Abstract: A closure includes first and second closure portions. The first closure portion includes a polymeric top wall portion and an annular skirt portion. The skirt portion includes exterior and interior surfaces. The interior surface includes an internal thread formation for mating engagement with an external thread formation of a container and at least one rotation-inhibiting projection. The rotation-inhibiting projection is located to contact the external thread formation. The rotation-inhibiting projection is in the general shape of the letter “C” prior to engagement with the external thread formation of the container. The second closure portion includes a polymeric tamper-evident band.

Abstract: 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.

Abstract: A tamper-indicating plastic closure, and tamper-evident package includes a closure 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. The tamper-ring includes a plurality of circumferentially spaced projections, which comprise relatively thick regions or shoulders, which 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.

Abstract: A capping and nitrogen dosing apparatus for containers includes a rotary capping machine which is configured to serially receive filled containers, and apply closures to respective ones of the containers. The present apparatus includes a dosing system for injecting an inert gas, typically nitrogen in liquid form, into the head space of each container to enhance the integrity and rigidity of the package, and to improve the freshness and flavor of the container's contents. Notably, the dosing system is configured to effect nitrogen injection close to or at the so-called transfer point of the capping machine, thus desirably abating nitrogen dissipation, and enhancing consistent and efficient product dosing.
