ABSTRACT:
A glass container of the type designed to be coated with a plastic material to reduce breakage and shattering. The glass container has a neck portion which terminates in a discharge opening, a mid-portion and a base having a bearing surface upon which said bottle stands. The base comprises a plurality of concentric annular ribs as longitudinal extensions defining first and second annular channels and a central reservoir which are concentric about the center of the base with the first channel being outside the second channel. The channels and the reservoir are dimensioned and located to be filled with a charge of cast plastic. When the base is coated in this manner shattering and fragmentation of the container at the base is reduced.
