<p>A reusable closure device is secured to an engagement member on the nozzle of a container. The device has a stopper which can partially abut the nozzle. The stopper is connected by one or more hinge members to a sleeve. The sleeve has a retaining member which engages the engagement member. The hinge members allow the stopper to pivot about the nozzle from a closed position, which forms a leak-proof and air tight seal, to an open position, which allows access to the container contents.</p> |
