Tamper evident feature for container with locking tab and slot
A recently granted patent (Publication Number: US11919684B2) discloses a tamper-evident feature for containers, comprising a locking tab connected to the cover panel and a receiving slot in the wall panel. The locking tab includes an intermediate locking slit with tear-away lines and a terminal edge, while the receiving slot has a receiving slit and a receiving cut edge. When engaged, the intermediate locking edge aligns with the receiving cut edge, preventing removal without deformation. The design includes end fold lines, a ribbed extension portion, and curved shapes for enhanced security.
Furthermore, the patent extends to tamper-evident containers with multiple wall panels, a cover panel, and a bottom end construction. The tamper-evident feature includes a locking tab with tear-away lines, a ribbed extension portion, and an intermediate locking edge aligning with the receiving cut edge in the front wall panel's receiving slot. Once engaged, the feature restricts the cover panel's movement, ensuring tamper resistance. Additional features like end fold lines, curved shapes, and minor cut lines towards the upper edge of the front wall panel enhance the overall security of the container, providing a robust solution for tamper detection and prevention in various packaging applications.
