  • Patent number: 8998036
    Abstract: A dispenser including a base unit with an actuation mechanism for dispensing liquid and a refill unit insertable into the base unit in an inverted configuration with its outlet lowermost for the supply of liquid to the base unit. The refill unit includes an annular wall projecting into the refill unit and defining an outlet from the refill unit, the annular wall being closable at its innermost end by a valve element biased onto the annular wall. The base unit includes a hollow spigot and an annular seal surrounding and spaced from the top of the spigot whereby insertion of the refill unit into the base unit causes the spigot to enter the annular wall and to lift the valve element from the annular wall to define a flow path from the refill unit, and the annular seal to seal between the spigot and the annular wall.
