Abstract
Official abstract text for this publication.
Tear-open pouches having a first panel and a second panel sealed to one another at a non-peelable or peelable perimeter seal defining a compartment having a first compartment area of the first panel and a second compartment area of the second panel with a score disposed on the first panel extending from a first position in the perimeter seal along a first direction that extends across the first panel and into the first compartment area. An optional second score can be disposed on the first or second panel and extend from a second position in the perimeter seal along a second direction that extends across the first or second panel and into the first or second compartment area and the second position can be adjacent to the first position, and the first and second directions can be divergent to one another.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tear-open pouch comprising a first panel and a second panel sealed to one another at a perimeter seal defining a perimeter of a compartment of a pouch and defining a first compartment area of the first panel and a second compartment area of the second panel; and a first score disposed on the first panel and extending from a first position in the perimeter seal along a first direction that extends across the first panel and into the first compartment area of that panel; and a tearing aid disposed in the perimeter seal extending through the thicknesses of the first and second panels, the tearing aid comprising a notch having a first end and a second end opposite the first end, the first end and the second end being spaced from outer edges of the pouch, wherein the first score extends from the tearing aid; wherein the second panel is free of a score; and wherein the first position is adjacent to a corner of the perimeter seal such that when the first score is torn, the second panel contains at least one layer of oriented polymer and forms a tear in a second direction along an inside edge of the perimeter seal, and the first and second directions being divergent to one another. 2. The tear-open pouch of claim 1 , wherein the first panel is free of a score that is aligned with and opposing the inside edge, and the second panel is free of a score that is aligned with and opposing the first score. 3. The tear-open pouch of claim 1 , wherein the first score extends along a majority of a length of the pouch. 4. The tear-open pouch of claim 1 , wherein the first score extends linearly. 5. The tear-open pouch of claim 1 , wherein the first score extends arcuately. 6. The tear-open pouch of claim 1 , wherein the perimeter seal is non-peelable. 7. The tear-open pouch of claim 1 , wherein the perimeter seal is peelable.
