A composite container (10) comprising a rectangular cuboidal rigid outer-container (20) comprising a top and a bottom surface (21,22) connected by four side walls (23), and a single compressible, rigid inner-container (30) for containing a pourable product, said inner-container having a basis weight
A composite container (10) comprising a rectangular cuboidal rigid outer-container (20) comprising a top and a bottom surface (21,22) connected by four side walls (23), and a single compressible, rigid inner-container (30) for containing a pourable product, said inner-container having a basis weight of from 150 g/m2 to 700 g/m2, and said inner container comprising a top (31), a bottom (32), and a closable opening (33) located at said top. The inner-container (30) comprises at least one zone (34) having a circular cross-section and at least two zones (35) having a non-circular cross-section, whereby said at least two zones (35) having a non-circular cross-section are in contact with the inner surface of said outer-container (20). The at least two zones (35) having a non-circular cross-section are separated by said at least one zone (34) having a circular cross-section.
