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.
Claims20
A glass container, comprising:
- a base;
- and
- a sidewall extending away from the base, circumscribing a central longitudinal axis, and including a beaded neck finish terminating the side wall, wherein the beaded neck finish includes:
- a wall having a radially inner surface and a radially outer surface;
- a rim extending from the wall and terminating the beaded neck finish and having:
- a sealing lip facing axially outwardly and extending substantially perpendicular to the central longitudinal axis,
- an outward lip facing radially and axially outwardly,
- a retention lip facing axially inwardly and radially outwardly and extending between the outward lip and the radially outer surface of the wall,
- a first rounded surface extending between the sealing lip and the outward lip, and
- a second rounded surface extending between the outward lip and the retention lip;
- and
- a filleted surface extending between the retention lip and the radially outer surface of the wall,
- wherein 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 wall of the beaded neck finish below the rim and between the radially inner and outer surfaces is between 1.9:1 and 2.2:1.
