Apparatus for preventing unintended or premature release of liquid in a beverage brewing device

摘要

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 (9), a closing member (12) and a recess (13). The apparatus is fabricated such that the pressure of the liquid being delivered to the brewing chamber displaces or depresses the closing member (12) sufficiently into the recess (13) to form a first fluid passage. The pressure of the fluid also creates a channel or cavity on a surface of the flexible member (9). The first fluid passage and the channel or cavity form a second fluid passages which provide fluid communication between the fluid inlet (5) and the brewing chamber. Preferably, the flexible member (9), closing member (12) and recess (13) is formed as an integral unit.
