Abstract

A glass container in the form of a growler is provided with a re-sealable roll-on closure. An improved construction is provided for the container enabling it to handle higher pressures in which minimum glass wall thicknesses are optimized to provide necessary strength for the container, yet the construction conserves amounts of glass used. In a preferred embodiment, the container is capable of holding a 64 oz beverage, and the container includes a re-sealable roll-on 38 mm closure with a capacity to hold up to 3.00 v/v CO₂ pressure at 145° F. A minimum glass wall thickness along a sidewall of the container starting from a mid-neck down to a heel portion of the container is 2.5 mm. An integral glass handle is provided with a minimum break strength of 170 pounds. In a preferred embodiment, the container has a maximum to minimum sidewall thickness ratio of approximately 2:1 and a base thickness ratio of approximately 1.5:1.
