Abstract
An injection molded plastic closure having a tamper indicating portion. The tamper indicating portion includes a tampering indicating band which is attached to the skirt for radially outward hinging by a plurality of bridges. The tamper indicating band is subject to splitting whereby it may expand outwardly and clear a container neck finish. The tamper indicating band remains attached to the closure and the splitting thereof indicates tampering. Bridges attaching the tamper indicating band to the closure skirt are of sufficient cross section to have the required structural strength to prevent separation of the tamper indicating band from the closure skirt and at the same time permit injected molten plastic to freely flow from the closure skirt into the tamper indicating band. The tamper indicating band carries a plurality of locking flaps which are attached thereto by hinges which are defined by external areas of weakness which are shaped to be defined by a mold member which does not interlock with the closure and provides for ease of stripping.
