Abstract

A closure configured to be engaged with a container, wherein the closure includes a cap and a twist ring. According to aspects of the disclosure, the cap may include: a generally cylindrical main body, a lid, a sidewall extending substantially perpendicularly from the lid, a hinge which allows the lid to pivot between a closed position and an open position, and a lift tab configured to protrude outwardly from the cap. According to aspects of the disclosure, the twist ring may be configured to extend around the cap. Further the twist ring may include: a generally cylindrical main body, a rim extending in a substantially horizontal plane and a sidewall extending substantially vertically from the rim. According to aspects of the disclosure, the twist ring may be configured to be rotated in order to be positioned to selectively prevent the lid of the cap from being pivoted from the closed position to the open position.
