• the outer surface 16 of the tube 10, preferably of the skirt 30 may be decorated in the following decoration process.
• the mandrel 76 is placed in the internal volume 12 of the tube 10.
• the suction means 80 located at the first end 82 of the mandrel 76 applies a depression in the internal volume 12 of the tube 10 in order to bring the tube 10 into contact with the mandrel 76 and to maintain a surface contact between the tube 10 and the mandrel 76.
• the decoration tool rotates relative to the tube 10 and applies a force on the tube 10.
• the force applied by the decoration tool on the tube 10 slides the tube 10 in rotation relative to the mandrel 76, provided that their respective reliefs are not already in the locking position, under the effect of suction.
• the decoration is made, for example, by silk screen printing or hot stamping.
• the decoration is developed on the outer surface 16 of the tube 10, preferably on the surface of the skirt 30.
• the tool around the tube 10, the tool or the tube 10 can remain fixed.
• the decoration tool spreads and prints the decoration on the outer surface 16 of the tube 10.
• the decoration can be made alternatively by screen printing.
• the decoration is applied by a cylinder in external contact with the tube 10 which deposits the ink on the outer surface 16 of the tube 10.
• a tube decoration 10 may require the successive application of several of these methods.
• the reliefs of the tube 42 and the mandrel 86 then cooperate to block the sliding in rotation.
• the surfaces 44 of the tube 10 made it possible to center and block the tube 10 with respect to the mandrel 76.
• the time required for the tube 10 and the mandrel 76 to block the sliding phenomenon by rotation is reduced.
• the movement of the tube 10 with respect to the mandrel 76 is essentially rectilinear throughout the decoration process.
• the residual slip between the mandrel 76 and the tube 10, resulting in particular from the centering of one on the other, is less than 5 ° angle.
• the tube 10 is decorated and corked directly after its manufacture.
• the effort to be transmitted by each relief 42 of the tube 10 is relatively small compared to the effort of decoration or the corking effort.
• the tube 10 according to the invention may comprise either a plug or a decor, preferably both.
• the mandrel 76 used during capping and the mandrel 76 used during the decoration may be identical.
• they can constitute a single piece used successively for the decoration process and the corking process.
• the rotational slip that occurs in the corking step is virtually nil. Keeping the tube 10 in position relative to the mandrel 76 made on the inner face of the tube 10 during capping limits the risk of damage done to the decor.
