Abstract: A tamper-indicating closure that includes a base wall having a cylindrical skirt for removably engaging a container finish. A tamper band is frangibly connected to the skirt, and a plurality of wings extend inwardly from an inner surface of the tamper band for engagement with a container finish. The wings are resiliently flexibly connected to the inner surface of the band along lines that are disposed at a counterclockwise angle with respect to the axis of the skirt as viewed from inside the skirt.

Abstract: A child-resistant package includes a container having a finish with an open end, at least one external thread, at least one stop lug projecting radially outwardly from the finish, and a closure having a base wall, a skirt with at least one internal thread for engagement with the thread on the container finish, at least one spring element and at least one pair of internal lugs on the skirt and extending radially inwardly from the skirt. Each pair of lugs on the skirt includes a first lug that cooperates with the stop lug on the container finish to prevent unthreading of the closure from the finish absent pressure on the closure against the spring element to push the first lug on the skirt beneath the corresponding stop lug on the container finish, and a second lug circumferentially spaced from the first lug that cooperates with the stop lug on the container finish to prevent “over-threading” or over tightening of the closure on the finish.

Abstract: A plastic closure includes a plastic closure shell having a base wall with a central opening and a skirt with at least one internal thread or bead for securing the closure to a container finish. A plastic disk is retained within the shell parallel to but spaced from the base wall. The disk includes a plurality of axially extending spacer elements around the disk to engage the undersurface of the base wall and space the disk from the base wall of the shell, and angularly spaced fingers extending from the disk through the central opening of the base wall to retain the disk within the shell. A resilient liner is disposed on an underside of the disk for sealing engagement with the container finish.
