  • Publication number: 20060118508
    Abstract: An improved hot-fill type container that has particular utility for use with the nitrogen dosing hot-fill process includes a finish portion, a main body portion and a base portion having a pushup area and a chime that is situated about the pushup area for supporting the container when a horizontal surface. The container advantageously includes a reinforced heel portion in the area between the main body portion and the chime for protecting the container against deformation that could otherwise be caused by the positive pressurization of the nitrogen dosing process. The heel portion is generally convex and is formed of at least two radiused areas, with a lower radiused area having a smaller radius than an upper radiused area. In addition, a lower region of the heel portion preferably is reinforced with an increased sidewall thickness with respect to the average sidewall thickness of the main body portion and upper regions of the heel portion. A method of making such containers is also disclosed.

  • Publication number: 20040000127
    Abstract: A method of filling a container, and thereby extending the effective life of an oxygen scavenger, includes providing a container having an oxygen scavenger material, introducing product contents and a liquefied gas into the container to displace at least a portion of the air within the headspace, and capping or otherwise sealing the container. Displacing oxygen from the headspace diminishes the available oxygen within the container that can permeate into the container sidewall, thereby extending the effective life of the scavenger.
