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 hearing 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 dement (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 (1) with a pumping device (2), which has an actuating element (5) with a discharge opening (12), wherein

the actuating element (5) is displaceably arranged with respect to a bearing element (6), which is connected to a pump housing (7) in a rotationally fixed manner in the usage position, and the actuating element (5) is arranged such that it can rotate with respect to the bearing element (6),

characterised in that,

the bearing element (6) has at least one projecting land (25) with an upper stop edge (24), wherein

an essentially tubular section (5′

) of the actuating element (5) has on its inner surface, distributed over the circumference, at least two steps (22, 22′

, 22″

) defining different displacement travels, of which, in each case, depending on the direction of rotation of the actuating element (5), one step (22, 22′

, 22″

) in a lower displacement position strikes the stop edge (24).

2. The dispensing device in accordance with claim 1,

characterised in that,

a lower edge (23) of the tubular section (5′

) of the actuating element (5) in an upper inoperative position covers the upper stop edge (24) of the bearing element (6).

3. The dispensing device in accordance with claim 1,

characterised in that,

the steps (22, 22′

, 22″

) are immediately adjacent to each other circumferentially and define a stepped profile.

4. The dispensing device in accordance with claim 1,

characterised in that,

the width of the step (22, 22′

, 22″

) corresponds in each case to the width of the land (25) having the stop edge (24).

5. The dispensing device in accordance with claim 1,

characterised in that,

guide lands (27) extending in the displacement direction (5″

) are provided in an extension of the jump in level between two adjacent steps (22, 22′

, 22″

).

6. The dispensing device in accordance with claim 1,

characterised in that,

a blocking step (22) is designed such that, when aligned with the stop edge (24), the actuating element (5) is essentially blocked in its upper inoperative position.

7. The dispensing device in accordance with claim 1,

characterised in that,

a preferably circumferential flange-like projection (30) is provided in a lower end section of the actuating element (5).

8. The dispensing device in accordance with claim 1,

characterised in that,

a pull-off flap (18) is provided, which is connected to the bearing element (6) and blocks the displacement of the actuating element (5) from an upper inoperative position.

9. The dispensing device in accordance with claim 1,

characterised in that,

two diametrically arranged lands (25) are provided, together with a stop edge (24) and correspondingly diametrically configured steps (22, 22′

, 22″

).

10. The dispensing device in accordance with claim 1,

characterised in that,

the bearing element (6) is connected to the pump housing (7) by means of a screw connection (6″

, 7″

).

11. The dispensing device in accordance with claim 1,

characterised in that,

the discharge opening (12) of the actuating element (5) is provided with a protective cap (13), which has a slot-shaped valve (14).

12. The dispensing device in accordance with claim 11,

characterised in that,

the protective cap (13) has a circumferential bead (15), which is accommodated in a detent groove (16) of the actuating element (5) arranged adjacent to the discharge opening (12).

13. The dispensing device in accordance with claim 11,

characterised in that,

the protective cap (13) consists of a thermoplastic elastomer (TPE), preferably of a thermoplastic vulcanisate (TPV), in particular of ethylene-propylene-diene-monomer rubber particles (EPDM) in a matrix of polypropylene, or silicone.

14. The dispensing device in accordance with claim 1,

characterised in that,

the actuating element (5) is connected to a piston rod (10), which is moved together with the actuating element (5), preferably against the restoring force of an elastic spring element (10″

), wherein

a valve element (10) is accommodated in the actuating element (5), and the piston rod (10) is displaceably accommodated in the pump housing (7), which is provided at one end with a one-way valve (9), preferably a ball valve.

15. The dispensing device in accordance with claim 1,

characterised in that,

the pump housing (7) is accommodated in a riser sleeve (18′

″

), in which a riser tube (8) is accommodated, which is communicatively connected to the one-way valve (9).

16. The dispensing device in accordance with claim 1,

characterised in that,

the pumping device (2) is connected to the interior (4′

) of a container (4) and is connected to the container (4) by means of a lid (3), wherein

the container (4) preferably accommodates a displaceably mounted overrun sleeve (17), which is connected in an essentially sealed manner to the riser sleeve (18′
