Patent

CA 2381059

The closure device (121) includes interlocking fastening strips (130, 131) and a slider (132) slidably disposed on the fastening strips (130, 131) for facilitating the occlusion and deocclusion of the fastening strips. The external surface of the slider is designed to alter the way in which the slider will be grasped by the user. By providing outwardly protruding surfaces (160, 162) on the side portions (142, 144) of the slider, the slider will be grasped near the front or back of the slider. Thus, the user experiences a feeling that the slider is easier to move along the fastening strips. In another embodiment, by providing a gripping surface (550) near the top portion (540) of the slider (532), the slider (532) will be grasped near the top portion of the slider (532). Thus, the slider (532) will be easier to move and the slider (532) reduces the tearing that may result when too much pressure is applied to the bottom portion of the slider during movement of the slider.

Cette invention concerne dispositif de fermeture (121) comprenant des bandes de fixation autoverrouillables (130, 131) et un coulisseau (132) qui est monté coulissant sur les bandes de fixation et dont il facilite la fermeture et l'ouverture. La surface extérieure du coulisseau est conçue de manière à modifier la manière dont ledit coulisseau est saisi par l'utilisateur. Grâce à des surfaces en saillie (160, 162) sur ses flancs (142, 144), le coulisseau peut être saisi à proximité de sa partie avant ou arrière. L'utilisateur a ainsi l'impression que le coulisseau glisse plus facilement sur les bandes de fixation. Selon un autre mode de réalisation, la présence d'une surface de prise (550) près de la partie supérieure du coulisseau (532) facilite le déplacement de ce dernier et réduit les risques de déchirure qui peuvent se produire lorsqu'une pression excessive est appliquée sur la partie inférieure du coulisseau pendant son déplacement.
