发明名称 Tamper-evident easy-open slider package and related methods of manufacture
摘要 A reclosable packaging having a slider/zipper assembly and a sealed header. The header has a tear notch for initiating tearing of the header material and a line of weakness for continued tearing of the header material at an elevation which is lower than the top of the slider. Most preferably, the line of weakness is lower than the bottom of the slider. When the header is torn along the line of weakness, at least part of the slider is exposed and accessible to the consumer. In one embodiment, the tear notch is located in a side edge at an elevation higher than the top of the slider. A slit is provided which traverses a range of elevations encompassing a first elevation near an elevation of the tear notch and a second elevation near an elevation of the line of weakness.
