The upper cover has an upper toothed tearing blade inside its free front end and the lower cover has a lower toothed tearing blade inside its free front end, abutting against an outer surface of the upper toothed tearing blade when the upper and the lower covers are closed. A press rib is provided inside the upper toothed tearing blade and a receiving rib corresponding to the press rib is provided inside the lower toothed tearing blade such that a length of outward pulled food wrap film can be clamped and pressed between the contacted press rib and receiving rib for stable tearing.
