Abstract
A dispenser for dispensing a metered volume of a fluid product having a storage chamber for storing the fluid product, an outlet orifice through which the fluid product is dispensable from the dispenser and a metering chamber is disclosed. The metering chamber has an outlet opening which places the metering chamber in fluid communication with the outlet orifice, a transfer opening through which the fluid product is transferable between the storage and metering chambers, and a boundary wall structure which is cyclically movable between a first configuration, in which the transfer opening is opened, and a second configuration, in which the transfer opening is closed. Each cycle of movement which commences at, and ends in, the second configuration results in a metered volume of the fluid product being transferred from the storage chamber to the metering chamber via the transfer opening and dispensed from the outlet orifice via the outlet opening. The dispenser further has an actuation mechanism actuable by a user of the dispenser to cause a cycle of movement of the boundary wall structure. The actuation mechanism is adapted so as to dispose the boundary wall structure in the second configuration at the end of each cycle of movement caused thereby.
