Abstract

A tamper evident closure employs a frangible tamper evident finger for initially retaining a lid in a closed position relative to a closure body. In response to an initial opening of the lid, the finger is separated from the lid and retained in a volume at least partly defined by the closure body. As the finger is connected to the lid by a frangible bridge in a confirmation window, upon separation of the finger from the lid, the now open confirmation window provides immediate and ready indication that the lid has been opened.
