    • A hot-fill container that has particular utility for use with the nitrogen dose 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 on a horizontal surface. The container includes a reinforced heel portion with 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 the upper radiused area. In addition, a lower region of the heel portion 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.
    • 具有用于氮剂量热灌装工艺特别实用的热灌装容器包括精加工部分,主体部分和具有上推区域和基座部分的基部,该基部围绕用于支撑容器的上推区域 在水平面上。 容器包括加强后跟部分,其中主体部分和钟子之间的区域用于保护容器免受另外可能由氮气加料过程的正加压引起的变形。 鞋跟部分通常是凸形的,并且由至少两个圆角区域形成,其下半径区域具有比上部圆角区域小的半径。 此外,跟部的下部区域相对于主体部分的平均侧壁厚度和跟部的上部区域的侧壁厚度增加而被增强。
