Claims
- 1. An implement for applying a fluid, comprising:a sleeve-like shank having a container, said container having: an interior accommodating a fluid; a front end; a rear end, said front end and said rear end each fluidically connected to the atmosphere for admitting air into and extracting air from said interior; and at least one air-admission opening disposed at said rear end of said container and opening said interior to the atmosphere; a diaphragm permeable to air and impermeable to the fluid, said diaphragm closing off said at least one air-admission opening; a writing tip of a capillary material, said tip connected to said shank; and a fluid-directing system fluidically connecting said writing tip to the fluid in said interior with said capillary material, said fluid-directing system directing fluid from said interior of said container to said writing tip.
- 2. The implement according to claim 1, including a second diaphragm permeable to air and impermeable to the fluid, said at least one air-admission opening including an air-admission opening at said front end, and said air-admission opening at said front end being closed off by said second diaphragm.
- 3. The implement according to claim 2, wherein:said container has a container wall with an inside surface and an outside surface; and said diaphragm and said second diaphragm are each disposed on one of the group consisting of said outside surface and said inside surface.
- 4. The implement according to claim 2, wherein said container is made by injection molding with at least one of said diaphragm and said second diaphragm molded therein.
- 5. The implement according to claim 1, wherein said container is made by injection molding with said diaphragm molded therein.
- 6. The implement according to claim 1, wherein said fluid-directing system has:a tube with a substantially radially projecting flange; and said flange forms a front end wall of said container.
- 7. The implement according to claim 6, wherein said tube, said flange, and said container are integral.
- 8. The implement according to claim 6, wherein said tube, said flange, and said container are formed in one piece.
- 9. The implement according to claim 1, wherein:said container has a circumferential wall; and said shank forms said circumferential wall of said container.
- 10. The implement according to claim 9, wherein:said shank has a rear end and an outside; a stopper has an inside and closes off said rear end of said shank; and an air-admission channel fluidically communicating with the atmosphere is disposed between said inside of said stopper and said outside of said shank.
- 11. The implement according to claim 1, wherein said container is separate from said shank and is disposed in said shank.
- 12. The implement according to claim 11, wherein:said container has an outer surface; said shank has an inner surface; said at least one air-admission opening is at least one rear air-admission opening; and an air channel is disposed between said outer surface of said container and said inner surface of said shank and fluidically communicates with said at least one rear air-admission opening.
- 13. The implement according to claim 12, wherein:said fluid-directing system has a tube; a substantially sleeve-like tip part: encloses said tube at a radial spacing therefrom; defines a cavity; and defines an air channel fluidically connected to the atmosphere and open to said cavity; said cavity fluidically communicates with the atmosphere through said air channel; and said air channel is disposed between said tube and said tip part.
- 14. The implement according to claim 12, wherein:said container has a circumferential wall; and said at least one air-admission opening includes an air-admission opening disposed in said circumferential wall of said container.
- 15. The implement according to claim 14, wherein said air-admission opening in said circumferential wall of said container is at least one elongate air-admission opening extending from said front end of said container to said rear end of said container.
- 16. The implement according to claim 11, wherein said container is an exchangeable cartridge.
- 17. The implement according to claim 16, wherein:said cartridge has a front end wall defining a central opening; said fluid-directing system has a tube with a rear end; and said rear end of said tube is inserted releaseably into said central opening.
- 18. The implement according to claim 1, wherein:said fluid-directing system has a tube with an interior having an inner cross-section; said writing tip has a rear longitudinal section disposed in said tube; an insert is disposed in said interior of said tube and narrows said inner cross-section to form at least one longitudinally extending fluid channel in said interior of said tube; and said fluid channel adjoins said writing tip and fluidically communicates with the atmosphere for admitting air into and extracting air from said front end of said container.
- 19. The implement according to claim 18, wherein:said tube has an inner tube wall; said insert has: a circumferential section abutting said inner tube wall; and at least one flattened portion disposed at a distance from said inner tube wall; and said inner tube wall and said flattened portion define said fluid channel.
- 20. The implement according to claim 19, wherein said fluid channel has a cross-sectional surface area decreasing in a direction of said container.
- 21. A stick-like writing implement for applying a fluid, comprising:a sleeve-like shank having a container, said container having: an interior accommodating a fluid; a front end; a rear end; said front end and said rear end each fluidically connected to the atmosphere for admitting air into and extracting air from said interior; and at least one air-admission opening disposed at said rear end and fluidically connecting said interior to the atmosphere; a diaphragm permeable to air and impermeable to the fluid, said diaphragm closing off said at least one air-admission opening; a writing tip of a capillary material, said tip connected to said shank; and a fluid-directing system fluidically connecting said writing tip to the fluid in said interior with said capillary material, said fluid-directing system directing fluid from said interior of said container to said writing tip.
- 22. A stick-like cosmetics implement for applying a fluid, comprising:a sleeve-like shank having a container, said container having: an interior accommodating a fluid; a front end; a rear end; said front end and said rear end each fluidically connected to the atmosphere for admitting air into and extracting air from said interior; and at least one air-admission opening disposed at said rear end and fluidically connecting said interior to the atmosphere; a diaphragm permeable to air and impermeable to the fluid, said diaphragm closing off said at least one air-admission opening; a writing tip of a capillary material, said tip connected to said shank; and a fluid-directing system fluidically connecting said writing tip to the fluid in said interior with said capillary material, said fluid-directing system directing fluid from said interior of said container to said writing tip.
