Description

technical field [0001] The present invention relates to a method of packaging dried edible leaves or stems, including tea leaves, herbs or spices, into a sealed box. Background technique [0002] Methods are known for producing sealed cartridges containing contents such as coffee, broth or tea for brewing hot drinks. Methods for packaging the contents in cartridges are described, for example, in WO2008 / 129530 and WO2010 / 007633. Typically, the sealed cassette is placed in a machine comprising an injection head and a perforated bottom wall. The injection head penetrates one wall of the cartridge to inject hot water into the cartridge, and the perforated wall opens the opposite wall of the cartridge to extract the beverage as the water passes over the contents contained in the cartridge. By packaging a substance such as coffee or tea in a sealed case, the properties of the substance can be preserved for a relatively long time until the beverage is prepared. [0003] As far a...
