TODAY’S PATENT – PLASTIC BOTTLE

The PLASTIC BOTTLE was invented by John A. Snyder (Bridgewater, NJ), Robert L. Wechsler (Bridgewater, NJ) on 9^th of March, bearing the patent number US4318489A.

This invention pertains to bottles for holding liquids, and in particular the invention concerns one-piece, self-standing, plastic bottles suitable for containing carbonated beverages or other liquids under pressure.

The bottle is a one-piece, self-standing biaxially-oriented plastic container, with a cylindrical body and bottom from which several lobes or feet extend for supporting the bottle upright on a surface. The feet are also spherical and extend downwardly from the container bottom adjacent to the sidewall of the cylindrical body. The center of the bottom of the bottle may be depressed inwardly into the bottle to increase the clearance between the bottom and surface on which the bottle stands. The configuration of the bottle helps to provide adequate strength and good resistance to eversion. The bottle can be made with a minimal amount of plastic for given performance characteristics, and at speeds that are economical, even for relatively small bottles.
