Freeze-dried coffee is stored apart from the atm. and is dispensed perfectly at the 'critical' rate to produce good coffee. The dispenser receptacle has a lid which can only be removed for refilling and which incorporates a cylindrical pivot with two symmetrical opposite cavities to cooperate with two rectangular windows in the body of the lid. One window communicates with the interior and the other with the outside. The body and pivot are of isotactic polypropylene. |
