Tamper-evident closure device for containers with flowable material
A newly granted patent (Publication Number: US11993426B2) discloses a closure device for containers storing flowable materials. The device includes a base element, a spout with a dispensing opening, and a lid connected to the base element by a hinge. What sets this closure device apart is the tamper evidence indication means, comprising a first indication ring and at least one second indication ring connected by frangible bridges. These bridges are designed to be disrupted when the lid is moved from the closed position, causing an axial movement of the indication rings relative to each other, visually indicating if the lid has been tampered with. The design ensures that the indication rings are coaxially positioned and have an axially overlapping section before and after the lid is moved from the closed position.
Furthermore, the closure device features additional elements such as a spout sealing ring on the lid, interlocking means for fixing the indication rings, and a base element with a flange defining a pass-through duct for the spout. The device is constructed to provide tamper evidence without direct contact with the surrounding environment, enhancing the security of the container contents. The tamper evidence indication means are made from plastic materials using bi-injection molding, ensuring durability and reliability. Overall, the closure device offers a unique and effective solution for maintaining the integrity of container contents by providing clear visual indicators of tampering, enhancing consumer confidence in the product's safety and authenticity.
