A system for supplying liquid in large bottles from a point where they are filled to a dispenser having a reservoir for receiving the liquid. The bottles each have a neck which carries a cap unit for closing the spout thereof. Each cap unit has an outlet valve that is normally closed. The reservoir has means for supporting another normally closed inlet valve in a neck-receiving socket. When the neck is slipped into the socket the outlet valve of the cap unit is opened and substantially simultaneously the inlet valve for the reservoir is opened thus allowing flow of water from the bottle into the reservoir. When the bottle is removed from the reservoir as the cap unit is withdrawn from the neck-receiving socket, the outlet valve in the bottle neck cap unit is positively closed and the inlet valve of the reservoir automatically closes.

In combination a container for liquid having a projecting neck through which the liquid contents is to be dispensed and a dispenser having a reservoir for receiving said liquid when the container is inverted thereon; a cap and outlet valve assembly in said neck, said assembly comprising a cap carrying a guide structure and an annular slider outlet valve, said slider valve being mounted for sliding movement along said guide structure between a normally-closed position and an opened position; said guide structure having a length, being mounted on said cap and extending into the neck, means forming elongated outlet passages along said length, said guide structure comprising at least two arcuate surfaces engaging said slider outlet valve, said slider outlet valve having a length of substantially lesser extent than said passages to permit flow through said passages as the valve moves toward said opened position, a socket and inlet valve assembly mounted in cooperation with said reservoir, said socket and inlet valve assembly comprising an upwardly-opening neck-receiving socket having an axis which receives the neck of said container when inverted, said inlet valve including a valve stem carrying a valve body which is normally biased to closed position, a reservoir inlet leading from the said upwardly-opening socket into said reservoir and closed by said valve body when in closed position, a tubular probe coaxially mounted with an extending upwardly in said upwardly-opening socket, said valve stem being axially slidably mounted in said probe, said valve stem projecting upwardly from the probe so as to engage said slider outlet valve in the container neck when the neck is inverted in the upwardly-opening socket to move said slider outlet valve into said opened position, engagement of the stem with said slider outlet valve also moving the stem downwardly in said probe to move said valve body carried thereby into said opened position form said normally-biased closed position, resilient gripping fingers on said slider outlet valve for engaging the guide structure to normally hold the outlet valve in said normally-closed position, said fingers being arranged in groups annularly spaced to align with said guide structure, said slider outlet valve having guide structure engaging means projecting into each of said passages for engaging the guide structure to prevent rotation of said outlet valve to keep the groups of fingers in alignment with said guide structure.
