Abstract
A coaxial cartridge for multi-component materials includes a head part having an outlet, an inner tube forming a first storage compartment configured to store a first component inner tube forms part of the outlet, and an outer tube. The inner tube is arranged within the outer tube at a longitudinal axis that is common to both the inner tube and the outer tube. A space formed between the outer tube and the inner tube forms a second storage compartment configured to store a second component. The outer tube forms a further part of the outlet.
Claims19
A coaxial cartridge for multi-component materials, the coaxial cartridge comprising:
- a head part having an outlet;
- an inner tube having a space therein, the space forming a first storage compartment configured to store a first component, a part of the inner tube forming a part of the outlet;
- an outer tube, the inner tube arranged within the outer tube at a longitudinal axis of the coaxial cartridge, with the longitudinal axis being common to both the inner tube and the outer tube, a space formed between the outer tube and the inner tube forming a second storage compartment configured to store a second component, and a part of the outer tube forms a further part of the outlet, the inner tube connected to the outer tube at first and second points of connection present at the head part, with the first and second points of connection being arranged at different positions at the head part, with the different positions being arranged spaced apart at different distances from the longitudinal axis, and the first point of connection formed at the outlet;
- and
- a seal member disposed between the inner tube and the outer tube at the head part, the seal member surrounding the second point of connection.
