Abstract

A method of forming and filling a pouch, comprises forming opposing walls of a film; sealing the opposing walls of film together to form at least one pouch; filling an interior section of the at least one pouch through an opening in an upper portion of the at least one pouch with a flowable material; forming a top sealed expressing-shaped region to close the opening in the at least one pouch; and cradling the pouch with a foldable flat that is more rigid than the pouch that can be folded or rolled to compress the pouch to express the flowable material through the expressing shaped region.

First claim

1 - 25 . (canceled)

26 . A packet for dispensing a viscous material enclosed therein, comprising:
a rigid flat having opposing edges; opposing first and second sidewalls connected to form a flexible pouch having opposing first and second closure ends; a spout forming area having a tip end at one end and integrally connected at the other end to the first closure end of the flexible pouch such that upon the compression of the flexible pouch the viscous material is expressed through the tip, wherein the flexible pouch supports an entire surface area of one sidewall of the filled pouch, except for an expressing-shaped region of the pouch, and is cradled to the rigid flat and within the opposing edges of the rigid flat such that over-folding of the opposing edges compresses the flexible pouch to express the viscous material.
