Patent ID: 8371463

Claim:
A child-resistant canister comprising a container formed to include a product-receiving chamber and a mouth opening into the product-receiving chamber, a closure including a lid comprising a wall formed to include an interior region and configured to mount on the container to assume a closed position closing the mouth formed in the container when rotated relative to the container about an axis of rotation, and a closure-release control mechanism comprising a first lock tab spaced radially inwardly of the lid wall and coupled to the lid of the closure and arranged to lie in the interior region formed in the lid and a first tab controller coupled to the container and formed to include a lock-tab receiver channel arranged to receive the first lock tab therein when the closure is mounted on the container to assume the closed position, wherein the first tab controller includes a tab blocker configured normally to mate with the first lock tab upon movement of the first lock tab to a closure-retaining position in the lock-tab receiver channel to block rotation of the closure relative to the container about the axis of rotation in a closure-removal direction to retain the closure in the closed position on the container and a tab-motion limiter configured to provide means for blocking movement of the first lock tab in a radially outward direction away from the axis of rotation to unmate from the tab blocker during an unauthorized attempt to remove the closure from the container so that an unauthorized user is unable to move the first lock tab from the closure-retaining position in a radially outward direction to assume a radially outwardly displaced position unmated from the tab blocker and then rotate the closure relative to the container about the axis of rotation in a closure-removal direction while the first lock tab remains in the radially outwardly displaced position to cause the first lock tab to move relative to and past the tab blocker without mating with the tab blocker in an unauthorized effort to remove the closure from the container.
