A closure device (121) with interlocking fastening strips (130, 131) and a slider (132) that establishes a leak proof plastic bag (120). The ends of the fastening strips are heat sealed, melted or otherwise secured together. The fastening strips (130, 131) include a second seal (129) disposed in close proximity to one of the ends of the fastening strips. The second seal (129) is formed by heat sealing to melt the fastening strips together. The second seal (129) prevents the separator (172) of the slider from deoccluding or forming a gap when the slider (132) is at the occluded end. The second seal (129) extends midway up the fastening strips (130, 131) so that the separator (172) moves over the second seal (129) during movement of the slider towards the end. An unmelted portion (119) of the fastening strips (130, 131) is disposed between the second seal (129) and the end of the fastening strips to maintain the guide rails (139, 143) and to prevent the slider (132) from disengaging the fastening strips (130, 131).

L'invention porte sur un dispositif (121) de fermeture comportant des bandes de fixation (130, 131) à emboîtement et un curseur (132) permettant de constituer un sac étanche de plastique (120). Les bandes de fixation (130, 131), dont les extrémités sont reliées par thermoscellement, fusion ou d'autre manière, comportent une deuxième soudure (129) par thermoscellement solidarisant les deux bandes et en empêchant le déboîtement par le séparateur (172) du curseur, ou la formation d'un vide lorsque le curseur (132) se trouve à l'extrémité fermée. La deuxième soudure (129) s'étend jusqu'au milieu des bandes (130, 131) si bien que le séparateur (172) passe sur la deuxième soudure (129) lorsque le curseur se dirige vers l'extrémité. Une portion (119) non soudée des bandes (130, 131) se trouve entre la deuxième soudure (129) et l'extrémité des bandes de manière à maintenir les rails guides (139, 143) et empêcher le curseur (132) de se dégager des bandes (130, 131).
