<p>Bottled water or other liquid is supplied via a bottle connector (5) for releasable sealing engagement with a neck formed on the bottle, and a transfer tube (6) to a reservoir (7) wherein the water may be cooled. The bottle connector (5), the transfer tube (6) and the reservoir (7) are all moulded of a plastics material containing silver bound in a ceramic ion exchange resin so that the silver ions (Ag+) are slowly released to prevent microbial growth on the surface of the components. The bottle connector may include a feed tube (21) or a dip tube which also releases silver ions. Furthermore, the transfer tube (6) may be connected to the reservoir (7) via a reservoir connector (29) which may incorporate a draw tube (31) and one or more outlet tubes (14, 36), e.g. leading to a discharge outlet, all of which release silver ions.</p> |
