Abstract
A pressurized dispensing system includes a plastic bottle. The plastic bottle includes a crimp ring extending outwardly from a finish of the bottle, with first and second sealing projections extending from an upper surface of the crimp ring. A slot extends inwardly from an outer surface of the crimp ring, with the slot including a first section adjacent to the upper surface that is a further distance from an axis of the bottle than the second sealing projection is positioned from the axis of the bottle. The slot forms a passageway for gas to be released from the bottle when the system is heated. A valve is crimped to the crimp ring and a gasket is positioned between the upper surface and the valve such that a seal is formed between the bottle and valve.
