Abstract

An article is disclosed comprising a cylindrical hollow rod, composed of a shirred packaging tube, with an internal bore having a circular cross-section and ending in cavity openings at the two end faces of the hollow rod, in combination with a sheathing which surrounds the hollow rod, leaving the cavity openings free, and an annular body at one of the two cavity openings. The annular body comprises an annular disk, whose inner side face bears directly against the adjoining end face of the hollow rod. The outer side face of the disk is at least partially surrounded by the sheathing. The internal bore of the disk remains free of the sheathing and contains elements for fixing the disk to a cylindrical filler horn.
