Abstract

Abstract Double cooperating overlapping closure flaps are provided to form one sidewall of a carton and detachably secured to an edge of one of the flaps is one or more coupons, which are longer in extent than the corresponding dimension of the sidewall of the carton; and to obviate obstruction in the insertion of the coupon upon closing the side flaps after the filling of the carton, provision is made for the supplying of the contents through one end of the carton rather than through the side closure. The end closure, for this purpose, comprises overlapping flaps extending from end edges of the front and back panels of the carton and tabs hinged to one of said sidewall flaps and to the opposite sidewall panel of the carton respectively.
