Abstract

A device for dispensing a multicomponent composition composed of a mixture of different fluid components includes a first and at least a second fluid component inlet. The device also includes a mixing area located downstream from the fluid component inlets and an outlet extending from the mixing area. Each of the fluid component inlets is adapted to communicate with a source of a different fluid component. The mixing area is adapted to receive a flow of a first and at least second fluid component. Within the mixing area, the flow of the first fluid component is disrupted to allow mixing with the flow of a second fluid component to form a flow of multicomponent composition. The mixing area is further adapted to disrupt the flow of the multicomponent composition before the flow of the multicomponent composition exits through the outlet.
