Abstract
A closure according to the present invention includes an annular inner member defining an opening, the inner member having a camming recess. The closure also includes an outer member engageable with the inner member, the outer member including a lid base, a lid hingably connected to the lid base, and an annular guard ring surrounding the lid and lid base. The annular guard ring is frangibly connected to at least one of the lid and lid base, preferably along a frangible line formed by a plurality of bridges. The outer member can be formed integrally as one piece. When the inner member and outer member are joined, the guard ring preferably separates from the lid and lid base, and the lid base is at least partially retained within the camming recess. Once separated from the lid and lid base, the guard ring is movable between a guarding position in which it obstructs access to the lid, and a revealing position in which the lid can be rotated upward, away from the opening.
