A resealable closure (11) for a container (10) in which package integrity is indicated by a structure which breaks and/or produces an audible sound when the resealable closure (11) is opened for a first time. The package integrity feature, in one form includes at least one strip (50,52,54) initially affixed to two portions which comprise the resealable closure so that upon opening the resealable closure for a first time, at least one of the strips (52) breaks, thereby producing the audible sound. The strips may include a weakened portion such as a narrowing (52c). Integrity of the package is indicated by an intact strip viewable upon opening the resealable closure and conversely, a broken or non-intact strip would indicate that the resealable closure has been previously opened. Package integrity may also be shown by a movable second panel (42) or movable die cut tab portions (25). |
