Abstract
A child-resistant safety cap for a container for liquids such as strong cleaners has an inner cap and an outer cap selectively engagable by teeth on the caps requiring axial pressure on the outer cap to engage and threadably loosen the inner cap from a neck of the container. The inner cap includes a protruding plug member that extends into a free end of a nozzle on the container, spaced from the threaded part of the container neck. Cylindrical inner surfaces of the outer cap conform to outer surfaces of the inner cap, the inner and outer caps remaining closely aligned with respect to the container neck. Complementary structure between the inner cap and the nozzle engage when the inner cap is fully tightened. The safety cap closes a container having an S-shaped bend accumulating a charge of liquid in a trap in the bend, the nozzle having a rearward conduit part reaching into the trap. The inner and outer caps engage by engagement teeth on one of the caps that engage perpendicular stops in the facing cap, the teeth having a surface sloped with respect to a radial plane in a cap-loosening direction, and a perpendicular abutment in a cap-tightening direction. Preferably, the sloping plane is oriented at about 50 degrees to the radial plane.
