Abstract
A reclosable flexible container is provided as a pouch having a front wall with an inside and an outside surface, a rear wall with an inside and an outside surface and a pouch opening. A pair of exterior closure elements are provided for mechanical interlocking with a pair of interior closure elements. A wall of the pouch is interposed between each interior and exterior closure element. The interior closure elements further have a mechanical mechanism for selective interlocking with each other so as to seal the pouch or reopen it as desired. As a result a reclosable pouch is provided without the use of heat seals or adhesives.
