Abstract A closure for bottles, cans and like containers which is difficult for small children to open comprises a stationary member adapted to be mounted upon the neck of the container, said member having a dispensing aperture communicating with the passage through the container neck, and comprising a locking ring mounted on and rotatable with respect to said stationary member. Said stationary member includes a hinged lid provided with a stopper adapted to close and seal said dispensing aperture when the lid is closed. Said lid is normally locked in closed position by said locking ring. To open the container the locking ring must be rotated to a position to release the lid which can then be lifted to remove the stopper from the dispensing aperture. Rotation of the locking member to release the lid stresses one or more springs carried by said locking ring so that after the lid is opened, the locking ring is returned to its original locking position by the springs. When the lid is closed cooperating cam surfaces on the lid and locking ring rotate the locking ring to again stress the springs, which thereafter automatically return the locking ring to locking position to again lock the lid in closed position.
A closure for containers comprising a stationary member adapted to engage the neck of a container, said stationary member having a dispensing aperture communicating with the passage through the container neck, and having a hinged lid connected thereto provided with a stopper adapted to close and seal said dispensing aperture when the lid is closed, and a locking ring rotatably mounted on and surrounding the periphery of said stationary member, said locking ring and stationary member having means including interengaging flange elements to engage and lock said lid in closed position in one position of rotation of said locking ring and to release said lid in another position of rotation, a spring comprising a flexible, resilient prong carried by said locking ring and extending radially inwardly from said ring over said stationary member, and a stop on said stationary member which engages and stresses said spring on rotation of said locking ring to release said lid.
