Abstract

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).
