ABSTRACT:
A cap, which in addition to serving to removably seal a container, also acts as a carrier for torque-applying means that permit the cap to be released from a stuck position. The cap of the present invention is particularly well adapted for use on containers holding a lacquer based fingernail polish, although not restricted to such use. Caps on containers holding a lacquer base fingernail polish are notorious for tending to remain in a stuck position thereon, and to such an extent that pliers must be used to grip the cap and initially rotate the latter relative to the container on which it is mounted.
