Abstract: A container for use with a closure is provided, and includes a receptacle, a neck extending therefrom, a closure-engaging thread segment arranged on the neck of the container to engage the closure thread segment arranged on the closure, and a plurality of spaced apart protrusions protruding radially toward the closure from the neck of the container, the plurality of spaced apart protrusions forming a protrusion pattern that has a composite orientation that is helically opposite that of the closure-engaging thread segment to engage and to separate the frangible tamper-evident band portion from the closure when the closure is rotated off of the neck. With this structure, the closure and container system provides an improved anti-backoff, tamper evident closure and container system that reduces torque used to initially apply the closure to the container and improves reliably by reducing stress on the component parts, while desirably preventing backoff from occurring.

Abstract: A medicine container includes a child-resistant closure with a tamper-evident feature. The closure includes a plug adapted to be fixed to the container adjacent the open end. The plug has an access opening for enabling removal of material from the container through the open end of the container. A slide is supported on the plug for sliding movement in a first direction relative to the plug between a closed position in which the slide covers the access opening and an open position in which the access opening is uncovered. A child-resistant feature is interposed between the plug and the slide. The closure also includes a tamper-evident feature that permanently indicates breaking of the original seal of the container. The container may have a rectangular configuration including at least one surface large enough for a mailing address label; and a sealable window mailer envelope for receiving the medicine container.

Abstract: A tamper evident closure for containers having finish a with thread means and a radially outwardly circumferentially extending bead below the threads comprising, a cap portion of cup-like form having internal threads for cooperatively engaging the threads on a container to apply and remove the cap portion, a retainer ring depending from the lower edge of the skirt portion of the cap and connected thereto by a series of circumferentially spaced bridge connections, and a tamper evident band having means for rotatably mount on the retaining ring and rotatable thereto and including a series of spring fingers for engaging under the retainer bead on the container when the closure is fully seated.
