The invention concerns a method for crowning a container neck (4), such as a bottle, by securing or crimping a cap (1, 1', 1") provided with a skirt (2) on said neck, said neck (4) comprising a glass ring (41) with a lower shoulder (42), which consists in: a) crimping said cap (1, 1', 1") to said neck (4), so as to form said swaged portion (20) of said skirt (2); b) marking said swaged portion (20) of said skirt (2) with an etching device (7, 8) forming an etching (5) on said swaged portion (20) based on an etching pattern (52). The visual mark reduces the mechanical properties of said swaged portion (20), so as to prevent any fraudulent attempt to uncrimp said cap from said neck or any recycling of the bottle.
Dans ce procédé de capsulage d'un goulot (4) d'un récipient, par exemple une bouteille, par solidarisation ou sertissage d'une capsule (1, 1', 1") dotée d'une jupe (2) sur ledit goulot, ledit goulot (4) comprenant une bague de verrerie (41) avec un épaulement inférieur (42) : a) on sertit ladite capsule (1, 1', 1") audit goulot (4), de manière à former ladite partie rétreinte (20) de ladite jupe (2), b) on marque ladite partie rétreinte (20) de ladite jupe (2) par une dispositif de gravure (7, 8) en formant une gravure (5) sur ladite partie rétreinte (20) selon un motif de gravure (52). Avantages : le marquage visuel diminue les propriétés mécaniques de ladite partie rétreinte (20), de manière à empêcher toute tentative frauduleuse de dé-sertissage de ladite capsule dudit goulot ou tout recyclage de bouteille.
