Abstract
A beverage-brewing apparatus is provided which includes an outer cup member and an inner cup member. The outer cup member includes an open top, a sidewall and a bottom. The inner cup member has a sidewall, a first seal and a basket portion, with the sidewall of the inner cup member dimensioned to fit within the sidewall of the outer cup member. The first seal is disposed along an outer surface of the inner cup member for engaging the inner sidewall of the outer cup member to form a seal while still permitting the inner cup member to move within the outer cup member. The basket portion of the inner cup member is disposed at the bottom of the inner cup member. The basket portion includes a base with at least one aperture and a first filter medium, a sidewall, and a cap member having at least one aperture and a second filter medium. The cap member is releasably connected to the sidewall of the basket portion so that brewing material can be securely retained within the basket portion between the filter medium. The inner cup member is slidable between a first upper position where the basket portion of the inner cup member is disposed above the base of the outer cup member and a second lower position where the basket portion of the inner cup member is disposed against the base of the outer cup member such that liquid is forced through the basket portion when the inner cup member moves between the first and second positions with the first seal engaging the sidewall of the outer cup member. The apparatus preferably includes a lid having an aperture which is secured to the apparatus to close the apparatus.
