An improved light weight liquid-containing stackable bottle made of plastic such as polycarbonate. The bottle is preferably of rectangular cross-section with parallel oppositely disposed mating sides which permits secure and space-saving stacking of the bottles. Complementary projections and receptacles are formed in the mating sides of the bottle to permit interlocking of the bottles when they are stacked. Desirably, vertical and horizontal corrugation are formed in the sides of the bottle to provide strength and reinforcement against both sideways and axial forces. The non-parallel corrugations preferably do not intersect to avoid the creation of stress points which could lead to cracking and flaws in the bottles. Horizontal corrugations are remote from the bottom and shoulder parts of the bottle in order to improve impact resistance.
