摘要:
A tamper-indicating plastic closure, and tamper-evident package are disclosed, wherein the closure includes a pilfer band having a substantially continuous tamper-ring. The tamper-ring extends generally angularly upwardly and inwardly of the closure in a tamper-indicating orientation of the tamper-ring for engagement with a relatively enlarged annular locking ring of the associated container. Notably, the tamper-ring includes a plurality of circumferentially spaced, projections, which preferably comprise relatively thick regions or shoulders, which desirably act to limit lateral movement of the pilfer band with respect to the container by engagement of at least one shoulder with the associated container generally beneath the container locking ring.
摘要:
A plastic closure embodying the principles of the present invention comprises a closure cap having a top wall portion, and an annular skirt portion depending from the top wall portion. The skirt portion includes an internal thread formation for threaded engagement with the external thread formation of an associated container. In order to facilitate high-speed application, and minimize the use of polymeric material, the closure is configured to exhibit a variation in retention force which decreases in a direction away from the top wall portion of the closure cap.
