A flange 52 extends upwardly about a filling passage 50 and a flexible tubular valve member 54 having a bead 56 in tension about and in sealing engagement with the flange and extending through an inlet cavity 48 to an annular ring 58 presenting an upwardly facing conical seat 60 for sealing engagement with a poppet valve 62. A helical spring 64 is disposed about the tubular valve member 54 and engages the annular ring 58 to urge the annular ring 58 into engagement with the periphery 46 of the valve seat in the filling position. A mast 66 is connected to the poppet valve 62 and extends upwardly through the chamber 34 for moving the mast 66 vertically between the chamber 34 charging position, as shown in FIG. 4, and the container 11 filling position, as shown in FIG. 5.
