Melitta drip style 10 cup coffee filter holder 1980 Germany

Here is hardly used (if ever) drip style coffee filter holder to put directly on a coffee can. It is branded with the German coffee maker name Melitta, the red decal is also still on it. It is also marked 1×10 (cups) and “Made in Germany”. I am guesstimating it was made around the 1980’s. It is completely made of durable plastic. It makes 5-10 large cups or a full can of medium strong coffee. It is a system that requires a round paper filter to hold the coffee grind, which is still being sold today.
