Abstract: A pressurized dispensing system including a plastic bottle and a method of minimizing the formation of stress cracks in a plastic bottle that is a part of a pressurized dispensing system. In a method of manufacturing the pressurized dispensing system, a plastic bottle is filled with a liquid, a valve is crimped onto the plastic bottle, and the plastic bottle is filled with gas so as to pressurize the plastic bottle. The plastic bottle is supported only in the finish region throughout the liquid filling, valve crimping, and gas filling steps. The filled and pressurized plastic bottle is substantially free of stress cracks.

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.

Abstract: A plastic bottle for containing a product under pressure, such as a product to be dispensed as an aerosol. The plastic bottle includes a rounded base, a body extending about an axis of the bottle from the base towards a top end of the bottle, and a finish at the top end of the bottle. The base and the finish are configured to eliminate or to reduce undesirable properties such as bursting, splintering when dropped, and stress cracking.

Abstract: A container for a pressurized dispensing system. The container includes a plastic bottle and a base cup bonded to a rounded bottom of the plastic bottle with a hot melt adhesive. The base cup has a bottom surface that allows the container to stand upright. A method of forming the container is also provided wherein hot melt adhesive is deposited in a recessed region in a top wall of a pedestal of the base cup, and a center region of the rounded bottom of the plastic bottle is pressed against the hot melt adhesive such that the adhesive spreads out over the recessed region and the rest of the top wall of the pedestal. After the hot melt adhesive cools, the bottle is securely bonded to the base cup.
