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.

In a dispensing package for a flowable substance, said package including a relatively stiff substantially flat sheet and a flexible sheet secured to one face of said relatively stiff substantially flat sheet, said flexible sheet forming an enclosed pouch adjacent said one face of said relatively stiff substantially flat sheet for containing a flowable substance, said relatively stiff substantially flat sheet having a fault pattern of predetermined length whereby, upon bending said relatively stiff substantially flat sheet into a “V”about an axis extending along said fault pattern so that the arms of said “V”encapture said enclosed pouch, said fault pattern ruptures to create at least one opening through which said flowable substance is dispensed, the improvement therein which comprises: said enclosed pouch having a pair of enlarged product-containing pockets spaced laterally on either side of said fault pattern and a connecting wall extending between said pockets located directly behind said fault pattern, said connecting wall forming a shallow connecting channel area adjacent the back side of said relatively stiff substantially flat sheet, whereby, upon initial bending of said relatively stiff substantially flat sheet and prior to rupture of said fault pattern, said connecting wall is caused to flex into pressing engagement with the back side of said relatively stiff substantially flat sheet to thereby force flowable product out of said channel area and into each of said pockets.
