A beverage container is filled and sealed by: a) dispensing a predetermined amount of beverage, preferably wine, into an open-topped container having a circular rim, preferably a plastics wine glass, to leave a headspace above the beverage in the container; b) temporarily tacking a generally flat flexible film lid sized to fit over the open top to the rim of the container at at least one position around the rim while leaving the remainder of the rim free; c) engaging the tacked lid to cause flexure thereof to create a gap between the lid and the rim on one side; d) dispensing an inert gas, preferably nitrogen, through the gap so created and into the headspace to displace air therefrom; and e) bringing a heat sealer into engagement with the lid to heat seal the lid to the rim about its entire circumference, thereby trapping the inert gas within the headspace.

1. A method of filling and sealing a beverage container of the kind from which a user may drink, the method comprising the following steps in order: a) dispensing a predetermined amount of beverage into an open-topped container having a rim to leave a headspace above the beverage in the container;b) placing a flexible film lid flat on top of the container touching the entire rim of the container, the film lid having a tab extending beyond the rim of the container;c) temporarily tacking the film lid to the rim of the container at at least one position around the rim while leaving the remainder of the rim free;d) engaging the tab of the tacked lid by relative vertical movement between the container and a ring an inner boundary of which defines an area slightly larger than an area defined by an external boundary of the container at its rim to cause flexure of the lid from its flat state to create a gap between the lid and the rim;e) dispensing an inert gas or substantially oxygen free gas or gases through the gap so created and into the headspace to displace air therefrom; andf) bringing a heat sealer into engagement with the lid to heat seal the lid to the rim about its entire circumference, thereby trapping the inert gas or substantially oxygen free gas or gases within the headspace;wherein the sealed lid is adapted for subsequent manual removal using the tab to open the sealed container to allow a user to drink from the container. 2. The method of claim 1, wherein the ring takes the form of a skirt and the inert gas is supplied via the skirt, which serves to partially contain the inert gas or substantially oxygen free gas or gases. 3. The method of claim 2, wherein a flush of inert gas or substantially oxygen free gas or gases is timed to coincide with the skirt engaging the tab. 4. The method of claim 2, wherein the heat sealer is generally annular and mounted coaxially with the skirt for relative movement between the heat sealer and container to bring the heat sealer into engagement with the lid while the container is within the ring. 5. The method of claim 1, wherein the container comprises a goblet formed of polyethylene terephthalate. 6. The method of claim 1, wherein the lid is dispensed from a stack of lids in a hopper or cassette by a suction arm. 7. The method of claim 6, wherein the lid dispensing suction arm swivels from a position in which the arm engages a lowermost lid of the stack to a position in which the arm places the lid atop the rim of the container. 8. The method of claim 6, wherein the suction arm includes a spot heat sealer, and the spot heat sealer provides the temporary tacking. 9. The method of claim 1, wherein the method is performed on an indexed turntable, with successive index positions for (i) filling, (ii) initial application of a lid, (iii) flexure and inert gas flush and final seal and (iv) presenting the filled and sealed container to a packaging conveyor. 10. A system for filling and sealing a beverage container of the kind from which a user may drink, the system comprising: a) a dispenser adapted to dispense a predetermined amount of beverage from a supply thereof into an open-topped container having a rim to leave a headspace above the beverage in the container;b) a device arranged to place a flexible film lid flat on top of the container touching the entire rim of the container, the film lid having a tab extending beyond the rim of the container;c) a tacking device adapted to tack the film lid to the rim of the container at at least one position around the rim while leaving the remainder of the rim free;d) a ring an inner boundary of which defines an area slightly larger than an area defined by an external boundary of the container at its rim, and means for causing vertical movement of the ring relative to the container to cause engagement of the ring with the tab of the tacked lid to cause flexure of the lid from its flat state to create a gap between the lid and the rim;e) a dispenser adapted to dispense an inert gas or substantially oxygen free gas or gases from a supply thereof through the gap so created and into the headspace to displace air therefrom; andf) a heat sealer configured to be brought into engagement with the lid to heat seal the lid to the rim about its entire circumference, thereby trapping the inert gas or substantially oxygen free gas or gases within the headspace. 11. The system of claim 10, wherein the ring takes the form of a skirt coupled to supply the inert gas via the skirt, which serves in use to partially contain the inert gas or substantially oxygen free gas or gases. 12. The system of claim 11, wherein the heat sealer is generally annular and mounted coaxially with the skirt for relative movement between the heat sealer and container to bring the heat sealer into engagement with the lid while the container is within the ring. 13. The system of claim 10, wherein the device arranged to place a flexible film lid flat on top of the container touching the entire rim of the container is adapted to dispense the lid from a stack of lids in a hopper or cassette using a suction arm. 14. The system of claim 13, wherein said lid dispensing suction arm is adapted to swivel from a position in which the arm engages a lowermost lid of the stack to a position in which the arm may place the lid atop the rim of the container. 15. The system of claim 13, wherein the suction arm includes a spot heat sealer and the spot heat sealer provides said tacking device.
