ABSTRACT:
A dispenser for dispensing two components is disclosed which comprises a drum 10 in which a tube 20 is supported. A first piston 12 is arranged within the drum 10 and has an opening 22 through which the tube 20 extends. The opening is provided with a plug 80 which has an aperture also through which the tube 20 extends. The plug supports a blade 32 which bears on a second piston 40 arranged within the tube 22. The plug 80 is fixed relative to the piston 12 so that it and the blade 32 move with the piston 12. During movement of the piston 12 the blade 32 slices the tube 20 and bears against the second piston 40 so that the first piston 12 and the second piston 40 move in a fixed manner as a single unit. During movement of the pistons 12 and 40 the two components are dispensed from the drum 10 and the tube 22 in a particular ratio depended upon the volume displaced by movement of the pistons 12 and 40. The dispensed components can therefore be mixed together in the predetermined ratios.
