Abstract: The present invention relates generally to the field of closure devices for consumer products, including both liquid and dry products. More specifically, the present invention relates to a lid or closure for consumer goods packaging that provides a secure locking engagement to prevent spilling, leakage, and/or tampering of the contents of the packaging. The unique closure device utilizes a combination of a release tab and locking elements, which cooperate with one another in order to seal or unseal at least a portion of the lid or closure to allow for dispensing of the contents of the container.
