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.

Abstract: A dispensing device for a multi-component composition comprises a plurality of collapsible bag compartments (109, 110) located within a housing (101). The compartments extend adjacent each other and have cross-sectional areas that are proportional to an intended volume mixing ratio for the multi-component composition. Each compartment has an opening (123) that communicates with a device outlet at one end of the housing, and an opposite, sealed end that is exposed to pressure from a compression device (103). The compression device acts to collapse the compartments and dispenses the components through the device outlet. The components have different viscosities. The chamber of a less viscous component has a flow control regulator (111) to compensate for extra pressure exerted on that compartment by an adjacent compartment containing a more viscous component.
