ABSTRACT:
A spigot for a beverage container includes a body having a passage with first and second ends formed therethrough. An annular shoulder extends into the passage proximate the first end thereof and an annular valve seat is formed proximate the second end. An elastomeric plunger positioned in the passage includes a button with a sealing flange seated against the annular shoulder and a valve head biased against the valve seat. The body further includes a plurality of fins extending radially into the passage, each fin has a first end adjacent the annular shoulder such that the first ends contact the sealing flange as the button is depressed. The fins act to inhibit the sealing flange from coming unseated from the shoulder.
