Abstract

The invention relates to a dispensing device (1) having a pump device (2), which has an actuating element (5) having an output opening (12), wherein the actuating element (5) is movably arranged relative to a bearing element (6), which is connected to a pump housing (7) in a rotationally fixed manner in the usage position, wherein the actuating element (5) is rotatably arranged relative to the bearing element (6) and the bearing element (6) has at least one protruding bridge (25) having an upper stop edge (24) and a substantially tubular portion (5′) of the actuating element (5) has, on the inner surface thereof, distributed over the circumference, at least two stages (22, 22′, 22″) defining a different displacement path, of which stages, depending on the rotational alignment of the actuating element (5), one stage (22, 22′, 22″) contacts the stop edge (24) in a lower displacement position.

Claims

1. A dispensing device comprising:

a pumping device, which has an actuating element with a discharge opening, the actuating element being displaceably arranged with respect to a bearing element,

the bearing element being connected to a pump housing in a rotationally fixed manner in a usage position, and the actuating element being arranged such that it can rotate with respect to the bearing element,

the bearing element has at least one projecting land with an upper stop edge, and

an essentially tubular section of the actuating element has, extending inwardly from an inner surface, distributed over the circumference, at least two steps defining different displacement travels, of which, in each case, depending on the direction of rotation of the actuating element, one step in a lower displacement position strikes the upper stop edge.

2. The dispensing device in accordance with claim 1,

wherein a lower edge of the tubular section of the actuating element in an upper inoperative position covers the upper stop edge of the bearing element.

3. The dispensing device in accordance with claim 1,

wherein the steps are immediately adjacent to each other circumferentially and define a stepped profile.

4. The dispensing device in accordance with claim 1,

wherein a width of the step corresponds in each case to a width of the land having the upper stop edge.

5. The dispensing device in accordance with claim 1,

wherein guide lands extending in the displacement direction are provided in an extension of a jump in level between two adjacent steps.

6. The dispensing device in accordance with claim 1,

wherein a blocking step is designed such that, when aligned with the upper stop edge, the actuating element is essentially blocked in its upper inoperative position.

7. The dispensing device in accordance with claim 1,

wherein a flange-like projection is provided in a lower end section of the actuating element.

8. The dispensing device in accordance with claim 7, wherein the flange-like projection is a circumferential flange-like projection.

9. The dispensing device in accordance with claim 1,

wherein a pull-off flap is provided, which is connected to the bearing element and blocks the displacement of the actuating element from an upper inoperative position.

10. The dispensing device in accordance with claim 1,

wherein two diametrically arranged lands are provided, together with the upper stop edge and correspondingly diametrically configured steps.

11. The dispensing device in accordance with claim 1,

wherein the bearing element is connected to the pump housing by a screw connection.

12. The dispensing device in accordance with claim 1,

wherein the discharge opening of the actuating element is provided with a protective cap, which has a slot-shaped valve.

13. The dispensing device in accordance with claim 12,

wherein the protective cap has a circumferential bead, which is accommodated in a detent groove of the actuating element arranged adjacent to the discharge opening.

14. The dispensing device in accordance with claim 12,

wherein the protective cap consists of a thermoplastic elastomer (TPE) or silicone.

15. The dispensing device in accordance with claim 14, wherein the protective cap consists of a thermoplastic vulcanisate (TPV).

16. The dispensing device in accordance with claim 15, wherein the thermoplastic vulcanisate comprises ethylene-propylene-diene-monomer rubber particles (EPDM) in a matrix of polypropylene.

17. The dispensing device in accordance with claim 1,

wherein the actuating element is connected to a piston rod, which is moved together with the actuating element, and

wherein a valve element is accommodated in the actuating element, and the piston rod is displaceably accommodated in the pump housing, which is provided at one end with a one-way valve.

18. The dispensing device in accordance with claim 17, wherein the piston rod is moved together with the actuating element against the restoring force of an elastic spring element.

19. The dispensing device in accordance with claim 17, wherein the one-way valve comprises a ball valve.

20. The dispensing device in accordance with claim 1,

wherein the pump housing is accommodated in a riser sleeve, in which a riser tube is accommodated, which is communicatively connected to the one-way valve.

21. The dispensing device in accordance with claim 20,

wherein the pumping device is connected to the interior of a container and is connected to the container by a lid.

22. The dispensing device in accordance with claim 21, wherein the piston rod wherein the container accommodates a displaceably mounted overrun sleeve, which is connected in an essentially sealed manner to the riser sleeve and to the container.

23. The dispensing device in accordance with claim 22,

wherein the overrun sleeve has a circumferential sealing lip, which widens conically upwards in a direction of the lid.

24. The dispensing device in accordance with claim 23, wherein the overrun sleeve has a circumferential a single sealing lip, which widens conically upwards in the direction of the lid.
