Metal container comprising a neck capable of receiving a screw cap-type sealing element

A metal container comprising a neck defining a longitudinal axis, wherein said neck includes a wall of constant, or at least approximately constant, thickness which is ended by a free edge delimiting an orifice and in which are arranged at least two beads:

• a first bead forming at least one thread, and
• a second, convex bead forming a ring collar arranged between said thread and a neck base,
• wherein said ring collar includes a lateral face extended by two flanks, a lower flank and an upper flank, and said lower flank is delimited by a rounded external edge and by a rounded internal edge, connected to said lateral face and to said neck base, respectively,
• wherein:
• a) said thread includes:
• a1) a cross-section radius at a crest comprised between 0.85 and 1.2 mm, and
• a2) a cross-section radius at a root comprised between 0.5 and 0.7 mm,
• b) the lower flank of the ring collar, diverging with respect to the upper flank towards the longitudinal axis, defines an angle comprised between 20° and 30° with respect to a plane perpendicular to the longitudinal axis,
• c) the external edge of the lower flank of the ring collar has a cross-section radius comprised between 0.7 and 0.9 mm, and
• d) the internal edge of the lower flank of the ring collar is arranged at a distance comprised between 13 and 15 mm with respect to said free edge of the ring.
