Abstract
A closure comprising a main portion and a flip-top portion are provided. The main portion comprises a tab and at least one rib. The flip-top portion is operatively connected to the main portion and is movable with respect to the main portion. The tab can be configured to break at least partially away from the at least one rib as a result of downward force applied to the tab. The at least one rib can be configured to spiral partially away from the tab and the main portion when the tab is pulled in an upward direction away from the main portion. The tab and the at least one rib comprise a tamper evident seal.
