发明名称 Tamper-indicating package and plastic closure therefore
摘要 A tamper-indicating package that includes a blown glass container or blow molded plastic container, and a molded thermoplastic closure that is affixed to the finish portion of such container. The finish portion of the container has a radially outwardly projecting bead at the bottom portion of such finish portion. The closure has a flexible tab that originally extends outwardly and downwardly from the top of a notch in the skirt of the closure, and is foldable through the notch in the skirt of the closure to engage the underside of the bead in the finish of the container. The closure tab is attached to the closure skirt by a frangible connection, and separates from the closure skirt by the fracture of such frangible portion during the removal of the closure from the container, since the tab is prevented by its engagement with the container bead from being removed with the other elements of the closure.
