Abstract

A cartridge for dispensing a two-component mass is formed by two interconnected containers to that different combinations of the components are provided along with different mixture ratios. Initially, the containers are separate with partitions located in their interconnecting regions. The partitions can be removed either before or after the containers are connected together. After removal of the partitions, the components of the mass can be mixed. Following the mixing operation, a piston within the cartridge can press out or dispense the mass through an outlet nozzle formed on one of the containers.

Claims

1. Cartridge for a two-component mass comprises a first axially extending container holding one component of the mass and a second axially extending container holding the other component of the mass, said first and second containers each having a first end and a second end and being connectable together at the first ends thereof in axial alignment, wherein the improvement comprises that each of said first and second containers has a connecting region at the first ends thereof where said containers are connectable together, each connecting region has a removable partition forming a sealed closure before said containers are connected together, so that upon removal of the partitions from the connecting region, the contents of the first and second containers can be intermixed, one of said removable partitions is a mechanically detachable sealing cap, the other said removable partition is an axially displaceable piston displaceable within and in the axial direction of the container in which it is positioned away from the other container, whereby the components of the mass can be intermixed, said container in which said piston is located has an inside surface, said displaceable piston is a cup-shaped sealing disc with an annular deformable sealing lip projecting from said sealing disc toward the first end of the container in which the piston is located and disposed in contact with the inside surface of said container so that as said piston is displaced in the direction toward the second end of said container in which it is positioned, said lip deflects whereby the component within the container can flow around said piston into the component in the other said container.
