Abstract

An inflatable flexible pouch having two inner webs positioned between two outer webs. The two inner webs are attached to each other so as to form a channel between both inner webs. Each outer web and each inner web forms a body portion and a neck portion or throat opening. A first outer web is sealably attached to a first inner web and a second outer web is sealably attached to a second inner web, both sealed attachments are positioned at least partially across the neck portion or throat opening of the aligned webs. The outer webs and the inner webs are sealably attached about a general periphery of the body portion and along both side sections of the neck portion or throat opening. A throat opening is formed within the neck portion between both inner webs and such throat opening is in communication with the channel and with an ambient atmosphere which is external to or surrounds the inflatable flexible pouch. At least one inner inflatable chamber is formed between both inner webs and positioned within the outer inflatable chamber for providing increased rigidity of the inflated pouch structure.
