Abstract
An infusion bag for making beverages from extractable substances includes first and second subchambers that are connected to each other at their upper and lower transverse edges. A rigid actuating handle having a rigid transverse web, is connected to the subchambers and permits the subchambers to be subjected to up and down movements so that infusion of the extractable substances can occur in a very short time.
