Abstract:
1. A cartridge comprising: a. two tubes disposed parallel to one another, having a common outlet nozzle with an outlet opening; b. a closure piston disposed in said outlet nozzle, said closure piston having at least one passage opening; and c. in each of the tubes one dispensing piston, said dispensing pistons adjustable via a common dual piston rod; wherein said closure piston and said dispensing pistons are respectively disposed to form a seal and to be displaceable and spaced apart from one another so as to form chambers between said dispensing pistons and said closure piston for accommodating substances in paste form or capable of flow, which substances intermix with each other downstream of said closure piston; wherein said closure piston is displaceable in a direction towards said outlet opening by means of the pressure that said substances accommodated in said chambers transfer from the dispensing pistons, wherein said closure piston is displaceable between a closure position wherein said chambers are closed and a dispensing position wherein said chambers have a flow connection with said outlet opening via said passage opening; and wherein a mixing tube is settable onto the outlet nozzle.
