Shrouded flexible packages
View Patent ↗A shrouded flexible package is provided with an improved continuous laser score line. The score line has end portions adjacent the side seals of the package, which are located above fastener tracks which are enclosed by a shroud portion of the package. The score line contains downwardly and inwardly converging segments joined to a medial score line segment extending along side and generally below the fastener tracks. The score line is preferably formed with a laser energy source.
1. A reclosable package comprising:
first and second panels having opposed top and bottom ends, opposed lateral sides joined together by side seals, said first and said second panels comprising upper shroud portions and lower sidewall portions cooperating to form an interior cavity of said reclosable package;
first and second interlocking fastener tracks carried on said first and said second panels, respectively, so as to be spaced from their top ends, the fastener tracks extending from the side seal of one of the opposed lateral sides to the side seal of the other of the opposed lateral sides;
a slider movable along said fastener tracks for locking and unlocking said fastener tracks;
end stops formed in said fastener tracks adjacent said side seals and inwardly therefrom;
a continuous laser score line formed in each of said first and said second panels to separate the shroud portions from the sidewall portions of said first and said second panels, said score lines extending adjacent said lateral sides at a point above said fastener tracks, downwardly across said fastener tracks at an incline after clearing said end stops and alongside said fastener tracks, so that with rupture of said score lines said shroud portions are removed, exposing said slider and said fastener tracks.
2. The package of claim 1 further comprising cutouts in said side seals communication with said score lines.
3. The package of claim 1 wherein said score lines comprise straight line segments.
4. The package of claim 1 wherein, with said shroud portions removed, portions of said first and said second panels cover end parts of said slider and said fastener tracks adjacent said side seals.
5. The package of claim 1 wherein said score lines extending downwardly across said fastener tracks at an incline of approximately 45 degrees to the side seals.
