Abstract
A process produces a tubular body with at least one dividing wall extending across its length and forming longitudinal chambers disposed next to each other. A foil strip is used whereby a dividing-wall strip or a section of dividing-wall strip is cut to length and is fastened at its lateral outer edges on the foil strip or section of the foil strip, with parallel alignment with the foil strip or section of foil strip. The lateral edges of the foil strip or section of foil strip are then joined with each other thereby either directly forming a tubular body or forming an endless tube, from which tubular bodies are then cut to length. The tube is then solidly joined with a tube head having a dividing bridge conforming to the arrangement of the dividing wall in the tubular body. The tube head has a dispensing aperture closable by a closure.
