A tamper-indicating closure is used with an associated container having a finish including an external thread formation thereon, and an annular locking ring located axially under the thread formation. The closure includes a closure cap having a circular top wall portion and an annular skirt portion depending from the top wall portion. An internal thread is formed in the skirt and defines a skirt wall plane. The closure includes an annular tamper-indicating band depending from the cap that is detachably connected to the cap by a plurality of circumferentially spaced, tapered, frangible connectors extending between the band and the cap. The connectors taper to define a region adjacent to a juncture of the connector and the band having a cross-section that is smaller than a cross-section at a region of the connector adjacent to a juncture of the connector and the closure cap.

[ What is claimed is:] [1.] A tamper-indicating closure for use with an associated container, the container having a finish with an external thread formation thereon and including an annular locking ring located axially under the thread formation, the closure comprising:a closure cap having a circular top wall portion and an annular skirt portion depending from said top wall portion, said skirt portion having an internal thread formed therein threadedly engageable with the container thread formation; anda continuous annular tamper-indicating band depending from said cap and being detachably connected to said cap by a plurality of circumferentially spaced, frangible connectors, said band having a substantially constant radial cross-section along its circumferential length, and including an internal surface engageable with said locking ring for separating said band from said closure cap, each of said connectors defining a region adjacent to a juncture of said each connector and said band having a first cross-section that is smaller than a second cross-section at a region of said each connector adjacent to a juncture of said each connector and said closure cap, said connectors tapering in a radial direction having a cross-section decreasing with an increase in distance from a longitudinal axis of said cap such that a chord on an inner surface of each of said connectors is longer than a chord on an outer surface of each of said connectors, each said connector defining a substantially trapezoidal cross-section when said cross-section is taken in an axial direction.
