ABSTRACT:
A single-lobe filter bag for infusion products comprises: a length (2) of filter material forming a chamber (3) containing a charge of the infusion product; the length (2) comprises a first closed top end (5) formed by a first join (S1) between two first end edges of the length (2); a second bottom end (7) closed by a second join (S2) designed to form a bottom surface (11) of the filter bag (1) and formed by two second end edges (7a,7b) placed over each other to form a central extension of the second end (7); the second end edges (7a,7b) are positioned face to face with each other and joined in such a way as to form a tab (12) that protrudes from the bottom surface (11); two sides (8, 9) which connect the first end edge (5) and the second end edge (7) and which are at least partly folded onto each other to form a fold towards the inside of the chamber (3); a string (13) joined, at one end, by a knot (A1) to the length (2) and, at the other end, by a knot (A2) to a tag (14), the string (13) being looped around the length (2).
