Embodiment Construction

[0038] figure 1 A perspective view of the dosage-dispensing device 100 with the drive device 150 is shown, in which the dosage-dispensing unit can be set in place in the drive device and subsequently removed again. The drive device 150 comprises a holding device having an upper part 157 and a lower part 158 ​​which are linearly movable towards and away from each other. This enables the use of dosage-dispensing units 110 of different lengths. For simple exchange of the dosage-dispensing unit 110 and precise dispensing operation, the dosage-dispensing unit 110 and / or the holding device need to be equipped with suitable mechanical and possibly electromechanical connections 149 , 148 which form complementarily to each other. The horizontal catch 147 and the vertical catch 146 are arranged on the second mechanical connection element 149, so as to ensure that the dosage-dispensing unit 110 in the holding device cannot fall out.

Abstract

A dosage-dispensing unit serving to store and dispense pulverous or granular dosage material has a housing which includes at least one receptacle space for dosage material and an outlet orifice connected to the receptacle space. The dosage-dispensing unit further includes at least one electrostatic coagulant means which affects the build-up and / or the break-down of a closure plug consisting of dosage material and / or of an aperture shutter consisting of dosage material in the outlet orifice. The closing or narrowing of the outlet orifice thus occurs as a result of the electrostatic attraction and coagulation of dosage material leading to at least partial obstruction of the outlet orifice with the dosage material by the build-up of a closure plug or an aperture shutter.

Description

technical field [0001] The present invention relates to dosage-dispensing devices for powdered or granular ingredients. Background technique [0002] Dosing devices of this type are used in particular for measuring small quantities of substances, such as toxic substances, into small target containers with great precision. Such target containers are often placed on a balance in order to weigh the quantity of substance delivered by the dosing device, which can then be further manipulated for a given purpose. [0003] The substance to be dispensed can be stored, for example, in a source container equipped with a dosing head. The substance to be dispensed to the outside is preferably passed through a small opening in the dosage-dispensing device, so that the substance can be filled into the container with a smaller hole cross-section. [0004] Dosing devices for dry and / or powdered bulk materials such as dyes are prior art and have been used. For example in US Pat. No. 5,145,...
