Abstract
A glass container includes a sidewall circumscribing a central longitudinal axis, and including a neck finish, which includes a wall having a radially inner surface and a radially outer surface and a rim extending from the wall. The rim has a sealing lip, an outward lip, and a retention lip extending between the outward lip and the radially outer surface of the wall. A ratio of a radial thickness of the rim at a major outer diameter of the outward lip of the rim to a radial thickness of the neck finish wall below the rim and between the radially inner and outer surfaces is between 1.9:1 and 2.2:1. A package includes the glass container and a ring pull cap closure coupled to the rim.
