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 tablet dispensing container comprehending a tubular sleeve, a reciprocating element and a locking mechanism. The tubular sleeve forms the container and has two opposing openings therein; a dispensing opening in the lower end and a reciprocating element opening in the upper end. The reciprocating element is attached to the tubular sleeve and is biased toward the upper end. A user manually depresses the reciprocating element which forces the end with the tablet accommodating mechanism through the dispensing opening thereby dispensing a tablet. A locking mechanism prevents the reciprocating element from reciprocating when in a locked position. The locking mechanism permits reciprocation of the reciprocating element when in the unlocked position. The locking mechanism is adapted to remain in either the locked or the unlocked position until manually moved to the other position. Preferably, the locking mechanism includes a visual signal which indicates when the locking mechanism is in the unlocked position.
