Child-resistant cap

Abstract

A multiple-piece cap assembly which is child-resistant, yet which, because of radial contact between the caps, can be more easily opened by persons such as the elderly, arthritic, disabled and infirm adults. In an exemplary embodiment of the present invention, removal of the cap assembly requires two simultaneous motions such as, for example, turning the cap and pushing downward to engage lug and ramp projections on the caps. In this embodiment of the present invention, the two caps engage each other by a ramp and lug configuration in order to fasten and remove the cap assembly, wherein the lugs and ramps engage one another substantially by “line” contact and/or “surface-to-surface” contact. The cap of the present invention thus requires less force in at least one direction of the concurrent motions in order to remove the cap assembly, thus making the cap assembly child-resistant, yet senior-friendly.
