Abstract
A dispensing device for a multi-component composition comprising a housing (1) in the form of an elongate sleeve. The housing has a first end for receiving a compression device (3) and a second end defining an outlet (7) from which a supply of components housed within the housing are dispensed. Each component is retained within a compartment (21, 22) of a collapsible bag (2; 9, 10) prior to being dispensed. The collapsible bag compartments each have a sealed end for receiving pressure from the compression device and a dispensing end for dispensing a component via an outlet (23). The dispensing device is provided with a closure device (4) through which the dispensing ends of the collapsible bag compartments extend. The closure device (4) is adapted to apply a clamping force on the dispensing ends to seal off the supply of the components and to release the clamping force when required to allow the components to be dispensed.
