Abstract:
In combination: (a) an outlet for a container comprising: an externally-threaded sidewall defining a dispensing opening, said sidewall having a base portion; an outer annular skirt positioned at the base portion of said sidewall; anda pair of circumferentially spaced-apart abutment projections integrally formed as part of said outer annular skirt, each abutment projection including an abutment surface; and (b) a closure cap constructed and arranged for threaded assembly onto said outlet for closing said dispensing opening, said closure cap comprising: an internally-threaded outer wall defining a hollow interior; a top surface for closing one end of said hollow interior; and a pair of circumferentially spaced-apart abutment ribs integrally formed as part of said outer wall, each abutment rib including a free end and being constructed and arranged for riding over each abutment projection during the threaded advance of the closure cap onto the outlet and for abutting engagement against a corresponding one of said abutment projections during retrograde rotation of said closure cap from said outlet, each of said pair of abutment ribs being manually movable in a radially inward direction for taking the corresponding abutment rib out of abutting engagement, wherein the circumferential spacing between said pair of abutment ribs in a clockwise direction is different from the circumferential spacing in a counterclockwise direction.
