Abstract

The present invention provides a flexible storage bag having an opening, a closure system for the opening, and a closure indicator. The closure indicator may be provided by, at or near the edges of the bag which define the opening. For example, the edges may be sinusoidal in shape or have another irregular shape, such that misalignment of the edges occurs when the bag is open. Upon closing the bag, the edges substantially align and become generally colinear. Alternatively, the closure indicator may comprise a mechanical seal which becomes colinear upon closing. In an alternative embodiment, flaps may be juxtaposed with the closure system. The flaps encounter a change of position upon closure of the bag. The change in position may either be complete severance from the bag, or inflect from a first position to a second position upon closure or opening of the bag. Closure and/or opening of the bag may be accomplished by a slider.
