CONVERTIBLE CONTAINER CLOSURE
A convertible closure includes a lid and a lid-mover ring coupled to the lid. The lid is adapted to mate with a filler neck of a container to close an opening into the filler neck. The lid-mover ring can be used to rotate the lid in clockwise and counterclockwise directions to mate and unmate the lid and the filler neck. The convertible closure can be modified by a user to function in a child-resistant (CR) mode or a non-CR mode.

The present disclosure relates to container closures, and particularly to “child-resistant” container closures. More particularly, the present disclosure relates to “convertible” container closures that are configured to be used in a “child-resistant” (CR) mode or a “non-CR” mode at the option of a user.
SUMMARYA convertible closure in accordance with the present disclosure is configured to mate with a container to close an opening into a filler neck included in the container. The convertible closure is configured to be modified in the field by a user to function either in a “child-resistant” (CR) modes or in an easy-to-open non-CR mode.
In illustrative embodiments, the convertible closure includes a lid mounted for movement in an interior region formed in a surrounding lid-mover ring. The lid includes a base, axially upwardly extending torque-receiving lugs coupled to a ring-shaped platform included in the base, and radially outwardly extending torque-receiving teeth coupled to an annular side wall of the base. The lid-mover ring includes a shell, several downwardly extending lid-mover tabs coupled to the underside of an annular top rim included in the shell, and several inwardly extending lid-mover flanges coupled to an interior surface of an annular side wall of the shell.
When the closure is in the non-CR mode, the lid-mover flanges of the lid-mover ring always mate with the torque-receiving teeth of the lid during installation of the convertible closure on the container filler neck and removal of the closure from the container filer neck. In such a non-CR mode, the lid has been moved by a user relative to the surrounding lid-mover ring to assume a “lowered” position to cause the torque-receiving teeth of the lid to mate with the lid-mover flanges of the lid-mover ring during both clockwise and counterclockwise of the lid-mover ring about an axis of rotation relative to the container filler neck while the lid is mounted on the container filler neck.
When the closure is in the CR mode, the lid can be moved by a user relative to the surrounding lid-mover ring to assume either (1) a “raised” position (above the lowered position) to modify the closure so that the lid-mover ring can be rotated in a clockwise direction about the axis of rotation to cause the lid-mover tabs on the lid-mover ring to mate with the torque-receiving lugs on the lid during installation of the closure on the container filler neck or (2) an “elevated” position (above the lowered and raised positions) to modify the closure so that the lid-mover ring can be rotated in a counterclockwise direction about that axis of rotation to cause the lid-mover tabs to mate with the torque-receiving lugs during removal of the closure from the container filler neck. To remove the closure (in the CR mode) from the filler neck, it is necessary for the user first to apply an external “push-down” force to the lid-mover ring while the lid is mounted on the container filler neck to place the closure on the filler neck in the CR mode to cause the lid to move relative to the lid-mover ring from the raised position to the elevated position. Then the user rotates the lid-mover ring in the counterclockwise direction to cause the lid and lid-mover ring to rotate in unison about the axis of rotation in a closure-removal direction relative to the container filler neck. To install the closure (in the CR mode) on the filler neck, any rotation of the lid-mover ring by the user in the counterclockwise direction will cause the lid and lid-mover ring to rotate in unison about the axis of rotation in a cap-installation direction relative to the container filler neck.
