Device for injecting a filling material in the fluid phase into a canal space, the device including an adaptor nozzle connected to an auto-mixer, and an injection tip fitted at the upper end of the auto-mixer. At a distal end the injection tip has an outside diameter of 1.5 mm or less over a length of 8 mm or greater. The injection tip is made of memory shape material for bending to a desired orientation. The injection tip is molded to the upper end of the auto-mixer, and on an exterior surface of the injector tip are either circular ribs defining a groove, the upper end of the auto-mixer being molded into the groove so the injection tip is locked in position in the upper end while retaining a degree of freedom to rotate about its axis of symmetry, or one or more mutually parallel circular ribs, and the upper end of the auto-mixer is molded onto the circular rib so the injection tip is blocked in position in the upper end while retaining a degree of freedom to rotate about its axis of symmetry.

A dispenser assembly includes a rod, a plunger and a stopper. The rod has a plunger receiving end with a clip receiving recess. The plunger has a rod receiving structure with a rod engaging clip biased to fit to the clip receiving recess of the rod for movement therewith. The stopper has a plunger receiving space that defines an aperture extending through the plunger receiving space with the rod extending through the aperture. The plunger receiving space is dimensioned such that with the rod receiving structure of the plunger located within the plunger receiving space, movement of the rod engaging clip is restricted by contact with surfaces of the plunger receiving space preventing release of the rod from the plunger.

A mixer assembly with a static mixing element arranged within a mixing channel. The mixer assembly has an inlet end, for receiving components of a substance and a dispensing end for dispensing a mixture from the components. The inlet end comprises for each component an inlet and an associated non-return valve. Each of the inlets is connectable for fluid communication with the mixing channel via the associated non-return valve.

The invention relates to a mixing capsule (1) comprising a first chamber (2) to receive a composition A and a second chamber (3) to receive a composition B, characterised in that the first chamber (2) and the second chamber (3) are arranged rotatably about the longitudinal axis (5) of the mixing capsule (1), the first chamber (2) comprising a first opening (25), the second chamber (3) comprising a second opening (26), the first opening (25) and the second opening (26) being arranged perpendicularly to the longitudinal axis (5) and plan-parallelly to each other and/or perpendicularly spaced, the first opening (25) and the second opening (26) being arranged incongruently to each other in a storage position (4), the first opening (25) and the second opening (26) being arranged congruently to each other in a handling position (6). Furthermore, the invention relates to a method for mixing at least two compositions A and B to a composition C in a mixing capsule and to a use of the mixing capsule.
