Abstract

An apparatus useful for preventing the release of residual liquid in a beverage brewing device prior to and after the brewing process, and for preventing the premature release of liquid during the heating process is disclosed. The apparatus includes a flexible member, a closing member and a recess. The apparatus is fabricated such that the pressure of the liquid being delivered to the brewing chamber displaces or depresses the closing member sufficiently into the recess to form a first fluid passage. The pressure of the fluid also creates a channel or cavity on a surface of the flexible member. The first fluid passage and the channel or cavity form a second fluid passages which provide fluid communication between the fluid inlet and the brewing chamber. Preferably, the flexible member, closing member and recess is formed as an integral unit.
