ABSTRACT:
PRIOR ART
The invention is based on an apparatus for volumetric metering of small quantities of product and dispensing them into containers. In a known apparatus of this type, the product to be dispensed, such as medicine powder, granulate or similar bulk product, is packed into the narrow metering chambers, which are open on the bottom, with punches, so that the product is held together in the form of a compact formation so the product can be transported to the evacuation station. However, a part of the product crumbles off on the underside, reducing the dose and soiling the apparatus as operation continues.
ADVANTAGES OF THE INVENTION
The apparatus according to the invention has the advantage that each of the metered quantities of a product have the same volume. Since a compact is not formed, less heat in a quantity of the product is generated, which is especially essential in heat-sensitive medications. Sticky products can also be processed with the apparatus of the invention.
By means of the provisions recited herein, advantageous refinements of and improvements to the metering apparatus defined are possible.
