ABSTRACT:
A pouch is formed out of two sheets of plastic heat sealed over most of the edge length. The pouch has an expanding bottom feature and has a pouring spout formed by raised impressions in the corresponding sheets of plastic that form matching embossments. When the pouch is squeezed, the embossments open further apart to form a larger fluid passage at the outlet. The outlet of the pouch is opposite the bottom of the pouch and in at least one embodiment has a region on both sides of the outlet that are kept free from heat sealing during manufacture. The outlet also has a frangible line of weakness for easy opening. The outlet passage has two sets of embossments that meet along a center line to more fully expand the central portion of the pouch.
