HOT-FILL CONTAINER HAVING FLAT PANELS

摘要

A container may employ an upper portion defining a mouth, a shoulder portion formed with the upper portion and extending away from the upper portion, a bottom portion forming a base, a sidewall extending between and joining the shoulder portion and the bottom portion, and a plurality of smooth surfaced vacuum panels formed in the sidewall, which may be separated by one or more strengthening grooves. The vacuum panels and/or the container in a profile view may form an hourglass shape. The container may also employ a sidewall utilizing three smooth, grooveless, vacuum panels, which may form a triangle in cross-section. The vacuum panels may be concave inward toward a central vertical axis of the container and have an hourglass shape when the container is viewed in a side view.
