Patent

CA 2251833

A closure (10) for a container comprises a spout portion (15) having a flange (25), a cap portion (35), and a link (135). The link (135) connects the spout portion (15) to the cap portion (35) at first (155) and second (50) joints. The link (135) is folded about the first joint (155) so that a portion (150) of the link (135) overlies the flange (25) and is bound thereto. The flange (25) may include a cutout (200) which receives the portion (150) of the link (135). The second joint (50) allows securement and removal of the cap (35) from the spout (15) while portion (150) of the link (135) overlies the flange (25). The portion (150) of the link (135) is bound to the flange (25) in an energy emission process which concurrently bounds the flange (25) to a thermoplastic surface of the container. A tamper evident structure (275) connects the cap (35) to the flange (25).

Fermeture (10) pour un récipient comprenant un élément goulot (15) muni d'une collerette (25) et d'un élément de liaison (135). Ce dernier relie l'élément goulot (15) à l'élément bouchon (35) par un premier (155) et un second (50) joint. L'élément de liaison (135) se replie autour du premier joint (155) de manière qu'une portion (150) de celui-ci recouvre la collerette (25) et se fixe sur cette dernière. La collerette (25) peut être munie d'une découpe (200) pour recevoir la portion (150) de l'élément de liaison (135). Le second joint (50) permet de mettre ou d'enlever le bouchon (35) sur le goulot (15) tandis qu'une portion (150) de l'élément de liaison (135) recouvre la collerette (25). La portion (150) de l'élément de liaison (135) est attaché à la collerette (25) par un procédé dégageant de l'énergie, fixant simultanément la collerette (25) à une surface thermoplastique du récipient. Une structure d'inviolabilité (275) relie le bouchon (35) à la collerette (25).
