Date Apr. 15, 1993.Method for angularly positioning an axially asymmetrical sealing device relative to a flexible tube for dispensing a substance with a liquid-to-pasty consistency. A neck of the tube supports the sealing device and dispenses the substance through a dispensing channel. The tube is provided with indicia relative to which the sealing device is located on the tube. The tube is adapted to be filled via its open bottom with the sealing device in place and then sealed by flattening and heat sealing its end opposite the neck. The tube also includes at least one reference marking and the sealing device is located on the tube relative to the reference marking, this reference marking being printed on the tube concurrently with the indicia. The reference marking is also used when squeezing and heat sealing the open end of the filled tube.
