Abstract

Abstract A combination container and safety locking closure for chemicals that are dangerous such as bleaches and the like. The closure has a closure portion that is screwed onto the externally threaded neck of a container and fits snugly on the upper part of the container. There is a skirt which flares from the closure part, said skirt having oppositely arranged inwardly opening recesses adapted to be received in lugs provided therefor on the container. The material of the container is flexible and resilient, such as a plastic (Polyethylene) when the lugs are in the recesses, the closure device is locked on the container. In order to release the closure, the sides of the container below the lugs and below the free edge of the skirt are squeezed or pressed inwardly so that the lugs are forced out of the recesses of the skirt, where upon, the closure device may be unscrewed. With the closure device removed, it may be turned with the open end of the skirt turned upwardly and used as a measuring cup.
