发明名称 Reclosable package having an accessible zipper and a method for making the same
摘要 A reclosable package includes a tray, a top sheet, and a fastener. The tray has a well for receiving contents and a peripheral flange surrounding the well. The top sheet is attached to the peripheral flange. The fastener has two interlocking members, one attached to the peripheral flange and the other attached to the top sheet. A tamper-evident feature located on the package prevents access to the fastener and is connected thereto by one or two lines of weaknesses. In one embodiment with one or two lines of weakness in the top sheet, the fastener remains adjacent to the tray's peripheral flange, which is intact after the tamper-evident feature is removed by tearing along these lines of weakness. In a second embodiment with two lines of weakness, the tamper-evident feature, comprised of portions of the peripheral flange and the top sheet, is torn from the package along both lines of weakness.
