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. 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. When the flexible pouch is in an inflated condition, communication is preferably closed between each inner inflatable chamber and each outer inflatable chamber, and the inner inflatable chamber is at least partially inflated, for providing even more rigidity. Increased rigidity is particularly beneficial when using a straw or fill tube inserted within the channel for the purpose of holding or otherwise displaying the inflatable flexible pouch.
