A device for dispensing a liquid or creamy product from a container comprises a valve housing 17, which has a continuous passage running in a generally vertical direction, comprising an upper inlet part 18a intended for connection to a container 10, an outlet part 18b and an intermediate valve chamber 18c, which is delimited by two elastic disc-like valve elements 19, 20 situated at a mutual distance apart in the longitudinal direction of the passage, which valve elements have thickened hub sections 19a, 20a, by means of which they are mounted on a journal 21 disposed centrally within the valve chamber. In order to make the device easier and cheaper to produce, the journal 21 is constructed in one piece with the wholly integral valve housing 17, whereupon it extends upwards and into the valve chamber 18c from a partial bottom wall 22, which partially closes off the valve housing 17 in the downward direction but on one side of the journal 21 leaves a free opening 23 which emerges in an outlet duct 24 disposed in a part 25 of the valve housing 17 projecting downwards from the said bottom wall 22. The journal 21 supports, close to its lower end, a collar 21b, on which the hub section 19a of the lower valve element 19 rests. The hub section 20a of the upper valve element 20 is held in bearing contact against the hub section 19a of the valve element 19 by a stop member 26, which is arranged in axially fixed position in the inlet part 18a of the passage 18 above the upper valve element 20. <IMAGE> |
