The present invention relates to a static mixer 10 for mixing together at least two components. The static mixer 10 comprises- a mixer housing 12;- a mixing element 14 having an upstream end 16 with at least two entry openings 20 and a downstream end 18, the mixing element 14 being arranged at least partly within the mixer housing 12;- a mixing head 22 having at least two inlets 24 provided at an input side 26 and at least two outlets 28 provided at an output surface 30, wherein each of the at least two inlets 24 is in fluid communication with one of the at least two outlets 28; and- a separating wall 32 disposed between the output surface 30 and the upstream end 16 of the mixing element 14 for separating the components leaving the outlets 28. The separating wall 32 comprises a free downstream edge 33 which is disposed with respect to at least one of the entry openings 20 so as to allow at least partial flows of the components separated by the separating wall 32 to combine after exceeding the downstream edge 33 and to jointly enter said at least one of the entry openings 20.

The invention relates to a cartridge for at least two flowable components. The invention starts from a cartridge having at least two storage containers into which pistons can be inserted for dispensing components. So that the pistons cannot slip out of the storage containers again after the insertion, peripheral beads are provided at inner walls of the storage containers. To make possible cartridges which can be manufactured inexpensively and which can nevertheless be reliably sealed, it is proposed in accordance with the invention that the first inner wall has a first connection section and the second inner wall has a second connection section in which they do not have a bead. A connection web which connects the two storage containers is in this respect arranged between the first and second connection sections.

Syringe (10) for discharging two components comprises a housing (12)d, a piston (20) at least partly inside said housing and axially moveable relative thereto between a first and a second position, a hollow cylindrical container (22) at least partly inside said housing, surrounding said piston and axially moveable relative to said piston between a first and a second position, a first compartment (24) defined within said housing between the distal end of said piston assuming its first position and the distal end of said housing for receiving a first component (28), a second compartment (30) defined within said container assuming its first position between the proximal end of said container and the proximal end of said piston for receiving a second component (36), an axially extending passage (38) in the interior of said piston and in communication with said first compartment and a radial opening (40) of said piston in the region of the proximal end of said piston, sealing means (52) for preventing communication between said second compartment and said radial opening of said piston when the container assumes its first position, and releasable retaining means (44) for retaining said piston in its first position until said container has reached its second position. The syringe is further adapted so that communication between said second compartment and said radial opening of said piston is established after initiation of the movement of said container out of its first position towards its second position relative to said piston, thereby transferring said second component from said second compartment into the radial opening and through the axial passage of the piston into said first compartment, said retaining means are released by said container reaching its second position, and with the further movement of said container into said housing and the simultaneous movement of the released piston out of its first position towards its second position, the two mixed components are pressed out of said first compartment.
