Abstract
This invention provides a container and closure assembly. The closure consists of a plug which fits into the mouth of the container in such a position that removal of the closure is prevented until the closure is turned to bring a recessed thumb grip on the side of the closure into registration with a gap in the container wall. When the closure is in this position the closure can be pushed out of the container by passing the thumb of the user through the gap.
