Title (EN) CLOSURE SYSTEM COMPRISING A THERMOCHROMIC TAMPER CONTROL MEANS
(FR) SYSTEME DE BOUCHAGE AVEC CONTROLE D’EFFRACTION THERMOCHROME
Abstract: front page image
(EN)The invention relates to a closure system comprising a thermochromic tamper control means, whereby the colour of said means is irreversibly altered should the temperature of the closure system increase beyond a threshold temperature. The inventive closure system comprises a polymer matrix incorporating at least one thermochromic pigment having a colour which is irreversibly altered following the exposure of the closure system to a temperature in the region of, or above a threshold temperature. The invention also relates to the method of preparing the thermochromic closure system and to containers which are equipped with said closure system.
(FR)La présente invention concerne un système de bouchage comprenant un moyen de contrôle d’effraction thermochrome dont la couleur est modifiée irréversiblement en cas d’élévation de la température du système de bouchage au-delà d’une température seuil, ledit système de bouchage comprenant une matrice plymère dans laquelle est incorporé au moins un pigment thermochrome dont la couleur est irréversiblement modifiée après exposition dudit système de bouchage aux environs ou au-delà d’une température seuil. L’invention concerne également le procédé de préparation du système de bouchage thermochrome, ainsi que les récipients munis dudit système de bouchage.
