For all such devices, steps A) and B) are identically performed. In step C) dispensing caps of different designs can be attached to the same shoulder. The different dispensing caps have only to be compatible with the dimensions of the shoulder. Welding the dispensing cap on the shoulder creates a water and airtight bond between these two parts .
