Abstract
A sealed container stores therein liquid such as eye drops in a sealed state. For dispensing the liquid first time, the factory-sealed outlet of the liquid is to be unsealed with a needled of a liquid discharge plug fitted within a cap in association with a user's operation of the cap in a loosening or tightening direction when the liquid is first dispensed therefrom. The container includes a one-way rotation preventing mechanism provided respectively at mutually opposing portions of a liquid discharge plug prefitted with the cap and the container. This mechanism prevents rotation of the liquid discharge plug in the loosening direction of the cap while allowing rotation thereof in the screwing direction of the cap when the cap has been tightened to a predetermined screwing position immediately before the needle initiates it penetrating action into the sealed liquid outlet. Also, a cam mechanism is provided respectively at mutually opposed positions of the discharge plug and the cap for pushing the liquid discharge plug toward the liquid outlet of the container body to a predetermined screwing position in association with the loosening operation of the cap under the rotation-restricted state provided by the one-way rotation preventing mechanism.
