The invention relates to a dispenser for powdery Substances on its housing - possibly with the interposition of a removable one Socket - a container open to the housing for the substance can be attached, with a one Outlet opening at the bottom of the housing and a discharge opening in a plate above the housing bottom penetrating, notched on its circumference, displaceable between two end positions Piston valve which is held by a guide arranged above the plate.

In a known dispenser, the storage container of which is removable, serves as a dispensing and closing element a conical coil spring in connection with a valve disc. Will the coil spring stretched and at the same time the discharge opening closed by the valve disk, so trickles the powder through between the individual turns of the coil spring. Though as a result sooner or later the coil spring becomes encrusted and clogged, it is so inaccessible that that they and the valve disc are difficult to clean.

In a further known embodiment, there is a metered allocation of the powder with the aid of a Notched piston is provided, but a plate closing the reservoir is on the container and welded to the plate a grommet forming the lower outlet opening. This creates a one-piece construction, which even after loosening a split pin and removing the notched piston hinders easy cleaning, since the discharge opening of the container, the outlet opening and the storage space between the two openings is very difficult to access.

The invention is based on the object of solving these difficulties by means of an easily removable design to remedy. According to the invention, the plate is removably on an annular shoulder of the housing on and is held by the guide arranged above it for the piston valve, which is downwardly narrowing notches in cross section are arranged in a manner known per se so that they si.ch in a lower one, both the outlet opening in the plate and the discharge opening in the bottom of the Housing closing position of the piston located between the plate and the bottom of the housing and in an upper, the outlet opening in the bottom of the housing exposing position above the plate. Due to the arrangement, the individual parts of the dispenser can be easily removed at any time and clean.

The invention will now be explained with reference to the embodiment shown in the drawing. It shows

F i g. 1 is a perspective view of a dispenser according to the invention;

2 shows a partial section along the line 2-2 of F i g. 1, the dispensing mechanism of the dispenser is shown in longitudinal section, and

3 shows the individual parts of the distribution mechanism in an exploded arrangement.

As can be seen from the drawing, the dispenser has a housing 1 which contains a distribution mechanism, in particular a piston valve 3, a plate 8 which creates a central discharge opening 9, and a guide 10 which supports the piston valve 3. The interior of the housing 1 is provided with an annular shoulder 24 for supporting the exchangeable plate 8. The upper part of the housing 1 above the annular shoulder 24 can directly contain a container or, as in FIGS. 1 to 3 shown, receive a bearing bush 2 into which a container 17 is inserted. For the concept of the invention, it is unimportant whether a special bearing bush or a container is used, the discharge end of which can perform the function of a bearing bush. However, the present dispenser can be combined with a variety of containers using different bearing sleeves. The upper end 21 of the bearing bush 2 serves as a support for the neck part 18 of the container 17. This neck part has an outside diameter that is only just that much smaller than the inside diameter of the end 21 of the bearing bush 2
