ABSTRACT:
The present invention relates to a coffee powder metering device for coffee vending machines which, besides ensuring that all the coffee powder is metered out with no residue left behind, is also easy to manufacture.
The metering device comprises in a structure: a tubular main part, an end wall for closing off one end of the the tubular main part and a thrust wall in the tubular main part opposite the end wall. The tubular main part, end wall and thrust wall thus form a compartment for receiving a given quantity of coffee powder, through an inlet in one of the sides, and forcing it out through the end by utilizing the thrust wall. On the wall facing the compartment, the thrust wall is fitted with at least one movable lip held firmly by way of an elastic device against the tubular main part so as to scrape it clean.
