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.
Claims19
A bottle comprising a body defining a receptacle, said body having two opposed mating side walls constructed and arranged to permit stacking and mating of two of said bottles when stacked with their opposed side walls mated, a top, a bottom, non-aligned reinforcing corrugation formed in two mating side walls, the reinforcing corrugation in at least one side wall being substantially horizontal, the corrugation in one mating side wall being non-parallel to the corrugation in the other mating side wall.
A bottle comprising a top portion, a bottom and side walls defining a receptacle, said bottle having two side walls constructed and arranged to permit stacking of two of said bottles when stacked with their opposed side walls mated and side wall reinforcing corrugation, a portion of the side wall reinforcing corrugation being substantially vertical and another portion of the side reinforcing corrugation being substantially horizontal, so as to reinforce the bottle against both horizontal and vertical forces, and a corrugation-free side wall portion on the side wall having the horizontal side wall reinforcing corrugation, disposed between said horizontal corrugation and the bottom to absorb shock from droppage.
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.
A bottle comprising a body defining a receptacle, said body having a rectangular cross-section and four faces, a top, and a bottom, two of said faces being first and second opposed parallel mating faces, the first opposed parallel mating face having vertical reinforcing corrugation and a plurality of mating projections formed in and integral with said vertical corrugation, and the second opposed parallel mating faces having horizontal reinforcing corrugation and a depressed region indented into the second opposed parallel mating face, said depressed region being sized complementary to the mating projections formed in the vertical corrugation of the first opposed parallel mating face to permit mating thereof, the mating face having horizontal reinforcing corrugation also having corrugation-free face portions between said horizontal corrugation and the top and the bottom to absorb shock from droppage.
