Tamper-indicating closure and container with drain elements and methods of manufacture

摘要

A tamper-indicating closure (22) for a beverage package includes a base wall (28) having a peripheral skirt (30) with at least one internal thread (32) for securing the closure to a container. A tamper-indicating band (34) is frangibly connected to an edge of the skirt, and a stop flange (38) extends axially and radially from an edge of the band for abutment with a stop bead on the container finish. A plurality of circumferentially spaced drain openings (56a to 56h) extend axially through the juncture of the band and the flange. A plurality of circumferentially spaced channels (54a to 54h) extend axially through the internal thread on the closure skirt, with at least some of the channels being axially aligned with the drain openings. The stop bead on the container may be in the form of a plurality of circumferentially spaced bead segments (48a to 48j) separated from each other by circumferential gaps (58a to 58j). Liquid product may readily drain from between the container finish and the closure skirt through the axial channels in the closure thread, through the drain openings at the juncture of the closure flange and band, and through the gaps between the stop bead segments on the container finish. The container finish may also have a support flange (82 or 94) with drain channels (82a to 82j) or slots (94a to 94c) aligned with the gaps in the bead. <IMAGE> <IMAGE>
