Abstract
A package having a hollow interior for holding material therein. The package is formed of flexible sheet material and comprises a pair of panels connected by respective side gusset folds, a mouth located between the side gusset folds and communicating with the interior of the package, and a pair of notches and associated seals. Each of the folds comprises a central fold edge interposed between a pair of outer fold edges and defining therebetween respective gusset sections which are subadjacent the respective panels. The mouth of the package is sealed to hold the material within the interior of the package isolated from the ambient atmosphere. Each notch is formed in a respective one of the outer fold edges and the panel and gusset section contiguous therewith. The seal is air-tight and surrounds the associated notch to join the panel and contiguous gusset section to each other to preclude air from entering into the interior of the package through the notch. The notches enable the package to be torn open therefrom to form a pouring spout through which free flowing grannular products can be poured at a controlled rate.
