Abstract
The closure device includes interlocking fastening strips and a slider. The ends of the fastening strips are heat sealed, melted or otherwise secured together. The fastening strips include a slit near the end of the fastening strips. The slit prevents the separator of the slider from deoccluding the fastening strips when the slider is at the occluded end. The slit allows the top edge of the fastening strips to bend around the separator while the fastening strips remain occluded.
