Abstract: An apparatus for mixing at least two flowable components having a mixer housing with an outlet opening. At least one mixing element arranged in the mixer housing having at least two separate inlet passages through which the flowable components can be introduced separately from one another. Each inlet passage is capable of being in sealing cooperation with a respective outlet passage of a storage container or a chamber. At least one of the inlet passages has an end configured to cooperate with the outlet passage as a piercing element for opening a flow connection between the storage container or the chamber and the inlet passage. The piercing element includes at least two inflow areas for the flowable components, with the two inflow areas being inclined relative to one another. A dispensing apparatus having such a mixer is furthermore provided.

Abstract: A static spray mixer is proposed for the mixing and spraying of at least two flowable components, having a tubular, one-piece mixer housing (2) which extends in the direction of a longitudinal axis (A) up to a distal end (21) which has an outlet opening (22) for the components, having at least one mixing element (3) arranged in the mixer housing (2) for the mixing of the components as well as having an atomization sleeve (4) which has an inner surface which surrounds the mixer housing (2) in its end region, wherein the atomization sleeve (4) has an inlet (41) for a pressurized atomization medium. A plurality of grooves are provided in the outer surface of the mixer housing (2) or in the inner surface of the atomization sleeve (4) which respectively extend in the direction of the longitudinal axis (A) and through which the atomization medium can flow from the inlet (41) of the atomization sleeve (4) to the distal end (21) of the mixer housing (2).
