Abstract:
In a bag including first and second walls having joined opposing side edges, opposing end edges, and at least one seal line proximate one of said end edges and extending laterally from one side edge to the other for sealing closed an end of the bag, the improvement comprising a perforated tear line defining an easy-open corner portion of the bag removable to form a pourer, said perforated tear line comprising:(a) a vertical segment defined by a series of closely spaced perforations formed in said first and second walls of said bag and closer to one side edge of said bag than the other, said vertical segment extending in a straight path outwardly from said seal line and generally parallel to the closer side edge of said bag; (b) a first arcuate transition segment defined by a series of closely spaced perforations formed in said first and second walls of said bag, and beginning at an end of said vertical segment and extending in an arcuate path towards the closer side edge of said bag; and (c) a diagonal segment defined by a series of closely spaced perforations formed in said first and second walls of said bag, and extending along a straight incline from an end of said arcuate transition segment towards the closer side edge of said bag; (d) a second arcuate transition segment defined by a series of closely spaced perforations formed in said first and second walls of said bag, and beginning at an end of said diagonal segment and extending in an arcuate path towards the closer side edge of said bag; and (e) a horizontal segment defined by a series of closely spaced perforations formed in said first and second walls of said bag, and beginning at an end of said second arcuate transition segment and extending in a straight path towards the closer side edge of said bag; whereby said vertical segment, first arcuate transition segment, diagonal segment, second arcuate transition segment, and horizontal segment cooperate to enable the corner portion of the bag to be torn in a progressive tearing motion to form a hole in the bag from which the contents can be poured.
