TOP-FILLED TAMPER-EVIDENT PACKAGE

摘要

A fastener for a top-filled tamper-evident reclosable plastic package is disclosed. The package includes first and second opposing panels joined along a pair of sides and a bottom bridging said sides. The fastener includes first and second opposing tracks along a top of the package. The first and second tracks include respective first and second interlocking profiles and respective first and second fins extending from the respective first and second profiles. The first and second fins are joined to each other at their respective lower ends. A preferential area of weakness is disposed along or near the juncture of the first and second fins. While the fastener is attached to the first panel, the fastener initially is at least partially unattached to the second panel so as to allow the package to be filled with a product via a fill opening between the fastener and the second panel. After filling the package with the product, the fill opening is sealed. The fastener includes special structure added proximate the fins to prevent the fins from being deformed, being stuck to each other, or being accidentally sealed to each other while sealing the fill opening.
