A carton for a group of capped bottles having sloping upper necks and cylindrical lower portions. 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 in a horizontal plane. The carton area across this intermediate plane is slightly less than the composite area of the lower portions of the grouped bottles. The carton is applied over the grouped bottles, initially spreading the lower bottle ends because of the restricted area within which the caps are confined. As the carton is closed, the lower bottle portions are pressed slightly toward one another. The yieldability of the carton material at its corner area assures production of a tight package without interior partitions for safe shipping of bottles.
