Abstract
At least one branched chamber extends and diverges from a side wall of a pouch body. The branched chamber has an optional pouring spout at its distal end to permit the removal of the contents of the pouch. A readily unsealable seal member is optionally included to partition the branched chamber from the pouch body, thus providing a pouch wherein two or more different materials are mixed prior to removal from the pouch. A pouch having this structure provides excellent rupture protection of the readily unsealable seal member caused from, for example, handling, shipping, or dropping of the pouch.
