Title (EN) IMPROVED CLOSURE FOR RECLOSABLE THERMOPLASTIC CONTAINERS
(FR) FERMETURE AMELIOREE POUR RECIPIENTS THERMOPLASTIQUES REFERMABLES
Abstract:
(EN) A closure (34) for reclosable plastic containers including male (36) and female (38) closure elements having extremities (46, 48) which are suited for interlocking with one another, in which the interlocking extremities (46, 48) of the male (36) and female (38) elements are guided into interlocking engagement responsive to compressive force placed on the elements (36, 38), as in the clamping together and edge-sealing of film portions (22) carrying the elements (36, 38).
(FR) Fermeture (34) de récipients en plastique refermables comprenant des éléments de fermeture mâle (36) et femelle (38) pourvus d'extrémités (46, 48) adaptées pour se verrouiller réciproquement, et dans laquelle les extrémités (46, 48) des éléments mâle (36) et femelle (38) sont amenées à se verrouiller réciproquement en réponse à une force de compression appliquée sur les éléments (36, 38), par exemple en serrant l'une contre l'autre et en refermant hermétiquement les rebords de parties en film (22) portant ces éléments (36, 38).
