Abstract: A valve assembly has a valve housing and a valve core body movable therewithin for providing a smooth and continuous outflow of liquid from a container, which may be unvented and rigid, through a liquid-out passageway, and provides an air-back passageway for drawing external air into the container. In a preferred embodiment, the core is rotatable within the housing by one-handed actuation. The air-back passageway is preferably a channel provided on the surface of the core body, and the liquid-out passageway is preferably provided between openings in the core body.

Abstract: A tamper indicating container and container-closure package in which the tamper indicating band is integrally molded on the container neck with connecting frangible webs. The tamper indicating band has circumferentially spaced pawls on its top which co-act with a circumferential array of ratchet teeth at the lower end of the closure cap skirt to prevent removal of the cap upon application of opening torque without fracture of the frangible webs indicating tampering or initial opening. The closure of the container-closure package includes a cap skirt having a wall portion which recesses the cap ratchet teeth and overlaps the tamper indicating band of the container so as to keep the ratchet locking mechanism out of the view of a person endeavoring to tamper with the package.

Abstract: A tamper indicating package in which the tamper indicating element is located on the container neck. A satellite ring is integrally molded with the container neck being connected thereto by a frangible connection between the ring and an integrally molded container neck flange. The frangible connection is broken to remove the closure from the container neck. Standard caps can be used on the container.
