A fluid dispenser for dispensing a metered volume of a fluid product having a storage chamber for storing the fluid product in; a dispensing outlet through which the fluid product is dispensable from the dispenser; a metering chamber which is adapted to provide the metered volume of the fluid product for dispensing through the dispensing outlet by movement of the metering chamber between a contracted state and an expanded state, movement of the metering chamber from the contracted state to the expanded state placing the metering and storage chambers in fluid communication to enable the metering chamber to receive from the storage chamber an excess volume of the fluid product comprising the metered volume and a surplus volume; and a bleed arrangement adapted to bleed the surplus volume of the fluid product from the metering chamber is described.
