Abstract:
A closure device for a reclosable plastic bag comprising:a first fastening strip; a second fastening strip arranged to be interlocked over a predetermined longitudinal X axis with said first fastening strip, said fastening strips have a transverse Y axis, said transverse Y axis is perpendicular to said longitudinal X axis, said fastening strips have a vertical Z axis, said vertical Z axis is perpendicular to said longitudinal X axis, said vertical Z axis is perpendicular to said transverse Y axis, said first fastening strip comprises a first closure element that extends from said first fastening strip along the transverse Y axis, said second fastening strip comprises a second closure element that extends from said second fastening strip along the transverse Y axis and which engages said first closure element when said fastening strips are occluded, said first and second closure elements having an occlusion and peel force; said first closure element including a first series of intermittent deformations disposed along its longitudinal X axis, each of said first series of deformations having a deformation component along the transverse Y axis thereby defining areas of compression in the first closure element; said second closure element including a second series of intermittent deformations disposed along its longitudinal X axis, each of said second series of deformations having a deformation component along the transverse Y axis thereby defining areas of compression in the second closure element and said areas of compression of second series of deformations being in substantially congruent and interdigitating relation with said areas of compression of said first series of deformations when said first and second fastening strips arc interlocked such that said occlusion and peel force is cycled intermittently over the length of the closure device.
