Syringe for multi-component materials, method of activating a syringe, mixing and dispensing apparatus and multi-component cartridge

A syringe, comprising:

• a mixer housing;
• a mixing element;
• a multi-component cartridge;
• a mixing head separate from the mixer housing, the mixing head being arranged at least partly within the mixer housing and adjacent to the multi-component cartridge, and arranged to be moveable in an axial direction of the syringe between at least two positions, the at least two positions comprising a sealed position and a dispensing position, the movement in the axial direction of the mixing head being brought about by a rotation of at least a part of the mixer housing relative to the multi-component cartridge, and the mixing head being axially displaced in a direction opposite to a dispensing direction on displacement of the mixing head from the sealed position into the dispensing position, the syringe configured to be activated upon displacement of the mixing head from the sealed position to the dispensing position by the rotation of the at least a part of the mixer housing relative to the multi-component cartridge and with at least a part of a base of the mixing head being a seal and being configured to seal outlets of the multi-component cartridge when the mixing head is in the sealed position;
• and
• a guide portion having at least one guide slot associated with the multi-component cartridge, the guide portion being fixedly connected to or integrally formed with the multi-component cartridge, and the mixer housing includes at least one cam cooperating with the at least one guide slot to facilitate rotational movement or the movement in the axial direction between the sealed position and the dispensing position.
