Device for application of a cosmetic powder to a sponge

1. A device for application of a cosmetic powder to a sponge comprising:

a housing;

a receiving shell to accommodate the sponge, said receiving shell being accessible from outside;

a powder reservoir disposed in the housing for storage of the powder before application; and

a transport device;

wherein the transport device is formed to transport the powder from the powder reservoir to the receiving shell, said transport device being designed to generate an air stream, wherein a flow path of said air stream runs along the powder reservoir to take up powder and then enters the receiving shell;

wherein the transport device has a pressure chamber with a variable volume for pressurization of air, wherein an outlet valve assembly is assigned to said pressure chamber; and

wherein the outlet valve assembly is formed so that the outlet valve assembly opens at a pre-determined minimum positive pressure in the pressure chamber.

2. The device according to claim 1 , wherein the outlet valve assembly has an elastic variable-shape outlet valve which opens through elastic deformation depending on pressure.

3. The device according to claim 1 , wherein the outlet valve assembly has a valve seat and a valve body, said valve body being pressed through force of a spring against the valve seat, wherein an ejector is provided that is formed and arranged such that from a pre-determined reduction in a volume of the pressure chamber, the ejector separates the valve body from the valve seat to initiate the air stream.

4. The device according to claim 1 , wherein the transport device can be actuated through relative displacement of two housing parts, wherein a first housing part forms a base of the device and a second housing part is arranged in a fixed position relative to the receiving shell.

5. A device for application of a cosmetic powder to a sponge comprising:

a housing;

a receiving shell to accommodate the sponge, said receiving shell being accessible from outside;

a powder reservoir disposed in the housing for storage of the powder before application; and

a transport device;

wherein the transport device is formed to transport the powder from the powder reservoir to the receiving shell, said transport device being designed to generate an air stream, wherein a flow path of said air stream runs along the powder reservoir to take up powder and then enters the receiving shell; and

wherein the flow path of the air stream runs through a mixing channel which lies next to the powder reservoir, wherein at least one opening is provided in a wall of the mixing channel, said at least one opening connecting an inner region of the mixing channel to the powder reservoir.

6. The device according to claim 5 , wherein the powder reservoir is formed such that the powder is arranged in the powder reservoir because of a weight of the powder such that the powder lies at least in part against an outer wall of the mixing channel.

7. The device according to claim 1 , wherein the receiving shell is formed to accommodate a flat sponge.

8. The device according to claim 1 , wherein the receiving shell is connected through a plurality of openings in a base area of the receiving shell to the transport device.

9. The device according to claim 8 , wherein the plurality of openings are formed such that the plurality of openings reproduce a shape of at least one alphanumeric symbol or trademark logo.

10. A device for application of a cosmetic powder to a sponge comprising:

a housing;

a receiving shell to accommodate the sponge, said receiving shell being accessible from outside;

a powder reservoir disposed in the housing for storage of the powder before application; and

a transport device;

wherein the transport device is formed to transport the powder from the powder reservoir to the receiving shell, said transport device being designed to generate an air stream, wherein a flow path of said air stream runs along the powder reservoir to take up powder and then enters the receiving shell;

wherein the receiving shell is connected through a plurality of openings in a base area of the receiving shell to the transport device;

wherein the transport device has a distribution device through which the air stream is split into a plurality of partial air streams which pass through different openings in the receiving shell; and

wherein the distribution device has an inlet and a splitting body that is arranged in alignment with said inlet and which tapers conically in a direction of said inlet.

11. The device according to claim 1 , wherein a lid is provided which can be placed on the housing such that the receiving shell can be closed by the lid.

12. The device according to claim 1 , wherein the receiving shell is formed so that the receiving shell is removable.

13. The device according to claim 1 , wherein the minimum positive pressure is 0.4 bar.

14. The device according to claim 7 , wherein said receiving shell has a maximum height of 15 mm and a minimum base area of 30 mm×30 mm and wherein a removable flat sponge is disposed in the receiving shell and has a maximum thickness of 15 mm and a minimum base area of 20 mm×20 mm.

15. The device according to claim 8 , wherein the openings are distributed over at least 25% of the base area of the receiving shell.

16. The device according to claim 10 , wherein the openings are distributed over at least 25% of the base area of the receiving shell.

17. The device according to claim 12 , wherein the receiving shell, when in an inserted position, serves as a cover for the powder reservoir and after removal permits refilling of the powder reservoir.
