Abstract: The invention relates to a cardboard filter for cigarettes, formed by folding, winding and gluing a cardboard strip. According to the invention, the cardboard strip is folded to form a central portion having a series of lobes angularly equally distributed around a central axis of the filter and a peripheral portion surrounding the central portion, the lobes and the peripheral portion delimiting gas passage channels around the central axis.

Abstract: The present invention relates in particular to a set (2) of filters (10) made of cardboard or cellulosic material. In particular, the set is characterised by the fact that it is in the shape of a generally cylindrical stick which is made up of a plurality of individual filters (10), each formed of a winding on itself of a side made of cardboard or cellulosic material, said filters (10) being arranged in extension of one another and being partially connected in pairs by connecting means (3), such that it is possible to separate at least one filter (10) from. tile stick by removing or severing tile connecting means (3).

Abstract: The present invention relates in particular to a foldable container (1) for loose tobacco, which is delimited by two longitudinal walls (10, 11) which have a common longitudinal edge (101), and by two opposite transverse walls (12, 13) shaped like bellows, characterized by the fact that said transverse walls (12, 13) shaped like bellows consist of five successive pleats (P1, P2, P3, P4, P5), and that the two adjoining transverse wall elements (122, 123) which constitute at least one (P4) of said pleats are configured to occupy either a first position in which they form a re-entrant corner, or a second position in which they form an outer corner and thus constitute a pouring spout.
