ABSTRACT:
Bottled water or other liquid is supplied via a bottle connector5for releasable sealing engagement with a neck formed on the bottle, and a transfer tube6to a reservoir7wherein the water may be cooled. The bottle connector5, the transfer tube6and the reservoir7are 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 tube21or a dip tube which also releases silver ions. Furthermore, the transfer tube6may be connected to the reservoir7via a reservoir connector29which may incorporate a draw tube31and one or more outlet tubes14, 36, e.g. leading to a discharge outlet, all of which release silver ions.
