Claim:
A packaging unit with a packaging pouch ( 10 ) of a flexible film-shaped first material and an essentially shape-stable outer packaging ( 28 ) of a second material, wherein the outer packaging ( 28 ) is tube-shaped with open ends ( 31 , 33 ) are situated in a plane perpendicular to a tube axis (z) and, in a first position, the ends ( 31 , 33 ) form a hexagon with two parallel sides (a, b) and two pairs of sides (c 1 , c 2 ; dl, d 2 ) each enclosing an angle α<180° lying symmetrically mirror-imaged to a plane of symmetry (E), and in a second position form a rectangle with two parallel sides (a, b) and two sides (c, d) lying perpendicular to the plane of symmetry (E), whereby in the first position a straight folding edge (g, h) runs between the corners of the two parallel sides (a, b) of both ends ( 31 , 33 ) lying mirror imaged symmetrical to the plane of symmetry (E), and in the second position the two parallel sides (a, b) of both ends lying mirror image symmetrical to the plane of symmetry (E) form an angle α=180°, and in the first and second position curved folding edges (l, k; l, m) run between the corners of the parallel sides (a, b) of both ends ( 31 , 33 ) lying parallel to the plane of symmetry (E) in such a manner that, in the second position, the outer faces ( 37 , 39 ) of the outer packaging ( 28 ) extending between the two parallel sides (a, b) of both ends ( 31 , 33 ) lying parallel to the plane of symmetry (E) are curved in a convex manner and the outer faces ( 41 , 43 ) of the outer packaging ( 28 ) extending between the two sides (c, d) of both ends ( 31 , 33 ) lying perpendicular to the plane of symmetry (E) are curved in a concave manner, whereby, by pressing together the straight folding edges (g, h), the outer packaging ( 28 ) can be moved from the first position into the second position, the one end ( 31 ) of the outer packaging ( 28 ) provides the packaging pouch ( 10 ) with a means for standing up the packaging pouch ( 10 ) projecting out of the other end ( 33 ) with a removable opening part ( 26 ), and the packaging pouch ( 10 ) situated in the outer packaging in a longitudinal direction (I) of the packaging pouch corresponding to the tube axis (z), is attached at least partially to the inner side of the outer packaging ( 28 ).
