A flip-top closure includes first and second closure portions. The first closure portion includes a top wall portion with a tamper-evident winged section and a middle section, which are connected via a frangible connection. The winged section forms an undercut. The top wall portion includes a drivable structure to assist in threading the flip-top closure into a container. The second closure portion includes an annular skirt portion and a ledge. The annular skirt portion forms an external thread formation. The ledge includes at least one locking protrusion. A hinge connects the first and second closure portions. In an initially closed position, the undercut of the winged section corresponds with and lockingly engages with the locking protrusion. During movement of the hinge from the initially closed position to an open position, the frangible connection breaks leaving the winged section being lockingly engaged with the locking protrusion.

Flip-top closure and a package

A container assembly includes a container and a lid. The container has a sidewall, a bottom and a flange. The sidewall includes a child-resistant release tab that moves towards the sidewall. The release tab forms an opening therein. The flange includes ramp projections. The lid includes a top portion and opposing retention sidewalls. The retention sidewalls include a stop projection. An interior surface of the polymeric slidable lid includes a sealing liner. The stop projection and the release tab assist in preventing or inhibiting movement of the container assembly from a closed to an open position. After the release tab is moved towards the sidewall, the lid can slide from a closed to an open position. The lid contacts the ramp projections resulting in further movement of the lid into a different axial plane spaced above the flange.

Child-resistant container assembly

A closure for use with a container in which the closure includes a polymeric top portion and a polymeric annular skirt portion. The skirt portion depends from the top portion. The skirt portion includes exterior and interior surfaces. The interior surface of the skirt portion includes crushable ribs and anti-rotational lugs. The crushable ribs are configured to be crushed when the closure is applied to the container so as to prevent or inhibit axial movement of the closure with respect to the container by forming an interference fit. At least one of the plurality of anti-rotational lugs prevents or inhibits rotational movement of the closure with respect to the container such that the closure remains on the container.

Anti-rotational and removal closure

A package includes a container and closure. The container has a neck portion defining an opening. The container has an external thread formation and catch lugs. The closure fits to the neck portion for closing the opening. The closure includes first and second closure portions. The first closure portion includes a top wall portion and a skirt portion. The skirt portion depends from the top wall portion. The skirt portion includes an internal thread formation for mating engagement with the external thread formation. The second closure portion includes a tamper-evident band depending from and being partially detachably connected to the skirt portion by a frangible connection. An interior surface of the second closure portion includes catch teeth. The catch lugs mechanically catch and lock with a respective one of the catch teeth to prevent or inhibit the second closure portion from being removed during the opening of the container.
