Abstract
A dispenser closure is provided having a stopping mechanism that limits the rotation of the closure and generally prevents removal of the closure cap from the container. The dispenser closure includes a cap body, fitment and container finish. The cap body has a double shell design, which includes at least one drop lug projecting from the inner shell. When the cap body is rotated about the container finish, the drop lug engages at least one lug stop located on the container finish so as to limit the rotation, thereby preventing removal of the cap body from the container finish.
