Abstract: A mixer includes a mixer housing, a mixing element and a mixer inlet section having at least two inlets at an input side and at least two outlets at an output side. The outlets are in fluid communication with the mixing element. The inlets are sealingly connected to corresponding exit openings of a cartridge. The mixer housing includes a connection device for connecting the mixer to the cartridge by rotational movement around a longitudinal axis. An engagement element is disposed at an outer surface of the mixer housing which is accessible from the outside when the mixer is connected to the cartridge. The engagement element includes an engagement surface spaced apart from the upstream end of the mixer housing in the direction of the longitudinal axis. The engagement surface points in the direction of the upstream end of the mixer housing thereby forming an undercut.

Abstract: The invention relates to an applicator, and in particular a cosmetic applicator (1), for applying a cosmetic to the skin, comprising an applicator element and a handle (5) or handle attachment (5a, 5b, 5c), wherein the applicator element is an applicator blade (2) having two main surfaces (3, 4), wherein the handle (5) or handle attachment (5a, 5b, 5c) extends from one of the main surfaces (4) of the applicator blade and the applicator blade (2) protrudes beyond the handle or handle attachment on at least three sides, better on all sides, and the distal main surface (3) of the applicator blade (2) spans a plane (E) that forms an acute angle (W) of at least 20°, or greater, with the longitudinal axis L of the handle (5) or handle attachment (5a, 5b, 5c).

Abstract: A multicomponent cartridge includes a first storage chamber for a first component and a second storage chamber for a second component. The first storage chamber is separate from, and arranged next to, the second storage chamber. A first piston is movably received in the first storage chamber. A second piston is movably received in the second storage chamber. Each of the first or second storage chambers has a respective filling end and a respective discharge end. The storage chambers are connected to one another at at least the discharge end. The storage chambers have inner walls with the discharge end opening into a discharge element in an opening aperture. A venting element is upstream of the corresponding opening aperture at at least one of the inner walls, with the venting element extending over a maximum of one third of a longitudinal dimension of the storage chamber.
