Abstract
Abstract The present invention is directed to a child resistance container and lid which utilizes a semi-flexible ring. The snap lid which is utilized in the present invention container is substantially set into the top of the container and this lid has one component of either an extended lift member or an indented lift guide. The ring has the other component of either the extended lift member or the indented lift guide. When the ring is rotated, the snap lid cannot be opened. The snap lid can only be opened when the ring is simultaneously squeezed and rotated. In an alternative embodiment, the two component lift system is utilized wherein both components extend outwardly rather than one extending outwardly and one indented. They have geometric configurations so that one first slides past the other and then, in their reverse motion, one lifts the other so as to lift up a lid during operation.
