Today in 1973, US Patent 3760968 A was issued, an invention of S. Amberg, C. Heyne, and J. Meincer, assigned to Owens Illinois Inc., for their “Composite Container Article” Here’s the Abstract:

The invention disclosed relates to an improved container article for pressurized products, such as beer, beverages, and the like, which is made from a glass bottle or jar and a sheet of shrinkable plastic material pre-decorated as flat sheet, then wrapped on a mandrel to a sleeve that is telescopically inserted over the major side wall of the bottle so that a lower marginal end thereof overhangs the bottom end of the bottle. The sleeve may be of a pre-foamed or non-foamed plastic material and is shrunken in situ by heat so that it fits snugly on the bottle surface and conforms to the body around its shoulder, side wall and its lower corner radius or heel and onto the bottom end of the bottle protecting the glass against surface damage, providing a pre-printed label or decoration for the bottle and covering the bearing surface and lower corner radius of the bottle protecting those areas plus affording coaster protection to furniture or like surfaces. The orientation of the plastic is major on the peripheral dimension of the sleeve and minor on the axial dimension. Antistatic compounds are applied to the surface opposite the printed surface also priming the bottle for good cohesion of the sleeve. The plastic sleeve has a skin depth differential, the thicker skin being adjacent the bottle.
