<p>A container (1) with a neck (2) provided with a dispensing closure which comprises a cap (4) provided with at least one dispensing port (7) that may be screwed in or out between at least two positions by means of at least one screw thread on the neck, as well as a reducer (3) which is integral with or attached to the neck and provided with a sealing tip (6) for selectively sealing the port (7) in the cap (4) depending on its position on the neck. The container neck (2) comprises two parallel limited screw threads (11a, 11b) engageable by respective pins (12a, 12b) in the cap, and the neck further comprises helical cap-mounting ridges (16a, 16b) whose winding directions change at 90° intervals so that the ridges together define two projections (17a, 17b) and two respective diametrically opposed recesses. A longitudinal groove (18) extends from each recess towards at least one of the screw threads (11a, 11b) for receiving one of the cap pins (12a, 12b) as the cap is mounted on the neck.</p> |
