  • Patent number: 4629081
    Abstract: This invention comprises a two part closure, for a container, comprising a top cap hingedly connected to an inner cap which is adapted to be semi-permanently positioned over the mouth of an associated container, a depending skirt on the inner cap and a trigger forming part of the skirt of the inner cap, actuation of the trigger normally being prevented by engagement of the trigger with an arcuate bead on the outside of the associated container whereby the trigger forms a locking means to hold the top cap in its closed position until the closure is angularly displaced relatively to the container into a predetermined position in which the trigger is unlocked and can be actuated manually to release the top cap for opening.
