An infusion beverage brewing system includes a container (21) and an infuser (30). The infuser (30) is positioned in a liquid (84), such as hot water, and has an infusing chamber (40) for containing infusible materials, such as tea leaves (85). A plunger (60) includes a piston (61) with a peripheral seal (83) and flap valves (72). After a brewing time has elapsed, an individual pushes on an operator (62) to move the piston (61) past a perforated wall portion (44) of the infusing chamber (40). When the piston (61) reaches a solid wall portion (43) at the bottom of the infusing chamber (40), the flap valves (72) open to allow liquid (84) to escape. However, small apertures aligned with the flap valves prevent the passage of the infusible material. Consequently the infusible material is isolated from the liquid (84) when the piston (61) reaches the solid bottom wall portion (43) of the infusing chamber (40). |
