Tubular glass bottle neck

A tubular glass bottle neck including:

• a tubular wall, connected in continuation to a bottle body, defining an inner conduit, an outer wall face, and a mouth accessible from outside the bottle;
• a protruding annular collar on the outer surface of the tubular wall in a position adjacent to the mouth, with said annular collar being provided with an outer collar face confined between two annular collar projections;
• wherein
• said tubular wall defines a collar segment (A), a transition segment (B), and a wide segment (C) successive to and aligned with one another and with their respective inner conduits being connected to one another,
• the collar segment (A) includes the annular collar and the mouth, with the thickness of the annular collar being added to the thickness of the tubular wall in at least part of said collar segment (A);
• the outer wall face of the wide segment (C) is flush with the outer collar face, and the inner conduit thereof has a cross section having a larger size than the cross section of the inner conduit of the collar segment (A);
• and
• the transition segment (B) links the collar segment (A) and the wide segment (C), the inner conduit thereof comprises successive cross sections having an increasing size connecting the inner conduits of the collar segment (A) and the wide segment (C), and the outer wall face thereof has at least two successive cross sections having a different size, connecting the outer wall faces of the collar segment (A) and the wide segment (C), defining an annular outer recess between the collar and the wide segment (C).
