Abstract
A safety screw cap is made up of an inner cap arranged to be screwed onto the neck of a bottle and an outer cap forming a cover over the inner cap. A cam is formed on one of the end closing walls of the inner cap or the outer cap spacing them apart in the assembled position. Perforations are formed in the end closure wall of the outer cap providing it with flexibility so that it can be forced axially toward the inner cap whereby the screw cap assembly can be removed from the closed or sealed condition. Because of the cam extending between the end closure walls, when axial force is exerted on the outer cap the end closure wall of that cap assumes an arched configuration as the screw cap assembly is removed.
