Multi-component dispenser

A re-sealable and re-useable dispensing device for a multi-component composition, the dispensing device comprising a housing generally in the form of an elongate sleeve having a first end for receiving a compression device and a second end defining shoulders that taper to an outlet from which a supply of components housed within the housing are to be dispensed, wherein each component is retained within a compartment of a collapsible bag prior to being dispensed, the collapsible bag compartments each having a sealed end for receiving pressure from the compression device and a dispensing end, which has been ruptured or is capable of rupturing, for dispensing a component via the outlet, wherein the dispensing device is provided with a closure device that the dispensing ends of the collapsible bag compartments are arranged to extend through, the closure device being adapted to apply a clamping force on the dispensing ends to seal off, or to re-seal, the supply of the components until the next use and to release the clamping force when required to allow the components to be dispensed, wherein the closure device comprises a plurality of fingers that are arranged in a ring extending around an aperture to clamp off the dispensing ends of the collapsible bag compartments, and wherein the closure device cooperates with a rotatable member in the form of a cap, which is turned from a first position to a second position to open and close off the closure device, and wherein the cap screws onto an external screw thread provided on an external surface of a neck region, the cap being unscrewed and replaced with a dispensing nozzle prior dispensing the components.
