ABSTRACT:
A dispenser package for flowable substances of the type where the flowable product is contained within a flexible pouch adhered to a relatively stiff sheet material which is opened along a fault line or fault pattern with one hand by folding the stiff ends toward one another into a "V" shape, wherein the flexible product-containing pouch is formed with a shallow duct or channel area directly behind the fault line connecting two laterally spaced pockets located on either side of the fault pattern to eliminate squirting or "spitting" of the flowable product upon rupture of the fault line or fault pattern. The stiff sheet material also may contain one or more protrusions displacing at least a portion of the fault line out of the plane thereof, the protrusions comprising substantially pyramidal shapes having either straight-lined or curved profiles.
