ABSTRACT:
A threaded safety dispensing closure and container package in which the initial threading on of the closure to the product filled container affixes the closure to the container so that it cannot be removed, requiring dispensing through the dispensing orifice in the closure top and inhibiting refilling of the container. The container neck terminates in an annular end wall having a plurality of circumferentially spaced ratchet teeth which coact with the top of the closure cap allowing threading on but locking the cap to the container against unthreading removal. Tamper indication can be provided by an integrally molded insert across the dispensing orifice which is removed by a pull tab.
