A tamper-indicating container-closure package assembly is composed of a container including a base, a sidewall portion extending upward from the base, and a finish portion connected to an upper region of the sidewall portion defining a mouth of the container. The finish portion includes a threaded portion located inside the mouth which can include at least one interruption for allowing venting of the container as a closure is removed. A seal seat is recessed inside the mouth, yet is situated above the threaded portion, while a radially outwardly bulbous portion protrudes outside of the mouth. The closure includes a threaded cylindrical surface dimensioned to cooperatively engage the threaded portion of the container finish, a top portion radially outwardly extending from the threaded cylindrical surface including a seal portion which depends downwardly from the closure top portion for engagement with the seal seat, and a tamper-evident ring portion depending downwardly from an outer periphery of the top portion of to engage the radially outwardly protruding bulbous portion outside the container mouth. A container support ring is situated below and extending radially outward at least to a point coextensive with a radially outermost surface of the tamper-evident ring portion of the closure. The seal seat can include an annular groove with a plurality of venting grooves extending radially on either side of the seal seat.
