It is then maintained in the constrained state in the ring before and after fixing this assembly on the neck of the container.
• this attachment of the seal 2 in the ring 1 results from the cooperation, preferably exclusive, of the outer lateral edge 23 of the seal 2 with the ring 1, and in particular with the side wall 12 of the ring.

• these profiles are in the form of internal bulges, present eight in number in this example, arranged equidistantly on the side wall 12 of the ring being respectively separated from each other by an angle of 45 °.
• Such a structure thus gives rise to profiles projecting substantially radially inwards from the internal face of the outer lateral wall 12 of the ring, which are able to bite into the outer lateral edge 23 of the seal in order to maintain it.
• fixative The diameter at the radial ends of said bulges is therefore less than or equal to the diameter of the outer lateral edge 23 of the seal 2 to ensure a tight attachment thereof.

• These profiles comprise several external protuberances, in this case three, distributed equiangularly around the external lateral edge 23 of the seal. These protuberances, spaced at an angle of 120 ° relative to each other, thus protrude radially outwardly from the outer lateral edge
• the side wall of the ring which in the above examples is defined as also forming the fastening means (crimping, screwing, snapping or other) of the ring on the neck, could also be an intermediate side wall, devoid of such fixing means, being for example between the mounting part and a specific fixing part dedicated to fixing the ring on the neck. This intermediate side wall could then be used to hold the neck gasket in the ring. It is also conceivable to provide fastening profiles both on the seal 2 and on the ring 1.
