ABSTRACT:
An improved flip-top recloseable carton is provided in the form of a six-sided parallelopiped enclosure having opposing top and bottom walls, front and back walls, and side walls formed from corresponding panels and flaps defined on a unitary, continuous paperboard blank. The outer layers of the side walls and the front wall are provided with horizontal tear-strip sections which define an integral and continuous tear strip that functions as convenient means for opening the carton from its sealed from. Repeated closing and positive locking of the carton is realized by means of a die-cut portion on the interior surface of the front wall which includes a proximal flap and an island portion dispersed in forcibly displaceable mutual engagement. Once the engaging flap and island are disengaged forcibly by opening the carton top, reclosing thereof leads to snap re-engagement of the flap and island elements accompanied by positive tactile and audible feedback indicative of effective carton closure.
