The invention relates to a device for dosed dispensing of a powder-form or granular material, provided with a container for the material having a dispensing opening through which a user can suck up the dosed material, operable dosing means arranged in the vicinity of the dispensing opening and operating means co-acting with the dosing means and movable manually by the user, wherein the dosing means are adapted to dispense a single dose of material at an operating movement of the operating means. The dosing means, which can be rotatable, are herein adapted for continuous transport of material from the container directly to the dispensing opening and are displaceable through a limited stroke by the operating means. The movement of the operating means is thereby bounded. The operating means can be linearly movable, wherein a transmission is then arranged between the operating means and dosing means. This transmission comprises for instance a gear rack connected to the operating means and, co-acting therewith, a toothed wheel connected to the dosing means, wherein one outer end of the gear rack co-acts with loop-shaped guide means. |
