An improved device for the preparation of individual coffee or tea beverages. A cylindrical, parallel walled container acts as both a brewing container and a drinking container. A plunger assembly is pushed down through the top of the container and effectively separates coffee grounds or the like from the brewed drink. A finely perforated disk having an upwardly oriented flange, is attached to the underside of a rigid perforated disk of the plunger assembly by means of a ribbed tab located at the center of the rigid perforated disk. Frictional attachment is made by inserting the ribbed tab of the rigid, perforated disk into the slot of the finely perforated disk. When removing the plunger assembly, the finely perforated disk detaches from the plunger assembly and remains in the bottom portion of the container thereby trapping the coffee grounds or the like between the finely perforated disk and the bottom of the container. The remaining brewed beverage can be drunk by a person in a similar way to a normal coffee mug. Upon completion of the beverage, the finely perforated disk can be removed and reattached to the plunger assembly for reuse.

A system for producing coffee or tea directly in a drinking vessel, comprising: a drinking vessel having interior side walls and a bottom, a substantially rigid disc with an outer edge having means for fitting closely against the interior side walls of the vessel while permitting up and down sliding movement along the side walls, said disc having perforations, a push rod secured to the substantially rigid disc and extending upwardly sufficiently to extend out of the top of the vessel, with gripping means at the top of the push rod for gripping by a hand of a user, cover means for the drinking vessel, for generally containing liquid from splashing out of the vessel, a second disc sized to fit closely within the interior side walls of the drinking vessel, the second disc being finely perforated such as to pass liquid but substantially to block passage of coffee grounds or tea leaves, and means for temporarily and releasably retaining the second disc immediately below and against the bottom of said substantially rigid disc, said means for retaining being such that the second disc is easily released from the substantially rigid disc upon upward movement of the push rod and substantially rigid disc when immersed in liquid, whereby coffee, tea or other beverages can be brewed directly in the drinking vessel by first placing coffee grounds or tea leaves or other infusible particulate flavoring material in hot water in the vessel to brew the beverage, then placing the substantially rigid disc and push rod down into the vessel with the second disc below, then pressing the push rod down to separate the coffee grounds or tea leaves out of the liquid and to press them firmly down against the bottom of the drinking vessel, and finally by removing the push rod and rigid disc from the vessel, leaving the second disc against the pressed coffee grounds or tea leaves at the bottom of the vessel.
