One piece, push button, flip top closure

A push button, flip top closure for a container, which comprises:

• a base portion, the base portion including a side wall, the side wall having a notch formed therein;
• a push button actuator situated on the base portion and pivotally mounted thereon to pivot with respect to the base portion;
• a central cap having an orifice formed through the thickness thereof, the push button actuator at least partially surrounding the central cap;
• and
• a lid having a lower surface and being hingedly mounted to the base portion and positionable between at least a closed position to cover the orifice formed in the central cap and an open position to uncover the orifice formed in the central cap, the push button actuator selectively forcing the lid to pivot to the open position to allow the contents of the container on which the closure is mounted to pass through the orifice in the central cap;
• wherein the push button actuator includes a finger engagement portion, the finger engagement portion being situated in alignment with the notch formed in the side wall so as to be exposed thereby to allow a user to press the finger engagement portion of the push button actuator to pivot the lid to the open position, the push button actuator being generally U-shaped and including a pair of spaced apart arms situated opposite the finger engagement portion, the central cap being situated between the pair of spaced apart arms;
• and wherein each arm of the pair of spaced apart arms includes a free end, and the lid includes a pair of camming protrusions extending outwardly from the lower surface thereof, each camming protrusion of the pair of camming protrusions being disposed on the lid in alignment with a free end of a respective arm of the pair of spaced apart arms, each camming protrusion of the pair of camming protrusions having a camming surface formed thereon, the camming surface of each camming protrusion being engageable by the free end of the respective arm of the pair of spaced apart arms so that, when the exposed finger engagement portion of the push button actuator is pressed by the user, the free ends of the arms of the pair of spaced apart arms of the push button actuator exert a force on the camming protrusions to cause the lid to pivot to the open position to uncover the central cap and the orifice formed therein.
