CA 2239654

A tamper-indicating closure is used with an associated container having a finish including an external thread formation thereon, and an annular locking ring located axially under the thread formation. The closure includes a closure cap having a circular top wall portion and an annular skirt portion depending from the top wall portion. An internal thread is formed in the skirt and defines a skirt wall plane. The closure includes an annular tamper-indicating band depending from the cap that is detachably connected to the cap by a plurality of circumferentially spaced, tapered, frangible connectors extending between the band and the cap. The connectors taper to define a region adjacent to a juncture of the connector and the band having a cross-section that is smaller than a cross-section at a region of the connector adjacent to a juncture of the connector and the closure cap.

Fermeture avec indication de manipulation frauduleuse. La fermeture est utilisée avec un contenant à bord supérieur correspondant qui inclut un filetage externe formé sur ce dernier, et un anneau de verrouillage annulaire situé axialement sous le filetage. La fermeture comprend un couvercle ayant une partie supérieure circulaire et une jupe annulaire dépendant de la partie supérieure. Un filetage interne, formé dans la jupe, définit un plan de la paroi de la jupe. La fermeture comprend une bande annulaire, avec indication de manipulation frauduleuse, dépendant du couvercle. Elle est raccordée à ce dernier de manière non permanente par plusieurs connecteurs destructibles, effilés et espacés sur la circonférence se prolongeant entre la bande et le couvercle. Les connecteurs s'amenuisent de façon à définir une région contiguë à un point de rencontre du connecteur et de la bande ayant une coupe plus petite que celle de la région du connecteur contiguë au point de rencontre du connecteur et du couvercle.
