Abstract: A dispenser package and outlet forming structure include a package wall (20) and a flap (30). Flap (30) is folded over at any desirable location of the package (10) and is adhesively attached to the package wall (20) at any predetermined location. Flap (30) is folded so that the surface of flap (30) that is adhesed to the surface of the package wall (20) is one continuous surface. When a pulling force exerted by a user exceeds the adhesion force between the package wall (20) and the flap (30), the flap (30) will break away from the package wall (20) causing a locus, fault, or score (40) to rupture. The rupturing of the locus, fault, or score (40) also causes the aperture outlet (50) to rupture thereby forming an outlet hole at a predetermined location for allowing the flowable product contents to exit the package (10).
