Abstract:
A closure, comprising:a closure cap including a top wall portion, and a cylindrical skirt portion depending from said top wall portion,said cylindrical skirt portion including an internal thread formation extending circumferentially of said closure at least 360.degree., said thread formation including a thread start at an end of said thread formation spaced furthest from said top wall portion, anda plurality of rotation-inhibiting projections provided on the inside surface of said skirt portion adjacent said thread formation for engagement with a mating thread formation on an associated container;a primary one of said rotation-inhibiting projections being spaced from said thread start between about 20.degree. and 40.degree. relative to the circumference of said closure, said primary projection being positioned in most closely spaced relation to said thread start, whereby said primary projection is the first one of said rotation-inhibiting projections to engage an associated container thread, said primary projection being asymmetrically configured relative to a radius of said closure through the primary projection;said closure including at least one secondary rotation-inhibiting projection positioned symmetrically with respect to a portion of said closure diametrically opposite of said primary projection, said secondary projection being spaced from said primary projection at least about 140.degree. circumferentially of said closure.
