Patent attributes
A bag has a recloseable fastener, a bottom and, for each side, a flap. The flap has side edges that are sealed to side edges of the bag, the flap being sized and dimensioned such that the flap lies flush against the side of the bag except when stretched or drawn apart therefrom, the flap being disposed intermediate the recloseable fastener and the bottom. The fastener is adapted such that the amount of force necessary to separate the components, when such force is applied to interiors of the walls at a position between the fastener and the bottom and adjacent the fastener, is greatly exceed by the amount of force necessary to separate the components: when such force is applied to the walls adjacent the upper edge; and when such force is applied to the free edges of the flaps. The bag can be produced either on a pouch machine or a sideweld bag machine. A single web can be fed over a series of rollers and formers to make progressive folds and a zipper closure can be continuously fed to the inner side of the structure and sealed in place. Side seals are made intermittently to finish the bag. The seal on a sideweld version can be a bead seam whereas on the pouch machine the seal can be up to ¼″ wide.
