US Patent 9352886 Trapped element security container

A container has features to indicate tampering and to discourage reuse as a deterrent to use with counterfeit goods. A lid hinged to a thermoformed thermoplastic base defines a product compartment. A line of weakened material surrounds a retention tab within a base upper wall. The tab is secured to a lid upper wall such as by a weld. The retention tab is secured to the lid through an opening in an enclosure element such as a card of thermoformed sheet. When the lid is separated from the base the retention tab is detached from the base along the weakened line of material and retained by the secured connection to the lid with the enclosure element retained by the retention tab to the lid upper wall. The retention tab interferes with the removal of the enclosure element from the lid and its reuse with counterfeit goods.
