ABSTRACT:
The subject-matter of the invention is a foldable package, having a bottom part (1) and a top package part (2) which can be separated. These parts each have side walls (3, 4, 5, 6, 7, 8, 9, 10) which are linked to one another in series. Bottom flaps (15, 16, 17, 18) are linked to longitudinal edges of the bottom part (1). Connection flaps (21, 22) are linked to the longitudinal edges (19, 20), located opposite the side walls (3, 4, 7, 9) of the bottom part (1), of at least two bottom flaps (15, 17). The connection flaps releasably connect the bottom flaps (15, 17) to longitudinal edges of the side walls (5, 6) of the top package part (2). The package can be made from a single blank and erected so as to be ready for filling using a conventional erecting machine. To remove the top package part (2), the connections between the bottom flaps (15, 17) and the associated longitudinal edges of the side walls of the to package part (2) are released, and said top part (2) is pulled up out of the bottom part (1).
