Adjustable tamper coffee apparatus, brewing machine utilizing such apparatus, and methods for making coffee

摘要

A coffee brewer that includes a brewing chamber, and a brewing cup filled with coffee that is removably received in the brewing chamber. The cup includes a bottom that acts as a tamping member, and this bottom is movable to vary the size of the cup reservoir. Once the cup is positioned in the brewer, the closing of the cup forces engagement of the tamping member and an engagement member positioner in the brewing chamber, resulting in the tamping member being moved to compress the coffee.

主权项

1. A beverage brewing apparatus comprising:
a brewer housing having a first component defining a brewing chamber with a bottom and with an access opening, a second component which may be opened to afford access to said brewing chamber via said access opening and which may be closed to coact in sealing engagement with said first component to close said access opening, and having an engagement portion; and, an impermeable brewing cup removably received in said brewing chamber, the brewing cup comprising a liquid impermeable cup housing defining a reservoir with a brewing material positioned therein, the cup housing comprising a tamping member wherein the tamping member is movable into and out of the reservoir to vary the size of the reservoir; wherein the engagement portion is within the brewing chamber and in contact with the tamping member, and when the second component is opened, holds the tamping member a set off distance from the bottom of the brewing chamber; wherein, once the second component is closed, the second component forces the housing portion to move toward the bottom of the brewing chamber while the engagement portion remains in contact with the tamping member and maintains the tamping member at the set off distance from the bottom of the brewing chamber, resulting in relative movement between the housing portion and the tamping member, and resulting in the tamping member being positioned a compression distance into the reservoir to compress the brewing material.
