A safety closure for a medicine bottle or the like. The closure and bottle neck have cooperating lug and ramp means of the bayonet type. The closure is placed over the bottle neck, depressed onto the neck and rotated relative to the neck to engage the lugs and ramps. To remove the closure, it is pressed downwardly to disengage the lugs and then rotated in the opposite direction. The closure is biased upwardly relative to the bottle neck by the engagement of an annular conical shoulder on the closure with upwardly turned fingers on a disc-like biasing element that is positioned between the top of the closure and the end of the bottle neck.
