- Figure 3 illustrates the fact that the cellulose-based structural part 2 can have a complex three-dimensional geometry.
- This part 2 1 of the cellulose-based tube head 1 can be obtained from single-layer or multi-layer sheets based on cellulose, such as sheets of formable paper or cardboard.

- the barrier layers to humidity and to gases or aromas present in the skirt 11 and in the tube head 1 are not shown because these layers are very thin. It is advantageous for many packages to have the barrier layer or layers positioned in the thickness of the skirt close to the internal face and to have the barrier layer or layers in the thickness of the tube head positioned close to the outer face. Thus during the assembly operation (when the tube head is placed inside the skirt for their attachment to each other), the barrier layers of the tube head 1 and of the skirt 11 are located close to each other, guaranteeing continuity of the barrier at the level of the weld and consequently a very tight packaging.
