Abstract
An improved apparatus for the production of aromatic extracts from coffee or tea is of the type having a filter vessel and a collecting container, wherein the filter vessel has a plurality of detent lugs which are received within detent recesses disposed in an upper rim portion of the collecting container for detachable engagement therewith. This construction results in the secure connection of the filter vessel atop the collecting container, for preventing accidental detachment of the filter vessel while permitting intentional detachment of the filter vessel by proper manipulation of a handle portion of the filter vessel to disengage the detent lugs.
