Abstract:
A container closure includes an inner core having a non-cylindrical profile created by a variable longitudinal cross-sectional area. One or more outer layers concentrically surround the core and have a cross-sectional area inversely correlated to the inner core so that the overall container closure has an essentially cylindrical profile.
