Abstract
A tamper-evident closure is provided with a base having a deck with a discharge aperture. A lid is included for covering the discharge aperture on the base. The lid defines a latch aperture. The base has a resilient locking lever that projects from the base deck and through the lid latch aperture when the lid is closed. The lever engages the lid and holds the lid closed. A tamper-indicating element is provided on the lid to prevent operation of the lever. The element is attached to the lid with frangible portions which can be broken when sufficient force is applied to remove at least a part of the element and permit operation of the lever whereby another part of the element remains on the lid to provide evidence that part of the element has been removed.
