ABSTRACT:
A container includes a closure having a neck with a break-away ring. A cap which covers the neck has a depending edge with a barb-like tip which is received in the space between the break-away ring and the neck of the container. During an initial opening operation, sloped surfaces on the cap and break-away ring engage to force the break-away ring outwardly to remove it from the neck. This provides both tamper and child-proof features. After the initial opening operation, the cap may be secured to the neck by a separate connection.
