Title (EN) CLOSURE
(FR) FERMETURE
Abstract:
(EN) A PT (Press-on/Twist-off) closure cap comprises a shell (2) including a skirt (4) and an end panel (3). A one-piece, preformed gasket (6) is secured in position within the shell, and performs a dual function, firstly to form a seal between the end panel (3) and an end sealing surface (12) on a container such as a glass jar, and secondly to provide a thread retention portion (8) between the skirt (4) and a thread finish (11) provided on the container. The thread retention portion (8) ensures that the closure may be initially applied by an axial movement and subsequently removed by a rotary movement. The preformed gasket is preferably formed of a polypropylene material or a Thermoplastic Elastomeric material having a flexural modulus of between 30 and 900 MPa.
(FR) L'invention se rapporte à une capsule à fermeture par pression et ouverture par dévissage. Cette capsule comporte une enveloppe (2) dotée d'une jupe (4) et d'une extrémité plane (3). Un joint d'étanchéité composé d'une seule pièce et préformé (6) est fixé à demeure à l'intérieur de l'enveloppe et remplit une double fonction, premièrement, celle d'un joint entre l'extrémité plane (3) et une surface d'obturation étanche terminale (12) située sur un contenant tel qu'un bocal en verre et, deuxièmement, celle d'une partie de maintien filetée (8) située entre la jupe (4) et la bague filetée (11) du contenant. Grâce à cette partie de maintien filetée (8), la fermeture peut d'abord être appliquée par mouvement axial puis annulée au moyen d'un mouvement rotatoire. Le joint d'étanchéité préformé est de préférence formé dans une matière polypropylène ou une matière élastomère thermoplastique présentant un module d'élasticité en flexion situé entre 30 et 900 MPa.
