A container comprising a neck and a mouth, the neck extending mainly along a longitudinal axis and comprising:
- an upper portion comprising a screw thread provided around the longitudinal axis,
- a lower portion,
- an engagement surface transverse to a plane perpendicular to the longitudinal axis,
- in which the engagement surface comprises a first part which extends on said lower portion,
- wherein
- said screw thread has a crest diameter and said first part of said engagement surface defines a minimum diameter, said crest diameter is greater than said minimum diameter of said first part of said engagement surface,
- the engagement surface comprises a second part which extends on the upper portion, and
- the second part of the engagement surface overlaps the screw thread over at least a longitudinal portion of the neck so that a radially protruding portion of said screw thread has a radially recessed portion defining said second part of said engagement surface, wherein said second part of said engagement surface is engageable with an engagement surface of a closure.
