MOLDED PLASTIC HOT-FILL CONTAINER AND METHOD OF MANUFACTURE

摘要

A blow molded plastic hot-fill container (10) includes at least one vacuum panel (30) for inward flexure under vacuum after the container is hot-filled and capped. The vacuum panel (30) is externally concave as viewed in cross section from a first direction and externally convex as viewed in cross section from a second direction orthogonal to the first direction. The at least one vacuum panel (30) preferably is disposed in a sidewall of the container (10), which preferably is of generally uniform wall thickness, and preferably includes an array of vacuum panels angularly spaced around an axis of the container.
