Dispenser package and outlet forming structure

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 ).
