Abstract
A plastic dispensing closure includes an elongated dispensing spout that defines an interior passage and has a distal end terminating in a rim. A sealing member is integral with the dispensing spout and is frangibly connected to the distal end of the dispensing spout by frangible connecting structure in order to seal the interior passage and prevent fluid from leaking out of the closure before it is opened. A lever arm that is integral with the sealing member is oriented so as to extend upwardly from the sealing member. The frangible connecting structure is advantageously constructed and arranged to rupture when a predetermined torque is applied to the lever arm. The predetermined torque is calculated so as to minimize the likelihood of the closure being opened accidentally, while at the same time being convenient for a consumer to open.
