Abstract
A syringe for multi-component materials includes a mixer housing, a mixing element, a multi-component cartridge and a mixing head, the mixing head being arranged at least partly within the mixer housing and adjacent to the multi-component cartridge. The mixing head is arranged moveable in an axial direction of the syringe between at least two positions, the at least two positions including a sealed position and a dispensing position. The axial movement of the mixing head is brought about by rotation of at least a part of the mixer housing relative to the multi-component cartridge. The mixing head is axially displaced in a direction opposite to a dispensing direction on a displacement of the mixing head from the sealed position into the dispensing position.
