A dispenser comprising a body with an outlet, and a closure for the outlet; - the closure being pivotally interconnected at the body by a first pivotal interconnection such that the closure is movable relative to the body between an open position in which the outlet is open and a closed position in which the closure closes the outlet; - the closure and the body being further adapted for locking engagement with each another in the closed position; - in which the closure and the body are interconnected by a bistable hinge being adapted to automatically urge the body and the closure from an intermediate position between the open and closed position toward the open or closed position; characterized in that - the closure having a locking member that is movable relative to the closure between a lock position allowing for locking the closure with the body in the closed position, and an unlock position providing for unlocking the closure for movement from the closed toward the open position; - the locking member having an actuator for moving the locking member between the lock and the unlock position; - the actuator and the body being arranged relative to the first pivotal interconnection such that a force applied on the actuator relative to the body for moving the locking member toward the unlock position also urges the closure toward the open position; - the dispenser having an inlet for receiving material to be dispensed from a container, the inlet being arranged opposite of the outlet, the dispenser having a longitudinal axis extending through the inlet and the outlet, wherein the locking member extends generally parallel to the longitudinal axis; - wherein the actuator forms a free end of the locking member, and wherein the locking member is oriented such that the actuator extends toward a direction substantially corresponding to a direction from the inlet toward the outlet. - the closure being pivotally interconnected at the body by a first pivotal interconnection such that the closure is movable relative to the body between an open position in which the outlet is open and a closed position in which the closure closes the outlet; - the closure and the body being further adapted for locking engagement with each another in the closed position; - in which the closure and the body are interconnected by a bistable hinge being adapted to automatically urge the body and the closure from an intermediate position between the open and closed position toward the open or closed position; characterized in that - the closure having a locking member that is movable relative to the closure between a lock position allowing for locking the closure with the body in the closed position, and an unlock position providing for unlocking the closure for movement from the closed toward the open position; - the locking member having an actuator for moving the locking member between the lock and the unlock position; - the actuator and the body being arranged relative to the first pivotal interconnection such that a force applied on the actuator relative to the body for moving the locking member toward the unlock position also urges the closure toward the open position; - the dispenser having an inlet for receiving material to be dispensed from a container, the inlet being arranged opposite of the outlet, the dispenser having a longitudinal axis extending through the inlet and the outlet, wherein the locking member extends generally parallel to the longitudinal axis; - wherein the actuator forms a free end of the locking member, and wherein the locking member is oriented such that the actuator extends toward a direction substantially corresponding to a direction from the inlet toward the outlet.
