ABSTRACT:
A closure device made of flexible metal having in the middle, a weakened section which permits folding it, to form two segments, for adapting it to the corner of any bag or similar container.
As the segments are folded, to be assembled to the corner of the bag, upon one of the segments, are clinched to a band on the other segment for sandwiching the corner of the bag.
Both segments have along one side, perforations, through which knives a Stapling or assembling Machine will pass to cut the bag between the segments.
To open the bag, a part of the segments, with the corner of the bag held between them, must be separated from the band, ears and bag, by repeated bending of the segments to break at joints for tearing the corner off. Only the band with the ears attached to the bag remain to permit opening or closing the mouth of the bag.
