  • the lower end section of the skirt is straight.
  • a stretch of the lower end section of the skirt extends under the lower end of the peripheral wall of the bottom and it is folded inwardly at 180° so that the lower edge of the sheet is arranged against the said lower end of the peripheral wall.
  • a stretch of the lower end section of the skirt extends under the lower end of the peripheral wall of the shoulder, said stretch being rolled inwardly and welded on itself to form a bead extending just under the lower edge of the peripheral wall.
  • the stretch is folded inwardly at an angle greater or equal to 90°.
  • the tube is neckless.
  • the peripheral wall of the bottom is tightly secured to the lower end section of the skirt by ultrasonic welding.
