Abstract
A closure including a base and a cap that pivot with respect to each other. The front portion of each of the base and cap are detachably coupled together via a series of frangible connections that break sequentially when the closure is opened. The plurality of frangible connections have different configurations to increase a total amount of time between the time when the first frangible connection breaks and when the last frangible connection breaks.
Claims20
A closure comprising:
- an axis;
- a top panel centered on the axis;
- a first cylindrical wall extending downward from the top panel, the first cylindrical wall centered on the axis;
- a hinge extending from and coupled to a rear portion of the first cylindrical wall;
- a second cylindrical wall centered on the axis, the second cylindrical wall pivotally coupled to the first cylindrical wall via the hinge, the first cylindrical wall and top panel pivoting with respect to the second cylindrical wall via the hinge between an open position and a closed position;
- a securing element extending from the second cylindrical wall, the securing element configured to couple the second cylindrical wall to a container neck of a container;
- a first frangible connection coupling the first cylindrical wall to the second cylindrical wall, the first frangible connection providing evidence, when broken, that the closure has been opened, the first frangible connection extending circumferentially around the axis a first circumferential distance;
- and
- a second frangible connection coupling the first cylindrical wall to the second cylindrical wall, the second frangible connection providing evidence, when broken, that the closure has been opened, wherein the second frangible connection is closer to the hinge than the first frangible connection, the second frangible connection extending circumferentially around the axis a second circumferential distance, and wherein the second circumferential distance is greater than the first circumferential distance.
