Abstract
Abstract 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.

Claim 8
Dependent Claim
26 words
A bottle according to claim 3 wherein the vertical side wall reinforcing corrugation and horizontal side wall reinforcing corrugation are constructed and arranged to not intersect.
Claim 9
Dependent Claim
41 words
A bottle according to claim 3 wherein said mating side wall faces are opposed side wall faces of the bottle, one mating side wall having horizontal side wall reinforcing corrugation and another mating side wall having vertical side wall reinforcing corrugation.
Claim 10
Dependent Claim
39 words
A bottle according to claim 7 wherein one mating side wall includes a plurality of mating projections and vertical side wall reinforcing corrugation and another mating side wall includes a complementary mating receptacle and horizontal side wall reinforcing corrugation.
Claim 11
Dependent Claim
18 words
A bottle according to claim 8 constructed and arranged to have no intersection of vertical and horizontal corrugations.
Claim 12
Dependent Claim
133 words
A bottle comprising a body defining a receptacle, said body having a rectangular cross-section and at least four side walls, a top, and a bottom, two of said side walls being opposed parallel mating side walls, one of said opposed parallel mating side walls having at least one mating projection and the other of said opposed parallel mating side walls having a complementary mating receptacle to permit stacking of two of said bottles on their mating side walls, said body also having horizontal reinforcing corrugation in at least a first side wall, and vertical reinforcing corrugation in a second side wall, the vertical reinforcing corrugation being non-aligned and non-intersecting with the horizontal reinforcing corrugation, and a corrugation-free side wall portion between said horizontal reinforcing corrugation and the bottom to absorb shock from droppage.
Claim 13
Dependent Claim
