ABSTRACT:
A dispenser includes a first container (12) for containing a component C and a cavity (30) for receiving a separate cartridge (60). A first piston (34) is received in the container (12) and a second piston (78) is received in the cartridge (60). A blade (48) extends between the piston (34) and piston (78) for slicing the separate cartridge (60) as the pistons move so that the component C and a second component C1 in the separate cartridge (60) are expelled from the dispenser. A valve arrangement (100) can be coupled to an outlet (18) for the dispenser in order to dispense the components C and C1 and a flexible sleeve (50) may be arranged in the container (12) between a sidewall of the container (12) and the piston (34) for sealing any space between the piston (34) and the sidewall of the container (12).
