    • 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.
    • 本发明提供了一种具有开口的柔性储存袋,用于开口的封闭系统和闭合指示器。 闭合指示器可以由限定开口的袋的边缘处或附近提供。 例如,边缘可以是正弦形的或具有另外的不规则形状,使得当袋打开时边缘的偏移发生。 在封闭袋子时,边缘基本上对齐并变得大致共线。 或者,闭合指示器可以包括在关闭时变为共线的机械密封。 在替代实施例中,折片可以与封闭系统并置。 襟翼在包装关闭时遇到位置的变化。 位置的变化可能是完全离开袋子,或者在关闭或打开袋子时从第一位置转移到第二位置。 袋的闭合和/或打开可以通过滑块来实现。
