  • Plastic bottle for containing both under-pressure and non under-pressure liquids
    Patent number: 5261543
    Abstract: A substantially cylindrical plastic bottle has a base including a plurality of bulges separated by arcuate ribs. Outer surfaces of the bulges extend vertically down to the bottoms thereof defining a bearing surface of the bottle. The ribs and the bulges extend inwardly to a spherically concave common portion of the base located at the central longitudinal axis of the bottle. The bottle also has a plurality of similar recesses extending therein in a regular pattern at the same height and separated by respective vertical ribs so as to facilitate a gripping and handling of the bottle. The bottle is thus suitable for packaging pressurized and non-pressurized liquids.
