ABSTRACT:
A package includes opposed flexible sides and a circumferential peripheral seal determining an interior sealed enclosure for storing a material, typically a viscous liquid. The package includes a depending seal which divides the enclosure into a storage reservoir and a dispensing channel in fluid communication. The dispensing channel includes an open upper end and a closed lower end, the upper end being in fluid communication with the storage reservoir, and the lower end being contiguous to the peripheral seal and to an aperture within the depending seal that is adapted to be torn open. Tearing the aperture results in collaterally tearing open the lower end of the dispensing channel and the contiguous portion of the peripheral seal, thereby enabling removal of package contents.
