         4 . A packaging unit according to  claim 1 , wherein one end of the outer packaging provides a standing face for the packaging pouch projecting from the other end with a separable opening part. 
     
     
         5 . A packaging unit according to  claim 1 , wherein the packaging pouch which is arranged in the outer packaging in a pouch longitudinal direction corresponding to the tube axis is at least partially fastened on the inside of the outer packaging. 
     
     
         6 . A packaging unit according to  claim 1 , wherein the part lengths of the outer packaging separated along the straight fold edges are at least 20% of the length of the fold edges. 
     
     
         7 . A packaging unit according to  claim 1 , wherein the part lengths of the outer packaging separated along the straight fold edges are spaced apart by at least 10% of the length of the fold edges from the centre thereof and the ends. 
     
     
         8 . A packaging unit according to  claim 1 , wherein the outer packaging has openings consisting of two halves which are rotationally symmetrical with respect to the straight fold edges, the part lengths corresponding to connecting lines of the rotationally symmetrical halves of the openings.
