TAMPER-EVIDENT REUSABLE PACKAGE CLOSURE

摘要

A reusable closure system is disclosed for packaging applications. The closure system generally includes a base and hinged lid. The base is bondable to a package and includes a field of touch fasteners having one or more cut-lines therein defining a hinged pull-tab assembly. The lid comprises a complementary touch fastener field and can be placed in the open position to expose the pull-tab assembly, which can then be peeled back to open the package by virtue of the bond between the pull-tab assembly and a frangible region in the package. After opening, the pull-tab assembly can be stowed to the lid, so as to provide a lid-based plug corresponding to the package hole. Optional tamper-evident elements allow a consumer to see the package has not yet been opened. Stay-open lid and anti-peel mechanisms may also be provided. A dispensable roll/fanfold of the closures can feed a flow-wrap packaging process.

主权项

1. A reusable closure system, comprising:
a base configured to be bonded to underlying package material and including a first field of touch fasteners having one or more cut-lines therein defining a hinged pull-tab assembly; and a hinged lid configured for movement between open and closed positions relative to the base and including a second touch fastener field that is complementary to the first touch fastener field, such that the first and second touch fastener fields engage with one another to provide a secure closure when the lid is in the closed position; wherein upon opening of the lid, the hinged pull-tab assembly is exposed so that the pull-tab assembly can be peeled back to its hinge while simultaneously removing a frangible region of the packaging material to which the base can be bonded, and so that the peeled-back pull-tab assembly can be securely stowed against the lid by operation of the first and second touch fastener fields thereby providing a lid-based plug configured to engage the resulting hole in the packaging material when the lid is in the closed position.
