Abstract
Abstract A tamperproof, reclosable carton construction wherein, after removal of a zipper strip to open the carton, reclosure is effected by tucking a front cover flap between the outside surface of the receptacle front wall and the inner surface of front corner flaps which overlie, but are not adhered to, the end portions of the receptacle front wall. Integrity of the front corner construction is maintained by extension tabs hinged to the front corner flaps and adhered to the bottom panel of the carton.
