Abstract
Abstract This invention relates to a flexible bag having a front panel and back panel forming the envelope with the same joined at the bottom and sides thereof has a strip of pressure-sensitive adhesive tape adhered by the adhesive to the inner surface of the front panel with a portion thereof extending above the front panel. The exposed adhesive on the tape affords means for adhering the bag to the edge of a counter or surface, and the same will form means for securing a flap on the bag over the opening. Notches at the sides of the bag adjacent the opening permit greater separation of the front and back panels to increase the size of the opening without separation of the tape.
