ABSTRACT:
Disclosed is a supporting sheath for a longitudinally shirred packaging tube, comprising a generally tubular shaped supporting sheath comprised of a thermoplastic synthetic resinous material and having an inside diameter slightly larger than the outside diameter of the shirred packaging tube and a length substantially greater than the length of the shirred packaging tube, so that when a shirred packaging tube is placed inside of the supporting sheath, two projecting ends of the supporting sheath remain; a pair of generally planar disk elements, each including a central aperture therein, each of the disk elements having an outer diameter which is approximately equal to the diameter of the supporting sheath; each of the disk elements being adapted to be slid with its aperture over one of the projecting ends of the supporting sheath and abutted against the end of the shirred packaging tube contained in the supporting sheath and being adapted to contact the supporting sheath at least along its planar surface facing away from the packaging tube and along its outer circumferential edge when the sheath is turned back 180.degree. upon itself; and wherein each of the turned-back projecting ends of the supporting sheath has a permanently form-stable configuration produced by heat forming. Also disclosed is a functional unit comprising the supporting sheath and a shirred packaging tube, as well as a method for producing the functional unit.
