Abstract: A cooler (100) for supplying cooled drinking water, particularly at remote outdoor locations, includes a reservoir (101) that supplies water to a conduit (119) for indirect cooling by a cooling medium, for example ice, contained in a container (105). A water bottle (103) is installed in the cooler (100) such that a feed tube (111) of the reservoir (101) penetrates and engages the hygienic seal (201) of the water bottle (103). The conduit (119) is connected to a discharge (113) on the reservoir (101) and a spigot (125). When the spigot (125) is opened, water passes through the conduit (119) and is indirectly cooled. As water is withdrawn from the cooler (100) at the spigot (125), air that replaces the withdrawn water enters the reservoir (101) through an air intake (115). The cooler (100) can have a filter (211) at the air intake (115) to prevent contamination by ambient air.
