<p>A method for angularly positioning an axially asymmetrical sealing device (2) relative to a flexible tube (1) for dispensing a substance with a liquid to pasty consistency, wherein the neck (5) of said tube (1) supports said sealing device (2) and delivers the substance through a dispensing channel, and the tube carries indicia (9) relative to which said sealing device (2) is to be adjusted. Said tube (1) is filled through its open bottom with the sealing device (2) in place, then sealed by flattening and heat sealing the end opposite the neck (5). At least one reference marking (11) is formed on the tube (1) and the sealing device (2) is mounted and adjusted relative to said reference marking (11), this marking (11) being printed on the tube concurrently with the indicia (9). The reference marking (11) is used when squeezing and heat sealing the end (10) of the filled tube (1).</p> |
