Abstract

A cardboard package is disclosed which comprises two subsidiary boxes (10, 11) which are initially joined to one another at a central fold line. The subsidiary boxes can be separated in the region of a central folding edge (14) at the central fold line because of weaknesses in the material (e.g. perforations), so that two self-contained subsidiary boxes, enclosed on all sides, are formed. The package is formed from a single blank. The blank is of a uniform width throughout--with the exception of the lid (29, 30). Pairs of side flaps (32, 33, 34, 35) are positioned on opposed sides of the blank to form the side walls (23, 24, 25, 26), with the side flaps in the assembled package being positioned in one plane without overlap and are held together by base flaps (36, 37).
