Abstract
Abstract A generally plate-like bag closure device that includes an entry throat which guides the twisted neck of a bag into an interior mouth section, the bag''s twisted neck being retained within the mouth section by a plurality of contiguous teeth to hold the bag in a closed attitude. The mouth section of the plate-shaped bag closure is subdivided into a closure area and a latching area, each area being provided with a plurality of teeth that are contiguous one to the other. Further, the teeth within the mouth section are disposed in mirror relation relative to a center line that bisects the mouth section and the entry throat.
