Abstract
A recloseable container comprises an outer carton and a liner constructed and arranged for placement within the carton. The carton includes opposing top and bottom walls, opposing front and back walls, and opposing first and second side walls. The first and second side walls and the front wall include a continuous horizontal tear strip for opening up the carton from a sealed form to form a lid hingedly attached to a base section. The liner includes a front panel and opposing first and second side sections for fitting the liner within the carton. The first and second side sections include respective first and second side panels having outer surfaces adjacent inner surfaces of the respective first and second carton side walls. Each of the first and second liner side sections includes a hinged portion and an island portion disposed in forcibly displaceable mutual engagement such that opening the container lid exerts a force which disengages the mutual engagement between the hinged portion and the island portion, and reclosing the lid leads to snap re-engagement of the hinged portion and the island portion.
