Abstract: A tamper-indicating closure for a beverage package includes a base wall having a peripheral skirt with at least one internal thread for securing the closure to a container. A tamper-indicating band is frangibly connected to an edge of the skirt, and a stop flange 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 extend axially through the juncture of the band and the flange. A plurality of circumferentially spaced channels 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 is in the form of a plurality of circumferentially spaced bead segments separated from each other by circumferential gaps.

Abstract: A tamper-indicating closure includes a plastic shell having a base wall with an annular skirt, at least one internal thread segment on the skirt, a tamper band frangibly connected to the skirt, and a circumferential array of angularly spaced flexible resilient ratchet wings extending counterclockwise from an inner surface of the tamper band at an angle to the inner surface. A flexible resilient sealing liner on the base wall within the skirt has a conical sealing surface that faces radially outwardly toward the skirt and axially away from the base wall. The conical sealing surface is resiliently engageable with a trim flange of a container to which the closure is applicable so that the tamper band separates from the annular skirt before loss of sealing engagement between the liner and the trim flange.

Abstract: A closure and container package that includes a container having a finish with an external thread, and a closure having a base wall and a peripheral skirt with an internal thread for threadably engaging the external thread on the container finish. An internal rib on the skirt extends axially of the skirt between overlapping reaches of the internal thread for frictional engagement with the external thread on the container finish to retard rotation of the closure onto and off of the finish. In the preferred embodiments of the invention, there are diametrically opposed ribs on the internal surface of the peripheral skirt extending between overlapping reaches of the internal thread, with the ribs being of lesser radial thickness than the internal threads. A tamper-indicating band is coupled to the lower edge of the peripheral skirt by frangible bridges for engagement with a bead on the container finish.

Abstract: A tamper-indicating closure of integrally molded plastic construction that includes a base wall having a peripheral skirt with an internal thread for affixing the closure to the container finish. A tamper-indicating band is connected to an edge of the skirt by frangible bridges. A stop flange extends from an edge of the band remote from the skirt for abutment with a bead on the container finish to inhibit removal of the closure absent fracture of the frangible means. A plurality of circumferentially spaced openings extend radially through the skirt at a position between the frangible bridges and the internal thread. These openings provide for ingress of cleansing solution during a washing operation after the closure is applied to a container to flush any residue from between the tamper-indicating band and the closure finish.

Abstract: A tamper-indicating closure of integrally molded plastic construction that includes a base wall having a peripheral skirt with internal threads for engaging external threads on the finish of a container. A tamper-indicating band is connected to the lower or free edge of the skirt by a plurality of circumferentially spaced integral bridges. At least one of the bridges has a greater circumferential dimension than other of the bridges. A thin integral membrane is disposed in the band immediately circumferentially adjacent to the one bridge, and extends both axially and circumferentially of the band. A stop flange is positioned on the band for engaging a bead on a container to inhibit removal of the closure, such that the membrane and the other bridges rupture upon removal of the closure but the band remains connected to the closure by the one bridge of enlarged circumferential dimension.

Abstract: A plastic closure and method of making such a closure for a container that has a finish with a top surface portion, a cylindrical outer surface portion, and a curved portion at the juncture of the top surface portion and the outer surface portion. The closure includes a base wall, a peripheral skirt having an inner surface and threads on the inner surface of the skirt for engaging the container.
