Abstract
A filter bag for containing a substance for infusion in a liquid comprises: a containment chamber with compartments for doses of the substance, sealed by top and bottom joins; a tag for picking up the bag; and a section of thread, wound around the outside of the containment chamber and extending along an outline of the chamber, one end of the thread being connected to the pick-up tag and the other to the top of the containment chamber. The section of thread is longer than the outline of the containment chamber to which it is attached. The excess length of the section of thread relative to the outline of the chamber is gathered on the outside of the containment chamber for the substance for infusion and is attached to the pick-up tag. A method for production of the filter bag is also part of the invention.
