Dispensing device
Disclosed is a device ( 1 ) for dispensing a liquid ( 2 ) without spraying as well as a use of such a dispensing device ( 1 ). In order to prevent liquid from escaping after a dispensing process, an outlet that opens towards the environment can be closed by means of a discharge valve ( 7 ). Said discharge valve ( 7 ) is provided with a valve body ( 9 ) which can be moved in accordance with the prevailing liquid pressure such that the discharge valve ( 7 ) opens when a minimum pressure is exceeded.
1. Dispensing device for the non-spraying dispensing of a liquid, with an outlet channel and an associated outlet valve, wherein
the outlet channel has an outlet opening which opens to the outside or is arranged downstream and can be sealed by the outlet valve, and wherein
the outlet valve has a valve body which can be moved in a manner dependent on the corresponding liquid pressure, so that the outlet valve opens upon overshooting of a minimum pressure, wherein
the valve body is held by means of an elastically deformable retention section, and wherein, upon opening the outlet valve, the valve body retreats into the outlet opening or into a section of the outlet channel adjacent upstream of the outlet opening.
2. Dispensing device as set forth in claim 1 , wherein the dispensing device is embodied as a dispensing head or has a dispensing head.
3. Dispensing device as set forth in claim 1 , wherein the dispensing device is or can be connected to a reservoir or container that is or can be pressurized, with the liquid or is provided therewith.
4. Dispensing device as set forth in claim 1 , wherein the dispensing device is connected to a dispensing valve, which can be opened by pressing.
5. Dispensing device as set forth in claim 1 , wherein the dispensing device is or can be connected to a manually operable pump for conveying the liquid or is provided with the manually operable pump.
6. Dispensing device as set forth in claim 5 , wherein the pump is operated through depression.
7. Dispensing device as set forth in claim 1 , wherein the liquid is dispensed as a foam or a shaving foam.
8. Dispensing device as set forth in claim 1 , wherein the minimum pressure of the outlet valve is higher than a foaming pressure of a self-foaming liquid.
9. Dispensing device as set forth in claim 1 , wherein the dispensing device has an upper part with the valve body, with the upper part being embodied in a single piece or being manufactured by means of bi-injection.
10. Dispensing device as set forth in claim 1 , wherein, when the outlet valve is closed, the valve body ends at least substantially at the level of the outlet opening.
11. Dispensing device as set forth in claim 1 , wherein the valve body protrudes over the outlet opening toward the outside.
12. Dispensing device as set forth in claim 1 , wherein the outlet opening or a section of the outlet channel adjacent thereto forms a valve seat of the outlet valve or for the valve body.
13. Dispensing device as set forth in claim 1 , wherein the valve body is substantially cylindrical.
14. Dispensing device as set forth in claim 1 , wherein the valve body has a ring collar or a substantially conical sealing section, which acts in a sealing manner together with a valve seat of the outlet valve when the outlet valve is closed.
15. Dispensing device as set forth in claim 1 , wherein the valve body is made of elastic material.
16. Dispensing device as set forth in claim 1 , wherein the valve body is injection molded.
17. Dispensing device as set forth in claim 1 , wherein the valve body is embodied in a single piece with the retention section or is formed thereon.
18. Dispensing device as set forth in claim 1 , wherein the valve body is held by means of the retention section and is injection molded together in one piece with the valve body and with a mounting section formed onto a component of the dispensing device.
19. Dispensing device as set force in claim 13 , wherein the valve body is moveable along its longitudinal axis in the outlet channel.
20. Dispensing device as set force in claim 1 , wherein the retention section is annular.
21. Dispensing device as set force in claim 1 , wherein the retention section forms an elastically deflectable membrane.
22. Dispensing device as set force in claim 13 , wherein the retention section extends in radial direction of the valve body.
