Mass reduction of plastic bottles containing non‐carbonated liquids calls for advanced design approaches. Weight reduction of bottles consequently influences the mechanical performance of the bottle. This performance involves top load, vacuum and impact resistance. The present paper studies the lateral deformation of a bottle due to an internal vacuum. Similar studies have been carried out before, but until now the allowable deformation has never been related to the initial headspace of the bottle. If a bottle design is able to compensate for a potential vacuum in an aesthetic manner, then panelling will not occur. Changing the vacuum resistance of a bottle will result in a different top load. Current computational techniques enhance our understanding of the problem and provide tools to achieve solutions to it. © 1998 John Wiley & Sons, Ltd.
