Abstract

The method utilizes a carton for a group of capped bottles each having a sloping upper neck and a cylindrical lower portion. The carton is formed from a single molded blank. It includes a rectangular top panel having an inner area slightly less than the composite area of the grouped bottles across their caps. Sloping side and end walls lead downwardly from the top panel to engage shoulders of the bottles at intermediate locations along their height. The carton area across this intermediate plane is slightly less than the composite area of the lower portions of the grouped bottles. As the carton is applied over the grouped bottles, the lower ends of the bottles are initially spread because of the restricted area within which the caps are confined at the top of the carton. As the carton is wrapped about the lower portions of the bottles, they are pressed tightly toward one another and returned to parallel upright positions. The carton material is yieldable or compressible to assure production of a tight package without the need for interior partitions.
