The invention concerns a tube (1) provided with a head (10) and a skirt (2) having an orthogonal cross section of particular shape whereof the largest inscribed circle has a diameter D. The head designed for fixing of a rigid closure is provided with a circular cylindrical wall (11) extending towards the inside of the tube and enclosing an orifice concentric to said inscribed circle and having a large diameter, typically more than 0.8*D and takes up substantially the internal volume of the skirt (2) end over a height less than D, preferably less than D/3. The invention also concerns a closure element (20), in particular a convenience closure (200), adapted to be fixed substantially irreversibly on the inventive tube head comprising a base (21) whereof the external outline matches the shape of the orthogonal cross section of said tube skirt (2) and provided with a skirt whereof the diameter ranges between 0.5*D and 0.9*D and equipped with means for irreversibly fixing (25) the closure element (20, 200) on the head (10) on the tube (1).
Tube (1) fitted with a head (10) intended to fix capping (20) according to any of claims 10 to 17, and with a cylindrical or prismatic skirt (2) having an orthogonal section of any shape whose largest inscribed circle has a diameter D, characterized in that the head is provided with a circular cylindrical wall (11) extending towards the inside of the tube, surrounding an opening (15) concentric to said inscribed circle and having a diameter typically lying between 0.5*D and 0.9*D, and in that it essentially occupies the inner volume of the end of skirt (2) over a distance of less than D, preferably less than D/3.
Tube (1) according to claim 1 fitted with a head (10) intended to fix capping (20) according to claim 12, in which the head is also provided with a peripheral wall (12) which extends the skirt (2) of the flexible tube over a short distance, typically in the order of one millimeter, and is slightly recessed inwards over a distance corresponding to the thickness of the peripheral skirt (24) of the capping (20).
Tube (1) according to claim 2 fitted with a head (10) intended to fix a service-cap (20) according to claim 13, in which said peripheral wall (12) is provided with cavities (121) intended to receive housings (204) of extension parts (203) of the hinge (202 and 203).
