<p>The invention relates to a cylindrically shaped packaging container and a method of manufacturing the latter, said container comprising a supporting outer sleeve (10), formed by spiral winding of at least one overlapping strip (11, 12, 13, 14), and comprising an inner sleeve (20) which is likewise wound spirally from an overlapping strip (21) of a suitable lining material, the strip (21) forming the inner sleeve (20) being provided with a coating (22) on its inside facing the winding axis, and the mutually overlapping parts of said spirally wound strip (21) being joined together. In order to provide a method which is simple to carry out and a packaging container which can easily be separated into its two main constituents, the rear edge (23) of the strip (21) which forms the inner sleeve (20) and is provided with the coating (22) on the inside is folded forwards through 180 DEG prior to the winding process and joined by means of the coating (22), which thus faces outwards, to the front edge of the following winding of the strip (21) via its coating (22). At least one strip (11, 12, 13, 14) is wound spirally onto the inner sleeve (20), thus produced, to form the outer sleeve (10) by adhesion alone, said strip (11, 12, 13, 14) being connected only to itself in its overlapping region or, if a plurality of strips are used to form the outer sleeve (10), to said strips (11, 12, 13, 14) by a bonding material, preferably glue, applied prior to the winding process. <IMAGE></p> |
