ABSTRACT:
The present invention is a reclosable carton in the form of a rectangular box, having opposed parallel substantially single layer front and rear walls, opposed parallel substantially single layer side walls and a closed bottom end forming a carton body. The carton includes a top end flip-top reclosable hood. The hood includes a hood skirt and is formed by an outside main hood panel foldably connected to the carton body, an inside hood panel foldably and severably connected to the front carton wall and including a transverse fold line defining a front hood skirt panel, and two minor hood forming flaps foldably and severably connected to the carton side walls and foldably connected to the inside hood panel. The transverse fold line extends collinearly across the side panels and the carton is provided with an opening tear strip extending completely across the hood forming panels and flaps and parallel to the transverse fold line. The invention provides a friction group of panels to enhance the frictional engagement between the hood and the carton body to ensure that the hood remains closed after it is opened and reclosed, yet prevents the outermost fold score lines associated with the skirt from expanding outwardly and rupturing.
