    Abstract: A package comprising an outer carton housing a plurality of display packs, such as blister packs, each comprising an essentially planar support card. The carton is formed as a sleeve open at both ends and the packs are disposed in spaced parallel relation within the sleeve, and transversely to its side walls, and are held in desired positions within the sleeve by engagement with their respective support cards of flaps integral with the carton and turned inwardly, the flaps having free edges parallel with the support cards. Thereby obviating the need for separate spacers inside the carton.
