Abstract
A child-resistant closure is provided with a base having a deck with a discharge aperture. A lid having a bottom surface for engaging the base is hingedly connected to the base. The base has a resilient locking lever that projects the base deck at a location inwardly of the periphery of the base. The lever defines a shoulder. The lid has a central cover panel defining an aperture inwardly of the periphery of the lid for receiving the lever when the lid is closed. The lid defines a latch surface adjacent the aperture for confronting the base lever shoulder when the lid is closed. The periphery of the lid defines a finger-engaging surface laterally offset relative to the lid aperture, and the finger-engaging surface extends progressively outwardly with increasing distance from the lid bottom surface. The portion of the base that extends from the hinge connection is configured to project peripherally outwardly at least as far as the lid bottom surface when the lid is closed. The portion of the lid periphery that extends from the hinge connection is free of overhanging peripheral surfaces of sufficient depth to be liftingly engaged by a child's teeth.
