Patent ID: 7235207

Claim:
A method of making a tamper-indicating closure that comprises the step of: integrally molding a closure of plastic as-molded construction that includes a base wall having a peripheral skirt with an at least one internal thread for affixing the closure to a container, a tamper-indicating band connected to an edge of said skirt, a stop element extending from said band, and a plurality of circumferentially spaced drain openings extending axially through said stop element, wherein said step of molding said closure is such that: (a) a plurality of circumferentially spaced channels are formed extending axially through said thread, at least some of said channels being axially aligned with said drain openings, (b) said drain openings are uniformly circumferentially spaced around said closure, and said channels are non-uniformly circumferentially spaced around said closure, and (c) said thread has a lead-in adjacent to said base wall, and said channels are at lesser circumferential spacing from each other at said lead-in than spaced from said lead-in.
