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.

Tamper-indicating closure and package

A plastic closure includes a plastic closure shell having a base wall with a central opening and a skirt for securing the closure to a container neck finish. A plastic disk includes angularly spaced fingers extending into the central opening of the shell base wall and external beads on the fingers for engaging an inner periphery of the central opening to retain the disk within the shell. The beads have flat undersurfaces and the inner periphery of the central opening has a ledge with a conical surface engaged by the beads. Any doming that occurs in the disk and/or the closure shell base wall increases the surface contact between the finger beads and the opposing surface of the ledge so that removal of the shell from a container neck finish will simultaneously lift and remove the disk from the neck finish without having the beads snap through the central opening in the shell so that the shell is removed while the disk is retained on the neck finish.

Closure and package for high-temperature applications

A child-resistant package includes a container having a finish with an open end, external thread, stop lug projecting radially outwardly from the finish, and a closure having a base wall, a skirt with internal thread for engagement with the thread on the container finish, spring element and pair of internal lugs on the skirt and extending radially inwardly from the skirt. Each pair of internal lugs 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 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 to prevent over tightening of the closure on the finish.

Child-resistant closure, container and package

A plastic closure includes a plastic closure shell having a base wall with a central opening, a skirt for securing the closure to a container neck finish, and an internal ledge on the skirt adjacent to but spaced from the base wall. A plastic disk is retained within the closure shell. The disk includes a plurality of axially extending spacer elements, preferably in the form of angularly spaced circumferentially aligned bead segments around a peripheral portion of the disk, to engage an underside of the base wall and space the disk from the base wall of the shell. Angular gaps between the spacer elements permit flow of fluid from the central opening, between the base wall and the disk and through the gaps. A periphery of the disk is disposed between the internal ledge on the skirt and the base wall of the shell to capture the disk such that the disk is free to rotate within the shell. A resilient sealing liner is molded onto an underside of the disk for sealing engagement with the container neck finish. The internal ledge on the skirt preferably includes at least one radially inwardly opening axially extending drain slot to permit flow of fluid around the periphery of the disk and through the slot in the ledge.

Tamper-evident closure having a sealing disk and package for high-temperature applications

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.

Plastic closure, closure and container package, and method of manufacture

Squeeze-and-turn child resistant closure

A package for tablet products that includes a container having an interior volume for holding the tablet products and a closure secured to a cylindrical finish of the container. A product hold-down device has an axially resilient central portion, a lower portion for engaging the upper surface of the product within the container, and an upper portion for securement within the container finish to hold the device in place within the finish, with the closure removed from the finish, against the axially resilient forces applied to the device by engagement of the lower portion with product in the container and resilient compression of the central portion of the device. Thus, the hold-down device can be inserted into the container and secured to the container using automatic packaging equipment, and the container closure then applied to the container. In use, the closure is removed from the container, and the device is removed and discarded by the user.
