       24 . A container for use in a set of containers, comprising
 an opening that comprises a plurality of toothlike protrusions on an inner circumference of said opening of the container,   said toothlike protrusions being spaced apart from each other in a circumferential direction, and extending transversely to an axis of the opening of the container,   wherein said toothlike protrusions are adapted to engage with an external thread positioned on a container neck of a second container by plugging-on or screwing-in.   
   
   
       25 . The container according to  claim 24 , wherein the toothlike protrusions have a radially inwardly decreasing thickness. 
   
   
       26 . The container according to  claim 24 , further comprising venting cross sections positioned between the toothlike protrusions. 
   
   
       27 . The container according to  claim 24 , wherein the opening of the container comprises merlons positioned on an upper brim of the opening, in axial extension of the toothlike protrusions. 
   
   
       28 . The container according to  claim 24 , wherein the merlons extend radially outwardly from the inner circumference of the opening. 
   
   
       29 . The container according to  claim 24 , wherein the opening is formed in a container neck comprising an external thread. 
   
   
       30 . The container according to  claim 24 , wherein the container is a collapsible tube. 
   
   
       31 . The set of containers according to  claim 17 , further comprising venting cross sections positioned between the toothlike protrusions. 
   
   
       32 . The set of containers according to  claim 17 , wherein the opening of the second container comprises merlons positioned on an upper brim of said opening of the second container, in axial extension of the toothlike protrusions.
