Abstract
A device (10) for the dosed discharge of a powder-form medium, in particular ceramic powder for dental purposes, including a storage container (12) with a first outlet (40), as well as a slider (20) with a receptacle (18) for a quantity of medium to be dosed, which can be selectively aligned with a first outlet or a second outlet (50), through which the medium can be discharged. In order to achieve reproducible discharge of a defined quantity of free-flowing medium in an uncomplicated design, and since there is no requirement for re-usability after emptying the storage container, the invention proposes that the slider (20) be connected to at least one spring element (26, 28), which admits a force upon the slider to align the receptacle (80) with the first receptacle (40), and that the receptacle can be secured by a lock element (34) in a position aligned with the second outlet (50).
