Closure cap 214 can be formed without rim sealer 252 if the additional seal is not needed for certain applications. Rim sealer 252 engages with a rim of the neck of the container to form a contact seal with the neck. Plug wall 254 includes a free end 265, a flex section 251 and a plug mover 253 coupled to flex section 251. A sealer face 255 is defined along an outer perimeter of plug wall 254. Flex section 251 is coupled to second annular top wall 248 and configured to allow plug wall 254 to flex relative to second annular top wall 248. Plug mover 253 is configured to engage with the neck as closure cap 214 is being mounted on the container to flex plug wall 254 radially inward. Sealer face 255 of plug wall 254 engages with the neck to form a plug seal. In some embodiments, sealer face 255 remains engaged with the neck as rim sealer 252 becomes spaced apart from the rim of the neck as closure cap 214 is rotated relative to the container.

[0039] In the illustrative embodiment, second annular top wall 248 is further formed to include an inner annular plug groove 258 and an outer annular plug groove 259 as shown in Fig. 15. Inner plug groove 258 is located between sleeve 224 and plug wall 254. Plug wall 254 is located between inner plug groove 258 and outer plug groove 259. In one example, inner and outer plug grooves 258, 259 have a depth D ₃ into second annular top wall 248 of about 0.001 inches and 0.02 inches. In another example, depth D ₃ is about 0.01 inches to about 0.02 inches. Inner and outer plug grooves 258, 259 cooperate to maximize a length of plug wall 254 which maximizes torque applied to plug wall 254 during installation thereby minimizing vertical installation forced applied by the user. Inner and outer plug grooves 258, 259 effectively increase the length of the plug wall 254 without requiring plug wall 254 to extend further into the container. The additional length of plug wall 254 increases the flexibility of plug wall 254 by increasing the mechanical advantage due to an increase in length from a base 261 of plug wall 254 to a sloped face 263 of plug mover 25. In some embodiments, inner and outer plug grooves 258, 259 have the same depth D ₃ . In some embodiments, inner and outer plug grooves 258, 259 have different depths D ₃ relative to one another. Inner and outer grooves 258, 259 maximize the flexibility of plug wall 254 to allow engagement with container necks of varying inner diameters. Depth D ₃ can be adjusted to adjust an overall length of plug wall 254. Torque applied to plug wall 254 increases as depth D ₃ increases, thereby minimizing vertical installation force applied by a user to closure cap 214.

[0040] In the illustrative embodiment, at least a portion of plug wall 254 is disposed at an angle 259 relative to an axis A ₄ (parallel to installation axis A ₃ ) as shown in Fig. 15. Angle 259 allows plug wall 254 to engage with container necks of varying inner diameters. In some embodiments, angle 259 is about 50 degrees to about 80 degrees. In some embodiments, angle 259 is about 50 degrees to about 70 degrees.
