Abstract
Disclosed is a dispensing closure for product packaging, having a closure body that attaches to a container, and a toggle dispensing lid with an integral locking switch attached to the closure body. An integral frangible tab, which must be fractured before the closure can be used to dispense product, may be included for tamper evidence. The integral locking switch has at least two living hinges so that it may be moved between locked and unlocked positions, thereby permitting movement of the dispensing lid between closed and product dispensing positions.
