COFFEE MILL

A unit includes a container module with a coffee bean container and a portioning device for metering coffee beans. The module as a whole is configured for connection to a coffee apparatus, the connection enabling a metered delivery of coffee beans from the module into a grinder. The coffee bean container is tightly closed prior to the first use and, after an opening operation, has an opening through which coffee beans enter into the portioning device. The coffee bean container is coupled with the portioning device in a releasable and reconnectable manner by use of a coupling element. The opening can be closed again when the coffee bean container is separated from the portioning device. The unit makes it possible to handle and enjoy coffee in a cost-effective and environmentally aware manner.
