发明名称 Infusion press lid assembly
摘要 An infusion press lid assembly is taught consisting of a lid body having a configuration capable of attaching to a straight walled beverage containing vessel. An actuator lever (44) pivotally engages a lid body (20) with a pouring valve (56) embraced by the actuator lever. A plunger rod (70) is disposed within the lid body and a plunger knob (76) is attached to the plunger rod for manually pushing the rod away from the lid body. A piston (82) is attached to the plunger rod, with the piston having bottom screen (84); a hub (86), an outer ring (88) and a number of reinforcing spokes (90). A seal retainer (92) is disposed within a groove (94) around the piston's periphery and a lip seal (96) is positioned within seal retainer. When an infusible media is placed within a beverage containing vessel and hot water is poured over the media and the lid body is attached, after steeping a brewed beverage is formed. The piston is depressed passing through the beverage which includes media residual debris that is captured by the screen under the piston, when completely depressed the pouring valve may be released allowing the purified beverage to be sipped or poured from the container.

主权项 1. An infusion press lid assembly which comprises; a lid body having a liquid pouring opening, a centered bore and a valve pivot opening, with the lid body further having a configuration capable of attaching onto and penetrating a straight walled beverage containing vessel, wherein said lid body further comprises a resilient double lip seal disposed within a groove in said lid body adjacent to a bottom portion, an actuator lever pivotally engaging a top portion of the lid body, with the actuator lever having a counterweight end and a lever operating end, a pouring valve having a pivot point member seated in the lid body having said body valve pivot opening to contain the pouring valve, the pouring valve defining a valve body with a top and a bottom, the bottom covering the liquid pouring opening and the top embraced by the actuator lever, a plunger rod having an upper end and a lower end slideably disposed within the centered bore of the lid body, a plunger knob attached to the upper end of the plunger rod for grasping and manually pushing the rod downwardly away from the lid body, and a piston attached to the lower end of the plunger rod, with the piston having a screen, a hub, an outer ring, a resilient seal retainer disposed within a groove in said piston periphery, wherein said screen is stainless steel and permanently disposed within said piston between said hub and said outer rim, when an infusible media is placed within the beverage containing vessel and hot water is poured over the media and the lid body is attached, after steeping a brewed beverage is formed, the piston is depressed passing through the beverage which includes media residual debris that is captured under the piston, when completely depressed the pouring valve may be released allowing the purified beverage to be sipped or poured from the container.
