Child-resistant canister
A child-resistant canister includes a container and a closure configured to mount on the container to close an opening into an interior region formed in the container. The closure includes a lid and a lid anchor coupled to the lid. The lid anchor is configured to mate with a closure retainer included in the container to retain the closure in a mounted position on the container.

a closure-release control mechanism comprising a lock tab coupled to the closure and a tab blocker coupled to the container and configured to mate with the lock tab upon movement of the lock tab to a closure-retaining position to block rotation of the closure relative to the container about the axis of rotation in a closure-removal direction to retain the closure on the container,
wherein the closure is formed to include a passageway extending through the closure between the first and second lid anchors and configured to allow movement of the lock tab in a radially inward direction toward the axis of rotation from the closure-retaining position to a closure-releasing position where the lock tab is positioned at a similar radial distance from the axis of rotation as the first and second lid anchors to separate the lock tab from the tab blocker and allow removal of the closure from the container,
wherein the first and second lid anchors are each formed to define at least one thread segment for engaging the container.
2. The canister of claim 1 , wherein the closure further includes a top wall and a tab-mover wall coupled to the top wall, and wherein the first and second lid anchors are coupled to the top wall on opposing sides of the tab-mover wall such that the first and second lid anchors are spaced apart from one another to define the passageway.
3. The canister of claim 2 , wherein the lock tab is coupled to the tab-mover wall and the tab-mover wall is configured to flex relative to the top wall to move the lock tab within the passageway.
4. The canister of claim 3 , wherein the tab-mover wall is spaced apart from the first and second lid anchors to define slots therebetween.
5. The canister of claim 4 , wherein the slot extends from the top wall to a bottom edge of the tab-mover wall.
6. The canister of claim 5 , wherein the closure has an inner diameter, a relatively larger outer diameter, and the ratio of the inner diameter to the outer diameter is greater than about 0.6.
7. The canister of claim 3 , wherein the tab-mover wall is connected to the first and second lid anchors by deformable webs.
8. The canister of claim 1 , wherein the closure has an opening diameter of about 28 millimeters, an inner diameter, a relatively larger outer diameter, and the ratio of the inner diameter to the outer diameter is in a range of about 0.64 to about 0.65.
9. The canister of claim 1 , wherein the lid anchors define an inner diameter of the closure and the lock tab is movable to a position radially inward of the inner diameter.
10. The canister of claim 9 , wherein the closure has an opening diameter of about 45 millimeters, an inner diameter in a range of about 1.6 inches to about 1.7 inches, a relatively larger outer diameter, and the ratio of the inner diameter to the outer diameter is in a range of about 0.74 to about 0.76.
11. The canister of claim 1 , wherein the closure is formed to define a beveled portion extending from the top wall and a substantially cylindrical portion extending from the beveled portion.
12. 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 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, the closure including a first lid anchor and a second lid anchor, the first and second lid anchors configured to engage with the container to retain the closure on the container, and
a closure-release control mechanism comprising a lock tab coupled to the closure and a tab blocker coupled to the container and configured to mate with the lock tab upon movement of the lock tab to a closure-retaining position to block rotation of the closure relative to the container about the axis of rotation in a closure-removal direction to retain the closure on the container,
wherein the closure is formed to include a passageway extending through the closure between the first and second lid anchors and configured to allow movement of the lock tab in a radially inward direction toward the axis of rotation from the closure-retaining position to a closure-releasing position where the lock tab is positioned at a similar radial distance from the axis of rotation as the first and second lid anchors to separate the lock tab from the tab blocker and allow removal of the closure from the container,
further comprising a floating liner coupled to the closure and located between a top wall of the closure and the first and second lid anchors,
wherein the first lid anchor is a thread segment having a first end located between the floating lid and the top wall and a second end opposite the first end located between the first end and floating lid.
13. The canister of claim 12 , wherein the first end is spaced apart from the top wall to locate the floating lid therebetween and engage the floating lid to block movement of the floating downwardly away from the top wall toward container.
14. The canister of claim 13 , wherein the container includes a filler neck formed to include the mouth, the filler neck having an outside diameter, and the floating lid having a diameter greater than the outside diameter of the filler neck.
15. The canister of claim 14 , wherein the closure has an opening diameter of about 53 millimeters, an inner diameter in a range of about 1.9 inches to about 2.0 inches, a relatively larger outer diameter in a range of about 2.5 inches to about 2.6 inches, and the ratio of the inner diameter to the outer diameter is in a range of about 0.77 to about 0.78.
16. 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 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, the closure including a first lid anchor and a second lid anchor, the first and second lid anchors configured to engage with the container to retain the closure on the container, and
a closure-release control mechanism comprising a lock tab coupled to the closure and a tab blocker coupled to the container and configured to mate with the lock tab upon movement of the lock tab to a closure-retaining position to block rotation of the closure relative to the container about the axis of rotation in a closure-removal direction to retain the closure on the container,
wherein the closure is formed to include a passageway extending through the closure between the first and second lid anchors and configured to provide means for allowing movement of the lock tab in a radially inward direction toward the axis of rotation from the closure-retaining position to a closure-releasing position where the lock tab is positioned at a similar radial distance from the axis of rotation as the first and second lid anchors to separate the lock tab from the tab blocker and allow removal of the closure from the container,
wherein the closure has an opening diameter of about 24 millimeters, an inner diameter in a range of about 0.86 inches to about 0.87 inches, a relatively larger outer diameter in a range of about 1.42 inches to about 1.43 inches, and the ratio of the inner diameter to the outer diameter is in a range of about 0.60 to about 0.61, and
further comprising a floating liner coupled to the closure and located between a top wall of the closure and the first and second lid anchors, the first lid anchor is a thread segment having a first end located between the floating lid and the top wall and a second end opposite the first end located between the first end and floating lid, and the first end is spaced apart from the top wall to locate the floating lid therebetween and engage the floating lid to block movement of the floating downwardly away from the top wall toward container.
