Abstract
Abstract A container and a safety closure therefore wherein the container and closure have portions that are interengageable when the closure is mounted on the container neck to make the closure difficult particularly for children to remove and flush fitting flap integral with the closure and resting in a recess in the top of the closure and on a partition at the bottom of the recess which is provided with at least one dispensing opening. The flap has an integral nosed plug or bung to seal the opening in flush flap position, the nose making it difficult to open. The flap may be swung from its flush position on the closure to an open position by the proper user to withdraw the plug or permit the closure to be removed from the container, the dimensions of the closure and the normally flush position of said flap also making it very difficult if not impossible for children to lift the flap of the closure from its flush position, thus providing safe storage for dangerous container contents and preventing unauthorized access thereto.
