Abstract
An assembly for packaging and dispensing liquid may include a receptacle for containing a supply of liquid and a refillable unit arranged to be placed in a separable manner on the receptacle. The refillable unit may include a body and a piston that is movable relative to the body and that co-operates therewith to define a storage chamber of variable volume for containing the liquid. The storage chamber may be put into fluid communication with the receptacle to be filled therefrom when the refillable unit is placed on the receptacle. The refillable unit may also include a pump arranged to take liquid from the receptacle when the refillable unit is placed thereon, and to take liquid from the storage chamber when the refillable unit is separate from the receptacle. The pump may include a pump chamber that is distinct from the storage chamber.
