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.

Abstract: A zipper retainer can sense an illegal intrusion to a trunk (or bag). The retainers may be a hollow seat of any desired shape. One or two selected lateral walls or a selected surface of the seat is installed with at least one though hole. A front lateral wall and a rear lateral wall are formed with at least one tip post. Thus, when the zipper of the trunk or bag is closed, the retainer will be combined so that the zipper pieces pass through the though hole of the seat to be in a locking condition. The tip posts are inserted into the two lateral material strips of the zipper; and therefore, the structure is inseparable. When the retainer is destroyed by others, the user may know that the trunk (or bag) has been intruded.
