Abstract
The package generally includes at least one front and back panel joined at least partially together to define an interior accessible through an access opening. The interior is capable of storing and dispensing product and other objects or materials. Further, at least one web member can be joined to each of the front and back panel portions respectively to form at least two generally parallel chambers and/or channels that extend generally along at least a portion of the access opening. In one embodiment, each of the chambers includes a reservoir or storage portion and a closure portion in fluid communication such that either the reservoir portion or the closure portion are generally inflated or expanded to correspondingly close or open the access opening.
