Abstract
A divider panel assembly for a carton which has a handle panel and an anchor panel which are interconnected by tear bars is cut to form the tear bars in a manner which will maintain the strength of the handle panel while facilitating the separation of the handle panel and the anchor panel. The joint between the handle panel and the anchor panel is formed by providing a plurality of cuts at the connection between the handle panel and the anchor panel. Each joint has first, second and third cuts which are arranged to form tear bars therebetween which are of a greater length than the tear bars previously known so as to facilitate the initial movement of the handle with respect to the anchor panel and the ease with which the tear bars may ultimately be torn. All of the cuts which form the joining means extend in or below the severance plane.
