ABSTRACT:
A tamper-indicating plastic closure includes a top wall portion, a depending annular skirt portion, and a container-engaging pilfer band at least partially detachably connected to the skirt portion. In order to avoid premature fracture of the connection between the pilfer band and the closure skirt, a selectively strengthened frangible connection is provided, preferably comprising a series of first relatively weak bridges, and a series of second relatively strong bridges. The relatively strong bridges are provided about a major portion of the circumference of the pilfer band and are sufficiently strong to resist premature fracture. The minor portion of the circumference at which the first relatively weak bridges are provided fractures and separates first during closure removal, permitting the pilfer band to engage the container to create a high resistance to removal for thereafter sequentially fracturing the second bridges.
