A rigid package for tobacco articles comprising: a container, which has a parallelepiped shape and has a front wall, a rear wall, a lower wall and two side walls; a single inner wrap which encloses a group of tobacco articles, is housed on the inside of the container and has a size that is smaller than the size of the container; a lid which is hinged to the container so as to close an open upper end of the container; a collar, which is arranged on the inside of the container so as to partially project outwards from the open upper end and comprises a first side wall which rests against a side wall of the container, a front wall, which rests against the front wall of the container, and a second side wall, which is opposite to the first side wall and rests against the other side wall of the container; and a filling element, which is autonomous and separate from the collar, is arranged on the inside of the container, is coupled to the inner wrap, consists of a blank that is folded and glued onto itself; wherein the filling element comprises at least one tubular body, which can be deformed in a flat configuration, in which the tubular body has a flat shape, and in an expanded configuration, in which the tubular body has a parallelepiped shape; the filling element can freely be deformed in the flat configuration and in the expanded configuration only when it is located outside the container, it can be inserted in the container only in the expanded configuration, and once it is arranged inside the container it can no longer be deformed from the expanded configuration due to the geometric constraints imposed by the walls (9, 10, 11) of the container, the package for tobacco articles is characterized in that the filling element compensates for the smaller size of the inner wrap in comparison to the size of the container. a container, which has a parallelepiped shape and has a front wall, a rear wall, a lower wall and two side walls; a single inner wrap which encloses a group of tobacco articles, is housed on the inside of the container and has a size that is smaller than the size of the container; a lid which is hinged to the container so as to close an open upper end of the container; a collar, which is arranged on the inside of the container so as to partially project outwards from the open upper end and comprises a first side wall which rests against a side wall of the container, a front wall, which rests against the front wall of the container, and a second side wall, which is opposite to the first side wall and rests against the other side wall of the container; and a filling element, which is autonomous and separate from the collar, is arranged on the inside of the container, is coupled to the inner wrap, consists of a blank that is folded and glued onto itself; wherein the filling element comprises at least one tubular body, which can be deformed in a flat configuration, in which the tubular body has a flat shape, and in an expanded configuration, in which the tubular body has a parallelepiped shape; the filling element can freely be deformed in the flat configuration and in the expanded configuration only when it is located outside the container, it can be inserted in the container only in the expanded configuration, and once it is arranged inside the container it can no longer be deformed from the expanded configuration due to the geometric constraints imposed by the walls (9, 10, 11) of the container, the package for tobacco articles is characterized in that the filling element compensates for the smaller size of the inner wrap in comparison to the size of the container.
