A self-expanding flexible pouch that can be used as the measuring device for reconstituting a concentrated product contained therein. The flexible pouch includes an extensible stay located in the throat area of the pouch that is biased toward a circular or elliptical configuration but initially held substantially flat in a stressed condition by the pouch\s sealed top portion. When the pouch\s top portion is removed, the extensible stay expands to its unstressed circular configuration and thereby expands and opens the pouch\s throat area. In a particularly preferred embodiment of the present invention, the pouch\s bottom section is provided with a pleated bottom gusset panel that is attached to the sidewall panels\inner surface. When the reconstituting fluid is poured into the pouch, the pouch\s bottom gusset panel unfolds and drops downward which allows the pouch\s bottom section to also expand and assume a substantially tubular configuration. Also disclosed are various barrier laminates from which pouches of the present invention can be made which protect the pouch\s contents from light, moisture, and air, and also resist the absorption of essential oils, flavoring components, and nutritional elements found in the product contained within the pouch.
