Abstract

Methods of opening and adding expansion materials to containers made from flexible materials. The methods involve forming a partially completed container blank that may have four layers of flexible materials. The partially completed container blank may be opened by separating a portion of the first layer from a portion of the second layer by bending portions of the second, third, and fourth layers toward a first direction; and dosing the partially completed container blank, by adding an expansion material out of a dispenser and into a space disposed between a portion of the first layer and a portion of the second layer.
