ABSTRACT:
Self-contained reusable pour spout structure is made by means and methods compatible with low-cost bag production machinery and methods. Thus, a memory strip with an internal metallic strip and an external cover compatible with attachment to the bag material by heat welding, gluing or sewing, is simply placed at a desired access opening position, attached along its length on one bag layer and attached at opposite ends to two bag layers with the intervening distance unattached to the second bag layer. This strip then is manually deformed into a bowed position to open the spout and is straightened to close the spout over a plurality of use cycles. The bags so made are useful for containing and dispensing candy, cereal and like products.
