CA 2459683

A closure device (121) for a thermoplastic bag (120) which includes two opposing, longitudinally extending interlockable male and female fastening strips (130, 131) having respective male and female closure elements or profiles (134, 136) that are deformed to interdigitate and produce an audible clicking sound and or tactile effect that is perceptible to the touch as the closure device (121) is opened and closed. Interdigitation of the two profiles (134, 136) is achieved by cold forming the profiles (134, 136) while interlocked. The shape of the cold form is a stepped deflection (126a, 126b) of both profiles (134, 136) so that their shapes are generally congruent. The stepped deflections (126a, 126b) provide a change in the occlusion and peel force of the interlocking closure device (121) thereby resulting in an audible clicking or popping sound as the closure device (121) is opened and closed and a tactile effect that is perceptible to the touch as the closure device (121) is closed.

L'invention concerne un dispositif de fermeture (121) destiné à un sac thermoplastique (120) comprenant deux bandes d'attache (130) (131) opposées, mâle et femelle, verrouillables qui s'étendent longitudinalement et sont dotées respectivement d'éléments ou profilés de fermeture (134) (136) mâle et femelle. Lesdits éléments se déforment afin de s'emboîter et produire un <= clic >= audible et/ou un effet tactile perceptible au toucher lorsque le dispositif de fermeture (121) est ouvert et fermé. L'emboîtement des deux profilés (134) (136) est obtenu par formage à froid desdits profilés (134) (136) assemblés par liaison de forme. Ce formage à froid donne lieu à la formation d'une partie courbée étagée (126a) (126b) dans les deux profilés (134) (136) de sorte que leurs formes coïncident. Lesdites parties courbées étagées (126a) (126b) produisent une variation de la force d'occlusion et de décollement du dispositif de fermeture par liaison de forme (121), entraînant l'émission d'un <= clic >= ou d'un craquement audible lorsque leditdispositif de fermeture (121) est ouvert ou fermé et la création d'un effet tactile qui est perceptible au toucher lorsque le dispositif de fermeture (121) est fermé.
