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 material and may be opened along a fault line or cut pattern scored in the relatively stiff material with one hand by folding the stiff ends toward one another into a "V" shape containing one or more dimples, pyramidal shapes or other protrusions on the fault line or fault area. The protrusions not only increase and concentrate the stress forces, so that even very tough, high barrier materials may be used in constructing the package and will rupture at the protrusions by the aforesaid folding motion, but also control both the aperture shape and flow direction of the flowable substance as it is dispensed. The ability to make the package of tough materials enables the package to contain substances under pressure which subsequently will be dispensed. A sponge-like material also may be compressed within the package shaped so that a portion will project from the package on opening for use as a swab for application of the contents.
