1. A pouch handling apparatus for separating a flexible pouch from a chain of flexible pouches, and filling the flexible pouch, the apparatus comprising: a presentation means for presenting at least one chain of flexible pouches into a feeder mechanism through which said chain of pouches passes, said flexible pouches being interlinked via their spouts, the feeder mechanism including a ratchet arm movable in a first direction wherein the ratchet arm will pivot away from the pouches passing by the chain of interlinked pouches without engaging them, and movable in a second opposite direction in which the ratchet arm engages with the chain of interlinked pouches and moves them into the feeder mechanism,a means operable to engage with a spout of an end pouch of said interlinked chain, and to convey said end pouch from the feeder mechanism towards a filling position,a means to pull, via the interlinked spouts, a remainder of the pouches towards the feeder mechanism;a means of separating a flexible pouch from an end of the chain of interlinked pouches;a means of filling a flexible pouch via the spout thereof in the filling position;a means of closing the spout; anda means of releasing the pouch from the pouch handling apparatus. 2. The pouch handling apparatus according to claim 1, wherein the means operable to engage with the spout comprises the feeder mechanism. 3. A pouch handling apparatus according to claim 1, wherein the pouch is filled at the filling position prior to being detached from the chain. 4. A pouch handling apparatus according to claim 1, wherein the pouch is detached from the chain prior to being filled at the filling position. 5. A pouch handling apparatus according to claim 4, wherein said means operable to engage with the spout and said means of separating a flexible pouch from the end of the chain comprises one and the same means. 6. A pouch handling mechanism according to claim 5, wherein said one and the same means comprises a linearly movable selector means arranged for movement substantially perpendicular to the direction of movement of the chain of interlinked pouches and wherein the perpendicular movement of the selector means detaches the selected pouch from the chain. 7. A pouch handling mechanism according to claim 5, wherein the means comprises a ridge, for location in a groove of the spout, and a pin, extendable through a cavity in the spout. 8. A pouch handling apparatus according to claim 1, wherein the spouts of the chain of pouches are provided with caps to maintain them internally clean, and the apparatus further comprises a means for removing the cap prior to filling. 9. A pouch handling apparatus according to claim 8, wherein the cap is removed at the filling position. 10. A pouch handling apparatus according to claim 8, wherein the cap is removed at a cap removal point remote from the filling position. 11. A pouch handling apparatus according to claim 8, wherein the means of closing the spout comprises the step of replacing the cap after the pouch has been filled. 12. A pouch handling apparatus according to claim 1, wherein the ratchet arm is arranged for linear movement. 13. A pouch handling apparatus according to claim 1, wherein the ratchet aim is arranged for rotary movement. 14. A pouch handling apparatus according to claim 1, further comprising a sprung retainer arm in a fixed position whereby when the pouches are moved into the feeder mechanism the retainer arm pivots to allow the chain of spouts to pass and whereby movement of the pouches in the opposite direction is prevented by engagement of the retainer arm with the chain of spouts. 15. A pouch handling mechanism according to claim 1, comprising: a plurality of presentation means, each presentation means having an associated feeder mechanism; means of filling a flexible pouch; means of closing the spout; means of separating a flexible pouch from the end of the chain of interlinked pouches; and a means of releasing the pouch from the pouch handling apparatus. 16. A pouch handling mechanism according to claim 1, further comprising a combined capping and filling mechanism for removing a cap from a pouch, filling the pouch with liquid and re-attaching a cap to the pouch to close the spout, said mechanism being movable in a horizontal and a vertical direction to present either a capper or a filling nozzle to the spout of a flexible pouch. 17. A pouch handling mechanism according to claim 16, wherein the combined capping and filling mechanism further comprises a filling head arranged to receive and retain an array of nozzles from a plurality of liquid supplies and the filling head is indexable to present a selected one of said nozzles to the spout to fill the pouch therethrough. 18. A pouch handling mechanism according to claim 17, further comprising a refrigeration cowling surrounding the filling head to enable refrigerated air to circulate around said filling head to maintain it in a refrigerated condition.
