Abstract (en)
The filter-bag for infusion products comprises a tubular element made of a filtering material that cannot be subjected to thermal bonding and in which at least one median transverse folding line is formed and is adapted to define a first lobe (3) and a second lobe (4) that are meant to contain respective doses of an infusion product. The lobes (3,4) are folded together in packaging position and are rigidly closed by folding at an angle the corners (5) that correspond to the opposite ends of the tubular element, so as to form a trapezoidal profile, and by subsequently folding an end flap (6) of the first lobe (3) over the corresponding edge of the second lobe (4). A handling string (7) made of natural fiber is rigidly coupled, at one end (7a), to the folded flap (6) of the lobes by means of a seam (8) for closing the lobes with natural fiber thread, and a label (9) is fixed at the free end of the handling string. <IMAGE>
