First Claim
1. A flip-top reclosable container comprising:
- an outer carton including opposing top and bottom walls, opposing front and back walls, and opposing first and second side walls, said first and second side walls and said front wall including a preferential area of weakness for opening said carton from a sealed form to an unsealed form, said preferential area of weakness forming a lid hingedly connected to said top wall, said top wall including a front top minor flap hingedly connected to an upper end of said front wall; and
an internal collar integrally formed with said front top minor flap, said internal collar disposed within said carton when said carton is in said sealed form, said internal collar including a front panel and opposing first and second side panels adjacent to said respective front wall and said opposing first and second side walls of said carton, said internal collar including an extension flap comprising at least one hinged portion and at least one island portion disposed in forcibly displaceable mutual engagement such that opening said lid exerts a force which disengages said mutual engagement and closing said lid leads to snap re-engagement of said hinged portion and said island portion.

Abstract
A one-piece, flip-top reclosable container embodying the present invention includes an outer carton having opposing top and bottom walls, front and back walls, and first and second side walls. The first and second side walls and the front wall include a preferential area of weakness for opening the carton from a sealed form to an unsealed form. The preferential area of weakness forms a lid hingedly connected to the top wall. The top wall includes a front top minor flap hingedly connected to an upper end of the front wall. An internal collar is integrally formed with the front top minor flap. The internal collar is disposed within the carton when the carton is in the sealed form. The internal collar includes a front panel and opposing first and second side panels adjacent to the respective front wall and the opposing first and second side walls of the carton. The front panel of the internal collar is detachably connected to the front top minor flap along at least one horizontal fold line. The internal collar optionally includes an extension flap comprised of at least one hinged portion and at least one island portion disposed in forcibly displaceable mutual engagement such that opening the lid exerts a force which disengages the mutual engagement and closing the lid leads to snap re-engagement of the hinged portion and the island portion.
