Reclosable bag having double closure
摘要:
A reclosable bag having two spaced-apart flexible closures and external finger guide ridges and/or pressure distribution ridges to facilitate their closure. The ridges lie in a region between the double closures and they extend generally parallel to each other and to the closures when the bag is in an empty and flat state. The pressure distribution ridges improve the finger pressure distribution by moving the applied forces closer to the closure profiles. When used in conjunction with external finger guide ridges, the pressure distribution ridges also improve the bearing surface of the external finger guide ridges with the thumb and forefinger of the person closing the bag.
