perforated plate means in generally transverse relation to the longitudinal axis of said frusto conical mid section where the diameter of the second perforated plate means is lss than the inner mean diameter of said second wall means so an annular space is defined between said second wall means and the outer diameter of the second perforated plate means.
