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 form 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 When the bottle is removed from the reservoir as the cap unit is withdrawn from the neck-receiving socket, the outlet valve in the bottle neck cap unit is positively closed and the inlet valve of the reservoir automatically closes.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 is dispensed, a cap and valve assembly for said neck, said cap and valve assembly having an outwardly opening socket for receiving the neck and a valve guide, a slider valve slidably mounted within the valve guide and controlling flow of liquid from the neck, a dispenser having an upwardly-opening reservoir for receiving said liquid, said reservoir having an annular wall, a neck-receiving socket member having a depending annular skirt depending into said reservoir and spaced from said annular wall, said socket member having a socket for receiving said neck which has an outlet, a slidable valve for controlling said outlet, said slidable valve comprising an upstanding guide and a slidable valve stem therein projecting upwardly above the guide, said stem having a valve head thereon, said upstanding guide having a seat, and a spring on said guide which normally biases the head onto said seat, and sealing means between the annular skirt on the socket member and the annular reservoir wall for providing an hermetic seal therebetween, said sealing means being in the form of a flexible gasket of C-cross-section, and means for expanding the gasket, said expanding means comprising means for producing relative axial movement between the annular skirt on the socket member and the annular wall of the reservoir.
