DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) FIG. 1 illustrates an application dispenser 1 configured as a cylindrical pin. This application dispenser includes a rotation element 2 on top, in particular configured as a ball in order to facilitate applying at least one component, for example for lipsticks or similar cosmetic articles that include two or more components. The rotation element 2 thus protrudes beyond a socket 2a which is applied to the housing 1a of the application dispenser 1. An adjustment device 1b configured as a turn button is provided at a bottom of the housing 1a wherein a volume ratio of the two components is adjustable by wedge elements (c.f. FIG. 1A and FIG. 1B). This adjustment device is described in more detail in the application DE 20 2012 006 466.5 of the applicant so that additional explanations can be omitted.

(7) The components are fed from schematically illustrated cartridges 1c (c.f. in particular FIG. 1B) to the rotation element 2 by a respective pump 3, wherein the two components (A and B) are transported separately through two feed channels 4. Additionally a plurality of outlet openings is arranged proximal to the rotation element 2 (c.f. FIG. 4), wherein the outlet openings for the component A are designated as 4a, whereas the outlet openings for the component B are designated with the reference numeral 4b. The outlet openings 4a, b that are offset from each other are thus divided by an intermediary wall 5.

(8) FIG. 1B illustrates the arrangement of the cartridges 1c or containers for the two components A and B and the two pumps 3. FIG. 2B illustrates the upper portion enlarged, wherein the component A is run through the central feed channel 4 within the intermediary wall 5, whereas the component B moves to an annular cavity 6 so that it exits under pressure at the rotation element 2 along an outside of the intermediary wall 5. The component A thus exits at a plurality of outlet openings 4a at an inside of the intermediary wall 5 and the component B exits at a respective number of outlet openings 4b at a radially outer side of the intermediary wall 5 (c.f. FIG. 4).

(9) This yields an intense mixing of the components directly at the rotation element 2. The divided feed channels 4a, 4b are enveloped by a central plug 8 or a ring 9 so that the two components can only exit along the fine individual channels directly onto the rotation element 2.

(10) FIG. 1A illustrates only one cartridge 1c and one pump 3 in a sectional view of the application dispenser 1 that is rotated by 90? relative to FIG. 1B. For this basic configuration with only one pump 3 for only one component the invention can be used as well since pressure loaded wetting of the rotation element 2 provides significant advantages for the response of the dispenser. In particular the material to be applied is provided with the actuation of the pump in the equator portion of the sphere 2 in order to be immediately applied by a slight rotation of the sphere 2.

(11) FIG. 2A illustrates the upper portion according to FIG. 1 in an enlarged manner, wherein the rotation element 2 is moved upward slightly through the pressure loading and thus forms an intermediary storage 7 below the ball. Thus, the gap is the largest at the lowest point, so that the product flow from the feed channels occurs in opposite directions for two components (c.f. FIG. 3). This additionally increases the mix effect together with the pressure loading.

(12) FIG. 2C illustrates a top view of the socket 2a without the rotation element 2. Thus, six ribs 2b are integrally formed in the interior (c.f. also the corresponding perspective in FIG. 2D) in order to form tight capillary gaps that are defined towards the spherical surface. This prevents overloading of the pump 3, wherein the minor exit of the pumped in components (?n) beyond the socket 2a, but adhering at the sphere even improves response properties.

(13) FIG. 3 illustrates a bottom element of the socket 2a separately, wherein the feed channels 4 for the two components are visible. The feed channels 4 for the components A, B can be produced integrally in one piece with the socket 2a, in particular as an injection molded component. The feed channels 4 can also include bars or subdivisions in order to further divide product flow which is indicated by arrows. It is thus essential that the product flow in a center of the intermediary storage device 7 occurs in opposite directions which increases mixing. This applies in particular for the embodiment with the intermediary wall 5 which is visible quite well in the perspective view in FIG. 4 in order to form the outlet openings 4a and 4b recited supra and in order to provide intensive mixing.
